1.1 Current Situation and Pain Points of Traditional Pig Breeding
For a long time, small and medium-sized pig farms and free-range households have mostly adopted manual feeding or simple semi-mechanized feeding methods. This traditional breeding mode has prominent inherent defects, which seriously restrict the scale and benefit improvement of the pig breeding industry. First, labor costs are high. Manual feeding requires a large number of breeders to complete feeding, material checking, and material supplementing work. With the continuous rise of domestic labor prices, the labor expenditure of pig farms accounts for an increasing proportion of breeding costs, and the profit space of breeding enterprises is continuously compressed. Second, the feeding accuracy is poor and feed waste is serious. Manual feeding relies on the personal experience of breeders, and the feeding amount cannot be accurately quantified. Excessive feeding will lead to feed residue and mildew, while insufficient feeding will affect the growth and development of pigs. In addition, the open feeding mode is easy to cause feed contamination by dust, bacteria, and pests, further increasing breeding costs and health risks.
Third, biological safety risks are prominent. Frequent manual entry and exit of the pig house will bring external bacteria, viruses, and pollutants into the breeding environment, increasing the probability of swine diseases such as swine fever and respiratory diseases. At the same time, manual feeding cannot achieve isolated feeding of different pens and different growth stages of pigs, which is not conducive to the segmented disease prevention and control system of large-scale pig farms. Fourth, the breeding management data is missing. Traditional manual feeding cannot record feeding data in real time, and it is impossible to accurately monitor the feed intake, growth status, and feeding rules of pig groups, resulting in blind breeding management, unable to realize refined breeding and scientific decision-making.
1.2 Industry Upgrade Demand for Large-Scale Intelligent Breeding
In recent years, driven by national agricultural modernization policies and market demand, China’s pig breeding industry has completed a rapid transformation from scattered free-range to large-scale and intensive breeding. According to the statistical data of the China Animal Husbandry Association, the scale rate of China’s pig breeding industry has exceeded 75% in 2025, and the number of large-scale pig farms with an annual output of more than 10,000 heads has increased year by year. Large-scale breeding puts forward higher requirements for feeding efficiency, feeding accuracy, biological safety, and refined management. The traditional manual and semi-mechanized feeding modes can no longer adapt to the production rhythm of modern large-scale pig farms.
At the same time, the continuous rise of feed raw material prices such as corn and soybean meal has made feed cost the largest proportion of pig breeding costs, accounting for more than 60% of the total breeding cost. Reducing feed waste and improving feed utilization rate have become the core means for breeding enterprises to reduce costs and increase efficiency. In addition, the state has continuously strengthened the supervision of animal husbandry breeding environmental protection and biological safety, and standardized and intelligent breeding equipment has become the mandatory supporting facilities for compliant production of pig farms. Under this industry background, fully automatic pig feeding line breeding equipment has become the standard configuration of modern large-scale pig farms, and the market penetration rate continues to rise.
1.3 Core Application Value of Automatic Feeding Line Equipment
The fully automatic pig feeding line for large-scale pig farms takes "intelligent precision feeding, efficient cost reduction, safe and standardized breeding, and data-based management" as the core value, and solves various pain points of traditional breeding in an all-round way. In terms of cost control, the equipment realizes precise quantitative feeding, effectively reduces feed waste, and improves feed utilization rate by 8%-15% compared with manual feeding. At the same time, it replaces a large number of manual operations, reduces the number of on-site breeders of pig farms by more than 60%, and greatly reduces labor costs and management costs.
In terms of breeding efficiency, the automatic feeding line operates 24 hours stably, realizes timed and quantitative feeding according to the growth cycle of pigs, ensures the scientific feeding of pig groups, promotes the healthy growth of pigs, shortens the feeding cycle, and improves the slaughter rate and breeding benefit of pigs. In terms of biological safety, the fully closed feeding mode isolates the feed from the external environment, avoids dust and bacterial pollution, and reduces the risk of pig group infection. The unmanned feeding mode reduces the frequency of personnel entering and exiting the pig house, and builds a safe breeding isolation barrier. In terms of refined management, the intelligent control system can record feeding data in real time, form big data analysis reports, help breeders accurately grasp the growth status of pig groups, and realize scientific breeding and intelligent decision-making.
二、Overall Structure and Working Principle of Automatic Feeding Line Equipment
The fully automatic pig feeding line breeding equipment for large-scale pig farms is a complete set of intelligent feeding system integrating storage, conveying, control, metering, and feeding. The whole set of equipment has a modular design, with stable structure, convenient installation and strong compatibility. It can be adapted to various types of closed pig houses such as gestation houses, farrowing houses, nursery houses, and fattening houses. The whole system is mainly composed of feed storage system, power conveying system, intelligent control system, precision metering feeding system, and anti-blocking and anti-pollution auxiliary system. Each module cooperates with each other to realize fully automatic unmanned feeding operation.
2.1 Feed Storage System
The feed storage system is the front-end storage guarantee of the automatic feeding line, mainly composed of galvanized sheet or stainless steel feed tower and feeding hopper. The feed tower is the core storage equipment, which is divided into vertical and horizontal types according to the installation form. The vertical feed tower is widely used in large-scale pig farms, with a capacity ranging from 5 tons to 50 tons, which can meet the daily feed demand of large pig groups and realize centralized storage of feed. The feed tower body is made of hot-dip galvanized steel plate or 304 stainless steel, which has the characteristics of anti-corrosion, rust prevention, rain proof and moisture proof, and can effectively avoid feed mildew and deterioration caused by damp.
The bottom of the feed tower is equipped with a conical blanking structure and a manual and electric dual-purpose switch, which is convenient for automatic blanking and manual maintenance and cleaning. The top of the feed tower is equipped with a dust-proof and rain-proof cover and a ventilation device, which can maintain the dryness and air circulation inside the tower, prevent feed agglomeration and mildew, and ensure the quality of stored feed. The feeding hopper is installed at the starting end of the conveying line, which plays the role of transition and buffer feeding, matching with the feed tower to realize continuous and stable feeding of the conveying system.
2.2 Power Conveying System
The power conveying system is the core power and transmission component of the feeding line, which undertakes the task of transporting feed from the feed tower to each feeding trough accurately and stably. According to different transmission structures, it is mainly divided into two mainstream types: auger conveying type and disc chain conveying type, which are suitable for different farm scales and pig house layouts.
The auger conveying system is composed of a spiral auger, drive motor, conveying pipe and fixing bracket. It has a simple structure and low manufacturing cost, and is suitable for short-distance and small-range feeding scenarios such as nursery houses and single-row fattening houses. The spiral auger rotates to push the feed forward, with stable conveying and low failure rate in short-distance operation. However, it has limitations such as single-row layout and poor adaptability to complex pig houses, and the later maintenance frequency is relatively high.
The disc chain conveying system is composed of a high-strength plastic disc, stainless steel chain, drive motor, tensioning device and closed conveying pipe. It is the mainstream configuration of current large-scale pig farms. The disc chain structure can realize long-distance and multi-unit series conveying, adapt to complex multi-row and multi-span pig house layouts, and has strong layout flexibility. The fully closed conveying pipeline completely isolates the feed from the external environment, which can effectively prevent feed pollution and moisture, and has outstanding advantages in biological safety. At the same time, the disc chain conveying has low noise, low wear and long service life, and can operate stably for a long time without frequent maintenance.
2.3 Intelligent Control System
The intelligent control system is the brain of the automatic feeding line, which determines the intelligent level and operation accuracy of the whole equipment. The mainstream feeding line adopts PLC programmable controller as the core, matched with touch screen operating terminal, remote monitoring module, sensor sensing device and fault alarm system, realizing full intelligent automatic control of the feeding process.
The PLC controller supports customized programming, and breeders can set multi-stage feeding parameters according to the growth characteristics of pregnant sows, lactating sows, nursery piglets and fattening pigs, including feeding time, feeding frequency, single feeding amount and daily feeding total amount. The system can automatically execute the feeding plan according to the set parameters, realizing timed, quantitative and fixed-point precise feeding. The touch screen terminal is installed on the pig house site, with a simple and intuitive operation interface, which can manually adjust parameters, view equipment operation status and feeding data in real time.
With the support of the IoT remote monitoring module, the equipment can realize mobile phone and computer remote control. Breeders can remotely start and stop the equipment, adjust feeding parameters, and view real-time feeding data and historical records without entering the pig house. The built-in high-precision sensors include material level sensors, pressure sensors and speed sensors, which can monitor the feed storage status of the feed tower, the operating speed of the conveying line and the feeding status in real time. Once there are faults such as material blockage, material shortage and equipment stall, the system will automatically alarm and stop the operation to avoid equipment damage and feeding interruption.
2.4 Precision Metering and Feeding System
The precision metering and feeding system is the key component to ensure feeding accuracy, which is composed of high-precision weighing sensor, metering barrel, automatic blanking valve and feeding trough. Different from the traditional fixed-volume feeding mode, the current mainstream automatic feeding line adopts weight-based metering, with a metering accuracy of ±30g and a single feeding error of less than 1%, which far exceeds the accuracy level of manual feeding and ordinary semi-automatic equipment.
The high-precision weighing sensor is installed at the bottom of the metering barrel. Before each feeding, the system automatically weighs the feed in the metering barrel, compares it with the set feeding amount, and accurately adjusts the blanking amount to ensure that each pig pen obtains the exact matching feed amount. For breeding pigs in different growth stages, the system can realize independent metering and variable feeding, for example, increasing the feeding amount of lactating sows according to lactation demand, and reducing the feeding amount of piglets in the nursery stage to avoid indigestion caused by overfeeding.
The feeding trough is made of stainless steel or food-grade plastic, with smooth surface, no feed residue, easy to clean and disinfect, and good antibacterial performance. The trough has a scientific structural design, which can effectively prevent pigs from arching feed and causing waste, and further improve the feed utilization rate. The modular feeding structure can be matched with pig pens of different specifications, realizing one-to-one precise feeding of single pen pigs.
2.5 Auxiliary Protection System
The auxiliary protection system includes anti-blocking device, dust removal device, moisture-proof and mildew-proof device and safety protection device, which is an important guarantee for the stable and long-term operation of the equipment. The anti-blocking device is installed at the corner and blanking port of the conveying line. Through vibration and anti-blocking structure design, it can effectively avoid feed blockage caused by feed agglomeration and excessive particle accumulation, ensuring smooth conveying of feed.
The fully closed pipeline is matched with a micro-dust removal device, which can absorb the dust generated during feed conveying, avoid dust floating in the pig house, improve the breeding environment, and reduce the respiratory diseases of pigs. The moisture-proof and mildew-proof system cooperates with the ventilation and drying device of the feed tower to keep the whole feeding line in a dry state, prevent feed from absorbing moisture and deteriorating during conveying, and ensure feed feeding safety. The safety protection device includes motor overload protection, circuit leakage protection and equipment limit protection, which can automatically cut off the power and stop the machine in case of overload, short circuit and abnormal operation, effectively protecting the equipment and breeding safety.
2.6 Overall Working Principle of the System
After the whole set of automatic feeding line equipment is installed and debugged, the breeder sets the feeding plan through the PLC control terminal according to the growth stage, number of pigs and breeding standards of the pig group. The feed is stored in the outdoor feed tower in a centralized manner, and the system automatically opens the blanking switch of the feed tower according to the set time, and the feed enters the conveying pipeline through the transition hopper. Driven by the power motor, the disc chain or auger conveying structure transports the feed to the metering barrels of each pig pen in turn.
After the high-precision weighing sensor completes accurate metering, the system automatically opens the blanking valve to deliver the feed to the feeding trough, completing one automatic feeding. After the feeding is completed, the system automatically cleans the residual materials in the pipeline and delays shutting down the equipment to avoid material blockage. In the whole process, the sensor monitors the equipment operation status and feeding data in real time, transmits the data to the control terminal and remote platform, and forms a feeding data report. If any fault occurs, the system will trigger an alarm prompt to realize unattended automatic feeding and intelligent monitoring of the whole process.
三、Classification and Applicable Scenarios of Automatic Feeding Line Equipment
According to different conveying modes, feeding forms and applicable breeding stages, large-scale pig farm automatic feeding lines can be divided into multiple types, with obvious differences in structural performance, cost investment and applicable scenarios. Scientific selection according to the actual scale of the farm, pig house layout and breeding variety is the key to giving full play to the equipment efficiency.
3.1 Classification by Conveying Structure
3.1.1 Auger Type Automatic Feeding Line
The auger type feeding line relies on spiral auger rotation to push feed conveying, with simple mechanical structure, low equipment cost and convenient installation and maintenance. The equipment has low requirements for pig house layout and is suitable for small and medium-sized large-scale pig farms, single-row pig houses and transformation and upgrading of old pig houses. The conveying distance of the auger type feeding line is limited, generally within 50 meters, and it is mostly used for independent feeding of a single pig house, which cannot realize cross-house series conveying.
This type of equipment is suitable for dry feed conventional feeding, with stable operation and low failure rate in daily use. The later maintenance cost is low, and the wearing parts are easy to replace. The disadvantage is that the conveying pipeline is open locally, the dust is relatively large during operation, the feed is easy to contact with the external environment, and the biological safety performance is slightly poor. It is mainly applicable to nursery pig houses and fattening pig houses with low biological safety requirements and short conveying distance.
3.1.2 Disc Chain Type Automatic Feeding Line
The disc chain type feeding line is the mainstream high-end configuration of current large-scale standardized pig farms. It adopts fully closed pipeline conveying, and the feed is completely isolated from the external environment in the whole conveying process, with excellent dust-proof, moisture-proof and pollution-proof performance. The equipment supports long-distance and multi-span series conveying, with a maximum conveying distance of more than 500 meters, which can realize centralized feeding of multiple pig houses and multiple areas, and is suitable for large-scale pig farms with an annual output of more than 10,000 heads.
The disc chain transmission structure has low wear and low noise, stable long-term operation, long service life of equipment, and almost no material blockage failure. The intelligent matching degree is high, and it can be perfectly connected with the intelligent breeding management system to realize data-based refined feeding management. Although the one-time investment cost is higher than that of the auger type, the later maintenance cost is extremely low, the comprehensive benefit is higher, and it is suitable for standardized breeding scenarios such as sow gestation houses, farrowing houses and high-standard fattening houses with high biological safety requirements.
3.2 Classification by Feeding Form
3.2.1 Dry Material Automatic Feeding Line
Dry material feeding line is the most widely used feeding equipment in pig farms at present, which is applicable to all growth stages of pigs. It adopts dry pellet feed and powder feed for conveying and feeding, with simple equipment structure, wide material adaptability and convenient daily management. The dry material feeding line has fast conveying speed and high feeding efficiency, which can meet the high-intensity feeding demand of large groups of pigs. At the same time, the dry feed is not easy to deteriorate, and the equipment has low cleaning and maintenance pressure.
According to the intelligent degree, the dry material feeding line is divided into fixed quantitative feeding and intelligent variable feeding. The fixed quantitative type is suitable for fattening pig groups with uniform growth rules, and the intelligent variable type can adjust the feeding amount in real time according to the growth status of pigs, which is suitable for fine breeding of sows and piglets.
3.2.2 Liquid Automatic Feeding Line
The liquid feeding line is a new type of intelligent feeding equipment, which mixes feed and water in proportion to form liquid feed for feeding. It is mainly applicable to lactating sows, weaned piglets and finishing fattening pigs. Liquid feed has good palatability, is easy for pigs to digest and absorb, can effectively improve the feed intake of piglets and sows, reduce the stress response of weaned piglets, and improve the growth rate and survival rate of pig groups.
The liquid feeding line is equipped with an automatic batching and mixing system, which can realize precise proportioning of feed and water, uniform mixing and regular cleaning of the pipeline, avoiding feed fermentation and deterioration in the pipeline. The disadvantage is that the equipment structure is complex, the cost is high, and the pipeline needs to be cleaned regularly, which has high requirements for daily maintenance. It is mostly used in high-end intensive breeding farms and breeding sow farms.
3.3 Classification by Applicable Breeding Stage
3.3.1 Sow Special Feeding Line
The sow special automatic feeding line is designed for the physiological growth characteristics of pregnant sows and lactating sows. It supports multi-stage variable feeding, and can set different feeding amounts according to the gestation period, lactation period and empty period of sows. The equipment has high metering accuracy, which can avoid excessive feeding leading to sow obesity or insufficient feeding affecting fetal development and lactation capacity. At the same time, it is equipped with an individual identification system, which can realize independent feeding management for each sow, and record the feeding data of a single sow to facilitate the tracking and management of sow breeding performance.
3.3.2 Piglet Nursery Special Feeding Line
The nursery feeding line is optimized for the feeding characteristics of weaned piglets. It adopts small-flow precise feeding, low-speed conveying, and the feeding trough is designed to prevent feed residue and mildew. The equipment can realize frequent small-quantity feeding, adapt to the small appetite and frequent feeding characteristics of piglets, avoid feed waste and gastrointestinal discomfort of piglets, and effectively improve the weaned survival rate and growth uniformity of piglets.
3.3.3 Fattening Pig Special Feeding Line
The fattening pig feeding line focuses on high-efficiency and large-flow feeding, with fast conveying speed and large single feeding amount, which can meet the rapid growth and high feed demand of fattening pigs. The equipment has strong stability, low failure rate in high-intensity operation, and is suitable for large-scale group fattening breeding scenarios, effectively reducing the overall breeding cost of fattening pigs.
四、Core Advantages of Fully Automatic Feeding Line for Large-Scale Pig Farms
Compared with traditional manual feeding and semi-mechanized feeding equipment, the fully automatic pig feeding line has comprehensive advantages in cost control, breeding efficiency, biological safety, refined management and long-term benefit, which is the core equipment to help large-scale pig farms achieve standardized and intelligent upgrading.
4.1 Precision Feeding and Significant Feed Saving Effect
Feed cost is the main cost of pig breeding, and reducing feed waste is the key to reducing breeding costs. The traditional manual feeding error is large, and the feed waste rate is as high as 10%-20%. The fully automatic feeding line adopts high-precision weight metering technology, with a feeding accuracy error controlled within ±1%, realizing accurate quantitative feeding for each pen of pigs. According to the statistical data of large-scale breeding enterprises, after using the automatic feeding line, the feed utilization rate is increased by 8%-15%, and the feed waste is basically eliminated. For a large-scale pig farm with an annual output of 10,000 heads, the annual feed saving cost can reach hundreds of thousands of yuan, with very significant economic benefits.
At the same time, the equipment realizes scientific feeding according to the growth rules of pigs, avoids overfeeding and underfeeding, makes the nutrition intake of pig groups more balanced, improves the average daily gain and feed conversion rate of pigs, shortens the feeding cycle by 5-10 days, and further improves the breeding unit output benefit.
4.2 Greatly Reduce Labor Costs and Improve Operational Efficiency
Traditional pig farms need to be equipped with a large number of breeders to complete feeding, material checking, and material supplementing work, with high labor intensity and high personnel management costs. The fully automatic feeding line realizes full-process unmanned automatic feeding, and all feeding links such as feed storage, conveying, metering and feeding are completed by intelligent equipment without manual intervention. A large-scale pig farm with an annual output of 10,000 heads can reduce the number of on-site breeders from 8-12 to 2-3, and the labor cost is reduced by more than 70%.
The equipment can operate stably for 24 hours without interruption, realize timed and fixed-point feeding, avoid feeding delay and omission caused by manual negligence, and greatly improve the feeding efficiency and standardization level. The daily feeding work that originally took several hours to complete manually can be completed in tens of minutes by the automatic system, which greatly improves the operational efficiency of the farm and adapts to the high-efficiency production rhythm of large-scale breeding.
4.3 Closed Operation to Build a Solid Biological Safety Barrier
Biological safety is the bottom line of pig farm breeding production, and cross-infection caused by personnel and feed pollution is one of the main causes of pig diseases. The fully automatic feeding line adopts a fully closed design from feed tower storage to pipeline conveying and trough feeding, and the feed is completely isolated from the external environment in the whole process, avoiding dust, bacteria, viruses and pest pollution in the air, ensuring the cleanliness and safety of feed.
The unmanned feeding mode greatly reduces the frequency of personnel entering and exiting the pig house, avoids the introduction of external pathogens by personnel, and effectively reduces the incidence of swine diseases such as swine fever, blue ear disease and respiratory diseases. At the same time, the closed pipeline is convenient for overall disinfection and cleaning, which can realize regular disinfection and sterilization of the feeding system, eliminate hidden dangers of bacterial growth, and build a full-cycle biological safety protection system for the pig house.
4.4 Intelligent Data Management to Realize Refined Breeding
Traditional manual feeding cannot form standardized feeding data, and breeders can only rely on experience to manage breeding, resulting in extensive breeding management and difficult risk control. The intelligent automatic feeding line is equipped with a complete data monitoring and recording system, which can automatically record key data such as daily feeding amount, feeding frequency, single pen feed intake and equipment operation status of the pig farm, and form visual data reports.
Breeders can accurately judge the growth status, health status and appetite changes of pig groups through feeding data. For example, the sudden decrease in feed intake of individual pigs can be used as an early warning signal of diseases, realizing early discovery, early diagnosis and early treatment of pig diseases, and reducing breeding loss. At the same time, through the big data analysis of long-term feeding data, the farm can optimize the feeding plan, adjust the feed formula and feeding rhythm, realize personalized refined feeding for different growth stages and different health status of pigs, and greatly improve the scientific level of breeding management.
4.5 Stable Operation and Low Long-Term Comprehensive Cost
The fully automatic feeding line equipment adopts high-quality anti-corrosion, wear-resistant and rust-proof materials, with solid overall structure, strong weather resistance and long service life. The core transmission components such as disc chain and conveying pipe have low wear rate, stable long-term operation and low failure rate. Compared with the easy damage of semi-mechanized equipment, the later maintenance frequency and maintenance cost of the automatic feeding line are extremely low.
Although the one-time investment of automatic feeding line is higher than that of traditional equipment, the comprehensive cost advantage is prominent in the long-term operation cycle. Through saving feed cost, reducing labor cost, reducing disease loss and improving breeding efficiency, the equipment investment cost can be recovered in 1-2 years, and the long-term economic benefit is far higher than that of traditional feeding modes. At the same time, the standardized and intelligent equipment configuration improves the overall grade and compliant production capacity of the farm, which is conducive to the policy subsidy and scale expansion of the farm.
五、Equipment Installation, Commissioning and Daily Operation and Maintenance
The installation quality and daily maintenance level of the fully automatic feeding line directly determine the operation stability, feeding accuracy and service life of the equipment. Standardized installation and commissioning and scientific daily maintenance are important links to ensure the efficient operation of the equipment and give full play to its functional advantages.
5.1 Standard Installation and Commissioning Process
The installation of the automatic feeding line needs to follow the standardized process of "on-site survey - scheme design - component installation - line debugging - trial operation - formal operation". First, according to the pig house layout, farm scale and breeding demand, conduct on-site survey, confirm the installation position of the feed tower, the laying route of the conveying pipeline, the installation position of the control system and the feeding trough, and formulate a targeted installation scheme to avoid pipeline distortion, excessive bending and unreasonable layout.
In the equipment installation stage, install the feed tower first, fix the tower body firmly, do a good job of waterproof and anti-corrosion treatment, and ensure the verticality and stability of the feed tower. Then lay the conveying pipeline and install the power drive device, metering device and feeding trough in turn, ensuring that the pipeline is tightly connected without gaps, the transmission components operate flexibly, and the metering device is installed horizontally and fixed firmly. After the mechanical installation is completed, carry out the wiring installation and program debugging of the intelligent control system, set the basic parameters of the equipment, and test the sensor induction, remote control and fault alarm functions one by one.
After the installation is completed, conduct 24-hour uninterrupted trial operation, check whether there are faults such as material blockage, inaccurate metering, equipment noise and pipeline leakage, adjust the operating speed and metering parameters of the equipment, and optimize the feeding program according to the actual feeding situation of the pig group. After the trial operation is stable and meets the breeding standards, the equipment can be put into formal operation.
5.2 Daily Operation Specifications
In the daily operation process of the automatic feeding line, the breeder needs to abide by standardized operation specifications to ensure the stable operation of the equipment. First, check the equipment status before starting up every day, check whether the feed tower has sufficient feed, whether the conveying pipeline is blocked, whether the sensor and motor are normal, and start up the equipment after confirming that there is no abnormality.
Second, reasonably set the feeding parameters according to the growth stage and number of pig groups, adjust the feeding amount and feeding frequency in a timely manner with the growth of pigs, and avoid fixed parameter feeding leading to unreasonable nutrition matching. Third, monitor the equipment operation status in real time during operation, check the feeding uniformity of each pen, and deal with abnormal conditions such as material blockage and missing feeding in a timely manner. Fourth, standardize the shutdown operation, clean the residual materials in the pipeline after daily feeding, and avoid feed agglomeration and mildew in the pipeline for a long time.
5.3 Regular Maintenance and Maintenance Standards
Daily maintenance is the key to prolong the service life of the equipment and maintain high-precision operation. The daily maintenance work mainly includes cleaning, inspection, lubrication and anti-corrosion. Every day after the equipment is shut down, clean the feeding trough, pipeline residual materials and feed tower dust to keep the equipment clean and hygienic and avoid bacterial growth. Check the tightness of the pipeline connection, the wear of the transmission chain and auger, and the sensitivity of the sensor every day, and replace the worn parts in a timely manner.
Carry out regular lubrication maintenance on the motor, bearing and transmission gear every week to ensure flexible operation of mechanical components and reduce operation wear. Conduct a comprehensive inspection of the feed tower sealing performance, ventilation device and anti-corrosion layer every month to repair the damaged anti-corrosion coating in a timely manner and avoid tower body rust and moisture ingress. Conduct a comprehensive calibration of the metering system every quarter to ensure that the feeding accuracy is always within the standard range and avoid metering errors affecting feeding quality.
5.4 Common Faults and Troubleshooting Methods
In the long-term operation process of the automatic feeding line, occasional minor faults may occur due to feed quality, operation habits and equipment wear. Mastering common fault troubleshooting methods can effectively improve operation efficiency and reduce maintenance costs. First, material blockage fault: mostly caused by feed agglomeration and excessive pipeline bending. The solution is to clean the agglomerated feed in the pipeline, optimize the pipeline layout, and avoid excessive bending and dead corners.
Second, inaccurate feeding metering: caused by sensor deviation and metering barrel dirt accumulation. It is necessary to clean the metering barrel regularly and calibrate the weighing sensor to ensure metering accuracy. Third, equipment no-load operation and abnormal noise: mostly caused by loose transmission parts and lack of lubrication. It is necessary to fasten the fixed parts and add lubricating oil to the transmission components. Fourth, remote control failure: caused by network signal instability and system program error. It is necessary to check the network connection status regularly and restart the system to reset the program.
