Description

Technical Field

[0001] This invention belongs to the field of animal husbandry technology, and specifically relates to a timed automatic cleaning and precision feeding system and its working method. Background Technology

[0002] Animal husbandry is a production sector that utilizes the physiological functions of domesticated animals such as livestock and poultry, or wild animals such as deer, musk deer, foxes, minks, otters, and quails, through artificial breeding and raising to convert plant energy from pasture and feed into animal energy, producing livestock products such as meat, eggs, milk, wool, cashmere, hides, silk, and medicinal materials. Unlike subsistence livestock farming, animal husbandry is characterized by centralization, large-scale production, and profit-driven objectives. In the early stages of economic development, animal husbandry often manifested as a sideline to agricultural production, the so-called "backyard livestock farming." With economic development, it has gradually evolved into a relatively independent industry in certain sectors.

[0003] Livestock farming, including cattle, sheep, and pigs, is an important part of China's agricultural economy. China is also a major global producer and consumer of meat. Feeding methods have a crucial impact on farming efficiency. Proper feeding methods ensure animals receive sufficient nutrition, promote healthy growth, and improve farming profitability. Furthermore, proper feeding methods ensure animals receive balanced nutrition to meet their growth and development needs.

[0004] Traditional feeding methods still rely mainly on manual labor, with feeders mixing feed according to formulas and feeding the animals manually. They also regularly clean and disinfect the livestock sheds to keep them dry and well-ventilated.

[0005] Analysis of existing technologies reveals the following problems:

[0006] High dependence on manual labor: Traditional feeding methods involve animals constantly rooting for food, requiring manual intervention, which easily leads to deviations in feeding amount and timing, affecting animal health. Serious feed waste: Traditional feeding is easily affected by environmental factors, resulting in widespread feed mold and spillage. Inadequate hygiene management: Untimely removal of leftover food easily breeds bacteria, increasing the risk of animal disease. Summary of the Invention

[0007] This invention is implemented as follows:

[0008] This invention provides a timed automatic cleaning precision feeding system, wherein the system includes a feed mixer for mixing feed and a main conveyor belt for conveying feed. The feed mixer is located above one end of the main conveyor belt. A residual feed collector is fixedly installed on the end of the main conveyor belt near the feed mixer. A residue collector is fixedly installed on the end of the main conveyor belt away from the residual feed collector. Multiple feeding troughs are fixedly installed on one side of the main conveyor belt. A feed guide plate is rotatably installed on the other side of the main conveyor belt, opposite to the feeding troughs. A feeding trough conveyor belt is fixedly installed inside the feeding troughs. A flushing cleaner for cleaning the feeding trough conveyor belt and the main conveyor belt is fixedly installed directly below both the feeding trough conveyor belt and the main conveyor belt. A feed receiving plate is also fixedly installed at the junction of the feeding trough and the main conveyor belt.

[0009] The technical advantages of the timed automatic cleaning precision feeding system provided by this invention are as follows: Normally, to ensure animals reach their standard feed intake, the provided feed is usually greater than the animal's standard feed intake, but less than its maximum feed intake. During feeding, some mixed feed may not be fully consumed. By setting up a feed waste collector, the uniformly mixed but unconsumed feed can be recycled and reused. By setting up a residue collector, contaminated mixed feed and animal feeding residue can be recycled. Using the feed waste collector and residue collector, uncontaminated and contaminated feed are distinguished and recycled, and then processed accordingly. Compared with the traditional simultaneous collection method, this differentiated collection greatly reduces feed waste. By setting up a feed guide plate, feed is transported into the feeding trough. The guide plate's obstruction and the main conveyor belt's transmission action facilitate feed delivery into the feeding trough. By designing a feed receiving plate, leakage of feed is prevented when the feed passes between the main conveyor belt and the feeding trough conveyor belt.

[0010] Based on the above technical solution, the timed automatic cleaning and precision feeding system of the present invention can be further improved as follows:

[0011] Furthermore, a feed area partition plate is fixedly installed inside the feed trough, dividing the feed trough into a feeding area and a buffer area; an infrared sensor is fixedly installed on the feed area partition plate near the feeding area; a feed trough rear baffle is fixedly installed on the end of the feed trough away from the main conveyor belt; a gap is left between the feed trough rear baffle and the feed trough conveyor belt; a full feed sensor is fixedly installed on the feed trough rear baffle near the feeding area.

[0012] The beneficial effects of adopting the above-mentioned further solutions are as follows: by setting up infrared sensors, the feeding desire of animals can be reflected laterally, thereby automatically adjusting the feed delivery speed and achieving precise feeding by adjusting supply according to demand; by setting up full feed sensors, the amount of feed in the feeding trough can be precisely controlled.

[0013] Furthermore, the upper surface of the feed trough conveyor belt is higher than the upper surface of the main conveyor belt; there is a 2-5° angle between the feed receiving plate and the horizontal plane where the main conveyor belt is located.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: by setting the feed trough conveyor belt higher than the main conveyor belt and the inclined feed receiving plate, the feed can be smoothly transferred from the feed trough conveyor belt to the main conveyor belt when recycling leftover materials and cleaning up residues.

[0015] Furthermore, the spatial ratio of the feeding area to the buffer zone is 1:3.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: by setting up a buffer zone and a feeding zone, the feed is separated, which avoids the animals contaminating the clean feed that follows, thus preventing waste; at the same time, by setting up a buffer zone, a feeding buffer is provided, giving the system sufficient processing time.

[0017] Furthermore, the system also includes a controller, which specifically includes a core control unit, a motor unit, a guide plate unit, a feed trough sensing unit, and a rinsing and cleaning unit. The core control unit is a PLC of various models from Siemens. The motor unit controls the motors operating within the system, including the feeding motor inside the feed equalizer, the main conveyor motor in the main conveyor belt, and the feed trough conveyor motor in the feed trough conveyor belt. The motor unit also feeds back the data signals of each motor to the core control unit. The guide plate unit controls the feed guide plate. The feed trough sensing unit receives signals from the infrared sensor and the full feed sensor and transmits them to the core control unit. The rinsing and cleaning unit controls the rinsing and cleaning unit.

[0018] Furthermore, the core control unit is also externally connected to an alarm unit for issuing warnings and reminders to management personnel.

[0019] The present invention also provides a method for operating a timed automatic cleaning precision feeding system, wherein the method specifically includes:

[0020] Step S1: Timed feeding. Based on feeding needs and animal habits, the feeding time is adjusted to a fixed time period. The timer of the core control unit is used to keep track of the time. When the feeding time is reached, the timer starts, and the core control unit controls the motor in the feed mixer to start through the motor unit to mix the feed evenly.

[0021] Step S2, automatic distribution: The core control unit controls the opening and closing of the feed guide plates at the openings of multiple feed troughs through the full feed sensor, automatically delivering a fixed amount of feed into each feed trough.

[0022] Step S3, precise feeding: Based on experience, the manager adjusts the position of the full feed sensor to determine the minimum feed amount required by the animal when the feed trough is full; a feeding method is adopted, and the amount of feed pushed is determined by the animal's feed intake; the animal's feed intake is determined by an infrared sensor fixed to the feed area partition.

[0023] Step S4, leftover feed recycling: After the process of step S2, the animals have finished eating, but there will inevitably be leftover feed in the feeding trough. The main conveyor belt and the feeding trough conveyor belt are used to transport the feed in reverse to recycle the uncontaminated leftover feed. The recycled feed is then transported to the leftover feed recycler and then sent to the feed equalizer for circulation.

[0024] Step S5, residue cleaning: After the process of step S3, clean feed is recovered, and the remaining animals eat the residue and contaminated feed; the feed trough conveyor belt transports in reverse and the main conveyor belt transports in forward, transporting the animal food residue and contaminated feed in the feed trough to the residue collector for further processing.

[0025] Step S6, timed cleaning: Half an hour after the recycling process in step S3, the core control unit controls the flushing and cleaning unit to start the flushing and cleaning device to clean the feed trough conveyor belt and prevent contamination of the clean feed during the next feeding.

[0026] The technical effects of the timed automatic cleaning and precision feeding system provided by this invention are as follows: timed and quantitative feeding stabilizes the living habits of the fed animals and also better ensures the quality of the finished product after the animals reach maturity.

[0027] Furthermore, the specific process of step S2 includes:

[0028] Step S21: The main conveyor belt conveys the feed. The core control unit controls the motor in the main conveyor belt to start and rotate at high speed through the motor unit. The feed mixed in step S1 moves under the drive of the main conveyor belt. At this time, the feed guide plate at the corresponding opening of each feed trough is in the closed state.

[0029] Step S22, feed accumulation: The moving feed gathers into the feed trough under the obstruction of the feed guide plate, and is sent into the feed trough by the feed trough conveyor belt, and is finally blocked and accumulated by the feed trough rear baffle.

[0030] Step S23: Feed is added sequentially. When the full feed sensor is continuously triggered, it indicates that the amount of feed inside the feed trough has reached its maximum value. At this time, the feed guide plate opposite to the feed trough opening is switched to the open state, and feed is piled into the next feed trough. Step S22 is repeated.

[0031] Step S24, feeding stops; repeat the above process until the full sensor in the last feeding trough is continuously triggered, that is, the feed in the last feeding trough is full; at this time, the motor in the main conveyor belt stops rotating.

[0032] Step S25, subsequent feeding: The position of the full feed sensor in the feeding trough is set in advance by the staff. During the animal's feeding process, the feed in the feeding area is consumed, and the feed in the buffer zone is replenished to the feeding area. When the feeding trough conveyor belt moves a distance of 1.5 times the length of the buffer zone, the corresponding feed guide plate turns to the closed state again, and the motor in the main conveyor belt starts to rotate again, repeating steps S22 to S24.

[0033] Furthermore, step S3 specifically includes: an infrared sensor is fixedly installed on the feed area partition plate, at a certain distance from the back baffle of the feed trough. When the animal is eating, it prioritizes the feed closest to the back baffle of the feed trough and gradually moves towards the feed closer to the feed area partition plate. During this movement, the infrared sensor is triggered, and the infrared sensor transmits a signal to the core control unit through the feed trough sensing unit. The core control unit receives the signal and controls the motor in the feed trough conveyor belt corresponding to the triggered infrared sensor to start, conveying the feed in the buffer zone to the feeding area. After the motor in the feed trough conveyor belt is triggered multiple times, the feed in the buffer zone is consumed. At this time, the feed guide plate switches to the closed state again, and the feed accumulates in the feed trough again. The above process is repeated until the animal's feeding time ends.

[0034] Furthermore, the feed guide plate at the last feed trough opening is closed until step S4 is performed.

[0035] Compared with existing technologies, the advantages of the timed automatic cleaning and precision feeding system provided by this invention are:

[0036] (1) Feed the animals precisely according to their individual differences to avoid the problems of not eating enough or not finishing their food;

[0037] (2) Recycle leftover materials to avoid waste;

[0038] (3) Collect feed residues to avoid environmental pollution;

[0039] (4) Clean regularly to prevent bacterial growth. Attached Figure Description

[0056] Optionally, in the above technical solution, the upper surface of the feed trough conveyor belt 51 is higher than the upper surface of the main conveyor belt 3; there is a 2-5° angle between the feed receiving plate 53 and the horizontal plane where the main conveyor belt 3 is located.

[0057] Optionally, in the above technical solution, the spatial ratio of the feeding area 56 to the buffer zone 57 is 1:3. Optionally, in the above technical solution, the core control unit is also externally connected to an alarm unit for issuing warnings and reminders to management personnel.

[0058] Optionally, in the above technical solution, baffles are provided on both sides of the main conveyor belt 3 to prevent feed from scattering outside the conveyor belt during the feed conveying process.

[0059] Optionally, in the above technical solution, the rinsing cleaner 6 is not only used in the final rinsing and cleaning process, but also the brush on the rinsing cleaner 6 will perform preliminary cleaning of the feed trough conveyor belt 51 during the feeding process to prevent the feed in the buffer zone 57 from being contaminated during the repeated operation of the feed trough conveyor belt 51.

[0060] Optionally, in the above technical solution, the system also includes a controller, which specifically includes a core control unit, a motor unit, a guide plate unit, a feed trough sensing unit, and a rinsing and cleaning unit; the core control unit is a PLC of various models from Siemens; the motor unit is used to control the motors operating within the system, including the feeding motor inside the feeder 2, the main conveyor motor inside the main conveyor belt 3, and the feed trough conveyor motor inside the feed trough conveyor belt 51, and the motor unit is also used to feed back the data signals of each motor to the core control unit; the guide plate unit is used to control the feeding guide plate 52; the feed trough sensing unit is used to receive signals from the infrared sensor 541 and the full feed sensor 551 and transmit them to the core control unit; the rinsing and cleaning unit is used to control the rinsing and cleaning unit 6.

[0061] Optionally, in the above technical solution, the core control unit is also externally connected to an alarm unit for issuing warnings and reminders to management personnel.

[0062] like Figure 4 , 5 As shown, the present invention also provides a method for operating a timed automatic cleaning precision feeding system, wherein the method specifically includes:

[0063] Step S1: Timed feeding. Based on feeding needs and animal habits, the feeding time is adjusted to a fixed time period. The timer of the core control unit is used to keep track of the time. When the feeding time is reached, the timer starts, and the core control unit controls the motor in the feeder 2 to start through the motor unit to mix the feed evenly.

[0064] Step S2, automatic distribution: The core control unit controls the opening and closing of the feed guide plates 52 at the openings of multiple feed troughs 5 through the full feed sensor 551, and automatically delivers a fixed amount of feed into each feed trough 5.

[0065] Step S3, precise feeding: Based on experience, the manager adjusts the position of the full feed sensor 551 to determine the minimum feed amount required by the animal when the feed trough 5 is full. The feeding method is adopted, and the amount of feed pushed is determined by the animal's feed intake. The animal's feed intake is determined by the infrared sensor 541 fixed on the feed area partition plate 54.

[0066] Step S4, leftover feed recovery: After step S2, the animals have finished eating, but inevitably there will be leftover feed in the feeding trough 5. At this time, the main conveyor belt 3 and the feeding trough conveyor belt 51 transport the feed in reverse. The uncontaminated leftover feed is driven by the feeding trough conveyor belt 51 into the main conveyor belt 3. The main conveyor belt 3 drives the uncontaminated feed to move in reverse, transporting the feed to the leftover feed collector 1, and then through the leftover feed collector 1 to the feed equalizer 2 for circulation. During this process, the feeding trough conveyor belt 51 does not operate continuously. If the feeding trough conveyor belt 51 operates continuously, it will bring in contaminated feed, eventually causing all the recovered feed to be contaminated. Because the feeding trough 5 is divided into a feeding area 56 and a buffer zone 57, and there is a feed area partition plate 54 as a barrier, the feed behind the feed area partition plate 54 can be considered clean. Since the feed area partition plate 54 is fixed, the reverse movement distance of the feeding trough conveyor belt 51 is fixed.

[0067] Step S5, residue cleaning: After the process of step S3, clean feed is recovered, and the remaining animals eat the residue and contaminated feed; the feed trough conveyor belt 51 transports in reverse, and the main conveyor belt 3 transports in forward, transporting the animal-eaten residue and contaminated feed in the feed trough 5 to the residue collector 4 for further processing; during this process, the feed trough conveyor belt 51 continues to move in reverse until all the residue and contaminated feed have been transported.

[0068] Step S6, timed cleaning: Half an hour after the recycling process in step S3, the core control unit controls the flushing and cleaning unit to start the flushing and cleaning device 6 to clean the feed trough conveyor belt 51, so as to avoid contamination of the clean feed during the next feeding.

[0069] Optionally, in the above technical solution, step S2 includes the following specific process:

[0070] In step S21, the main conveyor belt conveys the feed. The core control unit controls the motor in the main conveyor belt 3 to start and rotate at high speed through the motor unit. The feed mixed in step S1 moves under the drive of the main conveyor belt 3. At this time, the feed receiving plate 53 at the corresponding opening of each feed trough 5 is in the closed state.

[0071] Step S22, feed accumulation: The moving feed gathers into the feed trough 5 under the obstruction of the feed receiving plate 53, and is sent into the feed trough 5 by the feed trough conveyor belt 51, and is finally blocked and accumulated by the feed trough rear baffle 55.

[0072] Step S23: Feed is added sequentially. When the full feed sensor 551 is continuously triggered, it indicates that the amount of feed inside the feed trough 5 has reached its maximum value. At this time, the feed guide plate 52 opposite to the opening of the feed trough 5 is switched to the open state, and feed is piled into the next feed trough 5. Step S22 is repeated.

[0073] Step S24, feeding stops; repeat the above process until the full feed sensor 551 in the last feed trough 5 is continuously triggered, that is, the feed in the last feed trough 5 is full; at this time, the motor in the main conveyor belt 3 stops rotating.

[0074] In step S25, subsequent feeding occurs. The position of the full feed sensor 551 in the feed trough 5 is set in advance by the staff. During the animal's feeding process, the feed in the feeding area 56 is consumed, and the feed in the buffer zone 57 is replenished to the feeding area 56. When the feed trough conveyor belt 51 moves a distance of 1.5 times the length of the buffer zone 57, the corresponding feed guide plate 52 turns to the closed state again, and the motor in the main conveyor belt 3 starts to rotate again, repeating steps S22 to S24.

[0075] Optionally, in the above technical solution, the running speed of the main conveyor belt 3 is V, the distance from the outlet of the feeder 2 to the first feed trough 5 is L1, and after a time T1=L1 / V, the feed reaches the feed guide plate 52 of the first feed trough 5. The feed on the main conveyor belt 3 accumulates into the feed trough 5 under the guidance. A feed trough conveyor belt 51 is installed inside the feed trough 5, the running speed of the feed trough conveyor belt 51 is V1, the length of the feed trough 5 is S, and after a time Δt1=S / V1, the feed reaches the feed trough rear baffle 55. When the feed accumulates to a certain height inside the feed trough rear baffle 55, the feed is installed at the feed trough rear baffle. When the feed level sensor 551 on plate 55 is triggered, it sends a signal to the core control unit. The core control unit determines that the feed level inside the feed trough 5 has reached the set value. The core control unit then controls the feed guide plate 52 to open, allowing the feed to accumulate in the next feed trough 5. If the feed level sensor 551 is not triggered within a 10-minute interval, and the core control unit does not receive a signal from the feed level sensor 551, it indicates a problem with the feed conveying system. The core control unit issues an alarm signal, and staff can determine the feed trough 5 that has malfunctioned based on the number of time intervals.

[0076] Optionally, in the above technical solution, step S3 specifically includes: the infrared sensor 541 is fixedly installed on the feed area partition plate 54, at a certain distance from the feed trough back baffle 55. When the animal is eating, it prioritizes the feed near the feed trough back baffle 55 and gradually pushes the feed closer to the feed area partition plate 54. During the above-mentioned pushing process, the infrared sensor 541 is triggered. The infrared sensor 541 transmits the signal to the core control unit through the feed trough sensing unit. The core control unit receives the signal and controls the motor in the feed trough conveyor belt 51 corresponding to the triggered infrared sensor 541 to start, so as to transport the feed in the buffer zone 57 to the feeding area 56. After the motor in the feed trough conveyor belt 51 is triggered multiple times, the feed in the buffer zone 57 is consumed. At this time, the feed guide plate 52 switches to the closed state again, and the feed accumulates in the feed trough 5 again. The above process is repeated until the animal's feeding time ends.

[0077] Optionally, in the above technical solution, the feed guide plate 52 at the opening of the last feed trough 5 is in a closed state until step S4 is performed.

[0078] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.

Step S5, residue cleaning: After the process of step S3, clean feed is recovered, and the remaining animals eat the residue and contaminated feed; the feed trough conveyor belt (51) transports in reverse and the main conveyor belt (3) transports in forward, transporting the animal food residue and contaminated feed in the feed trough (5) to the residue collector (4) for subsequent processing. Step S6, timed cleaning: Half an hour after the recycling process in step S3, the core processing unit controls the flushing and cleaning unit to start the flushing and cleaning device (6) to clean the feed trough conveyor belt (51) to prevent contamination of clean feed during the next feeding.

7. The working method of the timed automatic cleaning precision feeding system according to claim 6, characterized in that, The specific process of step S2 includes: In step S21, the main conveyor belt transports the feed. The core processing unit controls the motor in the main conveyor belt (3) to start and rotate at high speed through the motor unit. The feed mixed in step S1 moves under the drive of the main conveyor belt (3). At this time, the feed guide plate (52) at the opening of each feed trough (5) is closed. Step S22, feed accumulation: The moving feed gathers into the feed trough (5) under the blocking action of the feed guide plate (52), and is sent into the feed trough (5) by the feed trough conveyor belt (51), and is finally blocked and accumulated by the feed trough rear baffle (55). Step S23: Feed is added sequentially. When the full feed sensor (551) is continuously triggered, it indicates that the amount of feed inside the feed trough (5) has reached its maximum value. At this time, the feed guide plate (52) opposite to the opening of the feed trough (5) is switched to the open state, and feed is piled into the next feed trough (5). Step S22 is repeated. Step S24, feeding stops; repeat the above process until the full feed sensor (551) in the last feed trough (5) is continuously triggered, that is, the feed in the last feed trough (5) reaches the full state; at this time, the motor in the main conveyor belt (3) stops rotating; In step S25, subsequent feeding: the position of the full feed sensor (551) in the feed trough (5) is set in advance by the staff. During the animal's feeding process, the feed in the feeding area (56) is consumed, and the feed in the buffer zone (57) is replenished to the feeding area (56). When the feed trough conveyor belt (51) moves a distance of 1.5 times the length of the buffer zone (57), the corresponding feed guide plate (52) turns into the closed state again, and the motor in the main conveyor belt (3) starts to rotate again, repeating steps S22 to S24.

8. The working method of the timed automatic cleaning precision feeding system according to claim 7, characterized in that, Until step S4 is performed, the feed guide plate (52) at the opening of the last feed trough (5) is in a closed state.
