Technical Field

[0001] The present invention relates to the technical field of agricultural equipment, and in particular to a feed metering device for achieving precise feeding. Background Art

[0002] Feeding refers to feeding animals with feed. Feeding should be done according to feeding regulations. The trough should not be piled up or left empty. The fine and coarse feeds should be properly mixed. Feeding should be done at regular times and in fixed quantities. Feed small amounts frequently and add more frequently. Do not feed moldy, spoiled, or frozen feed.

[0003] In existing animal husbandry and feed processing enterprises, accurate feed supply is an important factor in ensuring animal health and production performance. Traditional feeding methods often rely on manual operation, which easily leads to feed waste or insufficient supply, resulting in poor accuracy of feed supply during animal feeding. Therefore, a feed metering device for achieving precise feeding is proposed. Summary of the Invention

[0006] The blanking assembly includes an electric push rod and a second baffle, a horizontal plate is fixed to the push rod end of the electric push rod, and a protrusion is fixed to one side of the second baffle.

[0007] Preferably, a first baffle and a push plate are fixed to the top of the horizontal plate, a second discharge hole is opened on one side of the first baffle, and the outer side of the first baffle is seamlessly inserted into and slidably connected to one side of the discharge pipe.

[0008] Preferably, a first guiding inclined surface is provided on one side of the top of the push plate, a second guiding inclined surface is provided on one side of the protrusion, and a first discharge hole is provided on one side of the second baffle.

[0009] Preferably, the outer side of the second baffle is seamlessly inserted into and slides on one side of the discharge pipe, and a limiting block is fixed on one side of the top of the second baffle.

[0010] Preferably, a slide rod is movably passed through one side of the limit block, a tension spring is sleeved on the outer side of the slide rod, and two ends of the tension spring are respectively connected to one side of the limit block and the discharge pipe.

[0011] Preferably, the cleaning assembly comprises a box body, a motor is fixed to the inner wall of the box body, a reciprocating screw is fixed to the output shaft end of the motor, and a scraper is threadedly connected to the inner wall of the feeding trough on the outer side of the reciprocating screw body.

[0012] Preferably, a sliding column is fixed to the inner wall of the feeding trough, the outer side of the sliding column is movable and passes through one side of the scraper, and a through groove is opened on one side of the bottom of the feeding trough.

[0013] Preferably, a plurality of heat dissipation holes are provided on one side of the box body, and the box body is fixed to one side of the feeding trough.

[0014] Preferably, a PLC controller is installed on the inner wall of the fixing frame, a maintenance door is connected to one side of the fixing frame via a hinge, and the bottom of the electric push rod is fixed to the bottom of the inner wall of the fixing frame.

[0015] Preferably, the output end of the weight sensor is electrically connected to the input end of the PLC controller, and the output end of the PLC controller is electrically connected to the input ends of the electric push rod and the motor respectively.

[0016] Compared with the prior art, the present invention adopts the above technical solution and has the following technical effects:

[0017] 1. When the present invention is feeding the animals, the PLC controller transmits a signal to the electric push rod, and the push rod end of the electric push rod extends. At this time, the cross plate pushes the first baffle and the push plate to move upward at the same time, so that the feed inside the storage tank enters the feeding trough through the discharge pipe. The weight sensor senses the weight change of the top feeding trough. When the weight reaches the weight that the animal needs to eat per meal, the push rod end of the electric push rod retracts, so that the first discharge hole and the second discharge hole are not located inside the discharge pipe, and the addition of feed to the feeding trough is stopped, thereby ensuring the accuracy of feed supply and making animal feeding more precise.

[0018] Second, when feeding the animal for the second time, the PLC controller outputs a signal to control the push rod end of the electric push rod to extend halfway, so that the second discharge hole is located inside the discharge pipe, and the residual feed inside the discharge pipe is preferentially discharged into the feeding trough. When the weight of the feed inside the feeding trough reaches the required weight, the first baffle blocks the discharge pipe, and the animal feed is added. The residual feed inside the discharge pipe is used for feeding first, avoiding feed waste and improving feed utilization. At the same time, the first baffle is close to one side of the feeding trough. After the first baffle is closed, the feed supply to the inside of the feeding trough can be quickly stopped, thereby improving the accuracy of feed supply.

[0019] 3. The reciprocating screw is driven to rotate by the output shaft end of the motor, and the reciprocating screw drives the threaded scraper to move toward one side of the through groove. Under the action of the sliding column, the scraper provides guidance. The scraper scrapes the feed remaining on the inner wall of the feeding trough to the inner side of the through groove, avoiding feed residue inside the feeding trough and ensuring the freshness of the feed.

[0035] The unloading assembly 2 includes an electric push rod 24 and a second baffle 211. A cross plate 23 is fixed to the push rod end of the electric push rod 24. A protrusion 21 is fixed to one side of the second baffle 211. The PLC controller 12 transmits a signal to the electric push rod 24. At this time, the push rod end of the electric push rod 24 extends, and the cross plate 23 pushes the first baffle 22 and the push plate 25 to move upward at the same time. The first baffle 22 and the push plate 25 are fixed to the top of the cross plate 23 respectively. A second discharge hole 213 is opened on one side of the first baffle 22. The outer side of the first baffle 22 is seamlessly inserted and slidably connected to one side of the discharge pipe 9. The bottom of the electric push rod 24 is fixed to the bottom of the inner wall of the fixed frame 10.

[0036] The first guide slope 26 is provided on one side of the top of the push plate 25, and the second guide slope 27 is provided on one side of the protrusion 21. The first discharge hole 212 is opened on one side of the second baffle 211. When the first baffle 22 is seamlessly inserted and slid inside the discharge pipe 9, the second discharge hole 213 enters the inside of the discharge pipe 9. At the same time, the first guide slope 26 on the top side of the push plate 25 slides on one side of the second guide slope 27, and the outer side of the second baffle 211 is seamlessly inserted and slides on one side of the discharge pipe 9. A limit block 29 is fixed on one side of the top of the second baffle 211, and a slide rod 210 is movably passed through one side of the limit block 29. A tension spring 28 is sleeved on the outer side of the slide rod 210. The two ends of the tension spring 28 are respectively connected to the limit block 29 and one side of the discharge pipe 9, so that the first discharge hole 212 and the second discharge hole 213 are not located inside the discharge pipe 9. At this time, the feeding trough 1 stops adding feed, and the weight of the feed is monitored by the weight sensor 7 to ensure the accuracy of feed supply.

[0037] The cleaning assembly 8 includes a box body 86, an inner wall of which is fixed with a motor 85, and a reciprocating screw 84 is fixed to the output shaft end of the motor 85. The PLC controller 12 outputs a signal to the motor 85, and the output shaft end of the motor 85 drives the reciprocating screw 84 to rotate. The reciprocating screw 84 drives the threaded scraper 81 to move toward the side of the through groove 83. The outer side of the reciprocating screw 84 is threaded with a scraper 81 that is slidably connected to the inner wall of the feeding trough 1. After scraping off the residual feed, the scraper 81 moves to a side close to the box body 86 under the power of the motor 85 for cleaning the inner wall of the feeding trough 1 next time. A sliding column 82 is fixed to the inner wall of the feeding trough 1, and the outer side of the sliding column 82 moves through one side of the scraper 81. A through groove 83 is provided on one side of the bottom of the feeding trough 1, and a sewage pipe is connected to the bottom of the through groove 83 to collect and discharge the residual feed.

[0038] A plurality of heat dissipation holes 87 are provided on one side of the box body 86. The box body 86 is fixed to one side of the feeding trough 1. A PLC controller 12 is installed on the inner wall of the fixing frame 10. A maintenance door 11 is connected to one side of the fixing frame 10 through a hinge. The output end of the weight sensor 7 is electrically connected to the input end of the PLC controller 12. The output end of the PLC controller 12 is electrically connected to the input end of the electric push rod 24 and the motor 85 respectively. The weight of the feed inside the feeding trough 1 is detected by the PLC controller 12, and the animals are fed at regular intervals and in fixed quantities, thereby achieving the purpose of precise feeding.

[0039] The model of the PLC controller 12 is: S7-1200;

[0040] The model of motor 85 is: ASF120A;

[0041] The model of the weight sensor 7 is: HX711.

[0042] Working principle: When it is necessary to feed the animals in the livestock industry, it is only necessary to add the required data of the electric push rod 24, the motor 85 and the weight sensor 7 into the PLC controller 12, and add a certain amount of feed into the storage tank 13 through the feeding port 14;

[0043] When the animal needs to be fed, the PLC controller 12 transmits a signal to the electric push rod 24, and the push rod end of the electric push rod 24 extends, causing the cross plate 23 to push the first baffle 22 and the push plate 25 to move upward at the same time. When the first baffle 22 is seamlessly inserted and slid inside the discharge pipe 9, the second discharge hole 213 enters the inside of the discharge pipe 9. At the same time, the first guide slope 26 on the top side of the push plate 25 slides on the side of the second guide slope 27, causing the second baffle 211 to move to the left under the thrust of the second guide slope 27, causing the tension spring 28 to stretch, causing the first discharge hole 212 to enter the inside of the discharge pipe 9;

[0044] At this time, the feed inside the storage tank 13 enters the feeding trough 1 through the discharge pipe 9, and the weight sensor 7 senses the weight change of the top feeding trough 1. When the weight inside the feeding trough 1 reaches the weight that the animal needs to eat per meal, the weight sensor 7 transmits a signal to the PLC controller 12. The PLC controller 12 controls the push rod end of the electric push rod 24 to retract, so that the first discharge hole 212 and the second discharge hole 213 are not located inside the discharge pipe 9. At this time, the addition of feed to the feeding trough 1 is stopped, and the weight of the feed is monitored by the weight sensor 7, which ensures the accuracy of the feed supply and makes the animal feed feeding more accurate.

[0045] When feeding the animals next time, the PLC controller 12 outputs a signal to control the push rod end of the electric push rod 24 to extend halfway. At this time, the second discharge hole 213 is located on the inner side of the discharge pipe 9, and the feed remaining in the discharge pipe 9 is preferentially discharged into the inner side of the feeding trough 1. When the weight of the feed inside the feeding trough 1 reaches the required weight, the PLC controller 12 controls the push rod end of the electric push rod 24 to retract, so that the first baffle 22 blocks the discharge pipe 9, and the feed addition to the animal is completed. The feed remaining in the discharge pipe 9 is preferentially used for feeding, avoiding feed waste and improving feed utilization. At the same time, the first baffle 22 is close to one side of the feeding trough 1. After the first baffle 22 is closed, the feed supply to the inside of the feeding trough 1 can be quickly stopped, thereby improving the accuracy of feed supply. When the feed amount is insufficient, the electric push rod 24 is fully extended, so that the feed inside the storage tank 13 continues to enter the inside of the feeding trough 1.

[0046] When the animal finishes eating, the PLC controller 12 outputs a signal to the motor 85. The output shaft end of the motor 85 drives the reciprocating screw 84 to rotate. The reciprocating screw 84 drives the threaded scraper 81 to move toward the side of the through groove 83. Under the action of the sliding column 82, the scraper 81 provides a guide. The scraper 81 scrapes the feed remaining on the inner wall of the feeding trough 1 to the inner side of the through groove 83, avoiding feed remaining inside the feeding trough 1 and ensuring the freshness of the feed.
