Description

Technical Field

[0001] This invention belongs to the field of pig farming technology, and relates to a feeding device and feeding method for pig farming. Background Technology

[0002] Pig farming refers to the complete process from breeding pigs to market-ready pigs, encompassing all stages from breeding pigs and piglet fattening to market-ready pigs. The pig farming industry occupies an important position in my country's agriculture.

[0003] Currently, most pig farming involves manually adding feed directly into the pig trough. However, this method has certain problems. First, the initial amount of feed added manually is limited and tends to be concentrated in one place, causing the pigs to rush in, resulting in competition and trampling among them. Only by continuing to add feed can the pigs disperse as more feed is added.

[0004] Meanwhile, the existing pig feed trough is a straight groove, and the pig feed is flowing. Strong pigs eat faster and will compete for the feed of other pigs, which can easily lead to uneven feeding and uneven growth of pigs.

[0005] To address the aforementioned problems, an improved feeding device and feeding method for pig farming are now designed. Summary of the Invention

[0006] Purpose of the invention: The purpose of this invention is to address the problems of competition and trampling, uneven feeding, and feed residue in pig herds by providing a feeding device and method for pig farming.

[0007] Technical solution: The present invention provides a feeding device for pig farming, comprising a feeding trough, a storage frame, and a feeding frame. The storage frame is used to store feed, and the feeding frame is disposed on one side of the feeding trough. The feeding frame has an opening at the lower end of the side wall near the feeding trough, and the bottom of the feeding frame is configured as an inclined plate facing the opening for introducing feed into the feeding trough. The device also includes a feeding mechanism, a feeding component, a collecting mechanism, and a controller.

[0008] The feeding mechanism is located inside the feeding frame. The feeding mechanism includes a swing plate and a second electric telescopic rod for driving the swing plate to swing. The upper end of the swing plate is rotatably connected to the inner wall of the feeding frame, and the lower end of the swing plate is a free end. When the swing plate swings, it feeds the received feed into the feeding trough through the opening of the feeding frame.

[0009] The feeding assembly is connected between the outlet of the storage frame and the feeding frame, and is used to transport feed from the storage frame to the inside of the feeding frame. The feeding assembly includes an outlet pipe, a feeding pipe, and a second electrically controlled valve. The outlet pipe is vertically installed at the outlet of the storage frame, and the feeding pipe is connected to the outlet pipe. The feeding pipe includes a first outlet and a second outlet. The first outlet is connected to a discharge pipe, and the second outlet is connected to a conveying main pipe. The discharge end of the discharge pipe is located above the swing plate and is used to convey the initial feed to the swing plate. The discharge end of the conveying main pipe extends above the feeding trough and is used to replenish feed into the feeding trough. The second electrically controlled valve is located at the first outlet of the feeding pipe, and the controller controls the second electrically controlled valve to realize the opening and closing of the discharge pipe.

[0010] The collecting mechanism is disposed on the storage frame. The collecting mechanism includes a scraper and a reciprocating drive mechanism for driving the scraper to move back and forth along the inner wall of the storage frame. The side wall of the scraper is in close contact with the inner wall of the storage frame and is used to collect the feed remaining on the inner wall of the storage frame towards the discharge port.

[0011] Furthermore, the inner wall of the feeding frame is also provided with a first identification strip and a third camera. The third camera is located on the inner wall of the feeding frame opposite to the first identification strip. The third camera is used to detect whether the feed on the swing plate covers the first identification strip, and accordingly sends a signal to the controller to control the opening and closing of the second electrically controlled valve.

[0012] Furthermore, a vibrator is installed on the swing plate, which is used to assist the feed to slide off when the swing plate swings.

[0013] Furthermore, the feeding assembly also includes several distribution pipes, each of which is connected to the main conveying pipe and is arranged at intervals along the length of the feeding trough. Each distribution pipe is equipped with a first electrically controlled valve.

[0014] Furthermore, the feeding trough is also provided with a dividing mechanism, which includes several partitions and a moving frame for driving all the partitions to rise and fall synchronously. After the partitions move downward, they are inserted into the feeding trough, dividing the feeding trough into several independent compartments along the length direction. The discharge end of each of the feed distribution pipes corresponds one-to-one with each of the independent compartments.

[0015] Furthermore, a second groove is provided at the lower end of the partition, which is used to engage with the top of the side wall of the feeding trough when the partition is lowered.

[0016] Furthermore, it also includes several second cameras, each corresponding to one of the independent compartments. The second cameras are used to capture images of the pigs' body shape in the corresponding compartment and transmit them to the controller. The controller controls the opening duration of each of the first electrically controlled valves according to the body shape images, so as to supplement different amounts of feed into the corresponding compartments.

[0017] Furthermore, the reciprocating drive mechanism includes a fixed frame, a bidirectional lead screw, and a motor for driving the bidirectional lead screw to rotate. The bidirectional lead screw is disposed inside the fixed frame, and internal threaded sleeves are rotatably connected to the two opposite threads of the bidirectional lead screw. The scraper is mounted on the internal threaded sleeves via a connecting rod. The storage frame is also provided with a first camera and a second identification strip. The second identification strip is installed on the inner wall of the storage frame away from the fixed frame. The first camera is disposed on the upper end of the side wall of the storage frame opposite to the second identification strip via a second bracket. When the first camera detects that the second identification strip is exposed, it sends a signal to the controller to start the motor.

[0018] Furthermore, the discharge port of the storage frame is located at the center of the bottom of the storage frame, and the bottom of the storage frame is provided with an inclined block that slopes toward the discharge port.

[0019] Another object of the present invention is to provide an intelligent feeding method for pig farming, which uses the above-mentioned feeding device for pig farming and includes the following steps:

[0020] Step 1: The initial feed is quantitatively delivered to the swing plate through the feed pipe of the feeding component. When the amount of feed reaches the preset value, the swing plate is driven to swing downward, so that the initial feed is evenly distributed into the feeding trough.

[0021] Step 2: Activate the partitioning mechanism to divide the feeding trough into several independent compartments, so that each pig occupies its own compartment;

[0022] Step 3: The second camera collects the body size information of the pigs in each compartment. The controller controls the opening duration of each first electrically controlled valve according to the body size information, and supplements different amounts of feed to the corresponding compartment through the feed pipe to achieve differentiated feeding.

[0023] Step 4: When the feed in the storage box is lower than the preset level, start the collection mechanism and scrape the feed remaining on the inner wall of the storage box towards the discharge port using the scraper.

[0024] Beneficial effects: (1) The present invention first delivers the feed to the swing plate, disperses the feed evenly through the swing plate, and then delivers the feed together into the trough through the opening, thus avoiding the situation where pigs fight and trample each other due to uneven initial feed delivery.

[0025] (2) After the pigs have been feeding in a stable and dispersed manner, the partition is lowered to separate the pigs and the feeding troughs. Then, the size of the pigs in the compartment is observed through the second camera, and feed is added to the feeding troughs in the corresponding compartments so that each pig can be fed to its heart's content, while avoiding feed waste.

[0026] (3) The present invention moves the two scraper plates relative to each other by means of a two-way screw, so that the scraper plates collect the feed inside the storage box to the input end of the discharge pipe, so that the discharge pipe can continuously transport feed and avoid feed waste.

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0033] Please see Figures 1-4In this embodiment of the invention, a feeding device for pig farming includes a feeding trough 1. A feeding frame 6 is installed on the upper end of one side wall of the feeding trough 1. A first support 4 for supporting the feeding frame 6 is installed on the lower end of the feeding frame 6. An opening 3 is provided on the lower end of the side wall of the feeding frame 6 near the feeding trough 1. The bottom of the feeding frame 6 is configured as an inclined plate to facilitate the conveying of feed into the feeding trough 1 through the opening 3. A storage frame 7 for storing feed is installed on the upper end of the feeding frame 6. A controller 32 is installed on the side wall of the feeding frame 6 away from the feeding trough 1. A discharge pipe 30 is vertically installed at the center of the bottom of the storage frame 7. The lower end of the discharge pipe 30... A feeding pipe 9 is horizontally installed through the bottom of the storage frame 7. The feeding pipe 9 is located inside the feeding frame 6. The feeding pipe 9 is perpendicular to the side wall of the feeding frame 6 where the opening 3 is located. An inclined block 28 is installed at the bottom of the storage frame 7 to collect feed to the center of the bottom of the storage frame 7. A fixing frame 16 is installed at the upper end of the side wall of the storage frame 7 near the feeding trough 1. The inside of the feeding frame 6 is provided with a feeding mechanism to evenly add feed into the feeding trough 1 during initial feeding. The feeding trough 1 is provided with a separating mechanism to separate each pig. The storage frame 7 is provided with a collecting mechanism to collect feed to the center of the storage frame 7.

[0034] The feeding mechanism includes a swing plate 31, which is inclinedly disposed inside the feeding frame 6 below the feeding pipe 9. The upper end of the swing plate 31 is rotatably connected to the inner wall of the feeding frame 6 above the opening 3, and the lower end of the swing plate 31 is inclined away from the opening 3. Several second electric telescopic rods 24 for driving the swing plate 31 to swing are rotatably connected to the inner wall of the feeding frame 6 between the swing plate 31 and the opening 3. The output end of the second electric telescopic rod 24 is rotatably connected to the side wall of the swing plate 31 near the opening 3 via a hinge. A vibrator 23 for vibrating the swing plate 31 is installed on the side wall of the swing plate 31 near the opening 3. The side wall of the swing plate 31 is sealed tightly to the inner wall of the feeding frame 6 by a sealing gasket. A feeding assembly for adding feed to the swing plate 31 and detecting the amount added is provided above the swing plate 31.

[0035] The feeding assembly includes a feed pipe 26 for feeding feed to the upper end of the swing plate 31. The input end of the feed pipe 26 is installed at the end of the feed pipe 9 away from the feed trough 1. A second electrically controlled valve 27 for controlling the feed pipe 9 to feed feed to the feed pipe 26 is installed on the feed pipe 9 between the feed pipe 26 and the discharge pipe 30. A first identification strip 25 is installed on the inner wall of the feeding frame 6 between the feed pipe 26 and the swing plate 31. The first identification strip 25 is installed on the inner wall of the feeding frame 6 away from the opening 3. A third camera 33 is installed on the inner wall of the feeding frame 6 above the swing plate 31, which works in conjunction with the first identification strip 25 to detect the amount of feed added. The third camera 33 is installed on the inner wall of the feeding frame 6 where the opening 3 is located.

[0036] In use, the second electrically controlled valve 27 is opened, allowing the feed inside the storage box 7 to be added to the upper end of the swing plate 31 through the discharge pipe 30, the feeding pipe 9, and the discharge pipe 26. When the feed is higher than the first indicator bar 25, the third camera 33 cannot capture the first indicator bar 25. The third camera 33 sends a signal to the controller 32, which controls the second electrically controlled valve 27 to close and controls the second electric telescopic rod 24 to retract. Under the action of the hinge, the second electric telescopic rod 24 drives the swing plate 31 to swing downward. The feed on the swing plate 31 flows to the bottom of the feeding box 6 and then flows through the opening 3 into the feed trough 1. After the feed on the swing plate 31 is discharged, the swing plate 31 is reset.

[0037] The separating mechanism includes several partitions 21, which are vertically arranged above the feeding trough 1. The lower end of each partition 21 has a second groove 22 to facilitate insertion of the partition 21 into the feeding trough 1. After the partition 21 is inserted downward into the feeding trough 1, it divides the feeding trough 1 into several compartments, each compartment accommodating only one pig. The upper end of each partition 21 has a first groove 2 on the side near the feeding frame 6. The upper end of each partition 21 is equipped with a moving frame 20 for moving all the partitions 21 up and down. Both ends of the feeding frame 6 are vertically equipped with first electric telescopic rods 5. The output end of the first electric telescopic rods 5 is installed at the lower end of the moving frame 20. The feeding frame 6 is equipped with a feeding component for supplementing feed into the feeding trough 1 of the compartment according to the size of the pig in the compartment.

[0038] The feeding assembly includes several second cameras 17, each corresponding to a compartment separated from the feeding trough 1. The second cameras 17 are mounted on the side wall of the fixed frame 16 away from the storage frame 7. The end of the feeding pipe 9 near the feeding trough 1 is horizontally installed with a conveying main pipe 10 through the side wall of the feeding frame 6. The conveying main pipe 10 is located directly above the first groove 2. Several distributing pipes 18 corresponding to compartments separated from the feeding trough 1 are vertically installed at the lower end of the conveying main pipe 10. The lower end of the distributing pipe 18 is located at the upper end of the opening 3. A first electrically controlled valve 19 for controlling the opening and closing of the distributing pipe 18 is provided on the side wall of the distributing pipe 18 near the conveying main pipe 10. The conveying main pipe 10, the distributing pipes 18, and the first electrically controlled valve 19 are arranged between the movable frame 20 and the feeding frame 6.

[0039] After the oscillating plate 31 adds feed into the trough 1, the first electric telescopic rod 5 is activated to retract. The output end of the first electric telescopic rod 5 drives the moving frame 20 to move downward. The moving frame 20 drives the partition 21 to move downward. The second groove 22 at the lower end of the partition 21 fits onto the side wall of the trough 1, thereby dividing the trough 1 into several compartments, with only one pig in each compartment. Then, the second camera 17 captures the body shape of the pig in each compartment and transmits the image data to the controller 32. The controller 32 controls the first electrically controlled valve 19 on the corresponding compartment to open and controls the opening time, thereby replenishing the feed in the corresponding compartment.

[0040] The collecting mechanism includes a bidirectional lead screw 34, which is disposed inside the fixed frame 16. The two ends of the rotating shaft of the bidirectional lead screw 34 are rotatably connected to the inner wall of the fixed frame 16. One end of the rotating shaft of the bidirectional lead screw 34 passes through the side wall of the fixed frame 16 and is equipped with a motor 8 for driving the bidirectional lead screw 34 to rotate. The motor 8 is mounted on the side wall of the fixed frame 16. Internal threaded sleeves 15 are rotatably connected to the two opposite threads of the bidirectional lead screw 34. The internal threaded sleeves 15 move along the inner wall of the fixed frame 16. A connecting rod 14 is installed at the upper end of the internal threaded sleeve 15. A scraper plate 13 for scraping the inner wall of the storage frame 7 is installed at the end of the connecting rod 14 away from the internal threaded sleeve 15. The side wall of the scraper plate 13 is in close contact with the inner wall of the storage frame 7. A control component for controlling the motor 8 is provided on the storage frame 7.

[0041] The control component includes a second identification strip 29, which is installed on the inner wall of the storage frame 7 away from the fixed frame 16. A second bracket 12 is installed at the center of the upper end of the side wall of the storage frame 7 near the fixed frame 16. A first camera 11 that works in conjunction with the second identification strip 29 is installed on the top of the second bracket 12.

[0042] When the first camera 11 captures the second identification strip 29, the first camera 11 sends a signal to the controller 32. The controller 32 controls the motor 8 to start. The output end of the motor 8 drives the bidirectional lead screw 34 to rotate. Under the action of the thread, the bidirectional lead screw 34 drives the two internal thread sleeves 15 to move towards the center position of the fixed frame 16. The internal thread sleeves 15 drive the connecting rod 14 to move. The connecting rod 14 drives the scraper 13 to move. The scraper 13 collects the feed remaining inside the storage box 7 to the input end of the discharge pipe 30.

[0043] This embodiment provides an intelligent feeding method for pig farming, including the following steps:

[0044] Step 1: The initial feed is quantitatively fed onto the swing plate 31 through the feed pipe 26 of the feeding component. When the amount of feed reaches the preset value, the swing plate 31 is driven to swing downward, so that the initial feed is evenly distributed and falls into the feeding trough.

[0045] Specifically, the staff adds feed into the storage box 7, and then the controller 32 first controls the second electric valve 27 to open, so that the feed in the storage box 7 is added to the upper end of the swing plate 31 through the discharge pipe 30, the feeding pipe 9, and the discharge pipe 26. When the feed is higher than the first indicator bar 25, the third camera 33 cannot capture the first indicator bar 25. The third camera 33 sends a signal to the controller 32, and the controller 32 controls the second electric valve 27 to close and controls the second electric telescopic rod 24 to retract. Under the action of the hinge, the second electric telescopic rod 24 drives the swing plate 31 to swing downward. The feed on the swing plate 31 flows to the bottom of the feeding box 6, and then flows through the opening 3 into the feed trough 1. After the feed on the swing plate 31 is discharged, the swing plate 31 is reset.

[0046] Step 2: Activate the partitioning mechanism to divide trough 1 into several independent compartments, so that each pig has its own compartment;

[0047] Step 3: The second camera 17 collects the body size information of the pigs in each compartment. The controller 32 controls the opening duration of each first electronically controlled valve 19 according to the body size information, and supplements different amounts of feed to the corresponding compartment through the feed distribution pipe 18 to achieve differentiated feeding.

[0048] Specifically, the first electric telescopic rod 5 is activated to retract, and the output end of the first electric telescopic rod 5 drives the moving frame 20 to move downward. The moving frame 20 drives the partition 21 to move downward. The second groove 22 at the lower end of the partition 21 fits onto the side wall of the feeding trough 1, thereby dividing the feeding trough 1 into several compartments, with only one pig in each compartment. Then, the second camera 17 captures the body shape of the pig in each compartment and transmits the image data to the controller 32. The controller 32 controls the first electrically controlled valve 19 on the corresponding compartment to open and controls the opening time, thereby enabling the feeding trough 1 in the corresponding compartment to be replenished.

[0049] Step 4: When the feed in the storage box 7 is lower than the preset reserve, start the collection mechanism and scrape the feed remaining on the inner wall of the storage box 7 towards the discharge port through the scraper 13.

[0050] Specifically, when the first camera 11 captures the second identification strip 29, the first camera 11 sends a signal to the controller 32, and the controller 32 controls the motor 8 to start. The output end of the motor 8 drives the bidirectional lead screw 34 to rotate. Under the action of the thread, the bidirectional lead screw 34 drives the two internal thread sleeves 15 to move towards the center position of the fixed frame 16. The internal thread sleeves 15 drive the connecting rod 14 to move. The connecting rod 14 drives the scraper 13 to move. The scraper 13 collects the feed remaining inside the storage frame 7 to the input end of the discharge pipe 30.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
