Description

Technical Field

[0001] This utility model relates to the field of pig breeding technology, specifically a directional feeding machine for pigs. Background Technology

[0002] Pigs, also known as shi or tun, are the most commonly consumed meat due to their ease of raising and their characteristics of fine bones, few tendons, and abundant meat. However, physicians throughout history have believed that: "Pigs are the most commonly used meat, but their meat should not be eaten in excess, as it causes rapid weight gain due to weak muscles." "All meats are nourishing, except pork." "Using meat to nourish yin is like using fire to balance water, because meat, once it enters the stomach, becomes damp and hot, generating phlegm. When phlegm is generated, qi cannot descend, and various symptoms arise." Therefore, eating too much pork is not beneficial for patients with yin deficiency or blood deficiency. Due to huge market demand, the number of pig farmers is increasing daily, and feeding pigs is an essential daily task.

[0003] Currently, most pig farming methods rely on manual feeding in pig troughs. Pigs eat quickly, requiring frequent refeeding, which consumes significant manpower and resources. Furthermore, refeeding can cause feed to accumulate, leading to pigs crowding into one spot and potentially fighting over food, thus affecting their health. To address this, we have proposed a directional feeding machine for pigs. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1 to 7A directional feeding machine for pigs includes a device body 1. A storage container 2 for storing pig feed is installed on the outside of the device body 1. A through groove 3 is opened inside the device body 1. A fixed frame 5 is installed inside the through groove 3. The storage container 2 can store feed. When the feed is insufficient, the stored feed can be supplemented to the top of the moving plate 11 through the discharge port 14.

[0035] The fixed frame 5 has a through hole 10. A lifting device 102 that can move up and down according to the amount of feed is installed at the bottom of the through hole 10. When the feed on the top of the moving plate 11 is insufficient, the lifting device 102 can drive the switch trigger component to move upward. When the feed on the moving plate 11 is replenished, the lifting device 102 can drive the switch trigger component to move downward to restore the initial state.

[0036] The feed storage device 2 is externally equipped with a discharge port 14 that allows pig feed to flow into the fixed frames 5. A feed switch device 101 is installed on the discharge port 14. The feed switch device 101 includes a trigger rod 13, a sliding structure, and an opening / closing structure. The opening / closing structure is installed inside the discharge port 14. A sliding frame 15 is installed outside the discharge port 14. The sliding structure is installed inside the sliding frame 15 and can slide up and down. The opening / closing structure passes through the discharge port 14 and connects to the sliding structure. The trigger rod 13 is installed outside the sliding structure. The lifting device 102... During the movement, the device can contact the trigger rod 13 and push the sliding structure upward, driving the opening and closing structure to open to replenish pig feed. When the feed above the moving plate 11 is insufficient, the lifting device 102 will drive the switch trigger component to move upward and contact the trigger rod 13. The trigger rod 13 can drive the sliding structure to move upward in the sliding frame 15 and drive the opening and closing structure to open so that the feed flows to the top of the moving plate 11 to replenish the feed. When the feed is replenished, the lifting device 102 will drive the switch trigger component to move downward, and the first spring 17 will rebound to close the opening and closing structure, thereby stopping the replenishment of feed.

[0037] The bottom of the lifting device 102 is equipped with an anti-stacking device 103 that can knock on the lifting device 102 to prevent the pig feed from piling up. The anti-stacking device 103 can knock on the moving plate 11 at a high frequency, thereby shaking the feed above the moving plate 11 and making it less likely to pile up.

[0038] Please see Figures 1 to 5 The sliding structure includes a sliding plate 16.

[0039] The sliding frame 15 has a sliding groove inside, and the sliding plate 16 is slidably connected to the sliding groove. A first spring 17 is fixedly connected to the bottom of the sliding plate 16. The first spring 17 is fixedly connected to the bottom of the sliding groove of the sliding frame 15. The sliding plate 16 has an upward-opening concave structure. Grooves are opened through the inner walls on both sides of the concave opening of the sliding plate 16. When the feed at the top of the moving plate 11 is insufficient, the motor drive assembly will drive the switch trigger assembly to move upward and contact the trigger rod 13. The trigger rod 13 drives the sliding plate 16 to slide in the sliding groove, thereby driving the opening and closing structure to open. The feed flows into the upper part of the moving plate 11 through the discharge port 14 to replenish the feed.

[0040] Please see Figures 1 to 5 The opening and closing structure includes a first circular sliding block 18, a second circular sliding block 20, a first cylindrical connecting rod 22, a second cylindrical connecting rod 23, a first semi-circular opening and closing block 24, and a second semi-circular opening and closing block 25.

[0041] A first cylindrical connecting rod 22 is rotatably connected inside the discharge port 14. A second cylindrical connecting rod 23 is sleeved on the outside of the first cylindrical connecting rod 22. The second cylindrical connecting rod 23 is rotatably connected to the inside of the discharge port 14. A first semi-circular opening and closing block 24 is installed on the outside of the first cylindrical connecting rod 22. A second semi-circular opening and closing block 25 is installed on the outside of the second cylindrical connecting rod 23. A second circular sliding block 20 is installed on the outside of the second cylindrical connecting rod 23, passing through the discharge port 14. An off-center second circular limiting block 21 is installed on one end of the second circular sliding block 20 near the sliding plate 16. The second circular limiting block 21 is slidably connected in the groove. A first circular sliding block 18 is installed on the outside of the first cylindrical connecting rod 22, passing through the discharge port 14 and the second circular sliding block 20. The first circular sliding block 18 is close to the second circular sliding block 16. One end of the sliding block 20 is equipped with an off-center first circular limiting block 19, which is slidably connected in the groove. The first circular limiting block 19 and the second circular limiting block 21 are distributed on both sides of the groove. When the feed at the top of the moving plate 11 is insufficient, the motor drive assembly will drive the switch trigger assembly to move upward and drive the sliding structure to slide upward in the sliding frame 15. While sliding, it will push the first circular limiting block 19 and the second circular limiting block 21, thereby driving the first circular sliding block 18 and the second circular sliding block 20 to rotate. The rotation of the first circular sliding block 18 and the second circular sliding block 20 will drive the first cylindrical connecting rod 22 and the second cylindrical connecting rod 23 to rotate, thereby driving the first semi-circular opening and closing block 24 and the second semi-circular opening and closing block 25 to open. The feed flows to the top of the moving plate 11 through the discharge port 14, thereby completing the replenishment of feed.

[0042] Please see Figures 1 to 2Multiple limiting grooves are provided on both sides of the through groove 3. A fixing rod 4 is installed on the outside of the limiting groove. The fixing rod 4 is fixedly connected to the fixing frame 5. The fixing frame 5 is installed on the through groove 3 through the fixing rod 4 and is fixed in place. The lifting device 102 will drive the moving plate 11 to move up and down in the fixing frame 5 according to the amount of feed on the top of the moving plate 11. In this way, the pigs do not need to stretch their necks when eating, reducing the occurrence of diseases.

[0043] Please see Figures 1 to 3 The lifting device 102 includes a motor drive assembly and a switch trigger assembly. The switch trigger assembly is slidably connected to the bottom of the through hole 10, and the top surface of the switch trigger assembly abuts against the inner wall of the fixed frame 5. The motor drive assembly is installed at the bottom of the through groove 3, and the motor drive assembly and the switch trigger assembly are threadedly connected. The motor drive assembly can drive the switch trigger assembly to slide up and down according to the amount of pig feed on the top surface of the switch trigger assembly. The motor drive assembly can drive the switch trigger assembly to slide up and down within the fixed frame 5 according to the amount of feed on the top of the moving plate 11. While sliding, the switch trigger assembly can contact the trigger rod 13, thereby driving the sliding structure to slide open the opening and closing structure to replenish feed.

[0044] Please see Figures 1 to 3 The switch triggering component includes a movable plate 11 and a trigger block 12;

[0045] The movable plate 11 is slidably connected to the bottom of the through hole 10. The top surface of the movable plate 11 abuts against the inner wall of the fixed frame 5. A trigger block 12 is installed at the bottom of the movable plate 11 near the feeder 2. The trigger block 12 can contact the trigger rod 13. A first protective shell 9 is installed on the top of the movable plate 11. Depending on the amount of feed on the top of the movable plate 11, the motor drive assembly can drive the movable plate 11 to move upward. When the movable plate 11 moves upward, it will drive the trigger block 12 to move upward synchronously. The trigger block 12 can contact the trigger rod 13, thereby driving the sliding structure to slide open the opening and closing structure to replenish feed.

[0046] Please see Figures 1 to 2 The motor drive assembly includes a motor 6, a gear 7, and a threaded rod 8;

[0047] A motor 6 is installed at the bottom of the through groove 3, corresponding to the position of the first protective shell 9. The output shaft end of the motor 6 is connected to a gear 7. A threaded rod 8 is installed on the top of the gear 7. The threaded rod 8 passes through the moving plate 11 and reaches the interior of the first protective shell 9. The threaded rod 8 is threadedly connected to the moving plate 11. When the feed on the top of the moving plate 11 decreases, the motor 6 will automatically start, driving the gear 7 to rotate. The gear 7 will drive the threaded rod 8 to rotate. The threaded rod 8 will drive the moving plate 11 to slide upward within the fixed frame 5. When the feed is replenished, the motor 6 will drive the gear 7 to rotate in the opposite direction, thereby driving the threaded rod 8 to rotate in the opposite direction. The threaded rod 8 will drive the moving plate 11 to move downward, returning to the initial state.

[0048] Please see Figures 1 to 7 The anti-accumulation device 103 includes a square plate 26, a connecting block 27, a connecting rod 28, a cylindrical rod 29, a second spring 30, a square frame 31, and a disc limiter 32.

[0049] A second protective shell 33 is installed at the bottom of the movable plate 11. A slot is formed inside the second protective shell 33, and a square frame 31 is installed at the top of the slot. The square frame 31 is hollow, and a second spring 30 is fixedly connected inside the square frame 31. The second spring 30 is fixedly connected to the bottom of the disc limiter 32. A cylindrical rod 29 is installed at the center of the bottom of the disc limiter 32. The cylindrical rod 29 passes through the square frame 31 and is hinged to a connecting rod 28. A square plate 26 is installed on one side of the bottom of the square frame 31, and a motor 34 is installed on the outside of the square plate 26. The output shaft passes through the square plate 26 and is connected to one end of the connecting block 27. The other end of the connecting block 27 is rotatably connected to the connecting rod 28. The size of the disc limiter 32 is adapted to the size of the inner wall of the square frame 31. When the discharge port 14 replenishes feed to the top of the moving plate 11, the motor 34 starts and drives the connecting block 27 to drive the connecting rod 28 to rotate off-center. The connecting rod 28 drives the cylindrical rod 29 to continuously knock on the bottom of the moving plate 11 under the elastic force of the second spring 30, so that the feed above the moving plate 11 vibrates and disperses, and does not pile up. When the feed is replenished, the motor 34 is turned off and stops rotating.

[0050] In summary, when the directional feeder for pigs is in use, the motor 6 starts according to the amount of feed as the pigs continuously feed on the top of the moving plate 11, driving the gear 7 to rotate. Simultaneously, the gear 7 rotates, causing the threaded rod 8 to rotate synchronously, and the moving plate 11 to slide upwards within the fixed frame 5. Pigs do not need to stretch their necks to feed. As the moving plate 11 slides, the trigger block 12 slides upwards synchronously, and can contact the trigger rod 13, pushing the trigger rod 13 upwards. The trigger rod 13 then drives the sliding plate 16 to slide upwards, stretching the first spring 17. As the sliding plate 16 moves upwards, it also affects the first circular limiter. The first circular limiting block 19 and the second circular limiting block 21 are pushed, and the first circular limiting block 19 and the second circular limiting block 21 synchronously drive the first circular sliding block 18 and the second circular sliding block 20 to rotate off-center in the same direction. The first circular sliding block 18 and the second circular sliding block 20 drive the first cylindrical connecting rod 22 and the second cylindrical connecting rod 23 to rotate. The first cylindrical connecting rod 22 and the second cylindrical connecting rod 23 drive the first semi-circular opening and closing block 24 and the second semi-circular opening and closing block 25 to rotate in the same direction. In this way, the feed can flow through the discharge port 14 to the top of the moving plate 11. At the same time as the feed is replenished, the motor 34 drives the connecting block 27 to rotate. When the connecting block 27 moves, it drives the connecting rod 28 to rotate off-center. The connecting rod 28 drives the cylindrical rod 29 to continuously strike the moving plate 11, thereby causing the moving plate 11 to shake continuously. This causes the feed flowing into the top of the moving plate 11 to be shaken, spread evenly, and not piled up. This prevents pigs from crowding in one direction while feeding, reducing the chance of fighting among pigs. When the feed is replenished, the motor 6 drives the gear 7 to rotate in the opposite direction. The gear 7 drives the threaded rod 8 to rotate in the opposite direction simultaneously. The threaded rod 8 drives the moving plate 11 to move downward. At the same time, the trigger block 12 disengages from the trigger rod 13. At this time, the squeezing force on the first spring 17 disappears. Spring 17 quickly rebounds to return to its initial state, causing sliding plate 16 to move downwards and return to its initial state. As sliding plate 16 moves downwards, first circular limit block 19 and second circular limit block 21 return to their initial states. First circular sliding block 18 and second circular sliding block 20 drive first cylindrical connecting rod 22 and second cylindrical connecting rod 23 to rotate. First cylindrical connecting rod 22 and second cylindrical connecting rod 23 drive first semi-circular opening and closing block 24 and second semi-circular opening and closing block 25 to close. This completes the automatic replenishment of feed when it is insufficient and the automatic closing when the feed is replenished, eliminating the need for multiple replenishments by personnel and saving manpower and resources.
