Description

Technical Field

[0001] The invention relates to the technical field of feed feeding, in particular to an automatic feeding and discharging device for pig feed. Background Art

[0002] Existing pig feed feeding devices usually use solenoid valves and spiral conveying structures to time the feed falling time to achieve the function of automatic feeding, but this feeding method is limited by the physical properties of the feed. For example, when using paste feed, when the viscosity of the paste feed changes, its flow characteristics will change significantly. When the viscosity increases, its fluidity becomes worse, and the speed of passing through the solenoid valve will slow down. For example, in a cold environment, the water in the paste feed may partially freeze or components such as starch may precipitate, resulting in a significant increase in viscosity. At this time, even if the solenoid valve is opened at the set time, the amount of feed passing through the solenoid valve will decrease, because its flow rate in the same time is slowed down and cannot reach the set required weight, which will cause the actual feed feeding amount to be inaccurate, so that the pigs cannot obtain enough nutrients.

[0003] To this end, the present invention provides an automatic feeding and discharging device for pig feed. Summary of the invention

[0006] The top surface of the carrier plate is fixedly connected with a horizontal slide, and two limit slides are slidably connected to the bottom surface of the carrier plate, and the bottom surface of the carrier plate is fixedly connected with two horizontal slides, and the bottom surface of the carrier plate is fixedly connected with two horizontal slides, and the bottom surface of the carrier plate is fixedly connected with two horizontal slides, and the bottom surface of the carrier plate is fixedly connected with two horizontal slides, and the bottom surface of the carrier plate is fixedly connected with four bottom rods in a rectangular array, and the bottom ends of the four bottom rods are rotatably connected with a rotating shaft, and the four rotating shafts are respectively provided with a sealing belt, and the four rotating shafts are respectively provided with a clockwork spring.

[0007] Furthermore, the top end of the support rod extends to the top of the feeding trough frame.

[0008] Furthermore, the silo and the rotating plate in the middle are located in the same vertical plane, the rotating plate is embedded in the silo, the upper surface of the rotating plate and the upper surface of the silo are in the same horizontal plane, and the threaded rod passes through the carrier plate and is fixedly connected to the rotating plate.

[0009] Furthermore, the threaded rod is threadably connected to the thread groove, and the weighing sensor, the bottom spring and the stop column are all sleeved on the threaded rod located in the middle.

[0010] Furthermore, one end of the bottom spring away from the weighing sensor is fixedly connected to the lower surface of the carrier plate, and the weighing sensor and the plurality of solenoid valves are electrically connected via a controller.

[0011] Furthermore, the two inclined slides are arranged in an inclined shape, and the two vertical slides extend away from one end of the corresponding multi-section hollow telescopic plate to a side close to the support rod.

[0012] Furthermore, the end of the transverse slideway away from the carrier plate extends to the outer wall of the feeding trough frame close to the support rod, and the two limit sliding posts slide on the corresponding vertical slideway and inclined slideway respectively.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The feed on the top of the carrier is the feed weight required by the breeder. Compared with the existing method of relying solely on the solenoid valve to control the feed falling time, this method is not affected by changes in the physical properties of the feed. It can ensure that the pigs can get the correct amount of feed each time they are fed, which is conducive to accurate nutrition supply and meets the needs of pigs at different growth stages and health conditions;

[0016] When the carrier plate moves, it can drive the rotating plate to rotate, so that the paste feed on the top of the carrier plate is driven to mix and stir, avoiding the sedimentation and stratification of the paste feed when it is stored in the silo. The rotation of the rotating plate drives the mixing, which can break the stratified structure and make the feed components evenly distributed in the vertical direction, ensuring the uniformity of feed mixing as much as possible, ensuring that the pigs can take in balanced nutrition every time they eat, and avoiding the growth affected by excessive or low local nutrients;

[0017] The feed on the top of the carrier plate is consumed by the pigs, and the pressure on the carrier plate is reduced. Under the elastic extension of the bottom spring, the carrier plate moves upward inside the feeding trough frame, and the threaded rod moves upward inside the threaded groove, so that the threaded rod rotates in the opposite direction, which can achieve continuous mixing of feed while the pigs consume the feed, and can effectively prevent the paste feed from drying and sticking on the carrier plate and the feeding trough frame, which is conducive to the smooth feeding of pigs;

[0018] The effective feed volume on the top of the carrier plate can change with the weight of the feed. This adaptive volume change can effectively prevent the feed from overflowing due to insufficient volume. At the same time, the adaptive volume can provide appropriate feeding space according to the amount of feed. When the amount of feed is large, pigs can easily feed in a spacious space without having to look for food in a crowded environment. When the amount of feed is small, the reduced space allows pigs to obtain food more concentratedly, reducing the time and energy consumption of looking for food and improving feeding efficiency.

[0019] The two multi-section hollow telescopic plates move towards each other to push the feed toward the center of the carrier plate, so that the space occupied by the paste feed on the carrier plate is reduced, which can effectively reduce the contact area between the paste feed and the air, reduce the oxidation rate of the paste feed, and thus maintain the freshness and nutritional value of the paste feed;

[0020] The remaining paste feed is concentrated in the central area of ​​the carrier plate by the inward contraction of two multi-section hollow telescopic plates, and the lifting of the carrier plate makes the pig's feeding area shallower, making it easier for the pig to find and obtain food. This is especially important for piglets or weaker pigs, as they do not need to spend too much energy looking for small amounts of food scattered in a large area of ​​the trough when feeding, thereby improving feeding efficiency.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiments provided by the present invention:

[0037] Embodiment 1:

[0038] See also Figures 1 to 5 As shown, an automatic feeding and discharging device for pig feed includes a quantitative feeding component, which includes a feeding trough frame 11 and four legs 12, the four legs 12 are fixedly connected to the bottom surface of the feeding trough frame 11, the bottom of the outer wall of the feeding trough frame 11 is fixedly connected with a support rod 13, the top of the support rod 13 extends to the top of the feeding trough frame 11, the top of the support rod 13 is fixedly connected with a silo 14, the top of the silo 14 is clamped with a feed cover 15, the bottom of the silo 14 is provided with a plurality of discharging pipes, and the silo 14 has a plurality of discharging pipes. A solenoid valve 17 is installed at the bottom end of each tube, the inner wall of the feeding trough frame 11 is slidably connected with a carrier plate 18, the top surface of the carrier plate 18 is rotatably connected with multiple rotating plates 19, the bottom surfaces of the multiple rotating plates 19 are each fixedly connected with a threaded rod 110, a plurality of threaded grooves 111 are provided at the bottom of the feeding trough frame 11, a weighing sensor 112 is fixedly connected to the bottom of the inner wall of the feeding trough frame 11, a bottom spring 113 is fixedly connected to the top surface of the weighing sensor 112, and a stop column 16 is fixedly connected to the bottom of the inner wall of the feeding trough frame 11.

[0039] Wherein: the breeder can set the weight of the feed required to be weighed by the weighing sensor 112 through the external controller.

[0040] The feed bin 14 stores a prepared feed mixture, which is specifically a mixture of powdered feed such as cornmeal, soybean meal, bran, etc., granular feed and clean water, and the prepared feed mixture is a paste feed.

[0041] Among them: Reference Figure 1 As shown, the silo 14 and the rotating plate 19 located in the middle are located in the same vertical plane.

[0042] Among them: Reference Figure 5 As shown, the rotating plate 19 is embedded in the silo 14 , the upper surface of the rotating plate 19 and the upper surface of the silo 14 are on the same horizontal plane, and the threaded rod 110 passes through the carrier plate 18 and is fixedly connected to the rotating plate 19 .

[0043] Among them: Reference Figure 5 As shown, the rotating plate 19 is configured to have a top surface with a plurality of fan-shaped grooves in a circular array, so as to provide a height difference on the top surface of the rotating plate 19.

[0044] The threaded rod 110 is threadedly connected to the thread groove 111 , and the weighing sensor 112 , the bottom spring 113 and the stop column 16 are all sleeved on the threaded rod 110 located in the middle.

[0045] Wherein: one end of the bottom spring 113 away from the weighing sensor 112 is fixedly connected to the lower surface of the carrier plate 18 .

[0046] Among them: the weighing sensor 112 and multiple solenoid valves 17 are electrically connected through the controller. Specifically, the breeder can open the solenoid valve 17 through the external controller, so that the bottom of the feed pipe of the silo 14 is no longer closed, so that the feed inside the storage space of the silo 14 leaks out from the feed pipe to the bottom. When the weighing sensor 112 detects that the weight of the feed carried on the carrier plate 18 is sufficient, the weighing sensor 112 closes the solenoid valve 17 through the external controller, so that the inside of the silo 14 is sealed.

[0047] Among them: the breeder can open the feed cover 15 and add feed into the feed bin 14.

[0048] The stop post 16 is used to limit the lowest point of the sliding position of the carrier plate 18 inside the feeding trough frame 11.

[0049] Among them: in the initial state, that is, the top of the carrier plate 18 is empty, the feed inside the silo 14 does not fall downward, the carrier plate 18 does not slide downward inside the feeding trough frame 11, and the bottom spring 113 does not produce elastic deformation.

[0050] When the quantitative feeding component is in use, the breeder opens the solenoid valve 17 through the external controller, so that the feed discharge pipe of the silo 14 is no longer closed, so that the paste feed inside the silo 14 leaks out from the feed discharge pipe to the bottom, and the feed inside the silo 14 leaks out to the top of the carrier plate 18. As the feed on the top of the carrier plate 18 accumulates, the carrier plate 18 is affected by the gravity of the feed and slides downward inside the feeding trough frame 11, and the bottom spring 113 is elastically compressed. At this time, the weight of the feed on the top of the carrier plate 18 is detected by the weighing sensor 112 through the bottom spring 113.

[0051] As the carrier plate 18 moves downward inside the feeding trough frame 11, the threaded rod 110 is driven to move downward synchronously. Under the action of the internal thread of the thread groove 111, the threaded rod 110 rotates while moving downward, and the threaded rod 110 also drives the rotating plate 19 to rotate synchronously. Then, when the paste feed accumulates on the top surface of the carrier plate 18, it is synchronously driven by the rotating plate 19 to mix and stir, so that the paste feed is further mixed evenly, and the sedimentation and stratification generated when the paste feed is stored in the silo 14 is destroyed.

[0052] When the weighing sensor 112 detects sufficient weight, the weighing sensor 112 closes the solenoid valve 17 through the external controller, so that the interior of the silo 14 is sealed, and the feed inside the silo 14 stops falling. At this time, the feed on the top of the carrier plate 18 is the weight of the feed required by the breeder. Compared with the existing method of only relying on the solenoid valve 17 to control the falling time of the feed, this method is not affected by changes in the physical properties of the feed, and can ensure that the pigs can get an accurate amount of feed each time they are fed, which is conducive to accurate nutrition supply and meets the needs of pigs at different growth stages and health conditions.

[0053] At the same time, when the carrier plate 18 moves, it can drive the rotating plate 19 to rotate, so that the paste feed located on the top of the carrier plate 18 is driven to be mixed and stirred, thereby avoiding sedimentation and stratification of the paste feed when it is stored in the silo 14. The rotation of the rotating plate 19 drives the mixing, which can break this layered structure and make the feed components evenly distributed in the vertical direction, thereby ensuring the uniformity of the feed mixing as much as possible, ensuring that the pigs can take in balanced nutrition every time they eat, and avoiding the growth affected by excessive or low local nutrients.

[0054] As the feed on the top of the carrier plate 18 is consumed by the pigs, the pressure on the carrier plate 18 is reduced. Under the elastic expansion of the bottom spring 113, the carrier plate 18 moves upward inside the feeding trough frame 11, and at the same time, the threaded rod 110 moves upward inside the threaded groove 111, so that the threaded rod 110 rotates in the opposite direction, which can achieve continuous mixing of the feed while the pigs consume the feed, and can effectively prevent the paste feed from drying and sticking to the carrier plate 18 and the feeding trough frame 11, which is conducive to the pigs' smooth feeding.

[0055] When the feed on the top of the carrier plate 18 is completely eaten by the pigs, the bottom spring 113 drives the carrier plate 18 to completely return to its original position, and the quantitative feeding assembly also returns to its initial state.

[0056] Embodiment 2:

[0057] In the past, pig trough designs were often designed based on the convenience and cost of large-scale production, which often adopted relatively uniform standard sizes and shapes, resulting in the depth and volume of most troughs being fixed. However, for pigs, a suitable trough volume allows them to eat more comfortably. When there is less feed, pigs may need to look for food in the corners or at the bottom of the trough, which increases the difficulty of eating. This is especially true for piglets. Their smaller size and limited eating ability make it difficult for them to get enough food when faced with a large-volume trough with less feed, affecting their eating experience and may even lead to insufficient feeding, affecting their growth and development.

[0058] Reference Figures 1 to 11As shown, in order to solve the above-mentioned problems, a volume self-adjusting component is further provided on the feeding trough frame 11, and the volume self-adjusting component includes four slide grooves 21, and the four slide grooves 21 are arranged in a rectangular array on the top surface of the carrier plate 18, and the four slide grooves 21 are grouped in pairs, and a multi-section hollow telescopic plate 22 is slidably connected in two slide grooves 21 of the same group, and the end of the multi-section hollow telescopic plate 22 connected to the slide groove 21 is the telescopic end, and the end of the multi-section hollow telescopic plate 22 away from the slide groove 21 is the fixed end, and the bottom surfaces of the two multi-section hollow telescopic plates 22 are respectively fixedly connected with a silicone plate 23, and the feeding trough Two inclined slides 24 are symmetrically fixedly connected to the outer wall of the frame 11 on one side close to the support rod 13, and a vertical slide 25 is fixedly connected to one end of the fixed end of the two multi-section hollow telescopic plates 22 close to the inclined slide 24. A horizontal slide 26 is fixedly connected to the top surface of the carrier plate 18, and two limiting slides 27 are slidably connected to the horizontal slide 26. The lower surface of the carrier plate 18 is fixedly connected to four bottom rods 28 in a rectangular array, and the bottom ends of the four bottom rods 28 are each rotatably connected to a rotating shaft 29, and each of the four rotating shafts 29 is provided with a sealing belt 210, and each of the four rotating shafts 29 is provided with a clockwork spring 211.

[0059] The silicone plate 23 is used to fit the top shape of the carrier plate 18 , specifically, to fit the upper surface of the rotating plate 19 .

[0060] Among them: Reference Figure 2 As shown, the two inclined slides 24 are arranged in an inclined shape, and the ends of the two inclined slides 24 that are close to each other are the higher ends, and the ends of the two inclined slides 24 that are away from each other are the lower ends.

[0061] Among them: Reference Figure 2 As shown, the two vertical slides 25 extend away from one end of the corresponding multi-section hollow telescopic plate 22 to a side close to the support rod 13.

[0062] Among them: Reference Fig.11 As shown, the top end of the vertical slide 25 is horizontally slidably connected to the feeding trough frame 11.

[0063] Among them: Reference Figure 2 As shown, one end of the transverse slideway 26 away from the carrier plate 18 extends to the outer wall of the feeding trough frame 11 close to the support rod 13.

[0064] Among them: Reference Fig. 9 As shown, the two limiting slide posts 27 slide on the corresponding vertical slideway 25 and the inclined slideway 24 respectively.

[0065] Among them: Reference Figure 7 As shown, two ends of the clockwork spring 211 are fixedly connected to the bottom rod 28 and the rotating shaft 29 respectively.

[0066] Among them: Reference Figure 7 , Fig.10 and Fig.11 As shown, the sealing belt 210 is wound around the rotating shaft 29, and the end of the sealing belt 210 away from the rotating shaft 29 passes through the carrier plate 18 and is fixedly connected to the multi-section hollow telescopic plate 22. The four sealing belts 210 are respectively arranged at the bottom of one end of the four slide grooves 21 close to each other. Specifically, the four sealing belts 210 are grouped in pairs and are respectively fixedly connected to the two ends of the bottom of the two multi-section hollow telescopic plates 22.

[0067] Among them, the function of the sealing belt 210 is to prevent the paste feed from flowing into the chute 21 and affecting the movement of the multi-section hollow telescopic plate 22. As the multi-section hollow telescopic plate 22 moves, it can drive the rotating shaft 29 to elastically deform, and drive the sealing belt 210 to unwind and rewind on the rotating shaft 29, so that the chute 21 on one side of the two ends of the multi-section hollow telescopic plate 22 close to the center of the carrier plate 18, that is, the chute 21 within the effective feed volume range of the feed, is always covered by the sealing belt 210 to prevent the paste feed from entering the chute 21.

[0068] Among them: In the initial state, the volume self-adjusting component is in the attached Figure 1 In the state shown in the figure, the carrier plate 18 is located at a position near the top of the feeding trough frame 11, specifically, when the feeding has not started, the two multi-section hollow telescopic plates 22 are located at the end of the corresponding two slide grooves 21 closest to the center of the carrier plate 18, at this time, the limit slide 27 is located at the highest point of the inclined slide 24, the limit slide 27 is located at the highest point of the vertical slide 25, and the clockwork spring 211 does not produce elastic deformation.

[0069] Specifically, in the initial state, the effective feed volume at the top of the carrier plate 18 is the smallest, and there is only a top opening area formed between the top of the carrier plate 18 and the two multi-section hollow telescopic plates 22 .

[0070] When the volume self-adjusting component is used, it is divided into two use stages. In the first use stage, the carrier plate 18 is in the process of moving downward inside the feeding trough frame 11. As the carrier plate 18 moves downward, the carrier plate 18 drives the telescopic ends of the multi-section hollow telescopic plates 22 to move downward synchronously through the slide grooves 21, and the fixed ends of the multi-section hollow telescopic plates 22 are connected to the horizontal sliding connection of the feeding trough frame 11 through the vertical slides 25 and are limited. At this time, the telescopic ends of the multi-section hollow telescopic plates 22 move downward, and as the carrier plate 18 moves downward, the carrier plate 18 also moves downward. The horizontal slide 26 will be driven to move downward synchronously. Since the limit slide 27 slides inside the inclined slide 24, the vertical slide 25 and the horizontal slide 26 at the same time, the movement of the limit slide 27 will be limited by the three at the same time. Specifically, the horizontal slide 26 moves downward while driving the limit slide 27 downward, so that the limit slide 27 drives the vertical slide 25, so that the vertical slide 25 moves along the track of the inclined slide 24, that is, the vertical slide 25 drives the fixed end of the multi-section hollow telescopic plate 22 to move from the inclined slide 24 moves from the high point to the low point, that is, in the process of the carrier plate 18 moving downward, the telescopic end of the multi-section hollow telescopic plate 22 moves downward, and the fixed end of the multi-section hollow telescopic plate 22 moves away from the center of the carrier plate 18. Combined with the feed addition in the quantitative feeding component, the carrier plate 18 is in a state of continuous feed addition at this time, so the carrier plate 18 will continue to move downward, so that the multi-section hollow telescopic plate 22 moves to both sides, so that the effective volume of the top of the carrier plate 18 increases, so that the effective feed volume at the top of the carrier plate 18 can change with the weight of the feed. This adaptive volume change can effectively prevent the feed from overflowing due to insufficient volume. At the same time, the adaptive volume can provide a suitable feeding space according to the amount of feed. When the amount of feed is large, pigs can easily eat in a spacious space without having to look for food in a crowded environment. When the amount of feed is small, the reduction in space enables pigs to obtain food more concentratedly, reducing the time and energy consumption of looking for food and improving feeding efficiency.

[0071] The second use stage of the volume self-adjusting component is when the carrier plate 18 moves upward inside the feeding trough frame 11, that is, when the feed within the effective feed volume range of the carrier plate 18 is consumed, the volume self-adjusting component performs the above reverse operation, specifically: when the carrier plate 18 is rising, the multi-section hollow telescopic plates 22 on both sides thereof move toward each other, and the effective feed volume range on the upper part of the carrier plate 18 is reduced, that is, the paste feed is pushed by the two multi-section hollow telescopic plates 22 to move toward the center position of the carrier plate 18, so that the paste feed is gradually concentrated, which can effectively reduce the contact area between the paste feed and the air, reduce the oxidation rate of the paste feed, and thus maintain the freshness and nutritional value of the paste feed.

[0072] At the same time, the two multi-section hollow expansion plates 22 shrink inwardly to concentrate the remaining paste feed in the central area of ​​the carrier plate 18, and the lifting of the carrier plate 18 makes the pig's feeding area shallower, making it easier for the pig to find and obtain food. This is especially important for piglets or weaker pigs, who do not need to spend too much energy to find a small amount of food scattered in a large area of ​​the trough when eating, thereby improving the feeding efficiency.
