Description

Technical Field

[0001] This utility model belongs to the field of aquaculture pen technology, specifically relating to a feeding mechanism. Background Technology

[0002] In large-scale farms, farrowing crates are the places where sows give birth and nurse piglets. Currently, the sow feeding troughs commonly used on farrowing crates are mostly stamped type, which generally have the problems of shallow trough depth and low height of the front edge (i.e., the side away from the sow's feeding edge).

[0003] The above structure has the following drawbacks in actual use: First, because the feeding trough is shallow and the front edge is low, sows are very likely to push the feed out of the trough from the front edge during feeding, which wastes feed, increases feed costs, and pollutes the farrowing crate environment. Secondly, due to the low front edge, piglets can easily cross the feeding trough and fall out of the farrowing crate into the aisle, which can easily cause hoof injuries to the piglets, increase the workload of the feeders in catching them, and reduce the survival rate of the piglets. Secondly, the structural design of the trough failed to coordinate with the feed delivery unit, resulting in the height of both ends of the trough being lower than the feed delivery unit's inlet. This caused feed to easily splash out from both ends of the trough, further increasing feed waste. Finally, the existing feeding troughs are not easy to flip to an angle facing outwards from the farrowing bed, which increases the difficulty of cleaning and the labor intensity of employees. Utility Model Content

[0004] The purpose of this invention is to provide a feeding mechanism that solves the technical problems of feed being easily pushed out and wasted in existing farrowing crate feed troughs, piglets escaping by crossing the feed trough, feed splashing, and difficulty in cleaning.

[0005] This utility model discloses a feeding mechanism, including: The gate body includes a frame and a crossbeam. The crossbeam is fixedly installed on the upper part of the frame and together with the middle and lower part of the frame, they enclose a feeding window. The feeding trough is rotatably installed inside the feeding window. The top of the feeding trough has a flat feeding opening. The front edge of the feeding opening is located on the outside of the gate body, and the rear edge is located on the inside of the gate body. Positioning elements are provided on both sides of the feeding trough. Two limiting components are respectively installed on both sides of the feeding window to cooperate with the positioning component to restrict the rotation of the feeding trough in the feeding state and keep the feeding trough fixed. The feed delivery unit is installed on the outside of the gate body and above the feed trough, and has a downward-extending discharge port; In the feeding state, the feeding port faces obliquely upwards to the inside of the feeding window, and the front edge of the feeding port is higher than the rear edge, and the discharge port extends at least partially into the feeding port; In the cleaning state, the feeding port faces diagonally upwards and outwards from the outside of the feeding window, with the leading edge of the feeding port lower than the trailing edge, and the trailing edge of the feeding port abutting against the feed delivery unit.

[0006] This application reduces feed spillage during feeding by adopting a high-back design at the front edge of the feeding trough, effectively preventing piglets from crossing the feeding trough and improving piglet survival rate. Furthermore, by ensuring that the discharge port extends at least partially into the feeding port, feed is prevented from splashing out from both ends of the feeding trough due to impact, reducing feed waste and lowering feed costs. It also makes it easier to flip the feeding trough to an angle facing the outside of the farrowing crate, improving the convenience of cleaning the feeding trough.

[0007] Based on the above technical solution, the solution of this application can be further improved as follows: Preferably, the gate body includes: Two vertical beams are fixedly installed on both sides of the feeding window; The limiting components are respectively installed on the two vertical beams. This solution improves the structural stability of the gate and provides a stable installation for the two limiting components. It can effectively transmit the force generated when the sow eats to the entire gate body, ensuring overall stability, durability and reliability.

[0008] Preferably, the feeding trough includes a front wall, a rear wall, and a bottom wall; the front and rear walls are flat plates, and the bottom wall is an arc-shaped plate, smoothly transitioning between the front and rear walls; this design effectively prevents feed waste and piglet escape during feeding, reduces feed residue in the trough, and creates a smooth slope that guides wastewater to flow out naturally during cleaning, allowing residue and wastewater to be automatically drained under gravity, eliminating sanitary dead corners, and improving cleaning efficiency and cleanliness.

[0009] Preferably, the upper end of the front trough wall and the front edge of the feeding port are smoothly connected by an inwardly curved arc wall, and the upper end of the front trough wall is provided with multiple drainage holes. With this solution, the feed pushed out by the sow can be effectively guided back into the trough, improving the waste prevention effect, and ensuring that the sewage after rinsing can be completely drained, avoiding water accumulation and ensuring the cleaning effect.

[0010] Preferably, the outer periphery of the feeding port is provided with an outwardly folded arc-shaped flange; this design enhances the structural strength and rigidity of the feeding port, effectively prevents deformation and cracking of the feeding trough, and eliminates sharp edges through the arc design, reducing the risk of scratches and improving the durability and safety of the equipment.

[0011] Preferably, it includes: Two rotating components are coaxially arranged on both sides of the feeding trough; The rotating assembly includes: A support plate is installed on the side of the feeding window and has an upward-facing U-shaped groove. The rotating shaft is connected at one end to the side wall of the feeding trough and at the other end to the U-shaped groove. This design ensures smooth rotation of the feeding trough between feeding and cleaning states, and also allows the feeding trough to be lifted directly upwards for quick disassembly when needed, facilitating replacement and improving maintenance portability.

[0012] Preferably, the positioning element is a positioning rod, and the limiting component includes: A vertical plate is installed on the vertical beam and has an internally continuous mounting cavity, and a limiting groove communicating with the mounting cavity is provided on the outer side laterally. A stop block is rotatably installed in the mounting cavity and can hang down naturally under the action of gravity to pass through the opening of the limiting groove, thereby preventing the positioning rod from disengaging from the limiting groove. A wrench, located on the stop block and extending above the vertical plate, is used to drive the stop block to rotate so that it disengages from the opening of the limiting slot. This solution achieves automatic locking and rapid unlocking based on gravity, and can complete the unlocking operation with one hand while ensuring the reliability of locking, greatly improving the portability, safety and work efficiency of the equipment.

[0013] Through the above technical solution, this utility model achieves the following beneficial effects: 1. This application reduces feed spillage during feeding by adopting a high-back design at the front edge of the feed trough, effectively preventing piglets from crossing the feed trough and improving the survival rate of piglets. Furthermore, by making the discharge port at least partially extend into the feeding port, feed is prevented from splashing out from both ends of the feed trough due to impact, reducing feed waste and lowering feed costs. It also makes it easier to flip the feed trough to an angle facing the outside of the farrowing crate, improving the convenience of cleaning the feed trough. 2. By setting an inwardly curved arc wall and opening multiple drainage holes at the upper end of the front trough wall, this application can effectively guide the feed pushed out by the sow back into the trough, improve the waste prevention effect, and ensure that the sewage after rinsing can be completely drained, avoiding water accumulation and ensuring the cleaning effect.

[0016] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0017] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0019] Example: like Figure 1 As shown in the figure, this application discloses a feeding mechanism for sow farrowing crates in large-scale farms. It provides sows with a feeding device that can prevent feed waste, avoid piglets from escaping, facilitate automated feeding, and allow for thorough cleaning. Its specific structure includes: a gate body 1, a feeding trough 2, two limiting components 3, and a feed delivery unit 4.

[0020] The gate body 1 is installed in the gate frame and is rotatably connected to one side of it to facilitate lateral flipping, which serves as isolation and structural support. The gate body 1 includes a frame 11 and a crossbeam 12. The crossbeam 12 is fixedly installed on the upper part of the frame 11 and together with the middle and lower part of the frame 11, it forms a feeding window 101, thereby defining the activity space of the trough 2 and the feeding area of ​​the sow.

[0021] The feed trough 2 is rotatably installed inside the feeding window 101 to achieve state switching; the top of the feed trough 2 has a flat feeding opening 201, the front edge of the feeding opening 201 is located outside the gate body 1, and the rear edge is located inside the gate body 1; positioning members 202 are provided on both sides of the feed trough 2.

[0022] Two limiting components 3 are respectively installed on both sides of the feeding window 101 to cooperate with the positioning component 202 to restrict the rotation of the feeding trough 2 in the feeding state and keep the feeding trough 2 fixed.

[0023] The feed delivery unit 4 is installed on the outside of the gate body 1 and above the feed trough 2. It can be a free feeder, a feeding pipe, etc., and has a downward-extending discharge port 401, which is responsible for conveying feed to the feed trough 2 through the discharge port 401.

[0024] In the feeding state, the feeding opening 201 faces the inside of the feeding window 101 at an angle to the upper side, and the front edge of the feeding opening 201 is higher than the rear edge. Due to the high front edge, a high-back design is formed, which effectively prevents the sow from pushing the feed out from the front edge and forms a barrier that is difficult for piglets to cross, preventing piglets from climbing out of the farrowing crate through the feeding trough 2. The low rear edge makes it easy for the sow to stick her head into the feeding opening 201 to eat. The discharge outlet 401 extends at least partially into the feeding opening 201, which avoids the problem of feed splashing out from both ends of the feeding trough 2 due to impact.

[0025] In the cleaning state, the feeding port 201 faces the outside of the feeding window 101 at an angle to the upper side, and the front edge of the feeding port 201 is lower than the rear edge, so that the feeder can easily wash the feed trough 2 without entering the farrowing bed and can stand in the passage. The rear edge of the feeding port 201 abuts against the feed delivery unit 4, and the feed delivery unit 4 can be used as a stable fulcrum to prevent the feed trough 2 from overturning during cleaning. At the same time, the feed trough 2 is firmly supported at an angle that is easy to clean, freeing the operator's hands.

[0026] This invention reduces feed spillage during feeding by adopting a high-back design at the front edge of the feeding trough 2, effectively preventing piglets from crossing the feeding trough 2 and improving piglet survival rate. Furthermore, by having the discharge port 401 at least partially extend into the feeding port 201, feed is prevented from splashing out from both ends of the feeding trough 2 due to impact, reducing feed waste and lowering feed costs. It also makes it easier to flip the feeding trough 2 to an angle facing the outside of the farrowing crate, improving the convenience of cleaning the feeding trough 2.

[0027] In some embodiments, such as Figure 1 As shown, the gate body 1 includes two vertical beams 13, which are fixedly installed on both sides of the feeding window 101 to form structural support; wherein, the limiting component 3 is installed on the two vertical beams 13 respectively, thereby achieving a stable installation.

[0028] The above design improves the structural stability of the gate and provides a stable installation for the two limiting components 3, which can effectively transmit the force generated when the sow eats to the entire gate body 1, ensuring overall stability, durability and reliability.

[0029] In some embodiments, such as Figure 3 As shown, the feeding trough 2 includes a front trough wall 21, a rear trough wall 22 and a bottom trough wall 23; the front trough wall 21 and the rear trough wall 22 are flat plates, and the bottom trough wall 23 is an arc-shaped plate, which is smoothly connected between the front trough wall 21 and the rear trough wall 22.

[0030] Understandably, in the feeding state, the front trough wall 21 is in a nearly vertical state, thus forming a barrier to prevent sows from rooting around the feed and to prevent piglets from escaping, providing the maximum effective protection height; while in the cleaning state, the front trough wall 21 is in a downward inclined state towards the outside of the feeding window 101, thus forming a smooth slope that guides sewage and residue to flow out naturally. Under the action of gravity, water and dirt can flow smoothly along the front trough wall 21 to the outside of the trough, realizing automatic emptying.

[0031] Understandably, during feeding, the rear trough wall 22 forms an upward angle that tilts into the feeding window 101, making it easier for the sow to comfortably insert her head to eat, while also creating a height difference with the front edge.

[0032] Understandably, the arc-shaped design of the bottom wall 23 eliminates dead corners on the bottom surface, thus naturally guiding the dispersed feed to the center of the bottom of the trough, making it convenient for sows to lick and reducing feed residue in the trough; and when the feeding trough 2 is cleaned, water and residue can flow smoothly out along the arc surface, avoiding accumulation and facilitating cleaning.

[0033] Through the above design, feed waste and piglet escape are effectively prevented during feeding. The curved bottom has no dead corners, reducing feed residue in the trough. During cleaning, a smooth slope is formed to guide the wastewater to flow out naturally, so that the residue and wastewater in the trough are automatically drained under gravity, eliminating sanitary dead corners and improving cleaning efficiency and cleanliness.

[0034] Based on the above embodiments, such as Figure 1 and Figure 3 As shown, the upper end of the front groove wall 21 and the front edge of the feeding port 201 are smoothly connected by an inwardly curved arc wall 24, and the upper end of the front groove wall 21 is provided with multiple drainage holes 211.

[0035] Understandably, during feeding, the curved wall 24 forms an inwardly curved barrier that can guide the feed that the sow has pushed up back into the trough 2, instead of directly throwing it over the front edge, thus greatly improving the waste prevention effect.

[0036] Understandably, during the cleaning process, due to the addition of the arc-shaped wall 24, the connection between the front tank wall 21 and the arc-shaped wall 24 becomes the lowest point of the feeding trough 2; therefore, under the action of gravity, the residual sewage will collect here; so, by opening a drain hole 211 here, the residual sewage can be completely and automatically discharged, ensuring that the feeding trough 2 can dry quickly and avoiding water accumulation.

[0037] The above design effectively guides the feed pushed out by the sow back into the trough, improving the waste prevention effect and ensuring that the wastewater after rinsing can be completely drained, avoiding water accumulation and ensuring the cleaning effect.

[0038] In some embodiments, such as Figure 3 As shown, the outer periphery of the feeding port 201 is provided with an outwardly folded arc-shaped flange 25.

[0039] The above design enhances the structural strength and rigidity of the feeding port 201, effectively preventing deformation and cracking of the feeding trough 2. The arc-shaped design eliminates sharp edges, reduces the risk of scratches, and improves the durability and safety of the equipment.

[0040] In some embodiments, such as Figure 3 As shown, it includes two rotating components 5, which are coaxially arranged on both sides of the feeding trough 2, for rotating support at both ends of the feeding trough 2, thereby reducing stress concentration and improving support stability.

[0041] In this embodiment, as Figure 3 As shown, the rotating assembly 5 includes: The support plate 51 is installed on the side of the feeding window 101, preferably on the vertical beam 13, and has an upward-facing U-shaped groove 511 for supporting the rotating shaft 52. The rotating shaft 52 has one end connected to the side wall of the feeding trough 2 and the other end placed in the U-shaped groove 511, thus forming a supporting rotating pair, which ensures that the feeding trough 2 can be smoothly rotated between feeding and cleaning states.

[0042] It should be noted that when the feeding trough 2 is not lifted, the rotating shaft 52 is confined within the U-shaped groove 511, allowing the feeding trough 2 to freely rotate between the "feeding" and "cleaning" angle positions. When replacement is required, the operator can directly lift the feeding trough 2 vertically upwards using the upward-facing opening of the U-shaped groove 511, allowing the rotating shaft 52 to disengage from the U-shaped groove 511, thus completing the disassembly. The installation process is the reverse: simply align and lower the feeding trough 2. No tools are required, making the operation simple and convenient.

[0043] The above design ensures that the feed trough 2 can be smoothly flipped between feeding and cleaning states, and also allows the feed trough 2 to be lifted directly upwards for quick disassembly when needed, making it easy to replace and improving maintenance portability.

[0044] Based on the above embodiments, such as Figure 2 As shown, the positioning component 202 is a positioning rod, whose rod-shaped structure is easy to process and can withstand the force from the feeding trough 2. The limiting component 3 includes: a vertical plate 31, a stop block 32 and a wrench 33.

[0045] The vertical plate 31 is installed on the vertical beam 13 and has an internally connected mounting cavity 311, which provides space for the block 32 to be accommodated and rotated. A limiting slot 312 communicating with the mounting cavity 311 is provided on the outer side.

[0046] The stop block 32 is rotatably installed in the mounting cavity 311 and can hang down naturally under the action of gravity to pass through the opening of the limiting slot 312, thereby preventing the positioning rod from disengaging from the limiting slot 312.

[0047] A wrench 33 is mounted on the stop block 32 and extends above the vertical plate 31 to drive the stop block 32 to rotate so that it disengages from the opening of the limiting slot 312.

[0048] The working process of the aforementioned limit component 3 is as follows: When the feeding trough 2 is rotated to the feeding state, the positioning rod will enter the limiting slot 312 laterally. During the entry process, the positioning rod will push open and pass through the drooping block 32 to enter the bottom of the limiting slot 312. When the positioning rod is fully in place, the block 32 is no longer pushed and will automatically swing back to the drooping position under the action of gravity, thereby passing through the opening of the limiting slot 312 and blocking the exit path of the positioning rod, thus achieving automatic locking.

[0049] When the feeding trough 2 needs to be turned over for cleaning, the operator pulls down the wrench 33. The wrench 33 drives the stop block 32 to rotate in the mounting cavity 311, causing it to rise against gravity. As a result, its lower end retracts from the opening of the limiting slot 312. Thus, the opening of the limiting slot 312 is no longer blocked, the positioning rod can be moved out freely, and the feeding trough 2 is unlocked.

[0050] The above design enables automatic locking and rapid unlocking based on gravity, and while ensuring the reliability of locking, it can be unlocked with one hand, greatly improving the portability, security and work efficiency of the device.
