Description

Technical Field

[0001] This utility model relates to the field of livestock breeding equipment technology, specifically a foldable piglet feeding trough for sow farrowing crates. Background Technology

[0002] In modern, large-scale pig farming, farrowing crates are key equipment for ensuring the safety of sows during farrowing and improving the survival rate and uniformity of piglets. A sow farrowing crate typically consists of a sow confinement area, two piglet activity areas (heating and supplementary feeding areas) on both sides, and a piglet heat box. From about 7 days after birth (the creeping period) until weaning, piglets need to be provided with a special feed trough to stimulate the development of their digestive system, supplement insufficient sow milk, and lay the foundation for successful weaning.

[0003] In existing technologies, feed troughs for supplemental feeding of piglets are typically placed directly on the floor of the sow's farrowing crate, with ample feed placed inside the trough, such as:

[0004] Chinese patent discloses an automatic plastic feeding trough for piglets (authorization announcement number CN207252509U). This patented technology uses a material tank to ensure that feed does not leak. When in use, the top of the material tank is covered with a lid, which is clean and hygienic, has a long service life, and is corrosion resistant. When in use, the lid is opened, the feed is put into the material tank, and the lid is closed. The feed leaks down from the circumference of the adjusting column, so that the bottom circumference of the feed tray is always covered with feed. The feed is continuously replenished as the piglets eat, without waste. It is hygienic, saves feed, and reduces the cost for farmers.

[0005] Chinese patent discloses a piglet feeding trough for pig farms (authorization announcement number CN217470968U). The patented technology features a partition mechanism inside the feeding trough. By moving the partitions horizontally and adjusting the spacing between adjacent partitions according to the actual situation of the piglets, feed can be placed between adjacent partitions. The smaller spacing between partitions makes it difficult for larger pigs to compete for the feed, making it more beneficial for smaller piglets to eat. This achieves the beneficial effect of easily partitioning the inside of the feeding trough, reducing competition for feed, and making it more conducive to piglets eating.

[0006] However, this fixed placement method has significant drawbacks: because the main body of the trough is always in a low position that piglets can easily reach and the food is constantly exposed, piglets lack the awareness of fullness and are very likely to continue eating without knowing they are full. This not only causes excessive waste of feed, but more importantly, overeating will damage the digestive health of piglets and affect their normal growth and development, becoming a major pain point in feeding management. Utility Model Content

[0007] The purpose of this invention is to provide a foldable piglet feeding trough for sow farrowing crates, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A foldable piglet feeding trough for sow farrowing crates includes an L-shaped bracket. Two support plates are symmetrically fixed to the front surface of the vertical section of the L-shaped bracket in the left-right direction. A swing arm is rotatably connected to the opposite side surface of the two support plates. A support rod is fixed between the upper ends of the opposite side surfaces of the two swing arms. A connecting sleeve is fixed to the upper ends of the opposite side surfaces of the two swing arms.

[0010] The upper surface of the horizontal section of the L-shaped bracket is symmetrically provided with two folding mechanisms in the left and right directions.

[0011] A feeding mechanism is provided between the lower ends of the opposite surfaces of the two swing arms.

[0012] As a further embodiment of this utility model: the folding mechanism includes a connecting column, a C-shaped block is fixedly connected to the upper end of the front surface of the connecting column, a telescopic cylinder is rotatably connected to the inner side of the C-shaped block, and a connecting bolt is movably connected through the telescopic end of the telescopic cylinder.

[0013] As a further embodiment of this utility model: the feeding mechanism includes a feeding trough body, and multiple partitions are fixedly connected to the inside of the feeding trough body from left to right. A seat bearing is fixedly connected to the upper end of both the left and right sides of the feeding trough body, and a fixing rod is installed inside the seat bearing.

[0014] As a further embodiment of this utility model: the lower end of the connecting column is fixed to the upper surface of the L-shaped bracket, and one end of the connecting bolt is threaded into the inside of the connecting sleeve.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model achieves piglet feeding management and control through a foldable design: Firstly, the telescopic cylinder drives the swing arm to rotate, allowing the main body of the feed trough to flexibly switch between a low feeding position and a high idle position, satisfying the piglets' feeding needs while also raising the feed trough in time to prevent overfeeding; Secondly, the cooperation between the folding mechanism and the seat bearing ensures that the main body of the feed trough remains vertically stable during the lifting and lowering process, and the counterweight effectively reduces shaking and prevents feed spillage; Thirdly, the partitioned feed trough ensures that piglets eat evenly, while the overall structure significantly saves space in the sow farrowing crate when folded horizontally, reducing the risk of equipment interference; This design greatly improves the convenience and scientific nature of feeding management and effectively optimizes feeding efficiency.

[0023] Please see Figure 1 and Figure 2 In this embodiment of the utility model, a foldable piglet feeding trough for sow farrowing crates includes an L-shaped bracket 1. Two support plates 2 are symmetrically fixed to the front surface of the vertical section of the L-shaped bracket 1 in the left and right directions. A swing arm 3 is rotatably connected to the opposite side surface of the two support plates 2. A support rod 4 is fixed between the upper ends of the opposite side surfaces of the two swing arms 3, and a connecting sleeve 5 is fixed to the upper ends of the opposite side surfaces of the two swing arms 3.

[0024] Two support plates 2 are symmetrically welded to the front surface of the vertical section of the L-shaped bracket 1. Each support plate 2 is hinged to a swing arm 3 through a pivot, so that the swing arm 3 can rotate around the hinge point.

[0025] Two folding mechanisms 6 are symmetrically arranged on the upper surface of the horizontal section of the L-shaped bracket 1 in the left and right directions. The folding mechanism 6 includes a connecting column 7. The lower end of the connecting column 7 is fixed to the upper surface of the L-shaped bracket 1. A C-shaped block 8 is fixed to the upper end of the front surface of the connecting column 7. A telescopic cylinder 9 is rotatably connected to the inner side of the C-shaped block 8. A connecting bolt 10 is movably connected through the telescopic end of the telescopic cylinder 9. One end of the connecting bolt 10 is threaded to the inside of the connecting sleeve 5.

[0026] C-shaped block 8 is welded to connecting column 7, and its open side is hinged to the cylinder tail of telescopic cylinder 9 through a pin, so that telescopic cylinder 9 can swing around the pin.

[0027] The telescopic cylinder 9 has a through hole at its telescopic end. After the connecting bolt 10 passes through the through hole, its threaded end is screwed into the connecting sleeve 5 to form an adjustable push-pull point.

[0028] A feeding mechanism 11 is provided between the lower ends of the opposite surfaces of the two swing arms 3;

[0029] The vertical section of the L-shaped bracket 1 is fixed to the railing of the sow farrowing crate by bolts on the side surface away from the support plate 2.

[0030] The telescopic cylinder 9 is preferably an electric cylinder. When it extends, the two swing arms 3 are in a nearly vertical state. At this time, the height of the feeding mechanism 11 is lower, making it easier for piglets to eat. When the telescopic cylinder 9 retracts, the two swing arms 3 rotate to a horizontal state, thereby raising the height of the feeding mechanism 11 so that piglets cannot reach it, thus preventing piglets from continuing to eat without knowing they are full.

[0031] exist Figure 1 and Figure 3 In the middle: the feeding mechanism 11 includes a feeding trough body 12. Multiple partitions 13 are fixedly connected inside the feeding trough body 12 from left to right. Seat bearings 14 are fixedly connected to the upper ends of the left and right side surfaces of the feeding trough body 12. Fixing rods 15 are installed inside the seat bearings 14. The left and right fixing rods 15 are respectively connected to the lower ends of the left and right swing arms 3.

[0032] Multiple partitions 13 divide the interior of the trough body 12 into multiple areas for evenly placing feed;

[0033] The pedestal bearing 14 includes a bearing housing and a bearing fixed inside the bearing housing. The bearing includes an outer bearing ring and an inner bearing ring that rotates inside the outer bearing ring. The outer bearing ring is fixed in the bearing housing, and the bearing housing is fixed to one side surface of the feed tank body 12. The fixing rod 15 is fixed in the inner bearing ring. Therefore, the pedestal bearing 14 and the fixing rod 15 are in a state of mutual rotation.

[0034] The cooperation between the seat bearing 14 and the fixed rod 15 ensures that the main body 12 of the feeding trough remains vertical as it rotates with the swing arm 3.

[0035] exist Figure 3 In the middle: a counterweight 16 is fixedly attached to the lower surface of the main body 12 of the feeding trough;

[0036] The counterweight 16 is preferably made of stainless steel, which further ensures the stability of the main body 12 of the feeding trough and reduces its shaking amplitude.

[0037] The working principle of this utility model is as follows: First, the vertical section of the L-shaped bracket 1 is fixed to the railing of the sow farrowing crate by bolts; when piglets need to eat, the telescopic cylinder 9 is extended, and the telescopic end of the telescopic cylinder 9 pushes the connecting sleeve 5 through the connecting bolt 10, thereby driving the two swing arms 3 to rotate around the support plate 2 to a near-vertical state. At this time, the feeding trough body 12, which is connected to the lower end of the two swing arms 3 through the fixing rod 15 and the seat bearing 14, is lowered to a low position, and the piglets can eat the feed separated by the partition 13 in the feeding trough body 12; when feeding is not needed, the telescopic cylinder 9 is retracted, and the swing arms 3 are pulled to rotate to a horizontal state, thereby raising the feeding trough body 12 to a high position so that the piglets cannot reach the feed and overfeeding is prevented. During this process, the seat bearing 14 ensures that the feeding trough body 12 always maintains a vertical state, and the counterweight 16 enhances its stability.
