Technical Field

[0001] This utility model relates to the field of pig farrowing crate technology, specifically a sow farrowing crate restraint device to prevent crushing injuries. Background Technology

[0002] Pig farrowing crates are specialized equipment used in modern pig farms for sow farrowing and piglet nursing. They adopt a raised-bed feeding mode and modular design, and are mainly composed of components such as sow positioning frames, piglet pens, slatted floors, and heat-insulating boxes. Their core functions include reducing piglet mortality through anti-crushing bars, using a slatted floor system to achieve dry and wet separation to improve hygiene conditions, and providing a constant-temperature nursery space for newborn piglets.

[0003] Currently, sows need to feed after farrowing, and they need to stand while feeding. During this time, piglets can easily get under the sow's abdomen. As a result, when the sow finishes feeding and lies down, the piglets are easily crushed or killed, causing economic losses. Improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a sow farrowing crate restraint device to prevent crushing injuries, thereby solving the problem mentioned in the background art that sows are prone to crushing and killing piglets after using the farrowing crate for delivery and feeding.

[0006] The first driving-off component includes a fixed frame that is slidably connected to the barrier, a rotating shaft that is rotatably connected to the inside of the fixed frame, and a driving-off strip that is fixedly connected to the bottom of the rotating shaft.

[0007] Preferably, the partition is arranged symmetrically about the bisecting line of the base, a fixing frame is provided on the inner side of the partition on one side of the base, and a first hydraulic cylinder is fixedly connected to the outer side of the partition, with one end of the first hydraulic cylinder fixedly connected to the fixing frame.

[0008] Preferably, a drive motor is fixedly connected to one end of the fixing frame, and the shaft of the drive motor is connected to one end of the rotating shaft.

[0009] Preferably, the bottom of the partition has an opening with varying heights, and a sensor is installed on the top side of the partition.

[0010] Preferably, the structures of the second and third driving-off components are the same as those of the first driving-off component.

[0011] Preferably, the driving strips are made of rubber, and the driving strips are distributed longitudinally at equal intervals about the bottom of the rotating shaft, with the lengths of the driving strips being staggered.

[0012] Preferably, the second hydraulic cylinders are symmetrically distributed about the bisector of the base, and the second hydraulic cylinders are fixed inside the base by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This device improves the safety of piglet feeding, avoids the phenomenon of sows lying down after eating and crushing piglets to death, and reduces economic losses in breeding.

[0015] (2) This device sets a first driving component, a second driving component and a third driving component on the inside of the partition. The fixed frame of the first driving component, the second driving component and the third driving component can move in a straight line after the sow stands up.

[0023] 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.

[0024] Please see Figure 1-5This utility model provides a technical solution: a sow farrowing crate restraint device to prevent crushing injuries, including a farrowing crate frame 1, with a partition 2 and a base 5 fixedly connected to the inner wall of the farrowing crate frame 1. A door is hinged to the rear end of the farrowing crate frame 1, which can be opened to facilitate the entry of the sow. The partition 2 is symmetrically arranged about the bisector of the base 5. A fixing frame 43 is provided on the inner side of the partition 2 on one side of the base 5. A first hydraulic cylinder 41 is fixedly connected to the outer side of the partition 2. One end of the first hydraulic cylinder 41 is fixedly connected to the fixing frame 43. This structure allows the fixing frame 43 to be adjusted by pushing it through the first hydraulic cylinder 41, facilitating the fixing frame 43 to enter under the sow's abdomen for driving. A drive motor 44 is fixedly connected to one end of the fixing frame 43. The shaft of the drive motor 44 is connected to one end of the rotating shaft 45. The drive motor 44 in this structure is a stepper motor, which drives the rotating shaft 45 to swing left and right. The bottom of the partition 2 has openings of varying heights to allow piglets of different heights to pass through. A sensor 3 is installed on the top side of the partition 2; this sensor 3 is a distance sensor. When the sow stands up and approaches the sensor 3, the sensor 3 senses the movement and sends a signal to the PLC controller, causing the PLC controller to drive the first hydraulic cylinder 41, the drive motor 44, and the second hydraulic cylinder 6 to operate synchronously. The second hydraulic cylinder 6 is fixedly connected inside the base 5, and is symmetrically distributed about the bisector of the base 5. The second hydraulic cylinder 6 is fixed inside the base 5 with bolts. This structure includes the drive motor 44 and the second hydraulic cylinder 6. The first hydraulic cylinder 41 and sensor 3 are controlled in coordination by a PLC. A sewage hopper 8 is inserted into the top of the base 5. Grid plates 7 are fixedly connected to the top of the sewage hopper 8 and the inner walls on both sides of the farrowing frame 1. The sewage hopper 8 and the base 5 form a lifting connection. The partition 2 is located on the top side of the base 5. The partition 2 is equipped with a first driving assembly 4, a second driving assembly 9, and a third driving assembly 10. The structures of the second driving assembly 9 and the third driving assembly 10 are the same as those of the first driving assembly 4. In this structure, the first driving assembly 4, the second driving assembly 9, and the third driving assembly 10 correspond to the hind legs, forelegs, and lower abdomen of the sow, respectively, avoiding the sow's hind legs and forelegs and preventing discomfort. The second hydraulic cylinder 6 can drive the sewage hopper 8 to rise automatically. After the sewage hopper 8 is raised, it can be staggered with the grid plates 7 on both sides of the partition 2, thereby preventing piglets on the grid plates 7 on both sides from entering the sow's abdomen. The first driving component 4 includes a fixed frame 43 that is slidably connected to the partition 2. A rotating shaft 45 is rotatably connected to the inner side of the fixed frame 43. A driving strip 42 is fixedly connected to the bottom of the rotating shaft 45. The driving strip 42 is made of rubber, which can drive the piglets while avoiding injury to the sow and piglets. The driving strip 42 is evenly distributed longitudinally about the bottom of the rotating shaft 45. The length of the driving strip 42 is staggered. During the rotation of the rotating shaft 45, the driving strip 42 can drive the driving strip 42 to swing left and right, thereby driving the piglets under the sow's front feet, abdomen and hind feet back to the outer area of ​​the partition 2, avoiding the piglets being crushed.

[0025] Working principle: When using this anti-crushing sow farrowing crate limiting device, the sow is placed on the grid plate 7 at the top of the base 5 for farrowing and nursing. Piglets are placed in the grid plate 7 areas on both sides of the partition 2. When the sow needs to eat after farrowing, she stands up. After standing, the sow is located inside the sensor 3, which triggers the sensor 3. Under the control of the PLC controller, the first hydraulic cylinder 41, drive motor 44, and second hydraulic cylinder 6 of the first driving assembly 4, the second driving assembly 9, and the third driving assembly 10 are activated. In operation, the second hydraulic cylinder 6 pushes the sewage hopper 8 and the sow to rise automatically. At this time, the sow and piglets are separated by misalignment. Meanwhile, the first hydraulic cylinder 41 of the first driving assembly 4, the second driving assembly 9 and the third driving assembly 10 pushes the fixing frame 43 to be located in front of the sow's forelegs, under its abdomen and behind its hind legs, respectively. At the same time, the drive motor 44 drives the rotating shaft 45 to rotate, causing the driving bar 42 at the bottom of the rotating shaft 45 to oscillate left and right. The piglets in this area are driven to move to both sides of the partition 2 by the movement of the driving bar 42, reducing the occurrence of piglets being crushed.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
