[0031] 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.
[0032] Reference Figures 1-4 The present invention provides an embodiment of a sow farrowing device, comprising a farrowing room 1, a bed board 2 fixedly connected inside the farrowing room 1, a restraint bar 3 fixedly connected to the top of the bed board 2 to ensure that the sow can be effectively restrained during farrowing, a receiving bed 4 provided inside the farrowing room 1, the receiving bed 4 being located behind the restraint bar 3, a nursing table 14 provided inside the farrowing room 1, auxiliary components provided inside the restraint bar 3, and a storage component provided inside the nursing table 14;
[0033] The auxiliary components include a rotating column 6 and a limiting plate 7. The rotating column 6 is rotatably connected inside the limiting pen 3, and the limiting plate 7 is fixedly connected to the outer wall of the rotating column 6. The position of the limiting plate 7 can be adjusted by the rotating column 6 to help limit the sow's range of motion. A worm gear 8 is fixedly connected to the outer wall of the rotating column 6, and a support block 9 is fixedly connected to the outer wall of the limiting pen 3. A worm 10 is rotatably connected inside the support block 9, and the worm 10 meshes with the worm gear 8. A knob 11 is fixedly connected to one end of the worm 10. A heat preservation box 5 is installed inside the farrowing house 1 to provide a warm and suitable environment for newborn piglets and prevent health problems caused by hypothermia. A lighting lamp 12 is installed inside the farrowing house 1. The lighting lamp 12 is located on the right side of the bed board 2 and can provide a certain amount of brightness to the sow's udder area to guide the piglets to nurse. A feeding rack 13 is installed inside the farrowing house 1.
[0034] Specifically, during farrowing, the sow is first guided into the gestation crate 3 to effectively restrict her movement. She is then positioned on her side above the bed board 2 for farrowing. The piglets born are placed on the receiving bed 4 behind the gestation crate 3, which facilitates care and monitoring of the piglets' vital signs, as well as necessary procedures such as cutting the umbilical cord, ensuring the piglets' health and safety. Throughout the farrowing process, the sow's udder always faces the right side of the gestation crate 3 (the side with the gestation plate 7) for easy feeding of the piglets. To further enhance stability and safety during farrowing, the rotation of the worm gear 10 can be controlled by rotating the knob 11. Rotating the worm gear 10 will drive the meshing worm wheel 8 to rotate. The worm gear 8 rotates, driving the internal rotating column 6. This allows the rotating column 6 to rotate inside the limiting cage 3. The rotating column 6, in turn, causes the limiting plate 7 on the outer wall to flip over. Once flipped, the limiting plate 7 immediately blocks the side of the sow, providing additional support and ensuring that the sow does not roll over during farrowing, thus preventing injury to the nursing piglets. This not only helps maintain the sow's stable posture but also provides additional physical support during farrowing to prevent the sow from rolling over. Furthermore, the effective limiting function of the limiting plate 7 ensures the safety of the piglets during farrowing, preventing them from accidentally crushing the nursing piglets and protecting their growth environment.
[0035] Reference Figure 1 and Figure 5 The storage assembly includes a first storage plate 15 and a second storage plate 16. The outer wall of the first storage plate 15 is fixedly connected to the inside of the nursing table 14, and the second storage plate 16 is slidably connected to the inside of the nursing table 14. A support plate 17 is fixedly connected to the inside of the nursing table 14, and a cylinder 18 is fixedly connected to the top of the support plate 17. A push rod 19 is fixedly connected to the output end of the cylinder 18. The push rod 19 passes through the inside of the first storage plate 15, and the top of the push rod 19 is fixedly connected to the bottom of the second storage plate 16. Driven by the cylinder 18, the push rod 19 can move the second storage plate 16 up and down to adjust the height of the stored items or the ease of retrieval as needed. A guide column 20 is fixedly connected to the inside of the nursing table 14, and the second storage plate 16 is slidably connected to the outer wall of the guide column 20 to provide additional storage space. The bottom of the nursing table 14 is equipped with casters 21, which can be easily moved when needed, providing flexible operating space. A handle 22 is fixedly connected to one side of the nursing table 14.
[0036] Specifically, when the sow is close to farrowing, the operator can use the casters 21 of the nursing table 14 to easily push the nursing table 14 to the appropriate position in the farrowing room 1. The nursing table 14 is equipped with a storage component for storing various items needed during the farrowing process, including farrowing tools, medicines, piglet care supplies, etc., so that the operator can quickly and conveniently access the required items during farrowing. For ease of operation, a cylinder 18 is fixed on the support plate 17 inside the nursing table 14. The cylinder 18 controls the sliding of the storage plate 16 on the outer wall of the guide column 20 through the push rod 19, thereby adjusting the size of the storage space and the height of the storage plate 16. This allows the operator to flexibly adjust the height and spatial layout of the storage plate as needed to accommodate the storage of different types of items and tools, making the entire farrowing process more efficient and orderly.
[0037] Working principle: When a sow is farrowing, she is first guided into the gestation crate 3 and laid on her side above the bed board 2 for farrowing. The piglets born can be placed on the receiving bed 4 behind the gestation crate 3 for easy care and umbilical cord cutting. During farrowing, the sow's udder faces the right side of the gestation crate 3 for easy nursing. The knob 11 can be turned to rotate the worm gear 10, which in turn rotates the meshing worm wheel 8. This causes the worm wheel 8 to rotate the internal rotating column 6 inside the gestation crate 3. The rotating column 6 causes the outer wall gestation plate 7 to flip, blocking the sow's side. This provides extra support for the sow during farrowing and prevents the sow from rolling over and crushing the nursing piglets, thus effectively supporting and gesturing the sow.
[0038] Before the sow is about to give birth, the operator can use the casters 21 at the bottom of the nursing table 14 to push the nursing table 14 to a suitable position in the farrowing room 1. The storage components inside the nursing table 14 are used to store various items needed for farrowing, such as farrowing tools, medicines, piglet care supplies, etc. The cylinder 18 fixed on the support plate 17 can control the second storage plate 16 to slide up and down on the outer wall of the guide column 20 through the push rod 19, thereby adjusting the size of the storage space and the height of the second storage plate 16 to meet the placement needs of different items and facilitate the retrieval of items.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
