Technical Field

[0001] This utility model relates to the field of farrowing pen technology, and in particular to an adjustable partition farrowing pen for sows. Background Technology

[0002] A farrowing crate, also known as a sow farrowing pen or piglet farrowing bed, is a specialized piece of equipment designed specifically for the sow's farrowing and piglet nursing stages. It typically consists of a sow gestation crate, piglet protection crates, piglet warming boxes, slatted flooring, sow feed troughs and piglet supplemental feed troughs, sow waterers and piglet waterers, etc. The main function of the farrowing crate is to provide an environment conducive to timely and measured feeding of the sow, reducing feed waste, controlling the sow's body condition, and facilitating lactation and piglet nursing. Simultaneously, it ensures that piglets have a safe and comfortable space to move around, preventing the sow from trampling, crushing, or killing piglets, thus reducing the intensity of manual labor.

[0003] In traditional farrowing pens, partitioned pens are typically fixed to the farrowing pen by welding. While this design is simple, it makes it difficult to adjust to different sow sizes. Different breeds of sows have varying body sizes, and fixed partitioned pens often cannot accommodate all sows, restricting their movement space. Therefore, an adjustable partitioned farrowing pen is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide an adjustable partition sow farrowing pen to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides an adjustable-partition sow farrowing pen, including a base frame. A support plate is fixedly connected to the top surface of the base frame. A bidirectional lead screw is rotatably connected to the inside of the base frame via bearings. Two symmetrically arranged drive plates are threaded onto the outer surface of the bidirectional lead screw. Both drive plates are slidably connected to the base frame. Two symmetrically arranged connecting plates are fixedly connected to the top surface of each drive plate. Both connecting plates are slidably connected to the base frame. A movable plate is fixedly connected to the top of each connecting plate. Two symmetrically arranged T-shaped clamps are fixedly connected to the bottom surface of each movable plate. Both T-shaped clamps are slidably connected to the base frame. A U-shaped guardrail is connected to the top surface of each movable plate. A partition fence is fixedly connected to the side of the U-shaped guardrail closest to the support plate. The support plate is located between the two partition fences. Two symmetrically arranged guardrail doors are hung between the two partition fences. The partition fences and guardrail doors are perpendicular to the base frame.

[0007] Preferably, in any of the above solutions, two symmetrically arranged guide rods are fixedly connected to the inner wall of the bottom frame, the bidirectional lead screw is located between the two guide rods, and both drive plates are slidably connected to the guide rods.

[0008] Preferably, in any of the above embodiments, the bottom surface of the movable plate is fixedly connected to a plurality of linear array rotating frames, each of the rotating frames having a roller rotatably connected inside, and the plurality of rollers being slidably connected to the bottom frame.

[0009] Preferably, in any of the above embodiments, a threaded sleeve is fixedly connected to the side of the movable plate away from the bearing plate, and a locking bolt is threadedly connected to the inner wall of the threaded sleeve, with the bottom end of the locking bolt abutting against the top surface of the bottom frame.

[0010] Preferably, the top surface of the bottom frame is provided with a plurality of symmetrically arranged connecting grooves, and the plurality of connecting plates are slidably connected to the bottom frame through the plurality of connecting grooves.

[0011] Preferably, the top surface of the bearing plate is provided with a plurality of symmetrically arranged T-shaped slots, and the T-shaped slots are slidably connected to the bottom frame through the T-shaped slots.

[0012] Preferably, in any of the above embodiments, extension plates are fixedly connected to both the left and right sides of the bearing plate, both extension plates are parallel to the bottom frame, and the two extension plates are slidably connected to the two movable plates respectively.

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

[0014] 1. When using a farrowing crate, the staff first needs to move the base frame to the desired position and fix it to the ground with bolts. Then, measure the size of the sow to be farrowed. Twist the control wheel on the outside of the base frame to drive the bidirectional screw to rotate relative to the base frame. Through threaded transmission, the two drive plates can move in opposite directions. At this time, the drive plates will slide relative to the guide rod, which can guide the movement of the drive plates and make their sliding inside the base frame more stable. Through the transmission of the connecting plate, the two moving plates can be driven to move in opposite directions until the distance between the two partition pens is adapted to the size of the sow. At this time, turn the locking bolt to rotate it inside the threaded sleeve until the bottom surface of the locking bolt is in contact with the top surface of the base frame. The moving plates can be locked, which improves the connection stability between the moving plates and the base frame. Finally, drive the sow into the space between the two partition pens and use a fence gate of appropriate length to seal the front and rear ends of the partition pens. The distance between the partition pens can be adjusted according to the size of different breeds of sows.

[0015] 2. As the movable plate moves, it can drive several rollers to roll on the top surface of the bottom frame. This supports the movable plate and reduces the friction between it and the bottom frame, making it easier to control the movement of the movable plate. As the movable plate moves, it will slide relative to the extension plate, which can prevent pits from forming between the movable plate and the support plate, making it easier for piglets to move into the U-shaped guardrail. As the movable plate moves, it will drive the T-shaped card plate to slide inside the T-shaped card slot, which can limit the range of motion of the movable plate. Attached Figure Description

A bidirectional lead screw 3 is rotatably connected to the inside of the base frame 1 via bearings. Two symmetrically arranged drive plates 4 are threadedly connected to the outer surface of the bidirectional lead screw 3. Both drive plates 4 are slidably connected to the base frame 1. Two symmetrically arranged connecting plates 5 are fixedly connected to the top surface of each drive plate 4. Both connecting plates 5 are slidably connected to the base frame 1. A movable plate 6 is fixedly connected to the top of each connecting plate 5. Two symmetrically arranged T-shaped clamps 7 are fixedly connected to the bottom surface of each movable plate 6. Both T-shaped clamps 7 are slidably connected to the base frame 1. A U-shaped guardrail 8 is connected to the top surface of each movable plate 6. A partition fence 9 is fixedly connected to the side of the U-shaped guardrail 8 closest to the support plate 2. The support plate 2 is located between the two partition fences 9. Two symmetrically arranged guardrail doors 10 are hung between the two partition fences 9. The partition fences 9 and the guardrail doors 10 are perpendicular to the base frame 1.

[0024] As an optional technical solution of this utility model, two symmetrically arranged guide rods 11 are fixedly connected to the inner wall of the bottom frame 1. A bidirectional lead screw 3 is located between the two guide rods 11. Both drive plates 4 are slidably connected to the guide rods 11. The drive plates 4 will slide relative to the guide rods 11, which can guide the movement of the drive plates 4 and make it slide more stably inside the bottom frame 1. While the moving plate 6 is moving, it can drive several rollers 13 to roll on the top surface of the bottom frame 1. While supporting the moving plate 6, it reduces the friction between the moving plate 6 and the bottom frame 1, which can make it easier to control the movement of the moving plate 6.

[0025] As an optional technical solution of this utility model, the bottom surface of the movable plate 6 is fixedly connected with a number of linear array rotating frames 12, and each rotating frame 12 is rotatably connected to a roller 13 inside, and the rollers 13 are all slidably connected to the bottom frame 1.

[0026] As an optional technical solution of this utility model, a threaded sleeve 14 is fixedly connected to the side of the movable plate 6 away from the bearing plate 2, and a locking bolt 15 is threadedly connected to the inner wall of the threaded sleeve 14. The bottom end of the locking bolt 15 is in contact with the top surface of the bottom frame 1.

[0027] As an optional technical solution of this utility model, the top surface of the bottom frame 1 is provided with a number of symmetrically arranged connecting grooves 16, and a number of connecting plates 5 are slidably connected to the bottom frame 1 through the connecting grooves 16. The connecting plates 5 can drive two moving plates 6 to move towards each other until the distance between the two partition pens 9 is adapted to the body size of the sow. The distance between the partition pens 9 can be adjusted according to the body size of different breeds of sows.

[0028] As an optional technical solution of this utility model, the top surface of the support plate 2 is provided with a number of symmetrically arranged T-shaped slots 17. The T-shaped card plate 7 is slidably connected to the bottom frame 1 through the T-shaped slots 17.

[0029] As an optional technical solution of this utility model, extension plates 18 are fixedly connected to both the left and right sides of the bearing plate 2. Both extension plates 18 are parallel to the bottom frame 1. The two extension plates 18 are slidably connected to two movable plates 6 respectively. When the movable plates 6 move, they will slide relative to the extension plates 18, which can prevent pits from appearing between the movable plates 6 and the bearing plate 2, and facilitate the piglets to move into the U-shaped guardrail 8.

[0030] An adjustable-partition farrowing crate for sows works as follows:

[0031] 1) When a farrowing pen is needed, the staff first need to move the base frame 1 to the position of use and fix the base frame to the ground with bolts. Then, the size of the sow to be farrowed is measured. The control wheel on the outside of the base frame 1 is turned to drive the bidirectional screw 3 to rotate relative to the base frame 1. Through the threaded transmission, the two drive plates 4 can be driven to move in opposite directions.

[0032] 2): The two moving plates 6 can be driven to move in opposite directions through the transmission of the connecting plate 5 until the distance between the two partition pens 9 is adapted to the body size of the sow. At this time, the locking bolt 15 is turned to rotate inside the threaded sleeve 14 until the bottom surface of the locking bolt 15 is in contact with the top surface of the bottom frame 1.

[0033] 3): Drive the sow into the space between the two partition pens 9, and use a fence gate 10 of appropriate length to seal the front and back ends of the partition pens 9. The spacing between the partition pens 9 can be adjusted according to the size of different breeds of sows.

[0034] In summary, when using this adjustable-partition farrowing pen, the operator first needs to move the base frame 1 to the desired position and secure it to the ground with bolts. Then, the size of the sow to be farrowed is measured. Twisting the control wheel on the outer side of the base frame 1 rotates the bidirectional lead screw 3 relative to the base frame 1. Through threaded transmission, this drives two drive plates 4 to move in opposite directions. At this time, the drive plates 4 will slide relative to the guide rod 11, guiding their movement and making them slide more stably within the base frame 1. Through the transmission of the connecting plate 5, two moving plates 6 can be driven to move in opposite directions until the distance between the two partition pens 9 matches the sow's size. Then, the locking bolt 15 is twisted to rotate within the threaded sleeve 14 until the bottom surface of the locking bolt 15 is in contact with the top surface of the base frame 1. Yes, the movable plate 6 can be locked, which improves the connection stability between the movable plate 6 and the bottom frame 1. Finally, the sow is driven into the space between the two partition pens 9, and the front and rear ends of the partition pens 9 are sealed with guardrail gates 10 of appropriate length. The spacing between the partition pens 9 can be adjusted according to the body size of different breeds of sows. While the movable plate 6 is moving, it can drive several rollers 13 to roll on the top surface of the bottom frame 1, which reduces the friction between the movable plate 6 and the bottom frame 1 while supporting the movable plate 6, making it easier to control the movement of the movable plate 6. While the movable plate 6 is moving, it will slide relative to the extension plate 18, which can prevent pits from appearing between the movable plate 6 and the bearing plate 2, making it easier for piglets to move into the U-shaped guardrail 8. While the movable plate 6 is moving, it will drive the T-shaped card plate 7 to slide inside the T-shaped card slot 17, which can limit the range of movement of the movable plate 6.
