Description

Technical Field

[0001] This invention relates to the technical field of pig torso fixation, and in particular to a pig torso wrapping fixation device. Background Technology

[0002] In pig farming, various procedures are frequently performed on pigs, such as vaccination, disease diagnosis and treatment, and sampling and testing. In scientific research, pigs are also often used for experimental procedures, such as monitoring physiological indicators and conducting drug trials. Effectively restraining the pigs and keeping them relatively still is crucial to ensuring the smooth execution of these procedures.

[0003] Currently, commonly used methods for restraining pigs have many drawbacks. For example, using simple rope bindings is not only ineffective, allowing pigs to easily struggle and escape, but also may damage the pig's skin and muscles if the bindings are too tight. In addition, some simple restraint frames have unreasonable structures that cannot be flexibly adjusted according to the size of the pig, resulting in unstable restraint. At the same time, the operation may cause stress to the pig, affecting its health and production performance. Therefore, developing a safe, effective, and comfortable pig torso restraint device is of great practical significance.

[0004] Currently, among devices for fixing the pig's torso, such as the prior art patent with publication number CN120053132A, the invention relates to the field of blood collection technology, specifically a small pig blood collection device for animal medical experiments, including a cage. The cage contains a torso clamping mechanism, a head clamping mechanism, and a mouth clamping mechanism arranged sequentially from the tail to the head along its own length direction. A linkage drive mechanism is provided on the inner side of the head of the cage, which is used to tighten the head clamping mechanism.

[0005] Existing devices, when used to fix the pig's torso, have a relatively fixed shape and size of clamping plates, which reduces the stability of the device for embracing and fixing pigs of different sizes and reduces the flexibility of use. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides a pig torso restraint device that tightens the lower and upper limiting bodies while simultaneously tightening the tightening band, thereby achieving a wrapping and fixing effect on the pig's torso, improving the fit of the wrapping and fixing, reducing the chance of the pig breaking free, facilitating the height adjustment of the lower limiting body, upper limiting body and tightening band, and improving the convenience of wrapping and fixing the torso of pigs of different body sizes.

[0007] The present invention provides a pig torso wrapping fixation device, comprising two sets of clamping mechanisms arranged opposite to each other; The clamping mechanism includes a support mechanism, a tensioning mechanism, a drive mechanism, a first support member, a first sliding member, a scissor structure, a lower limiting body, an upper limiting body, a tightening belt, and a second sliding member. The top end of the first support member is connected to the second sliding member, and the second sliding member is slidably mounted on the support mechanism. The support mechanism is used to drive the first support member to move and adjust. Two sets of first sliding members are slidably mounted on the first support member through the drive mechanism. The right end of the scissor structure is rotatably connected to the two sets of first sliding members. The lower limiting body is mounted on the lower left end of the scissor structure, and the upper limiting body is mounted on the scissor structure. At the upper left end of the fork structure, the bottom end of the tightening band is connected to the outer wall of the lower limiting body. The upper part of the tightening band slides through the interior of the upper limiting body and connects to the second sliding member. The tensioning mechanism is set on the first guide member and is used to tension and support the tightening band. The pig is driven and guided between the tightening bands of the two sets of clamping mechanisms. Then, the support mechanism drives the first support members on both sides to move closer to each other, so that the first support members on both sides drive the lower limiting body, upper limiting body and tightening band on both sides to move closer to each other, so that the lower limiting body and upper limiting body on both sides contact each other respectively. The lower limiting bodies on both sides are located below the pig's abdomen, and the upper limiting bodies on both sides are located above the pig's back. The tightening straps on both sides are located on the left and right sides of the pig's torso, pre-fixing the pig. Then, the drive mechanism drives the two sets of first sliding parts to move closer to each other, causing the two sets of first sliding parts to change the shape of the scissor structure and extend laterally. This causes the lower limiting body and the upper limiting body on both sides to move closer to each other. Since the lower limiting bodies and the upper limiting bodies on both sides are in contact with each other, when the scissor structure changes shape, it pushes the first sliding parts on both sides... The support components move away from each other. After the first support component moves, it drives the second sliding component to slide. At this time, the second sliding components on both sides pull the upper part of the tightening band on both sides, thereby tightening the lower limit body and the upper limit body while tightening the tightening band, achieving the effect of wrapping and fixing the pig's torso, improving the fit of the wrapping and fixing, and reducing the possibility of the pig struggling. The support mechanism drives the second sliding component to move up and down, which facilitates the adjustment of the height of the lower limit body, the upper limit body and the tightening band, improving the convenience of wrapping and fixing the torso of pigs of different sizes.

[0008] Preferably, the support mechanism includes a moving device, a first guide member, a second support member, a first telescopic rod, a spring, a second telescopic rod, and a first cylinder. Two sets of second sliding members are slidably mounted on two sets of first guide members, two sets of second support members are mounted on the bottom ends of two sets of first guide members, multiple sets of first telescopic rods are mounted on the outer walls of two sets of second support members, two sets of first support members are connected to the moving ends of multiple sets of first telescopic rods, multiple sets of springs are fitted onto multiple sets of first telescopic rods, the moving ends of multiple sets of second telescopic rods and multiple sets of first cylinders are connected to the top ends of two sets of first guide members, multiple sets of second telescopic rods and multiple sets of first cylinders are all mounted on the moving device, which is used to drive the second telescopic rods and first cylinders to move; the moving device drives the multiple sets of second telescopic rods and first cylinders on both sides. Multiple sets of first cylinders move in opposite directions, causing the second telescopic rod and the first cylinder to drive the first guide members on both sides to move closer to each other. After the two sets of first guide members move, they drive the two sets of first support members to move closer to each other, so that the lower limiting bodies on both sides contact each other, and at the same time, the upper limiting bodies on both sides contact each other. When the two sets of first sliding members move closer to each other, causing the scissor structure to deform and extend laterally, the contact support between the two sets of lower limiting bodies and the two sets of upper limiting bodies causes the two sets of scissor structure to support the two sets of first support members to move away from each other and compress the multiple sets of first telescopic rods and multiple sets of springs. At the same time, the first support members pull the two sets of tightening bands through the second sliding members, and the upper limiting body of the upper part and the lower limiting body of the lower part move closer to each other, thereby achieving the effect of tightening the pig's torso on all four sides at the same time.

[0009] Preferably, the device further includes an adjusting device, a base, a second guide, a second cylinder, two side limiting plates, and a third cylinder. The base is slidably mounted on the second guide. The second cylinder is mounted on the outer wall of the second guide, and its moving end is connected to the base. Two sets of upper and lower limiting plates are slidably mounted on the base, and two sets of side limiting plates are slidably mounted on the base. Multiple sets of third cylinders are mounted on the outer wall of the base, and their moving ends are connected to the upper and lower limiting plates and the side limiting plates, respectively. The base is mounted on the adjusting device, which is used to move and adjust the base. After the pig's torso is fixed, the adjusting device moves the base, causing the base to move the upper and lower limiting plates and the side limiting plates to the vicinity of the pig's head. Then, the multiple sets of third cylinders move the two sets of upper and lower limiting plates and the two sets of side limiting plates closer to each other, so that the two sets of upper and lower limiting plates and the two sets of side limiting plates cooperate to clamp and fix the pig's head, improving the stability of the pig's fixation.

[0010] Preferably, the tensioning mechanism includes a support roller, a support arm, a worm gear, a worm, and a first motor. The support roller is rotatably mounted on the front end of the support arm, and the rear end of the support arm is rotatably mounted on a first guide member. The worm gear is mounted on the rear end of the support arm, and the worm is rotatably mounted inside the first guide member and meshes with the worm gear. The first motor is mounted on the outer wall of the first guide member, and the output end of the first motor is connected to the worm. After the tensioning belt tightens and fixes the pig's torso, the first motor drives the worm to rotate, causing the worm to drive the support arm to rotate and swing through the worm gear. This causes the support arm to drive the support roller to move. After the support roller moves upward, it further tightens the tensioning belt. After the support roller moves downward, it loosens the tensioning belt, thereby increasing the tightening and fixing force on the pig and making it suitable for use on pigs of different sizes.

[0011] Preferably, the support mechanism includes a third guide member, a third sliding member, a first lead screw, and a second motor. Two sets of third sliding members are slidably mounted on the third guide member. Multiple sets of second telescopic rods and multiple sets of first cylinders are respectively mounted on the bottom ends of the two sets of third sliding members. The first lead screw is rotatably mounted inside the third guide member. The two sets of third sliding members are respectively screwed onto the first lead screw. The second motor is mounted on the outer wall of the third guide member, and the output end of the second motor is connected to the first lead screw. The second motor drives the first lead screw to rotate, causing the first lead screw to drive the two sets of third sliding members to move in opposite directions, thereby causing the lower limiting bodies, upper limiting bodies, and tightening belts on both sides to move and adjust in opposite directions.

[0012] Preferably, it also includes a platform and a through hole. The platform has a through hole at the top and a sewage outlet on the outer side wall. The platform is positioned between the clamping mechanisms on both sides. The pigs are driven and guided to the top of the platform, and then the pigs are wrapped and fixed, which improves the convenience of fixing the pigs. By setting the through hole, it is easy to collect the pigs' excrement into the platform, which improves the convenience of use.

[0013] Preferably, the system also includes a swinging component, a drain pipe, nozzles, and a third motor. The swinging component is rotatably mounted on the outer wall of the third guide component. The drain pipe is mounted on the outer wall of the swinging component and is connected to an external water supply device. Multiple nozzles are connected to the drain pipe. The third motor is mounted on the outer wall of the third guide component, and its output end is connected to the rotating end of the swinging component. Water is supplied to the drain pipe through the external water supply device, allowing multiple nozzles to rinse the top of the platform. This allows residual excrement on the top of the platform to enter the platform through the through-hole. The third motor drives the swinging component to swing back and forth, allowing multiple nozzles to rinse different positions on the platform.

[0014] Preferably, the adjusting device includes a fourth guide and a fourth cylinder. The second guide is slidably mounted on the fourth guide, and the fourth cylinder is mounted on the outer wall of the fourth guide. The moving end of the fourth cylinder is connected to the second guide. The second guide is moved by the fourth cylinder, which in turn moves the two side limit plates and the upper and lower limit plates to the vicinity of the pig's head, thereby improving the convenience of fixing the pig's head.

[0015] Preferably, it also includes steps, which are set on the side of the platform to improve the convenience for pigs to get on and off the platform.

[0016] Preferably, the driving mechanism includes a second lead screw and a fourth motor. The second lead screw is rotatably mounted on the inner side wall of the first support member, and two sets of first sliding members are screwed onto the second lead screw. The fourth motor is mounted on the outer side wall of the first support member, and the output end of the fourth motor is connected to the second lead screw. The second lead screw is rotated by the fourth motor, which drives the two sets of first sliding members to move in opposite directions.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The pig is driven and guided between the tightening straps of the two sets of clamping mechanisms. Then, the support mechanism drives the first support members on both sides to move closer to each other, causing the first support members on both sides to drive the lower limiting bodies, upper limiting bodies, and tightening straps on both sides to move closer to each other, bringing the lower limiting bodies and upper limiting bodies on both sides into contact. At this time, the lower limiting bodies on both sides are located below the pig's abdomen, the upper limiting bodies on both sides are located above the pig's back, and the tightening straps on both sides are located on the left and right sides of the pig's torso, thus pre-fixing the pig. Then, the drive mechanism drives the two sets of first sliding members to move closer to each other, causing the two sets of first sliding members to drive the scissor structure to change shape and extend laterally, thereby causing the scissor structure to drive the lower part... The limiting body moves closer to the upper limiting body. As the lower limiting bodies on both sides and the upper limiting bodies on both sides come into contact with each other, when the scissor structure changes shape, it pushes the first support members on both sides to move away from each other. After the first support members move, they drive the second sliding members to slide. At this time, the second sliding members on both sides pull the upper part of the tightening band on both sides, so that the lower limiting body and the upper limiting body tighten up and down while tightening the tightening band, achieving the effect of wrapping and fixing the pig's torso, improving the fit of the wrapping and fixing, and reducing the possibility of the pig struggling. The second sliding members are adjusted by the support mechanism to move up and down, which facilitates the height adjustment of the lower limiting body, the upper limiting body and the tightening band, and improves the convenience of wrapping and fixing the torso of pigs of different body sizes.

Detailed Implementation

[0020] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0021] Example 1 The present invention provides a pig torso wrapping fixation device, comprising two sets of clamping mechanisms arranged opposite to each other; The clamping mechanism includes a support mechanism, a tensioning mechanism, a drive mechanism, a first support member 101, a first sliding member 102, a scissor structure 103, a lower limiting body 104, an upper limiting body 105, a tightening strap 106, and a second sliding member 107. The top end of the first support member 101 is connected to the second sliding member 107. The second sliding member 107 is slidably mounted on the support mechanism, and the support mechanism is used to drive the first support member 101 to move and adjust. Two sets of first sliding members 102 are slidably mounted on the first support member 101 via the drive mechanism. On the support member 101, the right end of the scissor structure 103 is rotatably connected to two sets of first sliding members 102. The lower limiting body 104 is installed on the lower left end of the scissor structure 103, and the upper limiting body 105 is installed on the upper left end of the scissor structure 103. The bottom end of the tightening band 106 is connected to the outer wall of the lower limiting body 104. The upper part of the tightening band 106 slides through the interior of the upper limiting body 105 and is connected to the second sliding member 107. The tensioning mechanism is set on the first guide member 201 and is used to tighten and support the tightening band 106. The support mechanism includes a moving device, a first guide member 201, a second support member 203, a first telescopic rod 204, a spring 205, a second telescopic rod 206, and a first cylinder 207. Two sets of second sliding members 107 are slidably mounted on the two sets of first guide members 201, two sets of second support members 203 are mounted on the bottom ends of the two sets of first guide members 201, multiple sets of first telescopic rods 204 are mounted on the outer side walls of the two sets of second support members 203, the two sets of first support members 101 are connected to the moving ends of the multiple sets of first telescopic rods 204, multiple sets of springs 205 are fitted onto the multiple sets of first telescopic rods 204, the moving ends of the multiple sets of second telescopic rods 206 and the multiple sets of first cylinders 207 are connected to the top ends of the two sets of first guide members 201, and the multiple sets of second telescopic rods 206 and the multiple sets of first cylinders 207 are all mounted on the moving device, which is used to drive the second telescopic rods 206 and the first cylinders 207 to move. In this embodiment, the pig is driven and guided between the tightening straps 106 of the two sets of clamping mechanisms. Then, the support mechanism drives the first support members 101 on both sides to move closer to each other, causing the first support members 101 on both sides to drive the lower limiting bodies 104, upper limiting bodies 105 and tightening straps 106 on both sides to move closer to each other, so that the lower limiting bodies 104 and upper limiting bodies 105 on both sides respectively come into contact. At this time, the lower limiting bodies 104 on both sides are located below the pig's abdomen, the upper limiting bodies 105 on both sides are located above the pig's back, and the tightening straps 106 on both sides are located on the left and right sides of the pig's torso, so that the pig is pre-fixed. Then, the drive mechanism drives the two sets of first sliding members 102 to move closer to each other, causing the two sets of first sliding members 102 to drive the scissor structure 103 to change shape and extend laterally, so that the scissor structure 103 drives the lower limiting body 104 to contact the upper limiting body 105. The upper limiting bodies 105 of the scissor structure move closer to each other. Since the lower limiting bodies 104 and the upper limiting bodies 105 on both sides are in contact with each other, when the scissor structure 103 changes shape, it pushes the first support members 101 on both sides to move away from each other. After the first support members 101 move, they drive the second sliding members 107 to slide. At this time, the second sliding members 107 on both sides pull the upper part of the tightening bands 106 on both sides, so that the lower limiting bodies 104 and the upper limiting bodies 105 tighten up and down while tightening the tightening bands 106, thereby achieving the effect of circling and fixing the pig's torso, improving the fit of the circling and fixing, and reducing the possibility of the pig breaking free. The second sliding members 107 are moved up and down by the support mechanism to adjust the height of the lower limiting bodies 104, the upper limiting bodies 105 and the tightening bands 106, thereby improving the convenience of circling and fixing the torso of pigs of different body sizes.

[0022] Example 2 Based on Embodiment 1, the present invention provides a pig torso encircling fixation device, which further includes an adjustment device, a base 301, a second guide 302, a second cylinder 303, two side limiting plates 305, and a third cylinder 306. The base 301 is slidably mounted on the second guide 302. The second cylinder 303 is mounted on the outer side wall of the second guide 302, and the moving end of the second cylinder 303 is connected to the base 301. Two sets of upper and lower limiting plates 304 are slidably mounted on the base 301, and two sets of side limiting plates 305 are slidably mounted on the base 301. Multiple sets of third cylinders 306 are mounted on the outer side wall of the base 301, and the moving ends of the multiple sets of third cylinders 306 are connected to the upper and lower limiting plates 304 and the side limiting plates 305, respectively. The base 301 is mounted on the adjustment device, which is used to drive the base 301 to move and adjust. The support mechanism includes a third guide 501, a third sliding member 502, a first lead screw 503, and a second motor 504. Two sets of third sliding members 502 are slidably mounted on the third guide 501. Multiple sets of second telescopic rods 206 and multiple sets of first cylinders 207 are respectively mounted on the bottom ends of the two sets of third sliding members 502. The first lead screw 503 is rotatably mounted inside the third guide 501. The two sets of third sliding members 502 are respectively screwed onto the first lead screw 503. The second motor 504 is mounted on the outer wall of the third guide 501. The output end of the second motor 504 is connected to the first lead screw 503. It also includes a platform 601 and a through hole 602. The top of the platform 601 is provided with a through hole 602, and the outer wall of the platform 601 is provided with a drain outlet. The platform 601 is located between the clamping mechanisms on both sides. It also includes a swinging component 701, a drain pipe 702, a nozzle 703, and a third motor 704. The swinging component 701 is rotatably mounted on the outer wall of the third guide component 501. The drain pipe 702 is mounted on the outer wall of the swinging component 701 and is connected to an external water supply device. Multiple sets of nozzles 703 are connected to the drain pipe 702. The third motor 704 is mounted on the outer wall of the third guide component 501, and the output end of the third motor 704 is connected to the rotating end of the swinging component 701. The adjustment device includes a fourth guide 801 and a fourth cylinder 802. The second guide 302 is slidably mounted on the fourth guide 801. The fourth cylinder 802 is mounted on the outer wall of the fourth guide 801. The moving end of the fourth cylinder 802 is connected to the second guide 302. It also includes step 901, which is located on the side of platform 601; The drive mechanism includes a second lead screw 1001 and a fourth motor 1002. The second lead screw 1001 is rotatably mounted on the inner side wall of the first support member 101. Two sets of first sliding members 102 are screwed onto the second lead screw 1001. The fourth motor 1002 is mounted on the outer side wall of the first support member 101. The output end of the fourth motor 1002 is connected to the second lead screw 1001. In this embodiment, a moving device drives multiple sets of second telescopic rods 206 and multiple sets of first cylinders 207 on both sides to move in opposite directions. This causes the second telescopic rods 206 and first cylinders 207 to drive the first guide members 201 on both sides to move closer to each other. After the two sets of first guide members 201 move, they drive the two sets of first support members 101 to move closer to each other, thereby making the lower limiting bodies 104 on both sides contact each other, and at the same time, making the upper limiting bodies 105 on both sides contact each other. When the two sets of first sliding members 102 move closer to each other, causing the scissor structure 103 to deform and extend laterally, the contact support between the two sets of lower limiting bodies 104 and the two sets of upper limiting bodies 105 allows the two sets of scissor structures 103 to support the two sets of first support members 101 to move away from each other and move the multiple sets of first telescopic rods 206 and first cylinders 207 towards each other. The rod 204 and multiple sets of springs 205 are compressed, while the first support member 101 pulls the two sets of tightening straps 106 through the second sliding member 107. The upper limit body 105 and the lower limit body 104 move closer to each other, thereby achieving a simultaneous tightening effect on all four sides of the pig's torso. After the pig's torso is fixed, the base 301 is moved by the adjustment device, causing the base 301 to move the upper and lower limit plates 304 and the side limit plates 305 to the four sides of the pig's head. Then, multiple sets of third cylinders 306 respectively drive the two sets of upper and lower limit plates 304 and the two sets of side limit plates 305 to move closer to each other, so that the two sets of upper and lower limit plates 304 and the two sets of side limit plates 305 cooperate to clamp and fix the pig's head, improving the stability of the pig's fixation.

[0023] Example 3 Based on Embodiment 1, the present invention provides a pig torso wrapping fixation device, wherein the tensioning mechanism includes a support roller 401, a support arm 402, a worm gear 403, a worm 404, and a first motor 405. The support roller 401 is rotatably mounted on the front end of the support arm 402, and the rear end of the support arm 402 is rotatably mounted on a first guide member 201. The worm gear 403 is mounted on the rear end of the support arm 402, and the worm 404 is rotatably mounted inside the first guide member 201 and meshes with the worm gear 403. The first motor 405 is mounted on the first guide member 201. On the outer side wall, the output end of the first motor 405 is connected to the worm gear 404; after the tightening belt 106 tightens and fixes the pig's torso, the first motor 405 drives the worm gear 404 to rotate, causing the worm gear 404 to drive the support arm 402 to rotate and swing through the worm wheel 403, causing the support arm 402 to drive the support roller 401 to move. After the support roller 401 moves upward, it further tightens the tightening belt 106. After the support roller 401 moves downward, it loosens the tightening belt 106, increasing the tightening and fixing force on the pig, making it easier to adapt to pigs of different sizes.

[0024] like Figures 1 to 10As shown, the present invention discloses a pig torso wrapping restraint device. During operation, the pig is driven and guided between the tightening straps 106 of two sets of clamping mechanisms. Then, a support mechanism drives the first support members 101 on both sides to move closer together, causing the lower limiting bodies 104, upper limiting bodies 105, and tightening straps 106 on both sides to move closer together, bringing the lower limiting bodies 104 and upper limiting bodies 105 into contact. At this point, the lower limiting bodies 104 are located below the pig's abdomen, the upper limiting bodies 105 are located above the pig's back, and the tightening straps 106 are located on the left and right sides of the pig's torso, thus pre-fixing the pig. Then, a drive mechanism drives the two sets of first sliding members 102 to move closer together. The movement causes the two sets of first sliding members 102 to drive the scissor structure 103 to change shape and extend laterally. This causes the scissor structure 103 to move closer to the lower limiting body 104 and the upper limiting body 105. Since the lower limiting bodies 104 and the upper limiting bodies 105 on both sides are in contact with each other, when the scissor structure 103 changes shape, it pushes the first support members 101 on both sides to move away from each other. After the first support members 101 move, they drive the second sliding members 107 to slide. At this time, the second sliding members 107 on both sides pull the upper part of the tightening bands 106 on both sides, thereby tightening the lower limiting body 104 and the upper limiting body 105 vertically and simultaneously tightening the tightening bands 106, achieving a circumferential fixation effect on the pig's torso.

[0025] The main functions achieved by this invention are: 1. The lower limiting bodies 104 on both sides are located below the abdomen of the pig, the upper limiting bodies 105 on both sides are located above the back of the pig, and the tightening straps 106 on both sides are located on the left and right sides of the pig's torso, so as to pre-fix the pig. 2.
