Description

Technical Field

[0001] This invention relates to the field of animal husbandry technology, and in particular to a mating assistance device for breeding pigs. Background Technology

[0002] Livestock and poultry farming is an important industry in my country's agriculture, with pig farming accounting for a large proportion. Pig farming not only requires ensuring daily feeding and disease prevention, but also the breeding and mating of pigs. Currently, mating operations are carried out in specialized breeding pens, and artificial assistance is needed to enable breeding pigs to mate.

[0003] The existing methods of artificially assisted breeding of pigs usually involve first releasing the sow from the pen, then leading her to a separate mating room, and then releasing the boar from the pen and leading him to the mating room as well. When the boar is in heat, he will mate with the sow on his own.

[0004] During mating, to prevent the sow from escaping and hindering successful mating, manual intervention is usually required. The sow needs to be restrained and controlled. However, pigs are relatively large compared to humans, making it difficult for one or two people to completely control them. The current method involves first pushing the sow into an enclosure to confine her, and then allowing the boar to mate with her. This prevents the sow from escaping and hindering mating. However, sometimes the sow resists strongly when being pushed into the enclosure, making it difficult for staff to do so. This is time-consuming and laborious, making the entire mating process more challenging. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as difficulty for workers to push sows into the pen, which is time-consuming and laborious, and makes the entire mating process of breeding pigs difficult. Therefore, this invention proposes a breeding pig mating assistance device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a breeding pig mating assistance device, including an induction mechanism, which is disposed inside an outer shell for breeding pig mating, and the induction mechanism is used to induce sows to enter the outer shell;

[0008] The inducing mechanism includes a support platform, a belt conveyor, and an enticing box. The support platform is fixedly connected inside the outer shell, the belt conveyor is embedded in the middle of the support platform, and the enticing box is disposed on the upper surface of the belt conveyor.

[0009] Preferably, an anti-running mechanism is provided on one side of the outer shell. The anti-running mechanism is used to prevent the sow from running out of the outer shell. The anti-running mechanism includes a first motor, a baffle, a first spur rack, and a first gear. The first motor is fixedly connected to the outer shell. The baffle is slidably disposed on one side of the outer shell. The first spur rack is fixedly connected to one side of the baffle. The first gear is rotatably connected to the outer shell and meshes with the first spur rack. One end of the output shaft of the first motor is fixedly connected to the first gear.

[0010] Preferably, the housing is provided with a synchronization mechanism, which is disposed between the first gear and the belt conveyor to drive the belt conveyor to run synchronously. The synchronization mechanism includes a second gear, a third gear, and a fourth gear. The second gear is rotatably connected to the housing and meshes with the first gear. The third gear is rotatably connected to the housing and meshes with the second gear. The fourth gear is rotatably connected to the housing and meshes with the third gear. The fourth gear is fixedly connected to one of the pulleys of the belt conveyor.

[0011] Preferably, the interior of the housing is provided with two anti-collision mechanisms, and the two anti-collision mechanisms are respectively connected to both sides of the upper surface of the support platform. The anti-collision mechanism includes several springs, anti-collision plates and openings. The several springs are arranged in two rows and are respectively fixedly connected to the top of the inner wall of the housing and the upper surface of the support platform. The anti-collision plates are fixedly connected between the two rows of springs, and the openings are opened through the anti-collision plates.

[0012] Preferably, a body elevation mechanism is provided on both sides of the upper surface of the support platform, and the two body elevation mechanisms are arranged opposite to each other. The body elevation mechanism includes a one-way propulsion mechanism, a lifting mechanism, and a support assembly. The one-way propulsion mechanism is located on one side of the second gear, the lifting mechanism is located on the side of the one-way propulsion mechanism away from the baffle, and the support assembly is connected to one side of the lifting mechanism and is located on the upper surface of the support platform.

[0013] Preferably, the unidirectional propulsion mechanism includes a second spur rack, a first spring rod, a ring gear, an inner ring ratchet, a limiting tooth, and a second motor. One end of the second spur rack is slidably mounted on the inner sidewall of the housing via the first spring rod. The ring gear is rotatably connected to the housing, and the second spur rack meshes with the upper end of the ring gear. The inner ring ratchet is fixedly connected to one side of the second gear, and the ring gear is located on one side of the inner ring ratchet. The limiting tooth is rotatably connected to one side of the ring gear, and the limiting tooth is engaged in the inner ring ratchet. The second motor is fixedly connected to the other side of the ring gear, and one end of the output shaft of the second motor is fixedly connected to the limiting tooth.

[0014] Preferably, the lifting mechanism includes a connecting column, a second spring rod, a third rack and a toothed roller. The connecting column is slidably mounted on the inner wall of the housing via the second spring rod. The third rack is fixedly connected to one side of the connecting column. The toothed roller is rotatably connected to the inner wall of the housing, and the third rack meshes with the toothed roller. The support assembly is fixedly connected to one side of the connecting column.

[0015] Preferably, the support assembly includes a connecting frame and a plurality of support bars. The connecting frame is fixedly connected to one side of the connecting column and slides through the opening. The plurality of support bars are fixedly connected to the connecting frame at equal intervals, and the plurality of support bars are all located on the upper surface of the support platform.

[0016] Preferably, the baffle is further provided with a one-way limiting mechanism, which includes a notch, a movable plate and several limiting rods. The notch is opened through the baffle, the upper end of the movable plate is hinged to the side of the notch near the support platform, and the several limiting rods are fixedly connected to both sides of the movable plate in two rows.

[0017] The beneficial effects of the assisted mating device for breeding pigs proposed in this invention are as follows:

[0018] 1. This breeding pig mating assistance device, through the setting of the induction mechanism, can easily lure the sow into the shell, thus pre-confining the sow inside. Moreover, during the process of confining the sow, there is no need for staff to spend time and effort pushing the sow into the mating room. Under the lure of the feeding box, the sow will actively follow the feeding box into the shell, which makes the mating process between the boar and the sow more convenient. Furthermore, because the sow is confined by the shell, it is difficult for her to break free and resist, thus making the mating process of the breeding pigs more convenient and stable.

[0019] 2. With the anti-runaway mechanism, when the sow is completely lured into the shell by the feeding box, the baffle will close the entrance of the shell, thus easily confining the sow completely inside the shell. This can prevent the sow from being startled and running out of the shell in case of an emergency, which would be difficult to handle. It can also make the subsequent mating process between the boar and the sow more favorable.

[0020] 3. With the one-way limiting mechanism, since the movable plate is hinged to the inside of the shell and under the action of several limiting rods, pigs can enter the shell from the outside but cannot run out of the shell from the inside. Thus, on the one hand, it facilitates boars to enter the shell from the outside, and on the other hand, it prevents sows from running out of the shell from the inside.

[0021] 4. By setting up a synchronization mechanism, the opening and closing process of the baffle and the movement process of the feeding box can be carried out simultaneously. As the sow gradually walks into the shell, the baffle gradually closes downwards, thus ensuring that the sow can be successfully and easily lured into the shell and restrained, preventing the sow from running away midway.

[0022] 5. Through the setting of the anti-collision mechanism, under the action of several springs and anti-collision plates, the sides of the sow can be blocked. When a sudden situation occurs and the sow is frightened and rushes back and forth, several springs and anti-collision plates can play an anti-collision role and achieve a certain buffering effect. This not only prevents the sow from rushing back and forth and causing injury to herself, but also prevents the sow from damaging the parts in the equipment.

[0023] 6. The body-lifting mechanism allows the sow to be easily lifted once she is fully inside the enclosure, thus elevating her position. This elevates the sow, preventing excessive struggling or collisions and facilitating mating. Furthermore, because the sow is smaller than the boar, elevating her position allows for better contact between her and the boar's reproductive organs, further facilitating mating.

Detailed Implementation

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] Example 1

[0041] Reference Figure 1-2 A breeding pig mating assistance device includes an induction mechanism, which is disposed inside a shell 1 for breeding pig mating and is used to induce sows to enter the shell 1.

[0042] The induction mechanism includes a support platform 2, a conveyor belt 3, and a feed box 4. The support platform 2 is fixedly connected inside the outer shell 1 and is used to support the breeding pigs. When the sow and boar mate inside the outer shell 1, they will stand on the support platform 2. The conveyor belt 3 is embedded in the middle of the support platform 2. When the breeding pigs mate, the sow and boar stand on both sides of the upper surface of the support platform 2 with their limbs straddling the conveyor belt 3. The feed box 4 is set on the upper surface of the conveyor belt 3. The feed box 4 can be placed directly on the conveyor belt 3 or it can be fixedly connected to the conveyor belt 3. The feed box 4 contains feed that the breeding pigs like to eat.

[0043] During the breeding process, the sow is first released from the pen and then led to the equipment. Next, the conveyor belt 3 moves the feed attractant box 4 to the entrance of the outer shell 1. The sow, attracted by the feed in the box 4, enters the outer shell 1. Then, the conveyor belt 3 moves the feed attractant box 4 back to its initial position, ensuring the sow is fully inside the outer shell 1. Inside, the sow is led to the support platform 2 by the feeding box 4. Eventually, the sow will eat the feed peacefully inside the shell 1. At this time, the boar is released from the pen and led to the equipment. Since the breeding pigs are in estrus and mating season, the boar will go into heat when it sees the sow inside the shell 1. The boar will then walk into the shell 1 on its own and actively mate with the sow. The sow is now confined inside the shell 1 and cannot break free or resist, which makes the mating process between the sow and the boar more convenient. Therefore, by setting up the induction mechanism, the sow can be easily lured into the outer shell 1, thus pre-restricting the sow inside the outer shell 1. Moreover, during the process of restricting the sow, there is no need for staff to spend time and effort pushing the sow into the mating room. Under the lure of the feeding box 4, the sow will actively follow the feeding box 4 into the outer shell 1, which makes the mating process between the boar and the sow more convenient. Furthermore, since the sow is restricted by the outer shell 1, it is difficult for her to break free and resist, which makes the mating process of the breeding pigs more convenient and stable.

[0044] Example 2

[0045] Reference Figure 1-6 As another preferred embodiment of the present invention, the difference from embodiment 1 is that an anti-running mechanism 5 is provided on one side of the outer shell 1. The anti-running mechanism 5 is used to prevent the sow from running out of the outer shell 1. The anti-running mechanism 5 includes a first motor 51, a baffle 52, a first straight rack 53 and a first gear 54. The first motor 51 is fixedly connected to the outer shell 1. The first motor 51 is connected to an external power supply device through a wire, and a switch for controlling the operation of the first motor 51 is provided on the wire. The first motor 51 is a servo motor.

[0046] A baffle 52 is slidably disposed on one side of the outer casing 1. A first rack 53 is fixedly connected to one side of the baffle 52. A first gear 54 is rotatably connected to the outer casing 1, and the first gear 54 meshes with the first rack 53. One end of the output shaft of the first motor 51 is fixedly connected to the first gear 54. By starting the first motor 51, the first motor 51 drives the first gear 54 to rotate, which in turn drives the first rack 53 to move upward. The rack 53 then drives the baffle 52 to move upward. When the baffle 52 is fully open, the feeding box 4 is moved to the baffle 52 by adjusting the belt conveyor 3. The sow can then be lured into the outer shell 1. The conveyor belt 3 is then adjusted to move the feeding box 4 back to its initial position, allowing the sow to follow it into the outer shell 1. Once the sow is fully inside, the first motor 51 is reversed, causing the first gear 54 to rotate in the opposite direction. This, in turn, moves the first rack 53 downwards, which in turn moves the baffle 52 downwards until it is completely closed. At this point, the sow is completely confined within the outer shell 1 and cannot escape. Therefore, by implementing the anti-escape mechanism 5, when the sow is fully lured into the outer shell 1 by the feeding box 4, the baffle 52 closes the entrance to the outer shell 1, effectively confining the sow inside. This prevents the sow from being startled and escaping in a sudden situation, thus facilitating the subsequent mating process between the boar and the sow.

[0047] The baffle 52 is also equipped with a one-way limiting mechanism 58, which includes a notch 581, a movable plate 582, and several limiting rods 583. The notch 581 is opened through the baffle 52. The upper end of the movable plate 582 is hinged to the side of the notch 581 near the support platform 2. Several limiting rods 583 are fixedly connected to the two sides of the movable plate 582 in two rows. When the sow has been confined inside the shell 1 and the baffle 52 is in the closed state, the boar can be released to mate with the sow. At this time, the staff needs to manually rotate and push the movable plate 582 upward. When the boar sees the sow inside the shell 1, it will actively enter the shell 1 to mate with the sow. Therefore, by setting up the one-way limiting mechanism 58, since the movable plate 582 is hinged to the inside of the outer shell 1, and under the action of several limiting rods 583, pigs can enter the outer shell 1 from the outside, but cannot run out of the outer shell 1 from the inside. Thus, on the one hand, it is convenient for boars to enter the outer shell 1 from the outside, and on the other hand, it can prevent sows from running out of the outer shell 1 from the inside.

[0048] Example 3

[0049] Reference Figure 3-8As another preferred embodiment of the present invention, the difference from embodiment 2 is that a synchronization mechanism is provided on the outer casing 1. The synchronization mechanism is located between the first gear 54 and the belt conveyor 3 for driving the belt conveyor 3 to run synchronously. The synchronization mechanism includes a second gear 55, a third gear 56 and a fourth gear 57. The second gear 55 is rotatably connected to the outer casing 1 and meshes with the first gear 54. The third gear 56 is rotatably connected to the outer casing 1 and meshes with the second gear 55. The fourth gear 57 is rotatably connected to the outer casing 1 and meshes with the third gear 56. The fourth gear 57 is fixedly connected to one of the pulleys in the belt conveyor 3.

[0050] During the process of opening the baffle 52 upwards by activating the first motor 51, the first motor 51 drives the first gear 54 to rotate, which in turn drives the second gear 55 to rotate. The second gear 55 then drives the third gear 56 to rotate, which in turn drives the fourth gear 57 to rotate. The fourth gear 57 then drives one of the pulleys in the belt conveyor 3 to rotate. This allows the belt conveyor 3 to move the bait box 4 to the entrance of the outer shell 1. Throughout this process, as the baffle 52 gradually opens upwards, the bait box 4 moves synchronously towards the entrance of the outer shell 1. When the baffle 52 is fully open, the bait box 4 has just moved to the entrance of the outer shell 1. At this point, the sow can be lured in. As the sow follows the bait box 4 into the outer shell 1, the first motor 51 is simultaneously reversed. Conversely, as the baffle 52 gradually closes downwards, the bait box 4 moves back towards its initial position. When the baffle 52 is fully closed, the bait box 4 returns to its initial position, and the sow is now fully inside the outer shell 1. With the baffle 52 closed, the sow is completely confined within the outer shell 1. Therefore, by using a synchronization mechanism, the opening and closing of the baffle 52 and the movement of the bait box 4 are synchronized. As the sow gradually enters the outer shell 1, the baffle 52 gradually closes downwards, ensuring that the sow is successfully and easily lured into the outer shell 1 and confined, preventing her from escaping.

[0051] Example 4

[0052] Reference Figure 1-3As another preferred embodiment of the present invention, the difference from embodiment 3 is that two anti-collision mechanisms 6 are provided inside the outer shell 1, and the two anti-collision mechanisms 6 are respectively connected to both sides of the upper surface of the support platform 2. The anti-collision mechanism 6 includes several springs 61, anti-collision plates 62 and through openings 63. Several springs 61 are arranged in two rows and are respectively fixedly connected to the top of the inner wall of the outer shell 1 and the upper surface of the support platform 2. The anti-collision plates 62 are fixedly connected between the two rows of springs 61. The through openings 63 are opened through the anti-collision plates 62. The through openings 63 are used to allow the connecting frame 731 to pass through and move up and down.

[0053] When the sow is fully lured into the outer shell 1, she stands on the support platform 2. The sow's sides are blocked by several springs 61 and anti-collision plates 62. When a sudden situation occurs and the sow is frightened and rushes back and forth, the springs 61 and anti-collision plates 62 can play a role in preventing the sow from rushing back and forth and causing injury to herself. They can also prevent the sow from damaging the parts in the equipment.

[0054] Example 5

[0055] Reference Figure 3-14 As another preferred embodiment of the present invention, the difference from embodiment 4 is that a body lifting mechanism 7 is provided on both sides of the upper surface of the support platform 2, and the two body lifting mechanisms 7 are arranged opposite to each other. The body lifting mechanism 7 includes a one-way pushing mechanism 71, a lifting mechanism 72 and a support component 73. The one-way pushing mechanism 71 is located on one side of the second gear 55, the lifting mechanism 72 is located on the side of the one-way pushing mechanism 71 away from the baffle 52, and the support component 73 is connected to one side of the lifting mechanism 72 and is located on the upper surface of the support platform 2.

[0056] The unidirectional propulsion mechanism 71 includes a second rack 711, a first spring rod 712, a ring gear 713, an inner ring ratchet 714, a limiting tooth 715, and a second motor 716. One end of the second rack 711 is slidably mounted on the inner side wall of the outer casing 1 via the first spring rod 712. The second rack 711 is horizontally mounted and can perform horizontal linear motion under the action of the first spring rod 712.

[0057] The ring gear 713 is rotatably connected to the housing 1, and the second spur rack 711 meshes with the upper end of the ring gear 713. The inner ring ratchet 714 is fixedly connected to one side of the second gear 55, and the ring gear 713 is located on one side of the inner ring ratchet 714. The limiting tooth 715 is rotatably connected to one side of the ring gear 713, and the limiting tooth 715 is locked in the inner ring ratchet 714. The limiting tooth 715 is rotatably connected by a torsion spring. The second motor 716 is fixedly connected to the other side of the ring gear 713, and one end of the output shaft of the second motor 716 is fixedly connected to the limiting tooth 715. The second motor 716 is a micro motor.

[0058] The lifting mechanism 72 includes a connecting column 721, a second spring rod 722, a third rack 723, and a toothed roller 724. The connecting column 721 is slidably mounted on the inner wall of the outer casing 1 via the second spring rod 722. The third rack 723 is fixedly connected to one side of the connecting column 721. The connecting column 721 and the third rack 723 are vertically arranged, and under the action of the second spring rod 722, the connecting column 721 and the third rack 723 can perform vertical linear movement.

[0059] The toothed roller 724 is rotatably connected to the inner wall of the outer casing 1, and the third straight toothed rack 723 meshes with the toothed roller 724. The support assembly 73 is fixedly connected to one side of the connecting column 721. The support assembly 73 includes a connecting frame 731 and several support bars 732. The connecting frame 731 is fixedly connected to one side of the connecting column 721 and slides through the opening 63. Several support bars 732 are fixedly connected to the connecting frame 731 at equal intervals. Several support bars 732 are all located on the upper surface of the support platform 2. Several support bars 732 are all arc-shaped structures. Moreover, the several support bars 732 in two rows are arranged opposite to each other, which makes it more convenient and suitable for supporting and lifting the sow.

[0060] As the baffle 52 gradually closes downwards, the feeding box 4 moves back towards its initial position simultaneously, and the sow also gradually enters the outer shell 1. During this process, the first gear 54 rotates in the opposite direction, which in turn drives the second gear 55 to rotate in the opposite direction. The second gear 55 then drives the inner annular ratchet 714 to rotate. Since the rotation direction of the inner annular ratchet 714 at this time limits the locking teeth 715, the inner annular ratchet 714 drives the locking teeth 715 to perform circular motion. The circular motion of the locking teeth... The tooth 715 will drive the ring gear 713 to rotate, and the ring gear 713 will drive the second spur rack 711 to move horizontally in a straight line. When the second spur rack 711 moves to the toothed roller 724 and begins to mesh with it, it will drive the toothed roller 724 to rotate. The toothed roller 724 will drive the third spur rack 723 to move upward. The third spur rack 723 will drive the connecting column 721 to move upward. The connecting column 721 will drive the connecting frame 731 and the support bar 732 to move upward. Then, the several upward-moving support bars 732 on both sides will support and lift the sow. (During the forward rotation of the first gear 54, the baffle 52 moves upward and opens; the second gear 55 is also rotating forward, and the belt conveyor 3 carries the feeding box 4 towards the entrance of the outer shell 1; the inner annular ratchet 714 is also rotating forward, but the rotation direction of the inner annular ratchet 714 will not lock the limiting tooth 715, so the position of the limiting tooth 715 is fixed, the annular gear 713 will not rotate, the second spur rack 711 will also stop, and the two support components 73 will remain stationary on the support platform 2; in addition, there is a certain distance between the end of the second spur rack 711 and the toothed roller 724. This design is to ensure that the sow is lifted only when it has completely moved to the top of several support bars 732). Therefore, by setting up the body lifting mechanism 7, when the sow is fully inside the outer shell 1, the sow can be easily lifted up, thereby facilitating the sow's body position. On the one hand, lifting the sow can prevent the sow from struggling or colliding violently, making the mating process between the boar and the sow easier. On the other hand, since the sow is smaller than the boar, lifting the sow's body position allows the sow's reproductive organs to better connect with the boar's reproductive organs, thus making the mating process between the boar and the sow more convenient.

[0061] Working principle:

[0062] First, during the breeding process, the sow needs to be released from the pen and led to the equipment. Then, by running the conveyor belt 3, the feed box 4 is moved to the entrance of the outer shell 1. The sow next to the equipment will smell the feed in the feed box 4 and be attracted to walk into the outer shell 1. At this time, by running the conveyor belt 3 again, the feed box 4 is moved back to the initial position. In this process, the sow will be completely inside the outer shell 1 and follow the feed box 4 to the support platform 2. Finally, the sow will eat the feed safely inside the outer shell 1.

[0063] By activating the first motor 51, the first motor 51 drives the first gear 54 to rotate. The first gear 54 then drives the first spur rack 53 to move upward, which in turn drives the baffle 52 to move upward. When the baffle 52 is fully open, the belt conveyor 3 is adjusted to move the bait box 4 to the baffle 52, thus enticing the sow into the outer shell 1. Then, by adjusting the belt conveyor 3, the bait box 4 is moved back to its initial position, and the sow follows the bait box 4 into the outer shell 1. When the sow is fully inside the outer shell 1, the first motor 51 is reversed. The first motor 51 drives the first gear 54 to rotate in the opposite direction. The first gear 54 then drives the first spur rack 53 to move downwards. The first spur rack 53 then drives the baffle 52 downwards until the baffle 52 is completely closed. At this point, the sow is completely confined inside the outer shell 1 and cannot escape. During the process of opening the baffle 52 upwards by activating the first motor 51, the first motor 51 drives the first gear 54 to rotate. 4 will also drive the second gear 55 to rotate, the second gear 55 will drive the third gear 56 to rotate, the third gear 56 will drive the fourth gear 57 to rotate, and the fourth gear 57 will drive one of the pulleys in the belt conveyor 3 to rotate. This allows the belt conveyor 3 to move the bait box 4 to the entrance of the outer shell 1. During this process, as the baffle 52 gradually opens upwards, the bait box 4 will simultaneously move towards the entrance of the outer shell 1. When the baffle 52 is fully open, the bait box 4 will have just moved to the entrance of the outer shell 1. At the mouth, the sow can be lured. When the sow follows the bait box 4 into the outer shell 1, the first motor 51 is simultaneously reversed. Conversely, as the baffle 52 gradually closes downwards, the bait box 4 will move back towards the initial position. When the baffle 52 is completely closed, the bait box 4 will also return to the initial position. At this time, the sow has completely entered the outer shell 1, and the baffle 52 is in the closed state. Thus, the sow will be completely confined inside the outer shell 1.

[0064] Secondly, as the baffle 52 gradually closes downwards, the feeding box 4 simultaneously moves back towards its initial position, and the sow also gradually enters the outer shell 1. During this process, the first gear 54 rotates in the opposite direction, which in turn drives the second gear 55 to rotate in the opposite direction. The second gear 55 then drives the inner annular ratchet 714 to rotate. Since the rotation direction of the inner annular ratchet 714 at this time limits the locking teeth 715, the inner annular ratchet 714 will drive the locking teeth 715 to perform circular motion. Therefore, the locking teeth 715 will move in a circular motion. The positioning tooth 715 will drive the ring gear 713 to rotate, and the ring gear 713 will drive the second spur rack 711 to move horizontally in a straight line. When the second spur rack 711 moves to the toothed roller 724 and begins to mesh with it, it will drive the toothed roller 724 to rotate. The toothed roller 724 will drive the third spur rack 723 to move upward. The third spur rack 723 will drive the connecting column 721 to move upward. The connecting column 721 will drive the connecting frame 731 and the support bar 732 to move upward. Then, the several upward-moving support bars 732 on both sides will support and lift the sow.

[0065] Finally, the boar is released from the pen and led to the equipment. At this point, the staff needs to manually rotate and push the movable plate 582 upwards. Since the breeding pigs are in estrus and mating season, the boar will go into estrus when it sees the sow inside the shell 1 and will actively enter the shell 1 to mate with the sow.

[0066] Therefore, based on the above, firstly, by setting up the induction mechanism, the sow can be easily lured into the outer shell 1, thus pre-restricting the sow within it. Furthermore, during the process of restraining the sow, there is no need for staff to painstakingly push her into the mating chamber; the sow will voluntarily follow the bait box 4 into the outer shell 1, facilitating the mating process between the boar and the sow. Moreover, because the sow is restrained by the outer shell 1, it is difficult for her to break free or resist, making the mating process more convenient and stable. Secondly, by setting up the anti-escape mechanism 5, when the sow is completely lured into the outer shell 1 by the bait box 4... Upon entering the outer shell 1, the baffle 52 closes the entrance, effectively confining the sow completely within it. This prevents the sow from escaping in case of a sudden fright, thus facilitating the subsequent mating process between the boar and the sow. Furthermore, the one-way limiting mechanism 58, with the movable plate 582 hinged to the inside of the outer shell 1 and several limiting rods 583, ensures the sow can only enter from the outside and cannot escape from the inside. This facilitates the boar's entry into the outer shell 1 while preventing the sow from escaping. Next, through the synchronization mechanism, the opening and closing of the baffle 52 and the movement of the feeding box 4 can be synchronized simultaneously. This ensures that as the sow gradually enters the outer shell 1, the baffle 52 gradually closes downwards, guaranteeing that the sow can be successfully and easily lured into the outer shell 1 and confined, preventing her from escaping. Furthermore, the anti-collision mechanism 6, with the action of several springs 61 and anti-collision plates 62, can block the sow's sides. In the event of a sudden incident that frightens the sow and causes her to rush back and forth, the springs 61 and anti-collision plates 62 provide anti-collision and cushioning effects, preventing her from escaping. This design prevents the sow from injuring herself by bumping into things and also prevents her from damaging the components of the equipment. Finally, the body-lifting mechanism 7 allows the sow to be easily lifted up once she is fully inside the outer shell 1. This elevates the sow's position, preventing excessive struggling or bumping and facilitating mating between the boar and sow. Furthermore, since the sow is smaller than the boar, elevating her position allows for better contact between the sow's and boar's reproductive organs, further facilitating mating.
