[0002] Piglet castration technology aims to remove the ovaries or testicles of piglets through surgery, making them lose their reproductive ability. This technology not only helps to increase the growth rate of piglets, but also significantly improves feed utilization. However, the quality of implementation of this technology is deeply affected by the proficiency of the operator. During the operation, secondary infection may be caused by improper operation, which will not only hinder the normal growth of piglets, but also may cause serious economic losses.

[0003] At present, during piglet castration surgery, the piglet is fixed on a bracket and held down manually, and then the castrator performs the castration surgery on the piglet. However, the piglet is easily shaken during the operation, resulting in a poor castration effect. At the same time, the operator's surgical angle will also affect the castration efficiency.

[0044] A worm 113 is rotatably connected to the inner wall of the outer side of the cross bottom plate 110, a motor 114 is fixedly installed on the inner wall of the outer side of the cross bottom plate 110, and the output end of the motor 114 is fixedly connected to the end wall of the worm 113, a worm wheel 115 is rotatably connected to the inner wall of the middle part of the cross bottom plate 110, and the worm wheel 115 is meshed with the worm 113, a turntable 116 is fixedly installed on the top of the worm wheel 115, the tops of both ends of the cross bottom plate 110 are rotatably connected to triangular plates 118, and both ends of the top of the turntable 116 are rotatably connected to connecting rods 117, and the end walls of the two groups of connecting rods 117 are rotatably connected to the end corners of the two groups of triangular plates 118 respectively, and the other two groups of end corners of the triangular plates 118 are rotatably connected to spherical push rods 116. 19. The other end of the spherical push rod 119 is engaged with the corresponding spherical groove seat 128. In the present invention, the driving motor 114 drives the worm 113 to engage with the worm wheel 115, thereby driving the turntable 116 to rotate, so that the turntable 116 drives the connecting rod 117 to push the triangular plate 118 outward, thereby pulling the two groups of spherical push rods 119. At this time, the spherical push rod 119 can drive the spherical groove seat 128 to move, so that the push angle 123 rotates, and the inner gear ring 122 engages with the outer gear ring 125, thereby driving the rotating column 124 to rotate, so that the three groups of tooth plates 126 rotate inward, forcing the three groups of air bags 127 to fix the piglet's limbs.

[0045] In this embodiment, if Figures 10 to 15As shown, the same supporting arch plate 130 is fixedly installed at the four corners of the top of the cross bottom plate 110. The supporting arch plate 130 has an arc setting, which can fit the abdomen of the piglet and is convenient for fixing the piglet. The four corners of the side wall of the supporting arch plate 130 are fixedly installed with limiting cylinders 131. The bottoms of the four groups of limiting cylinders 131 are respectively fixedly connected to the tops of the four groups of C-shaped circles 112. The limiting cylinders 131 can play a role in guiding the limbs of the piglet. The two sides of the middle part of the supporting arch plate 130 are rotatably connected with arc splints 140. The tops of both sides of the middle part of 110 are rotatably connected with cylinders 141, and the output ends of the cylinders 141 are rotatably connected with the outer walls of the corresponding arc-shaped splints 140. The arc-shaped splints 140 can fix the piglets. When the operator places the piglets on the supporting arch plate 130 and puts the limbs deep into the foot binding tube 111, the cylinders 141 are driven to push the arc-shaped splints 140 inward, thereby fixing the piglets. When the piglets are placed and moved to the bottom of the disc 210, they are detached from the supporting arch plate 130.

[0046] As an implementation method in this embodiment, Figures 6 to 9 As shown, a plurality of groups of strip grooves 214 are provided on the inner wall of the rotating drum 213, and a plurality of groups of clamping strips 221 are fixedly installed on the outer wall of the pig placing drum 220. The clamping strips 221 on the pig placing drum 220 located inside the rotating drum 213 are engaged with the corresponding strip grooves 214, and the pig placing drum 220 is slidably connected with the corresponding inner wall of the rotating drum 213. A displacement device 222 is fixedly installed on the inner wall at the top of the pig placing drum 220, and the output end of the displacement device 222 is fixedly connected to the bottom of the cross bottom plate 110. Slide rails 223 are fixedly installed on the outer walls on both sides of the pig placing drum 220, and the two side walls of the cross bottom plate 110 are slidably connected with the corresponding slide rails 223 respectively. In the present invention, while the disc 210 rotates, the displacement device 222 is driven to transport the piglets from the inside to the outside, so that the piglets' buttocks can be exposed, thereby facilitating castration by the operator.

[0047] In this embodiment, if Figures 3 to 8As shown, the inner wall of the bracket 200 is rotatably connected with a gear 240, and a motor 241 is fixedly installed on the inner wall of the bracket 200, and the output shaft of the motor 241 is fixedly connected to the gear 240, and the outer wall of the disc 210 located on the outside is fixedly installed with an outer gear ring 212, and the outer gear ring 212 is meshed with the gear 240. The motor 241 is started to drive the gear 240 to mesh with the outer gear ring 212, thereby driving the disc 210 to rotate, and the same positioning rod 230 is fixedly installed on the inner walls on both sides of the middle part of the bracket 200, and the positioning rod 230 passes through the two groups of discs 210, and a positioning gear 231 is fixedly installed in the middle of the positioning rod 230, and an outer gear ring 3 215 is fixedly installed on the outer wall of the middle part of the rotating drum 213, and the positioning gear 231 is meshed with the five groups of outer gear rings 3 215. When the five groups of rotating drums 213 installed on the disc 210 move with the disc 210, the rotating drum 213 is rotated at this time. The outer gear ring three 215 on 213 can mesh with the positioning gear 231, thereby driving the rotating drum 213 to rotate in the disc 210, and the end wall of the positioning rod 230 is rotatably connected with a conductive slip ring 232, which can power the displacement device 222, the motor 1 114 and the motor 241. In the present invention, the driving motor 241 allows the disc 210 to drive the rotating drum 213 to move, so that the outer gear ring three 215 outside the rotating drum 213 is meshed with the positioning gear 231, thereby driving the rotating drum 213 to rotate in the disc 210, and the pig placing tube 220 can rotate with the rotating drum 213 under the limiting action of the clamping strip 221. At this time, the piglet fixed in the pig placing tube 220 will also rotate. When the pig placing tube 220 with the piglet installed moves to the bottom of the disc 210, the piglet just flips 180°, thereby facilitating the castration operation.

[0048] The working principle of the technical solution provided by the present invention is as follows: the castration device requires two personnel to operate, one of whom is responsible for placing pigs on and off the upper part of the device, and the other is responsible for castration at the lower part. The upper part of the staff places the piglets on the supporting arch plate 130 (see the attached manual). Figure 5 , 10 , 11), and extend its limbs through the limit tube 131 into the foot binding tube 111, and drive the motor 114 to drive the worm 113 to mesh with the worm wheel 115, thereby driving the turntable 116 to rotate, so that the turntable 116 drives the connecting rod 117 to push the triangular plate 118 outward, thereby pulling the two sets of spherical push rods 119. At this time, the spherical push rods 119 can drive the spherical slot seat 128 to move, so that the push angle 123 rotates, so that the inner gear ring 122 and the outer gear ring 125 mesh, thereby driving the rotating column 124 to rotate, so that the three sets of tooth plates 126 rotate inward, forcing the three sets of air bags 127 to fix the piglet's limbs;

[0049] After the piglets are fed, the motor 241 is started to drive the gear 240 to mesh with the outer gear ring 212, thereby driving the disc 210 to rotate, and the five groups of rotating drums 213 installed on the disc 210 will also move with the disc 210. At this time, the outer gear ring 3 215 on the rotating drum 213 can mesh with the positioning gear 231, thereby driving the rotating drum 213 to rotate in the disc 210. Under the limiting effect of the clamping strip 221, the pig placing barrel 220 can rotate with the rotating drum 213. At this time, the piglets fixed in the pig placing barrel 220 will also rotate. When the pig placing barrel 220 with the piglets installed moves to the bottom of the disc 210, the piglets just flip 180°, that is, the piglets' limbs are facing upwards (refer to the attached manual Figure 5 , 6 ), while the disc 210 rotates, the displacement device 222 is driven to transport the piglets from the inside to the outside. Thereafter, the staff located on the lower outside can castrate the piglets. After the castration is completed, the disc 210 is continued to be driven to rotate, and the displacement device 222 is driven to transport the castrated piglets back to the top of the disc 210, and the staff on the inside move the piglets down, thereby completing a complete set of piglet castration process.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention.
