It is an extremely important link in the material exchange between humans and nature. Animal husbandry is an important part of agriculture and is listed as one of the two pillars of agricultural production along with planting. Animal husbandry is a comprehensive discipline that studies livestock breeding, reproduction, feeding, management, disease prevention and epidemic prevention, as well as grassland construction, livestock product processing and livestock management and management.

Telescopic components 503 are fixedly mounted on the inner walls of both sides of the placement grooves 502, and a clamping block 504 is fixedly mounted on the side of the telescopic component 503 away from the inner wall of the placement groove 502. The clamping block 504 can clamp and fix the hind hoof of the livestock under the elastic force of the telescopic component 503.

[0050] In order to keep the clamping plate 205 stable during the height adjustment process, Figure 4 As shown, the neck fixing mechanism 2 includes a movable groove 206, and two movable grooves 206 are provided. The inner walls of the two movable grooves 206 are movably connected to the outer walls of the two sliders 203 respectively. The movable groove 206 can limit the movement of the slider 203, so that the clamping plate 205 remains stable during the height adjustment process, so that the clamping plate 205 can stably fix the necks of different livestock.

[0051] In order to enable the corner fixing mechanism 3 to fix the corners at different angles, Figure 5 As shown, the horn fixing mechanism 3 includes a rotating seat 303, and two rotating seats 303 are provided. The two rotating seats 303 are respectively fixedly installed on the outer wall of one end of the two traction plates 302 away from the second electric push rod 301, and the inner sides of the two rotating seats 303 are respectively rotatably connected to the outer walls of two limiting rings 304, and the limiting rings 304 are rotatably installed on the outer sides of the rotating seats 303, and then the height of the limiting rings 304 can be adjusted by operating the second electric push rod 301, so that the two limiting rings 304 can fix horns with different inclination degrees.

[0053] In order to keep the clamping plate 412 stable during the height adjustment process, Figure 6As shown, the waist fixing mechanism 4 includes two second motors 409, and the two second motors 209 are respectively fixedly installed on the tops of the two fixing frames 406, and the two second motors 209 are respectively connected to the two second screw rods 408 through output shaft transmission. The waist fixing mechanism 4 includes two mounting grooves 407, and the two mounting grooves 407 are respectively opened on the inner walls of the two fixing frames 406, and the inner walls of the two mounting grooves 407 are respectively rotatably connected to the two second screw rods 408, and the inner walls of the two mounting grooves 407 are respectively movably connected to the outer walls of the two mounting seats 410. The operation of the second motor 409 causes the second screw rod 408 to rotate, and then the height of the clamping plate 412 can be adjusted. The mounting groove 407 can limit the movement of the mounting seat 410, so that the clamping plate 412 remains stable during the height adjustment process.

[0054] In order to keep the waist fixing mechanism 4 stable during the movement, Figure 3 and Figure 6 As shown, the inner walls of the two limiting grooves 6 are rotatably connected to the two first screw rods 401 respectively, and the outer walls of the two first screw rods 401 are threadedly sleeved with movable seats 405.

The limiting grooves 6 can limit the movement of the movable seats 405, and then limit the movement of the fixed frames 406, so that they remain stable during the movement.

[0055] The specific implementation method is as follows: during animal husbandry work, when livestock are sick, veterinarians need to perform injections on the livestock according to the livestock's condition. When injecting livestock, they need to be fixed to prevent them from moving around during the injection process, and then the livestock are driven to the top of the fixed base 1, and then the first motor 402 is operated to make one of the first screw rods 401 rotate, and through the transmission action of the rotating sprocket 403 and the transmission chain 404, the other first screw rod 401 is rotated, and then the two fixed frames 406 can be moved on the outside of the first screw rod 401 through the movable seat 405, and then the distance between the fixed frame 406 and the mounting frame 201 can be adjusted, and then the hind hoof fixing mechanism 5 can be driven to move, and then when the livestock are When the neck of the livestock moves between the two mounting frames 201, the staff places the two hind hooves of the livestock into the two placement grooves 502, so that the hind hooves can squeeze the clamping block 504, thereby causing the telescopic assembly 503 to contract. After the hind hooves of the livestock are placed, the clamping block 504 can clamp and fix the hind hooves of the livestock under the elastic force of the telescopic assembly 503, and then the two second motors 409 work to make the two second screw rods 408 rotate, so that the two mounting seats 410 can move along the inner wall of the mounting groove 407 on their outside, so that the clamping plate 412 can be adjusted in height, and then the two third electric push rods 411 work to make the two clamping plates 412 fix the position of the livestock waist close to the hind limbs;

[0056] After the hind limbs of the livestock are fixed, the two hydraulic cylinders 202 work to make the two sliders 203 move along the inner wall of the movable groove 206, so that the height of the two clamping plates 205 can be adjusted, and the two first electric push rods 204 work to make the two clamping plates 205 fix the neck of the livestock. While the clamping plates 205 are adjusted, the two second electric push rods 301 work to make the two traction plates 302 move upward, so that the height of the limiting ring 304 can be adjusted. When the clamping plates 205 fix the neck of the livestock, the two limiting rings 304 can fix the horns of the livestock, so that the livestock can be moved. The head of the livestock (such as cattle and sheep) can be well fixed, thereby preventing the livestock's head from moving around during the injection process, which could cause injuries to the staff due to the horns. The livestock's hind limbs can be fixed by the waist fixing mechanism 4 and the hind hoof fixing mechanism 5, thereby preventing the livestock from kicking around with their hind limbs during the injection process, allowing the livestock to remain stable during the injection process, thereby ensuring the safety of the livestock during the injection process and the safety of the staff. This embodiment specifically solves the problem in the prior art that the livestock's horns cannot be fixed during the injection process, causing the horns to move around and easily causing injuries to the livestock and staff.

[0057] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
