Abstract
Description
Technical Field
[0001] This application relates to dairy cow breeding technology, and more particularly to a dairy cow breeding aid device. Background Technology
[0002] In large-scale dairy farming, when dairy cows are artificially inseminated, insemination aids are usually used to restrict the cows' range of movement and assist workers in completing the insemination process.
[0003] Currently, existing insemination aids used for artificial insemination in dairy cows typically only restrict the cow's body and head, but cannot restrict the tail. The tail is prone to swinging, affecting the insemination process. To avoid the tail interfering with insemination, a worker usually needs to hold the tail and pull it to one side to expose the vulva before artificial insemination. Moreover, the worker needs to continuously hold the tail to prevent it from swinging during the artificial insemination process, which not only increases the worker's workload but also results in poor stability when manually holding the tail. If the worker's grip is insufficient, the cow may resist the tail swinging and it may break free from the worker's hand, thus affecting the artificial insemination operation. Utility Model Content
[0004] This application provides a dairy cow insemination assistance device to solve the problems of high labor intensity and easy escape of the cow's tail from the worker's hand during artificial insemination of dairy cows, which affects the artificial insemination operation.

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0026] like Figures 1-5 As shown:
[0027] An embodiment of this application provides a dairy cow mating assistance device, which includes two symmetrically distributed side frames 1, and a front frame 2 that can clamp the cow's neck is fixed between one end of the two side frames 1.
[0028] One of the side frames 1 has a ring-shaped clamping ring 3 at the top of its other end. The ring wall of the clamping ring 3 is hollow, and the inner ring wall of the clamping ring 3 is made of elastic rubber.
[0029] The clamping ring 3 is connected to a pressure regulating device 4 that can adjust the air pressure inside the ring.
[0030] In this embodiment, the front frame 2 is fixedly connected to the front end of the side frame 1, and the clamping ring 3 and the air pressure regulating device 4 are both located at the upper rear end of the side frame 1 on the left side. Both the front frame 2 and the side frame 1 are fixed to the ground.
[0031] During use, the cow to be inseminated is led between the two side frames 1 and its neck is clamped by the front frame 2 to restrict the cow's head and body. Then, the worker manually pulls the cow's tail to the left and passes it through the clamping ring 3. The worker then holds the cow's tail with one hand to prevent it from swinging out of the clamping ring 3, while the worker operates the air pressure regulating device 4 with the other hand to increase the air pressure inside the clamping ring 3. After the air pressure inside the ring increases, the inner ring wall of the clamping ring 3 expands towards the center of the clamping ring 3 under the action of air pressure and clamps the cow's tail, thus restricting the tail. At this point, artificial insemination can be performed.
[0032] The dairy cow insemination aid device provided in this embodiment, by setting two side frames 1 and a front frame 2 fixed between one end of the two side frames 1 to clamp the cow's neck, can restrict the cow's head and body. A clamping ring 3 with a hollow structure and an inner wall made of elastic rubber is set on the side frames 1, and an air pressure regulating device 4 is connected to the ring wall of the clamping ring 3 to adjust the internal air pressure. When the air pressure regulating device 4 increases the internal air pressure of the clamping ring 3, the inner ring wall of the clamping ring 3 can expand and clamp the cow's tail. During artificial insemination, it is not necessary to manually pull the cow's tail, reducing the labor intensity of the workers. Moreover, the expansion of the inner ring wall clamping the cow's tail provides high stability; even if the cow resists shaking its tail, the tail will not break free of the clamping ring 3. Furthermore, the method of clamping the cow's tail by expanding the inner ring wall can clamp tails of different thicknesses, making it widely applicable.
[0033] In some embodiments of this application, the inner ring wall of the clamping ring 3 includes a plurality of annular members 301 distributed along the axial direction of the clamping ring 3, and an annular arc-shaped protrusion 302 is connected between two adjacent annular members 301.
[0034] The thickness of the protruding structure 302 is less than the thickness of the annular part 301.
[0035] Furthermore, the annular component 301 and the protruding structure 302 are integrally formed.
[0036] In this embodiment, since the thickness of the protruding structure 302 is less than the thickness of the annular member 301, the increased air pressure inside the ring wall of the clamping member causes the multiple protruding structures 302 to expand towards the center of the clamping ring 3 and clamp the cow tail. Furthermore, the annular arc-shaped protruding structure 302 facilitates the expansion of the inner ring wall of the clamping ring 3.
[0037] In some embodiments of this application, the clamping ring 3 is mounted on the top of the side frame 1 via the universal ball joint structure 5.
[0038] Furthermore, the universal ball joint structure 5 includes a mounting base, the upper end of which is inlaid with a movable ball joint. The mounting base is fixed to the upper end of the side frame 1 located on the left side, and the ball joint is fixedly connected to the lower end of the clamping ring 3.
[0039] In this embodiment, after the clamping ring 3 is installed on the universal ball joint structure 5, the clamping ring 3 can move with multiple degrees of freedom. Therefore, after the clamping ring 3 clamps the cow's tail, when the cow resists swinging its tail, the clamping ring 3 can move with the cow's tail within a certain range, thereby improving the comfort of the cow's tail.
[0040] In some embodiments of this application, the air pressure regulating device 4 includes a cylinder 401, inside which is a fitted piston 402. A movable piston presses against the inner wall of the cylinder 401. The piston 402 is rotatably connected to a screw 403 extending out of the cylinder 401, and the upper end of the screw 403 is threadedly connected to the cylinder 401. Specifically, an internally threaded sleeve 404 is fixed to the upper end of the cylinder 401, and the screw 403 passes through and engages with the internally threaded sleeve 404. A knob 405 is fixed to the upper end of the screw 403.
[0041] The lower inner part of the cylinder 401 is connected to the inner wall of the clamping ring 3 via a flexible hose 406 to ensure that the clamping ring 3 can move smoothly with the cow's tail. Specifically, one end of the flexible hose 406 is connected to the inside of the cylinder 401 and is sealed and fixedly connected to the cylinder 401, while the other end of the flexible hose 406 is connected to the inner wall of the clamping ring 3 and is sealed and fixedly connected to the clamping ring 3.
[0042] In use, the operator manually rotates knob 405, which drives screw 403 to rotate, and screw 403 drives piston 402 to move. When piston 402 moves down, it forces the gas inside cylinder 401 into the inner wall of clamping ring 3, increasing the gas pressure inside the ring wall and causing the inner ring wall of clamping ring 3 to expand. When piston 402 moves up, cylinder 401 draws in the gas inside the ring wall of clamping ring 3, decreasing the gas pressure inside the ring wall and causing the expanded inner ring wall to contract, releasing the inner ring wall from clamping the cow's tail.
[0043] In some embodiments of this application, the front frame 2 includes a hollow frame body 201. A rotatable shaft 202 is provided at the lower part of the frame body 201. The shaft 202 is rotatably connected to the frame body 201 via bearings. The shaft 202 has two symmetrically distributed external threaded structures 203 with opposite directions of rotation. Clamping rods 204 are threadedly connected to the external threaded structures 203, and the upper part of the clamping rods 204 is sleeved on the upper end of the frame body 201 and slidably connected to the frame body 201. Specifically, the upper part of the clamping rods 204 is sleeved on the upper end of the frame body 201 and slidably connected to the frame body 201.
[0044] When in use, the cow stands behind the two side plates, with its head extending out of the front frame 2, meaning the cow's neck is positioned between the two clamping plates. Then, the rotating shaft 202 is rotated, which simultaneously causes the two clamping rods 204 to move towards each other. The two clamping rods 204 clamp the cow's neck, thus restricting the cow's head.
[0045] In some embodiments of this application, handwheels 205 are fixed at both ends of the rotating shaft 202 to facilitate the rotation of the rotating shaft 202 by the operator.
[0046] In use, staff only need to manually rotate one of the handwheels 205 to rotate the shaft 202.
[0047] In some embodiments of this application, the other end of each of the two side frames 1 is provided with a stop bar 6 for restricting the cow's hind legs to prevent the cow's hind legs from kicking people.
[0048] The stop lever 6 is fixed with a drive shaft 7. The two ends of the drive shaft 7 are rotatably connected to the side frame 1 and the front frame 2 respectively through bearings, and the drive shaft 7 is connected to the upper rotating shaft 202 through a worm gear transmission mechanism 8.
[0049] Furthermore, the stop rod 6 is located at the rear end of the side frame 1, and one end of the stop rod 6 is sleeved and fixed on the transmission shaft 7. The worm gear transmission mechanism 8 includes a worm wheel and a worm. The worm wheel is fixed on the transmission shaft 7, and the worm is sleeved and fixed on the rotating shaft 202. The worm wheel and the worm mesh.
[0050] In this embodiment, the initial state is that the distance between the two clamping rods 204 is greater than the cow's head, and the stop bar 6 is vertically distributed. When the cow's head extends out of the front frame 2, the operator manually rotates one of the handwheels 205. The handwheel 205 drives the rotating shaft 202 to rotate, and the rotating shaft 202 drives the two clamping rods 204 to move towards each other to clamp the cow's neck. At the same time, the rotating shaft 202 drives the transmission shaft 7 to rotate through the worm gear transmission mechanism 8, and the transmission shaft 7 drives the stop bar 6 to rotate. When the two clamping rods 204 clamp the cow's neck, the two stop bars 6 rotate to a horizontal distribution and are located behind the cow's hind legs, restricting the cow's hind legs and preventing the cow from kicking. In this way, only the handwheel 205 needs to be rotated to achieve synchronous restriction of the clamping rods 204 and the stop bar 6 on the cow, thus achieving the effect of convenient operation.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
