Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for animal husbandry, specifically a crossbreeding aid for meat sheep. Background Technology

[0002] Hybridization technology in sheep farming is an important way to improve the production performance of sheep and optimize breed resources. Its core goal is to cultivate hybrid offspring with fast growth, high meat production performance, strong adaptability, and significant economic benefits through genetic complementarity between different breeds. At present, in order to overcome the high risk of inbreeding in natural conception, artificial insemination is often used in the breeding process. Artificial insemination involves collecting ram semen using the artificial vagina method, diluting it (containing yolk-sodium citrate preservative), packaging it, and freezing it. Then, deep insemination is performed by cervical / laparoscopic insemination during the estrus period of the ewe. Currently, the artificial insemination assisted breeding racks used usually involve workers driving the sheep onto the breeding rack and then fixing the sheep's body for insemination. However, this method is inefficient. The sheep often have low cooperation due to factors such as fright, and it is difficult for them to reach the designated position in one go, easily resulting in chaotic running and bumping. Therefore, it is necessary to make certain improvements to the current assisted breeding racks to meet the needs. Utility Model Content

[0003] To address the above technical problems, this utility model provides a crossbreeding aid for meat sheep.

[0004] To solve the above-mentioned technical problems, the present invention provides a crossbreeding auxiliary insemination rack for meat sheep, comprising a base and two limiting frames. The base has three grooves. Sliding rods are fixedly connected to the grooves on both sides via supports. A bidirectional threaded rod is rotatably connected to the groove in the middle via a support. Three support legs are fixedly connected to the lower end of each limiting frame. Two limiting frames are respectively installed at both ends of the grooves. The support legs on both sides are slidably connected to the sliding rods, and the support leg in the middle is threadedly connected to the bidirectional threaded rod. A motor is also fixedly connected to the base, and the motor is connected to the bidirectional threaded rod via a bevel gear transmission. A support frame is fixedly connected to the front end of the base, and a feed trough is fixedly connected to the support frame. Limiting rods are fixedly connected to both sides of the rear end of the base, and tail-end limiting straps are detachably connected to the limiting rods. Fixing ropes are also connected to the support legs on both sides of the limiting frame.

[0005] Furthermore, a front-end limiting band is fixedly connected between the limiting frame and the support frame.

[0006] Furthermore, the base is also hinged to a ramp at its tail end.

[0007] Furthermore, the motor is wrapped with sound-insulating cotton.

[0008] Furthermore, each of the three grooves is covered with a cover plate at its center.

[0009] This utility model has the following advantages compared with the prior art:

[0010] This invention uses a feed trough to guide sheep into the device. A motor drives a bidirectional threaded rod to rotate, which brings the two limiting frames closer together to clamp the sheep's body. Fixed ropes can be used to fix the sheep's four legs separately, preventing the sheep from kicking around during the vaccination process and greatly improving vaccination efficiency.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figures 1 to 3 The diagram shows a crossbreeding aid for meat sheep, comprising a base 1, two limiting frames 4, and three grooves within the base 1. Slide rods 2 are fixedly connected to the two side grooves via supports 11, with the supports 11 mounted at both ends of the slide rods. A bidirectional threaded rod 3 is rotatably connected to the middle groove via the supports 11 and bearings. The bidirectional threaded rod 3 has threads in opposite directions on both sides. Three support legs are fixedly connected to the lower end of the limiting frames 4, with two limiting frames 4 respectively mounted at both ends of the grooves. The two side support legs are slidably connected to the slide rods 2, and the middle support leg is threadedly connected to the bidirectional threaded rod 3. The base 1 also contains... A motor 13 is fixedly connected, and the motor 13 is connected to the bidirectional threaded rod 3 via a bevel gear 12. A support frame 5 is fixedly connected to the front end of the base 1, and a feed trough 6 is fixedly connected to the support frame 5. Limiting rods 8 are fixedly connected to both sides of the rear end of the base 1. A tail-end limiting strap 9 is detachably connected to the limiting rod 8. One end of the tail-end limiting strap 9 is fixedly connected to the limiting rod 8 on one side, and the other end of the tail-end limiting strap 9 is detachably connected to the limiting rod 8 via a hook. This allows the tail end to be closed after the sheep enters the device, preventing the sheep from running out. Fixing ropes 14 are also connected to the support legs on both sides of the limiting frame 4 to secure the sheep's four legs. For easy movement, casters can also be installed at the bottom of the base 1.

[0017] It should be noted that in this embodiment, motor 13 is a reversible motor.

[0018] To prevent the sheep from running out of the gap at the front, a front limiting band 7 is fixedly connected between the limiting frame 4 and the support frame 5. The length of the limiting band 7 is greater than the maximum distance between the limiting frame 4 and the support frame 5.

[0019] To facilitate the entry of sheep into the device, a ramp 10 is hinged to the end of the base 1. After use, the ramp can be folded up for easy transfer and to save storage space.

[0020] To prevent the noise from the motor 13 during operation from causing excessive fright to the sheep, the motor 13 is wrapped with sound-absorbing cotton.

[0021] To prevent the sheep's hooves from sinking into the grooves, the center of each of the three grooves is covered with a cover plate.

[0022] The working process of this embodiment is as follows:

[0023] Before inoculation, sheep in estrus should be kept in separate pens. It is best not to feed them for 6 hours before inoculation. When inoculation is needed, lower the ramp 10 at the tail end of the device, remove the hook at one end of the tail end limit strap 9, align the tail end with the pen door, and add hay or feed to the feed trough 6. Then open the pen door. After the sheep enters the device and begins to eat the hay, the operator hangs up the tail end limit strap 9 to prevent the sheep from running back into the pen from the tail end. Then start the motor 13, which drives the bidirectional threaded rod 3 to rotate, thereby bringing the limit frames 4 on both sides closer together. After the limit frames 4 hold the sheep stably, turn off the motor 13. The operator uses the fixing rope 14 to fix the sheep's four legs to the support legs of the limit frames 4. After fixing, the inoculation operation can begin. After the inoculation and insemination are completed, open the end of the tail limit belt 9 with the hook, open the fixing rope 14, control the motor 13 to reverse, so that the limit frame 4 separates and the sheep returns to the sheep pen along the original route. Close the pen door, retract the ramp 10, and clean the residual feed in the feed trough 6.
