Description

Technical Field

[0001] This invention relates to the field of animal husbandry technology, specifically to a restraining yoke for breeding superior cattle breeds. Background Technology

[0002] In large-scale livestock farming, especially in the breeding of improved cattle breeds, it is necessary to frequently perform artificial insemination, pregnancy checks, and disease prevention and treatment on cattle. In order to prevent cattle from struggling and injuring people and to ensure the accuracy of the operation, special restraint devices are needed to fix and limit the cattle.

[0003] Chinese utility model patent (CN2023229120491) discloses a cattle neck restraint device, which includes a frame with a front door and a rear door at each end. The front door has a neck protrusion opening and is equipped with a connecting rod assembly. The connecting rod assembly includes four push rods, which are hinged to each other by right-angle connecting rods. The bends of the right-angle connecting rods are hinged to the front door. Two pairs of restraint components are located near the neck protrusion opening on the front door. Each restraint component includes a sliding post, an arc-shaped restraint plate, a pressure plate, and a compression spring. One end of the sliding post is connected to the arc-shaped restraint plate, and the other end is connected to the pressure plate. The pressure plate abuts against the push rod, and the compression spring is located between the guide rail and the pressure plate. This device achieves rapid and automatic restraint of the cattle's neck through four sets of restraint components, which can reduce the stress response of cattle to a certain extent.

[0004] However, this cattle neck restraint device has the following shortcomings: the clamping center of the two pairs of restraint components is fixed, which cannot be adapted to cattle of different body sizes and growth stages. The clamping adaptability is poor, and it only restricts the cattle's neck, making the cattle's body prone to shaking and twisting. It is difficult to meet the stability requirements of high-precision operations such as artificial insemination and rectal pregnancy examination in the breeding of cattle. At the same time, the ease of operation is insufficient, and it cannot meet the high-efficiency operation requirements of large-scale breeding of cattle. Summary of the Invention

Detailed Implementation

[0032] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0033] Please see Figures 1 to 7 This invention discloses a restraint yoke for breeding improved breed cattle, including a frame 100, a neck fixing structure, and a body fixing structure 500. The neck fixing structure is used to clamp and fix the neck of the cattle to prevent the head from breaking free. The body fixing structure 500 is used to clamp and limit the sides of the cattle's torso to restrain the left and right swinging of the cattle's body.

[0034] like Figure 1 and Figure 2 As shown, the frame 100 is a cuboid frame structure. The two ends of the frame 100 are respectively provided with a front passage 101 and a rear passage 102 for cattle to pass through. The cattle neck fixing structure includes a horizontal clamping component 200 and a vertical clamping component 300. The horizontal clamping component 200 is used to clamp and limit the cattle neck from the left and right sides, and the vertical clamping component 300 is used to hold and fix the cattle neck from the top and bottom.

[0035] The horizontal clamping assembly 200 includes a double-leaf door 201, a guide rod 202, a linkage mechanism, and a lever clamp 203. The double-leaf door 201 consists of two independently arranged door panels, which are slidably disposed on both sides of the front passage 101 of the frame 100. When the double-leaf door 201 slides towards each other, it can close the front passage 101; when it slides away from each other, it can open the front passage 101. The guide rod 202 is fixedly connected to the upper frame wall of the front passage 101, and a vertical support plate 210 is fixedly disposed above the front passage 101. The linkage mechanism includes a lifting component, a first connecting rod 206, a lever 207, and an operating rod 208. The lifting component is vertically slidable. The first connecting rod 206 is placed on the front end face of the vertical support plate 210. There are two symmetrically arranged first connecting rods 206. One end of the two first connecting rods 206 is respectively hinged to the lower part of both sides of the lifting component. The other end of the first connecting rod 206 is respectively hinged to the sliding sleeve 209. The two sliding sleeves 209 are respectively slidably sleeved on the guide rod 202. The top of the double-leaf door 201 is respectively fixedly connected to the two sliding sleeves 209. The lever 207 is hinged to the upper part of the front end of the frame 100. One end of the lever 207 is hinged to the side of the lifting component, and the other end is hinged to the top of the operating rod 208. The operating rod 208 can be detachably snapped into the rod clamp 203 fixed on the outer wall of the frame 100.

[0036] like Figure 1 , Figure 2 as well as Figure 3 As shown, a lifting adjustment assembly 400 is provided on one of the doors of the double-leaf door 201. A vertical clamping assembly 300 is installed on the double-leaf door 201 through the lifting adjustment assembly 400, and the vertical clamping assembly 300 includes a fixed support 401, a linear drive 402, an intermediate connecting seat 403, a hinged support 404, a drive arm 405, and a clamping arm 406. The fixed support 401 and the hinged support 404 are positioned along the width direction of the double-leaf door 201. The drive arm 405 and the clamping arm are symmetrically arranged on the front side of the double-leaf door 201. The output end of the linear drive 402 passes through the fixed support 401 and is connected to the intermediate connecting seat 403. One end of each of the two drive arms 405 is hinged to the intermediate connecting seat 403, and the other end is hinged to the clamping arm 406. One end of the clamping arm 406 is hinged to the hinge support 404. The free ends of the two clamping arms 406 can rotate relative to each other around the hinge point to realize opening and closing.

[0037] like Figure 1 and Figure 5 As shown, the cow body fixing structure 500 includes a drive mechanism fixed to the top of the frame 100 and side panel windows 501 slidably assembled on both sides of the frame 100. The drive mechanism drives the side panel windows 501 to move towards or away from each other to clamp or release the cow body.

[0038] In this embodiment, the process of securing cattle in a restraint yoke for breeding improved breed cattle is as follows:

[0039] First, unlock and remove the operating lever 208 from the lever clamp 203. Drive the cattle into the frame 100 through the rear passage 102, positioning the cattle's neck between the split doors 201. Pull the operating lever 208 downwards, causing the lever 207 to rotate around its hinge point with the frame 100. This drives the lifting component to slide vertically upwards along the vertical support plate 210. The upward movement of the lifting component causes the two first connecting rods 206 to move synchronously, driving the two sliding sleeves 209 to slide towards each other along the guide rod 202. This, in turn, causes the split doors 201 to move towards each other, achieving lateral clamping and positioning of the cattle's neck. After clamping, re-clamp and fix the operating lever 208 to the lever clamp 203 to complete the lateral limit locking.

[0040] Next, the installation height of the lifting adjustment component 400 is adjusted according to the different neck heights of the cattle. During vertical clamping operations, the linear drive component 402 is activated. The output end of the linear drive component 402 extends and drives the intermediate connecting seat 403 to move horizontally. The intermediate connecting seat 403 drives the two symmetrically arranged drive arms 405 to move synchronously and drive the two clamping arms 406 to rotate relative to each other around the hinge fulcrum of the hinge support 404 to close, thereby realizing the vertical clamping and limiting of the cattle's neck and completing the vertical clamping and fixing of the cattle's neck.

[0041] Finally, during the cattle body fixation operation, the drive mechanism at the top of the frame 100 is activated. The drive mechanism drives the side panel windows 501 on both sides of the frame 100 to move synchronously towards each other along the frame 100. The side panel windows 501 on both sides move inward to clamp and fix the left and right sides of the cattle body, restraining the swaying and twisting of the cattle's torso.

[0042] In this embodiment, the process of removing the restraints from cattle used for breeding high-quality livestock is as follows:

[0043] First, the control drive mechanism reverses its rotation, causing the side panel windows 501 on both sides to move synchronously in opposite directions along the frame 100 and open outwards, thus releasing the clamping limit on the cow's body.

[0044] Next, the output end of the linear drive 402 retracts, causing the intermediate connecting seat 403 to move in the opposite direction. The drive arm 405, in conjunction with the two clamping arms 406, rotates and opens relative to each other around the hinge fulcrum of the hinge support 404, releasing the vertical clamping of the cow's neck.

[0045] Finally, when releasing the lateral clamp, remove the operating rod 208 from the rod clamp 203, push the operating rod 208 upward, the lever 207 rotates in the opposite direction around the hinge fulcrum and drives the lifting component to slide downward vertically. The downward movement of the lifting component drives the first connecting rod 206 to move in the opposite direction, so that the two sliding sleeves 209 slide in opposite directions along the guide rod 202, and the double-leaf door 201 moves in opposite directions synchronously, releasing the lateral clamp on the cow's neck.

[0046] This embodiment of the livestock breeding cattle restraint yoke features a dual-dimensional neck fixation structure with both lateral and vertical clamping, coupled with a height-adjustable lifting mechanism. This allows for flexible adaptation to cattle of varying neck heights, body sizes, and growth stages, solving the problems of fixed clamping centers and poor adaptability in existing technologies. Simultaneously, the dual-sided synchronous drive body fixation structure provides comprehensive three-dimensional restraint of the neck and torso, effectively controlling excessive movements such as swaying, twisting, and sitting back, thus improving the stability and accuracy of high-precision operations in artificial insemination and rectal pregnancy testing for breeding cattle. Furthermore, the lever linkage and rod transmission structure ensures simple and quick clamping and release operations, with uniform force distribution on both sides without bias.

[0047] like Figure 3 As shown, the lifting adjustment assembly 400 includes a slide rail 301, a slide plate 302, and a locking screw 303. The slide rail 301 is fixed on one side of the double-leaf door 201 along the height direction of the frame 100. The slide rail 301 has a T-shaped structure. The slide plate 302 has a lifting groove 304 that matches the T-shaped slide rail 301. The slide plate 302 forms a sliding fit with the slide rail 301 through the lifting groove 304, realizing the lifting movement of the slide plate 302 along the T-shaped slide rail 301. The locking screw 303 is threaded through the slide plate 302, and its inner end can press and lock against the surface of the slide rail 301. The fixed support 401 and the hinge support 404 are both fixed on the slide plate 302 and rise and fall synchronously with the slide plate 302. The lifting and locking positioning of the slide plate 302 can be quickly completed by turning the locking screw 303, making the installation height of the vertical clamping component 300 flexibly adjustable. It can accurately adapt to different body sizes and neck heights of good breed cattle, effectively broadening the application range of the restraint yoke and meeting the breeding restraint operation needs of good breed cattle at different growth stages.

[0048] like Figure 2 As shown, in this embodiment, the linkage mechanism also includes a compression spring 213. The lifting component includes a vertical rod 204 and a horizontal plate 205. The bottom end of the vertical rod 204 is connected to the center of the top end of the horizontal plate 205 to form a T-shaped structure. A pressure plate 211 is fixedly sleeved in the middle section of the vertical rod 204. A guide plate 212 located below the pressure plate 211 is fixedly sleeved on the front end face of the vertical support plate 210. The vertical rod 204 can be lifted and lowered through the guide plate 212. The compression spring 213 is sleeved on the outer peripheral wall of the vertical rod 204. The top end of the compression spring 213 is connected to the pressure plate 211, and the bottom end is connected to the guide plate 212. The clamping arms 406 are all in a semi-circular arc or a semi-elliptical arc shape. The compression spring 213 provides elastic restoring force for the lifting component, which can push the lifting component to move upward quickly when clamped laterally, thereby accelerating the closing speed of the double-leaf door 201; the semi-circular or semi-elliptical clamping arm 406 can conform to the physiological contour of the cow's neck, making the clamping contact surface evenly expanded and the force distribution balanced, which can avoid damage to the cow's neck caused by local stress concentration.

[0049] like Figure 1 and Figure 5 As shown, the drive mechanism includes a mounting base 502, a drive motor 503, a rotating arm 504, and a connecting arm 505. The two ends of the mounting base 502 are respectively fixed to the two sides of the middle of the top of the frame 100. The drive motor 503 is fixed above the mounting base 502, and the power output end of the drive motor 503 passes through the mounting base 502 and is connected to the rotating arm 504 located below the mounting base 502. There are two connecting arms 505. One end of each connecting arm 505 is hinged to the two ends of the rotating arm 504, and the other end is connected to the top of the corresponding side panel window 501. The two sides of the bottom surface of the mounting base 502 are respectively provided with first sliding grooves 506 along the width direction of the frame 100. The top of the side panel window 501 is provided with a slider 507 that slides in cooperation with the first sliding grooves 506.

[0050] Specifically, the drive motor 503 outputs rotational torque, driving the rotating arm 504 to rotate circumferentially around the output shaft of the drive motor 503. The rotating arm 504 converts its rotational motion into lateral linear motion of the side panel windows 501 through the double connecting arms 505 hinged at both ends. The top slider 507 of the side panel window 501 and the first sliding groove 506 of the mounting base 502 form a sliding guide pair, which constrains and limits the movement direction of the side panel window 501, so that the side panel window 501 can only translate along the width direction of the frame 100, thereby realizing the synchronous clamping or releasing action of the two side panel windows 501. This linkage-type drive structure has strong synchronicity of action on both sides, which can ensure that the clamping force on the left and right sides of the cow's body is balanced and consistent, effectively avoiding the tilting and displacement of the cow's torso caused by unilateral force deviation.

[0051] like Figure 1 As shown, in this embodiment, the bottom surfaces of the frame 100 are provided with second sliding grooves 508 on both sides along the width direction of the frame 100, and the bottom surface of the side window 501 is provided with a pulley 514 that slides and engages with the second sliding groove 508. The bottom of the side window 501 adopts a rolling engagement structure between the pulley 514 and the second sliding groove 508, which reduces the frictional resistance of lateral movement and makes the side window 501 open and close more easily and smoothly.

[0052] like Figure 1 As shown, the bottom surface of the frame 100 is fixed with anti-fouling baffles 103 on the inner side of the two second slide grooves 508 respectively. The height of the anti-fouling baffles 103 is 3-5cm. The anti-fouling baffles 103 can prevent cow manure, urine and debris in the breeding environment from entering the interior of the second slide grooves 508, and prevent the accumulation of dirt from causing the pulleys 514 to get stuck and slide.

[0053] like Figure 1As shown, a belly bar 104 is fixedly installed in the middle of the front side of the frame 100 along the width direction of the frame 100. The outer wall of the belly bar 104 is detachably equipped with a protective pad (not shown in the figure). The belly bar 104 can restrict the cow from squatting and sitting, and force the cow to maintain an upright and stable posture, providing reliable body position protection for breeding operations such as artificial insemination and rectal pregnancy examination. The detachable protective pad adopts a flexible structure, which can buffer the rigid contact between the belly bar 104 and the cow's abdomen, avoid pressure and scratches on the cow's body, and greatly reduce the stress response of the cow during restraint.

[0054] like Figure 6 and Figure 7 As shown, the Baoding cangue also includes a stop bar 509. Each side panel window 501 has a strip hole 510 along the length of the frame 100. Several stop pieces 511 are arranged at intervals along the extension direction of the strip hole 510. The stop bar 509 can be selectively inserted between adjacent stop pieces 511, between the last stop piece 511 and the rear side wall of the strip hole 510, or between the foremost stop piece 511 and the front side wall of the strip hole 510, so as to achieve adjustable installation.

[0055] Specifically, the stop component 511 includes a right-angled trapezoidal plate 5110 and an anti-detachment end plate 5111 integrally provided on the long right-angled side of the plate 5110; the side plate window 501 is fixedly mounted on a strip plate 512 located directly above the strip hole 510, and the strip plate 512 has stepped holes 513 that mate with the stop component 511 one by one. The anti-detachment end plate 5111 slides up and down in the wide section of the stepped hole 513, and slides up and down in the narrow section of the stepped hole 513 with the plate 5110. The inclined side of the plate 5110 is close to the rear side of the strip hole 510.

[0056] In this embodiment, the stop bar 509, in conjunction with the strip hole 510 and multiple sets of stop components 511, can flexibly adjust its front and rear positioning positions along the length of the frame 100, adapting to cattle of different body lengths and growth stages. It effectively restricts the cattle from moving back and forth, butting and struggling, and, together with the neck fixing structure and body fixing structure 500, forms a comprehensive three-dimensional restraint, improving the stability of the cattle during breeding operations. The stop component 511 adopts a right-angled trapezoidal plate 5110 with a rear-positioned slanted side. After the stop bar 509 is inserted and limited, it forms a one-way self-locking structure, which can effectively resist the reverse force of the cattle's backward movement and prevent the stop bar 509 from accidentally loosening due to external impact. The anti-loosening end plate 5111, in conjunction with the stepped hole 513, plays a dual role in vertical sliding guidance and anti-loosening limitation of the stop component 511. When switching positions, pushing the stop bar 509 forward can quickly complete the position adjustment of the stop bar 509, making the operation simple and convenient.

The specific embodiments described are used to help understand the concept of the present invention. Derivations and modifications made by those skilled in the art based on the specific embodiments of the present invention also fall within the scope of protection of the present invention.
