Description

Technical Field

[0001] This utility model relates to the field of cow neck yoke technology, and in particular to a cow neck yoke with cushioning protection. Background Technology

[0002] A cow neck yoke is a special device installed at the junction of the feeding passage and the living area in a dairy farm. It is used to restrict the movement of the cow's neck through a movable rod assembly to achieve fixation.

[0003] Chinese Patent Publication No. CN222997948U discloses a cow neck yoke, which consists of a lower frame, an upper frame, detachable end plates, and a vertical frame fixed between the lower and upper frames. By pushing a single-sided extension rod, a rack slides within the upper frame. A middle gear drives another rack to retract synchronously. During this process, the rack compresses a spring and, through a limiting strip, drives a sliding rod to slide along an arc-shaped hole, causing the clamp, clamp rod, and locking rod to rotate around the hinge point between the clamp rod and the horizontal frame. When the locking rod rotates, it presses against the locking head, causing the locking head to rotate around its own hinge point. After the locking rod passes the locking head, the locking head falls due to its own weight, and its bottom prevents the locking rod from reversing back to its original position. Ultimately, multiple sets of clamp rods can be rotated and erected by pushing from one side, eliminating the need for personnel to manually straighten each clamp rod.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the existing cattle neck yoke lacks an effective buffer structure, which causes the clamping force of the clamping bar on the cattle's neck to act directly on the cattle's neck skin and muscles. If the cattle are not in the correct position or other special circumstances occur, excessive impact can easily occur. At the same time, if the cattle struggle due to stress response, it can easily cause abrasions and muscle contusions on the cattle's neck skin, which not only affects the cattle's health and feeding enthusiasm, but also affects the cattle's lifespan. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology of cattle neck yoke lacks a buffer protection structure, which makes it easy to pinch and injure cattle. Therefore, we propose a cattle neck yoke with buffer protection.

[0006] To achieve the above objectives, this application adopts the following technical solution: a cow neck yoke with buffer protection, comprising: a base frame and an upper frame, and several cow partitions fixedly installed between the base frame and the upper frame. Each cow partition is provided with two partition bars inside, and crossbars are provided on opposite sides of the two partition bars. Each crossbar is hinged with a clamping bar inside, and a limit bar is provided on the outer surface of each clamping bar. A buffer component for preventing the cow from being pinched is provided on the outer surface of each clamping bar. A locking component is provided on the upper surface of the upper frame. The buffer assembly includes an elastic steel ring fitted on the outer surface of each set of clamping bars, and a buffer pad fitted on the outer surface of the elastic steel ring. Each set of crossbars has a movable groove at the bottom, and a spring damper is installed on the inner wall of each set of movable grooves. An arc-shaped block is installed at the bottom of each set of spring dampers. One end of each set of limiting rods contacts the bottom of the corresponding arc-shaped block. Each set of cattle isolation areas has symmetrically arranged limiting protrusions inside. The bottom of each set of limiting protrusions is fixed to the upper surface of the base frame to prevent cattle from being pinched.

[0007] Preferably, both sides of each set of buffer pads are fixed to the outer surface of the clamping rod by clamps, which facilitates the replacement of the buffer pads.

[0008] Preferably, each set of cushioning pads has a honeycomb-shaped silicone pad integrally molded on the side facing the cow's neck, which improves the comfort of the cow's neck and reduces the risk of pinching injury.

[0009] Preferably, each set of clamping rods has a connecting seat on its upper surface, and each set of connecting seats has a limiting post A inside. A cavity is provided between the connecting seat and the limiting post A, and the upper frame is located in the cavity to avoid the opening and closing angle between the two sets of clamping rods being too large or too small.

[0010] Preferably, the locking assembly includes a support column fixedly installed on the upper surface of the upper frame, a rotating rod that passes through the inside of the support column, and a rotating handle fixedly installed at one end of the rotating rod. Each cattle partition is symmetrically provided with lock heads. The outer surface of the rotating rod is hinged to the middle of each lock head. Each lock head has two sets of limiting posts B inside. The rotating rod is located between the two sets of limiting posts B and is used to lock or unlock the cattle.

[0011] Preferably, each clamp bar is equipped with an anti-slip pad at the bottom, with the bottom of the anti-slip pad in contact with the upper surface of the base frame, to prevent the clamp bar from slipping and causing the limiting effect on the cattle's neck to fail or to cause injury.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, each cattle-separating zone in the device is used to accommodate only one cow. Taking this as an example, since the crossbar on the opposite side of the separating rod provides hinge support for the clamping rod, the clamping rod can rotate around the crossbar. Therefore, in the normal state where no cow is entering, it is in an open or closed state, and the limiting protrusion in the cattle-separating zone can prevent excessive opening and closing. When a cow enters between the two sets of clamping rods, it will collide with the clamping rod located below the hinge, causing the clamping rod located below the hinge to move towards the center, thereby fixing the cow's neck. Since the outer surface of the clamping rod is provided with an elastic steel ring and a buffer pad, it can absorb the impact force and prevent the cow from being pinched. At the same time, the limiting rod on the outer surface of the clamping rod contacts and presses against the arc-shaped block in the movable groove at the bottom of the crossbar. Since the arc-shaped block will press against the spring damper, the spring damper will further absorb the impact force through its own elastic deformation buffering force, preventing the cow from being pinched.

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Reference Figure 1 As shown, this utility model provides a technical solution: a cow neck yoke with buffer protection, including: a base frame 1 and an upper frame 2, and several cow-separating areas 3 fixedly installed between the base frame 1 and the upper frame 2. Each group of cow-separating areas 3 is provided with two separating rods 4 inside, and crossbars 5 are provided on opposite sides of the two groups of separating rods 4. Each group of crossbars 5 is hinged with clamping rods 6 inside, and each group of clamping rods 6 is provided with limiting rods 61 on the outer surface. Each group of clamping rods 6 is provided with a buffer component 7 for preventing the cow from being pinched. The upper surface of the upper frame 2 is provided with a locking component 8.

[0017] Reference Figures 1-3As shown, in this embodiment: the buffer assembly 7 includes an elastic steel ring 71 sleeved on the outer surface of each set of clamping rods 6, and a buffer pad 72 sleeved on the outer surface of the elastic steel ring 71. Each set of crossbars 5 has a movable groove 73 at its bottom, and a spring damper 74 is provided on the inner wall of each set of movable grooves 73. An arc-shaped block 75 is provided at the bottom of each set of spring dampers 74. One end of each set of limiting rods 61 contacts the bottom of the corresponding arc-shaped block 75. Each set of cattle-separating areas 3 has symmetrically arranged limiting protrusions 76 inside, and the bottom of each set of limiting protrusions 76 is fixed to the upper surface of the base frame 1. The lengths of the base frame 1 and the upper frame 2 are customized according to actual needs, and several cattle-separating areas 3 are divided to separate cattle and avoid mutual interference. Since the crossbars 5 on the opposite side of the separating rods 4 provide hinged support for the clamping rods 6, allowing the clamping rods 6 to rotate around the crossbars 5, under normal conditions when no cattle are entering, it provides a buffer for the clamping rods 6. Figure 1 The right side is in an open / closed state, and the limiting protrusion 76 in the cattle separation area 3 can prevent excessive opening and closing; when a cow enters between the two sets of clamping rods 6, it will collide with the clamping rod 6 located below the hinge, and the clamping rod 6 located below the hinge will move towards the center, thereby fixing the cow's neck. Since the outer surface of the clamping rod 6 is provided with an elastic steel ring 71 and a buffer pad 72, it can absorb the impact force and prevent the cow from being pinched. At the same time, the limiting rod 61 on the outer surface of the clamping rod 6 contacts and presses the arc-shaped block 75 in the movable groove 73 at the bottom of the crossbar 5. Since the arc-shaped block 75 will press the spring damper 74, the spring damper 74 will further absorb the impact force through its own elastic deformation buffering force, preventing the cow from being pinched.

[0018] Both sides of each set of buffer pads 72 are fixed to the outer surface of the clamping rod 6 by clamps 721, which facilitates the cleaning, replacement and maintenance of the buffer pads 72 and prevents the buffer pads 72 from shifting during use.

[0019] Each set of cushioning pads 72 has a honeycomb-shaped silicone pad integrally molded on the side facing the cow's neck. When the cow's neck comes into contact with the cushioning pad 72, it can better conform to the curve of the cow's neck, thereby improving the comfort of the cow's neck and reducing the risk of pinching injury.

[0020] Each set of clamping rods 6 has a connecting seat 62 on its upper surface. Each set of connecting seats 62 has a limiting post A63 inside. There is a cavity between the connecting seat 62 and the limiting post A63. The upper frame 2 is located in the cavity to prevent the opening and closing angle between the two sets of clamping rods 6 from being too large or too small.

[0021] The locking assembly 8 includes a support column 81 fixedly mounted on the upper surface of the upper frame 2, a rotating rod 82 penetrating inside the support column 81, and a rotating handle 83 fixedly mounted at one end of the rotating rod 82. Each cattle partition 3 has symmetrically arranged lock heads 84. The outer surface of the rotating rod 82 is hinged to the middle of each lock head 84. Each lock head 84 has two sets of limiting posts B85 inside. The rotating rod 82 is located between the two sets of limiting posts B85. The rotating handle 83 drives the rotating rod 82 to rotate, causing all lock heads 84 to flip from an unlocked state parallel to the clamping rod 6 to a locked state perpendicular to the clamping rod 6. When a cow enters the cattle partition 3 and impacts the clamping rod 6, The clamping rod 6 moves toward the center of the cattle-separating area 3. The connecting seat 62 on the upper surface of the clamping rod 6 pushes the lock head 84 to rotate and tilt around the rotating rod 82, so that the connecting seat 62 can pass through one side of the lock head 84. After the connecting seat 62 passes through, the lock head 84 quickly returns to a vertical state under its own gravity. At this time, one side of the lock head 84 abuts against the connecting seat 62, restricting the clamping rod 6 from moving outwards from the cattle-separating area 3, thus locking the clamping rod 6. In addition, when unlocking, a single set of clamping rods 6 can be unlocked and cattle released by manually flipping a single lock head 84, or by rotating the handle 83 to drive the rotating rod 82 to rotate, causing all lock heads 84 to rotate synchronously to a parallel state, thus unlocking and releasing multiple sets of clamping rods 6 as a whole.

[0022] Each clamping bar 6 is equipped with an anti-slip pad 64 at its bottom. The bottom of the anti-slip pad 64 is in contact with the upper surface of the base frame 1. The anti-slip pad 64 can increase the friction between the clamping bar 6 and the base frame 1, and prevent the clamping bar 6 from slipping, which could lead to failure of the clamping limit on the cattle's neck or cause injury.

[0023] Working principle: Before cattle enter, the clamps 6 in each cattle isolation zone 3 are in a state of... Figure 1The opening and closing state shown on the right is limited by the limiting protrusions 76 symmetrically arranged in the cattle isolation area 3 to prevent the clamping rods 6 from opening and closing excessively. Furthermore, the connecting seat 62 on the upper surface of each set of clamping rods 6 and the limiting post A63 inside the connecting seat 62 allow the connecting seat 62 to move on the outer surface of the upper frame 2, thereby avoiding the opening and closing angle between the two sets of clamping rods 6 being too large or too small. In addition, the anti-slip pads 64 at the bottom of the clamping rods 6 are in close contact with the upper surface of the base frame 1, thereby preventing the clamping rods 6 from sliding and causing the limiting of the cattle's neck to fail or causing pinching injury. At the same time, all the locks 84 in the locking assembly 8 are in an unlocked state parallel to the clamping rods 6 under the action of the initial position of the rotating rod 82, preparing for the cattle to enter the cattle isolation area 3. When cattle enter different isolation zones 3, their heads or bodies will collide with the clamping rods 6 located below the hinge. Since the clamping rods 6 are hinged inside the crossbar 5, under the action of the collision force, the clamping rods 6 located below the hinge will move around the crossbar 5 towards the center of the isolation zone 3, and begin to initially limit the cattle's neck. During the above process, the outer surface of the clamping rods 6 is fitted with an elastic steel ring 71 and a buffer pad 72. The elastic steel ring 71 first absorbs part of the collision impact force through its own elastic deformation. Then the buffer pad 72 contacts the cattle's neck. The buffer pad 72 is an integrally formed honeycomb silicone pad facing the side of the cattle's neck, so it can better fit the curve of the cattle's neck, which not only improves the comfort of the cattle's neck, but also further disperses and absorbs the impact force, effectively preventing the cattle from being pinched. In addition, the buffer pad 72 is fixed to the outer surface of the clamping rod 6 on both sides by clamps 721, which prevents the buffer pad 72 from shifting during the buffering process and ensures the stability of the buffering effect. Also, when clamping the cattle, the limiting rod 61 on the outer surface of the clamping rod 6 will contact the arc-shaped block 75 in the movable groove 73 at the bottom of the crossbar 5 and generate compression. After being compressed, the arc-shaped block 75 will move into the movable groove 73, thereby compressing the spring damper 74 set in the inner wall of the movable groove 73. Therefore, through the elastic deformation of the spring damper 74 itself, the force transmitted by the limiting rod 61 can be further buffered, and the impact force can be absorbed again, forming a double buffer protection, which greatly reduces the risk of clamping and injuring cattle. Finally, by rotating the handle 83 to drive the rotating rod 82 to rotate, all the lock heads 84 can be rotated from the unlocked state parallel to the clamping rod 6 to the locked state perpendicular to the clamping rod 6. When a cow enters the cattle isolation zone 3 and hits the clamping rod 6, the clamping rod 6 moves towards the center of the cattle isolation zone 3. The connecting seat 62 on the upper surface of the clamping rod 6 pushes the lock head 84 to rotate and tilt around the rotating rod 82, so that the connecting seat 62 can pass through one side of the lock head 84. After the connecting seat 62 passes through, the lock head 84 quickly returns to the vertical state under its own gravity. At this time, one side of the lock head 84 abuts against the connecting seat 62, restricting the clamping rod 6 from moving outward from the cattle isolation zone 3, thus locking the clamping rod 6. In addition, when unlocking, a single lock head 84 can be manually rotated to unlock and release a single set of clamping rods 6, or the rotating handle 83 can be used to drive the rotating rod 82 to rotate, causing all the lock heads 84 to rotate synchronously to the parallel state, thus unlocking and releasing multiple sets of clamping rods 6 as a whole.

[0024] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
