Abstract
Description
Technical Field
[0001] This utility model relates to the field of animal husbandry technology, and in particular to a device for preventing pinching injuries to dairy cows' neck yokes. Background Technology
[0002] Cow neck yokes are core facilities in modern dairy farming that improve management efficiency and ensure animal welfare, serving multiple dimensions including behavior management, health protection, and production optimization. Specifically, cow neck yokes use self-locking devices to secure the cow's head, ensuring safety and facilitating veterinarians' procedures such as immunization, pregnancy checks, and artificial insemination, while reducing the risk of injury to personnel. During feeding, each cow is kept in its own pen to prevent competition for food.
[0003] A search revealed Chinese patent application number 202322490055.2, which discloses an unlocking device for an animal neck clamp and the animal neck clamp itself. The animal neck clamp includes a control lever, a claw assembly, and a swing arm assembly, with the claw assembly and swing arm assembly corresponding one-to-one. Each claw assembly includes two claws mounted on the control lever, forming a clamping space between the two claws for holding the corresponding swing arm assembly. The unlocking device includes a lever and an opening portion at one end of the lever. The opening portion is designed to extend between the two claws to expand the clamping space and thus unlock the swing arm assembly. This invention provides an unlocking device for an animal neck clamp, employing a lever and an opening portion at the end of the lever. This allows the operator to unlock a specific swing arm assembly from a relatively distant position, making it ideal for individually unlocking specific sick cows for targeted treatment. It avoids startling the cows and the risk of the operator's hand being pinched, and it does not affect the feeding of other cows.
[0004] While the aforementioned patent allows for the individual unlocking of a swing arm component from a relatively distant location to prevent the cow from being startled, the width of its restraint area is not easily adjustable, which can easily lead to the cow being pinched due to its narrow width during use.
[0005] Therefore, there is an urgent need for a device to prevent cows from being pinched by neck yokes in order to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to solve the problem that the restraint area of a cow's neck is inconvenient to adjust and is prone to pinching and injuring the cow due to its width in the existing technology, and to propose a cow neck yoke anti-pinch device.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A device for preventing pinching injuries to cows using neck yokes includes two parallel-mounted first and second support seats. Multiple constraint components and a second upright located on one side of the constraint components are disposed between the first and second support seats. A buffer rod is connected to one side of the second upright via a spring buffer component. Multiple first rails are fixedly mounted on the other side of the second upright. A first slider is fixedly mounted on the top of the second upright, and a second slider is fixedly mounted on the bottom of the second upright. A groove for sliding the second slider is formed on the top of the first support seat, and a groove for sliding the first slider is formed on the bottom of the second support seat. A screw is rotatably mounted inside the second support seat, and the first slider is threadedly connected to the screw.
[0009] As a preferred technical solution of this application, the constraint component includes a first upright connecting the first support base and the second support base. A bracket is fixedly installed on the side of the first upright, the outer end of the bracket is rotatably connected to the middle of the movable limiting rod, a U-shaped clip is fixedly installed on the top of the movable limiting rod, and a second railing is installed on the lower side of the movable limiting rod.
[0010] As a preferred technical solution of this application, a movable rod is rotatably mounted on the top of the second support base, and the movable rod is provided with a plurality of butterfly locks corresponding to the movable limit rod.
[0011] As a preferred technical solution of this application, an unlocking handle is installed at one end of the movable rod.
[0012] As a preferred technical solution of this application, the inner side of the butterfly lock is rotatably connected with a collar, the top of the collar is threaded with a fastening screw, and the collar is sleeved on the movable rod.
[0013] As a preferred technical solution of this application, the spring buffer assembly includes a buffer connecting rod fixedly connected to the buffer rod and a mounting hole installed on the second upright. The buffer connecting rod is connected to the interior of the mounting hole through a buffer spring.
[0014] As a preferred technical solution of this application, a rotating knob is fixedly installed on the outer end of the screw.
[0015] Compared with the prior art, this utility model provides a device to prevent pinching injuries to cow neck yokes, which has the following beneficial effects:
[0016] 1. The cow neck yoke anti-pinch device, through the first and second sliders set at both ends of the second upright, allows the second upright to slide within a range between the second support and the first support, facilitating adjustment of the restraint area. The width of the restraint area can be quickly adjusted by rotating the knob according to the cow's needs, and the cow is prevented from being pinched by the appropriate width. This solves the problem in the prior art that the restraint area of the cow's neck is not easy to adjust and the cow is easily pinched due to the width.
[0017] 2. The anti-pinch device for cow neck yokes features a buffer bar installed on one side of the second upright post. The buffer bar is connected to the second upright post via a spring buffer assembly. When the cow collides with the buffer bar during use, the spring buffer assembly can cushion the impact, reducing rigid collisions and lowering the risk of collisions for the cow. This solves the problem in the prior art where the cow is prone to colliding with the second upright post, resulting in surface damage. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] Example:
[0027] Reference Figures 1-5 A device for preventing cow neck yoke injuries includes two parallel-installed first support bases 1 and second support bases 8. Multiple restraint components and a second upright 10 located on one side of the restraint components are arranged between the first support bases 1 and the second support bases 8. The restraint components include a first upright 2 connecting the first support bases 1 and the second support bases 8. A bracket 3 is fixedly installed on the side of the first upright 2. The outer end of the bracket 3 is rotatably connected to the middle of a movable limiting rod 4. A U-shaped clip 13 is fixedly installed on the top of the movable limiting rod 4. A second fence 18 is installed on the lower side of the movable limiting rod 4. The second fence 18 can fill the gap between the lower part of the movable limiting rod 4 and the first upright 2, preventing cows from accidentally entering the passage when eating, making it safer to use.
[0028] The top of the second support base 8 is rotatably mounted with a movable rod 7. The movable rod 7 is equipped with multiple butterfly locks 9 corresponding to the movable limit rod 4. When the cows are feeding, the movable limit rod 4 is rotated and locked into the side of the butterfly lock 9 through the U-shaped card 13. At this time, the movable limit rod 4 is parallel to the second upright rod 10, which restrains the cow's neck, making it easier for the cows to feed independently and preventing them from fighting for food. One end of the movable rod 7 is equipped with an unlocking handle 6. When unlocking, the butterfly lock 9 can be flipped over by rotating the unlocking handle 6, thus unlocking the movable limit rod 4. The operation is simple and convenient.
[0029] A buffer rod 12 is connected to one side of the second upright post 10 via a spring buffer assembly. The buffer rod 12 can reduce the noise when the cows collide during use and buffer the collision when the cows are eating, thereby reducing the damage to the cows and effectively preventing the cows from being pinched. Multiple first fences 11 are fixedly installed on the other side of the second upright post 10. The first fences 11 can fill the side space of the second upright post 10 to prevent the cows from entering the wrong feeding position.
[0030] Reference Figure 1 and Figure 2Furthermore, the inner side of the butterfly lock 9 is rotatably connected to a collar 14, and the top of the collar 14 is threaded with a fastening screw 15. The collar 14 is sleeved on the movable rod 7. During use, the installation position of the butterfly lock 9 can be quickly adjusted by adjusting the position of the collar 14, making it more convenient and faster to use.
[0031] Reference Figure 4 and Figure 5 Furthermore, the spring buffer assembly includes a buffer link 20 fixedly connected to the buffer rod 12 and a mounting hole installed on the second upright 10. The buffer link 20 is connected to the inside of the mounting hole through a buffer spring 21. When the buffer rod 12 receives a collision, the buffer link 20 compresses the buffer spring 21, effectively preventing rigid collision between the cow's neck and the buffer rod 12, and preventing the cow from being pinched during use.
[0032] Reference Figure 1 , Figure 3 and Figure 4 Furthermore, a first slider 16 is fixedly installed at the top of the second upright 10, and a second slider 19 is fixedly installed at the bottom of the second upright 10. A groove for sliding the second slider 19 is opened at the top of the first support base 1, and a groove for sliding the first slider 16 is opened at the bottom of the second support base 8. A screw 17 is rotatably installed inside the second support base 8, and a rotating knob 5 is fixedly installed at the outer end of the screw 17. The first slider 16 is threadedly connected to the screw 17. By rotating the rotating knob 5, the first slider 16 is moved, thereby adjusting the position of the second upright 10. In use, the distance between the second upright 10 and the movable limit rod 4 can be adjusted according to the neck needs of the cow to prevent the cow from being pinched due to mismatched width. During adjustment, the position of multiple second uprights 10 can be adjusted by rotating the screw 17, making the operation simple and convenient.
[0033] Specifically, when using this anti-pinch device for cow neck yokes: After installation, adjust the position between the multiple second uprights 10 by rotating the knob 5 and the screw 17. After adjustment, when the cow is feeding, it enters between the movable limit rod 4 and the second uprights 10, and then presses the lower part of the movable limit rod 4 to make it rotate. The movable limit rod 4 is then engaged with one side of the butterfly lock 9 through the top U-shaped clip 13, which is in a restrained state. After feeding, rotate the unlocking handle 6 to make the butterfly lock 9 rotate and disengage from the U-shaped clip 13, releasing the restraint. At this time, the cow can leave freely.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
