Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, specifically a silent self-locking neck clamp. Background Technology

[0002] Large-scale dairy farms are equipped with a comprehensive herd management system. Herd feeding management is a crucial part of this system. In addition to providing high-quality feed, creating a relaxed feeding environment in the barn is also a key aspect of feeding management and an important reflection of dairy cow welfare.

[0003] Currently, the mainstream feeding equipment on dairy farms is the self-locking neck clamp. A high-performance self-locking neck clamp ensures that dairy cows can feed comfortably and freely. It provides sufficient head and neck movement space for dairy cows, avoids competition among them while feeding, effectively reduces feed waste, and allows farmers to easily carry out various management tasks for dairy cows.

[0004] During use, the neck clamp's swing arm has three positional states, enabling different states and functions. Switching between these states is achieved by manipulating the swing arm, rotating the control lever, and moving the pawls. Because the neck clamp is primarily made of metal, the actions involved in switching states—such as the swing arm tip colliding with the control lever support, friction between the control lever and its support, and friction between the swing arm tip and the frame—all generate noise. This noise source is very close to the cows' ears, affecting their mood, causing tension and anxiety, thus impacting herd stability. It can also lead to increased heart rate and pulse, elevated blood pressure, decreased appetite, weight loss, and other digestive problems, ultimately affecting milk production. Therefore, we propose a silent, self-locking neck clamp. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a silent self-locking neck clip. Multiple rubber parts are set in the positions where collisions and friction are likely to occur, which reduces noise generation, greatly improves the environment for dairy cows to eat, reduces the impact of noise on the physical and mental health of dairy cows, helps maintain the stability of the dairy cow herd, and ensures normal milk production of dairy cows. It can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a silent self-locking neck clamp, comprising a fixed frame and a control lever. An upper curved tube is fixedly mounted on the top of the fixed frame. Several control lever support seats are evenly arranged on the upper curved tube. The control lever is rotatably mounted on the inner side of the top of the control lever support seat. Several pairs of claws are evenly arranged on the control lever. The claws and control lever support seats are alternately arranged along the length of the control lever. Several fixed arms are evenly fixed between the upper curved tube and the bottom of the fixed frame. A swing arm support seat is fixedly mounted in the middle of the side surface of each fixed arm. A swing arm is hinged to the end of the swing arm support seat. A rubber sleeve is fitted onto the swing arm support seat. The rubber sleeve has two contact surfaces corresponding to the swing arm. A movable end matching the claws is mounted on the top of the swing arm. The movable end is movably fitted onto the outside of the upper curved tube. A rubber gasket is provided on the inner surface of the top of the movable end, and the rubber gasket contacts the surface of the upper curved tube.

[0007] As a preferred embodiment of this utility model, a nylon sleeve is installed on the inner side of the top of the control lever support, and the control lever is rotatably disposed inside the nylon sleeve.

[0008] As a preferred embodiment of this utility model, two nylon sleeves are provided, and semi-circular holes matching the control lever are opened on the opposite side surfaces of the two nylon sleeves. After the two nylon sleeves are sleeved on the control lever, they are fixed to the control lever support seat by bolts.

[0009] As a preferred embodiment of this utility model, the rubber sleeve includes two separable rubber blocks, which are fixedly mounted on the swing arm support by bolts.

[0010] As a preferred technical solution of this utility model, the top two sides of the movable end are connected by fixing bolts, and a rubber sleeve is sleeved on the outside of the fixing bolts.

[0011] As a preferred embodiment of this utility model, the fixed frame, the control lever, the upper curved tube, the swing arm, and the fixed arm are all hollow tubes, and the fixed frame, the control lever, the upper curved tube, the swing arm, and the fixed arm are all provided with a sound-absorbing filler layer inside.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: multiple rubber parts are set in positions prone to collision and friction. When the cows are feeding and after feeding, the swing arm rotates to different positions and contacts the two contact surfaces on the rubber sleeve, which greatly reduces the noise generated by the collision between the swing arm and the swing arm support during the switching of the swing arm state; when the swing arm rotates, the moving end slides on the upper curved tube, and the rubber pad can avoid the huge noise generated by the friction between the metal tubes, which greatly improves the environment when the cows are feeding, reduces the impact of noise on the cows' physical and mental health, helps maintain the stability of the cow herd, and ensures the normal milk production of the cows.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-10This utility model provides a technical solution: a silent self-locking neck clamp, including a fixed frame and a control lever 1. The top of the fixed frame is fixedly provided with an upper curved tube 7, and a plurality of control lever support seats 3 are evenly provided on the upper curved tube 7. The control lever 1 is rotatably disposed on the inner side of the top of the control lever support seat 3, and a plurality of pairs of claws 2 are evenly provided on the control lever 1. The claws 2 and the control lever support seats 3 are alternately arranged along the length direction of the control lever 1, that is, a pair of claws 2 are provided between two adjacent control lever support seats 3. In addition to fixing the control lever 1, the control lever support seats 3 also limit the movable end 11 of the swing arm 8, thereby ensuring that one swing arm 8 limits the cow in each pen.

[0026] Several fixed arms 10 are evenly fixed between the upper curved tube 7 and the bottom of the fixed frame. A swing arm support 4 is fixedly installed in the middle of the side surface of the fixed arm 10. A swing arm 8 is hinged to the end of the swing arm support 4. The swing arm 8 rotates around the hinge point to different states, thereby realizing different functions. For details, please refer to [reference needed]. Figure 1 Different position states of the middle swing arm 8.

[0027] A rubber sleeve 5 is fitted onto the swing arm support 4. The rubber sleeve 5 has two contact surfaces corresponding to the swing arm 8. When the cows are feeding and after feeding, the swing arm 8 rotates to different positions and contacts the two contact surfaces on the rubber sleeve 5, which greatly reduces the noise generated by the collision between the swing arm 8 and the swing arm support 4 during the switching of states.

[0028] The top of the swing arm 8 is equipped with a movable end 11 that matches the claw 2. When the control lever 1 drives the claw 2 to rotate to the lower side, the claw 2 can lock the movable end 11 or limit it. When the control lever 1 drives the claw 2 to rotate to the upper side or both sides, the movable end 11 is not restricted, the swing arm 8 can move freely, and the cow can feed freely.

[0029] The movable end 11 is movably sleeved on the outside of the upper curved tube 7. A rubber gasket 6 is provided on the inner surface of the top end of the movable end 11. The rubber gasket 6 is in contact with the surface of the upper curved tube 7. When the swing arm 8 rotates, the movable end 11 slides on the upper curved tube 7. The rubber gasket 6 can avoid the huge noise generated by friction between metal pipes.

[0030] This invention incorporates multiple rubber components in locations prone to collisions and friction, significantly improving the environment for dairy cows during feeding, reducing the impact of noise on their physical and mental well-being, helping to maintain the stability of the dairy herd, and ensuring normal milk production.

[0031] In a preferred embodiment, a nylon sleeve 9 is installed on the inner side of the top of the control lever support 3, and the control lever 1 is rotatably positioned inside the nylon sleeve 9, which reduces the noise generated when the control lever 1 rotates, and further reduces the impact of noise on the physical and mental health of dairy cows.

[0032] In a further preferred technical solution, two nylon sleeves 9 are provided. The opposite side surfaces of the two nylon sleeves 9 are each provided with a semi-circular hole that matches the control lever 1. After the two nylon sleeves 9 are fitted onto the control lever 1, they are fixed to the control lever support 3 by bolts. The rubber sleeve 5 also includes two separable rubber blocks. The two rubber blocks are fixed to the swing arm support 4 by bolts. Since nylon and rubber products are polymer materials, their service life is different from that of metal products. Especially in the pasture environment, the service life of polymer materials is shorter. Therefore, both the nylon sleeve 9 and the rubber sleeve 5 are designed to be detachable and easy to replace, so that they can be replaced when they are damaged and can no longer effectively provide noise reduction function, thus ensuring a good foraging environment.

[0033] In a preferred embodiment, the top two sides of the movable end 11 are connected by fixing bolts, and a rubber sleeve 12 is sleeved on the outside of the fixing bolts. When the movable end 11 slides on the upper curved tube 7, it contacts and rubs against the upper curved tube 7 through the rubber sleeve 12, which further reduces the noise generated by friction between metal parts.

[0034] In an optional technical solution, the fixed frame, control lever 1, upper curved tube 7, swing arm 8, and fixed arm 10 are all hollow tubes, which can reduce the production cost and overall weight of the neck clamp. Since the hollow tube can act as a resonance cavity to amplify and increase the intensity of noise when noise is generated, a sound-absorbing filler layer 13 is provided inside the fixed frame, control lever 1, upper curved tube 7, swing arm 8, and fixed arm 10. The sound-absorbing filler layer 13 is preferably a commonly used glass wool filler layer, slag wool filler layer, or metal fiber wool layer. These materials can fill the inside of the tube, preventing the formation of a resonance cavity. At the same time, glass wool, slag wool, and metal fiber wool have good sound absorption properties; they achieve noise reduction by converting sound energy into heat energy. The materials contain a large number of tiny pores; when sound waves enter these pores, they cause the air molecules on the pore walls to vibrate and generate heat through friction, thus consuming sound energy. Furthermore, these fillers also have good heat resistance and chemical stability, making them suitable for aquaculture environments.

[0035] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
