Description

Technical Field

[0001] This utility model relates to the field of dairy farming technology, specifically to a quick-release and reassembly control lever connector for dairy cow neck clamps. Background Technology

[0002] In large-scale dairy farms, dairy cow feeding management is a core aspect of ensuring animal welfare and production efficiency. Neck clips are essential equipment during dairy cow feeding. They use a self-locking mechanism to secure the cow's head, ensuring safe and comfortable feeding. Neck clips also prevent cows from fighting over feed, reducing feed waste. Furthermore, neck clips can assist with routine procedures such as veterinary examinations and vaccinations.

[0003] The core components of a neck clamp include a frame, a swing arm, grippers, and a control lever. The control lever can control the synchronous opening and closing of multiple neck clamps. There are two common methods for connecting control levers:

[0004] One method involves necking one end of the control lever during production. During on-site installation, the necked end of one control lever is inserted into the unnecked end of an adjacent control lever, and then welded together at the joint. The advantage of this method is a strong connection. The disadvantages are: complex installation (requiring professional welders, increasing labor and time costs); difficult maintenance (requiring cutting the weld joint when damaged, inconvenient operation); and non-adjustable (unable to flexibly adjust the neck clamp length when the ranch layout changes).

[0005] Another method involves necking one end of the joystick and drilling a mounting hole at both the necked and unnecked ends. During on-site installation, the necked end of one joystick is inserted into the unnecked end of the adjacent joystick, and then secured with a bolt through the mounting hole. The advantage of this method is its ease of operation. The disadvantages are weak torsional resistance: the joystick can easily rotate after the bolt loosens, causing misalignment of the pawls; and it is difficult to adjust. Utility Model Content

[0022] 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.

[0023] Example 1, please refer to Figure 1-3This utility model provides a technical solution: a quick-release and detachable lever connector for a cow neck clamp, including a neck clamp main frame 1. An upper fixed rod 4 is fixedly mounted on the neck clamp main frame 1. Several lever support seats are evenly arranged on the upper fixed rod 4. A lever 2 is rotatably mounted on the inner side of the top of each lever support seat. Several pairs of claws 3 are evenly arranged on the lever 2. Several fixed arms 6 and several swing arms 5 are evenly arranged on the upper fixed rod 4. A swing arm support seat is fixedly mounted on the middle of the side surface of each fixed arm 6. The middle of each swing arm 5 is hinged to the swing arm support seat, allowing the swing arm 5 to rotate around the hinge point to adjust its position, facilitating different limiting functions for the cow. A movable seat is movably fitted onto the upper fixed rod 4 at the top of each swing arm 5, limiting its top position when the swing arm 5 rotates.

[0024] Adjacent joysticks 2 are connected by joystick connectors 7, which include two semi-cylindrical sleeves 8. The ends of adjacent joysticks 2 are clamped inside the two ends of the two sleeves 8. The joysticks 2 do not need to be necked. Adjacent joysticks 2 are connected by clamping the two sleeves 8.

[0025] The sleeve 8 is equipped with an adjustable fixing component, which allows for easy adjustment of the distance between two adjacent control levers 2, suitable for different connection situations. Installation is simple and maintenance is convenient. Furthermore, the neck clamp assembly length can be flexibly adjusted when the ranch layout changes.

[0026] In a preferred embodiment, a semi-annular anti-slip pad 9 is provided on the inner surface of the sleeve 8. The anti-slip pad 9 is made of commonly used rubber pads, which can play an anti-slip role while providing cushioning protection for the surfaces of the sleeve 8 and the control lever 2. Furthermore, it can increase friction by pressing the anti-slip pad 9 when fixed.

[0027] In a further preferred embodiment, the inner surface of the anti-slip mat 9 is uniformly provided with anti-slip grooves, which can further improve the anti-slip performance of the anti-slip mat 9.

[0028] In a preferred embodiment, the fixing assembly includes elongated holes 10 at both ends of the side surfaces of the two sleeves 8. A through hole corresponding to the elongated hole 10 is provided at the end of the control lever 2. A fixing bolt 11 is installed in the elongated hole 10 and the through hole. A fixing nut 12 is threaded to the end of the fixing bolt 11. During installation, through holes can be made at corresponding positions at the ends of the control levers 2 according to the connection length and pasture layout. After connecting the two control levers 2, the two sleeves 8 are fitted onto the connection point. The fixing bolt is passed through the elongated hole on the upper sleeve 8, then through the through hole on the control lever 2, and finally out from the lower side of the elongated hole on the lower sleeve 8. The fixing nut 12 is then tightened to fix the two control levers 2. This method is convenient and simple to operate. When adjustment is needed, the nut is loosened, and the relative positions of the control lever 2 and the sleeve 8 are adjusted. The neck clamp length can be flexibly adjusted when the pasture layout changes.

[0029] In a further preferred embodiment, a countersunk hole 13 is formed at the elongated hole 10 on the sleeve 8. The length and width of the countersunk hole 13 are both greater than those of the elongated hole 10, and the depth of the countersunk hole 13 is one-third to one-quarter of the wall thickness of the sleeve 8. A retaining groove 14 is uniformly formed on the inner upper surface of the countersunk hole 13. A retaining block 15 is provided inside the countersunk hole 13. The lower surface of the retaining block 15 is uniformly formed with retaining teeth corresponding to the retaining groove 14, and a through hole corresponding to the fixing bolt 11 is formed on the retaining block 15. After the fixing bolt 11 passes through the through hole on the retaining block 15, it enters the elongated hole 10. When the fixing bolt 11 is tightened by the fixing nut 12, the fixing bolt 11 also presses the retaining block 15 against the retaining groove 14 of the countersunk hole 13, causing the retaining teeth to mesh with the retaining groove 14, thereby improving the fixing firmness of the fixing bolt 11 on the sleeve 8 and the operating lever 2.

[0030] Example 2, please refer to Figure 4-5 This utility model also provides another technical solution. This embodiment is largely the same as the first embodiment, except that: the fixing component includes two quick-release rings 18 disposed at both ends of the sleeve 8. The outer surfaces of both ends of the sleeve 8 are provided with semi-annular grooves 16 corresponding to the quick-release rings 18. The outer surfaces of the quick-release rings 18 are provided with protrusions. A notch is provided on one side of the quick-release rings 18 corresponding to the protrusions. Connecting blocks 19 are fixedly disposed on the outer surfaces of the upper and lower sides of the notch. The connecting blocks 19 protrude outwards. The two connecting blocks 19 are provided with corresponding through holes. A tensioning bolt 20 is disposed in the through hole. The top end of the tensioning bolt 20 is hinged to the end of the arc-shaped rotating member 21. The end of the rotating member 21 connected to the tensioning bolt 20 includes an arc surface for tightening the tensioning bolt 20 and a flat surface for loosening the tensioning bolt 20. An adjusting nut 23 is threadedly connected to the bottom end of the tensioning bolt 20 for adjusting the tightness of the quick-release rings 18. In use, first attach the two quick-release rings 18 to the two operating levers 2, then attach the two sleeves 8 one above the other to the ends of the two operating levers 2. Connect the two operating levers 2 and adjust the distance. Then, move the two quick-release rings 18 onto the semi-annular grooves 16 of the sleeves 8 in sequence. Next, rotate the rotating part 21 to rotate it away from the tension bolt 20, so that its arc surface contacts the upper surface of the connecting block 19. This will tighten the tension bolt 20, thereby tightening the quick-release rings 18 and fixing the upper and lower sleeves 8. Then, operate the other quick-release ring 18 in the same way. Compared with Embodiment 1, no tools are needed for disassembly and adjustment; it can be adjusted manually, making the operation simpler.

[0031] In a preferred embodiment, the other end of the rotating component 21 is provided with a toggle block 22 corresponding to the protrusion. The toggle block 22 protrudes slightly from the protrusion, making it more convenient to operate the rotating component 21 to open or tighten.

[0032] In a further preferred technical solution, the outer surface of the semi-annular groove 16 is uniformly provided with several rubber protrusions 17. When the quick-release ring 18 is tightened, it can compress the protrusions 17 to deform, increase the relative friction, and thus increase the clamping force of the quick-release ring 18 on the two sleeves 8, while also protecting the surfaces of the sleeves 8 and the quick-release ring 18.
