Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixing devices, and in particular to a fixing device for skinning sheep. Background Technology
[0002] In the slaughtering and processing of mutton sheep, skinning is a crucial step that directly affects the quality and hygiene of the final product. Restraining the sheep's limbs is a fundamental step in the skinning process for several reasons: First, mutton sheep may still experience slight twitching or movement during post-slaughter processing due to nerve reflexes or manipulation. Without effective restraint, the animal's movement increases the difficulty of the process, potentially causing injury to workers or unnecessary skin tears, affecting the integrity of the skinning. Second, the skinning process typically begins with the limbs and gradually extends towards the torso. Restraining the limbs ensures even stretching of the skin, preventing damage to the leather or residual fascia due to uneven local tension, which would affect subsequent processing efficiency and the commercial value of the leather. Furthermore, restraint improves operational efficiency. In large-scale slaughterhouses, stable restraint reduces processing time, ensures a smooth skinning process, reduces worker fatigue, and guarantees workplace safety and standardization.
[0003] However, existing techniques for securing and fixing sheep during skinning have significant shortcomings. Traditional devices often rely on manual mechanical structures, such as simple ropes or rigid clamps. These methods are often not secure enough to effectively suppress the sheep's slight movements, leading to skin slippage or displacement during skinning and increasing the risk of operational errors. Furthermore, existing equipment generally lacks size adaptability. Different breeds and growth stages of sheep vary significantly in size (e.g., adult sheep versus lambs), but most securing devices cannot be easily adjusted in width or height. Operators need to frequently change clamps or make manual adjustments, which not only prolongs preparation time but may also cause limb injuries or skin bruises due to forced fixation. Therefore, a new sheep skinning and fixing device is proposed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a sheep skinning and fixing device that can easily fix the limbs of sheep of different sizes, making it convenient to skin them, and can effectively solve the problems in the background art.

This not only allows for quick adaptation to the limb widths of sheep of different breeds and sizes, but also ensures stability and consistency during the fixing process, avoiding skin tearing or operational interruptions caused by size mismatches in traditional clamps. Simultaneously, the worm gear transmission system and anti-slip groove design built into the fixing component, driven by the motor of the rotating component, provide a uniform and reliable clamping force, effectively suppressing minor movements of the sheep during the skinning process, thereby reducing operational risks and improving skinning integrity.

[0020] The working principle of the sheep skinning and fixing device provided by this utility model is as follows: First, the telescopic arm of the first hydraulic rod 21 of the adjusting component 2 pushes the sliding frame 22 to slide on the side of the mounting strip 1, thereby driving the connecting rod 23 and the connecting box 24 to move laterally, thereby adjusting the distance between the two fixing components 3 to adapt to the width requirements of sheep of different sizes; then, the sheep's limbs are placed inside the four fastening frames 31, and then the motor 51 is started to make the gear 52 rotate, which drives the connecting column 42 to rotate. The rotation of the connecting column 42 drives the two worm gears 44 to rotate, which drives the two worm wheel rings 33 to rotate. The rotation of the worm wheel rings 33 drives the corresponding bidirectional screw 32 to rotate. When the bidirectional screw 32 rotates, since the bidirectional screw 32 is welded from two rods with opposite threads, it is threadedly connected to the threaded hole of the fastening frame 31, driving the two fastening frames 31 to move towards or away from each other. The anti-slip groove 34 increases the friction to firmly clamp the sheep's limbs; then the second hydraulic rod 61 is controlled to extend and retract to adjust the height of the mounting strip 1, and then the sheep can be skinned very conveniently.
[0021] It is worth noting that the buttons corresponding to the external first hydraulic rod 21, second hydraulic rod 61 and motor 51 disclosed in the above embodiments can be freely configured according to the actual application scenario. The external control switch group controls the operation of the first hydraulic rod 21, second hydraulic rod 61 and motor 51 using methods commonly used in the prior art.
