Abstract: The reduction in scope and time of the sheep’s activity will cause the wear degree of sheep’s hooves to be lower than the growth rate, which will lead to hoof diseases such as sheep hooves tip up, hoof wall split and limb deformation, and affect sheep’s walking and food intake.In order to solve the above problems, a sheep hooves pruning device was designed, which consisted of three parts: clamping mechanism, overturning mechanism and cutting mechanism. The device could restrict the movement of sheep body, realize the turning of sheep body and cut hooves. The simulation analysis of the turning mechanism were carried out by using ANSYS to verify the strength and stiffness.The prototype was manufactured and tested.The results showed that a hooves pruning device was successfully designed, with maximum stress of 28.128 N/m~2 and maximum displacement of 0.661 6 mm after load-bearing. The device was easy to operate and move, and can independently cut sheep hooves by a single person.It indicated that this device could improve the efficiency of hoof nail pruning, and reduce labor intensity and was suitable for large-scale breeding.
