In view of the existing manual slaughtering of live pigs, the workload is heavy, the slaughtering effect is poor and the work efficiency is low. The following scheme is proposed, which includes a base, the top of the base is fixedly connected with a fixed column, the top of the fixed column is fixedly connected with a beam, the base is provided with an installation chamber, and the bottom inner wall of the installation chamber is fixedly connected with a motor, The output shaft of the motor is fixedly connected with a rotating shaft. The structure of the invention is reasonable and the operation is simple. The pig body is fixed by two arc-shaped splints through the motor, and then corona by the positive copper ring and negative copper ring, which effectively prevents the pig body from disorderly movement. The slaughtering knife can slaughter the pig through the electric push rod, which saves labor and improves the work efficiency The blood will flow into the collection tank and will not pollute the environment.
