The rotating shaft 17 is rotatably connected to the lifting seat 62. The first electric push rod 61 is electrically connected to the PLC controller 2. Stick the garbage bag at the bottom of the turntable 9 corresponding to the bracket 13, so that the skin peeled off the sweet potato can enter the garbage bag through the bracket 13. Place the sweet potato on the bracket 13, and the output shaft of the servo motor 7 drives the turntable 9 to rotate, so as to move the bracket 13 to the position corresponding to the needle 18. Then, the telescopic end of the first electric push rod 61 drives the lifting seat 62 to perform a lifting motion, so that the needle 18 is inserted into the sweet potato.
