[0003] A search revealed a Chinese patent (CN211814653U) that discloses a rust removal device for recycling waste motors. This patent places the waste motors into the inner cavity of a rust removal box through a feeding pipe, and then adds pickling solution to the inner cavity of the rust removal box. The rotation of the turntable eventually causes the rust removal box to move left and right, so that the pickling solution can fully contact the surface of the waste motors. However, the waste motors inevitably bump into each other during the left and right movement, which affects the subsequent recycling. Therefore, we propose a rust removal device for recycling waste motors. Utility Model Content
