Both the punched frame body 201 and the conical frame 301 are arranged in a conical structure. The conical frame 301 is a structure without holes. The undersize of the punched frame body 201 will move upward along the conical frame 301 under the action of centrifugal force. A screen 202 is attached to the inner surface of the punched frame body 201. The screen is used to filter materials of different thicknesses. The lower end of the conical frame 301 is connected with a hollow shaft 307 by bolts. A rotating shaft 204 is arranged in the hollow shaft 307. There is a bearing between the rotating shaft 204 and the hollow shaft 307 for rotatably supporting the rotating shaft 204. This structure is a conventional technology and will not be described in detail here. The upper end of the rotating shaft 204 is fixedly connected with the lower end of the punched frame body 201. A small pulley 205 is arranged at the lower end of the rotating shaft 204. A large pulley 308 is arranged at the lower end of the hollow shaft 307.
