The driving column 34 is fixedly connected to the middle of the right side surface of the screening bucket 7. The motor 31 is arranged in the middle of the right side surface of the filtering bin 2. The cam 32 is fixedly connected to the left end of the output shaft of the motor 31. The distal end of the cam 32 is fixedly connected with a connecting shaft. The connecting rod 33 is rotatably connected between the connecting shaft and the driving column 34. The input end of the motor 31 is electrically connected to the output end of the control switch group 16. When the motor 31 runs, the output shaft of the motor 31 rotates to drive the cam 32 to rotate. The rotation of the cam 32 drives the rear end of the connecting rod 33 around the input shaft through the connecting shaft. The central axis of the output shaft rotates.
