An eccentric wheel 13 is fixedly installed on the output shaft of the servo motor 12, and an annular groove 19 is symmetrically opened on the top and bottom of the eccentric wheel 13. The eccentric wheel 13 is arranged on the screening On one side of the box 8, a limiting groove is provided at one end of the convex plate, and sliding rods 18 are symmetrically arranged at the top and bottom of the inner side of the limiting groove. One end of the eccentric wheel 13 is movably arranged inside the limiting groove, and the sliding rod 18 is slidably installed inside the annular groove 19.
