The top of the fixed block 28 is fixedly connected to the filter frame 29, the bottom end of the filter frame 29 is inclined, and the screen 30 is fixedly connected to the bottom end of the filter frame 29. The filter frame 29 is fixedly connected to the discharge pipe 31 on the side close to the collection box 32, and a slide groove compatible with the discharge pipe 31 is provided on the side wall of the screening machine component 7 close to the collection box 32.
