The front wall of the sand silo 6 is provided with a sieve plate 9 with a transverse strip-shaped hole at the upper end.

The filter screen 8 is arranged at the lower part of the screening bin 2, and the edge of the filter screen 8 is embedded in the slide way 18 and can slide along the slide way 18. The front end of the filter screen 8 is hinged with the upper arm of the C-shaped filter knife 7. The front end of the filter cutter 7 is elastically hinged with a middle beam of the machine base 1, and a lower arm of the C-shaped filter cutter 7 penetrates through a strip-shaped hole on a screen plate 9 on the front wall of the sand bin 6. The tail ends of the upper arm and the lower arm of the filter cutter 7 are connected through a connecting buckle, and the connecting buckle is fixedly connected with a spring in the direction towards the sieve plate 9. The upper arm of the filter cutter 7 is provided with a slope corresponding to the ratchet of the reamer 4, and the filter cutter 7 is pushed to move forwards along the slide way 18 by extruding materials to the filter cutter 7 through the rotation of the reamer 4. When the material is discharged or screened, the filter knife 7 is reset under the action of the spring. Due to the fact that the filter knife 7 reciprocates to drive the filter screen 8 to reciprocate, screening effect on black sand in wood shavings and auxiliary wood shavings entering the tearing bin 11 are achieved. Similarly, the filter knife 7 and the filter screen 8 adopt a modular design, so that the filter knife is convenient to disassemble.
