Pour the grains to be filtered onto the second filter plate 6, set the driving motor 11, the output end of the driving motor 11 drives the first reciprocating lead screw 14 to rotate. The rotation of the first reciprocating lead screw 14 makes the first sliding block 13 reciprocate along the first positioning block 10 and the first reciprocating lead screw 14 under the limitation of the first positioning block 10. The first sliding block 13 drives the first scraping plate 15 to reciprocate along the second chute 8. The reciprocating movement of the first scraping plate 15 reciprocally pushes the grains on the second filter plate 6, so that the grains meeting the size pass through the large filtering holes 9 and fall onto the first filter plate 2.

The rotation of the first reciprocating lead screw 14 makes the first sliding block 13 reciprocate along the first positioning block 10 and the first reciprocating lead screw 14 under the limitation of the first positioning block 10. The first sliding block 13 drives the first scraper 15 to reciprocate along the second sliding groove 8. The reciprocating movement of the first scraper 15 further pushes the grains on the second filter plate 6 reciprocally, enabling the grains that meet the size requirements to pass through the large filtering holes 9 and fall onto the first filter plate 2. The rotation of the first reciprocating lead screw 14 drives the first gear 16 to rotate. The first gear 16 drives the second gear 17 to rotate. The rotation of the second gear 17 makes the second reciprocating lead screw 21 rotate. The rotation of the second reciprocating lead screw 21 makes the second sliding block 20 reciprocate along the fourth sliding groove 19 and the second reciprocating lead screw 21 under the limitation of the second positioning block 18.

The reciprocating movement of the second scraper 22 further pushes the grains on the first filter plate 2 reciprocally, enabling the grains that meet the size requirements to pass through the small filtering holes 5. Thus, the filtering and screening device for grain processing can perform two-stage filtering, effectively improving the accuracy of filtering by the filtering and screening device for grain processing and making the filtering effect of the filtering and screening device for grain processing better. The grains passing through the small filtering holes 5 fall into the drawer 25. When the grains in the drawer 25 are full, the handle 26 is pulled.
