When the convex block 16 rotates to the bottom of the filter plate 12, it will squeeze and push the filter plate 12 to vibrate, thereby realizing the screening of the walnuts. The small-sized walnuts will fall below the filter plate 12. At this time, starting the transmission motor 18 will cause the transmission shaft 19 to drive the rectangular block 20 to rotate, releasing the sealing effect on the screening box 3, thus achieving the purpose of collecting small-sized walnuts.

[0047] When the large-sized walnuts are above the filter plate 12, starting the lifting motor 21 at this time will cause the connecting shaft 22 to drive the rotating rod 23 to rotate, and then cause the movable rod 24 to rotate, pulling the vertical block 25 and the baffle 26 to move upward, thereby releasing the sealing effect on the screening box 3. At this time, the large-sized walnuts will fall into the collection box 28 through the chute 27.
