[0032] Among them, the second motor 702 is started, and the second motor 702 drives the rotating shaft 703 to rotate, thereby driving the protrusion 704 to rotate. When the protrusion 704 contacts the storage frame 3, the protrusion 704 continues to rotate, which will drive the storage frame 3 to move upward. At the same time, the four telescopic rods 2 begin to stretch to prevent the storage frame 3 from deflecting.

Since the side plate 502 is threadedly connected to the screw rod 503, the other side plate 502 and the slide rod 504 cooperate to limit the rotation of the baffle 501, so the screw rod 503 can drive multiple baffles 501 to move horizontally at the same time, thereby adjusting the size of the sieve holes on the sieve plate 4. The pine nuts are screened again in the same way. This cycle is repeated, and the pine nuts are screened and graded multiple times. The operation is simple and the cost of screening and grading is effectively reduced. At the same time, one of the side plates 502 drives the indicator mark 506 to move horizontally. The moving distance of the baffle 501 is observed by the indicator mark 506 and the scale 6, so that the size of the sieve holes can be accurately adjusted.
