One side of the second reciprocating screw 25 is threadedly connected with the movable frame 9. The lower end of the movable frame 9 is hinged with a first sieve plate 10. The position of the first sieve plate 10 is at the upper end of the feed hopper 5. One side of the first sieve plate 10 is fixedly connected with a connecting spring 27 , one end of the connecting spring 27 is fixedly connected to the movable frame 9, the outer side of the first sieve plate 10 is connected to the movable frame 9, the inner side of the first sieve plate 10 is connected to the connecting spring 27, a collecting plate 11 is provided at the upper end of the feed hopper 5, and the collecting plate 11 is inserted on one side of the fixed rod 16. The size of the collecting plate 11 is larger than the size of the upper end of the feed hopper 5. One side of the collecting plate 11 contacts the support frame 6, a movable groove 7 is provided on one side of the movable frame 9, and a limiting rod 8 is slidably connected to one side of the movable groove 7, and a limiting groove 28 is provided on one side of the first sieve plate 10. A limiting groove 28 is slidably connected on one side, and the limiting rod 8 is closely fitted with the limiting groove 28. By setting the movable frame 9 and the first sieve plate 10, the dust on the outer surface of the agricultural product is shaken off. By setting the second output motor 26, the second reciprocating screw 25, and the second slide groove 18, the movable frame 9 drives the agricultural product to move, so as to facilitate the shaking off of the dust. By setting the collecting plate 11 and the fixing rod 16, the shaken dust is collected and discharged. By setting the connecting spring 27, the limiting groove 28, the limiting rod 8, and the movable groove 7, the first sieve plate 10 is fixed.

[0027] When in use, agricultural products are used for quality inspection without a large amount of screening. The prepared agricultural products are poured into the movable frame 9, so that the agricultural products fall onto the first sieve plate 10, and then the second output motor 26 is started by the control structure to drive the second reciprocating screw 25 to rotate, thereby driving the movable frame 9 to reciprocate in the second slide 18, shaking the agricultural products, so that the dust on the agricultural products is shaken off, and then leaks out through the first sieve plate 10, so that the dust falls onto the collecting plate 11. After the dust is shaken off, the movable frame 9 returns to the middle position, and the second output is stopped. The motor 26 is pulled out, and the fixing rod 16 is pulled out, so that the collecting plate 11 can be separated from the supporting frame 6, and the dust can be cleaned. Then the limiting rod 8 is moved to make it move in the movable groove 7 and disengage from the limiting groove 28. The first sieve plate 10 is pressed down by the weight of the agricultural products, so that the first sieve plate 10 moves in a downward circle to discharge the agricultural products into the feed hopper 5. After the agricultural products enter, the first sieve plate 10 loses pressure and is pulled back by the connecting spring 27. Then the limiting rod 8 is pushed back into the limiting groove 28 to fix the first sieve plate 10, so as to achieve the purpose of cleaning the dust on the surface of the agricultural products.
