[0030] The screening mechanism comprises a feeding hopper 51, an inner conical cylinder 52, a coarse grating 53, an outer conical cylinder 54 and a fine grating 55, the feeding hopper 51 is fixedly installed on the connecting frame 4, the inner conical cylinder 52 is rotatably installed at one end of the feeding hopper 51, the feeding hopper 51 is communicated with the inner conical cylinder 52, four coarse gratings 53 are embeddedly installed around the inner conical cylinder 52, the outer conical cylinder 54 is rotatably installed at one end of the inner conical cylinder 52, and eight fine gratings 55 are embeddedly installed around the outer conical cylinder 54.

[0031] The driving mechanism comprises a vertical plate 61, a motor 62, a rotating shaft 63, a cylindrical gear 64, an inner ring gear 65 and an outer ring gear 66, the vertical plate 61 is installed on the other side of the support 3 through bolts, the motor 62 is installed on the vertical plate 61 through bolts, the rotating shaft 63 is installed on the output shaft of the motor 62 through a key, the cylindrical gear 64 is installed at the other end of the rotating shaft 63 in a key connection manner, the inner ring gear 65 is installed on one side of the outer conical cylinder 54, the outer ring gear 66 is installed on one side of the inner conical cylinder 52, the cylindrical gear 64 is located between the inner ring gear 65 and the outer ring gear 66, and the cylindrical gear 64 is meshed with the inner ring gear 65 and the outer ring gear 66.

[0032] ​When using this device to sort agricultural products, the operator first starts the motor 62 to rotate. The motor 62 drives the rotating shaft 63 to rotate, which in turn drives the spur gear 64 to rotate. The spur gear 64 then drives the inner gear ring 65 and the outer gear ring 66 to rotate. The inner gear ring 65 then drives the outer cone cylinder 54 and the fine screen 55 to rotate, while the outer gear ring 66 drives the inner cone cylinder 52 and the coarse screen 53 to rotate. The operator pours an appropriate amount of agricultural products into the feed hopper 51. The agricultural products first flow into the inner cone cylinder 52 and undergo preliminary sorting through the coarse screen 53. Agricultural products that do not pass through the coarse screen 53 are discharged along the inner cone cylinder 52. Agricultural products that pass through the coarse screen 53 are discharged. The products fall into the outer cone 54 and undergo secondary sorting through the fine screen 55. Products that do not pass through the fine screen 55 are discharged along the outer cone 54, while those that pass through the fine screen 55 fall into the bottom frame 2. After the products are sorted, the operator turns off the motor 62, which drives the spur gear 64 to rotate. The rotation of the spur gear 64 drives the inner gear ring 65 and the outer gear ring 66 to rotate, thereby driving the inner cone 52 and the outer cone 54 to rotate. After the products are discharged into the inner cone 52, they undergo preliminary sorting through the coarse screen 53, and secondary sorting through the fine screen 55, which improves the efficiency of product sorting.

With the continuous contact of the agricultural products with the blocking mesh plate 10, the blocking mesh plate 10 will swing continuously, and the agricultural products will be more concentrated in the innermost end of the inner cone cylinder 52, so as to improve the contact time of the agricultural products with the coarse mesh sieve 53 during sorting, and further improve the efficiency of agricultural product sorting.
