The sorting mechanism is provided with a conveying unit 6, a recognition unit 8, a rejection unit 9 and a collecting unit 10 which are arranged at the rear part of the suction roller 5.
Based on the sorting machine, the sorting working process and the principle are as follows: the materials are discharged to the material homogenizing conveying mechanism 234 through the bin 1, and the accumulated materials are dispersed and conveyed to the material suction roller 5 through the material homogenizing conveying mechanism 234. The negative pressure mechanism connected on the material suction roller 5 adsorbs one particle of material or one particle of material in the material suction groove 51 of the material suction roller 5. Then, the rotation speed of the material suction roller 5 and the conveying speed of the conveying unit 6 are adjusted along with the forward rotation of the material suction roller 5, so that the materials in the two material suction grooves 51 at the front and rear positions on the material suction roller 5 in the rotation direction respectively fall on the two material receiving box groups 60 adjacent to each other in the front and rear directions on the conveying unit 6. The material receiving box 61 on the material receiving box group 60 corresponds to the material sucking groove 51. The materials are dispersed through the material homogenizing and conveying mechanism 234 and the material suction roller 5, an independent material is ensured to enter the material receiving box 61, and finally the independent material is identified by the identification unit 8, the image and the information of the material are extracted, the rejection unit 9 is controlled by the rejection control unit to move the material receiving box 61, and the material in the material receiving box 61 is correspondingly rejected or sorted into the material collecting box of the designated material collecting unit 10.

For example, when the betel nuts are sorted, the betel nuts can be sorted, combined and sorted according to a plurality of sorting indexes such as length, thickness and lines, and various grades of materials are obtained. Namely, the sorted materials collected in one collecting box of the collecting unit 10 are combined and sorted by a plurality of sorting indexes. The problem that the sorting machine can realize sorting according to a sorting index in the prior art by tightening the sorting machine once is solved, and the sorting machine has the advantages of high sorting efficiency, high sorting speed and good sorting precision.
