[0057] The specific usage mode and functions of this embodiment:

[0058] When the present invention is in use, first connect the intelligent control box 200 to an external power supply, and then connect an external collection device to the right end of the conveying unit 100 to ensure that qualified tobacco leaves and unqualified tobacco leaves can be collected separately. Extend the output shaft of a row of linear electric cylinders 401 through the intelligent control box 200 so that the top of the cleaning rag 403 contacts the conveying belt 104. When the conveying belt 104 rotates, the cleaning rag 403 automatically removes the sundries on the conveying belt 104. The removed sundries can automatically move into the inclined conveying frame 102 through the inclined guiding frame 404, so that the sundries on the conveying belt 104 can be discharged simultaneously with the unqualified tobacco leaves. The cleaning rag 403 can always be in elastic contact with the conveying belt 104, improving the cleaning effect of the conveying belt 104. When the output shaft of the row of linear electric cylinders 401 contracts, the cleaning rag 403 can be separated from the conveying belt 104, facilitating the staff to replace the new cleaning rag 403. The sorting staff stand on the corresponding force-bearing plate 304 so that the staff on the front and back sides correspond. When the staff is at the working position, that is, above the force-bearing plate 304, the force-bearing plate 304 can move downward after being stressed. When the staff leaves the working position, that is, leaves the force-bearing plate 304, the force-bearing plate 304 can slide upward under the elastic force of the two support springs A305. When the staff is at the working position, the detection button 307 is in the pressed state. When the staff leaves the working position, the detection button 307 is in the unpressed state. The intelligent control box 200 can automatically adjust the working time of the servo motor 105 according to the number of presses of the detection button 307, realizing the intermittent operation of the servo motor 105, so that the tobacco leaves after sorting can be quickly conveyed. At the same time, it is ensured that when the tobacco leaves are sorted, the conveying belt 104 is in a stopped working state, which is more conducive to the staff to pick up the unqualified tobacco leaves. When the servo motor 105 works, the conveying belt 104 can drive the tobacco leaves to move, realizing the automatic movement of the tobacco leaves, which is beneficial to improving the sorting efficiency of the tobacco leaves. Place the unqualified tobacco leaves in the inclined conveying frame 102 to realize the automatic conveying of the unqualified tobacco leaves after sorting.
