Background

The tobacco leaves need to have carefully selected steps before threshing, and the purpose of the tobacco leaves is to remove defective products (bad leaves) in the tobacco leaves so as to improve the usability of the tobacco leaves and refine the grade purity.

We find that most of the places at present still adopt traditional stall-type leaf selection or strip-table leaf selection by researching a plurality of domestic redrying processing enterprises and looking up foreign similar characters, audio-visual video data and the like, and the degree of automation is low. The leaf selection mode has the following defects: 1. the leaf selecting personnel are in a semi-squatting state for a long time, the operation space is small, fatigue is easy to cause, and the efficiency is low; insufficient light causes poor visual effect; 2. the secondary pollution to tobacco leaves is easily caused by poor ground leaf selection environment; the broken leaves and the broken powder are difficult to clean; 3. the field environment of the stall type leaf selecting field is complex, which is not beneficial to logistics transportation and quality inspection of the tobacco leaves to be sorted; the mixed operation of people and vehicles brings about great potential safety hazard, so we propose a tobacco leaf selecting and discharging platform to solve the problems.
