Description

Technical Field

[0001] The utility model relates to the technical field of flue-cured tobacco sorting, in particular to a preliminary sorter for flue-cured tobacco. Background Art

[0002] The purpose of tobacco leaf grading is to grade the quality of tobacco leaves, give full play to agricultural resources, and achieve the goal of pricing tobacco leaves based on quality, and high quality and high price. The grading process of flue-cured tobacco leaves is to first divide them into parts, then groups, and finally grades. The first step is to distinguish the parts. The quality of tobacco leaves in different parts has obvious differences. In the national standard "Flue-cured Tobacco GB2635-92", flue-cured tobacco is divided into three parts before grading, and then divided into 42 levels based on the color of the tobacco leaves and other overall qualities. The national standard stipulates that the standard code for lower tobacco leaves is X, the standard code for middle tobacco leaves is C, and the standard code for upper tobacco leaves is B.

[0003] At present, the preliminary sorting of tobacco leaves mainly relies on photoelectric equipment to identify and sort the characteristics of various parts of the tobacco leaves, or on the collection of reflection, perspective and microscopic images of the tobacco leaves and then submitting them to a computer system for comparison, identification and sorting.

[0004] When the existing preliminary sorting equipment is in use, one or two workers are required to cooperate to place the tobacco leaves on the conveying equipment, and then the tobacco leaves are transported to the identification equipment through the conveying equipment for identification, and then transported out for sorting. Due to the manual single-piece loading, its efficiency is extremely low, which reduces the sorting efficiency of tobacco leaves. Therefore, a preliminary sorter for flue-cured tobacco is proposed.
