Tea winnowing machine

Abstract

The invention discloses a tea winnowing machine. The tea winnowing machine comprises a winnowing tank and a fan, wherein the winnowing tank is a transversely horizontally placed cuboid tank; supporting feet are mounted at the bottom of the winnowing tank; an air inlet is formed in the upper part of a right plate of the winnowing tank; a feed hopper is mounted on a feed inlet in the right side of a top plate of the winnowing tank; a plurality of continuous longitudinal material collecting hoppers are arranged on a bottom plate of the winnowing tank; hopper openings of the material collecting hoppers are rectangular; the fan is an induced draught fan; the fan is mounted and fixed to an air draft opening in a left plate of the winnowing tank; a longitudinal slot is formed between every two adjacent material collecting hoppers; rubber layers are arranged on the side walls in the slots; the length of the slots is the same as the length of the material collecting hoppers; baffle plates are inserted from the slots into the winnowing tank from bottom to up; the rubber layers clamp the baffle plates; and the baffle plates can be pulled up and down between the rubber layers. According to the tea winnowing machine, the structure is simple, the operation is convenient, the manufacturing cost is low, the winnowing effect of the tea winnowing machine can be remarkably improved, and the quality of tea of all winnowing levels is effectively improved.

Description

technical field [0001] The invention relates to tea production equipment, in particular to a tea winnowing machine. Background technique [0002] In the process of tea production, it is necessary to classify the quality of tea leaves. Generally, it is divided according to the degree of whole and broken leaves of the same kind of tea leaves. Since the quality of the whole leaf is the largest and the quality of tea leaves is the smallest, in this process, wind is usually used. The sorting machine is used for sorting, and the tea leaves of different qualities are screened by wind power. [0003] At present, the most common winnowing machine usually consists of a winnowing box, a feeding device, a blower, and a discharge port. , use the wind force of the blower to air-select the tea leaves, the whole tea leaves fall first, and the broken tea leaves are blown to the end of the air-selection box by the wind to fall, and the rest of the tea leaves fall in turn according to the siz...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a tea winnowing machine, which uses an induced draft fan instead of a blower, overcomes the problem of large wind power loss, and effectively improves the winnowing effect of the tea winnowing machine
