Multi-stage sorting device for mechanically picking fresh tea leaves

Abstract

The utility model relates to a multistage sorting device for mechanically picked fresh tea leaves, which relates to the technical field of tea processing machinery. It includes fresh tea leaves winnowing parts, fresh tea leaves vibrating screening parts, feed hopper, electrical control box, and is characterized in that: tea fresh leaves vibrating screening parts include vibrating motor, vibrating sieve box, bracket assembly, said vibrating sieve box It is composed of upper and lower three-layer screens and sieve boxes arranged from coarse to fine; the air selection components for fresh tea leaves include fans and bellows components. The first group of bellows and the second group of bellows are respectively connected with two sets of air ducts; the feed hopper is connected to the first layer of coarse screen box; the second layer of medium and fine screen box is located under the first layer of coarse screen box; the third layer The fine sieve box is located below the middle and fine sieve box on the second layer, and the lower part of the third layer of fine sieve box is provided with a chamber, the left side of the chamber is provided with a debris outlet, and the right side of the chamber is provided with a fine leaf outlet. The invention has the positive effects of improving the grade quality of tea leaves and increasing the output of high-quality tea leaves.

Description

technical field [0001] The invention relates to the technical field of tea processing machinery, in particular to a multi-stage sorting device for mechanically picking fresh tea leaves. Background technique [0002] In order to improve tea picking efficiency and reduce labor costs, tea farmers have now used tea picking machines to pick fresh tea leaves. The efficiency of mechanical tea picking has been improved, but the raw materials of fresh tea leaves picked by tea picking machines are mixed with a lot of broken leaves of fresh tea leaves. They are quite similar, but the quality is very different, and it is impossible to separate the two using ordinary fresh tea leaf classifiers. Existing tea processing process, be divided into the tea tender shoots of extra-grade tea because have had a strong impact on the grade quality of tealeaves because of being mixed with too many tealeaves broken leaves. Contents of the invention [0003] The present invention provides a multi-s...

Problems solved by technology

The efficiency of mechanical tea picking has been improved, but the raw materials of fresh tea leaves picked by tea picking machines are mixed with a lot of broken leaves of fresh tea leaves. They are equivalent, but the quality is very different, and the ordinary fresh tea leaf grading machine cannot be used to separate the two

In the existing tea processing process, there are too many broken leaves in the tea buds of special grade tea, which seriously affects the grade quality of tea.
