Method and device for picking high-quality tea leaves

Abstract

The invention discloses a method and a device for picking high-quality tea leaves. The method comprises the following steps: firstly, introducing tea leaves into a sorting tooth groove by using a sorting tooth, and then, cutting off the tea leaves by using a horizontal rotating movable cutter and a fixed blade, wherein the design of fixedly connecting a tea shifting body and a movable blade is used for realizing the purposes of shearing, shifting and combining in the cutting process of the tea leaves, thus the cut tea leaves can be shifted into a collecting device of the tea leaves to realize the purpose of picking the tea leaves. The invention adopts the mode of combining a horizontal rotating cutting blade and a fixed surface cutting blade to enable the cutting mode of the tea leaves to be similar to the shearing mode, and because the cutting direction and pushing direction are identical, the damage surfaces caused by cutting the tea leaves are reduced; the cut tea leaves are shifted into a tea inlet in the shearing, shifting and combining mode, thereby effectively improving the picking efficiency and avoiding the loss caused by the falling of the tea leaves in the picking process; and meanwhile, the sorting tooth is used for introducing the tea leaves for cutting, thereby greatly reducing the probability of picking old stems and old leaves of the tea leaves and improving the picking quality of the tea leaves.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a method and device for picking green tea. Background technique [0002] At present, picking tea leaves (green) is a labor-intensive labor in tea production, which generally accounts for more than 50% of the labor in tea garden management. Picking tealeaves (green) by hand is time-consuming and laborious. Often because of the slow aging of high-quality tea greens caused by manual picking, it cannot be picked in time, which seriously affects the income of high-quality tea leaves. The world's major tea-producing countries are constantly researching, finding and improving efficient methods to replace manual picking. Tea (green) picking machines are divided into two types: selective tea picking machines and non-selective tea picking machines according to different picking methods; It is motorized, electric and manual; according to the operation form, it can be divide...

AI Technical Summary

Problems solved by technology

At present, the research and application of tea picking machinery in the world are mainly focused on the picking of tea leaves for the general public. The widely used picking machine is a reciprocating cutting double or single picking machine. Although this type of picking machine can greatly improve the picking efficiency and save a lot of labor, shorten the picking cycle, and ensure the quality of fresh leaves, etc., but there are also disadvantages such as high tea breakage rate, large damage surface, more old stalks and old leaves in the green tea, and high labor intensity, so it is only suitable for medium and low-grade tea. pick

At present, there is no mechanized picking technology and equipment suitable for picking high-quality green tea with high requirements.
