Blade adjusting mechanism of tea picking machine

Abstract

The invention discloses a blade adjusting mechanism of a tea picking machine. The blade adjusting mechanism comprises a shell which comprises a baseplate, a plurality of cutting blades are arranged on the front side of the baseplate, each cutting blade comprises a left blade and a right blade which are fixed on a first driving shaft and a second fixing shaft respectively, a limiting plate is arranged on the side face of each first driving shaft, a groove is formed in the side face of each second driving shaft, each limiting plate is inserted into the corresponding groove, and a plurality of through holes are formed in the top face of each second fixing shaft and all positioned exactly above the corresponding groove; an iron chain is tied on the upper surface of the baseplate, the other end of the iron chain is connected with a limiting rod, a gap is arranged in each of left and right side faces of the shell, a threaded hole is formed in each of left and right end faces of the baseplate, an internal thread is arranged on the inner surface of each threaded hole, a bolt is arranged on the lateral side of each threaded hole and penetrates the corresponding gap to be connected with the corresponding threaded hole, and a cross rod is arranged at the head of each bolt. The blade adjusting mechanism can realize free adjusting of blade height, can change moving range of the blades according to density of tea leaves and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of tea picking machines, in particular to a blade adjustment mechanism of a tea picking machine. Background technique [0002] The tea picking machine is a crop harvesting machine that harvests the young and tender tea leaves from the top of the tea tree. According to different picking methods, there are two types of selective tea picking machines and non-selective tea picking machines. Selective tea picking machines have types such as breaking type and friction type. The former uses the principle of bending and breaking to pick fresh and tender tea leaves while retaining thick and old branches; the latter uses a pair of elastic fingers to clamp the tea leaves, relying on the static friction between the fingers and tea leaves to pick off new leaves while retaining old leaves and young leaves. bud. Due to the difference in the environment of the tea tree, the blade of the tea picking machine should be adju...

AI Technical Summary

Problems solved by technology

[0003] But such blade adjusting mechanism has the following problems, the one, because the growing way of tea tree is different, in order to be able to pluck new leaf and keep old leaf, the height of blade must be adjusted all the time, very troublesome with set screw, and can not change blade at arbitrary height, affects Work efficiency; the second is that the cutting blades of the tea picking machine are usually cut in groups. When the tea leaves are dense, the distance between adjacent cutting blades will cause more tea picking omissions. When the tea leaves are loose, in order to improve efficiency, The distance between the cutting blades is better, but the existing technology cannot solve these problems well, so a blade adjustment mechanism of the tea picking machine is designed
