Novel litchi picker

Abstract

A novel litchi picker is mainly composed of a shearing mechanism, a guiding mechanism and a control handle; the shearing mechanism is composed of a fixed blade, a moving blade, a pull rod and a handle; the moving blade has a convex cutting edge and at the same time, the fixed blade is grinded into 40 DEG to 50 DEG slant angle at the position fruit stems are pulled so that a certain cut-in angle isguaranteed when fruit stems are cut to reduce shearing force; a front end of the guiding mechanism is a stir rod and the bottom is stitched with a fruit receiving canvas; under the effect of the spring force before picking, the guiding mechanism is in a tensioned state; the stir rod is close to a main rod; the tightened picker can conveniently extend to litchi trees; after positioning, a push cylinder is pushed to unfold the stir rod to push branches and leaves aside, which is convenient for picking; the control handle is positioned at the rear of the picker, which is convenient for manual operation. The invention has simple structure, high work efficiency, low cost and convenient installation, and satisfies the requirements for string fruit picking of litchi, and has important significance for improving the level of agricultural machinery in China.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a novel litchi picker. Background technique [0002] Litchi is a good fruit produced in southern my country, and its cultivation area and output both rank first in the world. At present, lychees are harvested manually, which is labor-intensive, inefficient and expensive. In order to improve the efficiency of fruit and vegetable picking, a lot of research has been done on the robotic picking of tomatoes, cucumbers, strawberries, apples, citrus, mushrooms, eggplants and litchis at home and abroad. Although great progress has been made, some fruit and vegetable picking robots have also A prototype has been produced, but it is still a long way from practicality and commercialization. The main reason is that the fruit recognition rate and picking rate are not high, the damage rate is high, and the manufacturing cost is high. Therefore, after continuous optimization, a...
