Mechanical hand for harvesting tea

Abstract

The invention discloses a mechanical hand for harvesting tea that is capable of being lifted, stretched and rotated in a small space, wherein the mechanical hand comprises a first vertical mounting plate; the first vertical mounting plate is provided with a vertical rotary cylinder; a rotary shaft of the rotary air cylinder stretches out of the rotary air cylinder and the rotary shaft is set horizontally; a U-shaped connecting base is fixed on the rotary shaft; a second vertical mounting plate is fixed on a side face of the U-shaped connecting base; the second vertical mounting plate is provided with a vertical telescopic air cylinder; a horizontal clamp holder is fixed on an end portion of a vertical telescopic rod of the vertical telescopic air cylinder; a horizontal telescopic air cylinder is mounted on the clamp holder; a vertical connecting disc is fixed on an end portion of a horizontal telescopic rod of the horizontal telescopic air cylinder; and a harvesting clamp claw is mounted on the connecting disc.

Description

technical field [0001] The invention relates to tea picking technology, in particular to a tea picking manipulator. Background technique [0002] Tea picking is not only related to the quality of tea raw materials, but also affects the growth and development of tea trees. Reasonable tea picking can promote the increase of tea production to a certain extent, and has the effect of preventing diseases and insect pests. Tea picking is highly seasonal, especially spring tea, if the fresh leaves are not picked in time, the quality of the finished tea will be affected. The traditional method is to pick by hand. Generally, each person works for about eight hours a day, and can only pick about 2Kg of tea at most. The labor intensity is high and the work efficiency is low. [0003] In order to reduce the labor intensity of tea picking and improve tea picking efficiency, tea picking machines are usually used for tea picking at present. The tea-picking manipulator is an important par...

AI Technical Summary

Problems solved by technology

The above-mentioned tea-picking manipulator often has the following problems: 1. Usually, the picking manipulator is placed in different picking positions by lifting and rotating platforms to pick tea leaves. The function of each lifting and rotating platform is large, so it is easy to miss tea leaves and reduce the output of tea picking; 2. Only the blade at the end of the picking jaw of the tea picking manipulator cuts off the tea leaves, and the cutting force is limited , often the tea leaves and the tea handle are not completely cut off, but the picking is completed by pulling the tea leaves and the tea handle off with the picking claws. During the pulling process, it is easy to make the tea leaves incomplete and affect the later processing; 3. The picked tea leaves are It is very inconvenient to operate the tea picking manipulator if it is directly sent into the tea collection box by the manipulator, and the movement is slow, and the efficiency of tea collection is low
