Tea plucking machine

Abstract

The invention discloses a tea plucking machine which can lift, stretch, retract and rotate in a small space. The tea plucking machine comprises a rack assembly. Caterpillar band assemblies are installed on the two sides of the rack assembly. The upper portion of the rack assembly is provided with a gasoline tank, a power mechanism, a rotating and lifting mechanism and a tea leaf collecting box. The rotating and lifting mechanism is provided with a rotating and lifting platform. The upper portion of the rotating and lifting platform is provided with a tea plucking mechanical arm. The tea plucking machine is characterized in that the tea plucking mechanical arm comprises a first vertical installation plate, a vertical rotating air cylinder is arranged on the first vertical installation plate, a rotating shaft of the rotating air cylinder stretches out of the rotating air cylinder and is horizontally arranged, the rotating shaft is fixedly provided with a U-shaped connecting seat, a second vertical installation plate is fixed to the side face of the U-shaped connecting seat, a vertical telescopic air cylinder is arranged on the second vertical installation plate, a horizontal clamping seat is fixed to the end of the vertical telescopic rod of the vertical telescopic air cylinder, a horizontal telescopic air cylinder is installed on the clamping seat, a vertical connecting disc is fixed to the end of a horizontal telescopic rod of the horizontal telescopic air cylinder, and a plucking jaw is installed on the connecting disc.

Description

technical field [0001] The invention relates to tea picking technology, in particular to a tea picking machine. 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 part of...

AI Technical Summary

Problems solved by technology

[0004] The manipulators of the above-mentioned tea picking machines often have the following problems: 1. The picked tea leaves are directly sent into the tea collection box through the manipulator. The lifting and rotating platform places the picking manipulator in different picking positions to pick tea leaves. Since the tea picking machine itself does not have the functions of lifting, telescopic and rotating in a small space, the range of motion of each lifting and rotating platform is different. Larger, therefore, it is easy to miss the tea leaves and reduce the output of tea picking; 3. The tea leaves are only cut off by the blades at the end of the tea picking jaws of the tea picking manipulator. The cutting force is limited, and the tea leaves and the tea handle are often not completely cut off, but The picking is done by pulling the tea leaves and tea handles off with the picking claws. During the pulling process, the tea leaves are easily damaged, which will affect the later processing.
