China has a long history of drinking tea and has a long history of tea cultivation, picking and processing. With the improvement of living quality, there is also a high demand for the quality of tea, and picking tea is a very important step in improving the quality of tea. In order to solve the problem of hand-picking tea time, the tea-picking machinery is difficult to enter the tea plantation due to the special planting of the tea plantation, and the shortage of rural labor force is alleviated and the economic benefits of the tea are guaranteed. In recent decades, many research and development have been carried out on the tea-producing machinery. In the 1950s, some people made reference to Japan#39;s tea-picking scissors for testing and used large scissors to pick tea. The quality was poor and could not be applied. From the late 1950s to the early 1960s, we started the research on tea-picking machines and put forward three types of models: oversized, middle-sized and small-sized. Both of them are catching up with Japan and the Soviet Union on the working principle and design. After the intermittent, delayed the time. The late seventies, on the introduction and manufacture of small and medium-sized reciprocating cutting tea-picking machine, do some related supporting work, has recently established two joint-venture tea plant and several tea plants set up by the country, machine mining The work of promoting the new look of tea production has been put on the agenda.
On the basis of consulting a large number of related documents, previous studies and relevant national design standards, the design scheme and design basis of the whole machine were confirmed. Secondly, the motion analysis of the designed tea-picking machine was carried out, Motion equation, knife speed ratio and other important parameters, and then pick tea machine vibration analysis and cutting machine steady-state response, reciprocating cutter for the existence of a large inertial force launched a series of damping measures to effectively guarantee The tea picking machine in the work of the picking effect, extending the life of the cutter.
