Tea picking machine is a crop harvesting machine that collects fresh and tender tea leaves from the top of tea trees. It is a special operating machine for tea garden management. In the past, tea tree pruning was mostly manual harvesting, which took time and effort. For mechanized tea gardens, to achieve mechanized tea harvesting, a tea harvester is an indispensable condition. The tea picker is a mechanical method instead of the traditional manual picking, which can pick about 50 times the amount of artificial tea at the same time. Therefore, the popularity of the tea picker not only has an important help to realize the mechanization of the agricultural industry in China, but also implements mechanized tea picking. Can improve work efficiency, increase efficiency, save a large number of labor, ease the picking of flood peaks, shorten the picking cycle, and ensure fresh leaf quality. Since 2000, in order to overcome the shortcomings of petrol tea harvesters that produce oil and gas “run, run, drip, leak” and easily pollute the tea garden environment, various types of electric tea harvesters have emerged at the historic moment in order to ensure the original ecology of tea quality. , Played a good role in promoting.

First, the classification of tea pickers

1) According to the number of operators: it can be divided into two types: single tea picker and double tea picker;

2) According to power and energy: it can be divided into three types: fuel-type motorized tea-picking machine, battery electric tea-picking machine and hand-cranked soft-shaft drive tea-picking machine;

3) According to the structure and function: it can be divided into two types: tea machine with blower and tea machine without blower;

4) Divided by walking mode: it can be divided into four types: portable tea picker, stretcher tea picker, walk-in tea picker and self-propelled tea picker;

5) Divided by cutting knife type: it can be divided into three types: reciprocating cutting tea picking machine, spiral hob tea picking machine and horizontal rotary hook knife tea picking machine;

6) According to the picking method: it can be divided into two types: selective tea picker and non-selective tea picker.

There are types of selective tea picking machines, such as break type and friction type. The former uses the principle of bending and breaking to pick fresh and tender tea leaves while retaining thick old branches; the latter uses a pair of elastic pick fingers to hold the tea leaves and rely on the static friction between the pick fingers and the tea leaves to pick off new leaves while retaining the old leaves and young ones. bud. Due to low production efficiency and high requirements for the operating conditions of tea gardens, selective tea harvesters have not been widely promoted. Non-selective tea plucking machine is also called shearing tea plucking machine, which uses the shearing principle to pick tea leaves. Because of its simple structure and convenient use, it has been popularized.
