The Working Principle Of Different Types Of Tea Pickers

A crop harvesting machine that harvests fresh and tender tea leaves from the tops of tea trees. According to different picking methods, there are two types of selective tea pickers and non-selective tea pickers. 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.

The reciprocating cutting tea picking machine is driven by a small gasoline engine of 0.6 to 14 watts or a micro motor of about 40 watts, and the power is transmitted from the flexible shaft to the hand-held picking device, which drives the cutter (there are double-action and single-action knives) and The leaf collecting device makes a reciprocating motion. The picked tea leaves are fed into a leaf collecting bag by a fan or an impeller. The picking quality is good, and the bud and leaf integrity rate can reach about 70%, which is the main type of non-selective tea picking machine development.

Hook knife cutting tea picker The cutter of the picking device is composed of two or more sets of hook knives and fixed bottom knives. Each set of hook knives makes horizontal and rotating motions to cut bud leaves. The intact rate of bud leaves can reach about 50%, but there are repeated cuttings.

Spiral roll cutting tea picking machine The picking device is a rotary knife roll equipped with two spiral blades, which is used for both cutting buds and collecting leaves. Simple structure, mostly used for manual tea plucking machine, can also be driven by power. There are severe repeated cutting phenomena, the complete rate of leaf buds is only about 30%, and the scope of application is not wide.
