A tea picking method for automatically sorting tea leaves

Abstract

The invention provides a tea picking method for automatically sorting tea leaves. The method adopts a circular tea picking machine to pick tea. The circular tea picking machine includes a collector (1), a driving chain plate (2), a supporting chain plate (3), tea picking mechanism housing (4), breaking mechanism (5), guide baffle (6), breaking sawtooth (7), operating handle (8), material collecting port and chain; wherein, the breaking mechanism (5) Including driving bracket (51), fixing bracket (52), breaking piece (54), adjusting bracket (53) and fastening screw (55). This method realizes cyclic tea picking, avoids the impact effect between equipment parts during reciprocating motion, and makes the broken end faces even, which greatly improves the efficiency of tea picking, improves the quality of picked tea leaves and tea trees, and effectively avoids the damage of picked tea leaves. And the quality of the tea tree is damaged; at the same time, the method can be used to pick tea leaves of different varieties and different levels of old and new, and the picking has a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of tea picking, in particular to a tea picking method for automatically sorting tea leaves. Background technique [0002] China is the hometown of tea. Our country has a history of more than ten thousand years of discovering and utilizing tea trees, and it is the birthplace of human beings drinking tea, growing tea, and making tea. [0003] Tea is usually produced in large quantities in spring and autumn, and the picking is highly seasonal and seasonal, especially for spring tea. If the fresh leaves cannot be picked in time, it will have a great impact on the quality of the finished tea. At present, the main tea leaves are There are two kinds of tea picking methods, one is to rely on manual picking, and the other is to use tea picking equipment. [0004] Manual picking is usually manual picking root by root. Although this method has high picking accuracy, it can achieve reliable graded picking, effectively...

Problems solved by technology

[0004] Manual picking is usually manual picking root by root. Although this method has high picking accuracy, it can achieve reliable graded picking, effectively distinguish old leaves from young shoots, and ensure good picking quality, but the efficiency of manual tea picking is low. A large number of human resources are used to operate, the labor cost is high, and manual picking is easy to prolong the picking cycle of tea leaves, resulting in missing the best harvesting period of tea leaves

[0005] The most commonly used tea-picking equipment is usually shearing-type tea-picking equipment, which has high working efficiency and fast tea-picking speed; however, shearing-type tea-picking equipment cannot effectively distinguish young shoots from old leaves, and it is very easy to distinguish young shoots from old leaves when picking. The leaves are cut together, which seriously reduces the quality of the tea; the picking method of the shearing tea picking equipment is completely fixed, and cannot adapt to the state of tea of ​​different varieties and different degrees of age.

At the same time, the existing tea picking equipment uses a blade assembly to cut off the tea leaves, so as to realize the picking of the tea leaves. The blade assembly is usually composed of two or more blades, and the relative movement of the multiple blades realizes the shearing action of the tea leaves. As time increases, multiple relative reciprocating impacts of multiple blades will cause the blades to become blunt and loosen, eventually resulting in gaps between the blades of multiple blades during shearing or burrs on the fracture surface of the tea leaves after shearing, or even Fragmentation occurs; while the fracture surface of the tea leaves is burr-shaped or cracked, the exposed area of ​​the tea fracture will increase, and the damaged tissue will increase, resulting in an increase in the amount of slurry precipitation, and it is difficult to quickly dry and seal the fracture. The fracture cannot be dried quickly and is oxidized by the air, which causes the tea to appear brownish red (oxidized) when it is in contact with boiling water, which affects the quality of tea picking and the taste of drinking; It is not conducive to the growth of tea trees after picking, and increases the cost of subsequent maintenance and planting

[0006] In addition, the existing picking methods are immature, imperfect, and unsystematic, resulting in varying quality of tea leaves after picking, resulting in reduced production of tea gardens, reduced tea quality, and poor taste, which directly contribute to tea planting and production. , processing has brought many negative effects
