Description

Broken formula tea-leaf picker of function is selected separately in area

Technical Field

The invention relates to the field of tea pluckers, in particular to a breaking type tea plucker with a sorting function.

Background

As is well known, tea leaves are already an essential part in the life of people no matter 'wood rice oil salt sauce vinegar tea' or 'piano chess calligraphy and painting poetry wine tea', especially China is a country of origin of tea leaves, the tea production history is long, and people not only form a habit of drinking tea, but also influence the whole world.

The tea is also a country with highest requirement on the quality of fresh leaves in the world, people need to drink tea, identify varieties, see tea soup, smell tea fragrance, taste and see the bottom of the leaves … …, and the tea is divided into six categories according to the manufacturing process, namely: green, red, white, yellow, cyan, black. The ratio of green tea to black tea is about 80%. Therefore, 80% of tea leaves in China usually have extremely high requirements on the quality of fresh leaves (raw materials) before being made. Such as: … … reciprocating tea pluckers are available on the market for the time being, the bud leaves are complete (too many broken leaves are not good enough), the specification is uniform (the lengths are not good enough), and the tea pluckers cannot have variegated colors (old leaves and fresh leaves are not good enough to be damaged), but because all the fresh leaves entering the shearing range are completely sheared, the fresh leaves of the tea plucked by the reciprocating tea pluckers are mixed raw materials comprising new tips, old leaves, tea stalks (old branches) and the like which can be used for making tea, and if the raw materials are further added into yellow tea and white tea, about 90% of the tea leaves are not suitable for use.

Since the current tea plucking machine technology cannot solve the 90% of problems, tea plucking can only be carried out manually.

With the serious aging and the fact that young people are not willing to stay in rural areas, we know that spring is the time when the tea is the best in price, and the tea picking period is very short. Tea growers can only ask a large number of outside workers to help picking at the moment, and half of the annual harvest is paid to the pickers. In summer and autumn, the applicant can not cost any more because of the price reduction of the tea, and a large amount of tea can not be picked, and only the picking can be abandoned. According to incomplete statistics, the tea leaves abandoned and collected in China each year have about 70% of the total yield. However, China still has a large amount of land for planting tea leaves, so the problem of picking fresh tea leaves of famous tea leaves is solved, which is the original intention of the invention!

The whole process of manually picking tea leaves is researched and decomposed, and the picking action is completed by 3 steps of pinching the target, bending the target to about 90 degrees and lifting the target. This action relies solely on the brittle and tender breakage of the plant shoots rather than pinching or shearing.

However, the current automatic tea plucking machine still has the problems to be solved in the using process:

1. because the crushed leaves are not sorted, the rotating speed of the picking device is reduced for better ensuring the complete young shoot rate of the raw materials, and the efficiency is not high;

2. although the rotating speed is reduced, the problem of crushed leaves cannot be solved fundamentally, the ratio of the crushed leaves as the raw material is high, and the quality of the fresh leaves is low;

3. because the broken leaves are not sorted, the small circular arc is designed at the pivot of the breaker, the broken leaves are easier to generate because of the sharp pivot, and the small circular arc reduces the generation of the broken leaves, but also reduces the picking rate of the tea leaves.
