Description

Broken tea plucker

Technical Field

The invention relates to a tea plucker, in particular to a broken tea plucker.

Background

China is a country of origin of tea leaves, and the tea production history is long, wherein the tea leaves are divided into six categories according to the manufacturing process, and the categories are as follows: green, red, white, yellow, cyan, black. The ratio of green tea to black tea is about 80%. The quality of fresh leaves (raw material) is often extremely high before green tea and black tea are made. Such as: the bud leaves are required to be complete (too many broken leaves are not good enough), the specification is required to be even (the lengths are not uniform and good enough), the color is not required to be mixed (old leaves and fresh leaves are not good enough to be damaged), and the like. At present, reciprocating tea pluckers are available on the market, but because all the tea leaves entering the shearing range are completely sheared, the fresh tea leaves sheared by the reciprocating tea pluckers are mixed raw materials comprising new tips, old leaves, tea stems (old branches) and the like which can be used for making tea, and if the raw materials are yellow tea and white tea, about 90 percent of the tea leaves are not qualified or even 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 newly planting tea leaves, so the problem of picking fresh tea leaves of famous tea needs to be solved.

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 is totally dependent on the brittle and tender breakage of the plant shoot, rather than pinching or shearing (if pinching or shearing directly, more of the leaf-stem vein is destroyed, resulting in severe loss of fluid from the shoot).

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

the prior art has the following disadvantages:

1. because there is no broken leaf sorting function, 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 raw materials 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.

4. Although the flexible material is designed at the position for pinching the target, the flexible material has limited deformation space, and when two leaves and stems are overlapped and rolled in simultaneously, the leaves and stems of the tea leaves can be crushed, so that the quality of the fresh leaves is reduced.

5. And the deflector rod bracket is exposed at the two ends of the collector. The support which is exposed and rotates is positioned outside the effective picking caliber, which is not only helpful for the picking process, but also can crush tea leaves outside the picking caliber to damage the tea leaves.

6. The rotating speed of the motor is not adjustable, because the tea leaves in different seasons, different time periods, different geographical environments and different varieties have different crispness and tenderness, for example, the tea leaves growing in the morning, spring and high-humidity environment have crispness and tenderness, the rotating speed needs to be slow, and the tea leaves are easily damaged too fast; in addition, for tea grown in dry environment in noon, summer, the rotation speed is slightly faster during picking, and the tea is easy to break.

7. The bottom of the tea plucking machine is a section of circular arc, so that the datum point is difficult to grasp in the plucking process, and the tea shed surface cannot be used by force, so that the labor intensity is increased.

8. When the deflector rod is picked in cooperation with the breaker, in order to prolong the service life, bearings are additionally arranged at two ends of the deflector rod and used for improving the wear resistance, but the bearings collide with the breaker for about 600 times per minute, and great noise is generated.
