Fresh leaf grading device for grading fresh tea leaves and tea leaf picker

Abstract

The invention relates to the technical field of tea leaf picking, in particular to a fresh leaf grading device for grading fresh tea leaves and a tea leaf picker. The fresh leaf grading device comprises a grading sieve, wherein a plurality of sieve meshes are formed in the grading sieve, the sizes of the sieve meshes are matched with fresh tea leaves with one bud on one leaf, the grading sieve isobliquely arranged, and the lower end of the grading sieve is in clearance fit with a picking assembly and the tea leaf picker, so that tea leaves picked by the picking assembly are located above thegrading sieve; the tea leaf picker has two discharging ports including a first discharging port located on the upper side and a second discharging port located below the first discharging port, collecting assemblies are arranged at the first discharging port and the second discharging port, and the higher end of the grading sieve is arranged on the lower edge of the first discharging port. By means of the fresh leaf grading device, follow-up grading work is substantially facilitated, besides, the sieved tender leaves and buds are separately transported, and the damage risk in the turnover process is reduced.

Description

technical field [0001] The invention relates to the technical field of tea picking, in particular to a fresh leaf grading device and a tea picking machine for grading fresh tea leaves. Background technique [0002] my country is a big country of tea production and consumption. As a natural green drink, tea has a long cultural tradition in our country. Chinese green tea not only has the most famous products, but also has excellent quality, unique and beautiful shape, and has good artistic appreciation value. It is becoming more and more popular.

[0006] The current tea picking machines use the blade assembly to cut the tea leaves from the tea tree, so as to realize the picking of the tea leaves. During the picking process, the high-quality leaf buds such as young buds and young leaves are cut off together with the old tea leaves and even the branches. , although high-quality leaf buds with low leaf age can be screened out through grading and screening in the future, but the process is responsible and requires a lot of manpower and material resources. Moreover, the current grading and screening is to pack and transport the picked tea leaves to the factory building , when the corresponding grading equipment is used for grading, during the turnover process, high-quality young leaves and shoots are easily squeezed, damaged and scratched, so the varieties of young leaves and shoots screened out are still not high
