Description

Technical Field

[0001] The utility model relates to the technical field of tea production and processing, in particular to a stepped tea stalk picking device for tea production. Background Technique

[0002] Tea is very popular among consumers due to its special advantages such as refreshing the mind, diuresis and detumescence, and preventing heatstroke. In the actual production and processing of tea, a sieve and stalk picking device is often needed, which can realize the screening and optimization of tea. However, there are still some defects in the actual operation of such tea stalk picking devices for tea production.

[0003] The tea stalk picking device for tea production often realizes the separation of tea and tea stalks and other impurities through a single vibrating sieve mesh, which has insufficient screening fineness and poor processing effect. Moreover, after one screening process, the user still needs to collect the tea on the sieve mesh and the tea stalks that fall to the ground, which has the problem of inconvenient material collection. Based on this, we propose a new stepped tea stalk picking device for tea production, which can not only realize the multi-stage screening function, but also quickly and independently disassemble and assemble each sieve mesh structure, facilitate the classification and extraction of tea and tea stalks, etc., and improve the operation convenience.
