Screening device for producing tea leaves

Abstract

The invention discloses a screening device for producing tea leaves. The screening device comprises a screening box, a fixing plate is connected to the inner wall of the bottom end of the screening box, a collecting groove is formed in the top end of the fixing plate in the length direction of the fixing plate, a first connecting plate and a second connecting plate are arranged at the top end of the fixing plate, and first grooves are formed in the side walls of one sides, close to each other, of the first connecting plate and the second connecting plate along the length direction of the firstconnecting plate and the second connecting plate; second grooves are formed in the top end and the side wall the bottom end of the first grooves, the side walls of one sides of the second grooves areconnected with telescopic rods, the other ends of the telescopic rods are vertically welded to pressing plates, and push plates are vertically welded to the side walls of one sides of the pressing plates; and the ends, away from the pressing plates, of the pushing plates extend to the outer parts of the first grooves and are connected with first screws which are symmetrically arranged. Accordingto the screening device, sieves with different filtration hole diameters can be replaced according to screening requirements, so that the practicability of the screening device is greatly improved, the sieves can be quickly moved left and right, traditional manual shaking is replaced, and the labor intensity of a worker is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of tea production, in particular to a screening device for tea production. Background technique [0002] Tea, shrubs or small trees, young branches glabrous. Leaves are leathery, oblong or elliptic, with blunt or sharp apex, cuneate base, shiny upper surface, glabrous or pilose at the beginning, serrated edges, petiole glabrous. Flowers white, petiole sometimes slightly longer; sepals broadly ovate to round, glabrous, persistent; petals broadly ovate, base slightly conjoined, back glabrous, sometimes pubescent; ovary densely white haired; style hairless. Capsules 3-globose or 1-2 globose, 1.1-1.5 cm high, with 1-2 seeds per bulb. The flowering period is from October to February of the following year.

AI Technical Summary

Problems solved by technology

[0003] In the traditional tea production process, it needs to be screened and processed. The traditional screening is to use a sieve to screen tea leaves of different sizes. The worker shakes the sieve left and right to separate the tea leaves of different sizes. The efficiency is low, the diameter of the traditional sieve is fixed, and it is impossible to change the diameter of different filter holes according to the screening requirements, and when the traditional sieve is shaken from side to side, the tea leaves are easy to fly out of the sieve and fall to the ground. Therefore, we propose a Screening device for tea production
