Screening machine for tea leaf processing

Abstract

The invention discloses a screening machine for tea leaf processing. The screening machine structurally comprises a screening box, a telescopic movable grading and screening mechanism, screen fixators, chip discharge hoppers, tea leaf outlet hoppers, a base, a dedusting fan, a transmission case, a discharge box and a rack, wherein the dedusting fan is fixedly arranged on the base and is connectedwith the screening box; and the base and the rack are welded and are perpendicular to each other. According to the screening machine, a reciprocating telescopic rod is driven to move in the left-rightdirection through rotation of a large driving wheel and a small driving wheel, a main screen performs linear reciprocating swinging while vibrating through a sliding block and a self-translation vibrator according to connection of the reciprocating telescopic rod and the sliding block, the vibration range and vibration amplitude are increased, tea leaves can be fully graded and screened, screening force is strengthened, practicability is high, the tea leaves are screened from a feeding pipe to a falling hopper, a waterfall type falling channel is formed, the tea leaves are better protected, and surfaces are prevented from being damaged.

Description

technical field [0001] The invention relates to a screening machine for tea processing, which belongs to the technical field of screening machines for tea processing. Background technique [0002] An important indicator for evaluating the quality of fresh tea leaves is evenness. Uniformity refers to the degree of consistency in the physical and chemical shape of a batch of fresh tea leaves. No matter what kind of tea, fresh tea leaves are required to have good uniformity. If the quality of fresh tea leaves is mixed, the tea making technology will be at a loss. At present, tea screening equipment is mainly used to screen and classify fresh tea leaves. [0003] Sieving is a method of separating particle groups according to particle size, specific gravity, chargeability, magnetic properties and other powder properties. 2. Using a sieve surface with holes to divide the mixed materials with different particle sizes into various particle size levels is called screening. [000...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a sieving machine for tea processing to solve the problem that the existing sieving machine for tea processing has a small vibration range and vibration amplitude, and cannot fully grade and sieve the tea leaves. During the sieving process, it is easy to cause damage to the surface due to the thinness and brittleness of the tea leaves
