Screening machine for tea leaf processing

Abstract

The invention discloses a screening machine for tea leaf processing. The screening machine for tea leaf processing comprises a box body and a bottom plate, a feeding pipe is arranged on the left sideof the upper end of the box body, a motor frame is arranged on the right side of the upper end of the box body, a motor is arranged at the upper end of the motor frame, a cam is connected to the leftend of the motor through a motor shaft, a movable rod is arranged in the middle of the upper end of the box body, and a pressing block is arranged at the upper end of the movable rod. According to thescreening machine for tea leaf processing, the motor works to enable the cam to act on the pressing block, and the movable rod is made to move downwards; when the cam moves to another position, the movable rod rebounds under the action of second springs, and the movable rod can move up and down so as to drive a coarse screen plate, a middle screen plate and a fine screen plate to shake up and down, and therefore the tea leaves can be screened; the screen plates are in sliding connection with the movable rod through a movable frame, the vibration frequency and the vibration amplitude of the screen plates are further improved, therefore the tea leaf screening efficiency of the screen plates is improved; and different material guide plates are arranged on the right side of the box body corresponding to different screen plates, and therefore collection is facilitated after screening is completed by the screen plates.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a screening machine for tea processing.
