A kind of working method of green tea screening machine

Abstract

The invention relates to a working method of a green tea screening machine. The green tea screening machine comprises: a hopper, an electric valve arranged on the discharge port at the bottom of the hopper, a screening frame provided below the discharge port, and a screening frame arranged up and down The upper and lower sieves; the mesh size of the upper sieve is suitable for sieving leaves and leaf stems with a length greater than 3cm; the mesh size of the lower sieve is suitable for sieving leaves and leaf stems with a length greater than 0.5cm ; Below the left end of the screening frame is provided with a rotating arm, one end of the rotating arm is connected to the end bearing of a transmission shaft, and the other end of the rotating arm is fixedly connected to the output shaft of a motor; the transmission shaft is located on the screen The bottom of the frame; when the control motor drives the rotating arm to rotate, the upper and lower screens are suitable for rapid displacement left and right, and at the same time, the left ends of the upper and lower screens are suitable for rapid displacement up and down, so that the green tea on the upper and lower screens can be quickly moved. sieve.

Description

[0001] This application is a divisional application, the application number of the original application: 2013100889213, the application date: 2013-3-19, and the name of the invention: tea green screening machine. technical field [0002] The invention relates to a working method of a green tea screening machine, which belongs to the technical field of agricultural machinery.
