While vibrating the screen 4, the bottom of the screen 4 can be scraped to scrape the tea leaves adsorbed on the bottom of the screen 4, so that the tea leaves can be better collected, avoiding the blockage of the screen 4 affecting the screening of the tea leaves, reducing the difficulty and cost of subsequent cleaning by personnel, improving the screening efficiency, and extending the service life of the screen 4. Through the cooperation of the pulley 4 8 and the pulley 3 7, while the reciprocating screw rod 2 14 rotates, the reciprocating screw rod 10 rotates, and the reciprocating screw rod 10 cooperates with the screw sleeve A 11 drives the turning claw 13 to turn the tea leaves in the screen 4 back and forth. When the tea leaves are turned, gravity will cause the tea leaves particles to move downward. The tea leaves, as smaller particles, pass through the mesh holes of the screen 4 under the action of gravity and fall into the collecting frame 9. By turning the tea leaves by the turning claw 13, the tea leaves can be more evenly distributed on the screen 4, increasing the contact area between the tea leaves and the screen 4, thereby improving the screening efficiency of the tea leaves.
