AI Technical Summary
During the tea production process, stems and leaves can easily remain at the bottom of the sieve plate, causing blockage and reducing separation efficiency.
A tea stem and leaf separator was designed, which includes a scraping mechanism and a cylinder-driven screening plate. The motor drives the lead screw and scraper to remove residual stems and leaves from the bottom of the screening plate, and the cylinder drives the screening plate to move for screening. The stems and leaves fall directly onto the feeding inclined plate, and the leaves are discharged through the discharge hopper.
It effectively removes stems and leaves from the bottom of the sieve plate, preventing blockages and improving the efficiency of tea leaf separation.
