The stirring rod 10 flips while contacting the tea leaves. At this time, the cylinder 13 also drives the ring 20 to move. The ring The displacement 20 drives the slider 16 to slide in the inner cavity of the slide groove 12 through the square plate 18, and at the same time drives the scraper 14 to displace the tea leaves on both sides of the structural plate 5 and the top of the spreading plate 3, effectively scraping the tea leaves accumulated on both sides of the structural plate 5 and the top 3 of the spreading plate, and mixing it with the tea leaves in other parts to further promote the uniform spreading of the tea leaves. The personnel pulls the handle 2, opens the baffle 4, and takes out the tea leaves. The personnel starts the motor 9, and driven by the scraper 14, the tea leaves remaining on both sides of the structural plate 5 and the top of the spreading plate 3 are scraped off and collected, thereby avoiding the waste of tea leaves.
