A rack pair formed between them drives the annular cutter belt 1 to circulate in one direction along the annular groove under the guidance and support of the guide wheel 13 . During the one-way circular motion, the annular knife belt 1 in the V-shaped structure of the splitter plate moves horizontally relative to the splitter plate 2, as shown in FIG. The dislocation movement of the teeth forms a scissors motion, which cuts off the tea tips of the tea leaves. In the specific implementation, since the tea leaves have been pruned many times during the growth and cultivation, the tea tips of the tea leaves are basically at the same level, so the tea tips can be cut uniformly through the cooperation of the annular knife belt 1 and the leaf splitting plate 2 .

On the other hand, the rotating ends of the shaft member 10 coaxially drive the hexagonal bracket 4 to rotate around the rotation axis, and the six shifting forks 3 on the hexagonal bracket 4 reciprocate in sequence to make a falling movement toward the front side: 3 Drop onto the top of the splitter plate 2, the bottom end of the sparse tooth structure of the shift fork 3 is just flush and close to the top surface of the splitter plate 2, then the shift fork 3 moves backward, and the sparse tooth structure of the shift fork 3 sweeps In the gap between the tea leaves near the splitter plate 2 and the teeth of the splitter plate 2, let the teeth of the annular knife belt 1 cut the tea tips of the tea leaves, and after cutting the tea tips, it will stay on the splitter plate 2 and the tea tips for a short time. The tea buds on the blade tooth surface of the annular blade belt 1 are scraped and swept into the storage box 16 .

Therefore, the movement of the fork 3 of the sweeping impeller 12 and the movement of the annular knife belt 1 are realized by the same motor, and the synchronization of the sweeping blade and the shearing blade is carried out simultaneously and coherently.
