The center of the inner wall of the mounting box 301 is rotatably connected to a driving wheel 302 through a bearing. A servo motor 303 is bolted to the side of the mounting box 301 away from the driving wheel 302. The driver in the servo motor 303 uses a digital signal processor as the control core to realize complex control algorithms, including digitalization, networking and intelligent control.

The end of the transmission connecting piece away from the driven frame 304 is provided with a tea leaf dispersing piece. The tea leaf dispersing piece comprises the processing frame 309 arranged inside the discharge part 2. A distribution grid plate 310 is connected to the inner side wall of the processing frame 309 by screws. The driving servo motor 303 drives the driving wheel 302 to rotate to push the tea leaf dispersing piece to move laterally and reciprocally. The processing frame 309 is arranged below the discharge frame opening 202. The tea leaves discharged from the discharge frame opening 202 fall into the inside of the processing frame 309 and the distribution grid plate 310 in sequence.
