At the same time, when the lifting shaft 205 rotates, the synchronous bevel gear 215 is driven to rotate, and the synchronous bevel gear 215 drives the bevel gear 218 to rotate, thereby driving the connecting shaft 216 to rotate, and the connecting shaft 216 rotates to drive the transmission gear 227 to rotate, thereby driving the control gear 229 to rotate, thereby driving the working rack 222 to slide downward, thereby realizing the downward movement of the working plate 223. When 208 stops moving downward, the working plate 223 stops moving at the same time. At this time, the weeding motor 224 starts to work, driving the working disc 225 to rotate, thereby realizing the weeding tool The rotation of 226 realizes the secondary removal of weeds. When the driving shaft 406 rotates, it drives the connecting pulley II 410 to rotate. The connecting pulley II 410 drives the connecting pulley I 307 to rotate through the connecting belt 306, thereby driving the rotating shaft 303 to rotate. The rotation of the rotating shaft 303 drives the fan rotating shafts 308 on both sides to rotate, thereby driving the fan blades 305 to rotate, realizing the movement of the blowing device, and the air enters from the side of the blower 304, and the fan blades 305 inside the blower 304 rotate, thereby blowing the air out, avoiding the accumulation of cut weeds and affecting the progress.
