The motor is used as the supporting power. Power is transmitted to the main shaft, and the gear at the other end of the main shaft transmits the speed-adjusted power to the grass pressing roller through the gear box, universal joint, chain, etc. When the material to be processed enters between the upper and lower grass pressing rollers through the conveyor belt, After being clamped by the grass pressing roller and fed into the guillotine cutting mechanism at a certain speed, it is kneaded by a high-speed rotating kneading device, and then thrown out of the machine by the wind blade through the grass outlet.
