[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the electric speed control mechanism of the harvester is reasonably designed and easy to operate. By setting a motor combination for driving, the fan air volume can be increased or decreased by controlling the forward and reverse rotation of the motor, and the threshing and separation effect can be observed in real time.
