[0076] Since the threshing assembly usually needs to be tilted, using gravity and the inclination angle to make the corn kernels slide from high to low in the threshing assembly, the left threshing pulley 511 and the right threshing pulley 521 of the threshing assembly have a certain inclination angle, and the crushing rotor pulley 44 of the crushing assembly is usually placed upright relative to the horizontal plane. The threshing assembly and the crushing assembly are combined in one device and driven by only one motor 1.
