Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

Referring to the small-sized corn stalk cutting machine shown in Figures 1 to 4, it includes a power part, a harvesting part and a body part. 9 The vertical driving shaft 7 and driven shaft 8 are installed through the bearing 4, the upper ends of the driving shaft 7 and the driven shaft 8 are connected to the pulley 2 through a belt, and a number of throwing claws are uniformly arranged on the outside of the belt 3. The throwing claw 3 is a long strip hard structure, which is vertically fixed on the outside of the belt; the lower ends of the driving shaft 7 and the driven shaft 8 are equipped with cutting knives 10, and the cutting knives 10 are uniformly arranged with a number of arc-shaped The flange structure of the blade; on the side where the driving shaft 7 is set on the support platform 9, a reel 5 is also provided, and the reel 5 is a wheel-shaped structure with long teeth, which is fixed on the support platform by a bracket 6 9, driven by the drive shaft 7 to rotate by the belt.
