The technical scheme of the invention is as follows: the leaf stripping knife set comprises a circular knife disc, wherein a U-shaped knife rest is fixed on the knife disc and comprises a long plate, a short plate and a turning part, wherein the long plate and the short plate are parallel to the knife disc, and the turning part is connected with one end of the long plate and one end of the short plate; the U-shaped knife rest is connected with a leaf peeling knife, the leaf peeling knife is parallel to the long plate and the short plate and hinged between the long plate and the short plate through a cross rod, a baffle plate which is vertically connected with the long plate and the short plate is arranged on the lower side of the cutting edge of the U-shaped knife rest and the lower side of the cutting edge of the leaf peeling knife, and the baffle plate is not longer than the short plate; the blade of the leaf stripping knife is provided with an extension spring which is connected to a cutter head at the lower side of the leaf stripping knife.
When the sugarcane stripper is used, the design of the short plate and the long plate can deviate the leaf stripping knife towards the direction of the short plate, so that sugarcane cutting is avoided. The design of the baffle and the extension spring ensures that the leaf stripping knife rotates along with the cutter head, when the leaf stripping knife contacts sugarcane, the resistance is large, and the leaf stripping is deviated upwards, so that the sugarcane is prevented from being cut; when the sugarcane leaves are touched, the resistance is small, and the leaf stripping knife cuts the sugarcane leaves; the baffle can prevent the leaf stripping knife from deviating downwards.
Further, the leaf stripping knife comprises an arc knife and a triangular knife, wherein the arc knife is a knife edge which is bent in the horizontal direction, the triangular knife is a triangle edge, and the knife edge is an inward concave arc. The length of the triangular knife is smaller than that of the arc-shaped knife. The arc-shaped knife can be attached to the sugarcane column to cut the side face, and the triangular knife can be attached to the sugarcane arc-shaped face closest to the cutterhead to cut. The arc-shaped knife is matched with the triangular knife, so that three-sided laminating and cutting can be carried out on the sugarcane column.
Further, the bending position of the arc-shaped knife is connected with an arc-shaped thorn in the same direction, and the arc-shaped thorn can be retracted into the arc-shaped knife through the torsion spring. The arc thorns are designed to be convenient for separating sugarcane from sugarcane leaves when the leaf stripping knife cuts, and can retract into the leaf stripping knife when the resistance to the sugarcane becomes large.
