Bionic disc tool for cutting crop stalks

The invention discloses a bionic disc tool for cutting crop stalks, and belongs to the field of agricultural machines. The bionic disc tool comprises a first tool disc and a second tool disc which oppositely rotate. Each of the first tool disc and the second tool disc is composed of a rotation disc and cutting blades. The shapes of the cutting blades are of an arc curve structure. A plurality of toothed structures are continuously arranged on a curve of a cutting edge of each cutting blade. According to the bionic disc tool, the arc outline of the propodeum tibia of the mantis and the outer edge armature geometric structure and the arrangement form of the mantis serve as a bionic archetype, and the cutting face shape and the bionic toothed cutting edge structure of the cutting blades in the disc tool are designed; and compared with a traditional disc tool, by means of the bionic disc tool for cutting the crop stalks, the power consumption of cutting work can be reduced by about 10%. 本发明公开了种用于切割作物茎秆的仿生圆盘刀具，属于农
