Sugarcane harvesting machine and feeding type sugarcane cutting device thereof

The utility model provides a sugarcane harvesting machine and a feeding type sugarcane cutting device of the sugarcane harvesting machine. The sugarcane harvesting machine comprises a rack, a chassis, a power mechanism, a sugarcane lifting device, the feeding type sugarcane cutting device, a section cutting mechanism and a conveying mechanism, wherein the chassis, the power mechanism, the sugarcane lifting device, the feeding type sugarcane cutting device, the section cutting mechanism and the conveying mechanism are installed on the rack. The sugarcane lifting device is located at the front end of the rack. The cutting device, the section cutting mechanism and the conveying mechanism are sequentially arranged behind the sugarcane lifting device. The power mechanism is connected with the cutting device, the section cutting mechanism and the conveying mechanism. The feeding type sugarcane cutting device comprises a power transmission mechanism connected with the power mechanism of the sugarcane harvesting machine, a left cutter disc mechanism connected with the power transmission mechanism, and a right cutter disc mechanism. The right cutter disc mechanism and the left cutter disc mechanism are arranged symmetrically, and the right cutter disc mechanism is connected with the power transmission mechanism. The rotating axis of a cutter of the left cutter disc mechanism and the rotating axis of a cutter of the right cutter disc mechanism are parallel to each other. The rotating circle of the cutter of the left cutter disc mechanism and the rotating circle of the cutter of the right cutter disc mechanism are overlapped to a certain degree.
