Modification of Triangle Anti Sinking Track Chassis Wheat Harvester

Triangular track wheel, comprising a wheel and a track, wherein the wheel is equipped with a wheel axle, the wheel is covered with an anti pulley, and the anti pulley is fixedly connected to the wheel through a locking buckle. The locking buckle is provided with several evenly distributed inner rings of the anti pulley, and the outer ring of the anti pulley is provided with teeth; The outer side of the wheel is equipped with a triangular support frame composed of telescopic rods, and at each of the three vertices of the triangular support frame, there is a driven wheel axis parallel to the wheel axis. Each driven wheel axis is hinged with a driven wheel. The present invention utilizes the driven wheels hinged at the three vertices of the triangular support frame to enable the wheel to have better walking ability when encountering uneven ground; By using the anti pulley on the outer jacket on the wheels, the vehicle can be prevented from slipping; By cooperating with anti pulley tracks, wheeled vehicles can be transformed into tracked vehicles, which not only exceeds the flexibility and maneuverability of ordinary tracked vehicles, but also improves the vehicle's passing capacity
