The present invention provides a rubber half track walking device for a combine harvester, wherein the internal shaft seat assembly is matched with the receiving plate seat to form a support, and the joint bearing seat assembly is matched with the driving wheel shaft head to form a support;

The half track walking device of a combine harvester belongs to the track assembly for agricultural machinery, which is composed of a track driving wheel, a supporting wheel, a tensioning wheel, a rubber track, and a walking bracket. The driving wheel is fixedly connected to the driving motor. The front tensioning wheel, the rear tensioning wheel, and the driving wheel are supported on the same vertical plane by the walking bracket in a triangular shape. The supporting wheel is connected below the track at the bottom of the walking bracket, and the rubber track surrounds the driving wheel. The front tensioning wheel is supported by the walking bracket, After the above technical improvements, this utility model has achieved the following beneficial effects: simple structure, easy production, low manufacturing cost, good shock absorption effect, lightweight quality, good anti sinking effect, energy conservation, strong flexibility, and high harvesting efficiency
