Walking driving gearbox device of corn harvester

The walking driving gearbox device of the corn harvester consists of an input connecting shaft device, an auxiliary gearbox device and a main gearbox device, and is mainly characterized in that the auxiliary gearbox device and the input connecting shaft device are additionally arranged on the basis of a gearbox device in the prior art, variable-speed transmission is added through the auxiliary gearbox device, and the walking driving gearbox device is convenient to manufacture and low in cost. The auxiliary gearbox and the main gearbox device are combined to be convenient to use, a variable gear is increased, the gear ratio of the walking driving gearbox device of the corn harvester is improved, and when the corn harvester runs on a large slope or a muddy field, walking resistance is greatly increased, and walking is difficult, the speed reduction ratio is increased through the auxiliary gearbox, and the speed reduction ratio is increased. Therefore, the corn harvester is easy to walk out of the dilemma. 本实用新型
