Leveling chassis of electrically-driven mountain and hill small corn kernel harvester

The invention discloses a leveling chassis of an electrically-driven mountain and hill small corn kernel harvester, and aims to solve the problems that an existing corn harvester is difficult to operate in mountain and hill areas, has the risk of rollover, is large in vibration in the operation process, pollutes the field environment and the like. The chassis comprises an upper chassis frame assembly, a middle chassis frame assembly, a lower chassis frame assembly and a walking steering assembly. Two hydraulic oil cylinders are installed between the upper chassis frame assembly and the middle chassis frame assembly in the front-back direction and are responsible for left-right longitudinal leveling of a harvester body. Two hydraulic oil cylinders are installed between the middle chassis frame assembly and the lower chassis frame assembly in the left-right direction and are responsible for front-back longitudinal leveling of a harvester body. Leveling in the two directions does not interfere with each other. T
