The steering wheel body is arranged on the connecting rod mechanism, and the connecting rod mechanism is hinged with a mounting plate. The mounting plate and the driving part one are used to connect the vehicle body frame. The piston rod of the driving part one is hinged with the connecting rod mechanism, and the hinge shaft of the driving part one is arranged in a spaced manner with the hinge shaft of the mounting plate. When the vehicle is in manual driving mode, the piston rod of the driving part one is extended, which drives the connecting rod mechanism to rotate and move closer to the driver, thereby driving the steering wheel body to move closer to the driver. When the vehicle is in unmanned driving mode, the piston rod of the driving part one is retracted, which drives the steering wheel body to move away from the driver through the connecting rod mechanism, thereby increasing the activity space of the driver and enabling the driver to turn around and communicate with the rear passengers. However, the traditional harvester steering wheel mostly travels in the field, and the vibration during travel is large, making it difficult to control the steering wheel. It is difficult to operate the steering wheel for a long time, so an unmanned agricultural harvester steering wheel structure is proposed to solve the above problems. SUMMARY
