Abstract

The invention discloses a tobacco field operation device. The device comprises a rack, wherein power equipment and a transmission system are arranged on the left side of the rack. The device is in a four-wheeled manner, a driver rides to control the device, and the problems that a single-wheel or two-wheel walking type field operation machine is low in traveling stability and high in operation labor intensity for drivers are solved. According to the device, the trafficability characteristic is improved in an arch bridge type frame structure form instead of a manner of increasing the tire diameter. Two rear wheel rigid supports are arranged on two sides of the rear of the arch bridge type frame, the middle part of the two rear wheel axles is disconnected, and the trafficability characteristic is prevented from being influenced by the fact that the height from the middle part of the two rear wheel axles to the ground is low. The front wheels are elastically fixed on a steering knuckle vertical shaft by a shock absorber, the four wheels are always contacted with the ground during driving, and the condition that the front wheel on one side rises to the sky due to ground fluctuation is avoided. The driver position can be arranged below the left front part, the driving position is low, the manipulation view is good, and the sense of safety is strong.
