Unmanned Four-Wheel Independent Electric Drive High Ground Clearance Sprayer is Available

In the on-site meeting held at the Jiangsu Baima Smart Farm Demonstration Base, a new type of unmanned four-wheel independent electric drive high ground clearance sprayer was displayed.

In view of the problem that the chassis of the sprayer with high ground clearance is easy to fall into mud and deep ditch when walking in the paddy field environment, the machine adopts the self-steering electric chassis of the front and rear axles with self-designed special structure to ensure that the tangential movement of the driving wheel in the plane of its motion trajectory greatly reduces the The small steering resistance eliminates the complex mechanical transmission structure of the traditional agricultural machinery equipment chassis, and solves the problem that it is difficult to escape due to the increase of steering resistance when the driving wheel of the traditional steering system sinks. Modeling, observation, parameter identification and control are carried out according to the characteristics of the self-steering structure system, and based on real-time positioning, path planning and tracking control, the front and rear wheels coincide trajectories during the straight-forward and steering operations, reducing the rolling of crops and realizing the whole process without Humanized work.
