The invention discloses a multi-ground-clearance self-steering intelligent
sprayer and a control method. The
sprayer comprises a vehicle platform, two self-steering traveling mechanisms, a controllable lifting spraying device, a
gasoline power generation and supply device and a control device, and each self-steering traveling mechanism is connected with the vehicle platform by adopting a rotation structure; the controllable lifting spraying device is fixed at the
tail of the vehicle platform and comprises a
sprayer lifting mechanism, a spraying rod device and a
drug mixing device, the spraying rod device is arranged on the sprayer lifting mechanism and connected with the
drug mixing device, and a spraying rod can move up and down along with traction of the sprayer lifting mechanism; the
drug mixing device is fixed in the middle of the vehicle platform and provides drug to spraying equipment for spraying, the
gasoline power generation and supply device is fixed on the front portion of the vehicle platform and serves as a stable
voltage power source of the equipment, and the control device is connected with driving equipment, a control motor and multiple sensors. Four hub motors are controlled by the control device to realize self-steering of wheels at differential speeds, and the sprayer is high in control accuracy and small in
turning radius.
