At present, researchers at home and abroad develop various field operation machines, but in the running process of the existing field operation machines, particularly in the running process of a field road surface with uneven height, a vehicle frame cannot be leveled, so that the working difficulty of operators on the operation machines is increased, the operation efficiency is reduced, and meanwhile, the potential safety hazard is also high, so that the operation vehicle frame has the danger of rollover and pitching.
In order to solve the above technical problems, a plurality of field operation machines capable of leveling a frame are already proposed in the market, for example, patent numbers are: CN114467713B, entitled: the utility model relates to an air-ground cooperative operation water-saving irrigation robot, which comprises a balance system and a control system, wherein the balance system comprises a middle layer plate and at least two electric control lifting devices, and the at least two electric control lifting devices are respectively fixed on two sides of the middle layer plate along the advancing direction of a vertical bottom plate; the control system comprises at least two lower photoelectric sensors, wherein the at least two lower photoelectric sensors are respectively fixed at two sides of the travelling direction of the bottom plate; the two photoelectric sensors can detect whether the ground on two sides of the travelling direction of the bottom plate is level or not, signals are transmitted to the controller, and the controller regulates and controls the two electric control lifting devices to lift according to the transmitted ground information, so that the irrigation system which is safely arranged on the top plate is ensured to be kept level, and the side turning or pitching danger is avoided.
However, in the leveling process of the frame, two sets of photoelectric sensors and two sets of electric control lifting devices are needed, so that the manufacturing cost is obviously too high, and the large-area popularization and application are not facilitated; and only the vehicle frame can be leveled by using an observation means, when the vehicle frame is at night or in a zone which is not easy to observe, the electric control lifting device cannot receive an adjustment signal in time, so that the vehicle frame is inclined abnormally.
