Technical Field

The application relates to the technical field of engineering machinery power control, in particular to a land leveler accelerator control method, a land leveler accelerator control device and a land leveler.

Background

At present, the speed regulation control mode of the engine has two modes of whole-course speed regulation and torque control speed regulation. When the torque control mode changes along with the load and the rotating speed, the fuel injection quantity is adjusted according to the torque map, and the method is suitable for the walking working conditions of trucks, buses and cranes. The pedal opening is fixed in the whole-course speed regulation mode, the engine rotating speed is stabilized at a constant rotating speed, constant rotating speed output is guaranteed, and the method is suitable for industries of power generation, bulldozers, road rollers, land levelers and the like with constant rotating speed output and hoisting working modes of cranes.

The crane industry applies an accelerator change-over switch, a walking mode torque control mode is realized, and a working mode (parking hoisting) adopts a full-range speed regulation mode. Because the crane works, the whole crane is in a static state, and the operation can be conveniently finished through the accelerator selector switch. However, in the wheel-type engineering machinery such as a land leveler, the working condition and the walking condition are overlapped, and the accelerator change-over switch is frequently operated and cannot be applied. Therefore, the existing land leveller applies a whole-course speed regulation strategy, but the land leveller has a large number of driving working conditions (backing, transition and the like) during working, and under the driving working conditions, the existing land leveller applies the whole-course speed regulation, and has the defects of unreasonable matching of pedal operation (rotating speed control) and vehicle speed, uncomfortable running of the whole vehicle and high oil consumption.
