Automatic leveling device and control method for automatic leveling and automatic height limiting
The invention relates to the technical field of working machines, in particular to an automatic leveling device and a control method for automatic leveling and automatic height limiting. The automaticleveling device comprises working devices, an accessory, first actuators and a hydraulic control system, wherein the working devices are assembled in a hinged manner, and angle sensors are used for detecting the angle of the working devices to obtain the deflection angle A of the working devices; the accessory is assembled at the free ends of the working devices in a hinged manner; the telescopicends of the first actuators are hinged to the accessory, and the accessory can be driven by the first actuators to deflect relative to the working devices; and the hydraulic control system comprisesa hydraulic pump, the hydraulic pump is controlled by a first control valve to supply oil to the first actuators, the first control valve is controlled by a first electric proportional pressure reducing valve to reverse, and an electrical signal is applied to the first electric proportional pressure reducing valve according to the deflection angle of the working devices to level the accessory in real time. The technical problems of leveling structure complexity, pipeline complexity and high cost of a carry-scraper in the prior art are solved.
