AUTOMATIC CONTROL SYSTEM OF WORKING MEMBER OF EARTH-MOVING MACHINE Russian patent published in 2007 - IPC E02F9/20 

FIELD: earth-moving machinery.

SUBSTANCE: invention relates to automation of working processes of earth-moving machines. Proposed system contains machine actual speed pickup, soil volume pickup, physical and mechanical properties pickup of soil before working member of earth-moving machine, reference signal shaper, control unit including input device, fixed memory to outputs of which single-chip microcontroller is connected which is connected by its output to output device, and actuating mechanism consisting of electric spools connected by input to output device, and hydraulic cylinders connected by input to output of electric spools which control working member. Outputs of actual speed pickup, pickup of physical and mechanical properties of soil before working member, soil volume pickup and reference signal setter are connected to input of input device, and single-chip microcontroller has feedback with input device, fixed memory and output device.

EFFECT: improved accuracy of automatic control of earth-moving machine working member.
