RIPPER CUTTING ANGLE CONTROL SYSTEM Russian patent published in 2024 - IPC E02F5/32 E02F9/22 

FIELD: earth-moving machines.

SUBSTANCE: invention relates to excavation equipment, for example, to rippers, and in particular to control systems of rippers. Ripper cutting angle control system includes hydraulic pump, hydraulic tank, hydraulic cylinder of cutting angle change, stock cavity of which is interconnected with hydraulic accumulator, hydraulic control valve with electromagnetic control, which is connected to control unit. System is equipped with theoretical and actual speed sensors, a hydropneumatic damper, an adjustable pressure reducing valve, an adjustable hydraulic throttle, a check hydraulic valve and an electric switch. Sensors of theoretical and actual speed are connected by electric lines to control unit. Hydropneumatic damper is interconnected via controlled hydraulic throttle and parallel connected check hydraulic valve with piston cavity of hydraulic cylinder for change of cutting angle. And the controlled pressure reducing valve is connected to the hydraulic accumulator by the outlet and to the pressure hydraulic line by the inlet. Electric switch is connected with electromagnets of the hydraulic control valve.

EFFECT: increasing productivity, reliability and reducing energy costs.
