SCRAPER LOADING DEVICE CONTROL SYSTEM Russian patent published in 2021 - IPC E02F3/65 E02F9/22 

FIELD: vehicles.

SUBSTANCE: invention relates to trailed earth-moving vehicles with a loading device. The control system of the scraper reloading device contains a hydraulic pump, a reloading cylinder, a hydraulic accumulator and a bucket drive hydraulic cylinder with a hydraulic distributor, an adjustable pressure reducing valve, an electrically controlled two-position hydraulic valve, a direction switch and an adjustable hydraulic throttle. An adjustable hydraulic throttle is included in the hydraulic line connecting the hydraulic accumulator with the hydraulic distributor, which is made four-position with the possibility of communicating the cavity of the bucket hydraulic cylinder lift with the hydraulic accumulator, in one of the positions of the slide valve. The hydraulic accumulator is connected by one hydraulic line with the hydraulic pump through an adjustable pressure reducing valve and the second hydraulic line with the piston cavity of the reloading hydraulic cylinder through an electrically controlled two-position hydraulic valve, while its solenoid is connected by a control line with a travel switch installed on the bucket drive hydraulic cylinder.

EFFECT: increasing reliability, facilitating workflow management, expanding the functionality of the additional loading device.
