HYDRAULIC SYSTEM OF TILLAGE MACHINE Russian patent published in 2022 - IPC B06B1/18 F15B11/15 

FIELD: machine building.

SUBSTANCE: invention relates to vibration equipment and is used in digging machines. Hydraulic system of tillage machine contains hydraulic vibrator, housing of which is rigidly connected to distribution panel equipped with check valves connecting it to channels of rotary distribution slide valve, and hydraulic valve. Distributing slide valve is made in the form of a shaft with pairwise parallel radial holes. Hydraulic valve is installed with possibility of connection of cavities of hydraulic vibrator with working cavities of power hydraulic cylinders, which are connected to each other through additional check valves. Hydraulic system also includes hydraulic accumulator connected to pressure hydraulic line between hydraulic vibrator and additional check valve. In the pressure hydraulic line of the power hydraulic cylinders there is an adjustable throttle with the possibility of supplying the full flow of liquid to the power hydraulic cylinders.

EFFECT: expanded operating performances.
