FIELD: process engineering.
SUBSTANCE: invention relates to drilling, particularly, to machine designed to drill wells in soil. Machine comprises carrier with hydraulic feed device, mast, skids displacing along said mast and skids driving hydraulic cylinder with piston with rod sliding therein. Note here that piston rod is secured at the mast while cylinder body is secured at said skids. One hydraulic control valve is secured at said skids and connected via at least one feed line and at least one central drain line with hydraulic feed device. Said hydraulic control valve is equipped with at least one hydraulic cylinder connector and at least one extra connector for drive motor at skids. Hydraulic cylinder is connected via hydraulic connector for hydraulic cylinder at skids with hydraulic feed device.
EFFECT: higher stability of the machine, ruled out overloads at hydraulic lines, minimised length of flexible movable hydraulic pipelines.
