Description

one

The invention relates to drilling machines with a hydraulic drive for feeding and rotating a drill, namely mobile cranes for auger drilling and drilling.

A drive to a well drilling device is known, comprising two independent feed and rotational hydraulic systems with constant-flow pumps, as well as a speed controller, made in the form of a throttling slide valve 1.

The drawback of the device is the loss of power during throttling of the oil through the speed regulator, as well as the transmission of two pumps to each hydraulic system.

A device for feed flow and a rotary drill is contained, containing a drill supply hydraulic cylinder, a drill rotation hydraulic motor, a pump, a control hydraulic control valve, a pressure reducing valve installed in series on the iodachi hydraulic cylinder line, and an oil pipe 2.

This device contributes to the maintenance of a constant torque or variable torque, but does not provide an optimal mode of operation.

In order to increase the productivity of the drill mailina by maintaining the maximum torque on the drill in various ground conditions, the flow force in the main line is automatically changed.

The supply hydraulic cylinder is equipped with a reduction valve Hbiii, the valve is equipped with a valve, (1) valve is connected to a pressure bar with a single pipe and a hydraulic motor.
