    In a method of and device for adjusting the feed movement of a drill rod for drilling a rock, the drill rod is rotated by a pressure-medium-operated rotary motor and fed in a drilling direction and in the opposite direction by a pressure-medium-operated feed motor. A pressure change on the pressure side of the rotary motor due to a change in the rotation resistance on the rotary motor acts oppositely on the pressure and outlet sides of the feed motor toward reversing the feed force of the feed motor, i.e. in inverse and direct dependence on the pressure change, respectively. The pressures on the pressure side and the outlet side of the feed motor are, therefore, controlled so that, when the pressure on one side increases because of the pressure change, the pressure on the other side decreases and vice versa.

    It is rotated by a hydraulic motor 5, which in one embodiment of the boring machine can be reversible. A vibrator (not shown) driven by a hydraulic motor 6 is installed in the drilling machine to drill hard rocks. The hydraulic motor 1 of the feeder is connected to the hydraulic pump 9, which is connected to the hydraulic motor 5 of the rotator by hydraulic lines 5 and 8. The hydraulic motor 5 rotator drain line 12 is connected to the tank for collecting oil (not labeled). The drain line of the hydraulic motor 1 of the feeder by line 13 (FIG. 1) is connected to the pressure line 10 of the hydraulic motor 5 rotator. In the pressure line 7 of the hydraulic motor 1 of the feeder, a control valve 14 is installed, which in one of its extreme positions connects the pressure line 7 through line 8 to the hydraulic pump 9, and in another position connects the line 7 through pipeline 15 to the tank. A pipe 16 connects the line 13 to the control channel 17 of the control valve 14, which is connected to the controller 18 to set the value of the control signal.
    In another embodiment (Fig. 2) of the hydraulic drilling machine, a throttle valve 19 is installed in the drain line 12 of the hydraulic motor 5 rotator, which is located in the area between its connection through the pipeline 20 to the control valve control channel 17 and the tank.
    When executing the hydraulic circuit of a drilling machine with a reversible hydraulic motor 5, the rotator of the latter is carried out by moving the handle of the hydraulic distributor 21 mounted parallel to the reversible hydraulic motor 5 (Fig. 7). In this case, an additional valve 22 is installed parallel to the hydraulic motor 5, which is installed with the possibility of connecting the pressure line of the rotary motor hydraulic motor 5 to the control valve control channel 17 via the pipeline 1.3 and pipeline 16 (FIG. 3).
     When executing the hydraulic circuit of the drilling machine with control from the drain line of the reversing hydraulic motor 5 rotator (FIG. 5) parallel to the hydraulic motor 5 rotator; An additional valve 23 is installed, which is placed with the possibility of connecting the drain line of the hydraulic motor 5 to the control valve control channel 17 by means of pipeline 20, and the connection of the main line 13 to the hydraulic engine pressure line 5 provides an additional valve 22 installed in parallel with the hydraulic motor 5.
    The hydraulic circuit of the drilling machine includes control valves 24, which are installed in the pressure 11 and drain 12 lines of the reversing hydraulic motor 5 rotator (Fig. 7). To limit the maximum pressure in the hydraulic system at the outlet of the hydraulic pump 9, a safety valve 25 is installed. Optimum working fluid pressure in the pressure line of the hydraulic motor 1, the feeder is installed by means of a valve 26 located in the pressure line 8. By means of the hydraulic distributors 27 and 28, the control is carried out according to Feeder-retarded hydraulic motor 1 and the hydraulic motor 6 of the vibrator. To ensure the possibility of extracting the drill rod 3 using manual control, the line 13 is connected via a check valve 29, installed in the line 30, and the hydraulic distributor 27 with the hydraulic pump 9, while

    removing the drill rod 3 along the pressure line 7 and 8, the working fluid is drained into the tank, for which a check valve 31 located in the pipeline 32 is installed parallel to the valve-regulator 14, and a check valve 33 is installed in parallel to the valve 26 water piping 34.
    As one of the options for reversing the hydraulic motor 5 rotator, a hydraulic distributor 35 may be included in the hydraulic circuit, mounted parallel to the hydraulic motor 5 (Fig. 4 and 6).
    Hydraulic drilling works as follows.
    In the mode of drilling rocks (Fig, 8)
    The 20 hydraulic pump 9 supplies the working medium under pressure to the hydraulic motor 1 of the feeder through the hydraulic distributor 27 and valve 26, via the main pipe 8, through the regulator valve 14 and through the hydraulic circuit 7. The passage of the working fluid through the hydraulic motor 1 ensures its rotation and, therefore , the flow of the rotator 2 with the drill rod 3 on the frame 4 of the feeder in the direction of

    line 13 is below the pressure of the working fluid in line 7. The working fluid through line 13 enters the pressure line 10 of the hydraulic motor 5 rotator. Since the operation of the hydraulic engine 5 requires a much larger amount of energy; than from hydraulic engine 1, an additional amount of working fluid enters through line 1I through regulating valve 24 and hydraulic valve 21 from hydraulic pump 9. At the same time, the difference in pressure of working fluid in lines 7 and 13 corresponds to the specified axial force on the drill rod 3 in the optimum mode of drilling, and the flow rate of the working fluid entering the hydraulic motor 5 corresponds to the optimum rotational speed of the drill rod 3 and is equal to the sum of the flow rates of the working fluid flowing through line 11 and 13. In this case The rotational speed of the hydraulic motor 5 is controlled by changing the flow area of the throttles of the valve 24. Simultaneously with the rotation of the hydraulic motor 5 by turning on the hy, cc: distributor 28, it can be actuated by a hydraulic motor 6; a vibrator. At the same time, the area of the control channel 17 of the valve-regulator 1A, acting on the valve stem-regulator 14, and the spring force of the regulator 8, acting on its rod, are chosen so that during normal drilling the pressure of the working fluid in line 7 is equal to or slightly lower than the pressure of the working fluid in line 8, i.e. pass

    If, during drilling, the drill bit 3 hits a crack or loose rock zone, the resistance to rotation of the drill rod 3) increases, and with increasing resistance to rotation of the hydraulic motor 5, the pressure of the working fluid in the pressure line 10 and 11, line 13 and ; Pipeline 16 immediately ages - I W (Fig. 9). At the same time, the pressure in the mains; 13 increases - software is compared with the value of pressure in this line during normal drilling; iIncreased pressure in the pipe | 16 connected to the control channel 17; lazy control valve 14, The movement of the rod of the latter in the direction of reducing the flow area of the valve-regulator 14, as a result of which the pressure of the working fluid in the line 7 decreases. Thus, by increasing the pressure of the working fluid in line 13 and reducing the pressure of the working fluid, the required torque is reduced by the hydraulic motor 1 ", i.e., the axial load on the drill rod 3, which, in turn, prevents jamming drill rod 3. If, despite the described reduction of the axial load on the drill rod 3, the resistance to rotation of the drill rod 3 increases, then the control valve 14 fully transits the flow area between lines 7 and 8 and connects the line through pipe 15 to the tank. In this case, the pressure of the working fluid in line 13 becomes higher than the pressure in line 7, which in this case becomes a drain, as a result
    the direction of rotation of the reversible hydraulic motor 1 of the feeder and changes to the opposite, which ensures the movement of the rotator 2 with the drill rod 3 from the zone of sedimented loose rock.
    In another embodiment, the design of hydro,. Equal boring machine (Fig. 2)
    during operation of the hydraulic motor 5 of the rotator, the working fluid passing through the drain line 12 creates a pressure drop across the throttle 19. In the case of a small resistance to rotation of the drill rod 3, the flow of working fluid in the drain line is sufficiently intense, which allows to maintain the pressure in the control channel 17 of the valve-regulator 14, sufficient to hold the valve stem 1a-controller 14 in the position providing the maximum the cross-section connecting lines 7 and 8. In the event of an increase in the resistance to rotation of the hydraulic motor 5 of the rotator, the pressure drop across the throttle 19 decreases. oprovode 20 causes movement of the valve stem, the regulator 14 under the action of the spring adjuster 18 that provides for sufficient magnitude resistance to the rotation of hydraulic motor 5 rotator change the direction of rotation of hydraulic motor 1 po0

    sensor on the opposite as
    in the previously considered embodiment, in the design of the boring machine.
     When the rotary motor 5 is reversible (FIG. 3), the operation of the boring machine proceeds in a similar way an additional valve 22 of type OR ensures the connection of the main 10 or the main 12, i.e. the one that is currently the pressure line of the hydraulic motor 5 rotator with the channel 17 of the control valve 14.
    Similarly, the work of the drilling machine with a reversible hydraulic motor 5 rotator and regulation from its drain line - 5 line (Fig. 5). At the same time, with the help of an additional valve 23, the control valve control channel 17 is automatically connected to one of the lines 10 or 12, i.e. that

    which, with this direction of rotation of the hydraulic engine 5, is a drain line, and valve 22 connects the line 13 to another line 12 or 10, which, at the indicated direction of rotation of the hydraulic engine 5, is pressure-driven. At the same time, the working fluid in the discharge line is supported by throttles 19 installed in lines II and 12, and for the unimpeded passage of the working liquid in the pressure line parallel check valves are installed parallel to the throttles m 19.
    When used for reversing the hydraulic motor 5 rotator of the hydraulic distributor 35 (Fig. 4 and 6), the operation of the hydraulic drilling machine does not differ from that described earlier.
    As the hydraulic motor 1 of the feeder drive, a hydraulic cylinder or some other displacing device can be used.
