    For reducing the amount of water consumed, supply of water to the cutting head of a cutting machine shall be given free only if different operating conditions are simultaneously occurring. The proposed process contemplates to provide the possibility to supply water to the cutting head only with the rotational movement of the cutting head being switched-on and to give free the water supply only if simultaneously at least one further operating condition such as, for example, a movement of the cutting arm or a movement of the machine is occurring. The apparatus for performing this process contemplates a device for switching-in a water pump, said device being coupled with a device for switching-in the rotational drive of the cutting head. For this purpose, a series of control pistons 2, 3, 4, 5 and 6 are arranged within a common cylinder 1, the working spaces of each individual control piston being connected via conduits 15, 16, 17, 18 and 19 with the working spaces of the associated hydraulic aggregates for the movement of the cutting arm and, respectively, the machine. The control pistons 2, 3, 4, 5 and 6 are coupled one with the other in direction of the pressure supplied and loaded in opposite direction to this direction by a spring 8. Shifting movement of one of the control pistons 2, 3, 4, 5 and 6, which control pistons can be shifted independently one from the other, thus, together with the water pump being switched on, effects release of supply of water to the cutting head (FIG. 1).

    The invention relates to the mining industry, namely to devices for regulating the supply of water to the cutting head of the iron-cutting machine.
    The purpose of the invention is to reduce the water consumption during operation of the cutting machine.
    FIG. 1 shows a device for adjusting the supply of water to the notch head of the cutting machine, a cross-section; in fig. 2 - water shut-off valve with hydraulic piston, cross section.
    The device for regulating the supply of water to the notching head of the cutting machine comprises a cylindrical body 1 with a longitudinal hole 2 under the water distribution mechanism formed from a set of sequentially arranged spools in the form of distribution pistons 3-6. The distribution pistons are interconnected by stops 7 and are pressed to these stops by a spring 8. Used working chambers 9-14 of these pistons are connected to hydraulic pipelines 15-18, which are located in transverse bores 19 and connected to working chambers of various hydraulic units or their pressure pipelines. Each of the pipes 15-18 exits, for example, into the working chamber of a hydraulic cylinder of a cutting machine (not shown), which rotates to the left, right, up and down. The second pipe goes into the working chamber of the hydraulic drive motor (not shown) or into its pressure pipe to move the cutting machine forward
    When electrically driven, an electric motor can drive a pump for supplying a pressure medium, which creates a pressure that effectively acts in the corresponding working chamber. If one of the pipelines 15-18 and one of the pa6o4i; ix chambers 9-14 are loaded with pressure, then all the distribution pistons to the right of the pressure-loaded working chamber move to the right.
    The last distribution piston 6 acts on the plunger 20, the end of which 21 interacts with the valve body or with the ball 22 of the hydraulic valve 23. When mixing 09039
    The piston 6 to the right is pushed by the piston 6 to the right, the ball 22 rises and the flow medium flows through the connection 24 and enters the annular chamber 25
    5 and further in the connection 26 of the pipeline. Connection 26 pipe (not shown) is connected to the connection 27 leading to the working chamber 28 of the hydraulic piston 29,
    10 mounted in the cylinder 30, the hydraulic piston, through the rod 31, actuates the head 32 of the water shut-off valve 33, which is raised. As a result, water from
    15, the inlet 34 flows through the valve 33 and the outlet 35. Before the inlet connection-; or behind it, a stop valve (not shown) is installed, which opens from 20 when the rotary motion of the notch head is activated. Only when both valves open, the water supply to the nick head is turned on. If none of the working chambers
    25 9-14 is not loaded with pressure, i.e. the water supply to the notch head should be blocked, then by the spring 8 all the pistons are pressed to the left to the initial position. To ensure the return of the hydraulic piston 29, the pressure medium must leave the working chamber 28. The pusher 20 has an axial drilling 26, a sealing guide 37, a chamber in which
    50
    The propeller pusher5 is partitioned into
    the chamber 25 adjacent to the valve 23 of the pressure medium and the chamber 38 remote from the valve 23. Axial drilling 36 of the pusher 20 is connected through circular, 39 drilling to the chamber 38
    coming out - butt 21 pusher 20. When crushing butt 21 pusher onto ball 22, the latter closes the mouth of drilling 36 at the end 21, as a result of which the pressure medium can enter the working chamber 28 only through connection 26. When the pusher 20 moves back, the mouth at the end 21 opens and the pressure medium flows out of the working chamber 28 through the connections 27 and 26 and enters through axial drilling 36 into the chamber 38 and further through the connection 40 into the pressure medium reservoir
    55 Water supply to the notch head begins only with simultaneous activation of the rotational movement of the notch head (not shown) and
    312090394
    at least one second worker to the right, movement of the notch bar of the mode, for example, movement of the notch up, movement of the notch bar downward to the left, movement of the notch bar or forward movement of the machine.
