    The invention relates to the mining industry, namely to devices for cooling the cutter with a vrubdawa machine.
     The purpose of the invention is to reduce the water consumption during operation of the cooling device, the cutter of the cutting machine.
    FIG. 1 shows a device for cooling the cutter of the cutting machine through the cutter holder and through the valve along the axis of the cutter and the valve; 2 is a view A of FIG. one.
    The apparatus for cooling the cutting machine cutter includes a cutter 1 mounted in bearings in the cutter holder 2 with the possibility of axial displacement a distance a. The number 3 denotes the surface of the tool holder, on which the latter is welded to the cutting head of the ironman. On the cutter 1 in the direction of the arrow 4 through the spring 5 acts force vfubki. The spring 5 interacts with the conical valve 6 of the shut-off valve 7, and the connecting element 9 is connected with the rod 8 of the conical valve 6, which presses the shank 10 of the cutter 1. The spring 5 can be made in the form of a helical spring connected to the conical valve 6 and located coaxially with it.
    The pressurized water is supplied to the space 11 in front of the conical valve 6 through the holes 12 through channels (not shown) in the cutting head and in the holder of the clove and acts on the conical valve 6 in the locking direction, i.e. in the same direction as spring 5. The force acting through element 9 on cutter 1 towards the cutting force acting in the direction of arrow 4 is made up of spring force 5 and force due to water pressure, and the sum of these efforts should be large in magnitude, that the cutter only with uniaxial cubic compressive strength of the rock to be cut down, at least 20 N / mm, overcomes this force and, therefore, lifts the conical valve 6 from its seat, while the return force
    is at least 3 kN.
    I
    A piston 14 is connected to a conical valve 6 by means of an external thread 13, which is mounted in a cylinder 15 with a seal. A space 16 is formed between the conical valve 6 and the piston 14 by means of an annular recess, into which the water outlets 17 fall. With a conical valve 6, lifted from the seat 18, water under pressure flows from the space 11 into the space 16, from here through the outlets 17 through the grooves in the external thread 19 through which the cylinder 15 is installed in the cutter holder, and through the gap 20 between the cylinder 15 and a drilled hole in the cutter holder - to the space 21 in front of the nozzle 22, from which it is narrowly jetted 23 is injected to the chest, the bottom in the area of the cutter 1. The water pressure in the space 21 is relatively high and is, for example, 200 bar. formed narrow with labor 23.
    When the valve is closed, i.e. when the cone valve 6 sits in the valve seat 18, the water pressure in the space 12 acts on the annular surface, the value of which corresponds to the cross section b of the outer edge of the valve seat 18 minus the cross section from the valve stem 8. As soon as this force is due to water pressure on
    The spring support 5 is formed from resilient discs 30 and 31 that can be screwed into valve body 32. If this elastic disk is screwed further into the valve body, then the springs

    The conical valve 6, together with the force g, is tightened more strongly and the return spring 5 will be overcome by the cutting force acting in the direction of the arrow 4, the valve will open.
    As soon as the cone valve 6 rises from the valve seat 18, space 16 creates water pressure, which, with the exception of hydraulic losses, corresponds to the pressure in space 11. Water pressure acts when the valve is open on the annular surface d, the value of which corresponds to the cross section e of the piston 14 minus the cross section of the valve stem 8. Since the cross section of the valve stem 8 is smaller than the cross section e of the piston 14, this force acts in the direction of closing the valve. The return force acts when the taper valve 6 is raised in the direction of closing the valve and opposite to the punching force acting in the direction of the arrow 4, therefore consisting of the force of the spring 5 and the pressure of water acting on the annular surface d. Since the annular surface d is smaller than the cross section b of the outer edge 24 of the valve seat 18 minus the cross section C of the valve stem 8, the return force due to the water pressure is less when the valve is open than with the valve closed. Therefore, the cutting force the cutter, in which the valve 7 is open, is greater than the cutting force of the cutter, in which the valve 7 is closed, and thereby prevents the vibrations of the valve 7, and consequently, the vibration of the cutter 1,
    the effort gets bigger. The valve plate 30 (31) can be locked in the appropriate position with the help of locknut 33. In this way, the return level can be adjusted.
