    A tool for a mineral winning machine, more usually a plough, has a flat plate-like body with a bore containing a nozzle insert and preferably a hard metal cutting region or blade is also provided on the body. High pressure water is conveyed through the bore and nozzle insert to discharge as a jet which is directed to impinge against the mineral or coal face to effect a cut therein hydraulically. The nozzle insert has its discharge mouth in a protected position inside the body.

    2. The tool of claim 1, wherein the connecting element is in the form of a flange.
    3. Instrument according to claims 1 and 2, in which the rod is provided with a cartridge in which the nozzle is installed.
    one
    4. A tool according to claims 1 to 3, in which it is made that the channel is made facing the cutting face.
    The invention relates to the mining industry, namely to a cutting tool for mining machines. Cutting tools for mining machines are known, including a housing and a cutting head with cutting edges, having supply channels 13.
    The disadvantage of such tools is that the supply fluid is intended only for dust suppression, which reduces the efficiency of the cutting process.
    Closest to the present invention is a cutting tool for mining machines, comprising a housing and a working head with a cutting face, having a water passage, in which a high-pressure nozzle is installed, located at a distance from the cutting face 2.
    The disadvantage of such a tool is the difficulty of mounting the nozzle, which reduces the reliability of the device as a whole.
    The purpose of the invention is to increase the effect
    tivrezreza-sh, increase in term
    service and ease of installation tool.
    .
    The goal is achieved by the fact that in a cutting tool for mining machines, including a housing and a working head with a cutting face, having a water passage, in which a high-pressure nozzle is installed, located at a distance from the cutting face, the working head is equipped with a rod located in the channel , at the same time at one end of the rod is located the nozzle, and the other end is equipped with a connecting element.
    The connecting element is designed as a flange.
    The rod is equipped with a cartridge in which the nozzle is installed.
    The channel is made on the cutting edge.
    FIG. 1 shows the proposed cutting tool, in which the nozzle is located in the working head, a general view; in fig. 2 - the same, at which the nozzle is located at the rear of the housing; in FIG. 3, the filling agency of the plow with the proposed cutting-edge tool, obiy type; in fig. 4 - cutting tool at the time of his work.
    The cutting tool (Fig. 1) includes a body 1 and a working head 2 with a cutting face 3. The working head is provided with a hollow rod 4, which is located in the water supply channel 5, which is made inside the working head with its exit to the cutting face. At one end of the hollow rod | there is a high-pressure nozzle 6 installed at a distance from the cutting face. the other end of the hollow shank rod | n a connecting element made, for example, in the form of a flange 7. The hollow rod is provided with a cartridge 8, in which the nozzle is installed, and secured in the workpiece, for example, by means of a threaded connection. The diameter of the rod is larger than the diameter of the supply channel that goes to the cutting face. The high pressure nozzle can be located perpendicular to the cutting surface. In this case, the outlet channel has a conical expansion 9, which is 2 - 10 times larger than the diameter of the channel. On the executive body of the plow, the cutters with nozzles 10 can alternate with conventional cutters 11 (Fig. 3).
    When the tool is in operation, a high-pressure water jet (Fig. 4) flows out onto the bottom 12 obliquely, and in front of the cutting tool a loosened gap is formed, into which the cutting tool enters.
    When the nozzle is perpendicular to the cutting surface; (FIG. 2), a high-pressure water jet produces a cutting slit in the bottom.
    located at a distance from the cutting face of the tool, which makes it possible to loosen the bottomhole zone.
    The proposed device allows reducing the wear of the cutting part of the tool.
