    Zur Verringerung der Gefahr einer Überhitzung beim Schneiden oder Brechen von Gestein mit einer Teilschnittschrämmaschine und zur Erleichterung des Brechens bzw. Schneidens des Materials wird Druckflüssigkeit, beispielsweise Wasser, über einen der abzubauenden Fläche zugewendeten Bereich intermittierend ausgesprüht. Dieser der abzubauenden Fläche zugewendete Bereich wird bei einem Schrämkopf dadurch verwirklicht, dass über einen Zentriwinkelbereich der Rotationsbewegung des Schrämkopfes eine Mehrzahl von radialen Durchbrechungen (18) an eine axiale Bohrung (8) für die Zufuhr der Druckflüssigkeit vorgesehen ist, wobei dieser Zentriwinkelbereich demjenigen Bereich entspricht, welcher der abzubauenden Fläche bzw. der Ortsbrust zugewendet-ist. Mit den radialen Durchbrechungen (18) fluchten bei Umdrehung des Schrämkopfes (1) radiale Kanäle (22) des Schrämkopfes, über welche die Druckflüssigkeit zu den Austrittsöffnungen an der Peripherie des Schrämkopfes (1) geführt ist. Die radialen Durchbrechungen (18) sind hiebei über einen Zentriwinkel von weniger als 180°, vorzugsweise 120-150°, angeordnet, und bei vorgegebener Umdrehungsgeschwindigkeit des Schrämkopfes (1) lassen sich auf diese Weise bevorzugte Spritzfrequenzen zwischen 10 und 20 Hz verwirklichen.

    They exist at a frequency of 10–20 Hz. The irrigation device includes a sleeve 2 with an axial channel 9 for supplying fluid and radial holes 7. The latter are located within a central angle of less than 180, in particular equal to 120-150 °. The distance to the center of the radial holes 7 around the circle is equal to three times the diameter the light of these holes. Pod1
    The invention relates to the mining industry, in particular to methods of irrigating cutting edges and (or) bottom surfaces and devices, for implementing these methods.
    The aim of the invention is to reduce water consumption and increase mining safety.
    Figure 1 shows a device for carrying out the proposed method; figure 2 - section a-Anafig,
    A device for carrying out the method of irrigating the cutting edges and / or the bottom surface of a pressurized liquid, in particular water, using a cutting machine, includes a cutting boom 2 (not shown) connected to the bracket 1, in which an axial channel 3 is made for supplying liquid, connected with a fixedly connected with a cut-off boom a part of the cut-in head and with outlets (not shown) on the circumference of the latter.
    To facilitate proper installation of the sleeve 2, the axial water supply channel 3 enters the sleeve 2 through the sealed adapter 4 (seals are denoted by 5). The sleeve 2 in any position is connected with the bracket 1 by the gear coupling 6 and has radial holes 1. The end part 8 of the cutting head rotates around the sleeve, which is connected to the drive of the cutting head. The sleeve 2 is held in its position by the end plate 9, and this end plate is connected to the end part 8 by screws 10.

    water is produced through the axial channel 3 through the boom bracket 1 and the sleeve 2 to the radial holes 7. When it coincides with one of the holes 7 through the radial channels 11 and 13 and then through the outlet holes in the cutter holders, the liquid irrigates the cutting edges of the cutters or the surface slap 2 s, and 3 z.

    The end portion 8 has substantially radial canals 11 which, through the sealing lip 12, pass into the radial channels 13 and further into the outlet openings of the head. The end part 8 rotating around the sleeve 2 is sealed relative to the sleeve 2 by seals 1A and 15, the seal 15 being held in position against the sleeve 2 by the locking ring 16, the latter fixed on the rotating end part 8 by means of a screw 17. The remaining parts of the iron head, made, for example, from separate discs, can be connected to the rotating end part 8 of the cutting head with the help of a screw 13, and the cutting cut g-ch can be supported on the bracket fixed to the cut-off boom.
    The radial holes 7 are located within a central angle of less than 180 5 in particular, equal to 120-150, while the distance between the centers of the radial holes 7 around the circumference of the sleeve p) is three times the diameter in the light of these holes. In addition, between six and ten radial holes 7 are located within a center angle of less than 180.
    The method of irrigation of the cutting edges and (sh1i) of the bottom surface with the help of the device is carried out as follows. The liquid is supplied at a frequency of 10-20 Hz within the central angle corresponding to the circumferential part of the zrubovy head in which
    cutting edges with a bottom surface, through channel 3 through the boom arm 1 and sleeve 2 to the radial holes 7, then, coinciding with one of the holes 7, along the radial channel 11 through the sealing sleeve 12 and further into the outlet openings of the cutting head, which can be placed in the holders of the cutting teeth. Here the cooling liquid irrigates the cutting edges of the teeth and (or) the bottom surface.
