    FIELD OF THE INVENTION The present invention relates to the mining industry, in particular to boring heads for a rotary percussion, impact or rotary aggregate.
    The purpose of the invention is to increase the service life of the drill head by compensating for the radial beating of the rod.
    FIG. I shows a drill head, a cut; in fig. 2 shows an example of the arrangement of the support sleeve and the inner sleeve; in fig. 3 illustrates an example of performing the fixing of a flushing head to the body of a boring head; in fig. 4 - supporting sleeve, top view.
    The casing 3 of the drill head is fastened to the body of the drilling unit 1 by means of a threaded joint 2. The tool 4 is fixed in the housing 3 by means of a fixing part, in this case an insertion element. The insertion element 4 has blades 5, which serve to transfer torque from the drilling unit to the insertion element.
    The plug-in element is threadedly connected to the drill rod and has a longitudinal notch 6, made in the form of a blind hole, into which the radial hole 7 goes. The latter, in turn, goes into the annular cavity 8, which is formed by the flushing head 9 and the insert element. Flush head 9 contains inner cup 10

    which is sealed with respect to the insert member by means of sealing rings 11 and 12 of circular cross section. The inner cup 10 has drills 13, which extend into the annular cavity 14 of the sleeve 15. The annular cavity 14 is sealed to the inner cup 10 by means of seals 16 and 17. The sleeve 15 has a threaded connection 18 into which a threaded nipple can be inserted to connect the flushing hose . The clutch 15 is fixed with a nut 19 and its position near the inner cup 10 and pressed against the annular groove 20 of the cup 10. The nut has a stop thread for fixing the clutch 15. The inner cup 10 has an end face 21 on its end, which interacts with the end thrust surface 22 of the support sleeve 23. The end thrust surface 22 is pushed against the end thrust surface 21 of the inner cup with the help of cup springs 24. With the help of the stop member 25 fixed on the body thread means, the washing head is limited in its axial podvizhnosti.Uporny retainer member 25 has a threaded joint in the form of pins 26 that engage in the grooves 27 of the inner cup 10, whereby the latter is fixed against rotation. Support sleeve 23 has (figure 4) grooves 28. Tortsova thrust over
    The interior of the inner cup 1, 21, has an annular portion 21a, which extends normally to the axis a of the insertion element and without rupture passes into the cone-shaped portion 21b. The support sleeve 23 has only one annular end thrust surface 22 that is normal to the axis a. If the axis of the insert element (tool) is identical to the geometric axis of the insert element (tool), respectively, the flat ring-shaped parts of the end stop surfaces 21 and 22, respectively, interact whether rotational or shock movement of the tool is made. Surfaces are pressed against one another by cup springs 24, through which very high surface pressures can be created. If the real axis does not coincide with the geometrical axis of the insertion tool and as a result, the insertion tool performs a swinging movement, in particular a precision movement, then the conical surface 21 of the inner cup 10 in rotational or shock motion comes in contact partly with another end stop surface 21 of the support sleeve 23 Thus, with this design, an exact fixation of the flushing head with respect to the housing is achieved, while maintaining limited mobility, since the gift of which no proper movements, vibrations, are allowed.
    In an embodiment of the device (Fig. 2), the dish-shaped threads 24 act on the end 29 of the inner cup 10, while they rest on the stop element 30 and thus press the end stop surface 21 to the support sleeve 31, which is mounted on the housing 3 in the recess 32 .. Support sleeve 31 is executed on from hardened material. Particularly clearly in FIG. 2 shows the separation of the end stop surface 21 into an annular part 21a and a cone-shaped part 21b.
    In the embodiment of the device (FIG. 3), the flushing head of the cup springs 24 is pressed against the support sleeve 33. The latter is held by means of bolts 34 and nut 35 on the housing 3.

    The support body Jca 33 has spherically curved thrust surfaces 36 and 37, which also ensures a reliable fixation of the flushing head.
    The drill head works as follows.
    During the drilling process, a flushing agent is supplied to the bottom. The annular cavity of the coupling 15 is connected by means of a screwed nipple to a hose supplied with a flushing agent, which through drills 13 and further through the annular cavity 8 formed by the flushing head 9 and inserted with a tool, moves into the radial hole 7 and into the longitudinal hollow 6, after which the flushing agent hits the face. The clutch 15 is fixed in the inner cup with the nut 19.
    To compensate for the radial beating of the rod, the inner cup 10 has an end thrust surface 21 that interacts with the end thrust surface 22 of the support sleeve 23 by means of springs 24. In the direction of the drill head body 3, the axial mobility of the inner sleeve 10 is limited by a stop element 25 associated with the housing. This design allows the flushing head to repeat the precise movements of the insertion tool together with it, with this position of the insertion tool relative to the body is so regulated that the boring head does not make any additional movements.
