The invention is illustrated by drawings, where Fig. 1 shows the Executive body of the mining machine of Fig. 2 - cutting unit with trueorigin device of Fig. 3 - one of the variants of the constructive execution streammessage fixtures.

The Executive body of the mining machine includes a housing 1, which may be, for example, the shape of the body of rotation. The housing 1 may be mounted rotatably on the drive shaft of a drive (not illustrated). On the housing 1 of the Executive body fixed Portorosa tools 2, which can be used cutters, milling cutter or other tool. Scheme of arrangement of rock cutting tools 2 on the housing 1 of the Executive body is determined by the physical and technical characteristics is outinen with the housing 1 by means of detachable or permanent connection. Rock cutting tool 2 is mounted in a holder 3 with the help of the locking device 4. In the housing 1 of the Executive body done channel 5 for supplying irrigating fluid through a distribution mechanism (not shown) hydraulically connected to the source for supplying irrigating fluid under pressure (not shown). In the case of use as irrigation water liquid source for supplying irrigating fluid under pressure may be performed, for example, in the form of a water pump. Output channel 5 for supplying irrigating fluid is placed truepromise device 6 for supplying irrigating fluid to the rock-breaking tool 2 and/or destructible material. Each trueforms device 6 is installed with a possibility of rotation relative to the housing 1 of the Executive body and can be locked in intermediate positions.

Trueforms device 6 may be made in the form of case 7 with a socket 8 for accommodating the nozzle 9. The nozzle 9 is installed in slot 8 of the housing 7 streammessage devices 6 and has a base of 10. Part of the outer surface of the socket 8 in the housing 7 and the part of the outer surface 10 of the nozzle 9 are sphere is a very useful turn. The nozzle 9 is made with the channel 11 to the expiration of the irrigating fluid, which is hydraulically connected with the corresponding channel 5 for supplying irrigating fluid. Input channel 11 for the expiration of the irrigating fluid can be performed in the bore 12 to provide a hydraulic connection of the specified channel 11 to channel 5 for supplying irrigating fluid during rotation of the nozzle 9 relative to the housing 7 streammessage device 6. At the output of the channel 11 to the expiration of the irrigating fluid can be performed counterbore for the insert 13 for forming a jet of irrigation fluid. Trueforms device 6 has a mechanism for fixing the nozzle 9 in intermediate positions as it is rotated. As a mechanism for fixing the nozzle 9 in intermediate positions during its rotation can be used any known design of the stopper mechanism that provides for the fixation of the two parts at their mutual rotation relative to each other.

One of the most preferred options structural embodiment of a mechanism for fixing the nozzle 9 in intermediate positions during its rotation provides performance as installed on the nozzle 9 of the pressure lepinoy surface 18. The push element 14 is mounted on the nozzle 9 with the possibility of axial movement, for example, using a threaded connection, and stopped in intermediate positions. The push element 14 is mounted for engagement with its stop face 15 with the bearing surface 18 of each of the intermediate element 17. Each intermediate element 17 is installed with the possibility of a limited axial movement to transfer axial forces from the pressure element 17 on the spacer elements 16.

Truepromise device 6 can be located on the outer surface of the housing 1 of the Executive body. The housing 7 of each streammessage device 6 may be connected to the housing 1 of the Executive body with the help of detachable or permanent connection. Most preferred is a variant of the construction execution of the Executive body, in which the housing 1 of the Executive body is made with a slot 19 to accommodate the housing 7 of the relevant streammessage device 6. Under this option, the structural embodiment of the device trueforms device in considerably lesser extent exposed to on his food again">

The housing 1 of the Executive body and the housing 7 streammessage device 6 is most preferably interconnected by means of detachable connections such as screw. To prevent leakage of irrigation fluid connection between the body 1 of the Executive body and the housing 7 streammessage device 6 can be installed sealing elements 20, for example, in the form of rubber rings.

The Executive body of the mining machine operates as follows.

When moving the enclosure 1 of the Executive body, for example, when simultaneous rotation around its longitudinal axis of symmetry and the translational movement in the interaction with the destructible material consistently come Portorosa tools 2. In the interaction of the cutting of the rock cutting tool 2 destructible material is destroyed last. As a result of friction rock cutting tool 2 about destructible material is its intense heat and, therefore, to continue normal operation it is necessary to carry out its cooling. In addition, when exposed to the material rock cutting tool 2 is the violation of a certain type of material capable of spontaneous combustion, and, therefore, to continue normal operation it is necessary to carry out dust suppression in the area. From source for supplying irrigating fluid last pipeline (drawing not shown) through the valve is supplied under pressure to the appropriate channel 5 for supplying irrigating fluid. From channel 5 for supplying irrigating fluid, it flows into the channel 11 to the expiration of the irrigating fluid streammessage device 6 and then through the insert 13, which generates a stream of irrigating fluid of a certain shape and certain parameters directly on the most heated part of the rock cutting tool 2 and/or destructible material. When a schema change is the placement of rock cutting tools 2 on the housing 1 of the Executive body or when replacing the rock cutting tool 2 to a new, geometrical parameters (the overhang of the tool) which differ from the geometrical parameters of the replaced rock cutting tool, it turns out that you need to change the direction of the expiration of the jet of irrigation fluid, because the new scheme of arrangement of rock cutting tool 2, or when changing the geometrical parameters of poslednego the stream irrigating fluid. To change the orientation of the longitudinal axis of symmetry of the channel 11 streammessage fixtures 6 release the locking mechanism of the injector 9, moving up the thread executed on the nozzle 9, the push element 14. When moving the pressure element 9 under the force of elasticity of the material from which made the spacer elements 16, is moved in the axial direction of the intermediate elements 17 and the base 10 of the nozzle 9 is rusticyanin. Then in the inserting hole 13 inserting a solid rod (not illustrated), which will show the direction to the expiration of irrigating fluid from the nozzle 9. Turning the base 10 of the nozzle 9 in the socket 8 of the housing 7 streammessage devices 6, Orient the rigid rod, and hence the longitudinal axis of symmetry of the channel 11 to the expiration of the irrigating fluid to the cutting portion of the rock cutting tool 2 and/or destructible material. After the orientation of the nozzle 9 it is fixed in this position. To do this, move the push element 14 on the threaded part of the nozzle 9 in the direction of the channel 5 for supplying irrigating fluid. When the push element 14 to its hard surface 15 acts on the bearing surface 18 of each intermediate element marouda and fixed from rotation base 10 of the nozzle 9 on the walls of the slots 8 of the housing 7 streammessage device 6. It should be noted that, deformed under the action of axial force, the spacer elements 16 overlap the gap between the outer surface 10 of the nozzle and the walls of the slots 8 of the housing 7 streammessage device 6, i.e. function as an additional sealing element. After carrying out the specified operation with trueorigin devices 6, which are subject to reorientation, include the source for supplying irrigating fluid under pressure and a supply of irrigating fluid is carried out in the manner described above. Thus the bore 12 provides unobstructed passage of irrigating fluid from channel 5 for supplying irrigating fluid to the channel 11 to the expiration of the working fluid at any position of the base 10 of the nozzle 9 with respect to the slot 8 of the housing 7 streammessage fixtures 6.

If necessary, replace or clean the channel 11 to the expiration of the irrigating fluid housing 7 streammessage device 6 is removed from the slot 19 in the housing 1 of the Executive body with a special tool. To facilitate these operations for the case 7 can be made special notches (not shown) to accommodate the special tool.
