The device is also equipped with a programmable control unit 4 his work and the major nodes disclosed the filing of the device to the bottom and organization of the upward flow of the drilling mud.

The device is also provided with a means to control the position of its body with sinking output, mounted on shafts 7 with adjustable supports 8 and the supports 9 (Fig. 1, 7). This control has several nodes, one of which is an aerodynamic device as a console mounted on these supports console flaps 10; other aerodynamic device made in the form of monocryl 11 streamlined aerodynamic shape, fixed to the housing by means of ball bearings 12 and having an actuator 13 of its orientation - selection of the angle of attack. One surface of monocryl 11 and one surface of the cantilever flaps 10 (mostly the top, in Fig. 1, 6, 7) is made convex curvilinear, and the other surface of monocryl and flaps made or concave or straight; these surfaces are respectively 14 and 15, 16 and 17.

The device has an additional generator 18 of the working fluid with its nozzles 19 oriented in the direction opposite from the bottom, and designed to enhance the upward flow of drill cuttings and create additional efforts of the supply device to the slaughter.

Node tracking the position of the body made in the form of curved pipes is when equipping their cavities movable bodies 22, having or positive buoyancy (Fig. 2), or negative buoyancy (Fig. 3). The ends of these tubes fixed 23 pairs of conductive contact pins, when this tube is made of non-conducting material.

Paired contact pin 23 connected by communication with the control unit 4 by the operation of the device. The body 22 (Fig. 4, 5) made of material 24 having a positive or negative buoyancy for the tubes, respectively, Fig. 2 and Fig. 3, with the body covered with a conductive sheath 25 and have a through hole 26 for free flowing liquids moving in its environment in the cavities of the tubes 21.

The device on his body has a support rollers 27 (Fig. 1) to enable its local move, for example, during loading and local transportation; these rollers may be spring-loaded and clean the grooves of the device.

Orientation position monocryl relative to the housing is effected by means of a reciprocating actuator 28 (Fig. 6), the stem of which regulate the position of the wing and the position of the device. The flaps 10 are adjusted by means of drive rod 29 (Fig. 7) connected to the actuator unit 4 is and which is fixed to the flap 10.

The operation of the device is as follows. The device with its housing 1, and a working body 2 is placed in the mouth of development and from block 4 serves the command to start the generator 3 of the working fluid, which, escaping under pressure from the nozzles 5 and 6, carries out the destruction of the rocks on the bottom and the removal of drill cuttings to the mouth of the excavation. This set the direction of the drilling stand, including aerodynamic devices 10 and 11, the position of monocryl 10 along the body 1 and the modification thereby of the angle of his attack to the incident flow of the sludge is carried out using a piston actuator 28, and regulating the position of the cantilever flaps along the body and changing thereby the angle of attack of their relative wind sludge are using the drive rod 29 by turning the flaps at a given angle. Thus, if the horizontal direction of penetration, the position of the bodies 22 in the tube 21 is kept in the middle part of the tube (Fig. 2 and 3), and if necessary, change the direction of penetration change the angle of attack position along the body 1 monocryl 11 and the surfaces 14 and 15, and also the position of the cantilever flaps 10 and its surfaces 16 and 17, forcing it to move the body 22 in the tubes 21 and snap a PA the Finance provisions of the housing 1 in the formulation in a given direction, and if necessary, return the case again in the horizontal position, turn off the power supply pair 23 and rotation of the flaps 10 return the body to a horizontal position, and the body in the center of the tubes.

If necessary, rotate the device to the left (Fig. 9) flaps 10 with the left hand turn down, but the opposite - up when turning the body to the right (Fig. 10) to produce reverse rotation of the flaps. When changing the direction of drilling up by turning the flaps 10 down; and when the direction of drilling at an angle down the flaps 10 turn up, using monocryl to increase efforts or lifting body or its tilt down.

The placement of these aerodynamic devices on the device is not a technical difficulties, because the sizes of these devices agree on the place with the dimensions of the device, these devices can be made modular.

Thus, the developed device allows mobile to carry out the choice of directions sinking output, changing these directions, using all technical equipment this device.
