The invention relates to tunnel complexes, and in particular to systems for working driving increased width and height of the semicircular cross-section, and can be used for drilling openings in homogeneous rocks, for example, the Cambrian clays, the excavation excavations during the construction of metro stations or facilities for other purposes.

Famous adopted for the prototype system for drilling openings containing placed on supplied with the drive movement of the frame mechanisms of rock failure in six disk cutters, two internal and six external, bucket handling device and conveyor system for loading of the rock mass in the vehicle (Pokrovsky mathematical SCIENCES. Construction and reconstruction of mines, part 3, vol. 5, M, G n-t publishing house on mining, 1963, p.260-262, RIS).

However, the drawback is the impossibility of its use for working driving enlarged cross-sectional semicircular shape.

The technical result of the invention is the provision of opportunities for working driving enlarged cross-sectional semicircular shape.

The complex is presented in figure 1 - location of the elements in their original position, figure 2 - section a-a of figure 1, figure 3 - a view B of figure 1, figure 4 is a view of figure 1.

The complex consists of a frame with a drive mechanism of movement (not shown). On the frame is rigidly fixed placed coaxially with each other at the base of the 1 generation two fixed relative to the frame horizontal troughs 2 and 3 with the drive screws 4 and 5. Over one of the grooves 2 with screw 4 in the initial position, an additional groove 6 with a drive screw 7 with the possibility of rotation in the vertical plane relative to the pivot point 8, secured to the frame in its middle part in the width of the output, using the actuator 9 with the toothed wheel 10 with vzaimodeystviya fixed to the frame of the rack 11 of the circular profile with a radius r relative to the axis of the pivot point 8. In the Central part of the generation between the end edges of the stationary chutes 2 and 3 and under hinge node 8 is placed associated with the actuator 12 is properly oriented relative to the bottom 13 of the horizontal shaft 14 with screw blades 15 and 16 mounted thereon, respectively, outside of the screws 4, 5 and 7 from the side of the face and on the opposite side, where the helical blade 16 is placed in the groove 17 adjacent to the stationary chutes 2 and 3. On the outer edges of all of the screws 4, 5, 7, and screw on the blade end 15 of the shaft 14 facing the bottom, fixed cutting elements. Fixed 2, 3 and the pivot 6 of the gutter placed with a gap relative to the screws 4, 5 and 7 and with the possibility of some overlap in the height of the side opposite to the surface of the bottom 13 passable development by placing the lower edges of the grooves at the lower edges of the augers. The upper edge of the stationary chutes 2 and 3 is made with bent away from the bottom 13 parts 18. The sleeve 19 of the shafts of the screws 4, 5 and the sleeve 20 of the shaft of the screw 7 with transverse beams attached to their trenches 2, 3 and 6. The shaft of each screw by means of a chain kinematically associated with installed on the outside of the gutters actuators 21, 22 and 23. The shaft 14 is placed in the sleeves 24 and 25, and the diameter D0the helical blades of the shaft 14, is placed between the end edges of the stationary chutes 2 and 3, is equal to the double d is ametro D their screws 4 and 5. 26 and 27 to the rotation direction of the trench 6 with screw 7, 28 - curved profile with a radius R passable output.

The complex operates as follows. Frame 1 mounted on it equipment with a drive movement is placed at the bottom 13 of manufacture. Included drives 21, 22, 23 of the screws 4, 5, 7 and the actuator 12 of the shaft 14. The frame is shifted in the direction of the bottom 13. Due to this, the first beginning with the rotary shaft 14 with a screw blade 15 with the cutting elements on their face part is removing rocks from the middle part of a cross-country output, and then screws 4, 5 and 7 are embedded in the bottom half of the diameter of the screw blades with the movement of destroyed rock in trenches 2, 3 and 6 in the direction of the shaft 14 and further movement of rocks along a groove 17 and the overloading of vehicles. After that, turn the actuator 9, providing turn chute 6 screw 7 relative to the pivot point 8 in the direction of 26 due to the engagement of the toothed wheel 10 with the rack 11. When turning the chute 6 with screw 7 (in figure 1 the dashed line shows its intermediate position) the main part of destroying them breed comes first in the chute 2, and after turning 90 degrees - in trench 3, the screws 4 and 5 which breed is reloaded into the chute 17. The remainder of the breed the chute 6 is transported directly into the chute 17 through which the screw blades 15 and 16 is reloaded into the vehicle. After turning chute 6 with screw 7 180 degrees the frame is again shifted in the direction of the face 13 with the implementation of the screws 4, 5 and 7 on half of their diameter. Then again turns on the drive motor 9 with its reverse, allowing the chute 6 with screw 7 is rotated relative to the pivot point 8 in the reverse direction 27 again 180 degrees with the destruction of species around the radius R. the following cycles are repeated until complete penetration generate desired length. Interaction describes the equipment ensures the destruction of the breed passable production over the entire area of its cross section. The implementation of the troughs 2 and 3 with convex parts 18 eliminates the possibility of spilling destroyed by a screw 7 of the breed outside of the troughs 2 and 3.
