The invention relates to mining.

A drilling tool is known for the extraction of a mold, in which the spreading is load-carrying, x: r.u-cTCH:: 1) it grows with a core. 1. The disadvantage of this tool is n:: the complexity is unr: and lenn.

The Mainbucking auger is known, containing parallelly located drilling rigs with deviating 1nneks, a drilling carriage, mounted on the frame, rods, and interacting with the rejects of the X -necks and remote control 2.

The purpose of the invention is innovation and efficiency and reliability of pv / - control; 1CMI nshekami.

This is achieved by the fact that the remote control m.chapism is carried out in the form of a traverse and a strengthened internal carriage of a power hydraulic cylinder with a two-current piston, one HJTOK of which is connected to a rod of rods, and the other with a traverse, inside which are marked out pggans with an installation. spacer between them. at this m. haystacks (ntang equipped with .and ;,

interacting with rakes fixed on the frame.

K | 1 | Moreover, the spacer element is made of a centerpiece and hydraulic cylinder, the stem of which is; - ;; connected to the cam through the lever. N. fpg 1 shows the proposed map.1, plan: in FIG. 2 - 1ppekoburov. The machine is fixed upward; in fig. 3 dan knot I on fpg. one.

The auger machine contains parallel drilling rigs 1 and 2. Between which a rod 3 is installed, which interacts with a device for deflecting rezhnyi nzhek 4, connected by cardan 5 with drill rigs, which

are equipped with lanterns 6. A device for deflecting dir} w; their P1neks 4 are made, for example, in the form of a prism 7 (see Fig. 3) with steps 8 interacting with the support roller 9 of the apron 10, 1 which is connected to go, with a ground lamp 6. The drill carriage 11 is fitted on the frame 12 and is equipped with a feed drive, imprinted in the form of drums 13, enveloping ties 14, the ends of which are fixed on the frame 12. The remote control mechanism of the cutting screws 4 is designed as reinforced inside the carriage 11 of the hydraulic cylinder 15 with a double-rod piston, the rod 16 of which is connected with the rod 3, and the rod 17 - with a cross-beam 18. Inside the cross-beam are placed spring-loaded rods 19, at the ends of which the crests 20 are reinforced, interacting with 12 rails 21 fixed on the frame 21. Between the spring-loaded rods 19 there is a spacer element made, for example, in the form an eccentric 22 connected via a lever 23 to a rod 24 of a hydraulic cylinder 25 fortified on a traverse 18. The latter is provided with a sleeve 26 on which a rail 27 is fastened, interacting with a ridge 28 fixed on the rod 29 mounted on a carriage 11 of a hydraulic cylinder 30. W nekoburov machine works as follows. When the well depth is reached, the eccentric 22 pivots the spring-loaded rods 19 until the ridges 20 interact with the rails 21. The carriage 11 is driven back with the simultaneous rotation of the drill stands 1 and 2. As a result, the prism 7 is braked in the wells, the roller 9 rolls into steps 8 and deflects an apron ID at an angle along with cutting screws 4. The lifting height of cutting screws 4 is controlled by the amount of "movement of a hundred BOB 1 and 2 back. After that, the rod 19 unloads and fixes the position of the carriage 11 relative to the crosspiece 18, for which, with the help of the hydraulic cylinder 30, the ridges 28 are pressed against the rails 27. The carriage 11 is fed from the bottom while rotating the cutting screws 4, which destroy the upper mineral pack. Under. By the action of gravity and blades of the cutting jaws 4, the mineral is moved to rotating drilling rigs 1 and 2, which transport it to the wellheads. In the event of a roof collapse, the hydraulic cylinder 1-5 is turned on and the prism 7 is moved to the wellhead. The roller 9 rolls down the steps of the prism 7, and the cutting jaws 4 descend. The drill rigs 1 and 2 are removed from the well for a distance that ensures the safety of work, and the cycle of operations to raise the cutting jaws 4 and destroy the mineral pack at the roof is repeated. Claims 1. An auger machine comprising parallelly mounted drilling rigs with deviating cutting screws, a drilling carriage mounted on a frame, becoming rods, interacting with a device for deflecting cutting screws and a remote control mechanism that is different in order to increase efficiency and reliability of cutting screws control, the remote control mechanism is made in the form of a cross member and a fortified hydraulic cylinder with a two-rod piston mounted inside the carriage, one rod of which It is connected with a rod set and, on the other hand, with a crossbeam, within which rods with spacers installed between them are placed, with the ends of the rods fitted with crests, which interact with the rails attached to the frame. 2. The machine according to claim 1, wherein the spacer element is made of an eccentric and a hydraulic cylinder, the stem of which is connected to the eccentric via a lever.
