The invention relates to mining equipment and can be used for carrying out excavations in underground mining.

Known continuous miner, which includes drilling an Executive body, bemovie cutters, cutting drums, which separates the shield from four sections with attached flanges and cuffs, which are the conveyor, hydraulic system with oil station and control panel and the seat of the driver [1].

The disadvantage of this harvester is that when carrying out excavations in the destruction of the mountain massif of the Executive bodies produce large quantities of dust, which penetrates through the opening above the conveyor between the shield to the workplace of the driver, worsening the conditions of his work, threatening the acquisition of occupational diseases.

The objective of the invention is to reduce the dustiness of the workplace of the operator during operation of the harvester.

The technical result is achieved by the fact that the harvester shaft sinking, including tracked undercarriage, drilling Executive body, bemovie cutters, cutting drums, which separates the shield from four sections with attached flanges and cuffs, the conveyor sides in the shape of a tray, remote control hydraulic system, control station, elektrooborudovanie the m harvester and the seat of the driver, further comprises two paleoparadoxia valve mounted pivotally through the veils on having a grooved shape the sides of the conveyor at an angle to the vertical, while paleoparadoxia flap is made from the driver's seat with locking mechanism that holds the levers arranged to move in one direction only to the stops installed on one of the flaps, freeing the adjacent flap.

1 shows a harvester shaft sinking, figure 2 - between the shield combine with paleographie dampers, figure 3 - their side view.

Harvester mine tunnel includes crawler undercarriage 1, the drill Executive body 2, bemovie cutter 3, the cutting reel 4, which separates the shield 5, the conveyor 6 with the sides having the shape of a trench 7, 8 remote control of the hydraulic system of the harvester, station 9 management of its equipment, the seat of the driver 10.

Between the shield 5 is located on the harvester in such a way that provides a barrier all the bottomhole space with dust-raising cutting bodies 2, 3, 4 from the rest of the exhaust space. It consists of four sections 11, 12, 13, 14 with attached flanges 15, 16, 17, 18 with sleeves 19 of the conveyor belt. To the sides 7 of the conveyor 6 having a grooved shape, pivotally attached to the curtain 20 two pylori the surrounding flaps 21 and 22 at an angle to the vertical. Paleoparadoxia flaps 21 and 22 from the driver's seat 10 is equipped with a locking mechanism. He performed on each flap 21 and 22 in the form of a rigidly attached sleeves 23. The sleeve 23 of the valve 21 are aligned (in the horizontal plane) of the hubs 23 of the valve 22, forming a pair. Into the holes of the pairs of bushings 23 dampers 21 and 22 inserted levers 24 with pull-out from the sleeves 23. On one of the flaps opposite the bushing 23, but at some distance from them, are the stops 25. One end of each of the levers 24 is bent so that the lever can be nominated only in one direction until it stops 25, releasing the sleeve 23 adjacent flaps. After the flaps 21 and 22 are able to rotate on the bolts 20. Flaps on the outer contour have attached the cuff 26 of the conveyor belt.

Harvester shaft sinking works as follows.

Drilling the Executive body 2 in the mountain bounces ore, forming a niche cylindrical section. Feed is working movement of the harvester on the bottom crawler undercarriage bogies 1. Bemovie cutters 3 beat ore near the soil, changing the cylindrical section of the arch. The remaining jumpers are removed cutting reel 4. These operations are managed by the operator from the remote control 8 control hydraulic system of the harvester and station 9 management of its equipment, with the Dublin core on the seat for the driver 10.

When all cutting processes in air produce large quantities of dust, worsening working conditions and threatening the health of the operator of the harvester.

For enclosing the space where the seat of the driver 10, the dust on the harvester is mounted between the shield 5. Shield 5 consists of four fixed sections 11,12, 13, 14 with attached flanges 15, 16, 17, 18 with sleeves 19 of the conveyor belt. To the sides 7 of the conveyor 6 having the shape of a trench, pivotally attached to the curtain 20 two paleoparadoxia flaps 21 and 22 at an angle to the vertical so that they are positioned above the conveyor 6, leaving only space for the posting of broken ore transported.

Before cutting processes of the mountain massif of the flaps 21 and 22 are closed. To do this, turn both valves to align the holes of the sleeves 23 on clearance and push them in the levers 24 to lock their bent ends to the edges of the sleeves 23 of the valve 21. Cuff 19 and 26 of the conveyor belt that are attached on the contour enclosing shield 5 and both valves 21 and 22, comparative tightness of the bottom space and greatly reduce the penetration of dust out in the area of the workplace to the operator of the harvester.

For collection of the harvester from the goaf, you need access to the Executive body. To do this, push the levers 24 of the bushing 23 of the valve 21 and 2 to 25 stops on the valve 21, completely freeing the sleeve 23 of the valve 22, and open them yourself.

When re-cutting processes pre-closing valves 21 and 22 and push the levers 24 in the holes of the bushings 23 dampers. As there are lugs 25, limiting the extension of the levers 24 of both of the sleeves 23, the latter serve as guides for these levers 24 and, since the sleeve 23 in pairs coaxially, the levers 24 are easily pushed. Flaps 21 and 22 are closed. The blasting array of arched cross-section can be produced. Because all of the bead 15, 16, 17, 18 sections 11, 12, 13, 14 and the flaps 21 and 22 on the contour have attached the cuff 26 of the conveyor belt, is provided comparative tightness of the fence dusty areas.

With this design combine to significantly improve the working conditions of the operator of the harvester shaft sinking and access to cutting bodies harvester is not disturbed.
