The invention relates to mining equipment, and more specifically to a downhole scraper conveyors, and is intended for use in places of displacement of the transported material with sabinescovici conveyor, containing unloading a plow mounted at an angle to the direction of traffic of coal on the conveyor for side unloading large pieces and parts of the coal, who was above the scraper chain, and openings in the bottom of the pan and the frame for discharging remaining on the conveyor fine coal (patent Germany N 1936319, CL E 21 D 13/06, publ. 1976).

The disadvantage of this device is that the device, when deciding circuit protection and unloading shares from damage, does not exclude the formation of jams and wakefulness coal on the roadway. This is because large pieces of coal, moving in the transverse regarding traffic direction is small, located between the scrapers coal, when the lateral unloading lose speed and meet more resistance, which leads to traffic congestion and coal spillage on the roadway.

Closest to the present invention is a device for unloading scraper conveyor containing placed at an angle to the direction of movement of the scraper and scraper over a chain of handling and shingles supplied is placed above the scraper chain sheet before forming a fixed blade horizontal space. Ploughshare is connected to the sheet by means of Rethimno, the discharge of coal from the conveyor above the scraper chain, as part of small coal, which is at the level of the scraper chain, passes under the discharge plowshare motor cylinder, or "picked up" scrapers lower branch of the chain conveyor, which can lead to zastarovje guides the chain conveyor, the increase of the power consumption on the drives and in the extreme case of a chain breakage.

The problem to which the invention is directed, is to reduce the spilling of coal on the roadway, except tastybaby branches of the scraper chain, reducing the complexity of the execution of limit operations.

The invention consists in that the device for the lateral discharge scraper conveyor contains placed at an angle to the direction of movement of the scraper and above the scraper chain unloading share with the horizontal platform and the window between the discharge space and a medium sheet pan. The device has placed at an angle to a horizontal platform overlying the window between the discharge space and a medium sheet pan spring-loaded valves with the possibility of installing them in a horizontal position during movement of the scraper according to one of them through mechanical swazo face conveyor side window covers made of rectangular slits.

Open manholes are spaced from each other along the length of the pan.

In Fig. 1 shows a device for the lateral discharge scraper conveyor; Fig. 2 section a-a in Fig. 1; Fig. 3 the position of the damper mechanism side discharge until the passage of the scraper face of the conveyor; Fig. 4 - position of the vanes during the passage of the scraper face conveyor.

The device consists of a plow blade 1 mounted above the upper branch of the scraper chain 2 at an angle to the direction of movement of the traction unit conveyor; pan 3; spring-loaded valves 4, 5, disposed at angles to the horizontal platform 6, mounted on shafts 7, 8 (Fig. 3) and connected by an adjustable length rod 9 fixed to the shoulders 10, 11, and the shoulder 11 is connected to the absorber 12, the window covers 13, 14 done in the guides of the branches of the chain drag conveyor 15 rectangular slits 16 for discharging fine coal gate on the reloader 17. Pulling the body of the conveyor chain equipped with scrapers 18, and between the discharge space and a medium sheet pan has a window 19.

When the conveyor coal over the scraper chain inertial force and under the pressure of traffic created by the scraper 18, is pushed out by the time of the passage of the scraper 18 to the valve 5, it is lowered into a horizontal position, this automatically through a mechanical connection drops flap 4 and the scraper 18 passes under the horizontal platform 6, while the remaining coal from the rubble of coal transported by the chain links 2 and through the open hatches 13, 14 with the work done in them on the sides of the rectangular slits 16 hits the material handler.

If necessary reverse the chain scraper conveyor 18 passes over the flap 4, leading to the horizontal position, thus automatically lowering valve 5 through a mechanical linkage arms 10, 11 and rod 9. The return of the flaps 4, 5 to its original position by means of spring shock absorber 12.

The proposed device can significantly reduce coal spillage on the roadway, provides a more complete unloading of coal at the face conveyor, eliminates tastebook branches of the scraper chain, which reduces the complexity of executing terminal operations and reduces the number of workers cleared the soil drift.

1. A device for the lateral discharge scraper conveyor containing placed at an angle to the direction of movement of the scraper and above the scraper chain unloading share with horizontal space, and the window between the cargo is social space overlying the window between the discharge space and a medium sheet pan spring-loaded valves with the possibility of installing them in a horizontal position during movement of the scraper according to one of them through a mechanical connection and return to its original state after the passage of the scraper.

2. The device under item 1, characterized in that the guides of the branches of the scraper chain face conveyor side window covers made of rectangular slits.

3. The device under item 1, characterized in that the window covers are spaced from each other along the length of the pan.

Vibrating feeder // 2004476

FIELD: mining industry.

SUBSTANCE: method for extraction and underground use of coal includes cleaning extraction and dumping of coal, fixing and controlling ceiling and transporting coal along face to drift. On the drift, in moveable generator, coal is pulverized for intensive burning with use of jets in water boiler firebox, where high temperature of steam is achieved (about 1400 C), enough for decomposition of water on oxygen and hydrogen. These are separated, then oxygen is fed back to jets, and hydrogen is outputted along pipes and hoses in drifts and shaft. Variants of underground generator for realization of this method are provided. Also provided is method for extraction of disturbed coal beds by short faces. It includes extraction and dumping of coal on face conveyor, fixing of ceiling behind combine, moving conveyor line and support sections in direction of cleaning face displacement, control of ceiling with destruction and partial filling. Extraction of coal is performed in short curvilinear faces by long stripes along bed, in straight drive without forwarding drifts, with preservation and reuse of ventilation and conveyor drifts, equipped with mounting manipulator robots, with fixing behind combine by automatically operating support deflectors without unloading and displacing sections in area of coal extraction. Extraction and transporting of coal is performed by fast one-drum combine and curvilinear reloading conveyor, supplying coal to drift conveyor or immediately to underground gas or energy generator placed immediately on drift. Also proposed is face scraper conveyor for realization of said method, wherein pans are made with step along front face profile, greater, than along back one, while forming common line curved towards face with constant curvature. Also proposed is a method for controlling complex for unmanned coal extraction.

EFFECT: higher efficiency, effectiveness, broader functional capabilities.
