The present invention relates to vehicles and can be used to move the rock mass in underground conditions, in particular when reloading ore from conveyor to conveyor, located at the same level.

A device for 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 the horizontal platform and the window between the discharge space and a medium sheet pan [P. RF 2083849, CL E 21 F 13/08].

The disadvantage of this device is that it is not adapted for handling the rock mass on conveyor, located at the same level as the discharge conveyor.

Known mobile scraper loader adopted for the prototype, [P. RF 2151091, CL E 21 F 13/08], including sectional panline rods with the working and idle branches scraper drawbar organ, thus panline in the longitudinal direction includes two sections: horizontal - boot and console-directional discharge with the appropriate drive and tension heads.

The disadvantage of this loader is that it has a complex structure and loading it occurs at different levels, as well as its not always possible to use due to the large dimensions, for example when overloaded with lawn the first conveyor to the conveyor, located on the haulage drift.

The technical result of the invention is to remedy these disadvantages, namely the creation of a device of simpler construction, which you can use safely and effectively to overload the rock mass from one conveyor to another, which are at the same level.

The technical result is achieved by the fact that under overload conditions of the rock mass from one conveyor to another, which are at the same level, use the device for handling granular material, containing inclined and horizontal sections with drive placed on the support between the two conveyors, which, according to the invention, placed in the enclosure with Windows located on the sides of the conveyors, and made in the form of a chain with scrapers, covering the rollers and mounted for movement in a pair of trapezoidal guides, and a housing mounted on a support using a hydraulic Jack, and the angle of α lateral sides of the trapezoid choose 35-45°.

This decision will allow us to effectively and safely overload the rock mass from one conveyor to another, which are at the same level.

The invention is illustrated by drawings, where figure 1 shows the device for handling granular material, installed between the two conveyors; figure 2 is a view in which trojstva side; figure 3 is a section along a-A.

In the drawings:

1 - discharge conveyor;

2 - download the conveyor;

3 - body;

4 - bearing;

5 - jacks;

6 is a circuit with scrapers;

7 - actuator;

8 - trapezoidal guides;

9 - pan;

10 - cover;

11 - drive roller;

12 - tension roller;

13 - intermediate rollers;

14 - box;

α - the angle of the lateral sides of the line.

Device for handling bulk material includes a housing 3 that is installed at the place of loading rock mass discharged between 1 and 2 downloadable conveyor on the support 4 with the help of hydraulic jacks 5. In case 3 posted by trapezoidal guides 8, the angle of α lateral sides of the trapezoid choose 35-45°. Along the guides 8 moves the chain with scrapers 6, which covers the drive roller 11, a tension roller 12 and the intermediate roller 13. The drive roller 11 is driven by means of the actuator 7. With the top of the housing 3 is a cover 10 and the bottom case 3 - pallet 9. The tension roller 12 is designed for tensioning or loosening the chain with scrapers 6, and the intermediate rollers 13 are set so that the movement of the chain with scrapers 6 occurred along the guides 8. On the housing 3 is a cover 10, which closes the rotating part of the device. It is necessary to increase the safety of miners. orpus 3 mounted on a support 4 with the help of hydraulic jacks 5, employees for height adjustment device. The proposed device operates as follows. Device for handling bulk material set between the two conveyors, one of which is discharged to 1, and the second (which is the overload of the rock mass) 2 downloadable. When moving rock mass discharged by the conveyor 1 is prosep of rock through the window 14 of the housing 3 on the tray 9. Next, the rock mass is moved inside the housing 3, the movement of the chain with scrapers 6 along the guide rails 8. The sides of the trapezoidal guides 8 are angle α=35-45°this is necessary in order to create a smooth transition of the rock mass at the time of discharge from the discharge conveyor 1 through the window 14 on the tray 9, as well as to create favourable conditions at the moment of loading rock mass on conveyor 2 through the window 14 on the opposite side, when the rise of the rock mass chain with scrapers 6. The chain speed with scrapers 6 must be synchronized with the speed of the circuit downloadable 1 and the unloading conveyor 2, for simultaneous overload of the rock mass.

The proposed invention has a simple structure, and also will allow you to effectively and safely overload the rock mass from one conveyor to another, which are at the same level, without the mind is nisene performance conveyor line.

Device for handling of bulk material containing inclined and horizontal sections with drive placed on the support between the two conveyors, characterized in that the device is placed in the case with Windows located on the sides of the conveyors, and made in the form of a chain with scrapers, covering the rollers and mounted for movement in a pair of trapezoidal guides, and a housing mounted on a support using a hydraulic Jack, and the angle of α lateral sides of the trapezoid choose 35-45°.

Vibrating feeder // 2247068

FIELD: mining industry.

SUBSTANCE: invention relates to vibrating facilities and it can be used for letting out ore or other materials and their separation. Proposed vibrating feeder has resilient supports, working member consisting of charging and discharge parts and vibrating drive consisting of two shafts with unbalance weight and motors, one per each unbalance weight. Place of arrangement of vibrating drive is determined basing on the fact that line of connection of axles of unbalance weights is located in area limited by two straight lines square to direction of vibration, one of which passed through center of mass, and the other is located at a distance from center of mass of 1/10L to side of charging part of working member. Axle of unbalance weights are located at different sides from line of direction of vibration passing through center of mass at distance equal to not less than 1/8 where L is distance between resilient supports in horizontal direction.

EFFECT: improved stability of operation of vibrating feeder at unstable supply and impact loads on working member at discharging.

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.
