The invention relates to the mining industry, namely rasstilalsya for scraper conveyors intended for removal of rubble from the lower branch of the conveyor and also for unloading coal, transported out of the lava in the transport production when Shearer or plow the excavation of minerals.

Known restinosis removal of SByte with the lower branches of the scraper conveyor comprising a working body in the form of a chain with a console scrapers, covering the sprocket mounted on the output of the data with him the disk and the pin, moreover, the output shaft of the gearbox and sprocket conveyor connected planet carrier [1].

The disadvantage of rasstilalsya is that it has a significant size and complicated in technological performance, because structurally combined with a transition section of the scraper conveyor.

In addition, the sprocket drive head rasstilalsya connected through the carrier to the output shaft of the gearbox of the conveyor, and this means that he cannot work independently of the drive of the scraper conveyor.

All this complicates the installation work with the joint Assembly of the transition section of the scraper conveyor and rasstilalsya, because they must work as a single mechanism for the removal of chips from the working body of the scraper conveyor.

And this restinosis does not allow Stripping of soil transport produce from made of lava rubble or fossil.

Thus, these disadvantages reduce its performance, and therefore it is not efficient enough in the work.

Known restinosis used to remove rubble from the lower branches of the scraper conveyors, working body which is driven through the reduction gear Conway in the horizontal plane at an angle its upper branch passes between the branches of the scraper chain conveyor, and the lower, working branch under idle lower branch of the conveyor [2].

The disadvantage of rasstilalsya is that it offers limited functionality, since it is rigidly connected with a transition section of the scraper conveyor, and therefore cannot change its position relative to the axis of the scraper conveyor in order to make cleanup of soil production from the rubble made it out of the lava, over a larger area.

In addition, in this rustybovine the upper groove of the rod together with the chain passes through the slot of the frame actuator located between the branches of the scraper chain conveyor being located so across the top branches of the scraper chain, and it worsens the conditions of the displacement of coal with a scraper conveyor for gathering conveyor and inconvenience in operation of the scraper conveyor.

Remove rubble from the working body of the scraper conveyor is a single (lower) branch circuit rasstilalsya, which reduces its performance.

Moreover, considering restinosis, as well as similar [1], is structurally integrated with the drive scrubbing is haunted by embedding elements for introducing them to the design of the scraper conveyor. Such a relationship rasstilalsya with the conveyor drive reduces overall operational capability.

The deficiencies noted in General reduce the efficiency of the known rasstilalsya when removing rubble directly from the working body of the scraper conveyor and other possible places his accumulations within the location of the transition sections of the pipeline.

The basis of the invention have been tasked to increase the efficiency of rasstilalsya at the expense of functionality while providing the convenience in operation due to independent operation of drive of the scraper conveyor.

This object is achieved in that in rustybovine for scraper conveyors, including the drive, the working body in the form of krupasindhu chain with console scrapers, closed through drive and idler sprockets to form two branches and moving the rod deflecting drums, according to the invention becoming, which is a loop made in the form of a closed chute and curved in the vertical plane by deflecting drums with the formation of two streams consisting of horizontal inclined parts, oriented, parago rod, both branches of the closed circuit are working, moreover, the horizontal portion of the rod located under the lower branch of the scraper conveyor and each of them is a window opposite said branch conveyor and the inclined portion of the rod together with their connecting curved section located above the working top branch of the scraper conveyor to allow rash of rubble at her through the hole made with the bottom of the said plot for the drive sprocket at the end of a curved section of the rod connecting it to the horizontal part, for tensioning sprocket covered by closed circuit made the cut closed with a protective cover, hinged to the horizontal parts of the rod, moreover, the drive offline placed on the outer side of the curved section of the rod, between the inclined part and coaxially with the drive sprocket, with restinosis equipped with hydraulic cylinders located on each side of the scraper conveyor and associated with the rod for turning of rasstilalsya in a horizontal plane about the axis of the scraper conveyor.

In comparison with the prior art the invention is directed to restinosis could work independent is and scraper conveyor, as well as of the possible places of accumulation in soil transport output. All this allows to extend the functionality of the proposed rasstilalsya and, accordingly, to increase the effectiveness of work to remove rubble from the soil develop at the site of its pairing with lava.

This is achieved due to the fact that becoming made in the form of a closed trough that moves the working body in the form of a closed circuit, and becoming curved in the vertical plane through the deflecting drums with the possibility of formation of two horizontal and two inclined portions and two curved sections connecting respectively referred to part with each other. Both the horizontal part of the rod is located under the lower branch of the AFC and its sloping side - on working the upper branch of the scraper conveyor.

The proposed curved form of execution of the Constitution, which respectively repeats enclosed therein a closed circuit, with the formation of two business branches eliminates constructive relationship rasstilalsya lattice rod scraper conveyor, while providing the convenience of its operation.

The bending of the rod in the vertical plane to provide the branch conveyor, because they are working.

Using a drive that is not associated with the drive of the scraper conveyor and located on the outer side of the curved section of the rod that connects the inclined part, coaxially with the drive sprocket covered by closed circuit allows to provide Autonomous operation of rasstilalsya and AFC, while enhancing their performance.

Performing in each horizontal part of column one window opposite the lower branches of the scraper conveyor allows you to remove her staff with both branches closed circuit because they are working, and it provides the most comprehensive rasstanovku working body of the scraper conveyor.

The presence of the recess in the rod for tensioning sprocket where one horizontal portion goes to another horizontal part, allows you to capture the rubble console scrapers with soil production, which brought coal from longwall extraction of minerals.

To ensure the safety of maintenance personnel when the dross is removed only from the lower branch of the conveyor, in the design of rasstilalsya provides protective TREN unloading rubble of niches lava however, it is unsafe, because the lower branch closed circuit carrying this rubble on the gathering conveyor moving along the open trench.

In addition, on the lower side of the curved section of the rod that connects the inclined portion, for driving the sprocket, there is a hole, through which poured the rubble on the working branch of the scraper conveyor and is then transported together with minerals brought to the place of overload. This generally simplifies the technology unloading rubble of their accumulation at the site of conjugation of lava with transport development.

Known restinosis for scraper conveyors [3], in which the working body in the form of a tray. After downloading the rubble from the lower branches of the scraper conveyor is he using a setting device, without changing the horizontal position, moves up parallel to itself with subsequent rotation at the end of the route for discharging the delivered chips on the conveyor.

In this technical solution [3], as claimed, the discharge of chips is carried out directly on the working branch of the scraper conveyor. However, the discharge of chips on the conveyor in the technical solution [3] is carried out as the respectively, and the effectiveness of its work.

Another disadvantage of the known rasstilalsya [3] is the design complexity of the working body, which makes it unreliable in his work.

These disadvantages of the known rasstilalsya [3] is not inherent in the claimed rasstanovku, because in recent removal of chips from the working body of the scraper conveyor is carried out using both branches closed circuit held separately on the horizontal parts of the composition, and the discharge of chips is carried out under its own weight through the opening in the curved section of the rod that connects the inclined part.

In addition, the claimed restinosis movable relative to the scraper conveyor. This is achieved by using hydrocyclones mounted on the sides of the panline scraper conveyor and connected with the horizontal part of the composition of rasstilalsya. Mobility rasstilalsya in the horizontal plane allows the Stripping of soil excavation over a larger area than the prototype [2]. While the capture of rubble is a console scrapers when they are cut in the rod, namely at the location of the idler.

Thus, isklucheniya binding to it, the use of both branches of the closed circuit of the working body of rasstilalsya for the most complete removal of chips from the working body of the scraper conveyor, the possibility of loading of coal brought into the niche of lava, mobility rasstilalsya in the horizontal plane for the removal of rubble from a larger area accumulation, all of this allows you to extend the functionality of the proposed rasstilalsya, i.e., the achieved technical result, which is not obvious from the prior art, and therefore it has an inventive step.

In Fig. 1 shows the described restinosis for scraper conveyors, longitudinal section; Fig. 2 is the same as in Fig. 1, a top view (oblique parts 10, 11 and the protective cover 21 is conventionally not shown); Fig. 3 is a view along arrow a of Fig. 1.

Restinosis for scraper conveyors includes an actuator 1, a working body, made in the form krupasindhu circuit 2 console scrapers 3 closed through drive 4 and a tension of 5 stars with the formation of two branches and moving the rod 6 and the deflecting drums 7 with a horizontal orientation of their axes. Becoming 6 made in the form of a closed chute and curved in the vertical plane posnik parts 10 and 11, oriented parallel to each other and interconnected by curved sections 12, 13, i.e., the curved section 12 of the rod 6 connects the horizontal portion 8 and 9, a curved section 13 of the rod 6 is its sloping parts 10 and 11. Using a bent rod 6, both branches of the circuit 2 is oriented in a vertical plane and at the same time are working, because the participate in the movement of rubble inside the closed rod 6.

While the drive sprocket 4 circuit 2 is placed in a curved section 13 of the rod 6, between the inclined parts 10 and 11, and a tension sprocket 5 chain 2 in the curved section 12 connecting the horizontal portion 8, and 9.

The horizontal part 8 and 9 of the rod 6 is located under the lower branch 14 of the scraper conveyor 15, and its sloping parts 10 and 11 together with their connecting curved section 13 is placed over the working of the upper branch 16 of the scraper conveyor 15. Moreover, in the horizontal parts 8 and 9 are made of the window 17 and 18 opposite the lower branches 14 of the scraper conveyor 15 for sifting through them of chips on each branch circuit 2, a prisoner and a bent rod 6.

To enable rash of rubble on the upper branch 16 of the conveyor 15 under its own weight OI a closed circuit 2.

To remove dross or coal, accumulate, for example, on grounds of production in the place of its pairing with clearing face or niche stope at the end of a curved section 12 of the rod 6 for tensioning sprocket 4 covered by closed circuit 2, the cut-out 20, blocked the protective casing 21, a hinge mounted on the horizontal portions 8 and 9.

The actuator 1, as a self-contained, placed on the outer side of the curved section 13 and coaxially with the drive sprocket 4 covered by the circuit 2.

For turning of rasstilalsya in the horizontal plane it is supplied by hydraulic cylinders 22 located on each side of the scraper conveyor 15 along its longitudinal axis and connected with the rod 6, for example, with its horizontal part 9.

Work rasstilalsya described on the example of its use on the site pair production with clearing face, rounding circuit 2 idler sprocket 5, it will be in the horizontal part 9 of the rod 6, which also pours out of the rubble with the lower branch of the conveyor 14 15 along its moving (back arrow B in Fig. 2) through the window 18 and scrapers 3 again capture the rubble 3. Then chain 2, moving up the inclined part 11 with zagruzhennym, delivered scrapers 3, under its own weight poured on working the upper branch 16 of the conveyor 15. Since the cut-out 20 is blocked by the casing 21, the rubble is not taken out of the rod 6 to the outside.

If necessary, reverse the direction of movement of the chain 2, it passes the parts of the rod 6 in reverse order. Such a need may occur if restinosis will be deployed 180o.

If there is no need to remove rubble from the working body of the scraper conveyor 15, the protective casing 21 throw back and scrapers 3 loaded with rubble through the cut-out 20 in the rod 6 in the presence of, for example, on grounds of production in which it is taken out of the stope extraction of minerals.

To get a large area of Stripping the soil of the output from the rubble, include hydraulic cylinders 18 and use them to manipulate the position of rasstilalsya about the axis of the scraper position.

Thus, the claimed restinosis provides the removal of chips from the working body of the scraper conveyor with a mix of the two branches of a closed circuit, as well as of the possible places where the rubble, soil production running operation overload debitoren: restinosis brought under panline scraper conveyor 15; krugosvetnaya closed circuit 2 is inside the rod 6, both branches of which are curved in the vertical plane; working branch 16 of the scraper conveyor 15 moves in the direction of the arrow B shown in Fig. 2, i.e. to the place of overload transported them of minerals; the horizontal part 8 and 9 of the rod 6 is oriented, for example, in the direction of movement of the stope (not shown); the protective cover 21 closes the slot 20 in the curved section 12 of the rod 6.

Turning the actuator 1, the torque is transmitted from the drive sprocket 4 and connected to it a chain with 2 scrapers 3 is driven in the direction of arrow B (Fig. 2) curved rod 6. The chain 2, around the drive sprocket 4, passes through the inclined part 10, around 6 becoming in the place of his bending using a deflecting drum 7, moves in the horizontal part 8 covers the idler sprocket 5 and passes through the horizontal part 9 of the rod 6. Then again, becoming rounded 6 at its bend, passes through the inclined part, a single drive sprocket 4.

Moreover, when the circuit 2 moves downward along the inclined portion 10 of the rod 6, it scrapers 3 is not loaded with rubble and moving in the horizontal part 8 and passing over the window 17 through compedative spilled the rubble and carry it further along the rod 6. After rounding circuit 2 idler sprockets 5, it will be in the horizontal part 9 of the rod 6, which also pours out of the rubble with the lower branch of the conveyor 14 15 along its moving (back arrow B in Fig. 2) through the window 18 and scrapers 3 again capture the rubble. Then chain 2, moving up the inclined part 11 with the loaded styble scrapers 3, is curved section 13, which has a hole 19. Through this opening 19 dross delivered scrapers 3, under its own weight poured on working the upper branch 16 of the conveyor 15. Since the cut-out 20 overlaps the casing 21, the rubble is not taken out of the rod 6 to the outside.

If necessary, reverse the direction of movement of the chain 2, it passes the parts of the rod 6 in reverse order. Such a need may occur if restinosis will be deployed 180o.

If there is no need to remove rubble from the working body of the scraper conveyor 15, the protective casing 21 throw back and scrapers 3 loaded with rubble through the cut-out 20 in the rod 6 in the presence of, for example, on grounds of production in which it is taken out of the stope extraction of minerals.

To cover a large area of soil Stripping exp axis of the scraper conveyor.

Thus, the claimed restinosis provides the removal of chips from the working body of the scraper conveyor with a mix of the two branches of a closed circuit, as well as of the possible places where the rubble on the ground production from the horizontal portions 8, 9 of the rod 6, which extends its functionality while providing convenience in use.
