The invention relates to mining, in particular to the mechanization of work in the Stopes using mechanized roof supports, connected to the conveyor base of the mining machine.

A device for connection of the shields with the conveyor, comprising a bracket rigidly mounted on the linear section of the conveyor and connected through a hinge to a support, which, in turn, is connected via a hinge with the beam sections of powered roof supports, the axis of the hinge between the support and the beam is in the vertical plane and the axis of the openings between the support and the bracket is located in a horizontal plane, hydropattern to control the linear conveyor section in a vertical plane, pivotally connected with the bracket and the support, a plow located on the downhole side section of the conveyor while the horizontal hole of the hinge in the support is made in the form of a vertical groove /1/.

A disadvantage of the known device is the low efficiency in pollution due to tastybaby vertical groove bearings.

Vertical groove bearing is always open all cycles of the shields. Accordingly it gets dirt (dross) and fill it, thereby limiting the vertical movement of the bearing and, accordingly, the rotation angle of the linear section of the pipeline that reduced the t efficiency samnewali smitten rock mass when the valve is in the pipeline.

A device for connection of the shields with the conveyor, comprising a bracket rigidly mounted on the linear section of the conveyor and connected by a vertical hinge support, which, in turn, connected by a horizontal hinge with vertical ribs sections of powered roof supports, and the horizontal hole of the hinge in the support is made in the form of a vertical groove, hydropattern to control the linear conveyor section in a vertical plane, mounted on the mechanical prop plane, with the plunger of hydropattern interacts with the beam sections of powered roof supports, and the course of hydropattern control conveyor in a vertical plane more than offset the supports relative to the beam shield in the vertical plane, ploughshare, located on the downhole side of the conveyor. /2/

A disadvantage of the known device is the low efficiency in pollution due to tastybaby vertical groove bearings.

Dirt particles (AC - fine particles, until pulverized, broken rock mass and coal) accumulate before you pushed the basis of the shields. Through the gaps dirt penetrates and accumulates on the bottom fillet vertical groove.

When the valve pipeline hydropattern changes the rotation angle of the linear section to the Weyer, raising his dammed part and, accordingly, reliance on the stroke axis in the vertical groove. The lower fillet vertical groove bearings when this is pressed against the axis, stamping it crashes into the dirt. This happens in each cycle of valve pipeline, up to the full tastybaby vertical groove and move it into the hole, which reduces the rotation angle of the linear section of the pipeline and reduces the implementation effort plowshares into the soil.

The basis of the invention is the task of improving the health of the device in terms of pollution.

To solve the problem in the known device for the connection of the shields with the conveyor, comprising a bracket rigidly mounted on the linear section of the conveyor and connected by a vertical hinge support, which, in turn, connected by a horizontal hinge with vertical ribs sections of powered roof supports, with one of the holes of the horizontal hinge is made in the form of a vertical groove, hydropattern control the linear section of the conveyor in a vertical plane, mounted on the mechanical prop plane and a plunger which interacts with the beam sections of powered roof supports, and the course of hydropattern control linear conveyor section in a vertical plane greater than the displacements of supports the relative beam shield in a vertical plane, ploughshare, located on the downhole side section of the conveyor according to the invention the vertical groove is made in the form of two coaxial grooves, each of which is located in the vertical edge of the beam sections of powered roof supports.

In addition, rounding vertical grooves made with bevels, the vertex of the angle between each vertical groove directed toward the support.

Conducted by the applicant's analysis of the prior art, including the search for patents and scientific and technical sources, has allowed to establish that it is not detected similar, characterized by signs, identical to all the essential features of the claimed device set forth in the claims.

Therefore the proposed device complies with the conditions of patentability of an invention is "new".

In contrast to the prior art, the smaller the width of the vertical slots in comparison with the width of the vertical groove in the support, a permanent cover the bottom fillets finger horizontal hinge, since the latter, initially, is in the lower position and rises, i.e. detached from the bottom fillets only in the process of pipeline valves, dramatically reduce the likelihood of dirt on the bottom fillet vertical grooves and, consequently, the probability that tastybaby. Dirt falling on the upper hemisphere alcoholcontaining hinge on the plots of the width of the vertical ribs of the section of powered roof supports, pressed it with your finger to the top of the fillets vertical grooves. And after lowering the axis at the end of the process valve to the pipeline, a large part of the compacted rubble showered down, thereby reducing the likelihood of tastybaby vertical groove.

In addition, the presence of slanted fillets vertical grooves allows you to squeeze out the dirt that falls into the vertical grooves on the axle and under the horizontal axis of the hinge when raising and lowering the support, i.e. to produce self-cleaning vertical grooves in each cycle of the valve in the pipeline.

A smaller amount of dirt falling into the vertical grooves and remove penetrated them dirt during operation of the device provides a nominal vertical movement of the support. And this, in turn, assures optimum position of the shields pipeline and power modes when the valve is linear section of the conveyor for samnewali smitten rock.

Thus, the essential features of the claimed invention are in causal relationship with achievable technical result and analysis of the prior art in this field is not obvious explicitly for professionals. Therefore, the claimed invention meets the condition of patentability of invention - "inventive step"

Device for connection of the shields with the conveyor consists of a bracket 1 fixed on the linear section of the conveyor 2 and connected by a vertical hinge 3 with a support 4, which, in turn, connected by a horizontal hinge 5 with vertical ribs 6 of the beam sections of powered roof supports 7. The opening of the horizontal hinge 5 in the vertical ribs 6 are made in the form of two coaxial grooves 8 with fillets 9. Hydropattern control conveyor in a vertical plane 10 is fixed on the end plane 11 support 4, with the plunger of hydropattern 12 interacts with the beam sections of powered roof supports 7. The course of hydropattern 10 control linear conveyor section in a vertical plane more than offset support 4 relative to the beams 7 of the shields in the vertical plane. In addition, fillets vertical grooves 9 are made with bevels 13, top 14 of the angle α between them on each vertical groove directed toward the support 4. Downhole side of the linear section of the conveyor 2 is provided with shingles 15.

Device for connection of the shields with conveyor working the AET as follows.

Valve pipeline is carried out wave after passage of the mining machine. While the linear section 2, the components of the conveyor are rotated in a horizontal plane relative to the hinge 3. Because the hinge 3 is located at a minimum distance from the linear sections of the conveyor 2, the rotation is performed with minimal longitudinal displacement, i.e. without the formation of waves in the vertical plane, and means plowshares 15 linear sections of the conveyor 2 are situated in one plane, thereby providing the most effective Samoylenko smitten rock mass on conveyor.

When the valve of the pipeline changes the angle of inclination β of the linear section of the conveyor 2. The working fluid under pressure supplied into the cavity of hydropattern 10, a plunger 12 which, based on a beam section of powered roof supports 6, raises the dammed part of the linear section of the base 2 through a bearing 4, since the linear conveyor section 2, the bracket 1 and the support 4 in a vertical plane perpendicular to the slaughter, are invariant geometric system. After selecting move in the vertical grooves 8 formed by two shoulders lever, one arm of which is linear conveyor section from the plow blade 15 to the axis of the hinge 5, the other is the distance from the axis of the hinge 5 to the axis of hydropattern 10. And the further course of hydropattern 10 is implemented through the chief the t of the lever, thereby making the forced introduction of the plow blade 15 in Stepovoy the pillow.

Dirt (dross) with valve pipeline, penetrating into the gap horizontal hinge 5, testimonial holes in the support 4 down to zero, without interfering with normal operation of the hinge 5. Further tastybaby this hinge stop here.

Dirt falling into vertical grooves, when raising and lowering the supports 4 and, respectively, the horizontal axis of the hinge 5 is pressed past the bevels 13 in the side of the beam 7.

The use of the device for connection of the shields with the conveyor allows to increase the efficiency of the device in terms of pollution due to getting a smaller amount dirt and cleaning vertical grooves during the execution device of the basic technological operations, changing the angle of inclination of the conveyor and enforcement plowshares into the soil.
