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 via a hinge with the beam sections of powered roof supports, hydropattern with the plunger to control the linear conveyor section in a vertical plane, pivotally connected with the bracket and the beam sections of powered roof supports, ploughshare, located on the downhole side of the section of the pipeline [1].

A disadvantage of the known device is the low efficiency of Stripping, due to the limited ability to track hypsometry soil plowshare with valve pipeline wave.

The hinge connecting the conveyor beam section mechanized lining, made in the form of a cylindrical connection, which allows an unlimited angle of rotation in one plane only. In all other planes, in particular in the vertical, perpendicular to the bottom, the rotation can be done only within the gap between when the power transmission, required to operate the conveyor. If you increase this gap in direct proportion to the contact voltage increase in the power-law dependence. And limited angle of rotation does not allow the pipeline when the valve is effectively track hypsometry soil and ledges and hollows formed by auger mining combine, which reduces the efficiency of the Stripping.

A device for connection of the shields with the conveyor (base), 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 hinge between the support and the bracket is located in a horizontal plane, and the horizontal hole of the hinge in the support is made in the form of a vertical groove, hydropattern with the plunger to control the linear conveyor section in a vertical plane, pivotally connected with the bracket and the support, ploughshare, located on the downhole side of the section of the pipeline [2].

A disadvantage of the known device is the low efficiency of Stripping, due to the constraints is of onveyer wave on this part of the linear section of the conveyor rotate in a horizontal plane. The axis of the hinge connecting the bracket to a support, is located in the horizontal plane, i.e., allows an unlimited angle of rotation only in one vertical plane. In all other planes, in particular in the horizontal, the rotation can be done only within the gap between the hole and the axis of the hinge. Thus, rotation in the horizontal plane of the linear section of the pipeline is carried out in conjunction with the bracket and the support relative to the hinge connecting the support and the beam shield. But this hinge offset from the linear section of the conveyor, i.e., forms a shoulder, and, consequently, rotation of the linear section of the database is performed with its longitudinal displacement, which is directed toward the mining of the combine, after a passage of which the valve in the pipeline. In turn, the force from the movement of the mining combine in opposite direction from the direction of its travel, i.e. in the direction of the wave of the valve. Thus, the section of pipeline between the wave valves and mining combine loaded compressive force. And because the gaps between the linear sections of the conveyor is selected, the passage mining combine, the longitudinal movement of the linear section of the database of povich linear sections of the base up. Thus, simultaneously with the "wave" in the horizontal plane in this area formed a "wave" in the vertical plane, which reduces the efficiency of the Stripping.

The basis of the invention is the task of increasing the efficiency of Stripping rock mass on conveyor by increasing tracking capabilities of hypsometry soil plowshare with valve pipeline wave.

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 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 one of the hinges is located in a vertical plane and the axis of the other of the hinge is located in a horizontal plane, and the horizontal hole of the hinge in the support is made in the form of a vertical groove, hydropattern with the plunger to control the linear conveyor section in a vertical plane, a plow located on the downhole side section of the conveyor, according to the invention the axis of the hinge connecting the support and the beam sections of powered roof supports, is located in a horizontal plane, and hydrometra the cartridge interacts with the beam sections of powered roof supports.

In addition, the stroke of the plunger of hydropattern control linear conveyor section in a vertical plane larger than the maximum displacement of the insert relative to the beam shield in a vertical plane.

In contrast to the prior art reducing shoulder when turning the linear section of the conveyor by moving the hinge axis in a vertical plane at a minimum distance from the pipeline can reduce the effect of waves in the vertical plane when the valve of the pipeline, i.e., a plow blade sections of the conveyor are arranged in one plane and uniformly produce sweep the entire length of the waves.

Increased stroke of hydropattern control linear conveyor section in a vertical plane with respect to vertical during insertion in the hinge forms two shoulders lever rotating about a horizontal axis, which allows the forced introduction of the plow blade base layer of chips and increases the effectiveness of the cleanup.

The analysis not only of the known technical solutions, but all of the prior art has revealed the characteristics of such claimed.

A device for connection of the shields with the conveyor, comprising a bracket rigidly mounted on LINEST is m joint with beam sections of powered roof supports, the axis of the hinge between the bracket and the support is located in a vertical plane, and the axis of the hinge between the support and the beam sections of powered roof supports located in the horizontal plane [3].

A disadvantage of the known device is the low efficiency of Stripping because of the dammed part of the linear section of the conveyor Prigogine mass of the beam line of the shields, and the vertical load acting on the beam side of the shields, and when the valve of the dross conveyor, accumulating under downhole portion of a linear section of pipeline as a lighter, causing it to rise, taking thus the share of the pipeline from the soil, i.e. not achieve the main technical task of Stripping the layer of rubble from the ground.

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 "inventive step".

In Fig.1 shows a device for connection of the shields with the conveyor; Fig.2 is a view As in Fig.1; Fig.3 is the same as in Fig.1, with a modified angle of the conveyor PTA 1, rigidly mounted on the linear section of the conveyor 2 and connected through a hinge 3 and a support 4, which, in turn, is connected through a hinge 5 with the beam sections of powered roof supports 6. The hole in the support 4 of the hinge 5 is made in the form of a vertical groove 7. Hydropattern 8 control linear conveyor section 2 in a vertical plane mounted on the end plane 9 support 4, the plunger 10 which interacts with the beam sections of powered roof supports 6. Linear conveyor section 2 is provided with plowshare 11.

Device for connection of the shields with pipeline works 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 section 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 11 linear sections of the conveyor 2 are situated in one plane.

If necessary, change the angle "B" of the linear section of the conveyor 2 during excavation of the rock mass Dobychin beam sections 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 on a vertical groove 7 support 4 forms two shoulders lever, one arm of which is a linear section of the base from the plow blade 11 to the axis of the hinge 5, the other is the distance from the axis of the hinge 5 to the axis of hydropattern 8. And the further course of hydropattern 8 is realized through rotation of the lever, thereby making the forced introduction of the plow blade 11 in Stepovoy the pillow.

Use your device to connect the shield with the base allows to minimize disturbance of the spatial geometry of the pipeline when the valve wave. If necessary, enforce the implementation of the plow blade linear section of the base in Stepovoy pillow. To reduce the force of the valve base, since the lower edge of the plow blade will move across the plane of the partition environments, soil formation - stibova pillow, because the movement of this edge in the layer of dross causes great efforts of resistance.
