The invention relates to machinery for underground selective excavation thin, mainly potash seams treatment combines.

Known processor for selective extraction of coal and rock, including motor, gear cutting parts, height-adjustable screw working bodies located at both ends of the housing, the conveyor, the feed mechanism, characterized in that the purpose of a more complete excavation and improve the quality of extracted coal and simultaneous transportation of slaughter coal and rock concurrent threads it has on the goaf side of the cutting part and independently moving the height reducers-rocking chairs on the ends of which are mounted loaders, augers are placed in open trenches with handling Windows in units and are movable chute connected with open gutters and the rocking guide and jacks [1].

The harvester can remove thin layers of coal with presecco rocks soil or roof of the reservoir. However, this combine with additional gears-rocking chairs on the ends of which are mounted cranes with augers in open gutters with handling Windows and open-air troughs connected with open gutters and rocking guides and a hydraulic Jack, is a complex design is Yu, that increases the probability of failures of individual nodes combine.

Also known processor for selective mining of minerals, including the shell, the ends of which are mounted to rotate in the vertical plane of the two arms, respectively provided with a built-in drive and auger, each handle connected to the housing via a bracket, one end of which is pivotally connected with the machine body, and the other provided with a guide, which has referred to the handle to move it in a horizontal plane perpendicular to the longitudinal axis of the combine [2]. However, the presence of the harvester two massive sites for nomination to the bottom of the handles with integrated actuators and augers with loading plates substantially increases the weight and cost of selective harvester.

The closest in design to the claimed technical solution is a processor for selective extraction polegada layers of minerals occurring in the middle part of the rock interlayer, comprising a housing with skis and clamps for connection to the face conveyor, the Executive bodies in the form of a screw actuators and loading plates for the extraction of minerals and the Executive body for excavation of rock stratum, made in the form of the cutting drum is with a vertical axis of rotation, which is set for screws for the extraction of minerals ahead in the direction of the face, when the loading flap is positioned beyond the last in the direction of the auger and is made with possibility of installation of displacement height, and the harvester is provided with an additional frame for mounting the Executive body for excavation layer, a frame pivotally connected with the machine body, a fixed cutter drive for excavation of rock layer [3].

When turning relative to the reference frame of the cutting drum is in a position to advance the excavation of the rock layer behind the screw in the direction of travel of the harvester.

The disadvantage of this design is its complexity in the presence of the third Executive body for extra support frame, which reduces its reliability and performance respectively.

The objective of the invention is to simplify the design of the combine, reduce its weight and increase reliability when selective extraction of thin layers with presecco roof rocks.

The technical result is achieved by the fact that the harvester for the selective extraction of thin layers of minerals, including the shell, the ends of which are mounted to rotate in a vertical plane, two handle, respectively provided with a built-in PR what Odom and screw with the loading flap, and bracket, and one of the handles has rigidly secured to it the slider can move it with the handle in the guiding groove of the bracket to the bottom hole on the value not less than the width of the screw, the diameter of which no more than the capacity of the rock layers of the roof, placed in the rotating drum between the shaft and the conveyor and screw the other handle is made with a diameter of not less than half of the total capacity thump of hands of the rock layers of the roof and fossil.

Figure 1 shows the scheme of the combine, the view from the side of the longwall face; figure 2 is a view of the harvester from the top.

Harvester for the selective extraction of thin layers comprises a housing 1 containing two feeder 2 and 3 and two swivel in the vertical plane of the handle 4 and 5, hinged at the ends of the housing 1.

The handle 4 and 5 respectively provided with integral actuators 6 and 7 and screws 8 and 9. The diameter of the screw 8 is not less than half of the total capacity of the rock layers of the roof and minerals, and the diameter of the screw 9 is not more than the power of the rock layers of the roof, placed in the rotating drum between the shaft and the conveyor. The handle 4 screw 8 pivotally connected to the housing 1 of the harvester can be rotated in a vertical plane by means of hydraulic jacks lift 10. The handle 5 of the screw 9 pivotally connected to the housing 1 of the harvester by means of bracket 11. In addition, the handle 5 of the screw 9 is attached rigidly to the floor of the University 12. The bracket 11 on the one hand has a swivel 13 and 14, connecting respectively with the housing 1 of the harvester and the hydraulic cylinder 15 of the lifting arm 5, and on the other guide groove 16, into which you have inserted the slider 12 with the possibility of longitudinal movement by means of hydraulic cylinder 17 to the bottom in the plane perpendicular to the longitudinal axis of the harvester, by a value not less than the width of the screw 9.

The harvester works as follows.

After the notches combine one of the known methods for early excavation of the layers of the roof put forward in the roadway screw 9 by moving the slider 12 with the handle 5 in the guide groove 16 of the bracket 11 by means of the hydraulic cylinder 17. Then screw 9 on the roadway is exposed in a vertical plane by means of the hydraulic cylinder 15, which interacts with the bracket 11 via a hinged connection 14, turning this bracket 11 together with the slider 12, the handle 5 and the screw 9 in the hinge connection 13 capacity removable layers of the roof above the reservoir of minerals, and the screw 8 by the hydraulic cylinder 10 is set in prepared with a cut face for useful minerals. When the movement of the harvester to the opposite side of the lava screw 8 goes Nude in the previous cycle, the formation of minerals with loading it onto the face conveyor with standard shield (not shown), as by a screw 9 behind šnē the 8 beat ahead of the width of the auger rock layers of the roof with the placement of the rocks between the bottom and the pipeline.

During the reverse course of the harvester auger 8 are loading on the AFC repulsed by a screw 9 rocks and laying it in a goaf lava.

A new cycle begins after the notches combine and advancing the AFC and lining. The use of the proposed solution will improve the efficiency of selective extraction of thin layers of minerals by simplifying the design of the processor, reducing its weight and cost.
