Description

The invention relates to the mining industry and can be used for the clearing of coal mines.

The aim of the invention is to increase the efficiency of excavation and improve the grade of coal.

The invention allows to work out layers with false roofs without leaving protective coal packs due to a rational assembly of screws of the executive body, providing it with the possibility of advancing the lower part of the reservoir, reducing the width of the bottom hole, crushing oversized coal and loading the upper part of the platform directly onto the conveyor.

Figure 1 shows a combine, general view from the side of the face; figure 2 - the same plan.

The combine is a design of symmetrically located relative to the transverse axis of the main body of the working units: mechanism 1 feed combine located in the center of the case, right 2 and left 3 electric motors associated with fixed gear 4 and 5, screws 6 and 7, installed but the ends of the case a combine (from the front side) on rotary handles x 8 and 9 mounted on the shafts of gearboxes and augers 10 and 11 mounted on rotary handles x 12 and 13 mounted on the shafts of gearboxes. In this psheki 10 and 11 are close together and are located symmetrically relative to the transverse axis

enclosures. The movement of the bike through the conveyor is carried out with the help of reg. shims 14 and 15. The raising and lowering of the rotary knobs is produced by hydraulic jacks 16–19.

The coal excavation by the combine is carried out with the division of the nlast by power into two parts and with the advance of the breast at the bottom of the upper part 20 of the breast at the bottom of the lower part 21 of the formation. When the combine moves along the conveyor 22, the spike 10 destroys the lower stack of the reservoir, leaving the scarp 23 as high as the side of the conveyor. At the same time, broken coal under its own weight flows down but the ledge on the conveyor. Screw 11 carries out the excavation of the ledge 23 and the stripping of the soil of lava. The lagging upper part of the reservoir, which is preceded by a leading lower part of the reservoir, is destroyed by seam 7 and is conveyed to the conveyor under its own weight. By the screw 6 located by the conveyor line, the oversize of coal is destroyed. After the passage of the harvester under the top 1-110 0 of the reservoir, the conveyor is moved. At the approach to the END of the lava, the combine carries out a dust tube, 1 I am moving it to the bottom of the iipn operating speck, iioc. Ie of which the process ;; ammkp is carried out in an ap- plicable settlement: 1).

The operation of the harvester is possible in accordance with the usual technology - we take out the HOCTii cho at full capacity (without the formation of pas seam pa part with onvniennux P1pekah 6 and 7.
