This invention relates to the coal industry and may be used in a shield system for the development of thick steep seams.

The aim of the invention is to increase the efficiency of the combine by providing a shuttle excavation scheme without turning the entire combine.

FIG. 1 shows a combine, general view; in fig. 2 7 the same, top view; in fig. 3 is an example of a steep seam mining with a shield development system using the proposed combine.

The coal combine includes a tracked undercarriage 1, on the frame 2 of which there is an annular conveyor 3 with cantilever scrapers 4 and side branches 5, a turntable 6 with lugs 7 and a case a on which the articulated executive organ 9 is pivotally mounted, on the case 8, additional lugs 10 are fixed at the same distance from each other at the same time. The turntable is installed in the central part of the combine, while the ring conveyor 3 is symmetrical with respect to the vertical 11 and g rizontalnoy axes 12 extending through the central part of the harvester, and a hinged side legs of the middle part 5 and combine with the possibility of lifting and lowering with respect to the front 13 and rear 14 parts of the harvester by means of hydraulic jacks 15 lift.

The lugs 10 cling to the heads of the rods of the hydraulic jacks 16. The coal miner is designed to work under shield overlap 17, the broken coal is transported from under the actuator by an annular conveyor, poured into the soil behind the combine and from there is transported by a tS scraper to the nearest coal drain furnace using scraper Winches 19, located at the ends of the bottom.

Coal harvester works as follows.

The harvester is mounted in the ditch under the shield overlap 17 and produces coal extraction under the shield according to the shuttle pattern. Moving forward on tracked undercarriage 1, an arrow-shaped crown-type executive body 9 cuts support-. pillars, extends and deepens the ditch. Repulsed coal is transported from under the executive body 9 by an annular conveyor 3 for a combine, the craft is transported

using the scraper 18 to 1 of the nearest coal-fired furnace with the help of a scraper winch 19. Two hydraulic jacks 16, the cylinders of which are fixed on the frame 2 and the heads of the rods for the lugs 7, rotate the lifting-turning device 6 together with the executive body and around the vertical axis 11 After the next strip is removed by the coal at the end portion of the bottom 0, the combine is re-mounted to work in the opposite direction. To do this, use the hydraulic jacks 16 to turn the tilt-and-turn device 6 together with the executive body 9 to an extreme 5 the fixed angle uncouples the heads of the rods of the jacks 16 from the springs 7, transfers the heads of the rods to the successive additional lugs 10, and again rotates the tilt-up device 0 6 in the same direction, sequentially performing 3-4 such operations, turn the lifting-tilting device 6 together with executive body 9 at 180 °. . Then the ring conveyor 3 is lowered relative to the rear part of the combine 14 and at the same time another part of the conveyor is raised relative to the front part 13. After that, the combine produces coal excavation in the opposite direction.
