Description

Known coal miners for working under the lining on steeply falling layers with the executive body of reinforced screws and drums on the boom prevent mechanization of coal extraction regardless of the thickness of the formation and the position of the lining in relation to the bottom.

The proposed coal miner does not have these disadvantages, since it is equipped with a trolley, with the help of which it is suspended on guide rails, reinforced pillars, telescopic racks, and the boom is equipped with a bucket conveyor that supplies coal to the ring-mounted loader mounted above the trolley.

FIG. 1 shows a combine in longitudinal section; in fig. 2 - combine in plan.

The harvester is intended for excavation of coal under the support on steep dip seams. The harvester with the help of a trolley / is installed on the guide beams 2 and moves along the driving mechanism 5. The actuator is fed into the strike spread by turning the boom around the vertical axis of the trolley. The harvester consists of an actuator, which is a screw head 4 and a drum 5 with teeth located between them, mounted on the horizontal axis of the boom 6. The boom is hinged on the trolley and equipped with a forging conveyor 7 for feeding coal to the ring conveyor 8. Coal from the ring conveyor enters the overhead conveyor and then into the coal-fired furnace.

The hinged boom mounting allows the coal to be excavated and loaded into coal-fired furnaces, regardless of the position of the ski lining relative to the bottom. The coal extraction by the combine is made from the middle of the bottom to the flanks.

Repulsed coal is loaded onto conveyors that transport it to the coal-fired downhole furnaces. After the belt is removed, the coal combine is placed in the transport position and the winch is delivered to its initial position along the guides, after which the landing gear is fixed on the bottom and the combine operation cycle ends.

1. A coal harvester for working under a support on steeply falling layers with an executive body in the form of augers and a drum with teeth, mounted on a boom, characterized in that, in order to mechanize coal mining regardless of the thickness of the formation and on the position of the ski support relative to the bottom, it is equipped with a trolley with which it can be mounted on guide beams fixed on telescopic supports.

2. Coal harvester P 1, characterized in that, in order to ensure the loading and delivery of coal to the downhole conveyor, the boom is equipped with a bucket conveyor (elevator) that takes the coal to the ring-mounted crane loaded under the carriage.
