SU145505A1 - Combine for excavation of coal holes drifts on thin steeply dipping seams - Google Patents

Description

Combines for excavation of coal faces of drifts along thin steeply dipping seams are known, consisting of an executive body in the form of an annular bar with a double-hinged cutting chain, equipped with teeth and scrapers.

The described combine for excavation of coal faces of drifts along thin steeply dipping seams differs from the known ones in that the frame of the executive body is provided with windows.

This embodiment of the design of the executive body of the combine makes it possible to drill drainage and drainage wells without removing the combine from the bottom.

The feature of the proposed combine soloit is also that the screw conveyor and the elevator can be driven from one engine and gearbox via an intermediate compensator located at the drive sprocket between the elevator scrapers.

This allows to simplify the design and reduce the size of the combine.

FIG. 1 shows the proposed combine in the plane of the reservoir; in fig. 2 shows a combine in a plane located across the strike of the formation.

The combine executive member is a curved annular bar, equipped with a two-hinged chain with teeth and scrapers. Replaced coal is transported to the screw conveyor 2 by scrapers attached to the lower branch of the chain. The screw conveyor transports the coal along the screw to the scraper echew 3, which feeds the coal to the cart or to the material handler.

The design of the cutting body allows drilling of degassing wells with a BVU type machine without removing the combine from No. 145505-2-,

Bo, for which windows are provided in the frame. Drive 4 of the executive body and feed is located in the lower part of the cutting body. The cutting body and the feed of the combine are driven through one main gearbox 5. A drive sprocket of the cutting chain is mounted on one output shaft of the gearbox, and the drum of the feed part is mounted on the other output shaft of the gearbox. The rope on the drum when the combine is fed to the face is wound with a chain hoist.

The harvester is guided in power and dip formation by side bramies 6 and lower skis 7. For protection from coal ejection, shelves 8 are provided in the top part of the bottom, which is hinged to the bar and rests on racks punched under it. The harvester is ahead of the rock bottom, which allows drilling and blasting of the rock without removing the harvester from the bottom. The screw conveyor 2 and the scraper elevator 3 are driven from one engine 9 and gearbox 10 via an intermediate compensator located at the drive sprocket between the elevator scrapers. After the combine is advanced to the required distance, it is stopped and production is fastened. Before blasting the rock, organka is punched at the cutting organ, and the screw conveyor is covered to protect it from the blasted rock. At the end of the rock harvesting, the drainage wells are drilled, then the teeth are replaced and a thrust post 11 is installed for further operation of the combine.

The combine is intended for passage of shchtrek in mines, hazardous by sudden emissions of coal and gas, for which remote control they made a safe distance.

Claims (2)

1. Combine for excavation of coal faces of shchrek along thin steeply dipping seams, consisting of an executive body in the form of an annular bar with a double-hinged cutting chain, equipped with teeth and scrapers, characterized in that in order to drill drainage-degassing wells without removing the combine from the slab The frame of the executive body is provided with windows. 2. A combine according to claim 1, characterized in that, in order to simplify the construction and reduce the dimensions, the screw conveyor and the elevator are driven from one motor and gearbox via an intermediate compensator located at the drive sprocket between the scrapers of the elevator.
