a conveyor

Abstract

The invention discloses a conveyor for a coal-mine underground vertical-layer coal-mining working face. The conveyor comprises a machine head part, a machine tail part, a chute, an accessory and a push unit, and is characterized in that coal shoveling plates which can bidirectionally push the conveyor to shovel coal are arranged at the two sides of the conveyor; and a component which is connected with the push unit and can be used for bidirectionally pushing the conveyor is arranged on the conveyor. By adopting the structure, the pushing direction of the conveyor does not push toward the direction of the coal wall along a bottom plate like a long wall coal mining working face but pushes toward the direction of a top plate or a bottom plate along the coal wall. The coal wall with various shapes and gradients can be artificially made according to requirements under the feet of operators, so that the feel like standing upon the edge of an abyss in the steep dip long wall working face is eliminated, and the problem that coal briquettes fly swiftly downwards in the working face with the gradient of 60 degrees or more and hurt people is completely solved to ensure that multi-point parallel operation becomes possible.

Description

technical field [0001] The utility model relates to a conveyor used for vertical seam coal mining face in underground coal mine. Background technique [0002] At present, the transportation equipment used in the coal mining face of the coal mine mainly includes scraper conveyors and enamel chutes that are not conveyors. [0003] The scraper conveyor used for coal mining is mainly used in the longwall coal mining face. It is arranged in the cutting eye along the inclination, falls on the bottom plate of the coal seam, and advances along the bottom plate to the direction of the coal wall. Generally speaking, the maximum inclination angle of the upward transportation of the scraper conveyor shall not exceed 25 degrees, and the downward transportation shall not exceed 20 degrees. Although it is also used in the working face with a larger inclination angle, it seldom exceeds 45 degrees. This is because it is difficult to solve the anti-skid problem of the equipment after the inc...

AI Technical Summary

Problems solved by technology

[0005] For steeply inclined thick coal seams, people generally adopt the method of caving top coal horizontally, but steeply inclined coal seams with a thickness of less than 5 meters have to be mined with the ancient high-drop coal mining method with a history of hundreds of years. Low, because it is mainly operated by hand, it is labor-intensive, and some thinner steeply inclined coal seams are even simply classified as unminable coal seams and discarded
