Scraper conveyor and operation method thereof

Abstract

The invention discloses a scraper conveyor and an operation method thereof. The scraper conveyor comprises an overall framework, a falling coal conveying component and a follow-up falling coal guidingcomponent; the falling coal conveying component is installed on the overall framework and can convey a coal on the surface of the overall framework; the follow-up falling coal guiding component is installed on one side of the overall framework; and a crushing assembly moves with the movement of a coal cutting machine, a coal layer cut by the coal cutting machine is enabled to fall onto the surface of the overall framework via the crushing assembly. The scraper conveyor can easily advance towards to the coal layer and can always maintain a horizontal status, so it can be ensured that all coals cut by the coal cutting machine fall onto the scraper conveyor. The scraper conveyor disclosed is durable.

Description

technical field [0001] The invention relates to the technical field of scraper conveyors, in particular to a chain scraper conveyor used for transporting coal in fully mechanized mining working faces. Background technique [0002] The scraper conveyor is an indispensable main equipment in the modern coal mining process. It not only transports coal and materials, but also serves as the running track of the coal cutter. During the coal mining process of the fully mechanized mining face, the coal cutter mines coal along the scraper conveyor. After coal mining, there is a goaf, and the chute of the scraper conveyor is a certain distance from the coal seam. push to the coal seam. The bottom surface of the current scraper conveyor is in direct contact with the ground, which makes it very difficult to push the chute of the scraper conveyor to the coal seam; due to the unevenness of the ground in the goaf, the scraper conveyor often tilts, and in severe cases it will Rollover occu...

AI Technical Summary

Problems solved by technology

The bottom surface of the current scraper conveyor is in direct contact with the ground, which makes it very difficult to push the chute of the scraper conveyor to the coal seam; due to the unevenness of the ground in the goaf, the scraper conveyor often tilts, and in severe cases it will Rollover occurs; the coal cut by the coal cutter falls directly on the scraper conveyor, and when some larger coal falls, it is easy to damage the scraper conveyor; when the coal seam is soft, when the coal cutter cuts the coal seam, it will A large area of ​​coal seam is cut off, which will cause part of the cut coal seam to fall outside the chute of the scraper conveyor, resulting in great waste
