Scraper conveyor for cross side discharge arrangement of gently inclined coal seam

Abstract

The invention discloses a scraper conveyor used in a cross-side discharge arrangement for gently inclined coal seams, relates to the technical field of fully mechanized mining equipment in coal mines, and aims to make the cross-side discharge arrangement suitable for fully-mechanized mining of gently inclined coal seams. The scraper conveyor includes a chute, and the chute includes a plurality of first troughs, second troughs and third troughs; the first trough and the second trough have the same width and are respectively half the width of the third trough; The number of the two is the same, and the total width of the three is the same; the height and length of the two sides of each first tank body and the second tank body respectively decrease in an arithmetic sequence from the direction of the nose to the tail; The structure and size of the three tanks are the same, and the structures and sizes of the first tanks and the second tanks at the corresponding positions in the plurality of first tanks and the plurality of second tanks are respectively the same, which is the same as that of the third tank. The height and length of both sides of the body adjacent to the first groove body and the second groove body are respectively the same as the height and length of both sides of the third groove body.

Description

technical field [0001] The invention relates to the technical field of fully mechanized mining equipment in coal mines, in particular to a scraper conveyor used in a cross-side discharge arrangement for gently inclined coal seams. Background technique [0002] The cross-side unloading arrangement of the scraper conveyor can reduce the unloading height, provide convenience for the end support and cut through the triangular coal, can eliminate the unloading obstacle of lump coal, improve the transportation capacity of the scraper conveyor, and can also slow down the coal flow to the loader Especially when the inclination angle of the working face is large, once the working face goes up and down, the unloading distance remains unchanged, which can improve work efficiency and safety factor. [0003] However, the current cross-side unloading arrangement of scraper conveyors is only suitable for fully mechanized mining in near-horizontal coal seams. The arrangement of scraper conv...

AI Technical Summary

Problems solved by technology

[0003] However, the current cross-side unloading arrangement of scraper conveyors is only suitable for fully mechanized mining in near-horizontal coal seams. The arrangement of scraper conveyors in gently inclined coal seams is still an end-unloading arrangement. This arrangement has a large unloading height. The coal flow is directly unloaded onto the transfer machine vertically, which has a greater impact on the transfer machine

Moreover, it is easy to have problems such as insufficient lap joints or too long lap joints during use, resulting in poor coal unloading and coal accumulation, especially when the working face goes up and down, the unloading distance is unstable, which reduces work efficiency and safety factor
