Fully mechanized coal mining face hydraulic support side guard plate dust falling guide and moving device

Abstract

The invention relates to the technical field of coal mine fully mechanized coal mining face dust control devices, and particularly relates to a fully mechanized coal mining face hydraulic support sideguard plate dust falling guide and moving device. The fully mechanized coal mining face hydraulic support side guard plate dust falling guide and moving device comprises a first mounting seat, a telescopic part, a connecting part, a dust receiving groove and a second mounting seat, wherein the first mounting seat and the second mounting seat are both fixedly arranged; one end of the telescopic part is hinged to the first mounting seat, and the other end of the telescopic part is hinged to the connecting part; the connecting part is fixed to the side face of the dust receiving groove; the second mounting seat is hinged to a groove opening of the dust receiving groove; and the first mounting seat and the second mounting seat are fixed to a side guard plate of a hydraulic support, dust fallsonto the dust receiving groove, the dust slides to a low-position area behind a working face through the dust receiving groove, the situation that the dust is directly scattered to a support pedestrian crossing area is avoided, the influence of the dust on the body health of workers is reduced, the working environment of the workers is effectively improved, and the dust falling effect is improved.

Description

technical field [0001] The invention relates to the technical field of a dust control device for a fully mechanized mining face, in particular to a dust falling guiding device for a hydraulic support side guard plate of a fully mechanized mining face. Background technique [0002] The fully mechanized mining face is the hardest-hit area of ​​dust pollution. Working in an environment with high concentration of dust for a long time greatly increases the risk of miners suffering from pneumoconiosis. According to relevant studies, more than 80% of the dust in the working area of ​​personnel working in fully-mechanized mining faces with large mining heights comes from the dust generated by frame removal. The dust spilled from the gap between the side guard plates of two adjacent supports to the sidewalk, and spread rapidly under the action of wind current, which seriously deteriorated the working environment of the workers in the fully mechanized mining face. [0003] At present...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to: in view of the prior art, during the forward movement of the hydraulic supports, the dust on the top is easy to fall from the gap between the hydraulic supports, and the single way of dust reduction by spraying will affect the work of the staff and deteriorate the working environment Or due to the problem that it is impossible to install a closed dust guide device due to space constraints, a dust guide device for the side guard plate of the hydraulic support of the fully mechanized mining face is provided.
