本发明是一种带有除尘装置的液压支,架。 这种液压支架的除尘装置由装在支架并直接对着两个相邻支架间的间隙的喷咀构成,以便清除从顶板和采空区落入该间隙的煤尘。 这种除尘装置的缺点是,除尘只能在煤尘聚积较多的开采巷道内进行,所以有些煤尘可能通过裂隙和裂缝被吹入液压支架内,并会带来很大麻烦。 本发明介绍的也是带有除尘装置的液压支架,其除尘装置能在产生煤尘的地点进行除尘。 The present invention is a hydraulic branch with a dust removal device. The dust removal device for such a hydraulic support consists of a nozzle mounted on the support and directly facing the gap between two adjacent supports to remove dust falling into the gap from the ceiling and the goaf. The disadvantage of this dedusting device is that dedusting can only be carried out in the mining roadway where the accumulation of coal dust is high. Therefore, some coal dust may be blown into the hydraulic support through the cracks and cracks, which will cause great inconvenience. The present invention also introduces a hydraulic support with a dedusting device whose dedusting device is capable of dedusting at a location where coal dust is generated.
