Abstract

The invention relates to a coal cutter secondary negative pressure dust fall device, and belongs to the technical field of coal cutter dust fall equipment. The coal cutter secondary negative pressuredust fall device is mainly used for solving the technical problem that a dust fall device in the prior art is low in dust removal efficiency, and cannot be assembled or disassembled flexibly. According to the technical scheme, the coal cutter secondary negative pressure dust fall device comprises a support, an ejection barrel assembly and a magnetic sucking disk. The support comprises a support base plate and a support side plate. The support side plate is arranged on the top side of the support base plate. The ejection barrel assembly is arranged above the support base plate. The bottom of the ejection barrel assembly is connected with the support base plate through adjusting bolts. The magnetic sucking disk is arranged on the outer side of the support side plate and is connected with thesupport side plate through long bolts. The ejection barrel assembly comprises an ejection barrel support, an ejection barrel and a nozzle. The coal cutter secondary negative pressure dust fall devicehas the advantages of being high in dust removal efficiency, flexible and convenient to disassemble, and the like.

Description

technical field [0001] The invention belongs to the technical field of dust suppression equipment for coal shearers, and in particular relates to a secondary negative pressure dust suppression device for coal shearers. Background technique [0002] The continuous improvement of comprehensive mechanized coal mining in coal mines has not only brought huge economic benefits, but also caused many negative effects. The biggest problem is the generation of high-concentration coal dust, which seriously affects the safe and efficient production of mines. Threat to the health of personnel. According to relevant data, the dust suppression efficiency of ordinary spray dust suppression systems is only 40% to 50%, and the dust that has not been settled is easy to float with the wind, polluting the working environment, and the installation and disassembly of the existing dust suppression devices on the coal mining machine is not flexible, which consumes manpower physical resources. Con...
