Abstract

The invention provides a dust removing curtain device for a development machine, and belongs to the field of engineering machinery. The device comprises a curtain, a positive pressure wind cylinder, a negative pressure wind cylinder, and a dust removing fan and a dust remover sequentially connected with the negative pressure wind cylinder. The curtain is arranged on a development machine body and divides a development roadway into two parts, the positive pressure wind cylinder and the negative pressure wind cylinder are respectively arranged on two sides of the curtain, and the operating compartment of the development machine is arranged on the side where the positive pressure wind cylinder is positioned. The development roadway is divided into two parts by adopting the curtain device; the purpose of removing dust in the roadway is fulfilled by using circulating airflow formed by the positive pressure wind cylinder and the negative pressure wind cylinder; and meanwhile, because an operator is positioned at the side of the positive pressure wind cylinder, the operator is isolated from dust, the working environment of a development worker is improved and the physical and psychological health of the development worker is ensured.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a dust removal curtain device for a roadheader. Background technique [0002] With the continuous improvement of the mechanization level of coal mines, the production of mine dust is increasing. According to the actual measurement, the dust concentration generated by the roadheader cutting is as high as 1000-3000mg / m3, of which the respirable dust with a particle size of less than 7μm accounts for more than 85% , seriously endangering the physical and mental health of on-site staff. At present, there are many types of dust removal equipment in China, but the dust removal effect is not good. In addition to the dust removal efficiency of the dust collector, the layout of the ventilation and dust removal system is more important. When most ventilation and dust removal systems are arranged, the pressed fresh air is blown to the excavation surface, and the dust generated by the ...
