大型挖掘机是露天采掘设备,特别是在深凹露天矿采场工作时,粉尘严重,致使司机室内粉尘浓度超过国家卫生标准。若不采取相应的防尘措施,将严重危害工人身体健康,矽肺病已成为司机的职业病之一。同时,司机室内夏天炎热,冬天寒冷,为改善司机的工作环境进一步提高生产率,研制空调除尘装置已成为当务之急。挖掘机的一些重要机械部件和电气设备都布置在机棚内,机棚除防风防雨外,还应具有防尘、保温性能。为保持机棚内空气清洁,国 Large excavators are open pit mining equipment, especially in deep open pit mining work, the dust serious, resulting in the driver indoor dust concentration exceeds the national health standards. If you do not take the appropriate dust control measures, will seriously endanger the health of workers, silicosis has become one of the driver’s occupational diseases. In the meantime, the drivers are hot in summer and cold in winter. In order to improve the driver’s working environment and further enhance the productivity, the development of air-conditioner dust-removing devices has become a top priority. Excavator some of the important mechanical components and electrical equipment are arranged in the hangar, hangar in addition to wind and rain, but also with dust, heat preservation performance. To keep the air inside the shed clean, country
