With the continuous expansion of the construction market, the traditional manual drilling and blasting has gradually withdrawn from the application market, and the drilling jumbo has begun to show itself. Because the traditional inclined hole cutting drilling method has high requirements for the

In order to reduce the dust pollution produced by the down-hole drill in the working process, the dust removal system of the down -hole drill is designed. The working principle and composition of the dust removal system are introduced. The dust collection cover, cyclone dust collector, dust removal
