摘要

A rock drilling, swelling and chiselling integrated machine is provided,comprising: a rock drilling, swelling and chiselling integrated machinemechanicalapparatus, a high-pressure foam generating and conveying system, and a holesealingapparatus. The rock drilling, swelling and chiselling integrated machinecomprises apower apparatus, an impact piston, a motor, a driving gear group, an impact-rotarydrill bit, a drill pipe, a drill hole sealing apparatus, a high-pressure foamconveyingchamber, and a high-pressure foam generating and conveying system. Thehigh-pressure foam generating and conveying system comprises a liquid pump, agaspump, a liquid-gas mixer, and a pressurizer, and can adjust a liquid-gasmixingproportion and conveying pressure according to different rock hardness degreesandworking conditions.
