牙轮钻机是以牙轮钻头、稳杆器、牙轮钻杆及补偿杆组装成一体作为穿孔器具,并采用压气排渣的自行式钻孔机械。稳杆器的功能是将牙轮钻头未来得及凿碎的矿石进一歩压碎,并将孔壁进一歩压实与扩充,保证孔径与钻头一样大,避免钻杆被岩渣掩埋。 Tricone is a roller cone drill bit, stabilizer rod, cone drill rod and compensation rod assembly as a whole as perforation equipment, and use of self-drilling gas pressure slag drilling machine. The function of the stabilizer bar is to crush the roller bit in the near future and to further compact and enlarge the hole wall to ensure that the hole diameter is the same as that of the drill bit so as to prevent the drill pipe from burying the rock residue.
