More Information
Summary:The present invention relates to a multi-core barrel hammer system rapidly discharging a crushed object to maximize work efficiency and enabling excavation of a large caliber at once. Therefore, the present invention comprises: a hammer bit having a bit body; a roller bit installed in a rotor; and a suction discharge pipe. The suction discharge pipe is formed to be adjacent to the bit body and enables the crushed object crushed by the bit body to rapidly be discharged to the suction discharge pipe to improve crushing efficiency, and is capable of discharging the crushed object discharged through a crushed object flow passage formed in the bit body and the crushed object crushed by an auger.
