摘要： PURPOSE: A rod unit for a direct-boring device is provided to prevent air pollution occurred by scattered dust, and to improve workability and boring efficiency. CONSTITUTION: A rod unit(10) for a direct-boring device comprises a head member, a first connecting rod, a hammer unit(30), a second connecting rod, and a dust guide discharging unit. The head member is coupled to a motor(240) for supplying torque. The first connecting rod is formed to transfer torque from the head member and the motor. The hammer unit is installed in the end of the first connecting rod. The second connecting rod connects the head member and the hammer unit, and covers the first connecting rod. The dust guide discharging unit discharges dust occurred when drilling.
