Abstract: PURPOSE: To easily mount drill tubes and/or rods with slight inputs without drilling by positioning between the retainer of a feed beam and a rotating motor a breaking device rotatable in the cross direction of the feed beam. CONSTITUTION: A drilling machine 4 is placed on a feed beam 3 and a rotating motor 5 is mounted in front of it. Also, a retainer 6 is provided at the front end of the beam 3 and a breaking device 7 provided with pressure cylinders 12a, 12b or the like with a clamping jaw 14a or the like is positioned between the retainer 6 and the motor 5. The breaking device 7 is rotated in the cross direction of the beam 3 for insertion of a new tube 9b through an opening 15 and the pressure cylinders 12a, 12b are positioned to press the tube 8b. Further, the breaking device 7 and the beam 3 are rotated in parallel relation and the tube 8b is moved in such a way as to be fastened to an existing tube 8a and is mounted as it is screwed up by the motor 5 and the drilling machine 4.
