Create a receiving space 40 in the guide part of the
Complete the cycle. Subsequent rod addition is performed by repeating the mechanized mounting and the mechanized alignment or the non-mechanized alignment described above.

To disengage the rod 7 from the boring machine 1,
First, the rod 7 to be detached is pulled up to the guide portion 4 of the boring machine 1 and released from the connection with the preceding rod 7 and the drive portion 5. Next, the front transmission / reception jack 12 _f2 and the rear transmission / reception jack 12 _r2 are shortened as compared with the lengths of the front inclination jack 12 _f1 and the rear inclination jack 12 _r1 , and the rack 15 is drilled as shown in FIG. 4 (C). Tilt down from the excavation axis 16 of the machine 1 (β <0
(Eg, -5 °). The leading rod 7 and the rod 7 released from the drive unit 5 in the guide unit 5 are transferred to the rack 15 as shown in FIG.
It is also possible to manually disengage as shown by arrow R in FIG. For this detachment, the rod 7 can be detached by manually applying a force toward the rack 15 to the rod 7 as shown by an arrow S in FIG. 4 (C) with a hammer or the like. Therefore, the rod 7 can be mechanically disengaged without manual transportation. If the receiving portion 8 that can be swung by the swing shaft 20 described below with reference to FIG. Can be all mechanized.

Thus, the object of the present invention is to provide a "drilling machine with a rod attaching / detaching device capable of mechanizing the handling and alignment of the rod".
