ABSTRACT:
A drill rod feeding device which stores drilling rods and sorts them before placing them into hands with a hydraulic lock. These hands, when loaded and locked, pivot and position the rods into the axis of a drilling head, maintaining them in position to screw them. When this operation is completed, the hands unlock and continue their course toward a waiting position located at 180.degree. from their starting point upward to allow the movement of the drilling head. The opposite takes place when the rods have to be withdrawn, that is waiting at +180.degree., movement to the drilling axis, locking, unscrewing of the rod of the drilling head, downward to less 180.degree., unlocking, capture by a sorter-positioner and storage.
