ABSTRACT:
A feed storage for drill rods for a long-hole drilling apparatus, said feed storage comprising a magazine provided with fixed guides (11) for storing drill rods (13) in parallel with each other, a delivery opening (14) defined by the guides for transferring drill rods one at a time into and out of the guides, and a feed device provided with gripping means (27) extending between the drill rods positioned in the guides for feeding the drill rods towards and away from the delivery opening in the guides, and a transfer device (9) comprising at least one transfer arm (29) provided with gripping jaws (31) and pivotably mounted on a pivot shaft (30) which is fixed with respect to the magazine so that the gripping jaws are displaced transversally with respect to the axial direction of the drill rods between the delivery opening of the guides and the drilling axis (A) of a drilling machine. The guides of the magazine guide the drill rods with their axes in the same plane. The feed device comprises two feed plates carrying out movements in opposite directions. The transfer arm is pivoted so that the gripping jaws are displaced along a circular arc between the delivery opening and the drilling axis.
