A bolt-drilling-unit device, having a bolt drive-in device designed to drive a rock bolt into a drill hole in rock. The bolt drive-in device comprises a bolt-securing device 114-150, which can be propelled on a feed beam 44 on a slide 112, and a bolt magazine 80, 110 for a plurality of rock bolts. A control mechanism 64, 66, 70, 72 connecting the bolt magazine 80, 110 to the feed beam 44 is designed to swing the bolt magazine 80, 110 into a position in which one of its bolts, situated in a feed- out position, can be directly clamped in the bolt- securing device 114-150. The bolt magazine then immediately advances a new bolt into the feed-out position. <IMAGE> |
