Abstract
The present invention relates to a device for setting rock bolts. The device employs a common element for affixing the end of a feed shell with respect to a rock surface, stabilizing the feed shell and providing a common centralizer for centering all subsequent bolt setting operations. The device also has a bolt delivery system which stores, advances and positions the bolts in line with a bolt driver. The bolt delivery system has a bolt magazine which, when in a work position, advances bolts along peripheral surfaces into a position where they are engaged by a bolt driver. The bolt so engaged is then advanced into the centralizer at which point the bolt magazine is rotated away from the engaged bolt to a park position where it will not interfere with the bolt driver as it continues to advance the bolt. The bolt magazine preferably also serves as a bolt plate magazine which accommodates bolt plates with which the bolts are engaged. The bolt plates are stabilized by a bolt plate channel having an opening through which the bolt plates can exit the magazine.
