  • DRILL ROD GUARD AND SYSTEMS AND METHODS OF USING SAME
    Publication number: 20160032689
    Abstract: A drill rod guard having a feed shaft assembly that supports a feed shell for receiving a drill rod. First and second shafts are respectively pivotally coupled to opposed sides of the feed shaft assembly. A plurality of guard elements are operatively coupled to the first and second shafts, and opposed guard elements are selectively engageable with one another. Upon engagement between the opposed guard elements, the guard elements cooperate with the feed shell and/or the feed shaft assembly to substantially enclose the portion of the drill rod within the feed shell to thereby prevent contact with the drill rod.
