Abstract
A linkage assembly for a drilling machine includes a first arm, a second arm, an actuation member, and a connector assembly. A first end of the first arm is pivotally coupled to a positioning member at a first pivot joint. A first end of the second arm is pivotally coupled to a feed table at a second pivot joint. A first end of the actuation member is pivotally coupled to the feed table at a third pivot joint. The connector assembly is fixedly coupled to a second end of the first arm, and pivotally coupled to a second end of the second arm and a second end of the actuation member. The linkage assembly is adapted to pivot the feed table relative to the positioning member about a pivot axis based on movement of the actuation member between an extended position and a retracted position.
