摘要:
A resin nozzle positioner for a rock bolter, having a frame supporting feed tracks traversed by a drill and a bolt driver, has a resin nozzle that guides a resin sausage into a hole drilled along a work axis. A positioner base is fixed to the frame and two arms are pivotably connected to the positioner base and to a nozzle block, to which the resin nozzle is mounted. The arms remain parallel and move such that the resin nozzle remains parallel to the work axis while moving along an arc between a retracted position, where the resin nozzle is spaced apart from the work axis, and an extended position, where the resin nozzle is aligned with the work axis. An actuator operably connected to two elements selected from the arms, the positioner base, and the nozzle block serves to move the resin nozzle.
