Abstract: A core tube handling device can be used with exploratory drilling rigs. The device can include a slew arm mounted on the rig's mast and a pivot arm mounted on the slew arm. When the slew arm is adjacent to the mast, clamping devices on the pivot arm can grasp and hold a core tube from the drill string. The slew arm can pivot away from the mast and align the pivot arm with a tray that receives and holds the tubes. The pivot arm can pivot to a position proximate the tray and release the tube. The tray can be rotatable and translatable to facilitate transfer of the tube from the pivot arm to the tray.

Abstract: A high pressure injection flushing head includes a flushing body comprising an upper body portion, and a lower body portion coupled to the upper body portion. The upper body portion and the lower body portion cooperate to define a bore. A shaft is rotatably disposed at least partially within the bore. A plurality of rotary elements are configured to facilitate rotational movement of the shaft relative to the flushing body. The flushing body comprises a lubrication system having a plurality of grease nipples, and a network of pathways in fluid communication with the grease nipples that are configured to deliver grease to the rotary bearings. The flushing head couples to an adapter via a flanged connection so that the flushing head can be adapted for use with a plurality of drill rod types.
