摘要： An external water delivery system includes a water box front head, a collet configured to interface with the water box front head, a polymer sleeve configured to be positioned between the water box front head and the collet, a shank, and at least one seal positioned within the sleeve. The sleeve and seals are configured to provide a water chamber when coupled to the shank. An inner of the sleeve provides a bearing surface for the shank.

摘要： Pneumatic drifters containing a drifter cylinder with removable feet and associated methods for using the pneumatic drifters are described. The removable feet are connected to feet pad of a drifter cylinder with multiple fasteners. The mating surfaces of the feet and the feet pad are provided with complimentary features that limit the shearing forces on the fasteners during operation of the drifter rock drill. The removable feet can be replaced quickly and easily without have to replace the entire drifter cylinder, thereby saving time and reducing costs. Other embodiments are also described.
