Abstract: A drill pipe carousel is pivotal within a drilling mast between retracted and operating positions. The carousel contains a plurality of drill pipe receptacles for holding sections of drill pipe. Each of these drill pipe receptacles includes an upper and lower set of clamps that selectively clamp around a section of drill pipe within the receptacle to retain it in place, and open to release the pipe section. In the carousel operating position, a section of drill pipe is in alignment with the drill hole and a rotary head mounted on the drilling mast for linear movement along the mast. The rotary head attaches to this drill pipe section and rotates it to drill into the drill hole as the rotary head moves along the mast.
