Description

DUST CONTROL HOOD AND DUST CONTROL SYSTEM ABSTRACT OF THE DISCLOSURE This dust control system is mounted on a drill tower. A housing with an open bottom is used for drawing air into the housing. A side air outlet is used for drawing the dust and chips from the housing to a skimmer. The housing is provided with a pair of longitudinally separated flexible seals with central holes adapted to flexibly receive the drill bit and drill string. The dust hood is movable longitudinally with respect to the drill tower so that the dust hood may be adjusted to a predetermined height above the top of the hole. The hood may be swung from a position aligned with the drill bit and drill string to a position laterally spaced from the side of the drill tower and vice-versa.
