Abstract
A drive-through adjustable hood assembly for enclosing a transit mix cement truck during the filling of dry material so as to contain and capture dust and particulate matter. The adjustable hood assembly is mounted on an expanding and retracting frame system. Entrance and exhaust ports are provided in the hood so that a truck can be filled and the resulting dust removed to prevent contamination of the atmosphere. A clam shell type enclosure is thus provided which in the extended open position allows unobstructed access into the adjustable hood assembly and in the retracted closed position provides intimate wrap-around enclosure of the cement truck during filling and dust removal operations. The width of the assembly in the extended open position can be varied by making minor mechanical adjustments to the frame system.
