摘要： A dust abatement vacuum hood, provided for a flush-cutting concrete saw, includes a rigid shell that is preferably either vacuum formed or injection molded from a tough polymeric material that may be reinforced with structural fibers. Alternatively, the vacuum hood may be stamped or cast from a durable metal. The vacuum hood is equipped with a vacuum port to which one end of a vacuum hose may be attached. The opposite end of the vacuum hose is attached to a vacuum cleaner system. The vacuum hood has a spring-mounted attachment bracket that can be bolted directly to the concrete saw. As the blade of the concrete saw rotates, pulverized concrete is discharged into a chamber opening of the vacuum hood. Internally, the vacuum hood is shaped so that the pulverized concrete is directed toward the vacuum port, from where it is directed to the vacuum cleaner system.
