초록 ▼

A vacuum sweeper vehicle including a hopper mounted to the vacuum truck chassis, a vacuum system for drawing a predetermined partial vacuum at a vacuum inlet and a suspended vacuum sweeper head having a debris conduit leading to a debris outlet. The hopper has a seamless fiberglass tank formed with a front wall having a vacuum outlet for mating with the vacuum inlet and a debris inlet for mating with the debris outlet. The tank has top and bottom walls and is formed with pairs of laterally disposed respective upper and lower longitudinally extending rounded corners formed integrally between laterally disposed side walls. The rear end of the tank is open to form a debris removal outlet and a rear door is hingedly connected to the rear of the tank to be disposed in closing relation over the rear of the tank. In addition, the tank includes a screen and a diverter interposed between the debris inlet and vacuum outlet that cooperate to direct air flow from the debris inlet through the screen to the vacuum outlet.

A hopper for mounting to a vacuum truck chassis including a vacuum system for drawing a predetermined partial vacuum at a vacuum fan inlet and having a suspended vacuum sweeper head including a debris conduit leading to a debris outlet, said hopper comprising: a hopper tank formed with a front wall having a vacuum outlet for mating with said vacuum fan inlet and a debris inlet for mating with said debris outlet, a peripheral wall formed with pairs of laterally disposed respective upper and lower longitudinally extending rounded corners formed integrally between respective laterally disposed side walls and respective top and bottom walls; said tank terminating at its back end in a sealing flange configured to form a debris removal outlet; a screen partition interposed between said debris inlet and vacuum outlet and including a screen spaced from said top wall and cooperating with said peripheral wall to form therebelow a debris collection chamber and thereabove a return plenum chamber extending to said vacuum outlet; a diverter interposed between said debris inlet and said vacuum outlet and extending from said front wall to said screen to direct air flow from said debris inlet to said vacuum outlet; a rear door hingedly connected to the rear of said tank to be disposed in closing relation over the back of said tank; and a peripheral gasket on said door for sealing engagement with said sealing flange whereby when said door is closed and said vacuum outlet and said debris inlet are mated with said respective vacuum inlet and debris outlet and said vacuum system operated to draw said partial vacuum, debris suspended in air drawn through said vacuum head through said conduit into said debris inlet will be swept along rearwardly in said tank along said bottom wall and respective lower bottom corners to be drawn upwardly to said screen allowing the debris to fall downwardly in said tank and, as said air is drawn upwardly through said screen, removing the remaining debris out of said air to cause the filtered air to flow forwardly in said return plenum along said top wall and said laterally disposed top corners to then be drawn into said vacuum outlet.
