ABSTRACT:
Disclosed is a rotary broom hopper which includes a container having a bottom wall, a front wall, a rear wall, and a top wall. A dust and debris inlet is positioned between the bottom wall and the rear wall and a filter element is positioned between the rear wall and the top wall. A first interior wall extends into the container from the rear wall between the inlet and the filter element. A second interior wall is positioned between the first interior wall and the filter element such that the first and second interior walls form a secondary material separation chamber interior of the container. An impingement plate is positioned to extend perpendicular to the top wall into the secondary material separation chamber. The impingement panel causes an abrupt reversal of direction of air flow and deposits a substantial quantity of particulate matter in the secondary material separation chamber and thereby reduces the accumulation of such material on the filter element.
