Abstract
A gutter broom (8) for a pavement sweeper is defined by an annular brush disc (24) having a central opening and from which a series of equi-spaced conventional bristle blocks (11) are removably secured. A downwardly depending air foil (18) is secured to the underside of the annular brush disc (24) between each bristle block (11). A series of equi-spaced radially aligned fan blades (17) are secured to the opposite side of the annular brush disc (24) and function to define a radial flow fan. A stationary fan scroll (20) is formed over and contains the radial flow fan and includes an air flow outlet (23). When the gutter broom (8) is rotated, the air foils (18) function to draw ambient air and any entrained dust/debris into the brush structure with the resultant air streams directed to the radial fan structure, which, in turn, directs the dust/debris laden air stream to the outlet (23).
