ABSTRACT:
A railroad ballast sweeper controls dust by use of a double segmented skirt arrangement. Segments of elastic, flexible material extend downwardly from a housing in which a rotary broom is disposed. The skirts prevent leakage of dust-laden air out from the housing. Further, a fan and associated filters are used to draw air out from within the housing, thus creating a slight negative pressure within the housing. A grate having a series of metallic strip grate elements is used to block dust from reaching the filters. The grate elements force air to turn up abruptly in order to get to the filters, whereas the dust, by virtue of its higher mass, is generally unable to make a sufficiently quick change in direction in order to reach the filters. The grate has an orientator to insure that, upon replacing the grate, any new grate will necessarily be inserted with the proper orientation. In order to prevent air and particles propelled by the broom elements of the broom from opening the skirts and allowing dust-laden air to escape, a metallic break-up deflector strip or member is mounted adjacent the periphery of movement of outer tips of the broom elements.
