Abstract (en)
[origin: US5742967A] Sweeping devices for utility vehicles with a rotatingly driven bristle roller have been known, which are covered on the top side by a protective housing and in front of which a feed screw extending in parallel to the bristle roller is arranged, and the feed screw is arranged, drivable by a motor, in a sweepings collection housing, which is provided with a rear charging opening and with a discharge opening at the end of the screw, wherein the sweepings collection housing has an obliquely downwardly directed baffle plate with a flexible bottom plate under its charging opening. To improve the mode of operation and the sweeping performance, especially at higher speeds of travel, the bristle roller is driven at such a speed of rotation that in the area located between it and the charging opening of the sweepings collection housing, it generates an air flow, which continues into the discharge opening of the sweepings collection housing, which is designed as a feed cup and a flow channel at the same time.
