Abstract

A ballast broom machine for sweeping ballast off a track comprises an elongated machine frame supported on the track by undercarriages, and at least three ballast brooms vertically adjustably mounted on the machine frame, the ballast brooms being spaced from each other in the longitudinal direction and including a leading ballast broom, each ballast broom comprising a rotary shaft extending perpendicularly to the longitudinal direction and flexible sweeping elements projecting radially from the rotary shaft. A conveyor band is mounted on the machine frame and extends in the longitudinal direction, the conveyor band having an input end arranged to receive ballast swept off the track by the leading ballast broom and a discharge end positioned higher than the input end, and a ballast storage bin having discharge openings is arranged on the machine frame below the conveyor band discharge end for receiving discharged ballast therefrom. A ballast conveyor band is mounted on the machine frame immediately preceding each ballast broom and extends transversely to the longitudinal direction.
