Abstract
A ballast cleaning machine comprises a machine frame supported on the track by undercarriages for movement in an operating direction. Two vertically and laterally adjustable endless ballast excavating chains are sequentially arranged in a longitudinal direction for excavating ballast from the ballast bed, and a track lifting device mounted on the machine frame. A first conveyor arrangement conveys the ballast excavated by the first endless ballast excavating chain to a first screening installation, a second conveyor arrangement conveys the ballast excavated by the second endless ballast excavating chain to a second screening installation, and a third conveyor arrangement distributes the cleaned ballast to the ballast bed.
Claims5
A ballast cleaning machine for cleaning a ballast bed supporting a track, which comprises
- (a) a machine frame extending in a longitudinal direction and supported on the track by undercarriages for movement in an operating direction,
- (b) two vertically and laterally adjustable endless ballast excavating chains sequentially arranged in the longitudinal direction for excavating ballast from the ballast bed, a first one of the endless ballast excavating chains leading a second one of the endless ballast excavating chains in the operating direction,
- (c) a track lifting device mounted on the machine frame,
- (d) a first screening installation for cleaning ballast,
- (e) a second screening installation for cleaning ballast,
- (f) a first conveyor arrangement for conveying the ballast excavated by the first endless ballast excavating chain to the first screening installation, the first conveyor arrangement having an input end arranged to receive the excavated ballast from the first endless ballast excavating chain and an output end arranged to discharge the conveyed excavated ballast into the first screening installation,
- (g) a second conveyor arrangement for conveying the ballast excavated by the second endless ballast excavating chain to the second screening installation, the second conveyor arrangement having an input end arranged to receive the excavated ballast from the second endless ballast excavating chain and an output end arranged to discharge the conveyed excavated ballast into the second screening installation, and
- (h) a third conveyor arrangement for distributing the cleaned ballast to the ballast bed.
