Abstract

A machine for treating a ballast bed underneath a track comprises a machine frame extending in a longitudinal direction and supported on the track by undercarriages for movement in an operating direction, a suction unit mounted on the machine frame, the suction unit comprising a vertically and laterally adjustable suction pipe having a suction opening for aspirating ballast from the ballast bed, a conveyor band arranged on the machine frame to convey the aspirated ballast away from the suction unit, and a ballast discharge device mounted on the machine frame rearwardly of the suction pipe in the operating direction, the ballast discharge device comprising a hopper. A conveyor arrangement extends in the longitudinal direction on the machine frame and has an input end arranged to receive the aspirated ballast from the conveyor band and an output end arranged to discharge the aspirated ballast into the hopper. A track lifting unit is mounted on the machine frame between the suction opening and the ballast discharge device.
