Abstract
A suction unit (76) provided with a suction pipe (80) having a suction opening (81) for sucking off crushed rock and being vertically and laterally adjustable is allocated to a machine (57) for treating the ballast bed of a track (60) with a machine frame (58) supported on rail travelling undercarriges (59). In addition, there is provided a clearing apparatus (62) disposed at a distance from the suction opening (81) in the longitudinal direction of the machine and provided with an endless clearing chain (64) rotatable by a drive (63) for removing the crushed rock disposed below the track (60). Like the suction pipe (80), it is provided with separate drives (82, 99) for vertical and lateral adjustment independently from one another.
