Adjustments according to the YZ axis coordinate system can be performed without any restrictions.

By constructing the support structure as claimed in claim 4, the guide and adaptation of the suction nozzle to obstacles which must be bypassed at the time of sucking will be further improved. By tilting the suction nozzle by means of a rotary drive, it is possible to suck up the ballast in the area under the sleepers in a targeted manner.

A particular advantage provided by the embodiment of the suction machine according to claim 5 is that both ballast reservoirs can be discharged alternately while achieving a continuous suction action.

Further, according to the embodiment described in claim 6, it becomes possible to efficiently carry out the sucked ballast to the succeeding ballast loading freight car. By allowing the transport drive to be loaded selectively in both rotation directions,
The sucked ballast can be discharged to the track bed again via the transshipment belt conveyor if necessary.

It can be switched automatically. The discharge of both dust removing chambers 20 is performed via the belt conveyor 22 and the transshipment belt conveyor 26, similarly to the discharge of the ballast storage tanks 17 and 18.

If ballast that has been evacuated and optionally cleaned on the basis of dust removal of the suction air is required for installation in the track bed section,
The transfer belt conveyor 26 is shifted by the drive device 30 to the transfer conversion position indicated by the chain line. In parallel with this operation, the transfer drive device 31 is biased in the opposite direction, so that the ballast discharged from the ballast storage tanks 17 and 18 to the belt conveyor 22 travels from the belt conveyor 22 toward the roadbed. Conveying to belt conveyor 26, the transshipment belt conveyor discharges ballast to the track of track 53 in the direction indicated by arrow 58.
