MOBILE BALLAST CLEANING MACHINE

摘要

A mobile ballast cleaning machine comprises a frame running on two undercarriages a rear one of which is supported on a track section resting on cleaned ballast. A ballast excavating and conveying chain is mounted on the frame in front of this track section and a ballast screening mechanism on the frame receives the excavated ballast from the chain, cleans it and discharges the cleaned ballast to a storage receptacle arranged on the frame between the undercarriages. The storage receptacle has sufficient capacity to hold a volume of the cleaned ballast corresponding to that of the excavated ballast and a rising ballast conveyor is mounted in the storage receptacle for distributing the cleaned ballast therein. The cleaned ballast is discharged from the storage receptacle for redistribution by a ballast conveyor system and devices for regulating the flow of the cleaned ballast and for guiding the same between the discharge from the receptacle and the ballast conveyor system.
