Mobile ballast cleaning machine

摘要

A mobile cleaning ballast machine comprises an elongated machine frame; an endless ballast excavating and conveying chain adjustably mounted on the machine frame; and a ballast screening installation arranged to receive the excavated ballast conveyed by the endless chain. The excavated ballast is washed in an apparatus comprising an elongated conveyor receiving the excavated ballast conveyed by the endless chain and conveying the received ballast in a conveying path to the ballast screening installation, a water tank mounted on the machine frame below the elongated conveyor, the elongated conveyor extending above the water tank and the screening installation, a series of nozzles directed towards the conveying path and receiving water from the tank, and a drainage sieve for returning the water from the elongated conveyor to the water tank.
