The invention relates to ballast cleaning devices for railway track beds. In known devices the cleaned gravel is returned to the track bed on suitable conveyors but problems occur when heretofore known machines had to stop their forward progress along the track resulting in irregularities in the rate of delivery of the cleaned gravel. The invention provides a distribution hopper for the cleaned gravel, which hopper has at least two openings in its base portions which extend parallel to the direction of the movement of the machine, the hopper having a capacity capable of receiving all of the gravel being treated at one time by the machine. In this fashion when the machine stops its forward progress the hopper can receive and store the gravel being processed at that time and distributed evenly back to the track bed. |
