the machine, transported and loaded there into wagons or placed on the side of the rail track. It results This has the disadvantage that if there is a large accumulation of overburden in front of the machine, possibly also to the side in front of the machine, many wagons need to be lined up, but not the space available always enough. In particular, however, if too many vaggons are lined up on one side, the result is Machine trouble with banging

"of these wagons and with regard to the transport of the Debris from the machine on the wagons. That was also Capacity of one conveyor belt is not, always sufficient, to demand away the accumulating overburden according to the other working speed of the machine. The same disadvantages also occur if, as has also already been suggested, a backward movement conveying stripping belt provided v / ar. In such a case, the accumulation of overburden or

^ the V / aggons only from the front, ns.cn behind.

The invention has set itself the goal of avoiding the disadvantages of the known machines i: u and achieves this essentially by the fact that to move the overburden or the uncleaned ballast at least one, based on the working direction of the machine, after at the front and at least one backward conveying conveyor bond or d £ l. is provided.

A machine designed according to the invention can much easier than the known machines to adapt to the respective requirements · Is in the area There is more space in front of the machine for the removal of the overburden, if this is conveyed to the front, this results There was an insane situation in the area behind the machine, the delivery takes place to the rear. In the event of a large amount of overburden; or if due to the excessively high degree of pollution of the Ballast can no longer be cleaned but replaced with fresh ballast, the ■ tion of the overburden or the uncleaned bed gravel be done in both directions.

I) Ie arrangement of two in different directions pointing conveyor belts also has other advantages. Namely, is for another feature the invention at least one of these conveyor belts can be driven in different directions, this can Conveyor belt used to feed fresh gravel. A conveyor belt then conveys the overburden or the uncleaned ballast away from the machine, the other conveyor belt conveys fresh ballast towards the machine.

In this context it should be noted that in this specification the Besriff "conveyor belt od. Like. ^N in the broadest 3inne needed is. There are therefore considered to fall under this concept not only

The front, the Verfüllstelle to preferred space 25 has an adjustable base 27 and the rear space 26 a folding downwards ^J bottom piece 28 'of the container bottom in its entirety is formed obliquely sloping to the front, so that the dirt in the container, the bottom part provided 28 is closed, automatically slides forward.

Corresponds to the need for pure gravel at the filling points A and B the cleaned gravel delivered by the sieve 1o, the bottom 27 is drawn in with dashed lines in Pig, 3 moved rear position and the flap 24 closed. The pure ballast conveyed by the conveyor belts 23 is then filled directly at A. The supply of the coming from the sieve 1o Sehotters on the belts 23 is regulated by a flap 29, which at the same time also takes care of feeding the ballast to the chute. The division of the gravel coming from the sieve on the one hand to the belts 23 on the other hand to the chute 21 therefore depends on the respective remote-controllable position the flap 29.

If more gravel is delivered through the sieve than to Backfilling at points A and B is required, can be done by flaps 3o> which can be pivoted via the belts 23, a part of the ballast or the entire ballast into the space 26 of the memory 22 are promoted.

On the other hand, if there is not enough ballast brought by the belts 23, it can also be filled from the store will. At point A, this is done by opening the flap 24 accordingly (position shown in dashed lines); Pure gravel can be filled between the sleepers by lowering the bottom part 28.

In addition, it is also possible to move the floor 27 forwards so that the belts -23 promote into the space 25, with the discharge of the ballast at point A takes place through the corresponding control of the position of the floor 27.

In those cases in which the sieve 1o delivers too little or no cleaned gravel, e.g. because the whole excavated ballast is discharged via the conveyor belt 12 due to excessive contamination, can also use the belt 11 pure gravel can be fed. To the rate of this pure To ensure ballast to the conveyor belts 23 is a wedge-like lowerable on the belt 11 in the example shown Lehkorgan 31 is provided, which is also equipped with a remote-controlled drive 31 *.
