Abstract
A mobile machine for withdrawing ballast from a ballast bed includes two receptacles, each of which including a separate intake port and discharge outlet, with a suction tube being selectively connectable to the intake ports of the receptacles. In order to selectively seal the intake ports in an air-tight manner, each intake port accommodates a closing element so as to allow an alternate emptying and filling of the receptacles without interruption of the withdrawal of ballast.
Claims17
A mobile machine for withdrawing ballast from a ballast bed of a track;
- comprising:
- a machine frame extending in longitudinal direction along a track and supported on undercarriages for mobility on the track;
- and
- a suction arrangement mounted on said machine frame and comprising
- a suction tube having one end terminating in an inlet opening for immersion in ballast of the ballast bed,
- a negative pressure generator for producing a suction at said inlet opening of said suction tube,
- a pair of receptacles, each of which includes a discharge outlet and at least one intake port, with said intake ports of said receptacles being selectively connectable to said suction tube, and
- closing means operatively connected to at least one intake port of each of said receptacles for allowing a selective air-tight sealing of said intake ports of said receptacles.
A mobile ballast bed machine, comprising:
- a machine frame supported on undercarriages for mobility on a track
- a suction means mounted on said machine frame for withdrawing ballast from a ballast bed;
- a pair of receptacles arranged on said machine frame, each receptacle having an intake port;
- a suction flow routing means for selectively connecting said intake ports of said receptacles with said suction means;
- and
- a flow regulating means operatively connected to said intake ports of said receptacles for allowing a selective air-tight sealing of said intake ports.
