Abstract

An apparatus and a method for increasing the movement speed of the rail vehicle while carrying out measures for controlling weeds on track systems. A rail vehicle equipped with an apparatus for increasing the movement speed of the rail vehicle while carrying out measures for controlling weeds on track systems.

Claims (43)

1. An apparatus for weed control for a rail vehicle, comprising:

an identification system for identifying one or more locations along a stretch of track, upon which the rail vehicle moves, for weed control,

a weed control system for applying weed control at the identified one or more locations, and

a rail fixable to the rail vehicle, the rail configured to receive one or both of the identification system and the weed control system,

wherein,

one or both of the identification system and the weed control system are configured to move upon the rail in a direction that is opposite to a movement direction of the rail vehicle upon the stretch of track, and

the rail permits at least a portion of one or both of the identification system and the weed control system to carry out a movement upon the rail lateral to the movement direction of the rail vehicle.

2. The apparatus of claim 1 , wherein the weed control system comprises nozzles.

3. The apparatus of claim 1 , wherein the weed control system comprises spray nozzles for applying one or more herbicides.

4. The apparatus of claim 1 , wherein the weed control system comprises electrodes for applying an electric current upon contact with a plant so that the electric current flows at least partially through the plant.

5. The apparatus of claim 1 , wherein the weed control system comprises at least one emitter for emitting radiation in a direction of plants located on the track system.

6. The apparatus of claim 1 , wherein the identification system comprises one or more cameras that are connected to a computer system for analysing images.

7. A rail vehicle comprising one or more apparatuses of claim 1 .

8. The rail vehicle of claim 7 , wherein the one or more apparatuses are mounted on an underside of the rail vehicle.

9. The apparatus of claim 1 , wherein the rail is a closed loop.

10. The apparatus of claim 1 , wherein the rail permits:

movement of one or both of the identification system and the weed control system upon the rail in the same direction as the movement direction of the rail vehicle upon the stretch of track,

movement of one or both of the identification system and the weed control system upon the rail in the opposite direction as the movement direction of the rail vehicle upon the stretch of track, and

movement of one or both of the identification system and the weed control system upon the rail lateral to the movement direction of the rail vehicle upon the stretch of track.

11. The apparatus of claim 1 , wherein at least a portion of one or both of the identification system and the weed control system is configured to pivot.

12. The apparatus of claim 1 , wherein at least a portion of one or both of the identification system and the weed control system is configured to rotate.

13. A method comprising:

moving a rail vehicle upon a stretch of track in a movement direction, the rail vehicle having a rail fixed thereto,

identifying, via an identification system, at least one location for weed control, and

applying, via a weed control system, the weed control at the at least one location,

wherein,

the rail is configured to receive one or both of the identification system and the weed control system,

during the movement of the rail vehicle, one or both of the identification system and the weed control system move upon the rail in a direction that is opposite to the movement direction of the rail vehicle upon the stretch of track, and

at least a portion of one or both of the identification system and the weed control system carries out a movement upon the rail lateral to the movement direction of the rail vehicle upon the stretch of track.

14. The method of claim 13 , wherein the rail vehicle moves at a speed of at least 30 km/h while the weed control system applies the weed control.

15. The method of claim 13 , wherein the rail forms a closed loop.

16. The method of claim 13 , wherein at least a portion of one or both of the identification system and the weed control system carries out a pivoting movement opposite to the movement direction of the rail vehicle upon the stretch of track.

17. The method of claim 13 , wherein one or both of the identification system and the weed control system comprise a plurality of portions that carry out a rotation movement and a portion of the plurality of portions that is located closest to the track bed carries out a movement opposite to the movement direction of the rail vehicle upon the stretch of track.

18. The method of claim 13 , wherein the rail permits:

movement of one or both of the identification system and the weed control system upon the rail in the same direction as the movement direction of the rail vehicle upon the stretch of track,

movement of one or both of the identification system and the weed control system upon the rail in the opposite direction as the movement direction of the rail vehicle upon the stretch of track, and

movement of one or both of the identification system and the weed control system upon the rail lateral to the movement direction of the rail vehicle upon the stretch of track.

19. An apparatus for weed control for a rail vehicle, comprising:

an identification system for identifying one or more locations along a stretch of track, upon which the rail vehicle moves, for weed control;

a weed control system for applying weed control at the identified one or more locations;

a rail fixable to the rail vehicle, the rail configured to receive one or both of the identification system and the weed control system; and

a motor configured to move the identification system, the weed control system, or both upon the rail independent of the movement of the rail vehicle upon the stretch of track;

wherein one or both of the identification system and the weed control system are configured to move upon the rail in a direction that is opposite to a movement direction of the rail vehicle upon the stretch of track.
