Abstract

Device for processing a ground surface of artificial turf comprising filler, the device comprising a frame (11) and moving means arranged for moving the device over the ground surface in a working direction, a supplier arranged for taking up a flow of material from the ground surface, such as dirt and filler, and for supplying the flow to a processing device (3) arranged for processing the flow of material, wherein the supplier extends at a distance above the ground surface and that the device further comprises an engaging device (41) arranged for engaging the material on the ground surface for loosening said material.

Claims

1. A device for processing a ground surface of artificial turf comprising:

a frame and moving means for moving the device over the ground surface in a working direction,

a supplier configured for taking up a flow of material from the ground surface and for supplying the flow to a processing component arranged for processing the flow of material, and

an engaging component configured for engaging the material on the ground surface for loosening said material,

wherein the supplier extends at a distance above the ground surface.

2. The device of claim 1, wherein the engaging component is configured in front of the supplier viewed in the working direction .

3. The device of claim 1, wherein the engaging component is configured to engage the material on the ground surface with a speed substantially equal to or smaller than a working speed of the device moving in the working direction.

4. The device of claim 1, wherein the engaging component is configured to engage the material on the ground surface with a predetermined working depth, wherein the working depth is approximately 5 mm above the base layer of the artificial turf.

5. The device of claim 1, further comprising a sensor for sensing the ground surface, wherein the engaging component is configured to obtain a working depth relating to a sensed property of said ground surface.

6. The device of claim 1, wherein the engaging component is configured to engage the material on the ground surface along at least the width of a working width of the supplier.

7. The device of claim 1, wherein the engaging component comprises at least one engaging member configured for engaging the material on the ground surface, wherein the engaging member is manufactured from a resilient material.

8. The device of claim 1, wherein the engaging component comprises a plurality of engaging members.

9. The device of claim 8, wherein the engaging members comprise elongate engaging members, wherein a first end of the elongate members is configured for engaging the material and wherein a second end is held to the frame.

10. The device of claim 9, wherein the elongate member comprises a strip or tuft, wherein said strip or tuft is manufactured from metal, plastic or a combination thereof.

11. The device of claim 9, wherein at least the first end of the elongate member is biased towards the ground surface, wherein the length of the elongate member is adjustable.

12. The device of claim 1, wherein the engaging component comprises a rotating member, wherein the rotating member includes a plurality of engaging members.

13. The device of claim 12, wherein the engaging members are finger shaped, wherein a first end of the engaging members is arranged to engage the material on the ground surface and wherein a second end of the engaging members are connected to the rotating member.

14. The device of claim 12, wherein the engaging members is manufactured from a plastic or vulcanized rubber.

15. The device of claim 12, wherein the rotating member is arranged to rotate a direction such that the engaging members move in the same direction as the ground surface.

16. The device of claim 12, wherein the device further comprises a motor for driving the rotating member.

17. The device of claim 16, wherein the motor is configured to rotate the rotating member for moving the engaging members over the ground surface with a speed different from the working speed.

18. The device of claim 1, wherein the processing component comprises at least one nozzle for spraying a liquid on at least a part of the flow of material.

19. A method for processing a ground surface of artificial turf comprising filler, the method comprising:

moving a device over the ground surface in a working direction;

engaging a material on the ground surface with a component of the device;

taking up a flow of the material from the ground surface with a supplier, which extends at a distance above the ground;

supplying the flow from the supplier to a processor; and

processing said flow of material with the processor.

20. The method claim 19, wherein the engaging component engages the material on the ground surface with a speed substantially equal to or smaller than a working speed of the device moving in the working direction.

21. The method claim 19, wherein the engaging component engages the material on the ground surface with a predetermined working depth, wherein the working depth is approximately 5 mm above a base layer of the artificial turf.

22. The method claim 19, further comprising sensing the ground surface, wherein the engaging component obtains a working depth relating to a sensed property of said ground surface.
