Abstract

An earth working roller comprises a support structure ( 11 ), wherein to form a roller body ( 36 ) rotatable about a roller axis of rotation (A) on a radially outer region of the support structure ( 11 ), a plurality of first earth working units ( 30 ) is provided extending substantially in the direction of the roller axis of rotation (A) and/or a plurality of second earth working units ( 38 ) is provided extending substantially in the circumferential direction.

First claim

The invention claimed is:

1. An earth working roller comprising a support structure, wherein to form a roller body rotatable about a roller axis of rotation on a radially outer region of the support structure, a plurality of first earth working units is provided extending substantially in a direction of the roller axis of rotation,
wherein the support structure comprises a plurality of support disks arranged consecutively in the direction of the roller axis of rotation and connected to one another to form the roller body, wherein the plurality of first earth working units extending substantially in the direction of the roller axis of rotation is provided on an outer peripheral region of at least one part of the support disks,
wherein the support structure is arranged surrounding a peripheral wall of a housing for a vibration generating mechanism and is connected to the peripheral wall, and
wherein the vibration generating mechanism with at least one unbalanced mass rotatable about an unbalanced axis of rotation is arranged in the housing, and/or wherein the housing is closed by an end wall in at least one axial end region, and
wherein, in at least one axial end region of the roller body, at least one support disk is connected to the support disks arranged surrounding the peripheral wall by at least one part of the first earth working units.

2. The earth working roller according to claim 1 , wherein the roller body is designed as substantially open radially outward in its outer peripheral region.

3. The earth working roller according to claim 1 , wherein at least one part of the support disks is designed with a substantially circular outer peripheral contour, and/or wherein at least one part of the support disks comprises a plurality of support disk segments arranged spaced circumferentially apart from one another.

4. The earth working roller according to claim 1 , wherein the support structure comprises a plurality of support struts supporting in their radially outer region the plurality of first earth working units extending substantially in the direction of the roller axis of rotation and/or supporting in their radially outer region a plurality of second earth working units extending substantially in a circumferential direction provided on an outer peripheral region of at least one part of the support disks.

5. The earth working roller according to claim 1 , wherein at least one part of the support disks is arranged surrounding the peripheral wall of the housing, wherein the support disks arranged surrounding the peripheral wall are fixedly connected to the peripheral wall, and/or wherein the support disks arranged surrounding the peripheral wall are fixedly connected to the peripheral wall by welding.

6. The earth working roller according to claim 1 , wherein the unbalanced axis of rotation substantially corresponds to roller axis of rotation, and/or wherein an unbalanced drive motor assigned to the at least one unbalanced mass is arranged on an end wall.

7. The earth working roller according to claim 1 , wherein at least one first earth working unit comprises an earth working bar fixedly connected to the support structure.

8. The earth working roller according to claim 7 , wherein each first earth working unit comprises an earth working bar, and/or wherein a plurality of earth working bars is arranged spaced circumferentially apart from one another.

9. The earth working roller according to claim 1 , wherein at least one first earth working unit comprises an earth working bar fixedly connected to the support structure, and
wherein the at least one earth working bar is fixedly connected to all support disks and/or wherein the at least one earth working bar is fixedly connected to at least a part of the support disks by welding.

10. The earth working roller according to claim 1 , wherein at least one first earth working unit comprises a tool carrier fixedly connected to the support structure, and wherein an earth working tool is detachably connected or connectable to at least one tool carrier.

11. The earth working roller according to claim 10 , wherein each first earth working unit comprises a tool carrier, and/or wherein at least one tool carrier has a concave contour with respect to the outer periphery of the roller body, and/or wherein a plurality of tool carriers is arranged spaced circumferentially apart from one another.

12. The earth working roller according to claim 10 , wherein at least one earth working tool is designed as an earth working bar.

13. The earth working roller according to claim 12 , wherein the earth working bar comprises a socket region designed for securing on a tool carrier and an earth working region projecting radially outward from the socket region for an earth working tool mounted on a tool carrier.

14. The earth working roller according to claim 13 , wherein at least one earth working tool is connected or connectable in its socket region by screwing and/or clamping to a tool carrier.

15. The earth working roller according to claim 10 , wherein at least one earth working tool comprises an earth working shell positioned or positionable surrounding the support structure radially outwardly, and connected or connectable to at least two tool carriers.

16. The earth working roller according to claim 6 , wherein a plurality of earth working shells consecutively following one another in the circumferential direction is connected or connectable to a tool carrier in both peripheral end regions respectively, and/or wherein at least one earth working shell is connected or connectable to the at least two tool carriers by screwing.

17. The earth working roller according to claim 15 , wherein at least one roller tool is mounted on at least one earth working shell, and/or wherein at least one earth working shell is designed with a grid-like structure.

18. The earth working roller according to claim 17 , wherein at least one roller tool is mounted on each earth working shell, and/or wherein a plurality of roller tools is mounted on at least one earth working shell, and/or wherein at least one interchangeable holder is fixedly connected to at least one earth working shell and at least one roller tool is detachably connected or connectable to the at least one interchangeable holder.

19. The earth working roller according to claim 18 , wherein at least one roller tool comprises a chisel, and/or wherein at least one roller tool comprises a tamping foot.

20. The earth working roller according to claim 15 , wherein at least one earth working shell has in at least one peripheral end region a tool carrier engagement region adapted to a concave contour of a tool carrier.

21. The earth working roller according to claim 1 , wherein at least one first earth working unit comprises a tool carrier fixedly connected to the support structure, and wherein an earth working tool is detachably connected or connectable to at least one tool carrier, and
wherein the at least one tool carrier is fixedly connected to each support disk, and/or wherein the at least one tool carrier is fixedly connected to at least one part of the support disks by welding.

22. The earth working roller according to claim 1 , wherein at least one earth working shell is positioned or positionable surrounding all support disks radially outwardly in a peripheral region, and
wherein at least one earth working tool comprises an earth working shell positioned or positionable surrounding the support structure radially outwar
