Abstract

Soil compactor including a compaction drum rotatably supported by a compaction roller frame, wherein the compaction drum frame comprises two longitudinal members arranged in a direction longitudinal to the compactor on both sides of the compaction roller and supporting said compaction roller, and, connecting the two longitudinal members together, two cross members arranged in a direction perpendicular to the compactor and along both sides of the compaction roller, wherein the compaction roller frame is connected to a compactor main frame via one of the two cross members, and wherein at least one sight opening is provided within the other of the two cross members.

First claim

The invention claimed is:

1. Soil compactor comprising a compaction roller rotatably supported by a compaction roller frame, wherein the compaction roller frame comprises two longitudinal members arranged in a direction longitudinal to the compactor on both sides of the compaction roller and supporting said compaction roller, and, connecting the two longitudinal members together, two cross members arranged in a direction perpendicular to the compactor and along both sides of the compaction roller, wherein the compaction roller frame is connected to a compactor main frame via one of the two cross members, and wherein at least one sight opening is provided within the other of the two cross members, wherein the at least one sight opening is essentially open upward in a direction vertical to the compactor, and wherein the upper area of the at least one sight opening is furnished with at least one brace bridging said sight opening in a direction perpendicular to the compactor, and further wherein the at least one brace has a smaller cross-sectional area than the other cross member in the area of the at least one sight opening.

2. Soil compactor according to claim 1 ,
wherein a sight opening is centrally arranged in the middle of the compactor in a direction perpendicular to the compactor, and/or that the least one sight opening spans a distance in a direction perpendicular to the compactor of at least 50% of the distance spanned by the other cross member in a direction perpendicular to the compactor, and/or that the at least one sight opening spans a distance in a direction vertical to the compactor of at least 50% of the distance spanned by the other cross member in a direction vertical to the compactor.

3. Soil compactor according to claim 1 ,
wherein the sight opening is divided into two sight opening areas by a plate-like support element braced by the brace, which, in a direction perpendicular to the compactor, is arranged essentially in the middle of the compactor as well as with respect to the other cross member.

4. Soil compactor according to claim 1 ,
wherein the other cross member comprises at least two cross member support elements arranged one above the other in a direction vertical to the compactor and forming a sight opening between them.

5. Soil compactor according to claim 1 ,
wherein the other cross member is offset upward with respect to the other cross member in a direction vertical to the compactor.

6. Soil compactor according to claim 1 ,
wherein a leveling blade is supported by the compaction roller frame so as to be movable in a direction vertical to the compactor.

7. Soil compactor according to claim 6 ,
wherein the upper area of the leveling blade in a direction vertical to the compactor has at least one leveling blade sight opening.

8. Soil compactor according to claim 7 ,
wherein the upper area of the leveling blade is formed by a plurality of leveling blade bars essentially parallel to one another, wherein at least one leveling blade sight opening is formed between at least two leveling blade bars.

9. Soil compactor according to claim 6 ,
wherein a leveling blade lifting mechanism is supported in relation to the leveling blade and the other cross member.

10. Soil compactor according to claim 3 , wherein a leveling blade is supported by the compaction roller frame so as to be movable in a direction vertical to the compactor, and wherein a leveling blade lifting mechanism is supported in relation to the leveling blade and the other cross member, and further wherein the leveling blade lifting mechanism is supported by the support element.

11. Soil compactor according to claim 3 ,
wherein a sight opening is centrally arranged in the middle of the compactor in a direction perpendicular to the compactor, and/or that the least one sight opening spans a distance in a direction perpendicular to the compactor of at least 50% and/or that the at least one sight opening spans a distance in a direction vertical to the compactor of at least 50%.

12. Soil compactor according to claim 10 , wherein a leveling blade lifting mechanism is supported in relation to the leveling blade and the other cross member.

13. Soil compactor comprising a compaction roller rotatably supported by a compaction roller frame, wherein the compaction roller frame comprises two longitudinal members arranged in a direction longitudinal to the compactor on both sides of the compaction roller and supporting said compaction roller, and, connecting the two longitudinal members together, two cross members arranged in a direction perpendicular to the compactor and along both sides of the compaction roller, wherein the compaction roller frame is connected to a compactor main frame via one of the two cross members, and wherein at least one sight opening is provided within the other of the two cross members, wherein the other cross member comprises at least two cross member support elements arranged one above the other in a direction vertical to the compactor and forming a sight opening between them.

14. Soil compactor comprising a compaction roller rotatably supported by a compaction roller frame, wherein the compaction roller frame comprises two longitudinal members arranged in a direction longitudinal to the compactor on both sides of the compaction roller and supporting said compaction roller, and, connecting the two longitudinal members together, two cross members arranged in a direction perpendicular to the compactor and along both sides of the compaction roller, wherein the compaction roller frame is connected to a compactor main frame via one of the two cross members, and wherein at least one sight opening is provided within the other of the two cross members, wherein a leveling blade is supported by the compaction roller frame so as to be movable in a direction vertical to the compactor, and wherein the upper area of the leveling blade in a direction vertical to the compactor has at least one leveling blade sight opening.

15. Soil compactor according to claim 14 , wherein the upper area of the leveling blade is formed by a plurality of leveling blade bars essentially parallel to one another, wherein at least one leveling blade sight opening is formed between at least two leveling blade bars.

16. Soil compactor according to claim 15 , wherein the leveling blade bars extend essentially parallel to the compaction roller axis of rotation.

17. Soil compactor according to claim 14 , wherein a leveling blade lifting mechanism is supported in relation to the leveling blade and the other cross member.

18. Soil compactor according to claim 17 , wherein:
the at least one sight opening is essentially open upward in a direction vertical to the compactor,
the upper area of the at least one sight opening is furnished with at least one brace bridging said sight opening in a direction perpendicular to the compactor, wherein the at least one brace has a smaller cross-sectional area than the other cross member in the area of the at least one sight opening,
the sight opening is centrally arranged relative to a middle of the compactor in a direction perpendicular to the compactor,
the sight opening is divided into two sight opening areas by a support element braced by the brace, which, in the direction perpendicular to the compactor, is arranged essentially in the middle of the compactor as well as with respect to the other cross member, and
wherein the leveling blade lifting mechanism is supported by the support element.
