Abstract

A soil preparation roller system for a soil preparation machine includes a roller body rotatable around a roller rotational axis having a carrier structure for the rotatable mounting of the roller body and having a carrier jacket supported on the radial outside on the carrier structure, a group of working jackets to be positioned abutting a carrier jacket outer side and providing a working outer side of a soil preparation roller. Each working jacket includes a plurality of working jacket segments to be arranged successively in the circumferential direction completely enclosing the roller body annularly, and the group of working jackets includes at least two working jackets having essentially equal mass to one another.

First claim

The invention claimed is:

1. A soil preparation roller system for a soil preparation machine, comprising:
a roller body rotatable around a roller rotational axis having a carrier structure for rotatable mounting of the roller body and having a carrier jacket supported radially on the outside on the carrier structure, said carrier jacket having a carrier jacket outer side, said carrier jacket outer side not providing a working outer side for coming into contact with a substrate to be prepared,
a group of working jackets, each working jacket of said group of working jackets being provided for being positioned abutting said carrier jacket outer side for providing the working outer side of a soil preparation roller comprising said carrier jacket and one of said working jackets positioned such as to about and surround said carrier jacket outer side, wherein each working jacket comprises a plurality of working jacket segments to be arranged in succession in the circumferential direction completely enclosing the roller body annularly,
wherein the group of working jackets comprises at least two working jackets having essentially equal mass to one another.

2. The soil preparation roller as claimed in claim 1 , wherein a vibration mechanism for generating a vibrational oscillation applied to the roller body is provided on the roller body.

3. The soil preparation roller as claimed in claim 1 , wherein at least two working jackets are constructed having equal number of working jacket segments.

4. The soil preparation roller as claimed in claim 1 , wherein at least two working jackets are constructed having segment shells of essentially identical outer circumferential structure to one another.

5. The soil preparation roller as claimed in claim 1 , wherein a mass of the at least two working jackets having essentially equal mass to one another is in the range of +/−15% of a working jacket target mass, and/or that a mass of the at least two working jackets having essentially equal mass to one another is in the range of +/−15% of a mean working jacket mass of these at least two working jackets having essentially equal mass to one another.

6. A soil preparation machine, comprising at least one soil preparation roller system as claimed in claim 1 .

7. The soil preparation roller system as claimed in claim 1 , wherein in each working jacket, each working jacket segment has a segment shell and on each segment shell, a plurality of fastening elements protruding radially inward is arranged fixed on a segment shell inner side facing toward the carrier jacket outer side of the carrier jacket and/or supported on the carrier jacket outer side, and wherein a fastening element passage opening is provided in the carrier jacket in association with each fastening element and each fastening element passing through a fastening element passage opening protrudes on a carrier jacket inner side of the carrier jacket for fixing with respect to the roller body.

8. The soil preparation roller as claimed in claim 7 , wherein in each one of at least three connecting regions located at a distance to one another in the direction of the roller rotational axis, at least one fastening element is fixedly arranged on each one of the segment shells.

9. The soil preparation roller as claimed in claim 1 , wherein the group of working jackets comprises at least one working jacket having working jacket segments providing an essentially unstructured, closed working outer side of the working jacket, and in that the group of working jackets comprises at least one working jacket having working jacket segments providing a structured working outer side of the working jacket.

10. The soil preparation roller as claimed in claim 9 , wherein in at least one working jacket having the structured working outer side, roller tools protruding radially outward are arranged on the working jacket segments-f.
