Abstract

A sheath for a soil working roller includes a plurality of sheath segments mounted or mountable to surround a roller body of the soil working roller and following one another in the circumferential direction. A plurality of roller tools is arranged on an outer side of the sheath segments and at least one part of the roller tools includes an interchangeable holder mounted on a respective sheath segment and a replaceable tool detachably mounted or mountable on the interchangeable holder. A fastening opening is formed in the interchangeable holder for accommodating a fastening shaft of a replaceable tool mounted or to be mounted on the interchangeable holder. An impacted tool through opening is provided in association with the at least one interchangeable holder in the sheath segment supporting the same for engaging the fastening shaft of the replaceable tool mounted on the interchangeable holder with an impacted tool.

First claim

The invention claimed is:

1. Sheath for a soil working roller of a soil processing machine, wherein said sheath is rotatable about a roller axis of rotation and comprises a plurality of sheath segments, mounted or mountable to surround a roller body of the soil working roller and following one another in the circumferential direction, wherein a plurality of roller tools is arranged on an outer side of the sheath segments positioned to be facing away from the roller body, wherein at least one part of the roller tools comprise an interchangeable holder mounted on a respective sheath segment and a replaceable tool detachably mounted or mountable on the interchangeable holder of the same, wherein a fastening opening is formed in the interchangeable holder for accommodating a fastening shaft of a replaceable tool mounted or to be mounted on the interchangeable holder, wherein an impacted tool through opening is provided in association with the at least one interchangeable holder in the sheath segment supporting the same for engaging the fastening shaft of the replaceable tool mounted on the interchangeable holder with an impacted tool.

2. Sheath according to claim 1 , wherein the impacted tool through opening, provided in association with the at least one interchangeable holder, is arranged substantially coaxial with the fastening opening formed in the same.

3. Sheath according to claim 1 , wherein an interchangeable holder interior space is formed in the at least one interchangeable holder, wherein the fastening opening provided in this interchangeable holder is open to the interchangeable holder interior space and that the impacted tool through opening provided in association with this interchangeable holder is open to the interchangeable holder interior space.

4. Sheath according to claim 3 , wherein, in the case of a replaceable tool mounted on the at least one interchangeable holder, the fastening shaft of this replaceable tool extends into the interchangeable holder interior space and is positioned with a tool engaging end opposite the impacted tool through opening or engaging into the impacted tool through opening.

5. Sheath according to claim 3 , wherein, in the case of a replaceable tool mounted on the at least one interchangeable holder, the interchangeable holder interior space is substantially open only via the impacted tool through opening open to the same.

6. Sheath according to claim 1 , wherein, in the case of a replaceable tool mounted on the at least one interchangeable holder, the impacted tool through opening is substantially closed by the fastening shaft of this replaceable tool.

7. Method for changing a replaceable tool, mounted on the at least one interchangeable holder on a sheath, wherein said sheath is rotatable about a roller axis of rotation and comprises a plurality of sheath segments, mounted or mountable to surround a roller body of a soil working roller and following one another in the circumferential direction, wherein a plurality of roller tools is arranged on an outer side of the sheath segments positioned to be facing away from the roller body, wherein at least one part of the roller tools comprise an interchangeable holder mounted on a respective sheath segment and a replaceable tool detachably mounted or mountable on the interchangeable holder of the same, wherein a fastening opening is formed in the interchangeable holder for accommodating a fastening shaft of a replaceable tool mounted or to be mounted on the interchangeable holder, wherein an impacted tool through opening is provided in association with the at least one interchangeable holder in the sheath segment supporting the same, in which method, in the case of a sheath segment at least partially detached from the roller body, the fastening shaft, accommodated in the fastening opening of the at least one interchangeable holder, is impacted through the impacted tool through opening by means of an impacted tool to move the fastening shaft out of the fastening opening of the at least one interchangeable holder.

8. Method according to claim 7 , wherein the fastening shaft is moved out of the fastening opening by hitting and/or pressing impact.

9. Method according to claim 7 , wherein the fastening shaft is impacted by hitting impact of the impacted tool by means of an impacting tool.

10. Soil working roller for a soil processing machine comprising a roller body and a sheath surrounding the roller body, wherein said sheath is rotatable about a roller axis of rotation and comprises a plurality of sheath segments, mounted or mountable to surround a roller body of a soil working roller and following one another in the circumferential direction, wherein a plurality of roller tools is arranged on an outer side of the sheath segments positioned to be facing away from the roller body, wherein at least one part of the roller tools comprise an interchangeable holder mounted on a respective sheath segment and a replaceable tool detachably mounted or mountable on the interchangeable holder of the same, wherein a fastening opening is formed in the interchangeable holder for accommodating a fastening shaft of a replaceable tool mounted or to be mounted on the interchangeable holder, wherein an impacted tool through opening is provided in association with the at least one interchangeable holder in the sheath segment supporting the same.

11. Soil processing machine comprising at least one soil working roller according to claim 10 .

12. Sheath for a soil working roller of a soil processing machine, wherein said sheath is rotatable about a roller axis of rotation and comprises a plurality of sheath segments, mounted or mountable to surround a roller body of the soil working roller and following one another in the circumferential direction, wherein a plurality of roller tools is arranged on an outer side of the sheath segments positioned to be facing away from the roller body, wherein at least one part of the roller tools comprise an interchangeable holder mounted on a respective sheath segment and a replaceable tool detachably mounted or mountable on the interchangeable holder of the same, wherein a fastening opening is formed in the interchangeable holder for accommodating a fastening shaft of a replaceable tool mounted or to be mounted on the interchangeable holder, wherein an impacted tool through opening is provided in association with the at least one interchangeable holder in the sheath segment supporting the same for engaging the fastening shaft of the replaceable tool mounted on the interchangeable holder with an impacted tool, wherein, in the case of a replaceable tool mounted on the at least one interchangeable holder, the impacted tool through opening is substantially closed by the fastening shaft of this replaceable tool.
