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.
Claims43
A crushing 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 crushing units is provided extending substantially in the direction of the roller axis of rotation and a plurality of second crushing units is provided extending substantially in the circumferential direction,
- wherein at least one second crushing unit includes at least one crushing projection projecting radially outward on the support structure between at least two first crushing units consecutively following one another in the circumferential direction,
- wherein for at least one second crushing unit, the at least one crushing projection has a circumferential spacing to the first crushing units accommodating said second crushing unit between themselves in the circumferential direction.
An earth working machine, comprising at least one earth working roller mounted on a machine frame to be rotatable about the roller axis of rotation, the 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 the direction of the roller axis of rotation and a plurality of second earth working units is provided extending substantially in the circumferential direction,
- wherein the earth working machine as designed as a trailer machine and does not have a traction drive, and
- wherein the earth working machine is to be hydraulically and/or mechanically coupled to a drive engine to provide the drive energy for a vibration generating mechanism provided in the at least one earth working roller.
An earth working machine, comprising at least one earth working roller mounted on a machine frame to be rotatable about the roller axis of rotation, the 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 the direction of the roller axis of rotation and a plurality of second earth working units is provided extending substantially in the circumferential direction,
- wherein the earth working machine is self-propelled and has a traction drive, and
- wherein a drive unit of the traction drive is provided to provide the drive energy for a vibration generating mechanism provided in the at least one earth working roller, or wherein a drive unit is provided on the earth working machine for the traction drive and a drive unit, designed separately from the drive unit for traction drive, is provided for the vibration generating mechanism of the at least one earth working roller.
