Abstract
The invention relates to a device for processing a hard surfacing, the device comprising a rotatable hammering unit configured to process the hard surfacing under the hammering unit with hammers, the hammering unit comprising a substantially flat first and second disc with a number of hammer wheels on the underside of the second disc, wherein the coupling between the first and second disc is formed by one or more vibration-damping coupling elements. The invention also relates to a method for processing a hard surfacing with a vehicle provided with the device described herein.
Claims22
Device for processing a hard surfacing, the device comprising:
- a frame to be mounted on a vehicle;
- a support coupled to the frame;
- a drive motor, mounted on the support, with drive shaft for rotating a hammering unit relative to the support;
- a rotatable hammering unit configured to process the hard surfacing under the hammering unit by hammering, grinding and/or polishing the hard surfacing with hammers, the hammering unit comprising:
- a substantially flat first disc;
- a substantially flat second disc coupled via at least three coupling elements to the first disc and extending parallel to the first disc;
- wherein the flat first disc is connected to the drive shaft of the drive motor for a purpose of rotating the first and second flat discs in a plane of the first disc,
- wherein the second disc comprises on a flat side remote from the first disc a plurality of hammers, wherein the hammers are distributed substantially uniformly along a circular periphery, a central point of which corresponds to a central point of the second disc;
- and
- wherein the at least three coupling elements are vibration-damping coupling elements configured to provide a vibration-damping coupling between the first and second disc,
- wherein essentially the only coupling between the first and second disc is formed by the at least three vibration-damping coupling elements, and
- wherein the at least three vibration-damping coupling elements are arranged between the first and second disc at positions which are substantially uniformly distributed over one or more concentric circles, the central points of which correspond to the central point of the second disc.
