MACHINE FOR EDGE-MILLING CONCRETE BLOCKS THAT HAVE NOT YET HARDENED

摘要

The invention relates to a machine for edge-milling (rumbling) concrete blocks (1) that have not yet hardened. Said machine comprises a horizontal conveyer (3) for transporting concrete blocks lying in one position on a support plate (2) and a hammer mechanism (4) located above the horizontal conveyer (3). The hammers (8) of said hammer mechanism (4) are positioned one behind the other in several rows in the direction of transport and are offset, so that they can hammer the surface of the concrete blocks (1*) lying below. The individual hammers (8) are suspended on lifting drives (13 to 19) that allow said hammers to swing.
