Apparatus for roughing edges of concrete casted blocks

摘要

An apparatus for roughing edges of solid concrete casted blocks that includes a block support conveyor for supporting and conveying a series of blocks and at least one roughing device disposed at a given distance from a block to be roughened; the device includes at least one impacting arm having a first end connected to a drive shaft having an axis and a second end connected to an impacting element; the shaft is connected to a drive element allowing the shaft to define an arcuate reciprocating motion causing the impacting element to impact the block and to crumble concrete from an edge of the block. The arm impacts the edge at an angle of about 45° relative to the axis of the drive shaft.
