Apparatus for removing the upper waste layer resulting in cutting plastic porous concrete blocks or the like
First Claim
1. An apparatus for removing a waste layer arising in cutting porous concrete blocks comprising:
- a beam which extends in a longitudinal direction above the porous concrete block and can be raised and lowered;
at least first and second horizontal support frames supported by said beam on an underside thereof which are movable in height by a motor, said first and said second support frames being arranged in at least one frame pair opposite one another on the two opposite sides of a vertical central plane of said beam which extends longitudinally along said beam;
support rails extending perpendicular to said vertical central plane and mutually spaced a predetermined distance apart from one another in said longitudinal direction to define gaps therebetween, at least a first plurality of said support rails being arranged on an underside of said first support frame and at least a second plurality of said support rails being arranged on an underside of said second support frame, said first plurality of said support rails being received in said gaps between said second plurality of said support rails, and vice versa; and
a plurality of spikes which can be inserted into the waste layer and protect from said support rails on said underside of each said support frame, said spikes each terminating at a point and being aligned with said points facing down at an angle, wherein all of said spikes of said first support frame of each said frame pair are parallel to one another and inclined at a first acute angle relative to said vertical central plane and all of said spikes of said second support frame opposite said first support frame are parallel to one another and inclined at a second acute angle relative to said vertical central plane which is opposite said first acute angle, each said support frame being movable relative to said beam in the direction of said spikes projecting

Abstract
The apparatus for removing the waste layer arising in cutting porous concrete blocks comprises a beam (1) which extends above the porous concrete block in its longitudinal direction and can be raised and lowered, and at least two horizontal support frames (2, 2'"'"') mounted thereon and movable in height, which are arranged in pairs opposite one another to the two sides of a vertical central plane (M) of the beam (1) and beneath the same. A plurality of spikes (5, 5'"'"') which can be stuck into the waste layer are provided on the underside of each support frame (2, 2'"'"') and are aligned with their points facing down at an angle. All spikes (5) of the first support frame (2) of each frame pair (P) are parallel to one another and inclined at an acute angle (μ) to the longitudinal central plane (M) and all spikes (5'"'"') of the opposite second support frame (2'"'"') are parallel to one another and inclined at an opposite acute angle (μl) to the longitudinal central plane (M). Each support frame (2, 2'"'"') is movable relative to the beam in the direction (B or C) of its spikes (5, 5'"'"').
