ABSTRACT:
The multi-blade concrete cutting saw cuts blocks of concrete or aerated concrete into equal sized slates with one pass through the saw. The cutting saw is supported by a frame having a base, an upper support structure and a pair of guide rails. A conveyor track transports the concrete blocks through the cutting saw. A concrete block is forced along the conveyor track and passes through six equally spaced, diamond tipped cutting blades. Each of the resultant slates have equal dimensions and weight. The cutting blades are disposed along a drive shaft and are arranged across the width of the conveyor track. The cutting blades are driven in a counterclockwise direction by a drive belt that connects the drive shaft to a motor. The conveyor track may be automatically driven by a pair of belt drives.
