Novel stone dividing machine

The utility model relates to a stone dividing machine which realize the machining to natural stone or artificial stone by a mixed mechanism combined of a crank-link mechanism and an arc track mechanism. The machine comprises a driving device, a crank-link mechanism, an arc track mechanism, a moving mechanism, a saw blade connecting device and a cooling device; and is characterized in that: the driving device is connected with the crank; the crank is connected with the linkage; the linkage is connected with the saw blade connecting device; the moving mechanism is mounted on the saw blade connecting device; and the moving mechanism is connected with the arc track mechanism. The machine of the utility model can meet the requirements for machining both high hardness stones and low hardness stones; can prolong the service life of a cutter head, can reduce energy consumption and machining cost; and can minimize the cutting slit and increase the product out-put percentage when machining high hardness stones.
