[0002] We know that mechanical sawing can improve the yield rate of rough stone materials in stone mining, and circular saw is one of the commonly used equipment for cutting stone.

[0003] Existing circular saws are mostly used for sawing stone rough materials after mining. For example, the Chinese utility model patent with application number 2016204424271 discloses an "intelligent safety induction dust-proof stone saw machine for dam renovation", which includes a hydraulic device, a water tank, a control box and a stone sawing device. The hydraulic device uses the internal liquid as a working medium, and uses the pressure of the liquid to provide power for the up and down movement of the stone saw blade. The stone sawing device driving motor drives the stone sawing device sliding wheel to rotate, so that the stone sawing device slides left and right on the slide rail, and the auxiliary stone saw blade cuts the stone placed on the stone sawing machine workbench, and the stone sawing blade driving motor drives the stone sawing blade to rotate to cut the stone. Before cutting, the stone to be cut needs to be placed on the stone sawing machine workbench, which is obviously not suitable for mining stone rough materials in mines.
