The invention discloses a stone mining cutting and grinding machine. The stone mining cutting and grinding machine comprises a bottom plate, a stand column and a position adjusting device, the stand column is perpendicularly arranged on the bottom plate, the position adjusting device is used for driving the stand column to slide in the width direction of the bottom plate, the position adjusting device is further used for driving the stand column to slide in the length direction of the bottom plate, a support is arranged on one side of the stand column, the support can slide on the stand columnin the vertical direction, a rotatable circular saw blade and a grinding device capable of moving up and down are further arranged at the end, far away from the stand column, of the support, the circular saw blade and the grinding device are sequentially arranged on the support on the same horizontal plane, the circular saw blade is used for machining a groove on a stone wall, and the grinding device is used for grinding and forming the stone on the cut machined groove. The provided stone mining cutting and grinding machine has the advantages that the stone subjected to preliminary grinding can be conveniently and directly mined from a stone forest and a mining area, and the stone machining procedures can be reduced.

Stone mining cutting and grinding machine

The utility model relates to a rotating mechanism of a power device of a wire sawing machine and belongs to the field of stone cutting machines. The wire sawing machine comprises a guide rail, a machine body arranged on the guide rail, a walking device and the power device, and the rotating mechanism is connected with the power device. The rotating mechanism comprises a slewing bearing device, the slewing bearing device comprises a shell and a slewing bearing arranged in the shell, the slewing bearing comprises an inner ring, an outer ring, a worm and a driving motor, the worm is connected with the outer ring in a meshed mode, and the driving motor is connected with the worm through a speed reducer. The rotating mechanism further comprises a first shaft sleeve fixed to the machine body and a second shaft sleeve fixed to the power device, the first shaft sleeve is fixedly connected with the inner ring, and the second shaft sleeve is fixedly connected with the outer ring. Thus, the slewing bearing device is ingeniously used in the rotating mechanism, the slewing bearing can bear large axial and radial loads, and the bearing performance of the whole rotating mechanism is improved; in addition, by means of the structure, the rotating mechanism is made to be more compact and reasonable in overall structure layout and more stable in transmission.
