Rock stratum crushing drilling tool for oil exploitation

The invention belongs to the technical field of drilling tools, in particular to a rock stratum crushing drilling tool for oil exploitation, and provides the following scheme that the rock stratum crushing drilling tool comprises a bottom plate, a connecting plate, a sliding block, a first transmission plate, a gear and a mounting column, the surface of the bottom plate is rotatably connected with a rotating plate, and the surface of the rotating plate is fixedly connected with a mounting plate; a hydraulic rod for driving the connecting plate to ascend and descend is arranged on the side face of the mounting plate. By arranging an embedded rod, the embedded rod is deviated from the circle center of a disc, when the disc rotates, the embedded rod can be driven to slide in a sliding groove in the surface of a second transmission plate, then a sliding rod at the bottom of the second transmission plate can slide left and right along a bottom plate, and when the sliding rod is embedded in a rotating plate, when t
