Geological analysis quality control device and use method thereof

A geological analysis quality control device disclosed by the present invention comprises a base and a rack, a third transmission screw rod is rotatably mounted on the base, a first driving motor is fixedly mounted on one side of the base, the output end of the first driving motor is fixedly connected with one end of the third transmission screw rod, and guide rods are arranged on both sides of the third transmission screw rod. The base is provided with a moving seat, the bottom end of the moving seat is fixedly connected with a lead screw nut on the third transmission lead screw, and the lower surface of the moving seat is in sliding connection with a guide rod through a sliding sleeve. By arranging the crushing mechanism, forward rotation of a first transmission lead screw can be utilized to enable a lead screw nut to move downwards and drive a sleeve and a pressure plate to move downwards, rock in a treatment cylinder is crushed by utilizing a conical thorn part on the lower surface of the pressure plate,
