Rock stratum qualitative analyzer relying on drilling of drilling machine and use method of rock stratum qualitative analyzer

The invention relates to a rock stratum qualitative analyzer relying on drilling of a drilling machine and a using method, the rock stratum qualitative analyzer comprises a rock stratum analyzer and a fixed buffer device, the fixed buffer device is of a rigid cubic shell structure, the rock stratum analyzer is arranged in the fixed buffer device, and a buffer pad is arranged between the interior of the fixed buffer device and the rock stratum analyzer; a reserved charging hole is formed in the bottom face of the fixed buffer device, and a reserved switch hole and a reserved display hole are formed in the side face of the fixed buffer device. A CCD (charge coupled device) sensor, a laser reflector, a touch-operated display screen, a switch and a charging port are arranged in the rock stratum analyzer. According to the method, the real-time length of the rock mass drilled by the drilling machine can be accurately obtained by utilizing the high-precision characteristic of laser ranging, and then the surrounding
