High-frequency point seismic source excitation device applied to seismic image

The utility model discloses a high-frequency point seismic source excitation device applied to seismic mapping, belongs to the field of seismic research, and solves the problems that sound wave noise generated by an existing knocking mode affects data, and knocking energy is not easy to control. The hammer comprises a rod-shaped main hammer body, the lower end of the main hammer body is conical, the lower section of the main hammer body is a hollow section, the interior of the hollow section is of a cavity structure, and a plurality of exhaust holes are formed in the side wall of the hollow section. According to the utility model, the hypothesis of reducing sound wave noise and improving the energy consistency of the seismic source in a seismic mapping method is realized, meanwhile, the smaller instantaneous grounding area is closer to a point seismic source, the seismic source has higher frequency characteristic due to instantaneous excitation, the excitation energy is easy to control, and the seismic source
