Embodiment Construction
[0020] Such as Figure 2-5 As shown, the present invention includes a shell 1 and a grounding head connected to the front end. The grounding head is divided into a hard grounding head 7, a soft grounding head 8 and a sandy grounding head 9, which are suitable for physical geological exploration on various geological surfaces. The shape and size and the materials used have excellent coupling between the studio and the ground, and the output signal after receiving the seismic wave has little distortion and high signal-to-noise ratio. The ground contact head is placed on the outside of the rubber track 10 . The shell 1 is placed inside the rubber track 10; the inner cavity of the shell 1 is provided with a geophone core 4 and is closed by a threaded end cap 3 installed at its tail end, and the bottom end of the geophone core 4 is provided with a signal lead wire 5. The rear portion of the inner cavity of the housing 1 is in the shape of a beveled boss, and the cavity at the fron...
