Problems solved by technology

Any non-rigid connection between the geophone and the shell will destroy the absolute mass system formed between the geophone core-shell-earth
And this type of geophone is only suitable for sandy or soft ground, and cannot be used for hard ground

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...

Abstract

The invention relates to a seismic detector for a pull-type crawler, which comprises a shell and a grounding end connected with the front end of the shell and arranged outside a rubber belt track; the shell is arranged at the inside of the rubber belt track, and the grounding end and the shell are connected to be fixed on the rubber belt track; a detector core is rigidly fixed in the inner cavity of the shell and is closed by a thread end cover arranged at the tail end of the detector core; the bottom end of the detector core is provided with a signal lead; during seismic measuring, as the detector core body and the shell package are rigidly fixed and the shell of the detector and the ground form an absolute mass body, the detector can better measure the particle vibration of the earth surface. The seismic detector is suitable for the rigid packaging requirements between the shell and all vibration-type and other mechanical sensor core bodies. A contact, which is coupled with the ground, of the detector with the minitype structure is connected onto the mobile rubber belt track by threads, so the seismic detector is stable in work, reliable, efficient, suitable for various geological surfaces to carry out geophysical prospecting, low in manufacturing cost, simple and conveniently connected with a lower computer.

Description

[0001] technical field [0002] The invention relates to a geophone, in particular to a geophone used for a towed crawler vehicle. Background technique [0003] A geophone is a special sensor used in geological exploration and engineering surveying. It is a sensor that converts ground vibration into an electrical signal, or an energy conversion device that converts mechanical energy into electrical energy. like figure 1 shown. During geological exploration and engineering surveying, the geophones are manually buried on the ground one by one, the ground vibration caused by the seismic wave is converted into an electrical signal, and the electrical signal is sent to the seismograph through the cable; the digital seismograph will receive the electrical signal Amplify, convert to binary data through an analog / digital converter, organize data, and store data. After the measurement is completed, the geophones must be manually pulled out one by one. Therefore, when using this ge...
