Summary of the invention
For above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of seismoreceiver for the pull-type creeper truck, it is arranged on the crawler belt, and can insert or built on stilts with the crawler belt rotation, thereby improves the efficient of geologic prospecting and engineering survey.
The utility model is the technical scheme that its purpose of realization is taked: a kind of seismoreceiver for the pull-type creeper truck, comprise the head that contacts to earth that shell is connected with front end with it, the described head that contacts to earth places the outside of rubber belt track, described shell places the inboard of rubber belt track, and the head that contacts to earth is connected with shell and is fixed on the rubber belt track; Described shell inner cavity establishes the wave detector core and by installing the thread ending cover sealing in its tail end, signal lead is established in the bottom of wave detector core.
The rear portion of described shell inner cavity is the inclined-plane boss shape, the cavity of boss shape front portion, inclined-plane and wave detector core clearance fit; The cavity internal diameter at boss shape rear portion, inclined-plane is established O shape circle between the two greater than wave detector core external diameter in the annular space that forms, press off a mouthful pressure ring on the described O shape circle, consists of the crimp of wave detector core, and described wave detector core is rigidly fixed in the shell inner cavity; Described signal lead is drawn from the opening part of opening pressure ring, and the bottom of described wave detector core scribbles silastic-layer, and signal lead seals in it.
Described opening pressure ring adopts metal or plastics, and its opening direction is towards the inboard of rubber belt track.
The described head that contacts to earth is hard place contact to earth head, hag contacts to earth and sandy ground a contacts to earth head.
Described wave detector core is transformed by microminiaturized, makes its volume less than or equal to 40 cubic centimetres.
The beneficial effects of the utility model:Can adapt to various geology surface and carry out the physics geologic prospecting, its profile and size and material therefor have the fabulous degree of coupling in its operating room and ground, the distorted signals of exporting behind the seismic event of accepting is little, signal to noise ratio (S/N ratio) is high, need not manually insert, prospecting prime cost is reduced, increase exponentially work efficiency and work quality.Rigidly fix owing to adopt between detector core body of the present utility model and the shell encapsulation, when seismic surveying, wave detector shell and the earth form the absolute mass body, make wave detector can be good at measuring earth's surface particle vibrations.The utility model is applicable to rigidity package requirements between all vibrations classes and other mechanics sensor core bodys and the shell.

Embodiment
Shown in Fig. 2-5, the utility model comprises the head that contacts to earth that shell 1 is connected with front end with it, the head that contacts to earth be divided into that hard place contacts to earth 7, hag contacts to earth 8 and sandy ground contact to earth 9, adapt to various geology surface and carry out the physics geologic prospecting, its profile and size and material therefor have the fabulous degree of coupling in its operating room and ground, and the distorted signals of exporting behind the seismic event of acceptance is little, signal to noise ratio (S/N ratio) is high.Contact to earth the head place rubber belt track 10 the outside.Shell 1 places the inboard of rubber belt track 10; Shell 1 inner chamber establishes wave detector core 4 and by installing thread ending cover 3 sealings in its tail end, signal lead 5 is established in the bottom of wave detector core 4.The rear portion of shell 1 inner chamber is the inclined-plane boss shape, the cavity of boss shape front portion, inclined-plane and wave detector core 4 clearance fit, and namely wave detector core 4 just can be put into wherein.The cavity internal diameter at boss shape rear portion, inclined-plane is greater than wave detector core 4 external diameters, establish in the annular space that forms between the two on O shape circle 6, the O shape circle 6 and press off mouthful pressure ring 2, consist of the crimp of wave detector core, by shell capping pressure, and the oblique angle on the shell closely wraps up compacting with detector core body.Make to form between the encapsulation of detector core body and shell and rigidly fix structure.Adopt crimp formula detector core body, have closely, with the features such as housing rigidity close-coupled, miniaturization, encapsulation are simple.
