  • Method and apparatus for implanting geophones into the earth
    Patent number: 5315074
    Abstract: An apparatus (10) for implanting geophones (98) includes an implanting device (12) pivotally mounted on the end of a tractor (14) for movement from one predetermined location to another predetermined location for implanting a plurality of geophones (98). The implanting device (12) has a main support frame (16) supporting a vibratory frame (18) which receives a push tube (68) in sliding relation. The lower end of the push tube (68) accepts a geophone (98) for insertion therein. Downward movement of push tube (68) implants the geophone (98) as shown in FIG. 4. To assist in implanting the geophone (98), the vibratory frame (18) and the push tube (68) are vibrated for vibration of the lower end of the push tube (68) during implantation.
