VIBRATION ACTION SEISMIC EXPLORATION SYSTEM Russian patent published in 2012 - IPC G01V1/155 

FIELD: physics.

SUBSTANCE: seismic exploration system has a vehicle with an enclosed space, a cylindrical tray with an impact plate which can move downwards through a manhole at the bottom of the vehicle, a heavy piston, guides for vertical movement of the piston and the tray, cam-type vibrator placed between the tray and the piston and an electric motor with controlled rotational speed for the vibrator. The rotational speed of the shaft is controlled, which enables to obtain seismic signals of different frequencies.

EFFECT: high frequency of the seismic signal.
