MOBILE DEVICE FOR SEISMIC WAVE EXCITATION Russian patent published in 2008 - IPC G01V1/147 

FIELD: mining.

SUBSTANCE: device contains the shock mass fixed at the end of the lever which is suspended for its opposite end to enable rotation around the fixed axis, at the platform placed at the vehicle, with possibility of rotating around it, the activating instrument whose mobile load-bearing element is connected to the lever via flexible pulling unit, and the counterbalance installed at the platform on the side opposite to the shock mass. The device is also provided with the tower where the axis is fixed, and the tower is placed at the platform so as to modify the distance to the ground surface via elevating instrument installed at the vehicle. At that, the distance from the fixed axis to the support exceeds that from the fixed axis to the ground surface, and the shock mass is provided with the webbing under its support and made as the radiant unit and connected with the lever via friction joint.

EFFECT: device enhancement and simplification with simultaneous increase in seismic efficiency and productivity.
