Abstract
Automatic dredge for geological marine surveys which is made up of a structure extended vertically along which a dredging head is mounted, sliding, which has vertical guide mechanisms above for a striking hammer which is associated to the head by at least one dual acting jack fed by compressed air which is designed first to slowly raise the hammer and then to push it forcibly down to vibrate violent and subsequent blows on the head allowing the tube to penetrate in the sea bed to be dredged.
