Known large vibrating conveyors are not readily suitable as such for conveying bulk materials or small articles into or out of a liquid bath, because the liquid transmits the vibrations to other structural parts, for example a vessel for the liquid, as a result of the incompressibility of the liquid. In order to remedy this, the vibrating conveyor device according to the invention has a compressible space or chamber underneath the vibrating part which damps the vibrations, when suitably coordinated with the liquid bath. The space is preferably gas-filled and its damping properties can be varied by feeding additional gas through a line which can be shut off by a member, or by bleeding some of the filling through a further line which can likewise be shut off by a member.
