PLATE-AND-SPRING VIBRATORY DRUM Russian patent published in 2010 - IPC E01C19/28 E02D3/26 

FIELD: construction.

SUBSTANCE: device consists of racks on which there installed is shaft by means of bearing assemblies; on external side of outer diametre of shaft there fixed is drum made in the form of a pack of spring washers with internal side of its inner diametre; and inside shaft there installed is magnetostricting vibration source consisting of the striker provided with possibility of being moved in the plane longitudinal to axis of drum by means of electromagnetic coil the function of which is to create magnetic forces, and return spring the function of which is to create the back movement of striker in the plane longitudinal to axis of drum under impact of elastic forces; at that, magnetostricting vibration source is provided with possibility of creation of vibration field, and as a result, deforming impact on pack of spring washers by means of thrust plate which is welded to drum, and the function of which is to transmit the vibration impact from drum of magnetostricting vibration source directly to the drum itself.

EFFECT: obtaining the required sealing impact on ground of any type; optimising the design with purpose of its simplification and improvement of reliability.
