Abstract

A vibration plate system with an unbalance generator rigidly mounted on a vibration plate, and with an internal combustion engine which pertains to a surload and is resiliently cushioned relative to the vibration plate, the internal combustion engine serving as energy generator. The internal combustion engine drives an electric generator arranged on the surload, and the unbalance generator is driven by a pole changeable and reversible electric motor connected to the vibration plate. The last mentioned electric motor operates with the electric energy generated by the generator.

Claims

1. A vibration plate system which includes:

a vibration plate, a surload, cushioning means interposed between said vibration plate and said surload and resting the latter on said vibration plate, said surload comprising an internal combustion engine and an electric generator means drivingly connected to said engine to be driven thereby, electric motor means adapted to be supplied with electric energy from said generator means and including rotor means with rotor shaft means, and means eccentrically supporting said rotor shaft means and together said electric motor means forming unbalance generator means operatively connected to said vibration plate for imparting an unbalance thereon.

2. A vibration plate system according to claim 1, in which said electric motor is a pole changeable and reversible electric motor.

3. A vibration plate system according to claim 1, in which said electric generator means are three-phase current devices.

4. A vibration plate system according to claim 1, in which said unbalance generating means includes an unbalance body adjustable for varying its distance from the axis of rotation of said electric motor means.

5. A vibration plate system according to claim 1, in which said unbalance generator means include two unbalance generators having their shafts in alignment with each other and extending on opposite sides of the central plane therebetween, and in which said electric motor means include two electric motors.

6. A vibration plate system according to claim 1, in which said electric generator means and said electric motor means are connected to each other by steel core cables.
