Abstract

A vibratory plate includes a ground plate, a vibration generator adjacent the front of the ground plate and a motor driving the vibration generator. The ground plate includes a sole plate, an upwardly inclined portion at the rear of the sole plate, two successive upwardly inclined portions at the front of the sole plate and an upwardly and rearwardly inclined portion from the front of the ground plate to the casing of the vibration generator. Extending downwardly from the casing of the vibration generator to the ground plate are supporting ribs positioned in the planes of the bearings of the vibration generator. A transverse rib extends upwardly from the ground plate at the rear of the supporting ribs. The ground plate, the ribs and the casing are an integral unit. In one embodiment that unit is cast aluminum with a steel facing on the bottom of the sole plate. In a second embodiment they are fiberglass reinforced plastic with a steel facing on the bottom of the sole plate.

Dependent claims

In a self-propelled vibratory plate excited by unbalance vibrations and comprising a ground plate having a front and a rear, a sole plate and an upwardly extending part at the front of the sole plate;

an unbalance vibrator including a casing, an eccentric centrifugal weight for generating an exciting force, and means including bearings rotatably mounting the weight in said casing for rotation about a horizontal axis transverse to the front to rear direction, said casing being adjacent the front of the ground plate, remote from the rear of the ground plate and above the ground plate;
a motor operatively connected to said weight to rotate the weight, said motor being positioned between the casing and the rear of the ground plate;
and resilient elements supporting the motor on the ground plate, the improvement comprising:
said casing being integral with said upwardly extending part of the ground plate along substantially the total width thereof, ribs positioned in the planes of said bearings, said ribs being integral with said ground plate and said casing.
