Abstract
An ejector mechanism operates to force silt material from individual chambers in a rotating wheel of a silt removal machine. The rotating wheel removes the silt material from under a shallow body of water by collecting it in individual chambers of the rotating wheel. Since the silt material is generally soft and sticky, the ejector mechanism urges the silt material from the respective chambers as the wheel rotates. The ejector mechanism includes a rotating crank that rotates as the excavator wheel rotates and is connected by a link to an ejector arm.
