ABSTRACT:
Ejector mechanism for the excavator bucket of a back hoe provides two laterally spaced ejector arms irrotatably carried on an ejector arm shaft journaled in horizontal orientation in the chamber of the excavator bucket to fit against the back and adjacent the sides of the bucket and pivot away from the back. A laterally medial powering arm irrotatably carried by the ejector arm shaft communicates through the back and extends forwardly to move upon an angulated ramp carried by the bucket tilting arm mechanism to pivot the ejector arms away from the back of the bucket as the bucket is tilted to a horizontal dumping position. The powering arm shaft is spring biased to maintain the ejector arms adjacent the bucket back when the bucket chamber is empty. The mechanism is retrofitable on various back hoe buckets of present day commerce.
