Excavation system employing a jet pump

摘要

An excavation system comprises a bucket, defining an outlet at its base, in fluid communication with a suction tube in fluid communication with a jet pump, configured to create a suction in the suction tube. A related method of excavating comprises loading excavation material into a bucket which defines an outlet at its base, sizing the excavation material by sieving action of a guard substantially covering the bucket outlet, and suctioning the sized material though the bucket outlet using a vacuum created by a jet pump.
