Abstract
An earth moving and tamping apparatus rig is provided which can backfill a trench and compact the backfill materials up to 95% compaction. A bucket and a vibrator are attached to a backhoe. The bucket retrieves the filling material and either dumps the material into a trench or sifts it through adjustable screening blades that form the bottom of the bucket. The apparatus includes a means to swivel the bucket 360.degree. with respect to the boom. The end of the bucket then compacts the filling materials into the trench. Each moving rig apparatus may also be equipped with an alternative two-bucket system, where one bucket fits inside the other one or is along side thereof. For trenches as wide as two feet to increase the area of dirt tamped, the two-bucket may be secured in juxtaposition to each other. For more narrow trenches, the second bucket may be closed inside the first bucket and the area tamped will only be the width of a single bucket. The earth moving and tamping apparatus rig is a device by which a backfilling job may be done more efficiently and less expensive than the present method employing multiple workers and machines.
