ABSTRACT:
A vibratory plate compactor with aggregate feed system includes a frame, a soil compacting plate and a drive mechanism, such as a hydraulic motor, is mounted on the frame and has a rotatable drive shaft which uses a V-belt to drive a vibratory actuator on the tamping plate. The frame also carries a hopper that uses a screw conveyor to force the stored aggregate into a vertical conduit. A tamping piston forces aggregate out of the vertical conduit, through apertures in the compactor plate and compacts the loose soil with a multitude of blows, the vibratory plate is then actuated to further compact the aggregate. The process is repeated until the cavity is filled and compacted to the required density. The vibratory plate compactor with aggregate feed system is ideally suited to filling and compacting aggregate in used automobile tires that are used in the formation of a tire wall.
