Abstract
A vibratory compactor attachment for mechanical equipment, such as an excavator or backhoe. The attachment includes a support frame which is pivotally attached to both the boom and the tilt arms of the excavator. One end of the support frame carries a scraper blade that can be used for leveling soil prior to compaction. A drum frame is connected to the support frame and a compaction drum is mounted for rotation on the drum frame. To vibrate the drum, an exciter is mounted on the drum frame and resilient isolation mounts interconnect the support frame and the drum frame to minimize the transmission of vibration to the support frame.
Claims12
A vibratory compaction attachment for mechanical equipment, comprising a first frame having a pair of opposite sides, first mounting means for connecting a lift mechanism to said first frame, second mounting means for connecting a tilt mechanism to said first frame, second frame including a pair of side members each disposed adjacent a side of said first frame, said second frame also including a transverse connecting member connecting said side members and disposed beneath said first frame, a compaction drum to engage and compact soil, journaling means for journaling said drum for rotation on said second frame, vibratory means mounted on said second frame for vibrating said drum, and resilient isolation means interconnecting each side of the first frame, with the corresponding side member of the second frame to minimize transmission of vibration from said second frame to said first frame.
A vibratory compaction attachment for mechanical equipment, comprising a first frame, first mounting means on said first frame for connecting said first frame to a lift mechanism, second mounting means on said first frame for connecting said first frame to a tilt mechanism, a second frame, a compaction drum mounted for rotation on said second frame, vibratory means mounted on said second frame for vibrating said compaction drum, movement of said lift mechanism causing said compaction drum to move across the surface to compact the same, and a scraper blade connected to the first frame and movable on operation of said tilt mechanism from a non-operating position at a level above the lower extremity of said compaction drum to an operating position at a level beneath the lower extremity of said compaction drum.
