Claims
- 1. A system for tamping of material in a trench opening, comprising, a powered vehicle having a boom means coupled to said vehicle at one end and adjustably controlled therefrom and having an opposite end, bucket means coupled to said opposite end of said boom means, said bucket means consisting of a pair of buckets operating as a clamshell bucket, with one of said pair of buckets closing inside the other of said pair of buckets so as to provide a narrow tamping plate to fit into a narrow trench opening, vibrating means coupled to the end of said boom means and external of said bucket means for periodically vibrating said bucket means so as to assist in tamping and in compacting material dumped in said trench opening by said bucket means, and means positioned between said vibrating means and said boom means for absorbing and minimizing vibrations during the tamping and compacting of material placed by said bucket means in said trench opening.
- 2. A system for tamping of material in a trench opening as recited in claim 1, wherein said bucket means has a bottom having a rectangular configuration so that said bottom of said bucket means is flat for use as said tamping plate.
- 3. A system for tamping of material in a trench as recited in claim 1, and means for swivelling said bucket means to allow said tamping plate to fit into said narrow trench opening at any angular position relative to said narrow trench opening.
- 4. A system for tamping of material in a trench opening as recited in claim 3, and means for swivelling said bucket means 360 degrees with respect to the boom means to position the bucket means parallel to said trench opening.
- 5. A system for tamping of material in a trench opening as recited in claim 1, wherein said vibrator means is connected to a top side of said bucket means and there connected to the opposite end of said boom means, said system further consisting of a rubber cushion device to absorb vibrations from said vibration means.
- 6. A system for tamping of material in a trench opening as recited in claim 1, wherein said bucket means is constructed and adapted to retrieve, or grasp material for backfilling said trench opening and concurrently close one bucket inside the other.
- 7. A system for tamping of material in a trench opening as recited in 1, wherein said means for periodically vibrating said bucket means is positioned between the opposite end of said boom means and said bucket means, said system further incorporating a rubber cushion device to absorb vibrations from said vibration means.
