| 摘要 |
<p>The invention concerns a soil compaction machine (10) which comprises a wheeled carriage (40) and spaced apart, out-of-round compactor masses (12) suspended relative to the carriage. The periphery of each mass (12) is defined by spaced apart salient points (14) and intermediate compacting faces (16) between the salient points. The salient points and compacting faces are arranged such that when the mass (12) is rolled over a soil surface it alternately rises up on each salient point (14) in turn, thereby storing potential energy, and then descends onto the following compacting face (16) to deliver the stored energy to the soil to compact it. In accordance with the invention, the masses (12) are independently suspended relative to the carriage (40).</p> |
