Embodiment Construction

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0016] The illustrated multi-faceted compaction roll 10 has a central hub 12 located on a central axis 14 , and peripheral compaction faces 16 connected to the hub by radial spokes 18 . The compaction surface 16 is defined by six inflection points 20 that are equiangularly spaced and equidistant from the central axis 14 and by six intermediate compaction work surfaces 22 extending between the inflection points. The compacting faces 22 are identical to each other and have a smooth convex curvature symmetrical with respect to the radial bisector of the two inflection points 20 and extending between the two inflection points. For example, the compaction face 22.1 is symmetrical with respect to the radial bisector 24 of the two inflection points 20.1.

[0017] The inflection point 20 and working face 22 of the compaction face 16 are formed by curved wear plates 26 and 28 mounted to the ends of the spokes 18, respectively. ...

Abstract

The invention concerns a soil compaction roller (10) and a soil compaction machine of which the roller (10) forms part. The roller (10) comprises a multi-sided, out-of-round, peripheral compacting surface (16) which can roll over a soil surface which is to be compacted. The compacting surface (16) is defined by a series of angularly spaced salient points (20) and a corresponding series of compacting faces (22). Each compacting face (22) is outwardly convex in shape and extends continuously between two adjacent salient points (20). When the roller (10) is operative with the compacting surface (16) rolling over the soil surface, the roller rises up on each salient point (20) in turn, storing potential energy, and thereafter rolls downwardly onto the succeeding compacting face (22) to transmit the stored potential energy to the soil surface to compact it. The instantaneous centre of rotation of the compacting surface (16), where it contacts the soil surface during rolling, moves continuously about substantially the full extent of the compacting surface.

Description

Background of the invention [0001] The invention relates to a compacting roller. [0002] Traditionally, soil compaction is achieved with the aid of large mass circular or vibrating rollers. More recently, impact compactors such as those described in US Patent Specification No. 2,909,106 have been used for soil compaction work. Impact compactors have been shown to achieve high levels of soil compaction at depths below the surface, but in some cases, where soils in shallower surface areas must be compacted, they may Not very effective. Depending on soil conditions, the impact rollers of an impact compactor have a tendency to merely disturb the surface layer without compacting it effectively. [0003] The impact rollers of conventional impact compactors may also have a tendency to create localized subsidence in the soil surface requiring subsequent leveling operations. They can also create shock loads on the pulling tractor and the soil, and have lower operating speeds. Su...
