Benefits of technology

The present invention is a pneumatic wheel attachment for an excavator boom that provides a more efficient means for trench compaction. Compared to traditional methods, the present invention achieves better results with less effort. It is designed to operate in soft wet soils and does not clog with dirt or require additional hydraulic plumbing. The present invention is attached to the end of the excavator boom and rolls smoothly to achieve the desired compaction. It requires less passes with a minimum of two backfill lifts to achieve the standard desired compaction. The present invention is a pneumatic compaction wheel with a large foot print that engages and presses against a large surface area, thus decreasing the number of passes required to effectively compact a trench. The present invention is a wide and smooth rolling compaction with a large foot print that allows for efficient trench compaction. It is attached to the end of the excavator boom and uses a wheel yoke to hold and support the pneumatic compaction wheel, which allows for free rotation. The present invention is a pneumatic compaction wheel attachment for an excavator boom that provides a more efficient means for trench compaction.

Problems solved by technology

Trench compaction is required for areas in the ground where construction and other similar type of work has been implemented as the backfill is initially low in density and is susceptible to depression.
Additionally, wet and sticky soils have commonly been a problem for trench compaction with traditional means.
Pad-foot type steel compaction wheels clog with dirt and quickly become ineffective.
Vibratory plate compactors, while effective, are very expensive and require additional hydraulic plumbing on an excavator to operate the vibratory plate compactor.

Embodiment Construction

[0009]All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

[0010]The present invention generally relates to trench compaction mechanisms. More specifically, the present invention is a pneumatic wheel attachment for an excavator boom 16. The present invention provides a more efficient means for trench compaction when compared to traditional means such as vibratory plates and pad-foot steel compaction wheels.

[0011]Referring to FIG. 1, the present invention comprises a pneumatic compaction wheel 6, a wheel yoke 8, and a boom mounting assembly 1. The pneumatic compaction wheel 6 is a relatively large pneumatic wheel with a preferred width nearly equal to the width of the trench to be backfilled. The pneumatic compaction wheel 6 has a relatively large diameter that creates a smooth rolling compaction with a large foot print. The large foot print allows the present in...

Abstract

A pneumatic wheel attachment for an excavator boom that provides an efficient means for trench compaction. The pneumatic wheel attachment includes a pneumatic compaction wheel, a wheel yoke, and a boom mounting assembly. The pneumatic compaction wheel is a large tire with a large foot print. The wheel yoke holds and supports the pneumatic compaction wheel and includes a first leg, a second leg, and a connecting plate. The first leg and the second leg are positioned opposite to each other. The first leg is connected perpendicular to the connecting plate while the second leg is mounted perpendicular to the connecting plate. The pneumatic compaction wheel is rotatably mounted in between the first leg and the second leg with a rotation axis being oriented perpendicular to the first leg. The boom mounting assembly is adjacently connected to the connecting plate, opposite the first leg and the second leg.
