Description

BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to the field of dig tube attachments for vacuum trucks.

2. Description of Related Art

Various vacuum units and systems have been developed and used for picking up various types of material. In specific applications, for example, vacuum units have been used for excavation, for example, where removal of the excavated material was difficult to accomplish by other methods or where the excavation had to take place where damage to equipment, such as buried equipment, was a significant risk if alternative methods of excavation were used. Further, relatively large vacuum units have been mounted on a truck, and vacuum trucks have been driven to sites where excavation has been needed or where material needed to be picked up. For example, vacuum trucks have been used to excavate around buried utilities such as pipelines buried in the ground, where shutting down the pipeline would be a significant detriment, where excavation with other means, such as a back hoe, would have a greater risk of damaging the buried utility or pipeline, impose a safety risk to workers, or a combination thereof.

Still further, water has been used to break up material (e.g., earth) at an excavation site where the material is being picked up by a vacuum unit or system. Water systems have been mounted on vacuum trucks for this purpose, and have included, among other things, a water tank, water pump, water conduit that extends to the excavation site, and a water nozzle that is hand guided at the excavation site by an operator. Vacuum trucks with water systems have been referred to as hydrovac trucks, for example. Even further, air has been used to excavate material as a replacement for excavation water. Further still, excavation systems that used water often resulted in the material becoming overly wet (e.g., mud) which has made the material poorly suited to use immediately to backfill the excavation site when the work that required the excavation was completed. On the other hand, excavation systems that used air often created excessive dust and were not as effective as water at excavating certain types of material. Needs and potential for benefit or improvement exist for vacuum units and vacuum trucks that overcome these and other deficiencies of the prior art.

Current attempts have been made to address the needs of vacuum truck operators.

Also, singular words should be read as plural and vice versa and masculine as feminine and vice versa, where appropriate, and alternative embodiments do not necessarily imply that the two are mutually exclusive.

Reference is made to the figures of the invention included herein. A detailed description of the figures follows below.

Vacuum Truck

It is envisioned that the invention can articulate with any standard industry vacuum truck used by people of ordinary skill in the art to suction a liquid into the vacuum truck. The vacuum truck provides a pressurize liquid flow through the corrugated hoses or tubes. When articulated with the invention, this vacuum pressure suctions the liquid flow through the invention from the distal end of the primary attachment to its proximal end. In a preferred embodiment, the pressurized liquid flow would then also travel through the secondary attachment. It is also envisioned that the vacuum pressure of the invention will withstand the typical vacuum pressure utilized by people of ordinary skill in the art.

FIG. 1 is a general overview of the interaction between the primary attachment (1), a secondary attachment (i.e., debris box_ (2), and a vacuum truck (3), according to an embodiment of the present invention.

It is envisioned that the invention can articulate with any standard industry vacuum hose (5) commonly used with vacuum trucks. Such vacuum hoses vary by manufacturer but are typically corrugated tubing or pipe. They generally have an internal lumen diameter of between 6-8 inches while their outside structural diameters are generally 7-9½ inches wide.

It is envisioned that the secondary attachment (i.e., debris box) (2) would articulate with the vacuum hose at point proximal from the primary attachment (1) along the length of the vacuum hose and closer to the vacuum truck (3).

As a vacuum truck operator (4) would realize, the primary attachment articulates at the distal end of a vacuum hose (6).

Primary Attachment, as Assembled
