AI Technical Summary

Benefits of technology

The present invention is related to a mobile cleaning system that uses high pressure water to remove surfaces such as road paint stripes. The invention includes a rotatable grinder head that removes a majority of the surface material, making it easier to remove the underlying material using ultra high pressure fluid. The grinder head reduces the amount of ultra high pressure fluid required to remove surface materials. This results in faster and more efficient cleaning with minimal material remaining.

Problems solved by technology

A problem occurs when using only high pressure water to remove roadway markings if the markings are uneven.
In such instances the paint used for the marking may not have been applied evenly, worn evenly, or capable of being removed evenly.
Further, the paint surface may have been impacted through years of use, essentially compressing the paint into a hardened surface, which can add time during the removal process when only ultra-high pressure water is being used.
This can result in stripes repeated across the surface of the paint being cleaned, causing the cleaning operation to be either repeated or slowed accordingly.
In addition, in some areas road markings are applied one over the other as they wear, resulting in paint that is extremely thick and slower to blast away with water.

Embodiment Construction

[0019]While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described a presently preferred embodiment with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated.

[0020]Referring to the Figures, a grinder head 10 is illustrated depicting a spinner member 12 having a centrally disposed spindle 14 with a conduit 16 extending from an inlet 18 along a proximal end 20 to the spinner member 12 secured to the spindle 14 along a distal end 22. The conduit 16 adjoins a distribution conduit 24 formed from a channel 26 positioned substantially perpendicular to the conduit 16, feeding a plurality of finger channels 28, each ending in a threaded aperture 30. The inlet 18 is coupled to an ultra-high pressure fluid source between substantially 25,000 and 40,000 pounds per square inch. In the pre...

Abstract

A grinder head for high pressure mobile cleaning of roadways. The grinder head combines a rotating spinner member having polycrystalline diamond cutting tips which work in combination with ultra-high pressurized fluid for removing roadway stripes and the like matters from a roadway with damaging the underlying surface. The cutting tips having a polycrystalline diamond cutting material and are positioned along an outer rim of the spinner member in either a single or staggered position.
