US 2026/0266138 A1 · EARTH CUTTING APPARATUS NOZZLES AND RELATED METHODS

Abstract

A cutting apparatus for cutting earth can utilize a plurality of nozzles. Each nozzle can include a plurality of curved passageways defined in the body of the nozzle to direct fluid through the nozzle for being ejected from outlets of the nozzle so the fluid can contact debris being cut by a cutting member to help direct that debris away from the cutting member, help minimize dust formation during cutting operations, and/or help cool the cutting member. In some embodiments, the fluid that can be output from outlets of the nozzle can be a liquid that can experience reduced friction as it passes through the nozzle to provide a fluid flow that is more efficiently passable through the nozzle and/or able to pass through the nozzle so the output fluid can be output at higher velocities.

Dependent claims

A cutting apparatus comprising:

a plurality of nozzles connectable to an earth cutting member that is moveable to cut into ground;
each of the nozzles having:
a body, the body defining a fluid intake chamber adjacent a first end of the body, a plurality of outlets defined in a second end of the body that is opposite the first end of the body, and a plurality of fluid flow passageways extending from the fluid intake chamber to the outlets such that each of the fluid flow passageways extends from the fluid intake chamber to a respective one of the outlets, the fluid intake chamber having a mouth defined at the first end of the body;
the body defined such that at least one of the fluid flow passageways has an intermediate segment that has a curve or bend that extends about a pre-selected angle of curvature, the intermediate segment being located between the fluid intake chamber and the outlet to which the fluid flow passageway extends.
