BOOM TURRET FOR AN EXCAVATION VEHICLE AND METHOD THEREOF

Abstract:

A boom turret for a debris body. The boom turret includes an inlet defining an inlet axis and configured to couple to a hose. An outlet defining an outlet axis and configured to rotatably couple to the debris body. The inlet axis is substantially orthogonal to the outlet axis and a debris flow path is defined within the boom turret between the inlet and the outlet. A plate is disposed between the inlet and the outlet and has a surface at least partially defining the debris flow path through the boom turret. A nozzle is coupled to the plate and extends into the debris flow path. A pressure vessel is configured to hold a charge of pressurized fluid, and the pressure vessel is coupled in flow communication with the nozzle and selectively releases the charge of pressurized fluid through the nozzle to dislodge accumulated debris within the debris flow path.
