Foam Configured to Suppress Dust on a Surface to be Worked
In one aspect of the invention, a system for removing aggregate from a natural or man-made surface includes a vehicle with a frame and a conveyor. The conveyor has an intake end and an output end. An excavation drum is connected to an underside of the frame and is enclosed within an excavation chamber, which is defined by a front plate, side plates, and a moldboard. The intake end of the conveyor that protrudes into the excavation chamber is configured to remove the aggregate from the excavation chamber, and a dust suppressant nozzle is configured to apply a foamed dust suppressant to the natural or man-made surface prior to being degraded by the excavation drum.
1 . A system for removing aggregate from a working surface, comprising:
an excavation drum connected to a vehicle and enclosed within an excavation chamber;
a jet cutting nozzle attached to the vehicle and angled to jet fluid towards the working surface proximate the excavation drum and degrade the working surface prior to being degraded by the excavation drum.
2 . The system of claim 1 , wherein the nozzle is a spray nozzle.
3 . The system of claim 2 , wherein the nozzle is a hydraulic nozzle.
4 . The system of claim 2 , wherein the nozzle is an air-assisted nozzle.
5 . The system of claim 2 , wherein the nozzle is an ultrasonic nozzle.
6 . The system of claim 1 , wherein the nozzle sprays the working surface within the excavation chamber.
7 . The system of claim 1 , wherein the nozzle is disposed within the excavation chamber.
8 . (canceled)
9 . The system of claim 1 , further comprising a conveyor with an intake end within the excavation chamber and an output end; wherein the excavation drum lifts aggregate within the excavation chamber and allows the aggregate to fall onto the intake end of the conveyor that protrudes into the excavation chamber.
10 . The system of claim 1 , wherein the fluid is a liquid dust suppressant that comprises water and a dust binding agent.
11 . The system of claim 1 , wherein the vehicle comprises a mechanism for applying the fluid, the mechanism comprises the nozzle, at least one fluid line, a pump, and a fluid tank.
12 . The system of claim 11 , wherein the pump pressurizes the fluid.
13 . The system of claim 11 , wherein the mechanism for applying the fluid comprises an air compressor to pressurize the liquid.
14 . The system of claim 11 , wherein the mechanism for applying the fluid comprises a plurality of nozzles.
15 . (canceled)
16 . (canceled)
17 . The system of claim 1 , wherein the nozzle comprises a valve to control flow and pressure of the fluid.
18 . The system of claim 1 , wherein the nozzle floods the working surface preceding the excavation drum with the fluid.
19 . (canceled)
20 . (canceled)
21 . The system of claim 1 , wherein the nozzle sprays the working surface outside the excavation chamber.
22 . The system of claim 1 , wherein the nozzle is disposed outside the excavation chamber.
23 . A system for removing aggregate from a surface, comprising:
a vehicle comprising a frame and a conveyor;
the conveyor comprises an intake end and an output end;
an excavation drum is connected to an underside of the frame and is enclosed within an excavation chamber, the excavation chamber is defined by a front plate, side plates, and a moldboard;
the intake end protrudes into an opening of the excavation chamber to remove the aggregate from the excavation chamber;
a nozzle is disposed within the excavation chamber between the front plate and the excavation drum to apply moisture to the surface prior to being degraded by the excavation drum;
wherein the nozzle is a spray nozzle to spray the surface prior to being degraded by the excavation drum; and
wherein the nozzle is an ultrasonic nozzle.
