Plurality of liquid jet nozzles and a blower mechanism that are directed into a milling chamber
View Patent ↗In one aspect of the present invention a system is disclosed for removing loose aggregate from a paved surface. The system comprises a motorized vehicle that has a degradation drum connected to the underside of the vehicle. The degradation drum is enclosed by a milling chamber. The milling chamber is comprised of a plurality of plates, including a moldboard that is positioned rearward of the degradation drum. The moldboard has an end that is disposed opposite the underside. The end has a plurality of liquid jet nozzles and a blower mechanism that are directed into the milling chamber.
1. A system for removing aggregate from a paved surface, comprising:
a vehicle comprising a degradation drum connected to an underside of the vehicle;
the degradation drum is enclosed by a milling chamber;
the milling chamber being defined by a plurality of plates including a moldboard positioned rearward of the degradation drum;
the moldboard comprising an end disposed opposite the underside; and
the end comprising a plurality of liquid jet nozzles and a blower mechanism that are directed into the milling chamber;
wherein the plurality of liquid jet nozzles and blower mechanism are positioned to push aggregate in a direction of travel.
2. The system of claim 1 , wherein the blower mechanism is located rearward of the plurality of liquid jet nozzles.
3. The system of claim 1 , wherein the blower mechanism expels gas that contacts the paved surface rearward of where liquid from the nozzles is configured to contact the paved surface.
4. The system of claim 1 , wherein the plurality of liquid jet nozzles are configured to eject liquid into the milling chamber.
5. The system of claim 1 , wherein the nozzles is configured to force liquid under the end of the moldboard.
6. The system of claim 1 , wherein the plurality of liquid jet nozzles is in communication with a fluid reservoir through a fluid pathway.
7. The system of claim 1 , wherein the blower mechanism is in communication with a compressor or air blower through a gas pathway.
8. The system of claim 1 , wherein the plurality of liquid jet nozzles is rigidly fixed to at least a portion of the moldboard.
9. The system of claim 1 , wherein the fluid pathway is flexibly coupled to at least a portion of the moldboard.
10. The system of claim 1 , wherein the blower mechanism is rigidly fixed to at least a portion of the moldboard.
11. The system of claim 1 , wherein the gas pathway is flexibly coupled to at least a portion of the moldboard.
12. The system of claim 1 , wherein the blower mechanism comprises an underside configured to contact the paved surface.
13. The system of claim 1 , wherein a heater is configured to heat the liquid passing through the fluid pathway.
14. The system of claim 1 , wherein the gas pathway is configured to receive exhaust from an engine of the milling machine.
15. The system of claim 1 , wherein the moldboard is curved into the milling chamber.
16. The system of claim 1 , wherein moldboard is substantially flat and slightly angled into the milling chamber.
17. The system of claim 1 , wherein the plurality of liquid jets span at least a majority of a width of the moldboard.
18. The system of claim 1 , wherein the blower mechanism spans at least a majority of a width of the moldboard.
19. The system of claim 1 , wherein the blower mechanism and the liquid jets may be formed in a unithary piece.
