End of a moldboard positioned proximate a milling drum
View Patent ↗In one aspect of the present invention, the present invention is a system for removing aggregate from a paved surface. The system includes a motorized vehicle with a degradation drum that is connected to the underside of the vehicle. The degradation drum is enclosed by a milling chamber. The milling chamber is defined by having a plurality of plates, including a moldboard positioned rearward of the milling drum. The moldboard comprises an end that is disposed opposite the underside. The end comprises a section that is proximate the milling drum.
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 milling chamber further comprising an opening configured to receive an end of a conveyor;
picks secured to the degradation drum are configured to lift broken aggregate from a paved surface and allow the broken aggregate to fall onto the conveyor;
the conveyor is configured to remove the aggregate from the milling chamber;
the moldboard comprising an end disposed opposite the underside of the milling machine, and the end is configured provide a space underneath the moldboard and above the depth of cut;
the end comprising a section that is proximate the degradation drum.
2. The system of claim 1 , wherein the section is curved into the milling chamber.
3. The system of claim 1 , wherein the section generally follows a contour of the degradation drum.
4. The system of claim 1 , wherein the section is sharply sloped toward the degradation drum.
5. The system of claim 1 , wherein the moldboard comprises a plurality of nozzles disposed proximate the end of the moldboard and is in communication with a fluid reservoir through a fluid pathway.
6. The system of claim 5 , wherein the moldboard comprises a plurality of nozzles disposed proximate the end of the moldboard and is in communication with the fluid reservoir through the fluid pathway and a blower mechanism proximate the end of the moldboard and is in communication with a compressor through a gas pathway.
7. The system of claim 1 , wherein the moldboard comprises the blower mechanism disposed proximate the end of the moldboard and is in communication with a compressor through a gas pathway.
8. The system of claim 7 , wherein a portion of a gas is exhaust produced by the vehicle.
9. The system of claim 1 , wherein the section follows a radius of curvature of the degradation drum.
10. The system of claim 1 , wherein the end forms an 80-100 degree angle.
11. The system of claim 1 , wherein an angled portion of the section is angled and a curved portion is curved into the milling chamber.
12. The system of claim 1 , wherein the section is less than 0.25 inches above the bottom of the depth of cut.
13. The system of claim 1 , wherein the end is within one foot of the milling drum.
14. The system of claim 1 , wherein the moldboard comprises a plurality of nozzles disposed proximate a top of the moldboard and is in communication with the fluid reservoir through the fluid pathway.
15. The system of claim 1 , wherein the section elevates following the contour of the degradation drum.
16. The system of claim 1 , wherein a gas pathway retracts along with the section.
17. The system of claim 1 , wherein a fluid pathway retracts along with the section.
18. The system of claim 1 , wherein the section retracts from the paved surface.
19. The system of claim 1 , wherein the section is designed to push loose aggregate.
20. The system of claim 1 , wherein the section intentionally approaches the degradation drum.
