Multiple milling drums secured to the underside of a single milling machine
View Patent ↗In one aspect of the present invention, a motorized vehicle comprises a vehicle frame. The vehicle frame comprises translatable elements. The frame comprises a forward end and a rearward end. The invention comprises of a first rotary degradation drum that is connected to the underside of the frame. The invention comprises of at least a second rotary degradation drum also connected to the underside of the frame and rearward of the first rotary degradation drum.
1. A motorized vehicle, comprising:
a vehicle frame comprising translatable elements;
the frame comprises a forward end and rearward end;
a first rotary degradation drum connected to an underside of the frame;
at least a second rotary degradation drum also connected to the underside of the frame and rearward of the first rotary degradation drum; and
at least one of the first and second rotary degradation drums is in communication with an actuating mechanism adapted to move the rotary degradation drum in a horizontal, vertical, transverse, diagonal, and pivotal direction relative to the motorized vehicle.
2. The vehicle of claim 1 , wherein at least one of the first and second rotary degradation drums are configured to translate laterally with respect to a length of the frame.
3. The vehicle of claim 1 , wherein the first and second rotary degradation drums are configured to degrade a formation at different depths.
4. The vehicle of claim 1 , wherein the first and second rotary degradation drums are capable of expanding outwards such that collectively they mill a path wider than the milling machine.
5. The vehicle of claim 1 , wherein at least one of the first and second rotary degradation drums comprises a plurality of cutting elements enhanced with polycrystalline diamond.
6. The vehicle of claim 1 , wherein a degradation zone in a direction of travel occurs about the rotary axis which is perpendicular to the underside of the motorized vehicle.
7. The vehicle of claim 1 , wherein the first rotary degradation drum and the second rotary degradation drum are configured to degrade a formation into aggregate.
8. The vehicle of claim 1 , wherein a conveyor belt is attached to a milling chamber.
9. The vehicle of claim 8 , wherein a conveyor belt is encased by a chute with open ends.
10. The vehicle of claim 1 , wherein liquid jets are attached to the underside of the vehicle to remove aggregate from the rotary degradation drums.
11. The vehicle of claim 1 , wherein a hydraulic mechanism is configured to translate at least one of the first and second rotary degradation drums.
12. The vehicle of claim 1 , wherein the first and second rotary degradation drums are configured to translate laterally along a track attached to the underside.
13. The vehicle of claim 1 , wherein the first and second rotary degradation drums are configured to operate simultaneously.
14. The vehicle of claim 1 , wherein the first rotary degradation drum and the second rotary degradation drum are encased in separate milling chambers.
15. The vehicle of claim 1 , wherein the first and second rotary degradation drums are encased in the same milling chamber.
16. The vehicle of claim 1 , wherein the second rotary degradation drum is a split drum with a single axle.
17. The vehicle of claim 16 , wherein a milling chamber housing the split drum is expandable.
18. The vehicle of claim 17 , wherein the split rotary degradation drum comprises portions that are configured to extend beyond a side of the motorized vehicle.
19. The vehicle of claim 1 , wherein the second rotary degradation drum is positioned laterally to a third independent rotary degradation drum.
