Abstract
A milling machine includes a frame, a plurality of wheels or track members coupled to the frame, a moldboard movably coupled to the frame, a first rotor, and a second rotor. The first rotor is rotatably coupled to the frame. The second rotor is positioned to the rear of the first rotor and rotatably coupled to the moldboard.
Claims20
A milling machine, comprising:
- a frame;
- a plurality of wheels or track members coupled to the frame;
- a moldboard movably coupled to the frame such that the moldboard is movable vertically relative to the frame, wherein a bottom portion of the moldboard includes a scraper blade to engage with a milled ground surface;
- a first rotor, wherein the first rotor is rotatably coupled to the frame;
- and
- a second rotor positioned to the rear of the first rotor and rotatably coupled to the moldboard via one or more coupling elements, and wherein the second rotor is laterally movable relative to the moldboard.

A milling assembly, comprising:
- a moldboard;
- a first rotor, wherein the first rotor includes a plurality of cutting assemblies spaced apart by a first pitch;
- and
- a second rotor positioned to the rear of the first rotor, wherein the second rotor includes a plurality of cutting assemblies, wherein the plurality of cutting assemblies positioned on the second rotor are spaced apart by a second pitch that is smaller than the first pitch, wherein the second rotor is rotatably coupled to the moldboard, and wherein the second rotor is laterally movable relative to the moldboard via one or more hydraulic cylinders, and
- wherein the second rotor is driven by a coupling to the first rotor such that the second rotor is driven by a same power source that drives the first rotor.
2 more elements
A milling machine, comprising:
- a frame;
- a plurality of wheels or track members;
- a moldboard and one or more side doors forming a milling chamber;
- a first rotor positioned within the milling chamber, wherein the first rotor is rotatably coupled to the frame;
- and
- a second rotor positioned to the rear of the first rotor and forward of the moldboard, wherein the second rotor is rotatably positioned within the milling chamber, wherein the second rotor is rotatably coupled to the moldboard via one or more coupling elements, wherein the moldboard is vertically movable such that a height of the second rotor is adjustable relative to the first rotor, and wherein the second rotor is laterally movable within and out of the milling chamber via a supporting hydraulic cylinder.
