Abstract
A cutting head for a mining machine includes a drum, a vane, and a cutting bit assembly positioned adjacent a surface of the vane. The drum includes a first end, a second end, and an outer surface, and the drum is rotatable about a drum axis. The vane is coupled to the outer surface of the drum and protrudes radially away from the drum axis. In some aspects, the vane includes a planar member extending at least partially around the drum axis and at least partially between the first end of the drum and the second end of the drum. In some aspects, the drum includes a plurality of planar walls extending between the first end and the second end.
Claims21
A cutting head for a mining machine, the cutting head comprising:
- a drum including a first end, a second end, and an outer surface, and the drum rotatable about a drum axis;
- a vane coupled to the outer surface of the drum and protruding radially away from the drum axis, the vane including a unitary planar member extending at least partially around the drum axis and from the first end of the drum to the second end of the drum;
- and
- a cutting bit assembly positioned adjacent a surface of the vane.
A cutting head for a mining machine, the cutting head comprising:
- a drum including a first end and a second end, the drum rotatable about a drum axis, the drum including a plurality of planar walls extending between the first end and the second end;
- a vane coupled to an outer surface of the drum, the vane protruding radially away and extending at least partially around the drum axis and extending from the first end of the drum to the second end of the drum;
- and
- a cutting bit assembly positioned adjacent a surface of the vane.
A cutting device for a rock cutting machine, the cutting device comprising:
- an arm supported for pivoting movement;
- a drum including a first end and a second end, the first end of the drum supported on the arm, the drum rotatable relative to the arm about a drum axis, the drum including a plurality of planar surfaces forming a polygonal profile;
- a vane coupled to the outer surface of the drum, the vane protruding radially away from and extending partially around the drum axis, the vane including a unitary planar member extending at least partially around the drum axis and from the first end of the drum to the second end of the drum;
- and
- a plurality of cutting bit assemblies secured to at least one of the drum and the vane, each of the cutting bit assemblies positioned adjacent a surface of the vane to facilitate loading of cut material onto the surface of the vane.
