Abstract
A cutting assembly for a mining machine includes a mount configured to move about a first axis relative to a chassis of the mining machine and a ranging arm coupled to the mount. The ranging arm is moveable relative to the mount. The cutting assembly includes a cutting head having a housing coupled to the ranging arm. The housing is moveable relative to the ranging arm. The cutting head includes a drum supported for rotation relative to the housing about a rotational axis, a plurality of cutting bits coupled to the drum, and at least one motor supported by the housing to drive the drum about the rotational axis.
Claims19
A cutting assembly for a mining machine, the cutting assembly comprising:
- a mount configured to move about a first pivot axis relative to a chassis of the mining machine;
- a ranging arm coupled to the mount, the ranging arm moveable relative to the mount along a first translational axis parallel to the first pivot axis;
- and
- a cutting head including,
- a housing coupled to the ranging arm, the housing moveable relative to the ranging arm along a second translational axis transverse to the first translational axis,
- a drum supported for rotation relative to the housing about a rotational axis,
- a plurality of cutting bits coupled to the drum, and
- at least one motor supported by the housing to drive the drum about the rotational axis.
A cutting assembly for a mining machine, the cutting assembly comprising:
- a mount configured to move about a first pivot axis relative to a chassis of the mining machine;
- a cutting head including,
- a housing,
- a drum rotatably coupled to the housing about a rotational axis,
- a plurality of cutting bits coupled to the drum, and
- at least one motor supported by the housing to drive the drum about the rotational axis;
- and
- a ranging arm coupled to the mount and supporting the cutting head for movement about the first pivot axis, the ranging arm moveable relative to the mount along a first translational axis, the first translational axis parallel to the first pivot axis,
- wherein the housing is moveable relative to the ranging arm about a second pivot axis, and wherein the second pivot axis is parallel to the first translational axis.
A cutting assembly for a mining machine, the cutting assembly comprising:
- a ranging arm configured to be coupled to a chassis of the mining machine;
- a cutting head including,
- a housing coupled to the ranging arm,
- a drum rotatably coupled to the housing about a rotational axis,
- a plurality of cutting bits coupled to the drum, and
- at least one motor supported by the housing to drive the drum about the rotational axis;
- and
- a mount coupled to the ranging arm, the mount configured to move about a first pivot axis relative to the chassis of the mining machine, the mount enabling movement of the drum about the first pivot axis,
- wherein the drum is moveable along a first translational axis relative to the mount, wherein the first translational axis is defined between the ranging arm and the mount, wherein the drum is moveable along a second translational axis relative to the mount, wherein the second translational axis is defined between the ranging arm and the housing,
- wherein the cutting assembly is configured to include at least four degrees of movement of the drum relative to the chassis.
