Abstract
A cutter head includes a first member, a cutting bit, and a second member. The first member includes a first end and a second end and includes a first mass. The cutting bit is coupled to the first member proximate the second end. The cutting bit includes a cutting edge rotatable about the axis. The second member is rotatable about the axis and includes a second mass eccentrically positioned with respect to the axis. Rotation of the second mass causes the first member and the cutting bit to oscillate.
Claims4
A cutter head for a mining machine, the mining machine including a frame and a boom movably coupled to the frame, the cutter head comprising:
- a first member including a first end and a second end;
- a cutting bit coupled to the first member proximate the second end, the cutting bit having a cutting edge and configured to engage a rock surface;
- a second member supported for rotation relative to the first member in an eccentric manner, rotation of the second member inducing an oscillating motion of the cutting bit;
- a fluid conduit extending through the first member and configured to be in fluid communication with a fluid source;
- and
- a plurality of nozzles positioned on the cutting edge, the nozzles in fluid communication with the fluid conduit.
