  • CUTTER HEAD FOR MINING MACHINE
    Publication number: 20240125232
    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.

  • Method for removing material from a rock wall
    Patent number: 11725512
    Abstract: A method for removing material from a rock wall. The method includes moving a cutting edge through the rock wall to create a first slot in the rock wall, moving the cutting edge through the rock wall to create a second slot in the rock wall, the second slot being separated from the first slot by an uncut portion, the uncut portion defining a base surface attached to the wall, cutting a notch into the base surface of the uncut portion, and applying a force on the uncut portion to break the uncut portion away from the wall.

  • CUTTER HEAD FOR MINING MACHINE
    Publication number: 20220349306
    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.
