摘要： 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.

摘要： A mining machine includes a frame, a boom supported for pivoting movement relative to the frame, and a cutter head pivotably coupled to the boom. The cutter head includes a housing, a cutter shaft coupled to the housing, a cutting disc, and an excitation mechanism. A second portion of the cutter shaft extends parallel to a cutter axis. The cutting disc is coupled to the second portion of the cutter shaft and is supported for free rotation relative to the cutter shaft about the cutter axis. The cutting disc includes a plurality of cutting bits defining a cutting edge. The excitation mechanism includes an exciter shaft and a mass eccentrically coupled to the cutter shaft. The excitation mechanism is coupled to the first portion of the cutter shaft. Rotation of the exciter shaft induces oscillating movement of the second portion of the cutter shaft and the cutting disc.

摘要： A rock excavating device includes a shaft and a cutting element. The shaft includes a first portion and a second portion connected to an end of the first portion. The first portion is rotatable about a first axis. The second portion extends along a second axis that is oblique with respect to the first axis. The cutting element includes a cutting edge. The cutting element is supported on the second portion and rotatable about the second axis. Rotation of the first portion of the shaft about the first axis changes the orientation of the second axis and the cutting element.

摘要： A machine for excavating rock includes a frame, a cutting device, and a boom. The cutting device includes a cutting disc having a cutting edge, and the cutting disc is rotatable about a cutting device axis. The boom supports the cutting device and includes a first end, a second end, and a boom axis substantially parallel to the cutting device axis. The boom further includes a first portion and a second portion. The first portion is coupled to the frame for rotation about a first pivot axis between a raised position and a lowered position. The second portion is coupled to the cutting device, and the second portion is pivotable about a second pivot axis between a raised position and a lowered position.
