Abstract
A universal cutter assembly comprising a transport device carrying a plurality of freewheeling cutters mounted to freely rotate about an axis, where the axis is canted about two angles with respect to the surface being cut and a line of action imparted by the transport device.
Claims22
A cutter assembly for earthen materials comprising:
- a transport device carrying a plurality of cutting stations so as to drive the cutting stations in a direction of movement, each cutting station including at least one freewheeling cutter that is freely rotatable about a respective axis of rotation, wherein:
- the respective cutter axis of rotation of at least a portion of the freewheeling cutters is canted by a tilt angle toward a plane of the surface being cut and is also canted by a side angle toward the direction of movement;
- each freewheeling cutter includes:
- (a) a cutting surface comprising cutter points that point outward from the respective cutter axis of rotation, the cutter points being disposed at an angle relative to the cutter axis of rotation and arranged around a circumference of the cutting surface, and (b) a cutter body encasing a base of each cutter point so each base of each cutter point is entirely surrounded by the cutter body.

- a transport device carrying a plurality of cutting stations so as to drive the cutting stations in a direction of movement, each cutting station including at least one freewheeling cutter that is freely rotatable about a respective axis of rotation, wherein:
- the respective cutter axis of rotation of at least a portion of the freewheeling cutters is canted by a tilt angle toward a plane of the surface being cut and is also canted by a side angle toward the direction of movement;
- each freewheeling cutter includes a cutting surface comprising individual teeth that point outward from the respective cutter axis of rotation, wherein the individual teeth are arranged around a circumference of the cutting surface and each individual tooth has an exposed end that points outward from the respective cutter axis of rotation and forms a cutter point and a base of the cutter point that is encased in a body of the cutter so as to be entirely surrounded by the cutter body, the cutter points being disposed at an angle between 15° and 75° relative to the cutter axis of rotation.
A cutter assembly for earthen materials comprising:
- a transport device carrying a series of cutting stations so as to move the cutting stations in a direction of movement such that the cutting stations cut through a material and form a cut profile, each cutting station including at least one freewheeling cutter that is freely rotatable about a respective axis of rotation, wherein:
- the respective cutter axis of rotation of each of at least a portion of the freewheeling cutters is disposed at an angle relative to the direction of movement imparted by the transport device and is disposed at an angle relative to a surface being cut;
- and
- the freewheeling cutters in each cutting station in the series have a different lateral position and a different depth so as to form a cut profile with a tapered shape including a deeper center and shallower sides, wherein each freewheeling cutter includes:
- (a) a cutting surface comprising cutter points that point outward from the respective cutter axis of rotation, the cutter points arranged around a circumference of the cutting surface, and (b) a cutter body encasing a base of each cutter point so each base of each cutter point is entirely surrounded by the cutter body.
