Edge cutting element for rotatable cutting drum
First Claim
1. A cutting element comprising:
- an arcuate base having a forward end, a rearward end, an arc-shaped inner radial surface adapted to be mounted to a surface of a rotatable cutting drum, and an outer radial surface, the arcuate base further defining a length, the length being bisected by a vertical reference plane that runs along the length, the arcuate base further including first and second sides, the first and second sides being parallel to the vertical reference plane, the outer radial surface defining three discrete planar mounting surfaces, a first of the planar mounting surfaces facing partially towards the first side and partially away from the second side, a second of the planar mounting surfaces facing partially away from the first side and partially towards the second side;
a tooth holder mounted to each of the planar mounting surfaces, the three tooth holders being configured to receive cutting teeth;
a cutting tooth mounted in each tooth holder, wherein there is a leading tooth adjacent the forward end of the arcuate base, a trailing tooth adjacent the rearward end of the arcuate base and exactly one intermediate tooth disposed between the leading tooth and the trailing tooth, each of the cutting teeth having a tooth tip;
wherein the tooth tip of the leading tooth defines a first tooth tip location, the first tooth tip location being offset in a first direction from the vertical reference plane;
wherein the tooth tip of the trailing tooth defines a second tooth tip location, the second tooth tip location being offset in a second direction from the vertical reference plane, the second direction being opposite from the first direction; and
wherein the tooth tip of the intermediate tooth defines a third tooth tip location relative to the vertical reference plane, the third tooth tip location being between the first and second tooth tip locations.

Abstract
A cutting element including an arcuate base having a first side, a second side, an outer radial surface, and an inner radial surface, the inner radial surface being configured to be mounted to a cutting drum. The cutting element also includes a plurality of tooth holders being mounted to the outer radial surface of the arcuate base, the tooth holders being configured to receive cutting teeth. Additionally, the cutting element includes a cutting tooth mounted in each tooth holder, wherein there is at least one leading tooth, and at least one trailing tooth, each of the cutting teeth being configured to cut through a dissimilar cutting plane, wherein each dissimilar cutting plane is parallel to one another.

8. A cutting arrangement comprising:
-
a cutting drum, the cutting drum having two side edges, a middle portion, and a rotational cutting direction; and at least three identically configured edge cutting elements defining a cutting edge, the cutting edge being adjacent a side edge of the cutting drum, each edge cutting element including; an arcuate base having a first side, a second side, an outer radial surface, and an inner radial surface, the inner radial surface being mounted to the cutting drum such that the at least three edge cutting elements are adjacently positioned on the cutting drum so that the forward end of one cutting element is adjacent the rearward end of an adjacent cutting element; a plurality of tooth holders being mounted to the outer radial surface of the arcuate base, the tooth holders being configured to receive cutting teeth; and a cutting tooth mounted in each tooth holder, wherein there is a leading tooth, a trailing tooth, and an intermediate tooth, each of the cutting teeth defining a respective tooth central axis, each tooth being mounted in a given tooth holder so as to be rotatable about the tooth central axis thereof, wherein the tooth central axis of the leading tooth is configured to point at least partially in a first axial direction away from the middle of the cutting drum and at least partially in the rotational cutting direction of the cutting drum, wherein the tooth central axis of the trailing tooth is configured to point at least partially in a second axial direction toward the middle of the cutting drum and at least partially in the rotational cutting direction of the cutting drum, wherein the tooth central axis of the intermediate tooth is configured to point at least partially in a third axial direction between the first axial direction and the second axial direction and at least partially in the rotational cutting direction of the cutting drum, and wherein each of the at least three edge cutting elements creates the same cutting pattern with their respective cutting teeth when the drum rotates in the rotational cutting direction. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
