Abstract

Embodiments of the invention are directed to cutting tool assemblies, material-removing machines that include cutting tool assemblies, and methods of use and operation thereof. In some embodiments, the cutting tool assemblies described herein may be used in material-removing machines that may remove target material. For example, the cutting tool assemblies may include one or more superhard working surfaces and/or one or more shields.

Claims18

Dependent claims

A cutting tool assembly configured for mounting to a rotary drum assembly, the cutting tool assembly comprising:

a support block having a longitudinal centerline and including:
a mounting end exhibiting a first width and having a mounting front face, the mounting end being sized and configured to attach to the rotary drum assembly with the longitudinal centerline approximately aligned with a center of rotation of the rotary drum assembly;
a working end exhibiting a second width that is less than the first width and having a working front face substantially coplanar with at least a portion of the mounting front face, wherein the mounting front face extends from the working end a length greater than a length of the working front face;
and
at least one curved carve-out between the mounting end and the working end;
and
a cutting element secured to the working end of the support block, the cutting element having a working surface that includes a superhard material.

A cutting tool assembly, comprising:

a support block having a longitudinal centerline and including:
a mounting end exhibiting a first width and having a mounting front face, the mounting end being sized and configured to attach to a rotary drum assembly with the longitudinal centerline approximately aligned with a center of rotation of the rotary drum assembly;
a working end exhibiting a second width that is less than the first width and having a working front face substantially coplanar with at least a portion of the mounting front face and a seat distal to the mounting end, wherein the mounting front face extends from the working end a length greater than a length of the working front face;
and
a cutting element secured to the working end of the support block at least partially within the seat, the cutting element having a peripheral surface and a working surface that includes a superhard material, at least a portion of the peripheral surface being complementary to the seat.

2 more elements

A rotary drum assembly, comprising:

a drum body having a center of rotation;
and
at least one cutting tool assembly mounted to the drum body, the at least one cutting tool assembly including:
a support block having a longitudinal centerline approximately aligned with the center of rotation of the drum body, the support block including:
a mounting end exhibiting a first width and having a mounting front face, the mounting end being sized and configured to attach to the rotary drum assembly;
a working end exhibiting a second width that is less than the first width and having a working front face substantially coplanar with at least a portion of the mounting front face, wherein the mounting front face extends from the working end a length greater than a length of the working front face;
and
at least one curved carve-out between the mounting end and the working end;
and
a cutting element secured to the working end of the support block, the cutting element having a working surface that includes a superhard material.
