Embodiment Construction

[0030] An aspect of the present invention is to provide an improved knife assembly in the sense that it can include various types of transport such as linear, circular, etc. carrying cutting elements, and in the sense that it is capable of cutting through extremely hard materials and such as Soft material for sandy loams and is versatile in the sense of not needing to change cutting elements frequently.

[0031] Embodiments of the present invention provide an improved knife assembly capable of severing extremely hard materials with a high degree of cutting efficiency and thus relatively fast cutting speeds, such as at speeds as high as 6 to 12 inches per minute or more Cutting reinforced high-strength concrete of various thicknesses. In this regard, one aspect of the present invention provides such a cutting assembly that produces a unique cutting action that fragments material by subjecting it primarily to tension rather than compression.

[0032] In one embodiment, the pres...

Abstract

A universal cutter assembly comprises a transport device carrying a plurality of freewheeling cutting elements mounted to freely rotate about an axis, wherein the axis is canted about two angles with respect to the surface being cut and a line of action imparted by the transport device.

Description

[0001] Cross References to Related Applications [0002] This patent application claims U.S. Provisional Patent Application No. 61 / 934,476, filed January 31, 2014, U.S. Provisional Application No. 61 / 947,749, filed March 4, 2014, and U.S. Provisional Application No. 61 / 947,749, filed June 10, 2014. Priority of Application No. 62 / 010,171. technical field [0003] The present invention relates generally to cutter assemblies, and more particularly to cutter assemblies for trenching machines, drilling machines, profiling machines, and similar equipment for cutting or grinding rock and earth. Background technique [0004] One of the difficulties with current cutter assemblies for trenchers is that the cutting elements are generally not suitable for digging through hard and soft materials without changing the cutting elements. In addition, cutting elements are often incapable of penetrating certain extremely hard materials such as concrete, rocks, tree stumps, frozen ground, and ...
