Abstract
A microtrenching attachment for a work vehicle. The attachment includes a housing having an open bottom surface and first and second rotary cutting blades disposed within the housing in parallel planes. Each blade is mounted on a corresponding hub and configured to extend beyond the open bottom surface to cut two parallel trenches in a ground surface. A drive system rotates the blades, which may be powered by a single motor or by two independently controllable motors. The blades may be adjustable laterally to change the width between them, and thus a resultant trench width, as a separate excavation machine may be utilized to remove material between the parallel trenches, after the parallel trenches are uncovered.
Claims21
A microtrenching attachment for a work vehicle comprising:
- a housing;
- a first rotary cutting blade and a second rotary cutting blade, each mounted on a corresponding hub and disposed within the housing;
- a mounting assembly configured to couple the housing to the work vehicle;
- and
- a drive system configured to rotate the first rotary cutting blade and the second rotary cutting blade.
The microtrenching attachment of claim 11, in which the depth actuator comprises a hydraulic cylinder.
An attachment configured for use with a work vehicle, the attachment comprising:
- a housing having an open bottom surface, the bottom surface configured to contact a ground surface;
- a first rotary cutting blade disposed within the housing in a first plane;
- a second rotary cutting blade disposed within the housing in a second plane, wherein the first plane and the second plane are parallel;
- and
- a drive system configured to rotate the first rotary cutting blade and the second rotary cutting blade;
- wherein each of the first rotary cutting blade and the second rotary cutting blade are positioned to extend beyond the open bottom surface of the housing.
