Wide-End Trencher Boom Configurable Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trenching and surface planing machines are limited to a single excavating width, making them inefficient for varying trenching tasks and requiring high power consumption for wide trench excavation.
Innovation Solution
A trencher design that can be converted between two trenching configurations, utilizing a trenching boom with a trenching chain and drum sections to excavate both undercut and non-undercut regions, allowing for efficient excavation of wide trenches with lower power requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-width trenching machine is used, then the device structure is simple, but the adaptability to different trenching tasks is limited
Solution Approach 1:
The trencher boom is designed with dynamic configurability, allowing it to be adjusted between different trenching widths through movable components such as the trench widener assembly that can be positioned at multiple locations along the boom structure
Solution Approach 2:
The trencher boom structure incorporates multiple functional capabilities within a single device, enabling it to perform both narrow and wide trenching operations, as well as provide support functions through the boom structure itself, thereby replacing the need for multiple specialized machines
2Use of energy by moving object
If a traditional single-chain trencher is used for wide trench excavation, then the device structure is simple, but the power consumption is high
Solution Approach 1:
The cutting function is segmented between the trenching chain and drum sections, allowing the chain to handle the main trenching while drum sections assist with undercut removal, distributing the workload and reducing the power burden on a single cutting system
Solution Approach 2:
The boom structure is used to preliminarily break up and remove overburden material before the trenching chain engages, reducing the amount of material the chain must cut through and thereby reducing overall power consumption

AI summary
A trencher that is convertible between first and second trenching configurations so that when the trencher is in the first trenching configuration, a trencher boom includes a first trenching portion at the distal end of the boom and a second trenching portion that extends along a longitudinal axis from the first trenching portion toward the proximal end. The first trenching portion defines a first trench width, and the second trenching portion defines a second trench width. The first trench width is larger than the second trench width. The second trenching portion has a greater length measured along the longitudinal axis as compared to the first trenching portion.
