Excavation Bucket With Movable Trenching Blade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing excavation buckets are too wide for forming narrow trenches or small shapes, requiring additional equipment or manual labor for such tasks.
Innovation Solution
An excavation bucket assembly with a soil receiving opening and a movable soil gathering means, such as a concave trenching blade, that can be lowered through the opening to form trenches narrower than the bucket's width, using hydraulic power for operation and guided by tracks to maintain stability and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wide excavation bucket is used to efficiently clear large volume of material, then productivity is improved, but the bucket becomes too wide for forming narrow trenches requiring additional equipment
Solution Approach 1:
The bucket assembly incorporates a movable soil gathering means that can transition between positions. The blade is movable relative to the bucket body, allowing the configuration to change dynamically between wide clearing mode and narrow trenching mode, thus adapting to different作业 requirements while maintaining high productivity
Solution Approach 2:
The single bucket assembly performs multiple functions: it can clear wide areas using the full bucket width, and it can form narrow trenches by deploying the movable soil gathering means through the soil receiving opening. This multi-functionality eliminates the need for separate equipment for different trench widths
2Manufacturing precision
If the bucket width is reduced to form narrow trenches, then trench width precision is improved, but the clearing capacity for large areas decreases
Solution Approach 1:
The bucket assembly is segmented into functional components: the main bucket body for wide clearing and the movable soil gathering means for precise trenching. This segmentation allows each component to optimize its function - the bucket body maintains large clearing capacity while the movable blade provides precise trench width control when deployed
3Adaptability or versatility
If additional equipment is added for narrow trenching, then trenching capability is improved, but device complexity increases
Solution Approach 1:
The narrow trenching capability is merged into the existing bucket assembly by integrating the movable soil gathering means directly onto the bucket body. The blade is mounted on a movable support structure that is part of the bucket assembly, eliminating the need for separate trenching equipment and reducing overall system complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient formation of narrow trenches with minimal surface soil left at the edges, allowing for precise soil collection and increased operational efficiency without interrupting tractor movement.
Implementation Method 1
Power means, such as an hydraulic cylinder assembly, is supported by the upwardly extending back wall of the excavation bucket for moving the soil gathering means between its closed and open positions

AI summary
An excavation bucket assembly (10) is mounted to a tractor. A soil gathering trenching blade (48) is supported by an upwardly extending rear wall (18) and is movable down through a soil receiving opening (32) to scoop soil from beneath the ground wall (16) of the bucket, with the opening (32) being placed rearwardly of the front edge (30) of the ground wall, providing adequate space in the soil collection chamber (28) for receiving the excavated soil.
