Excavator Bucket Grading Blade Pivot Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for attaching grading blades to excavators are slow, effortful, and require permanent modifications, limiting the bucket's usability and precision due to the inability to pivot with the ground's contour.
Innovation Solution
A coupling system that allows quick attachment and detachment of a grading blade to an excavator bucket using a rectangular metal coupling with a hollow tube and pivot point, enabling the blade to pivot with the ground's contour.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed means such as welding or bolting are used to attach a grading blade to an excavator bucket, then the blade can be securely attached, but the installation is slow and effortful and requires permanent modifications to the bucket
Solution Approach 1:
The attachment system is divided into separate modular components: a coupling device with mounting brackets that attaches to the bucket, and a grading blade that attaches to the coupling device. This segmentation allows each component to be independently manufactured and quickly assembled without permanent modifications to the bucket, resolving the contradiction between secure attachment and quick installation.
Solution Approach 2:
The coupling device is pre-assembled with mounting brackets and attachment mechanisms before being brought to the installation site. This preliminary preparation eliminates the need for complex on-site assembly or permanent modifications to the bucket during installation, enabling quick and secure attachment without time loss.
2Stability of the object's composition
If fixed means are used to attach a grading blade to an excavator bucket, then the blade remains stable, but the bucket's structure is changed and its usefulness is limited
Solution Approach 1:
The coupling device acts as an intermediary segment between the bucket and the grading blade, featuring a standardized mounting interface that can accommodate different blade types. This segmentation allows the bucket to maintain its original structure and versatility while providing stable attachment for various grading blades through the universal coupling mechanism.
Solution Approach 2:
The coupling device is designed with universal mounting brackets that can attach to different bucket types and configurations. This multi-functionality allows a single coupling device to work with various excavator buckets and blade types, maintaining bucket versatility while providing stable, repeatable attachment across different applications.
3Strength
If a grading blade is attached by fixed means to an excavator bucket, then the attachment is rigid, but the blade cannot pivot with the ground contour reducing precision
Solution Approach 1:
The coupling device incorporates a pivot joint that allows the grading blade to dynamically rotate and adjust its angle relative to the bucket. This dynamic capability enables the blade to pivot with the ground contour while maintaining a strong, secure attachment through the robust coupling mechanism, resolving the contradiction between rigid strength and adaptive precision.
Solution Approach 2:
The coupling device serves as an intermediary mechanism between the rigid bucket and the ground-contacting blade. It provides a pivot joint that mediates between the fixed bucket position and the need for blade adjustment, allowing the blade to rotate and follow ground contours while maintaining secure attachment strength through the coupling's mechanical connection.

AI summary
A removeable attachment to an excavator bucket allowing for multi-purpose use of a single excavator without the need for lengthy modification or installation. The preferred embodiment is a grading blade attachment. The invention attaches to an excavator bucket by drilling holes into the bucket, inserting the coupling device of the invention between the bucket, and inserting a metal pin through the bucket and coupling device. The metal pin is secured by a lynch pin when installed. The attachment also has a circular piece of metal, allowing for the attachment to pivot with the contour of the ground during use and allowing more accurate use of construction cleanup equipment while reducing damage to landscape.
