Segmented Adhesion Suppressing Member for Construction Bucket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in effectively suppressing soil adhesion to construction machinery work tools, particularly in curved and welded portions of buckets, which complicates mounting, maintenance, and repair processes.
Innovation Solution
An adhesion suppressing member is introduced, comprising a plate-shaped metal material bonded to a resin material with water-repellent properties. This member is installed on predetermined portions of the work tool, such as the bottom and side plate portions of a bucket, to form part of the tool's surface in contact with the work piece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a lining body or coating film is provided on the entire inner surface of the bucket, then soil adhesion is suppressed, but mounting processability deteriorates due to difficulty in achieving close contact with curved and welded portions
Solution Approach 1:
The invention divides the adhesion suppressing member into multiple separate plates (first adhesion suppressing member for the bottom plate portion, second adhesion suppressing member for the side plate portion, etc.) rather than using a single continuous lining body. This segmentation allows each plate to be independently mounted on flat surfaces, avoiding the need to achieve close contact with curved and welded portions, thereby improving mounting processability while still suppressing soil adhesion on the areas where plates are installed.
Solution Approach 2:
The invention applies adhesion suppressing members only to specific local areas (bottom plate portion and side plate portions) rather than covering the entire inner surface including curved and welded portions. This local application approach maintains the benefit of soil adhesion suppression on critical flat surfaces while avoiding the mounting difficulties associated with complex geometries.
2Object-affected harmful factors
If a lining body or coating film is provided on the entire inner surface of the bucket, then soil adhesion is suppressed, but repairability deteriorates as broken portions require complete removal and long excavation interruption
Solution Approach 1:
By dividing the adhesion suppressing system into multiple separate plate members, the invention enables localized repair. When one plate becomes broken or worn, only that specific plate needs to be removed and replaced, while other plates remain in place. This eliminates the need to remove the entire lining body and allows quick repair without long excavation interruptions.
Solution Approach 2:
The adhesion suppressing plates are designed as replaceable components that can be easily removed and replaced when worn or damaged. This approach treats the adhesion suppressing function as a consumable element that can be quickly swapped out, minimizing downtime and repair complexity compared to repairing a permanent continuous lining.
3Productivity
If the bucket is swung or impact applied to shake out adhesion residual soil, then work efficiency is maintained, but noise and vibration increase causing environmental concerns
Solution Approach 1:
The invention converts the harmful adhesive property of soil into a beneficial non-adhesive surface by applying water-repellent adhesion suppressing plates. This prevents soil from sticking to the bucket interior, allowing soil to be discharged cleanly without requiring aggressive shaking or impacting operations that generate noise and vibration.
Solution Approach 2:
The adhesion suppressing plates enable the bucket to self-clean during normal operation. By preventing soil adhesion in the first place, the bucket surface automatically releases soil without requiring external cleaning actions like swinging or impacting, thereby maintaining work efficiency while eliminating harmful noise and vibration.
4Productivity
If automatic driving continues for a certain period, then productivity is improved, but safety deteriorates as manual cleaning requires worker approach to moving machinery
Solution Approach 1:
The adhesion suppressing plates enable the bucket to automatically prevent soil accumulation during continuous automatic driving operations. The non-adhesive surface ensures soil is discharged completely without manual intervention, allowing automatic driving to continue indefinitely without safety risks to workers who would otherwise need to approach moving machinery for cleaning.

AI summary
Provided is an adhesion suppressing member that is configured to suppress a work piece from adhering to a work tool of a construction machinery. The adhesion suppressing member is formed in a plate shape and includes, on a front surface thereof, a resin material having a water repellent property. The adhesion suppressing member is installed at a predetermined portion of the work tool such that the front surface forms a part of a surface of the work tool held in contact with the work piece.
