Bucket Detachment Tool Pivoting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing detachment tools for concrete buckets, such as wedges suspended by a lever, often accumulate laitance, which hardens and causes the tool to push the concrete block backwards when lifted, requiring frequent cleaning and manual handling, posing safety risks and inefficiencies.
Innovation Solution
A bucket with a wedge-shaped detachment tool equipped with a mechanism that pivots and slides when lifted, allowing the wedge to rotate away from its vertical position, facilitating easier extraction of the concrete block and enabling safer, solo operation for cleaning behind the tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wedge-shaped detachment tool is used to extract concrete blocks from the bucket, then the concrete block extraction is facilitated, but laitance accumulates between the wedge and the front wall causing the tool to push the block backwards instead of extracting it smoothly
Solution Approach 1:
The detachment tool is designed to pivot dynamically during the extraction process. The tool rotates from an initial position where it pushes the concrete block away from the front wall to a final position where it lifts the block. This dynamic movement prevents laitance accumulation from causing backward pushing, as the tool's orientation changes during operation to maintain effective extraction force.
Solution Approach 2:
The mechanism performs preliminary action by rotating the detachment tool to a specific angular position before the actual lifting occurs. The stop element ensures the tool is properly positioned and the concrete block is pushed away from the front wall before the lifting force is applied, preventing the laitance accumulation problem from affecting the extraction effectiveness.
2Productivity
If the lever is tilted to lift the bucket for extraction, then the concrete block can be removed, but the accumulated laitance hardens and requires frequent manual cleaning which is dangerous and time-consuming
Solution Approach 1:
The detachment tool automatically performs the cleaning function during the extraction process. By pivoting the tool, the mechanism prevents laitance accumulation and uses the extraction motion itself to clear any accumulated material, eliminating the need for separate manual cleaning operations and reducing both time loss and safety risks.
Solution Approach 2:
The invention combines the extraction function and the cleaning function into a single integrated mechanism. The same pivoting motion that extracts the concrete block also prevents and clears laitance accumulation, merging two previously separate operations (extraction and cleaning) into one efficient process that reduces overall time requirements.
3Device complexity
If a simple suspended wedge is used for detachment, then the device structure remains simple, but the lifting force is not efficiently applied to the detachment of the concrete mass
Solution Approach 1:
The addition of the pivoting mechanism and stop element creates a dynamic system that efficiently transmits lifting force to the concrete block. The pivot point acts as a fulcrum, allowing the lifting force applied to the lever to be converted into effective detachment force, improving power efficiency while maintaining relatively simple device structure through the use of basic mechanical elements.
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
This solution ensures smoother concrete block extraction and reduces the need for frequent cleaning, enhancing operational safety and efficiency by applying the lifting force directly to the detachment of the concrete mass, allowing for easier maintenance without manual handling of heavy components.
Implementation Method 1
a wedge-shaped detachment tool 3 comprising a face 4 resting on the internal face of the front wall 5 of the bucket and an inclined face 6 facing the concrete block
Implementation Method 2
The wedge is suspended from the lever by a pin 7A located between the ends 8 and 9 of the lever. When the bucket is lifted with the lifting hook, the lever 7 pivots around the axis 8 of articulation and lifts the wedge
