Tractor Bucket Implement Attachment Device with Pivoting Swing Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching implements to tractor buckets are cumbersome, inefficient, and require significant time and effort for changeovers, with previous solutions often experiencing issues with secure attachment and support, especially for heavier implements.
Innovation Solution
The implement attachment device features a main receiver bar with receivers that allow implements to be removably pinned in place, adjustable to fit various bucket widths, and can be pivoted between a stowed and use-ready position, enabling rapid attachment and detachment without compromising the bucket's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical fasteners are used to rigidly affix implements directly to the bucket, then secure attachment is achieved, but substantial time and effort are required for manual affixation and disconnection
Solution Approach 1:
The device divides the attachment system into modular components: a receiver assembly with multiple receivers that can independently engage implement shanks, swing arms that pivot independently, and positioning pins that can be quickly inserted or removed. This segmentation allows rapid attachment by simply inserting pins rather than mechanically fastening entire assemblies.
Solution Approach 2:
The receiver assembly acts as an intermediary between the bucket and the implement. Instead of directly fastening the implement to the bucket, the receivers provide intermediate engagement points that simplify the connection process. The swing arms serve as another intermediary layer, providing a mechanical advantage system that reduces the effort needed for attachment while maintaining secure connection.
2Ease of operation
If implement adapter devices are supported on cantilever principles with clamping means, then attachment is simplified, but the clamping means loosen during use and permit separation
Solution Approach 1:
The swing arm design incorporates a counterbalancing mechanism where the weight and position of the implement are offset by the pivot point and arm configuration. This creates a self-stabilizing system where the implement's own weight helps maintain secure engagement rather than requiring active clamping forces that can loosen over time.
Solution Approach 2:
The system transitions from static clamping to dynamic engagement through the swing arm pivot mechanism. The arms can pivot to accommodate different implement weights and positions, automatically adjusting the engagement force. This dynamic adaptation prevents loosening by maintaining optimal contact pressure throughout operation.
3Reliability
If the implement attachment device is permanently mounted to the bucket, then attachment security is improved, but the bucket cannot be used in standard fashion between implement uses
Solution Approach 1:
The swing arms are designed to pivot between a stowed position (when not in use) and a deployed position (when supporting an implement). This dynamic positioning allows the bucket to function normally for particulate material handling when implements are not needed, while providing secure attachment capability when implements are required. The receivers remain permanently mounted but the swing arms can be repositioned as needed.
Solution Approach 2:
The attachment system is segmented into permanently mounted receivers and movable swing arms with implements. This segmentation allows the permanent component (receivers) to provide secure attachment points while the movable components (swing arms and implements) can be independently positioned or removed, preserving bucket versatility.
4Adaptability or versatility
If adjustable width is provided to fit various bucket widths, then adaptability is improved, but device complexity increases
Solution Approach 1:
The receivers are pre-positioned on the swing arms at fixed intervals, anticipating different bucket widths. During assembly, the swing arms are simply positioned at the appropriate spacing and secured, without requiring complex adjustment mechanisms. This pre-planning of receiver positions simplifies the adaptation process while maintaining versatility for different bucket sizes.
