Multi-part Sector-shaped Stirring Element for Agricultural Spreader
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural spreader stirring devices require laborious processes for replacing or adjusting stirring elements due to their one-piece design, necessitating partial dismantling of the agitator shaft and increased risk of contamination and safety hazards.
Innovation Solution
A multi-part, preferably two-part, sector-shaped stirring element design allows for easy assembly and disassembly without dismantling the agitator shaft, with sector-shaped sections that can be connected and disconnected easily, reducing the need for tools and minimizing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one-piece stirring elements are used on the agitator shaft, then the stirring structure is simple, but the replacement and adjustment of stirring elements becomes laborious and time-consuming
Solution Approach 1:
The stirring element is divided into multiple sector-shaped sections that can be independently assembled and disassembled. Each section can be separately removed from the agitator shaft without dismantling the entire stirring element, enabling quick replacement and adjustment while maintaining a relatively simple overall structure.
2Strength
If stirring elements are fastened with bolts and screw connections, then the connection is secure, but the replacement process requires tools and becomes more complex
Solution Approach 1:
The sector-shaped sections are designed with self-latching mechanisms that enable secure attachment to the agitator shaft without requiring external fastening tools. The sections can be manually assembled and disassembled by hand, eliminating the need for bolts, screws, or other fastening tools while maintaining a secure connection during operation.
3Ease of repair
If the agitator shaft must be partially dismantled for stirring element replacement, then individual elements can be accessed, but the risk of contamination and safety hazards increases
Solution Approach 1:
The stirring element is segmented into multiple sections that can be independently removed from the agitator shaft. This allows individual sections to be accessed and replaced without dismantling the entire shaft or exposing the operator to hazardous rotating components, thereby reducing contamination risk and improving safety while maintaining ease of repair.
4Adaptability or versatility
If multiple stirring elements are used to handle varying material properties, then adaptability is improved, but the complexity of assembly and disassembly increases
Solution Approach 1:
The stirring element is divided into multiple identical or varied sector-shaped sections that can be independently assembled on the agitator shaft. This segmentation allows the operator to quickly configure the number and arrangement of stirring sections according to different material properties, achieving high adaptability without increasing assembly complexity since each section uses the same simple attachment mechanism.
