Ripper Tooth Assembly for Modular Shredder Rotor Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing comminution devices require different rotor shapes for different shredding tasks, necessitating storage of multiple rotors and complex replacements, which is inefficient and laborious.
Innovation Solution
A ripper tooth arrangement that can be mounted on a bearing axis of a rotor section, allowing for easy conversion between freely oscillating flails and ripper teeth, eliminating the need for multiple rotors by supporting either type as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If different rotor shapes are used for different shredding tasks, then the comminution output is optimized for various feed materials, but storage space increases and rotor replacement becomes complex
Solution Approach 1:
The rotor is divided into modular rotor sections that can be independently exchanged. Each rotor section contains bearing axes that can accommodate different comminution tools (flails or ripper teeth). This segmentation allows quick replacement of only the necessary rotor section rather than the entire rotor, reducing complexity while maintaining optimized performance for different feed materials
Solution Approach 2:
The bearing axes in the rotor sections are designed with universal functionality to accommodate both flails and ripper teeth. The standardized mounting interface allows the same rotor section to support different types of comminution tools depending on the feed material being processed, eliminating the need for multiple specialized rotors and simplifying tool replacement
2Productivity
If multiple rotors are kept on hand for different feed materials, then optimal shredding performance is achieved, but storage space requirements increase
Solution Approach 1:
Instead of storing multiple complete rotors, the system segments the rotor into interchangeable rotor sections. Only the necessary rotor sections with specific comminution tool configurations need to be stored, significantly reducing storage space while maintaining the ability to achieve optimal shredding performance by assembling the appropriate combination of rotor sections
Solution Approach 2:
The system allows changing the comminution tool type (flail or ripper tooth) on the bearing axes by adjusting mounting parameters. This enables a single rotor section to serve multiple functions by simply changing the tool configuration rather than storing multiple specialized rotors, reducing storage requirements while maintaining optimal performance
