Resilient Impact Pad for Tree Stump Grinding Teeth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tree stump grinding machines face issues with grinding teeth breaking or wearing out due to impact forces, leading to vibration, wheel imbalance, and premature wear, as well as damage to the wheel surface and corrosion from moisture ingress.
Innovation Solution
The use of grinding teeth with a mounting base featuring cleats that fit into corresponding bores on the wheel, combined with a resilient impact pad between the tooth and the wheel to absorb impact forces and prevent moisture ingress, ensuring secure fastening and extended wheel life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If grinding teeth are fastened directly to the wheel using bolts, then the grinding teeth can be securely attached, but the impact forces can cause the bolts to fail and the grinding teeth to shear away
Solution Approach 1:
A resilient impact pad is introduced as an intermediary component between the grinding tooth mounting base and the wheel surface. This pad absorbs impact forces transmitted through the bolts, preventing bolt failure while maintaining secure attachment of the grinding teeth to the wheel
2Device complexity
If grinding teeth are fastened directly to the wheel, then the attachment is simple, but the impact forces can deform the holes bored into the wheel
Solution Approach 1:
The resilient impact pad serves as a mediator that absorbs impact forces before they reach the wheel surface, preventing deformation of the bored holes and maintaining their precise orientation for proper grinding tooth alignment
3Ease of manufacture
If the wheel surface is in direct contact with the mounting base, then the attachment is straightforward, but moisture can wick between the tooth and wheel causing corrosion
Solution Approach 1:
The resilient impact pad acts as a moisture barrier between the mounting base and the wheel surface, preventing moisture wicking and corrosion while maintaining the simplicity of the assembly process
4Loss of time
If grinding teeth are replaced without a protective layer, then the replacement process is quick, but the wheel surface can become damaged
Solution Approach 1:
The resilient impact pad is pre-installed on the wheel surface before grinding teeth are mounted, providing continuous protection against impact damage during operation and simplifying the replacement process by preventing surface degradation over time
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 configuration enhances the durability of grinding teeth and wheel surfaces by distributing impact forces, preventing damage and corrosion, and simplifying the replacement process while maintaining wheel balance.
Implementation Method 1
A resilient impact pad is positioned between the mounting base of the grinding tooth and the wheel. The resilient impact pad protects the surface of the wheel from impact forces applied to the grinding tooth.
Implementation Method 2
A resilient impact pad is positioned between the mounting base of the grinding tooth and the wheel. The resilient impact pad protects the surface of the wheel from impact forces applied to the grinding tooth.
