Vibratory Ripper Guide Roller Cushioning for Longer Service Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vibratory rippers face issues with vibration absorption and durability, leading to potential damage and reduced lifespan, particularly in the guide roller mechanism, which also complicates maintenance.
Innovation Solution
The design incorporates a guide roller with a fixing plate, a shock-absorbing member, and a support structure to stabilize and absorb vibrations, including a coil and bolt system to distribute shock, and stoppers to restrict movement, enhancing durability and maintenance accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a guide roller is used to guide vertical movement of the vibratory body, then the vibratory body is guided to move vertically, but shock is transmitted to the guide roller causing damage and reduced lifespan
Solution Approach 1:
The patent applies beforehand cushioning by installing a shock absorbing member between the guide roller and the external body before shock transmission occurs. This shock absorbing member preemptively cushions the shock that would otherwise be transmitted to the guide roller, preventing damage and extending the guide roller's lifespan while maintaining guiding stability.
2Stability of the object's composition
If the guide roller is firmly fixed to the external body, then the guide roller is securely positioned, but maintenance of the guide roller becomes difficult
Solution Approach 1:
The patent applies segmentation by dividing the fixing structure into separable components - the guide roller is fixed to the fixing plate through a fixing member that allows for easy assembly and disassembly. This segmentation enables the guide roller to be firmly fixed during operation while allowing straightforward maintenance by simply removing the fixing member, without requiring complex disassembly procedures.
3Ease of operation
If the vibratory body is allowed to move freely vertically, then the vibratory operation is smooth, but the moving distance becomes uncontrolled causing potential damage
Solution Approach 1:
The patent applies preliminary anti-action by installing stoppers that preemptively prevent the vibratory body from moving beyond the predetermined safe range. The stoppers are positioned in advance to counteract any excessive movement tendency, ensuring that while the vibratory body can move freely within the safe range for smooth operation, it cannot exceed the controlled limits that would cause damage.
