Conditioner Roller Vibration Sensing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mower conditioner rollers in agricultural mechanisms experience vibrations due to improper spacing, leading to inefficiencies in crop conditioning, as they can shift during operation and require frequent adjustments to maintain optimal proximity without contacting each other.
Innovation Solution
A crop conditioning system equipped with an accelerometer to sense vibrations between rollers, allowing for precise adjustment of the roll gap by moving the rollers away from contact, using an arm and linkage system to maintain optimal spacing and prevent vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the rollers are positioned in close proximity to each other for optimal crop conditioning, then the crop conditioning efficiency is improved, but the rollers may contact each other during rotation causing vibrations
Solution Approach 1:
The accelerometer provides real-time feedback on roller contact vibrations, enabling the control system to detect when rollers are contacting and automatically adjust the roll gap to eliminate contact while maintaining optimal conditioning performance
Solution Approach 2:
The system automatically monitors and adjusts roller positioning using the accelerometer and control system, eliminating the need for manual intervention to prevent vibrations while maintaining optimal crop conditioning
2Object-affected harmful factors
If the rollers are adjusted to rotate without contacting each other to prevent vibrations, then vibrations are reduced, but the roll gap increases reducing crop conditioning efficiency
Solution Approach 1:
The accelerometer continuously monitors for roller contact vibrations and provides feedback to the control system, which automatically adjusts the roll gap to the minimum non-contact position, optimizing both vibration reduction and crop conditioning efficiency
Solution Approach 2:
The system dynamically adjusts the roller positioning based on real-time vibration detection, allowing the roll gap to vary automatically to maintain optimal conditioning while preventing contact vibrations
3Manufacturing precision
If manual adjustment of roller position is performed frequently to maintain optimal spacing, then the roll gap can be maintained, but time and operational efficiency are reduced
Solution Approach 1:
The accelerometer-based detection system with automatic control continuously maintains optimal roller spacing without manual intervention, eliminating time loss from frequent adjustments while preserving precise roll gap control
Solution Approach 2:
Real-time vibration feedback from the accelerometer enables automatic detection and correction of roller positioning deviations, maintaining precision without requiring manual measurement and adjustment

AI summary
A conditioner roller vibration sensing mechanism having first and second rotatable conditioner rollers (16, 18) spaced apart in close proximity to each other and between which cut crop can be directed as the rollers rotate during operation. The first roller (16) is shiftable with respect to the second roller (18) for adjusting the spacing between the rollers. The rollers vibrate when the rollers are spaced in such close proximity to each other that they contact each other as they rotate. An arm (28) pivotally mounted to a frame (24) supports the first roller, and the frame (24) supports the second roller. The arm (28) is movable to shift the first roller with respect to the second roller. An accelerometer (38) is operatively coupled to the rollers (16, 18) for sensing the vibration created when the first and second rollers (16, 18) are positioned so close to each other to contact each other.
