Roll Conditioner Gap Control for Consistent Crop Conditioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crop conditioning systems in agricultural vehicles rely on manual trial-and-error adjustments of parameters like roll gap and pressure, leading to inconsistent conditioning results due to varying crop yield and density across a field.
Innovation Solution
Implementing a crop conditioning system with sensors and controllers that monitor and automatically adjust roll gap and pressure based on crop quantity flow rate and density, using algorithms to optimize conditioning levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual trial-and-error adjustments are used for roll gap and pressure, then the system complexity remains low, but the manufacturing precision and reliability of crop conditioning deteriorate due to inconsistent results
Solution Approach 1:
The patent implements sensors (load cells, displacement sensors) that continuously monitor the force applied by rollers and gap dimensions, feeding this data back to a controller. The controller automatically adjusts roller position and pressure based on this feedback, replacing manual trial-and-error with closed-loop control. This resolves the contradiction by achieving consistent crop conditioning through automated feedback mechanisms while managing system complexity through integrated control electronics.
Solution Approach 2:
The conditioning system performs self-adjustment of roll gap and pressure based on sensor inputs and control algorithms. The system monitors its own performance parameters and automatically corrects deviations without operator intervention, enabling the equipment to service itself. This eliminates manual adjustments while maintaining precision, resolving the contradiction between automation and complexity.
2Adaptability or versatility
If fixed roll gap and pressure settings are used, then the ease of operation is high, but the adaptability to varying crop yield and density deteriorates
Solution Approach 1:
The patent transitions from static, fixed roll gap and pressure settings to dynamic, variable settings that automatically adjust based on real-time sensor data. The system continuously modifies roller position and applied force in response to changing crop density and flow rate conditions. This dynamic adaptation capability resolves the contradiction by enabling the system to handle varying crop conditions while the automated control maintains operational simplicity for the user.
Solution Approach 2:
The system automatically changes critical parameters (roll gap distance, applied pressure force) based on detected crop conditions. Sensors monitor crop density and flow rate, and the controller adjusts these parameters in real-time to optimize conditioning for each local condition. This parameter variability resolves the contradiction between adaptability and ease of operation, as the system handles complexity internally while remaining simple to operate.
3Productivity
If automated sensor-based monitoring is implemented, then the productivity and conditioning consistency improve, but the device complexity and initial cost increase
Solution Approach 1:
The patent integrates multiple functions into a single automated control system: sensors monitor both gap dimensions and applied force, the controller processes this data, and the system simultaneously adjusts roller position and pressure. This multi-functional integration improves productivity by handling multiple parameters automatically while managing complexity through consolidated control architecture, resolving the contradiction between enhanced productivity and increased system complexity.

AI summary
A crop conditioning system for an agricultural vehicle includes a crop conditioning arrangement having a frame, a first roller rotatably mounted to the frame, a second roller movably and rotatably mounted to the frame. A space between the first roller and second roller defines a gap for receiving crop material. A biasing member is operatively coupled to the second roller and biases the second roller toward the first roller. A first sensor is configured to detect the gap. A controller receives input data from the first sensor and outputs control signals to control the crop conditioning arrangement. The controller includes a processor configured to determine a status of the crop conditioning arrangement based on the input data. The determined status is indicative of a level of crop conditioning. The processor generates adjustment data indicative of an adjustment to the second roller in response to the determined status.
