Row-Crop Cultivator Steering Control for Precise Row Following
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural attachment systems for processing row crops rely on manual steering interventions, which are strenuous and limit working speed, and existing solutions are either complex or provide only slight improvements in processing results.
Innovation Solution
An agricultural attachment equipped with a signal generating device that detects plant row positions and courses, generating steering commands to automatically adjust the attachment's position and orientation, allowing the machine to follow rows accurately and reduce the need for manual steering, thereby increasing precision and reducing operator effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual steering intervention is used to correct implement position and alignment, then the implement can be adjusted to follow plant rows, but the operator workload increases and working speed is limited
Solution Approach 1:
The system enables self-service operation by automatically detecting plant row positions and generating steering commands without requiring manual intervention. The row detection device continuously monitors row positions and the control unit automatically adjusts steering, allowing the implement to self-correct its position and alignment while following rows at higher speeds
Solution Approach 2:
The system implements continuous feedback by using the row detection device to monitor actual row positions and comparing them with desired positioning. The control unit receives real-time data about row deviations and dynamically generates corrective steering commands, creating a closed-loop control system that maintains precise alignment automatically
2Measurement precision
If a sliding frame is used to adjust implement position relative to drive vehicle, then alignment precision is improved, but device complexity and cost increase
Solution Approach 1:
The system replaces complex mechanical adjustment mechanisms like sliding frames with an electronic control system. Instead of mechanically shifting the implement through a sliding frame, the control unit generates steering commands that guide the drive vehicle to follow detected row positions, achieving alignment precision through electronic steering control rather than mechanical displacement
Solution Approach 2:
The invention extracts the essential function of alignment from complex mechanical structures. By removing the sliding frame and its associated mechanical complexity, the system retains only the critical function of position adjustment through electronic steering commands generated based on row detection data
3Measurement precision
If manual steering correction is performed on the tractor, then the direction of travel changes to follow rows, but the entire machine combination must be repositioned which reduces working efficiency
Solution Approach 1:
The system ensures continuous operation at optimal working speeds by automatically making steering adjustments without requiring the machine combination to slow down or stop. The row detection device and control unit continuously monitor and correct positioning in real-time, allowing the tractor to maintain steady forward motion while precisely following row paths
