Disc Blade Angle Control via Side Load Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural disc blades at increased angles for tillage can enhance tillage but lead to soil compaction, delaying crop emergence and reducing yield due to increased load on the soil's convex side.
Innovation Solution
A disc blade angle control system that adjusts the angle of disc blades based on monitored side loads using sensors and actuators, maintaining a target side load range to balance tillage effectiveness and soil compaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the angle of disc blades is increased to enhance tillage, then the degree of tillage is improved, but the load applied to the soil increases causing compaction
Solution Approach 1:
The patent implements a dynamic angle adjustment mechanism that allows the disc blade angle to change during operation based on real-time side load conditions. The gang support is rotatably coupled to the frame, enabling automatic angular adjustment as the implement moves through the field, transitioning from a static to a dynamic configuration that adapts to varying soil conditions.
Solution Approach 2:
The system incorporates side load sensors that continuously monitor the force applied to the convex side of the disc blades and provide feedback to the control system. This feedback loop enables the controller to adjust the blade angle in response to measured side loads, creating a closed-loop control system that prevents excessive compaction while maintaining effective tillage.
2Manufacturing precision
If the angle of disc blades is increased to break up soil more effectively, then tillage depth is improved, but crop emergence is delayed due to compaction
Solution Approach 1:
The dynamic angle adjustment mechanism allows the system to optimize tillage depth while preventing compaction-induced delays in crop emergence. By continuously adapting the blade angle based on side load feedback, the system maintains effective soil breakdown without creating compaction layers that would hinder seedling emergence.
Solution Approach 2:
The system changes the operational parameters (blade angle) in real-time based on measured side load conditions. The controller adjusts the angle within a predetermined range to optimize the balance between tillage depth achievement and prevention of compaction that would delay crop emergence.
3Manufacturing precision
If the angle of disc blades is increased to enhance soil breakdown, then tillage quality is improved, but yield is reduced due to compaction
Solution Approach 1:
The side load sensor feedback system enables real-time monitoring and adjustment of blade angle to prevent compaction that would reduce crop yield. The controller uses this feedback to maintain optimal tillage quality while avoiding the compaction threshold that leads to yield reduction.
Solution Approach 2:
By dynamically changing the blade angle parameter based on side load measurements, the system optimizes tillage quality to maximize crop yield potential while preventing the compaction that would otherwise occur at higher fixed angles.
