Disc Blade Angle Adjustment for Tillage Implements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tillage implements lack the ability to dynamically adjust disc blade angles based on real-time soil conditions, such as residue and soil compaction, which can lead to inefficient tilling operations and reduced agronomic performance.
Innovation Solution
A disc blade angle adjustment system equipped with a controller, sensors, and actuators that adjust the angles of disc blades in real-time based on the amount of residue and soil compaction detected, using sensors to monitor field conditions and adjust the front and rear rows of disc blades accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If disc blade angles are fixed on tillage implements, then the structure is simple and reliable, but the tilling effectiveness is reduced when soil conditions vary
Solution Approach 1:
The patent applies dynamics by making the disc blade angles adjustable rather than fixed. The system dynamically changes the operational parameters (blade angles) based on real-time soil conditions detected by sensors, allowing the tillage implement to adapt to varying residue levels and soil compaction without requiring a completely new design for each condition.
Solution Approach 2:
The patent changes physical parameters (blade angles) in response to changing conditions. The controller adjusts the angular position of disc blade rows based on sensor feedback about residue amount and soil compaction, thereby optimizing tilling effectiveness for different soil conditions through parameter modification rather than structural redesign.
2Productivity
If disc blade angles are adjusted manually, then the system is simple, but the response time to changing soil conditions is slow and productivity is reduced
Solution Approach 1:
The patent implements feedback control by using sensors to continuously monitor soil conditions (residue amount and soil compaction) and automatically adjusting disc blade angles based on this feedback. This closed-loop system eliminates the delay associated with manual observation and adjustment, enabling real-time optimization of tilling operations as soil conditions change.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated electromechanical system. Sensors and controllers substitute for human operators in detecting soil conditions and commanding blade angle adjustments, thereby increasing productivity while introducing a moderate level of automation through electronic control systems.
3Reliability
If disc blade angles are optimized for specific soil conditions, then the tilling effectiveness is improved, but the system cannot adapt to varying conditions across the field
Solution Approach 1:
The feedback mechanism enables the system to maintain reliable tilling effectiveness across varying conditions by continuously monitoring soil parameters and automatically adjusting blade angles. The sensors detect changes in residue and soil compaction, and the controller responds by optimizing blade configuration for current conditions, ensuring consistently effective tilling throughout the field.
Solution Approach 2:
The system maintains tilling effectiveness by dynamically changing blade angle parameters in response to varying soil conditions. Rather than being optimized for a single condition, the system continuously adjusts parameters to match current soil state, thereby maintaining high effectiveness across diverse field conditions.

AI summary
A disc blade angle adjustment system for a tillage implement includes a controller having a memory and a processor. The controller is configured to control a front row actuator to adjust a front angle of a front row of disc blades relative to a lateral axis of the tillage implement based on an amount of residue at a location of the tillage implement. In addition, the controller is configured to control a rear row actuator to adjust a rear angle of a rear row of disc blades relative to the lateral axis of the tillage implement based on a degree of soil compaction at the location of the tillage implement.
