Agricultural Tool Plugging Detection via Residue Differential
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural implement ground-engaging tools often become plugged with debris, reducing their effectiveness and leading to premature mechanical failure due to trapped dirt or crop residue, which existing technologies fail to detect and address efficiently.
Innovation Solution
A system and method that utilize sensors to capture data on residue coverage before and after the ground-engaging tools operate, analyzing the differential to identify when tools are plugged and allowing for corrective action to be taken, either manually or automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ground-engaging tools operate continuously in tillage operations, then productivity is improved, but tools become plugged with debris reducing effectiveness and increasing risk of mechanical failure
Solution Approach 1:
The system continuously monitors residue coverage behind the ground-engaging tools using sensors and compares it to expected values to detect plugging conditions. This feedback mechanism allows real-time identification of tool inefficiency, enabling operators to take corrective action before mechanical failure occurs, thus maintaining both productivity and reliability.
Solution Approach 2:
The patent replaces direct mechanical monitoring of tool condition with an optical sensing system that measures residue coverage. Instead of mechanically inspecting the tools, the system uses optical sensors to detect the presence of plugs by measuring changes in residue distribution patterns, providing a non-contact method for condition monitoring.
2Manufacturing precision
If ground-engaging tools penetrate soil to maintain depth, then tillage effectiveness is improved, but tools become more susceptible to plugging with dirt and crop residue
Solution Approach 1:
The system provides continuous feedback on tool performance by monitoring residue coverage patterns. When plugging is detected through deviations from expected residue distribution, the system can trigger alerts or automatic adjustments to prevent further debris accumulation, maintaining both penetration depth control and resistance to harmful factors.
Solution Approach 2:
By continuously monitoring residue coverage and detecting early signs of plugging before they become severe, the system enables preliminary corrective actions. This allows operators to address debris accumulation issues before they compromise tool effectiveness or lead to mechanical failure, maintaining optimal tool performance throughout the tillage operation.
3Device complexity
If no monitoring system is used, then device complexity is reduced, but plugging conditions go undetected leading to premature tool failure
Solution Approach 1:
The patent replaces complex mechanical monitoring systems with a simpler optical sensing approach. Instead of mechanically inspecting tools or using complex sensor arrays, the system uses optical sensors to measure residue coverage patterns, providing a straightforward method for detecting plugging conditions with minimal added complexity while significantly improving reliability.
Solution Approach 2:
The system incorporates feedback through optical sensing to continuously monitor tool performance. By comparing actual residue coverage measurements against expected values, the system can detect plugging conditions and provide alerts, maintaining tool reliability without requiring complex mechanical monitoring infrastructure.

AI summary
A system for detecting plugging of ground-engaging tools of agricultural implements includes an aft sensor(s) configured to capture data indicative of a post-worked residue coverage of a portion of a field aft of a ground-engaging tool(s). The system includes a controller configured to monitor the data received from the aft sensor(s) and determine the post-worked residue coverage for the portion of the field. The controller is configured to identify when the ground-engaging tool(s) is experiencing a plugged condition based at least in part on the determined post-worked residue coverage for the field.
