Corn Header Airborne Particle Sensor for Kernel Loss Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During crop harvesting, especially with corn headers, a significant portion of kernels is lost due to 'butt-shelling' – kernels being dislodged into the air as they impact with header components, leading to reduced yield and efficiency.
Innovation Solution
An airborne particle sensor system is integrated into the header, comprising sensors and a controller that detect airborne particles and adjust operating parameters such as deck plate gap size and stalk roller speed to minimize kernel loss by optimizing the harvesting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If kernels are separated from stalks using impact with header components, then harvesting efficiency is improved, but kernel loss increases due to butt-shelling
Solution Approach 1:
The system dynamically adjusts operating parameters (deck plate gap size, stalk roller speed) in real-time based on sensor feedback about airborne kernel particles, transforming a static harvesting process into a dynamic one that adapts to minimize kernel loss while maintaining separation efficiency
Solution Approach 2:
The system uses sensors to detect airborne kernel particles and feeds this information back to the controller, which then adjusts operating parameters to reduce kernel loss, creating a closed-loop control system that continuously optimizes the harvesting process
2Measurement precision
If sensor systems are added to detect airborne particles, then kernel loss detection is improved, but device complexity increases
Solution Approach 1:
The system replaces complex mechanical measurement methods with optical/electronic sensors that detect airborne kernel particles, simplifying the measurement process while improving detection precision and enabling real-time monitoring
Solution Approach 2:
The sensor system automatically monitors and detects kernel loss without requiring manual intervention, and the controller autonomously adjusts parameters based on sensor data, reducing the need for operator involvement and simplifying operation

AI summary
A header for an agricultural system includes a plurality of row units distributed across a width of the header, one or more sensors coupled to the header and configured to generate respective signals indicative of a plurality of objects in an area proximate the header, and a controller comprising a memory and a processor. The one or more sensors are oriented such that a field of view of the one or more sensors comprises an area forward of the header relative to a direction of travel of the header and above the header relative to a soil surface, and the controller is configured to receive the respective signals from the one or more sensors coupled to the header and process the respective signals to determine an amount of butt-shelling occurring on the header.
