Residue Deflector Assembly for Clear Crop Loss Camera View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The effectiveness of crop loss monitoring systems in agricultural harvesters is reduced due to stalks and leaves blocking the camera's field of view, leading to incomplete detection of crop material behind the harvester.
Innovation Solution
A residue deflection assembly is positioned rearward of the row units in the harvester, featuring a residue deflector that directs stalks and leaves away from the camera's field of view, allowing crop material to be monitored effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera is positioned to monitor crop material behind the harvester, then crop loss detection capability is improved, but the field of view is blocked by stalks and leaves
Solution Approach 1:
The harmful stalks and leaves are extracted from the camera's field of view by the deflector, separating the monitoring function from the residue discharge path. The deflector creates a dedicated residue channel that removes obstructions while preserving the camera's ability to detect crop material.
Solution Approach 2:
The deflector acts as an intermediary element between the residue discharge area and the camera. It intercepts and redirects stalks and leaves away from the field of view, mediating the conflict between residue management and optical monitoring without requiring changes to either the camera or harvestor operation.
2Ease of operation
If residue is allowed to fall naturally behind the harvester, then harvesting operation simplicity is maintained, but camera monitoring effectiveness is reduced
Solution Approach 1:
The deflector serves as a simple intermediary component that passively redirects residue without complicating the harvesting operation. It integrates into the existing harvestor structure and works automatically with the natural residue discharge flow, maintaining operational simplicity while improving monitoring reliability.
Solution Approach 2:
The deflector applies a localized modification to the residue discharge path rather than changing the entire harvesting system. By focusing the intervention only where needed (at the rear of the harvestor where residue falls), it maintains the simplicity of the overall operation while locally solving the monitoring obstruction problem.

AI summary
A residue deflection assembly for a crop loss monitoring system includes a residue deflector configured to be positioned rearward of a row unit of a header of an agricultural harvester relative to a direction of travel of the agricultural harvester. The residue deflector is configured to direct residue away from a field of view of a camera of the crop loss monitoring system and to enable crop material to be present within the field of view of the camera.
