Crop Deflector for Harvesting Head Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional harvesting heads often experience issues with crop material departing from the desired flow path, leading to inefficiencies and potential loss during the harvesting process in agricultural combines.
Innovation Solution
The implementation of a crop deflector mechanism, which includes an elongate reciprocating knife, a conveyor system, a drum conveyor with elongate fingers, and a crop deflector affixed to the frame, positioned to interface with the drum and fingers to deflect crop material rearward along the desired flow path, preventing ejection or forward displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a conventional harvesting head is used without a crop deflector, then the structure is simpler and easier to manufacture, but crop material departs from the desired flow path causing losses and inefficiencies
Solution Approach 1:
The crop deflector is divided into multiple segments or sections that can be independently positioned and adjusted. Each segment can be tailored to deflect crop material in specific zones, allowing precise control over crop flow paths while maintaining manufacturing simplicity through modular construction
Solution Approach 2:
The crop deflector acts as an intermediary component positioned between the drum conveyor and the crop flow path. It mediates the interaction between the mechanical conveying system and the crop material, redirecting crop flow without requiring fundamental changes to the existing harvesting head structure
2Reliability
If a crop deflector is added to interface with the drum conveyor, then crop material flow path control is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The crop deflector is designed to perform multiple functions simultaneously: it deflects crop material, protects the drum conveyor from excessive crop contact, and can be adjusted to accommodate different crop types and harvesting conditions. This multi-functionality justifies the added complexity by providing reliable crop flow control across various operating scenarios
Solution Approach 2:
The crop deflector incorporates adjustable and movable components that allow dynamic adaptation to different harvesting conditions. The ability to adjust the deflector position and angle enables reliable crop flow path control while simplifying manufacturing through standardized, reconfigurable components rather than custom-designed rigid structures

AI summary
Harvesting machines and agricultural harvesting heads for harvesting machines are disclosed herein. A harvesting machine includes a frame, an elongate reciprocating knife, a conveyor system, a drum conveyor, and a crop deflector. The elongate reciprocating knife is coupled to a forward edge of the frame and configured to cut crop material adjacent to the ground. The conveyor system is supported by the frame and configured to carry cut crop material toward a central portion of the frame and rearward therefrom. The drum conveyor is located directly behind at least a portion of the conveyor system, and the drum conveyor includes an elongate cylindrical drum supported for rotation on the frame about a drum axis and a plurality of elongate fingers that at least partially extend through an outer wall of the cylindrical drum.
