Rotatable Flow Controller for Air Seeder Metering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air seeding systems require complex diverter valves and linkages for selective routing of particulate materials, making them mechanically complex and difficult to quickly stop or redirect material flow.
Innovation Solution
A metering assembly with a rotatable flow controller, such as an auger or roller, that selectively routes particulate material to either of two loading zones, allowing for efficient metering and distribution through air stream passages connected to distribution lines, and the ability to prevent material flow by stopping the rotatable member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex diverter valves and linkages are used for selective routing of particulate materials, then the ability to route material to different distribution lines is improved, but the mechanical complexity of the system increases
Solution Approach 1:
The patent removes the complex diverter valves and linkages from the system entirely. Instead, it uses a single auger that can be selectively engaged or disengaged from different product tanks, extracting the routing function from a complex mechanical valve system to a simpler engagement/disengagement mechanism.
Solution Approach 2:
The auger serves multiple functions: it can meter material from different product tanks, route material to different distribution lines, and can be selectively engaged or disengaged. This single multi-functional component replaces what previously required separate valves and linkages for each routing decision.
2Adaptability or versatility
If complex diverter valves and linkages are used for selective routing, then material can be directed to different distribution lines, but the system becomes difficult to operate and adjust quickly
Solution Approach 1:
The patent extracts the routing control from complex valve linkages and places it directly on the auger engagement mechanism. This allows the operator to control material flow by simply engaging or disengaging the auger, which is a much simpler and faster operation than manipulating multiple valves and linkages.
Solution Approach 2:
The auger system is designed so that the same component that meters the material also controls its routing. By engaging or disengaging the auger from different product tanks, the system automatically routes material without requiring separate control mechanisms, making the system easier to operate.
3Device complexity
If a rotatable member such as an auger is used for metering and routing, then the mechanical complexity is reduced, but the ability to quickly stop material flow must be maintained
Solution Approach 1:
The patent extracts the flow control function from complex valve mechanisms and places it directly on the auger engagement mechanism. When the auger is disengaged from a product tank, material flow stops immediately, providing quick flow stoppage without requiring additional valves or complex control mechanisms.
Solution Approach 2:
The engagement mechanism acts as an intermediary between the auger and the product tanks. By controlling whether the auger is engaged or disengaged, the system can quickly start or stop material flow without requiring the auger itself to have complex flow control features, maintaining mechanical simplicity while achieving fast response.
