Agricultural seeding implements face issues with uneven distribution of particulate materials due to undesirable profiles in storage tanks, leading to reduced crop yield and efficiency, caused by factors like friction, clumping, and inactive metering system portions.
Innovation Solution
A particulate material sensing and agitation control system that includes sensors and a controller to monitor the profile and adjust it by operating an agitating system in various modes, ensuring a consistent flow and distribution of materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the storage tank is filled with particulate material, then the storage capacity is improved, but an undesirable profile is created leading to uneven flow
Solution Approach 1:
The agitating system operates in advance to distribute particulate material uniformly throughout the storage tank before metering begins, preventing undesirable profile formation and ensuring even flow to the metering system throughout operation
Solution Approach 2:
The agitating system operates periodically or continuously at controlled intervals to maintain uniform material distribution and prevent clumping, friction buildup, and profile degradation that would otherwise occur during storage
2Stability of the object's composition
If the agitating system operates continuously, then the material distribution is improved, but the energy consumption increases
Solution Approach 1:
The controller operates the agitating system in alternating active and inactive periods, activating it when sensors detect material accumulation or profile degradation, and deactivating it when uniform distribution is maintained, thereby reducing overall energy consumption while preserving material distribution uniformity
Solution Approach 2:
Sensors monitor the material profile and flow conditions in real-time, providing feedback to the controller which adjusts agitating system operation accordingly - increasing agitation when distribution degrades and reducing or stopping agitation when uniformity is maintained, optimizing energy usage
3Ease of operation
If friction between particulate material and storage tank is increased, then the material flow control is improved, but the distribution uniformity worsens
Solution Approach 1:
The agitating system applies mechanical vibration or agitation to the particulate material, reducing friction between particles and the tank wall, preventing clumping, and promoting uniform flow to the metering system while maintaining controllable flow rates
