Pneumatic Agricultural Material Ejection Without Crushing or Sticking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural material ejecting devices require high-speed rotor blades to forcefully eject granular material, leading to potential crushing and sticking issues, which can cause operation failures.
Innovation Solution
An agricultural material ejecting device uses a gas compressor and blower to forcefully eject granular material using compressed gas, eliminating the need for high-speed rotor blades and preventing material crushing or sticking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If high-speed rotor blades are used to forcefully eject agricultural material, then ejection force is improved, but agricultural material may be crushed or stuck causing operation failure
Solution Approach 1:
The patent replaces the mechanical rotor blade ejection system with a pneumatic system. Compressed gas is introduced into the storage chamber to fluidize and propel the agricultural material through a nozzle, eliminating direct mechanical contact between high-speed rotating blades and the material, thus preventing crushing and sticking while maintaining reliable operation
Solution Approach 2:
The patent employs compressed gas (pneumatics) to eject the agricultural material. The gas compressor generates compressed gas that is directed into the storage chamber, creating a pneumatic flow that propels the material outward through the nozzle. This pneumatic mechanism provides controlled ejection force without the harmful effects of mechanical blade impact
2Productivity
If rotor rotates at high speed to eject agricultural material, then ejection capability is improved, but agricultural material may become stuck between blade tip and guide surface
Solution Approach 1:
The patent eliminates the high-speed rotating mechanical blade system and replaces it with a stationary pneumatic ejection system. Compressed gas flows through the storage chamber and propels material through a nozzle, removing the rotating components that create sticking zones between blade tips and guide surfaces, ensuring continuous operation without material entanglement
Solution Approach 2:
The patent extracts and removes the rotor blade mechanism from the ejection system. By taking out the high-speed rotating blades that cause material to become stuck, the system achieves reliable continuous operation while maintaining ejection capability through the pneumatic propulsion method
3Force
If blades forcefully eject agricultural material downward, then ejection effectiveness is improved, but agricultural material does not necessarily enter upstream space in rotation direction
Solution Approach 1:
The patent uses pneumatic flow to eject material in a controlled trajectory. The compressed gas enters the storage chamber and propels material through a directed nozzle, allowing precise control of material flow direction and position without the chaotic motion caused by high-speed rotating blades, improving both ejection effectiveness and operational ease
