Agricultural Belt Conveyor With Pivoting Foreign-Body Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural machines lack effective systems for reliably detecting and ejecting foreign bodies during the conveyance of harvested crops, leading to potential damage and material waste.
Innovation Solution
A conveying device with a belt conveyor system that includes a pivoting ejection section and a cutting device to divert and separate foreign bodies from the material flow, utilizing sensors for detection and controlled pivoting mechanisms to ensure precise ejection and minimal material loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foreign bodies are detected and ejected from the material flow, then detection reliability is improved, but material waste increases due to ejection of foreign bodies and surrounding material
Solution Approach 1:
The material flow is divided into individual material pieces or small groups rather than ejecting large portions. The ejection mechanism targets and removes only the specific foreign body or the minimal surrounding material attached to it, segmenting the ejection action from the bulk material flow. This segmentation approach maintains high detection reliability while minimizing material waste by precisely isolating and removing only the problematic elements.
2Stability of the object's composition
If a stationary conveyor system is used, then system stability is improved, but adaptability to different ejection scenarios deteriorates
Solution Approach 1:
The conveyor system incorporates dynamically adjustable components, specifically the ejection mechanism that can be activated selectively based on foreign body detection. The system transitions from a purely stationary configuration to one with controlled dynamic elements - the ejection apparatus remains integrated with the stable conveyor structure but can be actuated to eject material at specific locations and angles, providing adaptability while maintaining overall system stability.
3Reliability
If material is ejected to remove foreign bodies, then foreign body removal effectiveness is improved, but ejection precision deteriorates leading to excessive material loss
Solution Approach 1:
The ejection mechanism is designed with localized action characteristics, targeting specific regions of the material flow where foreign bodies are detected. The ejection force and angle are optimized for local material removal rather than broad-area ejection. This local quality approach concentrates the ejection effect precisely where needed, improving both foreign body removal effectiveness and ejection precision by avoiding unnecessary disturbance of surrounding material.
