Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distribution devices, such as centrifuging spreaders, often destroy or reduce the size of granulate during acceleration due to the trapping mechanism, impairing the effectiveness of the output and lacking the ability to vary the discharge angle.
Innovation Solution
A distribution device that utilizes a rotating ejection wheel with a groove and belt system, generating sufficient centrifugal forces to keep granulate in place without destruction, allowing for adjustable discharge angles by varying the ejection wheel's rotation speed, belt separation point, and ejection wheel size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If granulate is trapped between two rotating rollers for acceleration, then the granulate can be accelerated effectively, but the granulate is destroyed or reduced in size
Solution Approach 1:
A belt is introduced as an intermediary element between the ejection wheel and the granulate. The belt receives granulate from the hopper, conveys it to the ejection wheel, and releases it at the discharge point. This intermediary mechanism allows acceleration without direct trapping between rollers, preserving granulate integrity while achieving effective acceleration through centrifugal force.
2Adaptability or versatility
If a fixed discharge angle mechanism is used, then the device structure is simple, but the discharge angle cannot be varied
Solution Approach 1:
The discharge angle is made variable by allowing the belt to be positioned at different angles relative to the ejection wheel. The belt can be adjusted to discharge granulate at different angles (e.g., 45°, 90°, 135°) by changing its position on the ejection wheel, providing adaptability without requiring complex mechanical discharge mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents granulate destruction during acceleration, enables precise control over discharge angles and distances, and ensures even distribution, particularly beneficial for agricultural applications like fertiliser spreading.
Implementation Method 1
Through the rotation of the ejection wheel such large centrifugal forces are created which are sufficient to press the granulate onto the belt strongly enough so that the granulate, cannot fall out of the intermediate space during the rotation of the ejection wheel
Implementation Method 2
the granulate during its acceleration, caused in particular predominantly, preferentially exclusively through centrifugal force
