Funnel Chute Projection for Granular Spreading Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural spreading machines face challenges in maintaining a constant spreading pattern due to varying delivery quantities and external influences, such as wind and material properties, which affect the lateral distribution and accuracy of granular materials like seed and fertilizer.
Innovation Solution
The design incorporates a transfer device with a second side wall projection that directs granular material over a first side wall, allowing for adjustable and bundled flow, along with multiple transfer devices and a rotatable funnel tip for precise control over the application point, enabling improved spreading accuracy and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid transfer device structure is used, then the structural stability is improved, but the adjustability of the drop point deteriorates
Solution Approach 1:
The transfer device incorporates a movable side wall that can be adjusted in its position to change the drop point location. This dynamic element allows the rigid structure to adapt to different spreading requirements by modifying the discharge position, thereby resolving the contradiction between structural stability and adjustability.
2Productivity
If the delivery rate of the dosing device is increased, then the productivity is improved, but the application accuracy deteriorates
Solution Approach 1:
The transfer device divides the granular material flow into separate bundled flows through its structured design with side walls and flow guidance elements. This segmentation allows each flow to be controlled independently, maintaining application accuracy even when the overall delivery rate is increased, thus resolving the contradiction between productivity and precision.
3Quantity of substance
If the dosing device width is increased, then the quantity of substance conveyed is improved, but the interference with the flow opening deteriorates
Solution Approach 1:
The transfer device is designed with a vertical projection from the second side wall that extends into the flow path. This three-dimensional configuration allows the dosing device to have increased width for higher conveyance capacity while the vertical projection manages the material flow to prevent interference with the flow opening, resolving the contradiction between quantity capacity and flow interference.
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
This design ensures a consistent spreading pattern across varying delivery quantities and external conditions, enhancing the precision and efficiency of granular material distribution, particularly in agricultural applications.
Implementation Method 1
the granular material, preferably in the form of at least one bundled flow, is fed to the flow opening almost exclusively via the at least one first side wall of the transfer device. The material transferred from the dosing device into the transfer device, which material is located vertically above the flow opening, can be deflected onto the at least one first side wall by means of the projection.
