Agricultural Shredder With Segmented Blowing Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shredders for agricultural products, such as bales of straw, are limited to large and expensive agricultural vehicles due to their height, making them unsuitable for smaller vehicles, and drivers struggle to see over the shredding device even in larger vehicles.
Innovation Solution
A shredder design featuring multiple blowing elements with rotatable axes, allowing for a lower and wider configuration without reducing blowing power, enabling use on smaller agricultural vehicles and improving visibility by reducing the height by approximately 30% compared to existing designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a single blowing element is used in the blowing device, then the device complexity is reduced, but the blowing power is insufficient requiring a taller shredder configuration
Solution Approach 1:
The blowing device is segmented into multiple blowing elements (at least two) arranged side by side, each contributing to the total blowing power. This segmentation allows the shredder to achieve sufficient blowing power without increasing height, as the multiple elements work in parallel to move the shredded material through the outlet opening.
Solution Approach 2:
The invention transitions from a single vertical blowing element to multiple blowing elements arranged horizontally side by side. This dimensional change from vertical stacking to horizontal arrangement reduces the required height while maintaining or increasing the total blowing power, directly resolving the contradiction between power and height.
2Adaptability or versatility
If the shredder height is reduced for use on smaller vehicles, then the adaptability to smaller agricultural vehicles improves, but the blowing power may be compromised
Solution Approach 1:
The blowing device is divided into multiple blowing elements that can be arranged horizontally, allowing the overall shredder height to be reduced for compatibility with smaller vehicles while the combined power of multiple elements maintains sufficient blowing capability.
Solution Approach 2:
By arranging blowing elements side by side in a horizontal configuration rather than vertically stacked, the invention reduces height for vehicle adaptability while preserving blowing power through the additive effect of multiple elements operating in parallel.
3Illumination intensity
If the shredder height is reduced, then the visibility for drivers on smaller vehicles improves, but the blowing power may be reduced
Solution Approach 1:
The invention changes the arrangement from vertical to horizontal, reducing height to improve driver visibility while maintaining blowing power through the use of multiple blowing elements arranged side by side that collectively provide sufficient airflow to move shredded material through the outlet.
4Power
If multiple blowing elements are added to maintain blowing power, then the blowing power is improved, but the device complexity increases
Solution Approach 1:
The blowing device is segmented into multiple identical or similar blowing elements arranged side by side. This segmentation approach maintains relative simplicity by using repeated modular units rather than a single complex element, allowing the system to scale power through replication rather than through increasing the complexity of individual components.
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
The shredder can be effectively used by smaller, less expensive agricultural vehicles, enhancing operational efficiency and visibility by maintaining blowing power while reducing the overall height, thus accommodating a broader range of vehicle types.
Implementation Method 1
a blowing device for blowing the shredded agricultural products from the shredding device toward and through the outlet opening, wherein the blowing device comprises a first blowing element, wherein the first blowing element is rotatably arranged about a first blowing rotational axis, wherein rotating the first blowing element about the first blowing rotational axis causes the shredded agricultural products to be blown from the shredding device toward and through the outlet opening
