Manure Spreader Vertical Beater with Reverse Flighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercially available manure spreaders with vertical beaters often expel manure unpredictably, posing safety hazards due to debris hitting the spreader or towing vehicle, and result in inconsistent spread patterns, especially with solid manures or debris like rocks.
Innovation Solution
A manure spreader design featuring a vertical beater assembly with a first helical flighting section spiraling upward and a second helical section spiraling downward, which together propel manure in opposite directions to create a uniform spread pattern while minimizing debris return towards the spreader or towing vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional vertical beater design is used, then manure can be expelled in a controlled fashion with consistent distribution pattern, but manure and debris are expelled unpredictably back toward the spreader or towing vehicle causing safety hazards
Solution Approach 1:
The vertical beater is divided into two distinct flighting sections: a first flighting section that expels manure upward and outward, and a second flighting section that expels manure downward and outward. This segmentation allows each section to control the direction of manure expulsion, preventing debris from returning to the spreader while maintaining consistent distribution pattern.
Solution Approach 2:
Different portions of the vertical beater are given different functional qualities through the two flighting sections. The first flighting section is optimized for upward expulsion to distribute manure overhead, while the second flighting section is optimized for downward expulsion to prevent debris return. This local differentiation of function resolves the contradiction between consistent spread pattern and debris containment.
2Adaptability or versatility
If traditional vertical beater design is used, then manure spreader can handle various manure compositions, but spread pattern becomes unpredictable and inconsistent especially with solid manures or debris
Solution Approach 1:
The beater assembly is segmented into two flighting sections with different expulsion directions. The first flighting handles manure expulsion upward for distribution, while the second flighting handles downward expulsion to control debris. This segmentation provides precise control over spread pattern consistency across different manure types including solids and debris.
Solution Approach 2:
The invention changes the geometric parameters of the flighting sections, specifically their helical configurations and angles, to optimize manure expulsion for different compositions. The first flighting uses parameters suitable for upward expulsion while the second flighting uses parameters for downward expulsion, enabling consistent spread patterns across various manure types.
3Object-affected harmful factors
If shields or guards are added to prevent debris from reaching towing vehicle and operator, then safety is improved, but device complexity increases
Solution Approach 1:
The harmful effect of debris return is eliminated at the source by modifying the beater assembly itself. By extracting and redesigning the flighting sections to include a second section that expels manure downward, the invention removes the need for additional shields or guards, thereby preventing debris from reaching the towing vehicle and operator without increasing device complexity.
Solution Approach 2:
The invention converts the potential harm of upward-expelled manure into a benefit by using the first flighting to expel manure upward for distribution, then using the second flighting to catch and redirect this manure downward. This transforms what could be a harmful upward trajectory into a controlled distribution pattern that prevents debris return without requiring additional protective structures.

AI summary
A manure spreader includes a box for containing manure. The manure spreader box includes a bottom wall, a front wall, two side walls, and a manure discharge opening. The manure spreader also includes a wheeled frame supporting the box, and a vertical beater assembly for engaging and expelling manure. The vertical beater assembly includes a first vertical beater rotatable about a first axis and includes a shaft having a first flighting forming a left-handed helix, and a second flighting forming a right-handed helix. The manure spreader also includes a manure transfer mechanism for moving manure contained in the box to the manure discharge opening for engagement with the vertical beater assembly.
