Reversible Cutting Edge for Agricultural Mixer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural mixer cutting edges for ruminant feed preparation are prone to damage and wear, leading to costly and inconvenient replacement issues, especially when working in various locations where spare parts may be misplaced or unavailable.
Innovation Solution
A reversible cutting edge system where each cutting edge plate has two ranks of teeth that can be rotated to expose fresh teeth for continued use, with a mounting system allowing for adjustable orientation and self-sharpening capabilities, reducing the need for frequent replacements and simplifying field repairs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If cutting edges are made replaceable, then serviceability is improved, but device complexity increases
Solution Approach 1:
The cutting edge is divided into two separate parts: a holder plate that remains attached to the auger and a cutting edge blade that can be removed and replaced. This segmentation allows the cutting edge blade to be easily replaced when worn or damaged, while the holder plate remains fixed, thus improving serviceability without significantly increasing overall device complexity.
Solution Approach 2:
The mounting system uses bolts that allow the cutting edge blade to be dynamically adjusted and repositioned on the holder plate. This dynamic mounting mechanism enables easy replacement and reconfiguration of the cutting edge blade, improving ease of repair while maintaining a relatively simple device structure.
2Reliability
If spare cutting edges are kept on hand, then reliability is improved, but loss of substance increases
Solution Approach 1:
The cutting edge blade is designed to be reusable and repositionable. When one set of cutting teeth becomes worn, the blade can be removed from the holder plate and reattached in a reversed or repositioned orientation to expose fresh cutting teeth. This allows the same physical blade to be used multiple times, reducing the need to discard and replace blades frequently, thus reducing material consumption while maintaining reliability.
3Duration of action of moving object
If cutting edges are made reversible, then duration of action is extended, but device complexity increases
Solution Approach 1:
The holder plate includes multiple mounting positions and adjustment mechanisms that allow the cutting edge blade to be repositioned and reattached in different orientations. This dynamic reconfiguration capability enables the blade to be reversed or repositioned to expose fresh cutting teeth, extending its service life without requiring a fundamentally complex device structure.
Solution Approach 2:
The separation of the cutting edge blade from the holder plate allows the blade to be independently manipulated and repositioned. This segmentation enables simple reversal or reconfiguration of the blade on the holder plate, extending its usable life while maintaining device simplicity through the use of basic mechanical components.

AI summary
A cutting edge for agricultural use provides opposed cutting edges arranged to be rotationally symmetric about an axis so that the cutting edge may be reversed in the field to repair or replace the cutting edge without the need for separate spare parts. In some embodiments a support plate may provide a ledge stop supporting the unused cutting edge to absorb impact shocks without cutting edge damage.
