Mower Reel Grinding via Rear Frame Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mower reel grinding systems require complex and time-consuming setup procedures to achieve optimal sharpening, leading to inconsistent and inaccurate results due to varying configurations of different mower units from different manufacturers and models.
Innovation Solution
A mower reel grinding system with moveable mounting brackets that secure to the rear roller or rear frame of the mower unit, allowing for horizontal positioning based on the unit's characteristics, combined with a microprocessor controller and linear distance gauge for precise alignment and adjustment of the grinding head, enabling quick and accurate setup and sharpening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional grinding systems secure the cutting reel using the front roller, then the cutting reel can be positioned for grinding, but the setup procedure becomes complicated and time-consuming due to varying mower unit configurations and front roller position changes
Solution Approach 1:
The patent introduces mounting brackets as an intermediary component between the mower unit and grinding system. These brackets attach to the rear roller or frame instead of directly using the front roller, serving as a stable reference point that mediates the connection and simplifies the positioning process regardless of front roller configuration variations
Solution Approach 2:
The patent creates a standardized mounting interface through the brackets that copies or replicates a consistent reference framework across different mower unit types. This standardized interface allows the grinding system to work with various mower configurations without requiring custom setup procedures for each unit
2Adaptability or versatility
If the front roller position is changed to enable attachment installation, then attachments can be installed, but access to the front roller becomes difficult and positioning accuracy decreases
Solution Approach 1:
The patent extracts the positioning function from the front roller by introducing separate mounting brackets that attach to the rear roller or frame. This separates the attachment installation requirement from the grinding positioning requirement, allowing the front roller to be repositioned for attachments while the brackets maintain accurate positioning for grinding operations
3Adaptability or versatility
If conventional grinding systems are used with different mower unit configurations, then various mower types can be serviced, but consistent and accurate sharpening becomes difficult to achieve
Solution Approach 1:
The mounting brackets are designed with universal adaptability to work with different mower unit configurations while maintaining consistent positioning. The brackets can be adjusted or configured to accommodate various rear roller positions and frame types, providing a universal solution that ensures accurate and consistent sharpening across different mower models and manufacturers
