Grader Moldboard Mounting with Bump Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Grader machines experience damage and increased wear due to the full extension of cylinders and impacts on components when the moldboard is pushed to deviated positions during operation.
Innovation Solution
A system comprising brackets, actuators, and bump stops is used to retain the moldboard to the implement frame of a grader machine. The brackets are coupled to the moldboard and the implement frame, allowing for tilting and articulation. Bump stops are positioned on the implement frame to contact the brackets when the moldboard moves from an intermediate to a deviated position, limiting further deviation and absorbing impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the moldboard is allowed to move freely to deviated positions during operation, then the grading flexibility and adaptability are improved, but the components (brackets, cylinders) suffer from damaging impacts and increased wear
Solution Approach 1:
The patent applies beforehand cushioning by installing bump stops on the implement frame that contact the brackets when the moldboard articulates to deviated positions. These bump stops absorb impact loads and prevent full extension of cylinders, cushioning the components against damaging impacts while allowing the moldboard to achieve necessary deviated positions for grading flexibility
2Reliability
If bump stops are added to cushion the moldboard movement, then component durability and impact resistance are improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the mounting assembly into distinct functional components: brackets coupled to the moldboard, actuators for tilting the brackets, and bump stops for impact absorption. This modular segmentation allows each component to perform its specific function independently, making the system easier to manufacture, assemble, and maintain while achieving the durability benefits
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 system effectively cushions the movement of the moldboard, reducing damage and wear on components, improving durability and impact loading resistance, and extending the useful life of the moldboard assembly.
Implementation Method 1
The bump stops are coupled to the implement frame and are configured to contact the respective brackets when the moldboard articulates from an intermediate position to one or more deviated positions

AI summary
A system for retaining a moldboard to an implement frame of a grader machine includes one or more brackets, one or more actuators, and one or more bump stops. The brackets are coupled to a backside of the moldboard and are coupled to the implement frame about an axis. The actuators are coupled to respective brackets and are configured to tilt the brackets with respect to the implement frame about the axis to articulate the moldboard with respect to the implement frame. The bump stops are coupled to the implement frame and are configured to contact the respective brackets when the moldboard articulates from an intermediate position to one or more deviated positions.
