Spreader Grader Blade Alignment via Segmented Hydraulic Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spreader/grader systems have limitations where only one end of the grader blades can move, restricting their alignment and operation in parallel or non-parallel configurations, which affects their efficiency in material distribution and deposition.
Innovation Solution
The improved spreader/grader system features a frame with parallel sidewalls and multiple blades that can be secured in fixed positions between the sidewalls, with hydraulic cylinders allowing each blade to move along the sidewall in parallel or non-parallel relationships, enabling flexible positioning and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only one end of the grader blades is allowed to move along an axis while the second end is fixed, then the structure is simple, but the blades cannot be aligned in different positions from one another and always work in parallel formation
Solution Approach 1:
The blade assembly is segmented into multiple independent movable ends. Each end of the grader blades is equipped with its own adjustment mechanism (hydraulic cylinder or manual adjustment member), allowing independent movement and alignment of each blade end along the sidewalls, rather than moving as a single unified structure
Solution Approach 2:
The blade system transitions from a static fixed-ends configuration to a dynamic adjustable system. The hydraulic cylinders or manual adjustment members enable real-time changes in blade position and angle, allowing the blades to adapt between parallel and non-parallel configurations based on operational needs
2Adaptability or versatility
If the blades are fixed in their relation to the surface itself and cannot rotate about an axis, then the structure is stable, but the blades cannot be positioned in various angles to prevent material accumulation
Solution Approach 1:
The blade system incorporates dynamic adjustment capabilities through hydraulic cylinders or manual adjustment members that allow the blades to rotate and reposition themselves. This enables the blades to change angles and orientations to prevent material accumulation and optimize material deposition according to operational requirements
Solution Approach 2:
The adjustment mechanisms are designed to be operable by the driver or operator without requiring external assistance. The hydraulic system or manual adjustment members allow the operator to independently control blade positioning and angle adjustment during operation

AI summary
An improved spreader/grader system, which includes a frame having a pair of parallel sidewalls; a plurality of spreader/grader blades positioned between the sidewalls and secured within a slot along the length of each of the sidewalls, each blade having a lower edge for spreading or grading a surface upon which the spreader/grader rests; a hydraulic cylinder attached to each end of each blade to allow each blade to be moveable along the length of the sidewall in a parallel or non-parallel relationship as desired by the operator; and a hydraulic cylinder system for attaching the frame to a vehicle, such as a tractor, for pulling the spreader/grader during the spreading/grading process. The blades of the spreader/grader may alternatively be secured in fixed positions between the sidewalls of the frame with a bolt/nut combination.
