Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centrifugal spreaders and field sprayers face challenges in maintaining a consistent spreading pattern due to vehicle movements and uneven fertilizer distribution, leading to inefficiencies in fertilizer application and spray distribution.
Innovation Solution
A support structure with a coupling frame and mounting frame that are movably coupled via a bearing device, equipped with an adjusting device controlled by sensors to maintain a horizontal alignment of the working device, ensuring optimal spreading or spraying patterns despite vehicle movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the centrifugal spreader is rigidly coupled to the tractor via three-point linkage, then the implement follows the tractor's pitching and rolling movements, but the spreading pattern becomes dependent on ground conditions and vehicle position
Solution Approach 1:
The patent applies the dynamics principle by replacing the rigid three-point linkage with a support structure that enables relative movement between the implement and tractor. The mounting frame can pivot and adjust its position dynamically in response to tractor movements and ground conditions, allowing the spreading pattern to remain consistent regardless of vehicle position or terrain variations.
Solution Approach 2:
The support structure acts as an intermediary between the tractor and the centrifugal spreader. It includes a coupling frame that attaches to the tractor and a mounting frame that holds the spreader, with bearing devices that allow controlled relative movement. This intermediary structure decouples the spreader from direct rigid connection to the tractor, enabling independent positioning to maintain optimal spreading patterns.
2Stability of the object's composition
If the point of impact on the centrifugal disc changes due to uneven ballasting, then the spreading pattern is affected, but adjusting the ballasting is complex and time-consuming
Solution Approach 1:
The support structure incorporates sensors that automatically detect changes in implement position, inclination, or ballasting status. The system self-adjusts by triggering the adjusting device to modify the mounting frame position or ballasting configuration, eliminating the need for manual intervention and complex adjustment procedures by the operator.
Solution Approach 2:
The patent implements a feedback mechanism where sensors continuously monitor the implement's position, inclination, and ballasting distribution. This information is fed back to the control system, which automatically adjusts the mounting frame position or ballasting to maintain optimal spreading conditions, creating a closed-loop control system that compensates for variations in real-time.
3Stability of the object's composition
If the mounting frame position is adjusted to compensate for vehicle movements, then the spreading pattern improves, but the device complexity increases
Solution Approach 1:
The support structure is segmented into distinct functional components: a coupling frame for tractor attachment, a mounting frame for holding the spreader, bearing devices for enabling relative movement, and an adjusting device for active position control. This segmentation allows each component to perform its specific function efficiently while keeping the overall system manageable and maintainable.
