Agricultural Disc Support Structure for Material Flow and Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural equipment with parallel disc configurations experiences issues with material obstruction and uneven force distribution due to small spacing between disc rows and perpendicular force transfer, leading to material heaps and excessive bending efforts.
Innovation Solution
A structural element with a trapezoidal-shaped profile formed by transverse beams and support bars, allowing for an open region for material flow and angular force distribution, reducing material obstruction and improving force absorption.

Engineering Contradiction Analysis
1Speed
If parallel disc configurations are used with small spacing between disc rows, then equipment can operate at higher displacement speeds, but material obstruction and formation of heaps occur
Solution Approach 1:
The patent changes the spatial arrangement from a conventional parallel configuration to a tapered configuration where disc rows are arranged at different longitudinal positions. This dimensional reorganization creates increased free space between disc rows, allowing material to flow freely without obstruction while maintaining high displacement speeds.
2Device complexity
If parallel disc configurations with perpendicular force transfer are used, then structural simplicity is maintained, but great bending effort acts on supporting rods
Solution Approach 1:
The patent introduces asymmetry in the structural arrangement by positioning transverse beams at different longitudinal distances from the disc axis. This asymmetric configuration causes forces to act at angular orientations rather than perpendicular to the supporting rods, thereby reducing bending moments while maintaining structural simplicity.
3Force
If transverse beams are positioned close to the disc axis, then force distribution improves, but free space for material flow decreases
Solution Approach 1:
The patent segments the structural support system into multiple transverse beams positioned at different longitudinal locations. This segmentation allows each beam to handle specific force components while collectively providing adequate free space for material flow between the disc rows, resolving the conflict between force distribution and material flow space.

AI summary
Described is a structural element for agricultural equipment comprising at least one pair of transverse beams associated with at least one pair of support bars of a set of agricultural discs, where the longitudinal distance between the beams of the pair of transverse beams is smaller than the longitudinal distance between the bars of the pair of support bars. This construction allows a greater free space for the flow of material cut by the discs (soil and plant residues) and a decrease in the occurrence of stops to clear the obstruction or even the formation of “heaps” on the ground, while still promoting an adequate arrangement for the absorption and dissipation of efforts that act on the structural element.
