Soil Roller Outer Ring Support Groove Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing design of wedge ring rollers experiences increased wear and stability issues with the outer soil compacting rings due to inadequate support and dirt accumulation in the clamping area, leading to reduced functionality and service life.
Innovation Solution
The outer soil compacting rings are enhanced with a support groove of larger diameter than the retaining groove, providing additional lateral support and preventing dirt penetration, while the clamping discs include a support section that engages with the groove for secure attachment and improved sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the clamping disc is enlarged with a support edge to improve support for outer soil compaction rings, then the support and stability are improved, but dirt accumulates in the area of the clamping disc and soil compaction rings, leading to increased wear and reduced service life
Solution Approach 1:
The clamping disc is segmented into functional zones: a support edge for structural support and stability, and a smooth clamping surface for secure attachment. This segmentation prevents dirt accumulation by eliminating crevices while maintaining both support and clamping functions separately.
Solution Approach 2:
Instead of adding complex support structures that create dirt-trapping crevices, the invention inverts the approach by using a smooth, continuous clamping surface that inherently prevents dirt accumulation while still providing necessary support through the support edge configuration.
2Device complexity
If conventional clamping discs are used to secure soil compaction rings, then the attachment is simple, but the outer soil compaction rings are subject to increased wear and stability problems
Solution Approach 1:
The clamping disc design is segmented into a support edge for structural stability and a smooth clamping surface for secure attachment. This simple yet effective segmentation provides enhanced support for outer rings without complicating the overall device structure.
Solution Approach 2:
Different regions of the clamping disc have different properties: the support edge provides structural support and stability, while the clamping surface provides secure attachment. This local differentiation of qualities addresses the specific needs of different areas without increasing overall complexity.

AI summary
The invention relates to a soil roller for strip compaction of soil or earth, comprising a support body (11) rotatably mounted about its longitudinal axis, preferably cylindrical or tubular, and several soil compaction rings (12, 12a) arranged side by side on the support body (11). A spacer ring (14) is arranged between each pair of soil compaction rings (12, 12a). The soil compaction rings (12, 12a) have retaining grooves (15) for the lateral engagement of the spacer rings (14), preferably in the side surfaces or flanks of the soil compaction rings (12, 12a). The invention is characterized in that each of the two outer soil compaction rings (12, 12a) has at least one support groove (25) on the support body (11), which is provided for the engagement of a support section (24) connected to the support body (11).
