Soil Cultivation Roller Rings for Compaction and Soil Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rollers for soil cultivation face difficulties in achieving efficient soil compaction and levelling while maintaining ease of operation, often becoming sluggish due to soil adhesions and requiring complex configurations for different operating conditions.
Innovation Solution
A roller design featuring compaction rings with varying intermediate rings of different diameters and widths, allowing adaptation to diverse operating conditions, enhanced soil throughput, and improved compaction and levelling capabilities, along with scrapers and clearers to manage soil adhesions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If intermediate rings with larger diameter are used, then re-compaction and levelling of soil is improved, but throughput of soil becomes more difficult and friction increases
Solution Approach 1:
The roller surface is segmented into multiple intermediate rings with different diameters arranged in sequences. This segmentation allows different sections of the roller to perform different functions: some sections with larger diameter rings provide compaction and levelling, while sections with smaller diameter rings provide easier soil throughput and reduce friction. This resolves the contradiction by spatially distributing different functional characteristics along the roller surface.
Solution Approach 2:
Different regions of the roller surface are given different local qualities through the use of intermediate rings with varying diameters. Specific local sections have larger diameter rings optimized for compaction and levelling quality, while other local sections have smaller diameter rings optimized for reduced friction and easier throughput. This local differentiation allows the roller to simultaneously achieve both high compaction quality and ease of operation in different areas.
2Ease of operation
If intermediate rings with smaller diameter are used, then throughput of soil is easier, but re-compaction and levelling of soil is reduced
Solution Approach 1:
The roller surface is divided into multiple segments with intermediate rings of different diameters. Segments with smaller diameter rings are positioned to provide easy soil throughput and reduced friction, while segments with larger diameter rings are positioned to provide adequate compaction and levelling. This segmentation strategy resolves the contradiction by ensuring that no single section must compromise between throughput ease and compaction quality.
Solution Approach 2:
Different local sections of the roller are equipped with intermediate rings of appropriately sized diameters to match local soil cultivation requirements. Areas requiring easier throughput receive smaller diameter rings, while areas requiring better compaction receive larger diameter rings. This local quality differentiation allows the roller to optimize both throughput ease and compaction quality simultaneously across different regions.
3Reliability
If scrapers are arranged to contact intermediate rings, then soil adhesions are removed, but friction increases and roller becomes more sluggish
Solution Approach 1:
The scraper function is extracted and applied selectively only to intermediate rings with larger diameters that are prone to soil adhesion accumulation. Intermediate rings with smaller diameters are left without scrapers, allowing them to rotate freely with minimal friction. This selective extraction of the scraping function resolves the contradiction by removing soil adhesions where necessary while preserving ease of operation where possible.

AI summary
A roller for agricultural soil cultivation has at least one support body rotatably mounted about an axis of rotation and multiple compaction rings arranged spaced apart from one another next to one another on the support body and intermediate rings arranged between adjacent compaction rings. At least two intermediate rings have a different diameter and/or a different width.
