Agricultural Roller with Integrated Ring Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil cultivation rollers face issues with soil accumulation between compaction rings, leading to reduced effectiveness, accelerated corrosion, and a shortened service life, as well as increased operational difficulty due to soil adherence.
Innovation Solution
The roller design incorporates compaction rings with intermediate rings of varying diameters and widths, bonded or integrated to form ring units, which enhance soil passage and reconsolidation, prevent soil ingress, and improve corrosion resistance, while using scrapers and wipers to manage soil adherence effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If compaction rings are arranged at intervals on the support tube, then soil can be compacted and leveled, but soil accumulates between the compaction rings reducing effectiveness and service life
Solution Approach 1:
The harmful element (soil accumulation between rings) is eliminated by integrating the intermediate ring with the compaction ring to form a solid ring unit, preventing soil from entering the gap between separate rings
Solution Approach 2:
The intermediate ring and compaction ring are materially bonded or formed integrally to create a unified ring unit structure, eliminating the gap where soil would accumulate and corrode the support tube
2Reliability
If scrapers are arranged below the axis of rotation to remove soil, then soil adherence is reduced, but the scrapers and soil impede rolling motion making it harder to pull
Solution Approach 1:
The intermediate ring with larger diameter is designed to intentionally contact the scraper, converting the harmful soil accumulation into a beneficial scraping action that cleans the roller surface while maintaining smooth rolling motion
3Ease of manufacture
If intermediate rings with uniform diameter are used, then manufacturing is simplified, but the roller cannot be adapted to different operating conditions and equipment combinations
Solution Approach 1:
Different intermediate rings are designed with different diameters and widths to match specific operating conditions and equipment combinations, allowing the roller to be optimized for different agricultural applications

AI summary
The present invention relates to a roller for agricultural soil cultivation, having at least one supporting body (18), which is mounted rotatably about an axis of rotation (22), and a plurality of compression rings (24), which are arranged next to one another and spaced apart from one another on the supporting body (18), for compressing the soil, and intermediate rings (26, 28) arranged between adjacent compression rings (24), wherein at least one first intermediate ring (26) and one second intermediate ring (28) are provided with different diameters (d1, d2) and/or different widths (b1, b2). According to the invention, the roller (10) has at least one ring unit (36) which comprises at least one compression ring (24) and at least one, in particular second, intermediate ring (26, 28), the intermediate ring (26, 28) being connected to at least one adjacent compression ring (24) with a material bond or being formed integrally with the compression ring (24).
