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

VSEngineering 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

Engineering Contradiction:
Improvesoil cultivation effectivenessVSAvoidservice life
Core Design Contradiction:
ProductivityVSReliability

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

Inventive Principle:
Principle #2Taking out (Extraction)

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

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improvecorrosion resistanceVSAvoidrolling resistance
Core Design Contradiction:
ReliabilityVSEase of operation

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

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

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

Engineering Contradiction:
Improvering uniformityVSAvoidoperational adaptability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

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

Inventive Principle:
Principle #3Local quality

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).
