Double Loop Barbed Links for Rolling Basket Soil Finishing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural tillage implements, such as rolling baskets, often leave coarse soil clods and debris on the surface due to limited cutting depth and blade wear, failing to create a smooth and fine soil strip effectively.
Innovation Solution
A rolling basket assembly with a bracket, rotatably connected disks, and interlocking double loop barbed chain assemblies that span between the disks, engaging the soil to break up clods and debris, creating a smooth and fine soil strip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional rolling baskets with blades are used for soil finishing, then the blades can break up dirt and sod clods, but the limited cutting depth and blade wear cause coarse objects and debris to remain on the soil surface
Solution Approach 1:
The patent changes the fundamental parameter of the soil-engaging element from flat blades to three-dimensional barbed links with projections. This structural parameter change enables the links to penetrate deeper into the soil and break up clods more effectively, resolving the limitation of cutting depth while maintaining soil surface finishing capability.
Solution Approach 2:
The chain assembly combines multiple functional elements (loops for connectivity, barbs for engagement, projections for penetration) into a composite structure. This composite design integrates both the soil-breaking function and the chain connectivity function, allowing the system to handle both deep clod breaking and surface finishing simultaneously.
2Productivity
If traditional rolling baskets with blades are used, then soil can be broken up, but the blades fail to create a smooth and fine soil strip due to wear and limited cutting depth
Solution Approach 1:
The barbed link structure concentrates the soil-breaking action at specific locations (the barbs and projections) rather than distributing it across a broad blade surface. This localized quality enhancement allows deep penetration and effective clod breaking at contact points while the interlocking chain structure maintains overall soil surface smoothness and fineness.
3Ease of manufacture
If double loop barbed links are used in chain assemblies, then manufacturing cost and assembly time are reduced, but the structure must still effectively engage soil and create fine strip
Solution Approach 1:
The double loop barbed link is designed as a universal component that performs multiple functions: it provides structural connectivity as a chain link, engages soil through its barbed structure, and breaks up clods via its projections. This multi-functionality eliminates the need for separate components, reducing assembly time and cost while maintaining effective soil engagement capability.

AI summary
A rolling basket assembly for an agricultural tillage implement. The rolling basket assembly includes a bracket, a first disk and a second disk rotatably connected to the bracket, a plurality of chain assemblies. Each chain assembly includes a first end connected to the first disk and a second end connected to the second disk and a plurality of links looped around one another and collectively forming each chain assembly. Each link includes a first loop, a second loop that is looped around the first loop, and at least one projection extending outwardly from one of the first loop and the second loop.
