Adjustable Rolling Basket Assembly for Soil Pulverization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling basket assemblies for agricultural implements lack adjustability in depth and force settings, making them ineffective across varying soil types and conditions, leading to clogging in muddy conditions and inefficient pulverization of clods.
Innovation Solution
An adjustable rolling basket assembly with a hinge mechanism that allows independent variation of basket depth and force engagement, featuring a biasing member and adjustment rod system to adjust the position and magnitude of force applied, enabling the basket to engage or disengage from the soil surface as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rolling basket is fixed in position and force, then the structure is simple, but it cannot adapt to different soil types and conditions
Solution Approach 1:
The rolling basket assembly is made dynamic through the hinge mechanism that allows the second frame member to pivot relative to the first frame member. This enables the basket to adjust its position and engagement force with the soil, transforming a static structure into an adaptable system that can respond to varying soil conditions while maintaining operational effectiveness.
Solution Approach 2:
The system enables parameter changes by allowing adjustment of the basket's engagement depth and force through the hinge mechanism. The operator can modify the position of the second frame member relative to the first, thereby changing the engagement parameters to suit different soil types and working conditions, achieving versatility without requiring multiple fixed configurations.
2Productivity
If the rolling basket engages continuously with the soil, then pulverization is constant, but it clogs in muddy conditions
Solution Approach 1:
The hinge mechanism provides dynamic control over basket engagement, allowing the operator to adjust the engagement level based on soil conditions. In muddy conditions, the basket can be partially disengaged or adjusted to reduce clogging while maintaining sufficient contact for effective pulverization, thereby improving reliability across varying conditions.
Solution Approach 2:
The system allows real-time parameter changes in engagement depth and force through the hinge mechanism. When encountering muddy conditions, the operator can modify the engagement parameters to prevent clogging while maintaining adequate soil contact for pulverization, thus preserving productivity without sacrificing reliability.
3Force
If the rolling basket is heavily biased into engagement, then pulverization force is high, but it cannot be easily disengaged
Solution Approach 1:
The hinge mechanism provides dynamic control over engagement force, allowing the operator to adjust the biasing force applied to the rolling basket. The system enables easy transition between high-force engagement for effective pulverization and reduced-force or disengaged positions for transport or when working conditions change, improving ease of operation while maintaining high pulverization force when needed.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The assembly effectively accommodates different soil types and conditions by allowing adjustable depth and force settings, preventing clogging and improving soil pulverization, while allowing the basket to be easily switched between engaged and disengaged positions.
Implementation Method 1
a biasing member configured to move the first axis of rotation toward a rest position
Implementation Method 2
The biasing member generates a preload force, and where the preload force is adjustable independent of the location of the rest position
