Solution Overview

Problem

Existing machines for picking up and treating arable soil with stones or clods are inefficient on heavy, wet soils and have low productivity, requiring additional processing steps and costly protective hoods, and struggle with multi-layer soil structures.

Innovation Solution

A machine design that includes a loosening phase before the separating section, using a rotatable loosening tool with adjustable star bodies and variable gap settings between separating rollers, allowing for efficient separation of fines and solids without significant power consumption or design lengthening, enabling use on various soil structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a rotor is arranged above the ploughshare to press on the soil structure, then clod breaking effect is improved, but device complexity increases and costly protective hood is required

Engineering Contradiction:
Improveclod breaking effectVSAvoiddevice complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent extracts the loosening function from the separating device and places it in a receiving device with a loosening tool that acts on the soil before it enters the separating section. This separates the loosening function from the complex rotor mechanism, reducing device complexity while maintaining clod breaking effectiveness.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The loosening tool performs preliminary loosening action on the soil structure before the soil enters the separating section. This preliminary action breaks up clods in advance, reducing the load on the separating device and eliminating the need for protective hoods.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If additional processing steps are used for heavy soil, then separation quality is improved, but productivity decreases and setup times increase

Engineering Contradiction:
Improveseparation qualityVSAvoidproductivity
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The loosening tool performs preliminary loosening of heavy soil structures before separation, breaking up clods and improving soil structure in advance. This eliminates the need for additional processing steps during separation, maintaining high separation quality while increasing productivity and reducing setup times.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The loosening tool is designed with adjustable star bodies and variable gap settings that can be dynamically adapted to different soil structures, including heavy soils. This dynamic adjustability allows the machine to handle various soil types efficiently without requiring multiple processing steps.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If screen gaps are made fixed, then device complexity is reduced, but adaptability to different soil structures decreases

Engineering Contradiction:
Improvedevice complexityVSAvoidadaptability to soil structures
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The separating device incorporates adjustable screen gaps that can be varied according to different soil structures and working conditions. This dynamic adjustability allows the machine to adapt to various soil types while maintaining manageable device complexity through systematic adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics

4Manufacturing precision

If working speed is reduced to improve separation quality, then separation precision is improved, but productivity decreases

Engineering Contradiction:
Improveseparation precisionVSAvoidproductivity
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The loosening tool performs preliminary loosening of the soil structure before separation, breaking up clods and creating a more uniform soil flow. This preliminary action allows the separating device to operate at higher speeds while maintaining high separation precision, thus increasing productivity without sacrificing quality.

Inventive Principle:
Principle #10Preliminary action
