Solution Overview

Problem

Existing agricultural separators face issues with rapid wear, limited high-speed operation, lengthy design making them difficult to control, and unsatisfactory grading due to the 'sticking' phenomenon which affects soil aeration, and are not effective in separating elements of varying sizes efficiently.

Innovation Solution

A compact separator system using a frame with a first rotary cultivator for digging and collecting elements, a second rotary brush for sorting, and a matrix or wire mesh sieve for size-based separation, leveraging centrifugal force for efficient separation and self-cleaning, with optional conveyor belt or pre-mesh for enhanced performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a conveyor belt with rods is used for separation, then elements can be separated by size, but the 'sticking' phenomenon occurs reducing hole size and causing fine sieving that compacts soil

Engineering Contradiction:
Improveseparation precisionVSAvoidsticking phenomenon
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies mechanical vibration to the sieve surface to prevent material from sticking to the rods. The vibration causes elements to bounce and slide across the surface rather than adhering, maintaining consistent hole sizes and preventing the compaction problem. This resolves the contradiction by enabling effective separation without the harmful sticking effect.

Inventive Principle:
Principle #18Mechanical vibration

2Manufacturing precision

If separation means are distributed over a long distance for effective separation, then separation effectiveness improves, but the separator becomes more difficult to control

Engineering Contradiction:
Improveseparation effectivenessVSAvoidease of control
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent combines multiple separation functions into a single integrated unit where the sieve, vibration mechanism, and element discharge are closely positioned. This merging maintains effective separation capabilities while improving controllability and reducing the overall length of the separator, making it easier to operate and position in the field.

Inventive Principle:
Principle #5Merging (Combining)

3Speed

If the mass of elements moves on the conveyor belt, then transport is achieved, but crushing of clods occurs resulting in deposition of earth on the surface of the rods

Engineering Contradiction:
Improvetransport speedVSAvoidclod crushing
Core Design Contradiction:
SpeedVSObject-generated harmful factors

Solution Approach 1:

The patent modifies the local quality of the conveyor surface by using a筛网 (sieve) structure with specific hole patterns rather than continuous rods. This allows earth to pass through while larger elements are separated, preventing the accumulation of crushed material on the surface and reducing further crushing of clods during transport.

Inventive Principle:
Principle #3Local quality
