Sowing Unit for Precise Multi-Granule Furrow Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sowing machines struggle to efficiently distribute multiple granular products, such as seeds and agrochemicals, in a controlled and varied manner within soil furrows, limiting the optimization of product effectiveness and application precision.
Innovation Solution
A sowing unit with a chassis, furrow opening and filling mechanisms, and multiple distribution assemblies for granular products, allowing for precise placement at various positions relative to the furrow opening and closing, including positions before, during, and after furrow filling, with independent hoppers and distribution systems for each product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate distribution systems are used for each granular product, then product distribution precision is improved, but device complexity increases
Solution Approach 1:
The distribution system is divided into multiple independent distribution assemblies, each dedicated to a specific granular product (seeds, fertilizers, agrochemicals). Each assembly includes its own hopper and distribution mechanism, allowing precise control over the placement of each product type while maintaining modular architecture that manages system complexity.
Solution Approach 2:
The sowing unit is designed as a multi-functional device capable of distributing multiple types of granular products simultaneously through different distribution assemblies. The common chassis, furrow opening mechanism, and selection mechanism provide universal support while allowing specialized distribution functions for each product type.
2Productivity
If multiple granular products are distributed simultaneously at different positions, then productivity is improved, but device complexity increases
Solution Approach 1:
Multiple distribution assemblies are integrated onto a single common chassis that shares the furrow opening mechanism, closing mechanism, and selection mechanism. This merging allows simultaneous distribution of multiple granular products at different positions along the furrow while consolidating support functions to avoid proportional increase in overall system complexity.
Solution Approach 2:
The selection mechanism dynamically directs granular products to different distribution positions (P1, P2, P3) along the furrow based on operational requirements. This dynamic positioning capability enables flexible simultaneous distribution of multiple products without requiring fixed complex infrastructure for each possible product combination.
3Reliability
If granular products are placed at specific relative positions in the furrow, then product effectiveness is improved, but device complexity increases
Solution Approach 1:
Each distribution assembly is positioned to deliver its specific granular product at a particular relative location within the furrow (P1 between opening and filling, P2 before opening, P3 after filling). This localized quality approach ensures optimal placement of seeds, fertilizers, and agrochemicals at their respective required positions, with each assembly tailored to its specific distribution function.
4Adaptability or versatility
If independent hoppers and distribution systems are used for each product, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system employs independent hoppers and distribution systems for each granular product, allowing flexible adaptation to different product types and application requirements. Each independent assembly can be configured for specific products (seeds, fertilizers, agrochemicals) while the modular design enables reconfiguration for different agricultural operations without redesigning the entire system.

AI summary
A system for distributing granular products into the soil includes a mechanism for opening a furrow in the soil, a mechanism for filling the furrow, and an assembly for distributing a granular product. The assembly for distributing granular product includes a main hopper, a first distribution mechanism for distributing a first granular product, and a first conveyor mechanism for carrying the granular product to the soil. The assembly for distributing granular product also includes a dispensing assembly for an additional or second granular product. The dispending assembly is configured to deposit the additional granular product to the soil at the location where the first granular product was deposited and at least one of before furrow opening mechanism and after the furrow closing mechanism.
