Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural devices with dual distributor heads face issues such as increased weight, complexity, and maintenance difficulties due to multiple tubes, making them cumbersome for transportation and service.
Innovation Solution
A distributor head divided into two chambers with separate airflow paths for each granular material, allowing independent distribution and control of airflow to achieve precise and selective distribution of seeds and fertilizers without the need for two separate heads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two separate distributor heads are used to distribute two types of granular materials, then the distribution precision and selectivity are improved, but the device weight, volume, and complexity increase significantly
Solution Approach 1:
The patent combines two separate distributor heads into a single integrated distributor head with two chambers. Each chamber is dedicated to one granular material type, but both chambers share common structural elements including the housing, outlet mechanisms, and control systems. This merging reduces overall device weight and volume while maintaining the ability to independently control distribution of each material type through separate airflow paths and outlet covers.
2Measurement precision
If two separate distributor heads are used, then distribution precision is improved, but the number of tubes and components increases making maintenance difficult
Solution Approach 1:
The integrated distributor head design merges many individual components into unified structures. The two chambers share a common housing, airflow generation system, and outlet control mechanisms, reducing the total number of separate tubes and components that would require maintenance. The shared structure allows for easier access and repair while maintaining independent control capabilities.
3Measurement precision
If two separate distributor heads are used, then distribution precision is improved, but the device volume increases making transportation and folding difficult
Solution Approach 1:
The patent integrates two distributor head functions into a single compact unit with shared structural components. The two chambers are positioned adjacent to each other within a common housing, and share airflow paths and control mechanisms, significantly reducing the overall volume compared to two separate distributor heads. This compact integrated design facilitates easier transportation and folding while preserving independent distribution capabilities for each granular material type.
4Weight of moving object
If a single distributor head is used for both granular materials, then device weight and volume are reduced, but distribution precision and selectivity deteriorate
Solution Approach 1:
The distributor head is segmented into two distinct chambers, each dedicated to one granular material type. Each chamber has its own inlet, airflow path, and outlet covers, allowing independent control of material flow. This segmentation within a unified structure enables precise and selective distribution of each material type while maintaining reduced device weight and volume compared to completely separate distributor heads.
5Device complexity
If a single distributor head is used, then device complexity is reduced, but the ability to selectively distribute different granular materials deteriorates
Solution Approach 1:
The distributor head is segmented into two independently controllable chambers within a single integrated structure. Each chamber can be independently activated or deactivated through separate airflow control and outlet cover mechanisms, providing high distribution selectivity. This segmented design within a unified system reduces overall device complexity compared to two completely separate distributor heads while maintaining the ability to selectively distribute different granular materials to different locations.

Implementation Method 1
Two types of granular materials are supplied pneumatically and separately using a stream of air flowing from the hopper through the feed pipes to the distributor head
Implementation Method 2
The airflow carrying the first granular material is substantially opposite to the airflow carrying the second granular material when entering the distributor head

AI summary
The present invention relates to a method of distributing granular materials using an agricultural distribution device provided with a distributor head (1) divided into two separated chambers (41, 42). The distributor head (1) is provided with a plurality of evenly arranged outlets (3a, 3b) along the circumference of the chambers (41, 42). The granular materials are supplied pneumatically to the distributor head (1), wherein the first granular material is supplied to a bottom chamber (41) and the second granular material is supplied to the top chamber (42), wherein the airflows carrying the granular materials are substantially opposite when entering the chambers (41, 42) of the distributor head (1).
