Air Seed Splitter for Balanced Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural seeding machines face issues with unbalanced air distribution and seed delivery due to varying hose lengths, leading to blockages and inefficiencies, especially in machines with multiple rows, where the complexity of hoses increases.
Innovation Solution
A splitter design that directs an air/seed mixture from a main hopper to multiple auxiliary hoppers, using a primary and secondary outlet configuration, where the secondary outlet diverts flow when the primary outlet is blocked, ensuring consistent seed distribution across all rows with reduced hose complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple hoses are run from the main seed hopper to individual auxiliary seed hoppers, then each auxiliary hopper can receive seed, but the varying hose lengths create unbalanced air distribution causing blockages on long runs and excess seed delivery on short runs
Solution Approach 1:
The patent combines multiple auxiliary hopper connections into a single common air supply line that branches to multiple hoppers. This merging approach eliminates the need for separate hoses from the main hopper to each auxiliary hopper, reducing hose complexity while maintaining reliable seed delivery to all hoppers through balanced air distribution.
Solution Approach 2:
The air supply system is segmented into a common supply line and individual branch connections to each auxiliary hopper. This segmentation allows the common line to maintain balanced air pressure while each hopper receives appropriate seed flow, resolving the blockage and excess delivery issues caused by varying hose lengths.
2Productivity
If the number of rows of seed units is increased for larger seeding machines, then the seeding capacity is improved, but the number of hoses connected to the main seed hopper increases adding to machine complexity
Solution Approach 1:
The patent merges multiple hose connections into a single common air supply line that serves multiple auxiliary hoppers. This allows the machine to accommodate more rows (increasing productivity) without proportionally increasing hose complexity, as the common line efficiently distributes air to all connected hoppers.
Solution Approach 2:
The common air supply line serves multiple functions by distributing air to multiple auxiliary hoppers simultaneously. This multi-functional design allows the system to scale to accommodate more rows without requiring separate dedicated hoses for each hopper, thus maintaining manageable complexity while increasing seeding capacity.
3Device complexity
If a single hose is used to provide air/seed mixture to more than one auxiliary seed hopper using a splitter, then the number of hoses is reduced, but the splitter design must prevent blockage while ensuring proper seed distribution
Solution Approach 1:
The patent designs the common air supply line with specific local characteristics including appropriate diameter, length, and branching configuration to maintain balanced air distribution. This local optimization ensures that each auxiliary hopper receives appropriate air pressure and seed flow, preventing blockages while ensuring reliable seed distribution across all hoppers.
Solution Approach 2:
The common air supply line acts as an intermediary between the main seed hopper and multiple auxiliary hoppers. This intermediary structure balances the air/seed mixture distribution before it reaches each individual hopper, preventing the blockage issues that would occur with direct connections while maintaining reliable seed delivery to all hoppers.

Function Achieved in This Case
The splitter design ensures balanced seed delivery across all rows, preventing blockages and reducing hose complexity, thereby improving the efficiency and reliability of seed distribution in agricultural seeding machines.
Implementation Method 1
The seed is entrained in an air/seed mixture that is delivered from the main seed hopper to the auxiliary seed hoppers
Implementation Method 2
The seed is entrained in an air/seed mixture
Implementation Method 3
The splitter divides an air/product mixture, e.g., air/seed mixture, from an air-powered distribution line, between two receptacles

AI summary
A splitter divides an air/product mixture flow, delivered thereto in an air-powered distribution line, between a primary and a secondary distribution channel, which may be flow-coupled to a product hopper or a hose flow-coupled to another product hopper or another splitter. The air/product mixture enters the inlet of the splitter along a first flow path and exits a primary outlet, flow-coupled to the primary distribution channel, along a second flow path generally in-line with the first flow path. Air/product flow is exhausted by a secondary outlet, which is flow-coupled to the secondary distribution channel, at a sideward flow path relative to the first and second flow paths. The velocity flow vector along which the air/product mixture is exhausted from the secondary outlet is at an angle perpendicular to the velocity flow vector along which the air/product mixture is received by the inlet of the splitter.
