Air Seeder with Bulk and Singulating Meters for Row Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current seeding implements for row crops are not suitable for solid seeded crops, leading to reduced yield potential and high costs for farmers who want to transition to more profitable row crops like corn and soybeans, as existing seeding implements for solid seeded crops cannot deliver seeds singly and are not adaptable for narrower row spacings.
Innovation Solution
An air seeder apparatus with a frame-mounted furrow opener assembly system that includes both bulk and singulating seed meters, allowing for flexible configuration between conventional and singulating modes, enabling seeding at various row spacings by adjusting the furrow opener lift system and connecting/disconnecting the nurse system and bulk meter, thereby accommodating both wide and narrow row spacings without the need for separate equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single seeding implement is used for both solid seeded crops and row crops, then equipment cost is reduced and versatility is improved, but the device complexity increases and configuration adaptability becomes more difficult
Solution Approach 1:
The seeding implement is divided into separate functional modules: a bulk metering system for solid seeded crops and individual singulating metering systems for row crops. Each module can be independently activated or deactivated, allowing the implement to handle different crop types without requiring complete system redesign. The frame structure is also segmented to accommodate both narrow and wide row spacing configurations.
Solution Approach 2:
The seeding implement is designed with universal components that can serve multiple functions. The furrow openers are positioned to accommodate both narrow row spacing (6-12 inches) for solid seeded crops and wide row spacing (20-36 inches) for row crops. The seed delivery system can switch between bulk delivery and singulated delivery modes, making the same implement suitable for different crop types and planting patterns.
2Productivity
If bulk metering is used for solid seeded crops, then seeding speed and productivity are improved, but manufacturing precision of seed spacing deteriorates
Solution Approach 1:
An air distribution system acts as an intermediary between the bulk meter and the furrow openers. The bulk meter delivers seeds in bulk to a central location, and the air stream distributes them to multiple furrow openers simultaneously. This intermediary system maintains the high productivity of bulk metering while achieving relatively uniform seed spacing through controlled air flow distribution.
3Manufacturing precision
If singulating metering is used for row crops, then manufacturing precision of plant spacing is improved, but device complexity and cost increase
Solution Approach 1:
Instead of using a single complex singulating meter for each row position, the system uses multiple simpler singulating meters that can be selectively activated. Each singulating meter is a simplified version that handles one or more rows, and the same meter design can be copied and replicated across different positions. This reduces the complexity of individual meters while maintaining overall precision.
4Manufacturing precision
If separate seeding implements are purchased for row crops and solid seeded crops, then manufacturing precision for each crop type is optimized, but loss of capital and operational efficiency deteriorate
Solution Approach 1:
The patent merges the functionality of separate row crop planters and solid seeded crop seeders into a single unified implement. The frame structure, furrow opener system, and seed delivery mechanisms are combined into one platform that can be configured for different crop types. This consolidation eliminates the need for farmers to purchase and maintain separate implements, reducing capital investment while maintaining crop-specific seeding precision through selectable configurations.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The air seeder apparatus allows for efficient seeding of both row and solid seeded crops at desired spacings, providing even plant spacing and reducing conversion costs, enabling farmers to economically transition to more profitable crops while maintaining yield potential.
Implementation Method 1
a bulk meter at the bottom, typically again comprising a grooved roller or auger, which feeds seeds in bulk into an air stream which carries the seeds through a network of conduits to each furrow opener

AI summary
An air seeder apparatus has a frame and a plurality of furrow opener assemblies spaced across a width of the frame at a narrow row spacing, and a plurality of bulk product containers and a bulk meter mounted on each, one of which dispenses seeds through a distribution network to a seed tube on each furrow opener assembly. A plurality of singulating meter is provided, each dispensing singulated seeds to the furrow opener on one of the furrow opener assemblies. During singulating operation seeds are delivered to the singulating furrow opener assemblies only by the singulating seed meter, and during conventional operation seeds are delivered to the singulating furrow opener assemblies only by the bulk meter. A lift system, when in a singulating mode, maintains idle conventional furrow opener assemblies in the transport position while moving singulating furrow opener assemblies between the operating position and the transport position.
