Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing dual row seeding equipment does not effectively promote germination and maximize yield due to inadequate soil adaptation for seed delivery.

Innovation Solution

A seeding boot with downwardly facing, rearwardly inclined surfaces forms parallel slots in the soil to create seed beds, accompanied by a digging shank that forms a trough, and a fertiliser delivery system to optimize seed and fertiliser placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional multiple-pass ploughing and seeding method is used, then seed planting can be completed, but soil structure is destroyed and moisture is lost

Engineering Contradiction:

Improveseed planting efficiencyVSAvoidsoil structure destruction

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent combines the ploughing and seeding operations into a single pass by integrating a seeding boot with a plough assembly. The seeding boot is positioned to receive seed directly as the plough cuts the soil, eliminating the need for separate sequential operations and reducing the number of passes required while maintaining soil structure integrity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent performs seed placement and soil preparation in advance during the same operational pass. The digging blade creates a slot and the seeding boot deposits seed into the slot simultaneously, preparing the seed bed before the soil surface is fully disturbed, thereby preserving moisture and soil structure while completing the planting task.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If dual row seeding equipment is used, then planting efficiency is improved, but soil area adaptation for germination is inadequate

Engineering Contradiction:

Improveplanting efficiencyVSAvoidinadequate soil adaptation for germination

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent creates distinct soil conditions at different locations within the same planting operation. The digging blade forms a central slot while the seeding boot creates lateral seed beds with different soil displacement characteristics. This local differentiation provides optimal soil conditions for germination and early growth while maintaining the efficiency of dual-row planting.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent divides the seed delivery system into multiple independent components: a digging blade for creating central slots and a seeding boot with multiple outlets for delivering seed to lateral positions. This segmentation allows each component to perform its specific function optimally - the blade for deep soil cutting and the boot for precise seed placement - thereby improving both efficiency and soil adaptation for germination.

Inventive Principle:

Principle #1Segmentation

AI summary

A plough assembly (10) to be drawn by a plough frame that is attached to a prime mover. The assembly (10) includes a digging shank (14) attached to a clamp (11) that is to be attached to the plough frame. Attached to the lower end of the shank (14) is a digging assembly (21). The digging assembly (21) includes a mounting (22) and a digging blade (23). Behind the digging blade (23) is a twin road seeding boot (76). Following the boot (76) is a press wheel (68), with the seeding boot (76) having a transverse width greater than the transverse width of the blade (23).
