Seed Drill Ridging Bodies for Organic Matter Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current seed ridge formation methods are inefficient, as they often clog seed coulters with unincorporated organic matter, restrict herbicide effectiveness, and require multiple operations, leading to weed infestation, stunted growth, and moisture loss due to inadequate reconsolidation and root penetration issues.
Innovation Solution
A method and device that consolidate organic matter and fertilizer into a seed dam below the seed level in a single operation, using subsoilers and disc coulters to prepare the rooting horizon, and ridging bodies to form and reconsolidate the seed dam, allowing for efficient seed placement in corn and potato cultivation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional seed ridge formation methods are used, then seed placement can be achieved, but unincorporated organic matter clogs seed coulters and restricts herbicide effectiveness
Solution Approach 1:
The patent applies preliminary action by forming the seed ridge and incorporating organic matter into the ridge structure BEFORE seed placement. The ridging bodies create a raised bed with organic matter integrated into its structure, eliminating the clogging problem that occurs when organic matter is present at the surface during conventional seed placement operations.
Solution Approach 2:
The patent extracts the organic matter from the seed placement path by incorporating it into the ridge structure. The ridging bodies move organic matter to the sides and integrate it into the ridge, leaving the seed placement area clear of obstructions while still providing fertilizer benefits.
2Reliability
If multiple operations are used for seed ridge formation, then thorough soil preparation can be achieved, but time and effort increase significantly
Solution Approach 1:
The patent merges multiple soil preparation operations into a single pass. The device combines ridging, organic matter incorporation, and seed placement functions into one integrated operation, eliminating the need for separate ploughing, smoothing, rolling, and harrowing operations while maintaining thorough soil preparation quality.
Solution Approach 2:
The ridging bodies perform multiple functions simultaneously: they form the raised ridge structure, incorporate organic matter into the ridge, prepare the seed placement area, and create the final seed bed configuration. This multi-functionality eliminates the need for multiple specialized operations.
3Shape
If conventional ridge shaping equipment is used, then ridge formation can be achieved, but organic matter is mixed throughout the ridge causing weed infestation and stunted growth
Solution Approach 1:
The patent applies local quality by controlling the distribution of organic matter within the ridge structure. The ridging bodies incorporate organic matter specifically into the ridge body rather than mixing it uniformly throughout, creating localized zones of fertility while maintaining clean seed placement areas, thus preventing weed infestation and stunted growth.
4Ease of operation
If inadequate reconsolidation is used, then seed placement can be simplified, but moisture loss occurs and root penetration is impaired
Solution Approach 1:
The patent applies preliminary action by reconsolidating the seed ridge structure BEFORE seed placement. The ridging bodies compact and firm up the ridge material in advance, creating a stable structure that will retain moisture and support good root penetration, eliminating the need for subsequent reconsolidation operations.

AI summary
A seed drill for drilling seed into ridges, e.g. maize, has deep tines (2) and disc harrows (6) to loosen the earth followed by disc harrows (3) to collect organic material into a strip to be covered by ridge forming disc harrows (4) and shaped rollers (5) to prepare the ridges. The seed is dropped into the ridge and secured by following rollers (11). The drill is further fitted with fertilizer dispensers (8). The ridge forming disc harrows are concave. The whole process is completed in one pass.
