Seed Boot Wedge Design for Precise Seed Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming furrows for planting seeds often create wide trenches, which can disrupt the orientation of seeds as they are placed, especially for oriented seeds.
Innovation Solution
The seed boot design features a narrower trench with a v-shaped wedge and angled lower walls, allowing for precise seed placement while maintaining seed orientation, and can optionally include a coulter to facilitate soil cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wide trench is created using traditional methods (double disc opener, single disc opener), then the trench can easily accommodate seed deposition, but the seed orientation cannot be maintained during placement
Solution Approach 1:
The seed boot creates a localized narrow trench geometry with specific angular walls that guide seed placement. The trench has a bottom width of 0.2-0.4 inches with angled walls (15-45 degrees from vertical) that provide directional guidance, allowing the seed to be placed precisely while maintaining its orientation. This local geometric configuration solves the contradiction by providing both ease of placement and precision control in the same structure.
Solution Approach 2:
The seed boot acts as an intermediary device between the seed tube and the soil. It receives seeds from the seed tube and channels them through a controlled narrow trench pathway before deposition into the soil. This intermediary structure maintains seed orientation during the transfer process, preventing the orientation loss that occurs with direct wide-trench methods.
2Manufacturing precision
If a narrow trench is created to maintain seed orientation, then seed placement precision is improved, but the trench may be more difficult to form through soil
Solution Approach 1:
The coulter performs preliminary action by cutting through the soil surface and creating an initial opening before the seed boot forms the narrow trench. This pre-cutting action reduces the resistance the seed boot encounters when forming the precise narrow trench, making the overall process easier while maintaining precision.
Solution Approach 2:
The invention merges the coulter (soil cutting device) with the seed boot (trench forming device) into a single integrated assembly. The coulter handles the initial soil penetration and breaking, while the seed boot follows immediately to form the precise narrow trench. This combination divides the difficult task of narrow trench formation into two easier sequential operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables the placement of seeds in the same orientation as they were received, reducing seed displacement and improving planting efficiency, especially for oriented seeds.
Implementation Method 1
Seed boot 700 has a leading edge 701. Leading edge 701 can have a knife shaped edge, which can help move through soil. Wedge 707 extends from leading edge 701 and ends before channel exit 705. Wedge 707 can be v-shaped.
Implementation Method 2
Lower walls 709 (709-1, 709-2) have an angle α with respect to vertical. The angles can range from 10 to 60 degrees, or from 15 to 45 degrees, or from 20 to 30 degrees from vertical.
