Oriented Seed Delivery Belt Assembly for Precision Planting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seed planting systems randomly deposit seeds without regard for orientation, which can affect plant growth and productivity.
Innovation Solution
A seed delivery assembly that includes belts and rollers to orient seeds in a desired position, such as pedicel down and flats to the side, ensuring proper planting orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If seeds are randomly dropped into the ground, then the device complexity is reduced, but the seed orientation precision deteriorates
Solution Approach 1:
The seed metering assembly performs preliminary orientation action on seeds before they are deposited into the ground. The metering mechanism includes features that align and orient seeds in the desired orientation (pedicel down, flats to the side) prior to delivery to the planting trough, ensuring proper planting orientation without requiring complex orientation mechanisms at the point of deposition
Solution Approach 2:
The patent introduces an intermediary seed metering assembly between the seed storage and the planting trough. This intermediate device handles the orientation function, allowing the simple planting trough to receive pre-oriented seeds. The metering assembly acts as a mediator that transforms random seed orientation into controlled orientation before final deposition
2Ease of operation
If seeds are randomly deposited, then the ease of operation is improved, but the plant growth quality deteriorates
Solution Approach 1:
The seed metering assembly performs preliminary orientation action on seeds before they are deposited into the ground. The metering mechanism includes features that align and orient seeds in the desired orientation (pedicel down, flats to the side) prior to delivery to the planting trough, ensuring proper planting orientation without requiring complex orientation mechanisms at the point of deposition
Solution Approach 2:
The seed metering assembly is designed to automatically orient seeds through its metering mechanism without requiring external intervention or complex control systems. The self-service feature allows the system to maintain seed orientation through the metering process itself, eliminating the need for additional orientation mechanisms while ensuring consistent plant growth quality
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
Improves seed germination and plant growth by maintaining the desired orientation during planting, leading to faster germination, healthier plants, and reduced weed growth.
Implementation Method 1
A first powered roller is engaged with the first belt, and the powered roller drives the first belt translation
Implementation Method 2
a first non-powered roller or guide is engaged with the first belt, and the first guide provides tension to the first belt as it translates
Data Source
AI summary
Techniques and/or systems are disclosed for depositing a seed in planting trough in a desired orientation. A system can be devised that receives a seed from a seed meter, and deposits in the ground in the prepared orientation as received from the meter. A seed delivery assembly can comprise one or more belts, each with an inner portion that operably moves downward. The inner portion receives and engages with an oriented seed delivered in a target orientation at the top portion and translates the oriented seed to the bottom portion, where it is ejected in the target orientation. A one or more powered rollers can be engaged with the one or more belts to provide rotational power for the translation. Further, one or more non-powered rollers or guides can be engaged with the pone or more belts to provides tension to the one or more belts during translation.
