Positionable Seed Tank Linkage for Planter Refilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seed planters require operators to climb ladders or use extension devices to refill elevated seed tanks, which is inefficient and poses safety risks, and they often lack the flexibility to efficiently plant seeds in multiple rows with easy access for refilling and maintenance.
Innovation Solution
A seed planter assembly with positionable tanks that can be lowered to the ground for easy refilling and raised for dispensing, supported by a linkage system and hydraulic actuators, allowing for multiple seed hoses to distribute seeds in rows while maintaining operator safety and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the seed tank is elevated for dispensing seeds, then seed distribution capability is improved, but operator accessibility for refilling deteriorates
Solution Approach 1:
The seed tank is made dynamically positionable between two states: elevated for seed dispensing and lowered for refilling. The linkage system with actuators enables the tank to transition between these positions, allowing the system to adapt its configuration based on the operational phase, thus resolving the contradiction between seed distribution capability and operator accessibility.
Solution Approach 2:
The vertical position parameter of the seed tank is changed based on operational requirements. When refilling is needed, the tank position parameter is changed from elevated to lowered, making it accessible to operators at ground level. When seed distribution is the priority, the tank is positioned elevated. This dynamic parameter change resolves the accessibility contradiction.
2Productivity
If the seed tank is elevated for seed dispensing, then seed distribution efficiency is improved, but operator safety deteriorates due to climbing requirements
Solution Approach 1:
The system dynamically adjusts the tank position to eliminate safety hazards during refilling operations. By lowering the tank to ground level, operators no longer need to climb ladders or use extension devices, thus maintaining safety while preserving seed distribution efficiency during the dispensing phase when the tank is elevated.
Solution Approach 2:
The linkage system with actuators enables automatic positioning of the tank, reducing the need for manual intervention at heights. The system can self-adjust the tank position based on operational mode, eliminating safety risks associated with operator climbing while maintaining efficient seed distribution capability.
3Ease of operation
If the tank is positioned for easy refilling at ground level, then ease of operation is improved, but seed dispensing capability deteriorates
Solution Approach 1:
The seed tank is dynamically repositioned based on the operational phase. During refilling, the tank is at ground level for ease of operation. During seed dispensing, the tank is elevated to optimize seed distribution capability. This dynamic repositioning resolves the contradiction between ease of refilling and seed dispensing capability.
4Stability of the object's composition
If a fixed elevated tank structure is used, then seed distribution stability is improved, but adaptability for different operations deteriorates
Solution Approach 1:
The seed tank structure is made dynamic rather than fixed, allowing it to transition between elevated and lowered positions. This enables the system to maintain stability during seed dispensing when elevated, while also adapting to refilling operations when lowered, thus resolving the contradiction between stability and adaptability.
Solution Approach 2:
The positionable tank structure serves multiple functions: it provides stable elevated positioning for seed dispensing and accessible ground-level positioning for refilling. This multi-functionality resolves the contradiction between maintaining distribution stability and providing operational flexibility for different tasks.

AI summary
A seed planter assembly for planting seeds in rows throughout a field includes at least one tank for storing the seeds and a seed hose in communication with the at least one tank for delivering the seeds to the field. The seed planter assembly also includes a support frame for supporting the at least one tank and the seed hose, and a linkage assembly (e.g., including a four-bar linkage) coupled with the support frame and the at least one tank. The linkage assembly is configured for lifting the at least one tank from a first orientation proximate to a support surface to a second orientation spaced farther apart from the support surface. The seed planter assembly can also include an actuator (e.g., a hydraulic actuator) connected between the support frame and the linkage assembly for moving the at least one tank between the first orientation and the second orientation.
