Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seed distribution systems face challenges in maintaining precision and accuracy at higher planting speeds, particularly in the transition between the seed meter and transporter, leading to issues such as missing or double seeds, especially with flat and long seeds like corn.
Innovation Solution
A seed capture device with a movable element and power transmission mechanism coupled to the seed disk, synchronized with a seed transport element, which includes a seed accelerator to adjust seed speed and ensure precise distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If planting speed is increased to cover large areas quickly, then productivity is improved, but seed distribution precision deteriorates leading to missing or double seeds
Solution Approach 1:
A seed accelerator acts as an intermediary device between the seed meter and the planter. It receives seeds from the seed meter, accelerates them through a controlled path, and delivers them to the planter at the correct timing and speed, ensuring precise seed distribution even at high planting speeds
Solution Approach 2:
The seed accelerator performs preliminary acceleration of seeds before they are deposited into the planter. This preliminary action ensures that seeds are properly positioned and moving at the correct speed before the actual planting occurs, maintaining precision during high-speed operation
2Productivity
If conventional seed conveyors are used to enable higher planting speeds, then productivity is improved, but reliability deteriorates due to seed failures in the transition between seed meter and transporter
Solution Approach 1:
The seed accelerator serves as a reliable intermediary that guarantees proper seed transition from the seed meter to the planter. It controls the seed flow through a defined acceleration path with mechanical elements that ensure each seed is properly captured and delivered, eliminating the reliability issues of conventional conveyors
Solution Approach 2:
The seed accelerator changes the speed parameter of seeds during their transit. It captures seeds at one speed from the seed meter and accelerates them to a different, optimized speed for planter deposition, ensuring reliable transition and proper timing at high planting speeds
