Seed Metering Mixing System for Rotary Broadcaster
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seed rotary dispensers in agricultural equipment lack effective standardization of seed flow during planting, as they do not adequately integrate the mixing of particulate solids with seeds before sowing, leading to inconsistent seed treatment and distribution.
Innovation Solution
A metering and mixing system positioned between the grain bin and the rotary dispenser, utilizing a feed cone to direct seeds into a cylindrical mixing compartment where particulate solids are metered and mixed by a propeller, driven by a gear set connected to the planter's transmission system, ensuring uniform seed treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If seeds are directly dispensed from the grain bin without mixing, then the device complexity is reduced, but the seed flow standardization and treatment uniformity deteriorate
Solution Approach 1:
The patent combines the grain bin, mixing compartment, and rotary dispenser into a single integrated assembly. The mixing compartment is positioned within the grain bin structure, and the rotary dispenser is coupled to the mixing compartment, creating a compact unified system that provides both mixing and dispensing functions without requiring separate complex mechanisms.
Solution Approach 2:
The grain bin serves multiple functions: it acts as a storage container for seeds, a mixing chamber for combining seeds with particulate solids, and a support structure for the rotary dispenser. This multi-functionality reduces the need for additional dedicated components, thereby managing device complexity while achieving standardized seed flow.
2Reliability
If particulate solids are added to seeds for treatment, then the seed treatment effectiveness is improved, but the mixing uniformity deteriorates without proper mixing mechanisms
Solution Approach 1:
The system performs preliminary mixing of seeds with particulate solids in the mixing compartment before the seeds are dispensed. This pre-mixing action ensures that the treatment is uniformly applied to all seeds before they enter the dispensing phase, achieving consistent seed treatment effectiveness.
Solution Approach 2:
The mixing compartment acts as an intermediary chamber between the grain bin and the rotary dispenser. It provides a controlled environment where seeds and particulate solids can be thoroughly mixed before being fed to the dispenser, ensuring uniform composition and consistent treatment application.
3Manufacturing precision
If a mixing system is added between the grain bin and rotary dispenser, then the seed treatment uniformity is improved, but the device complexity increases
Solution Approach 1:
The mixing compartment is nested within the grain bin structure, and the rotary dispenser is nested within or coupled to the mixing compartment. This nested arrangement allows the mixing system to be integrated into the existing grain bin geometry, minimizing additional structural complexity while achieving uniform seed treatment.

AI summary
A metering and mixing system of solid particulates for a rotary seed dispenser in agricultural equipment for sowing, wherein the rotary seed dispenser is mounted under a seed feeder. The rotary seed dispenser is driven at the bottom by a planter drive system, which provides rotation to a spinning disc provided with a number of calibrated orifices through which the seeds housed in the disc orifices fall on a given point of the agricultural equipment. The metering and mixing system of solid particulates includes a solid particulate feeder that is positioned between the seed feeder and the rotary seed dispenser.
