Adjustable Deflectors for Uniform Air Distribution in Agricultural Sprayers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air distribution apparatuses in agricultural sprayer machines suffer from non-uniform air flow and pesticide distribution, leading to inefficient treatment and increased costs due to constructive complexity and high production costs.
Innovation Solution
The improved air distribution apparatus features deflector means coupled with the inner wall of the tubular casing, ensuring a homogeneous and balanced air flow along the entire length, eliminating the need for a gap element and simplifying the construction, resulting in uniform pesticide distribution and reduced production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional air distribution apparatus with elongated slot and uniform nozzle arrangement is used, then device complexity is reduced, but air flow uniformity and pesticide distribution homogeneity deteriorate
Solution Approach 1:
The patent applies local quality by making the deflector means adjustable rather than uniform throughout. Each deflector can be independently positioned to optimize air flow distribution at different locations along the tubular casing, allowing localized adjustment to compensate for pressure variations and achieve uniform air flow without requiring complex fixed structures
Solution Approach 2:
The deflector means are designed to be movable and adjustable, allowing dynamic optimization of air flow distribution. This dynamic capability enables the system to adapt to different operating conditions and achieve uniform air flow distribution without requiring a complex fixed structure, thus resolving the contradiction between simplicity and precision
2Manufacturing precision
If gap element is added to improve air flow distribution, then air flow uniformity improves, but device complexity and production costs increase
Solution Approach 1:
The patent extracts the air flow distribution function from a separate gap element and integrates it into adjustable deflector means that are part of the nozzle assembly. This eliminates the need for a complex gap element while maintaining the ability to achieve uniform air flow distribution through localized adjustment of the deflectors
Solution Approach 2:
The deflector means serve multiple functions: they redirect air flow, adjust spray pattern, and compensate for pressure variations. By combining these functions into a single adjustable component, the patent eliminates the need for separate gap elements and reduces overall device complexity while maintaining air flow uniformity
3Device complexity
If air is pumped from upper part of distribution apparatus, then device complexity is reduced, but air flow balance and pesticide distribution uniformity deteriorate
Solution Approach 1:
The patent applies local quality by allowing different sections of the tubular casing to have independently adjustable deflectors. This enables localized compensation for the pressure gradient created by air pumping from the upper part, ensuring uniform pesticide distribution despite the simplified air supply structure
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 solution achieves a more uniform and effective treatment of plantations by ensuring balanced air and pesticide distribution, reducing operational and production costs while maintaining efficient treatment coverage.
Implementation Method 1
deflector means firmly coupled with the inner wall of the tubular casing and adapted to ensure a homogeneous, uniform and balanced distribution of air, exiting the tubular casing
Implementation Method 2
the air coming from the atomizer flows inside the elongated casing itself... supply of air from the air distribution apparatus slot and the simultaneous feeding of the treatment liquid from the nozzles cause the emission of a strong jet of nebulized pesticide substance
