Multiple Nozzle Holder Mounting for Stable Chemical-Isolated Spraying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural spray nozzles are prone to mechanical components being immersed in the spraying fluid, leading to product contamination, reduced service life due to chemical interaction, and mechanical instability due to weight distribution.
Innovation Solution
A nozzle holder design with a movable plate and actuator system that isolates mechanical components from the fluid, allowing remote control and simultaneous operation of multiple valves, and a fixing device that secures the nozzle holder to the supply line to prevent pivoting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If mechanical components are placed in the fluid path for compact design, then device complexity is reduced, but product contamination and chemical corrosion occur
Solution Approach 1:
The nozzle holder is divided into two separate compartments: a first compartment housing mechanical components (actuator, plate, valves) and a second compartment for fluid distribution (inlet pipe, distribution chamber, outlet pipes). This segmentation isolates mechanical parts from the spraying fluid, preventing contamination while maintaining compact design.
2Ease of manufacture
If mechanical components are exposed to chemical agents for simplified structure, then manufacturing is easier, but service life is reduced due to corrosion
Solution Approach 1:
By separating mechanical components into a dedicated first compartment isolated from the fluid path, the mechanical parts are protected from chemical corrosion. This allows use of standard materials with longer service life while maintaining manufacturing simplicity through the modular compartment design.
3Device complexity
If nozzle holder housing contains majority of mass for integrated design, then device complexity is reduced, but mechanical instability occurs due to pivoting
Solution Approach 1:
The supply line extends between the first compartment (housing mechanical components) and the second compartment (housing fluid distribution elements), creating a spatial arrangement that balances the mass distribution along the longitudinal axis. This dimensional arrangement prevents pivoting by distributing weight evenly, while maintaining integrated design through the connected compartments.
4Ease of operation
If manual operation is required for nozzle selection, then ease of operation is reduced, but device complexity is reduced
Solution Approach 1:
The actuator automatically actuates the plate to rotate it into position, causing valves to open or close based on the plate's angular position. This self-service mechanism eliminates the need for manual intervention in nozzle selection, improving ease of operation while the automated control system manages the increased complexity.
