Slit-Shaped Induction Nozzle for Agricultural Sprayer Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing induction bowls in agricultural field sprayers have inefficient nozzle arrangements that hinder the compact design and effective flushing of plant treatment agents and fertilizers, leading to suboptimal mixing and distribution within the sprayer.
Innovation Solution
The induction nozzles are redesigned with slit-shaped outlet openings oriented at an angle parallel to the container's inner wall, creating a direct and efficient path for fresh water to enter the induction bowl, generating a rotating vortex for enhanced mixing and dissolution of active substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional nozzle arrangements are used in the induction bowl, then the structure is simpler to manufacture, but the flushing and mixing of active substances is less effective
Solution Approach 1:
The nozzle is divided into multiple functional components: a housing, a separately insertable nozzle element with the slit-shaped outlet opening, and a branch line connection. This segmentation allows for optimized flushing performance through the specialized nozzle geometry while keeping the overall structure modular and manufacturable.
Solution Approach 2:
The outlet opening is designed as a slit-shaped opening with a specific orientation angle relative to the induction bowl wall, introducing a directional component to the water flow. This angular orientation creates a more effective flushing pattern that improves mixing while maintaining a relatively simple nozzle structure.
2Reliability
If nozzles are arranged farther apart on the ring-shaped flushing line, then each nozzle has better access to the bowl interior, but the overall device size increases
Solution Approach 1:
The flushing line is designed as a ring-shaped structure that conforms to the curved interior surface of the induction bowl. This curved arrangement allows nozzles to be positioned at optimal intervals along the bowl's circumference, providing comprehensive coverage while maintaining a compact overall size that matches the bowl's volume.
Solution Approach 2:
Multiple nozzles are integrated into a continuous ring-shaped flushing line structure, combining several flushing functions into a unified system. This merging allows for compact arrangement of multiple nozzles around the bowl interior, achieving comprehensive coverage without increasing the bowl's overall volume.
3Productivity
If the outlet opening is oriented at an angle parallel to the container wall, then a rotating vortex is generated for better mixing, but the nozzle design becomes more complex
Solution Approach 1:
The outlet opening is designed with a specific angular parameter - oriented at an angle parallel to the container wall rather than perpendicular. This parameter change in the nozzle geometry directly generates the rotating vortex effect that enhances mixing efficiency, while the angular orientation itself is achieved through simple geometric design rather than complex mechanical components.
Solution Approach 2:
The angled orientation of the slit-shaped outlet opening causes the water stream to automatically generate a rotating vortex as it enters the induction bowl. The nozzle design utilizes the natural flow dynamics of the water stream itself to create the mixing effect, rather than requiring additional mechanical mixing components, thus achieving self-service mixing.

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 configuration results in improved flushing and mixing of active ingredients with fresh water, ensuring effective distribution and dissolution, enhancing the overall performance of the sprayer.
Implementation Method 1
the jet of fresh water emerging from the respective outlet openings of the induction nozzles is directed at an angle of 45° obliquely to the side and downwards towards the central area of the induction bowl. This arrangement is intended to produce a rotating and/or eddy-like movement of the liquid in the induction bowl

AI summary
Induction nozzle for a ring-shaped flushing line of an induction hopper of an agricultural field sprayer for the metered application of plant treatment products and/or fertilizers diluted with fresh water to form a spray solution, comprising a spray agent tank, a supply line connected to the flushing line with a fresh water supply device for supplying fresh water, wherein several induction nozzles spaced apart from each other, having at least partially downward-facing outlet openings, are arranged on the flushing line and the respective supply line of the respective induction nozzle is connected to the flushing line.In order to create compact induction nozzles and their compact arrangement on a flushing line arranged in the upper area and below the induction opening of an induction hopper and designed in an annular shape, it is provided that the outlet openings are slot-shaped and that the slot-shaped course of the outlet openings of the induction nozzles is aligned at least approximately parallel to the adjacent inner wall area of the induction hopper, that the line for supplying the fresh water is fed to the induction nozzle from above via a branch in the underside of the flushing line with a connecting branch line and is deflected in the area of the slot-shaped course of the outlet openings by at least approximately 90° towards the opposite wall of the slot of the outlet opening and opens via a discharge opening.
