Adjustable Z Support for Sprayer Boom Nozzle Height and Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lawn and garden spraying systems lack adjustability in nozzle height and angle, leading to suboptimal liquid application due to fixed nozzle positions, which can result in non-uniform coverage and waste, especially when dealing with liquids of varying viscosities or desired spray patterns.
Innovation Solution
A lawn/garden spraying device with an adjustable 'Z' support arrangement that allows for selective fixation of nozzle height and angle, featuring a linkage system with pivotable joints that can be locked into desired positions relative to the vehicle and target surface, enabling optimal nozzle placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the boom and nozzles are made fixed in position, then the device complexity is reduced, but the adaptability to different liquids and spray patterns deteriorates
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed boom structure into an adjustable one. The linkage system with pivot joints allows the boom to change its position and angle dynamically. Each linkage member can be pivoted to different angles and locked into place, enabling the nozzle height and angle to be adjusted according to different spraying requirements while maintaining structural simplicity through standardized linkage components.
2Measurement precision
If the linkage system includes multiple pivot joints for adjustment, then the adaptability and control precision are improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the adjustment system into multiple independent linkage members (lower linkage member, central linkage member, upper linkage member), each with its own pivot joint. This segmentation allows for precise control of nozzle position through sequential adjustment of each linkage segment, while keeping each individual linkage component relatively simple in design.
Solution Approach 2:
The linkage system uses multiple pivot joints that can be selectively locked at different angles, providing dynamic adjustability. Each pivot joint acts as an independent degree of freedom that can be adjusted and fixed, enabling precise control over nozzle height and angle without requiring a completely complex mechanical structure.

AI summary
In certain aspects the present disclosure provides lawn/garden spraying devices and methods for their use. The support arrangement is configured to be mounted to a trailer hitch of a lawn and garden tractor, ATV or UTV. The support enables the user to selectively fix the height and angle of the nozzles on a spray boom. The support forms an adjustable “Z” arrangement.
