Rotatable Support Frame for Uniform Spraying on Inclined Ground
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing work machines, unevenness in the work amount occurs due to vehicle body tilting on inclined ground, affecting the distribution of chemicals or materials being sprayed, particularly for plants with vertical growth.
Innovation Solution
A work machine design featuring a support frame rotatable around a front-back axis to maintain a consistent attitude, supported by a machine body, and equipped with an antenna for positioning, which helps in stabilizing the spraying unit and ensuring uniform coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the work machine operates on inclined ground with a fixed vehicle body structure, then the machine can maintain structural simplicity, but the vehicle body tilts causing uneven chemical distribution on plants
Solution Approach 1:
The patent applies the dynamics principle by making the support frame rotatable relative to the vehicle body around a rotation axis. This dynamic structure allows the support frame to maintain a consistent attitude (horizontal orientation) while the vehicle body tilts on inclined ground, thereby keeping the work unit positioned correctly over the plants and ensuring uniform chemical distribution without requiring a complex fixed inclination compensation mechanism
2Strength
If the support frame is fixed to the vehicle body, then the structure is simple and robust, but the work unit cannot maintain consistent attitude on inclined surfaces
Solution Approach 1:
The support frame is designed to be rotatable relative to the vehicle body, creating a dynamic connection that allows the frame to adjust its orientation independently. This rotational degree of freedom enables the support frame to maintain a consistent horizontal attitude while the vehicle body tilts, preserving both structural robustness through the rigid frame design and attitude consistency through its ability to rotate and adapt to ground inclination
Solution Approach 2:
The patent segments the machine into distinct functional modules: the vehicle body, the rotatable support frame, and the work unit. This segmentation allows the support frame to be independently rotatable relative to the vehicle body, enabling the frame to maintain consistent attitude on inclined surfaces while the vehicle body adapts to ground conditions, thus achieving both structural robustness and spraying attitude consistency
