Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing spraying machines experience unevenness in the spraying amount of the spraying material due to tilting of the vehicle bodies when operating on sloped ground, leading to inconsistent application on plants.
Innovation Solution
A spraying machine with a support frame that includes a horizontal frame and vertical frames, allowing the spraying unit to be supported and maintained in a rotatable position around a fulcrum, ensuring consistent spraying across varying terrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the spraying machine operates on sloped ground with a fixed support frame, then the machine can maintain structural stability, but the spraying unit distance from plants varies causing uneven spraying amount
Solution Approach 1:
The support frame is designed to be rotatable around a rotation axis passing through the fulcrum portion, allowing the spraying unit to dynamically adjust its position in response to ground slope changes. This dynamic adjustment mechanism enables the spraying unit to maintain a consistent distance from plants even when the machine body tilts on sloped terrain, thereby ensuring uniform spraying application while preserving overall structural stability.
2Device complexity
If the spraying unit is fixed to the machine body, then the structure is simple and stable, but the spraying amount becomes uneven on slopes
Solution Approach 1:
The support frame connecting the spraying unit to the machine body is designed with rotational freedom around a fulcrum axis, transforming the fixed connection into a dynamic joint. This allows the spraying unit to automatically adjust its orientation and position relative to the machine body when the terrain slopes, maintaining consistent spraying distance without requiring complex active control systems or multiple adjustable components.
3Strength
If the support frame is made rigid and fixed, then the machine body remains stable, but the distance from spraying unit to plants varies on uneven terrain
Solution Approach 1:
The support frame maintains structural rigidity in its construction but introduces rotational degrees of freedom at the fulcrum connection point. This allows the frame to remain strong and stable while enabling the spraying unit to pivot and adjust its position automatically in response to ground slope variations, ensuring consistent spraying distance despite terrain unevenness.

AI summary
[Problem] To provide a spraying machine that can easily suppress occurrence of unevenness in the spraying amount of a spraying material. [Solution] A spraying machine 1 includes a machine body 10, a support frame 3, and a spraying portion 41. The support frame 3 includes a horizontal frame 3C having a length along a left-right direction D2, and a pair of vertical frames 3L and 3R each having a length along an up-down direction D1, and protruding downward from both ends of the horizontal frame 3C. The spraying portion 41 is supported by the support frame 3, and sprays a spraying material. The support frame 3 is supported by the machine body 10 to be rotatable around a rotation axis Axl passing through a fulcrum portion 31 provided on the horizontal frame 3C and extending along a front-back direction D3, while maintaining a relative positional relationship between the pair of vertical frames 3L and 3R, and the horizontal frame 3C.
