AI Technical Summary
Technical Problem
Existing sprayers face issues with uneven distribution of sprayed material due to vehicle tilting on inclined ground, affecting vertical plants.
Method used
A sprayer design with a support frame that includes a horizontal and pair of vertical frames, allowing the spraying unit to rotate about a front-to-rear axis, maintaining consistent distance to plants regardless of ground inclination.
Benefits of technology
The design effectively prevents uneven spraying by maintaining consistent material distribution across plants, even on uneven terrain.

Abstract
To provide a spraying machine easy to suppress occurrence of unevenness in an application amount of a spraying material.SOLUTION: A spraying machine 1 includes a machine body 10, a support frame 3 and a spraying part 41. The support frame 3 includes a transverse frame 3C having a length along a longitudinal direction D2, and a pair of longitudinal frames 3L, 3R having a length along a vertical direction D1, and projecting downward from both ends of the transverse frame 3C. The spraying part 41 is supported by the support frame 3, and sprays a spray material. While maintaining a relative physical relationship between the pair of longitudinal frames 3L, 3R and the transverse frame 3C, the support frame 3 is supported by the machine body 10, rotatably around an axial axis Ax1 along a cross direction D3, passing through a fulcrum part 31 provided on the transverse frame 3C.SELECTED DRAWING: Figure 9
