And a coupling plate 161a is provided at the top of the particle storage bin 161 in the X-axis direction. The coupling plate 161a has a higher height in the Z-axis direction than the coupling plate described in FIG. 8. When mounting the particle dispersion unit 160, the coupling plate 161a is inserted into the coupling hole 151a, and its upper end protrudes toward the top of the reservoir support plate 151. The top of the coupling plate 161a is located on both sides of the pesticide storage container 152. The coupling plate 161a is in close contact with both sides of the pesticide storage tank 152 on both sides of the pesticide storage tank 152. The coupling plate 161a prevents the particle storage container 161 and the pesticide storage container 152 from shaking when the drone 10 flies, helping the drone 10 to fly stably.

Figure 15 is a diagram showing a cross section of a pesticide storage container according to an embodiment of the present invention.

Referring to FIG. 15, a first support rod 171, a second support rod 172, and a buoyancy plate 173 are provided inside the pesticide storage container 152.

The first support rod 171 is arranged in the Z-axis direction with its upper end coupled to the upper end of the pesticide storage bin 152, and its lower end coupled to the lower end of the pesticide storage bin 152.

The second support rod 172 is located a predetermined distance away from the first support rod 171 in the X-axis direction and is arranged in parallel with the first support rod 171. The upper end of the second support rod 172 is coupled to the upper end of the pesticide storage tank 152, and the lower end is coupled to the lower end of the pesticide storage tank 152.

The buoyancy plate 173 is a thin plate that can float on the water surface of the pesticide (B) by buoyancy. The buoyancy plate 173 has an area corresponding to the cross section of the pesticide storage container 152. A first hole (173a) and a second hole (173b) are formed in the buoyancy plate 173. The first support rod 171 is inserted into the first hole 173a, and the second support rod 172 is inserted into the second hole 173b.

When the pesticide storage tank 152 is filled with pesticide (B), the buoyancy plate 173 floats above the water surface of the pesticide (B) and is maintained in a horizontal state by the first support rod 171 and the second support rod 172. It can be maintained.

In the drone 10 according to the present invention, the pesticide storage container 152 and the particle storage container 161 are mounted together on one drone 10, and the upper end of the pesticide storage container 152 is located at the upper part of the electrical unit 110. Accordingly, the center of gravity is located relatively high compared to a drone provided with only one of the pesticide storage container 152 and the particle storage container 161. Therefore, during the flight of the drone 10, shaking may occur due to surrounding air currents, and this shaking causes the pesticide (B) to float and interfere with the stable flight of the drone 10. The buoyancy plate 173 is maintained in a horizontal state by the first support rod 171 and the second support rod 172, thereby preventing the pesticide B from sloshing around. Therefore, the drone 10 according to the present invention can fly stably even when shaking occurs.

Figure 16 shows the pesticide storage container separated from the drone, and Figure 17 shows the particle spraying part separated from the drone. In this way, the pesticide storage bin and particle spraying part can be separated from the drone and are easy to recombine.

Above, the present invention has been described in detail using preferred embodiments, but the scope of the present invention is not limited to the specific embodiments and should be interpreted in accordance with the appended claims. Additionally, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
