By carrying a special spraying device, the unmanned aerial vehicle can spray according to preset patterns or texts, creating beautiful farmland art works. Compared with the traditional manual spraying method, the unmanned aerial vehicle has higher operation efficiency. They can cover a large area of farmland in a short time and complete complex spraying tasks. This not only saves labor costs but also shortens the operation cycle.

Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figures 1-4, an unmanned aerial vehicle for spraying and painting on farmland, comprising: an unmanned aerial vehicle body 1, which is the core carrier of the entire farmland spraying and painting system. The unmanned aerial vehicle body 1 can perform high-altitude operations, covering a large area of farmland, improving operation efficiency, reducing labor costs, and at the same time avoiding the trampling or damage of crops; a feeding mechanism 3, installed on the unmanned aerial vehicle body 1, for storing and providing pigments. The feeding mechanism 3 includes a paint bucket 301 and a number of partitions 305. The paint bucket 301 is installed on the unmanned aerial vehicle body 1, and the number of partitions 305 are installed in the paint bucket 301, forming a linear array part for separating the space in the paint bucket 301. The paint bucket 301 can store multiple pigments simultaneously. The paint bucket 301 is used for storing and providing pigments to ensure the continuous supply of pigments during the spraying process. The large-capacity design meets the needs of long-term operations, reduces the frequency of refilling, and improves work efficiency. The partitions 305 achieve the partition storage of multi-color pigments, avoid pigment mixing, and facilitate the selection of different colors for spraying according to needs; a mixing mechanism 6, installed on the paint bucket 301, for continuously mixing the pigments in the mixing bucket. The mixing mechanism 6 includes: a plurality of stirring blades 602, arranged in the paint bucket 301, for mixing the paint; a power source 601, installed on the paint bucket 301, and the power shaft of the power source 601 is connected to the plurality of stirring blades 602. The power source 601 is used to provide rotational power for the stirring blades 602. The mixing mechanism 6 ensures that the pigments remain in a uniformly mixed state during storage and transportation, preventing pigment precipitation or stratification and affecting the spraying effect. The power source 601 uses a servo motor or can also use a stepping motor.

[0031] Refer to Figure 3 and Figure 4 , the feeding mechanism 3 further includes: a number of electromagnetic valves 304, installed on the paint bucket 301, for controlling the conveying switch of each type of paint; a plurality of filling ports 303, installed on the paint bucket 301, for adding paint into the paint bucket 301; a mounting seat 302, installed on the unmanned aerial vehicle body 1, and the paint bucket 301 is installed on the mounting seat 302. The electromagnetic valves 304 precisely control the conveying of each pigment, realizing precise color matching and spraying, and improving the painting accuracy.

[0032] Refer to Figure 2 and Figure 4 , a delivery pump 5, installed on the unmanned aerial vehicle body 1, and a number of electromagnetic valves 304 are all connected to the delivery pump 5; the delivery pump 5 includes: a feed pipe 502, one end of which is installed on the feed port of the delivery pump 5, and a number of electromagnetic valves 304 are all connected to the feed pipe 502; a discharge pipe 501, installed on the discharge port of the delivery pump 5.

[0033] Refer to Figure 1 and Figure 2, a delivery pipe 4 is installed on the paint bucket 301. The discharge pipe 501 is connected to the delivery pipe 4. The delivery pipe 4 is used to transport pigments. The delivery pipe 4 includes: a number of nozzles 401 installed on the delivery pipe 4, and the nozzles 401 are used to spray pigments.

[0034] Referring to Figure 1 and Figure 2 , a bracket 2 is installed on the UAV body 1. The paint bucket 301 is connected to the bracket 2, providing a stable installation platform for the paint bucket 301 and other related components, ensuring the stability and safety of the entire spraying system during flight. The bracket 2 is reasonably designed and can effectively reduce the load on the UAV body 1 and improve flight performance.

[0035] During use, the operator adds corresponding pigments into the paint bucket 301 through multiple filling ports 303 according to the requirements of farmland spraying and painting. Each pigment is separately added into different areas separated by the partition 305 to ensure that multiple pigments do not mix. The UAV body 1 is started and rises to the predetermined operating height. The power source 601 of the mixing mechanism 6 is activated, driving the stirring blades 602 to rotate in the paint bucket 301. The stirring blades 602 continuously mix the pigments to ensure that the pigments remain in a uniform state during storage and transportation, preventing pigment precipitation or stratification. According to the painting requirements, the operator selects the type of pigment to be sprayed through the control system, and the corresponding solenoid valve 304 is opened to allow the selected pigment to enter the delivery pump 5 through the feed pipe 502. The delivery pump 5 pumps the pigment out of the paint bucket 301 and transports it to the delivery pipe 4 through the discharge pipe 501. The pigment flows in the delivery pipe 4 and finally reaches the nozzles 401 installed on the delivery pipe 4. The nozzles 401 spray the pigment evenly and finely on the farmland. During spraying, the operator observes the spraying effect in real time through the monitoring equipment carried by the UAV and makes adjustments as needed to ensure that the spraying effect meets the expectations. If it is necessary to change the pigment or adjust the spraying mode, the operator can close the current solenoid valve 304 through the control system and open other solenoid valves 304 to achieve rapid pigment switching and adjustment of the spraying mode. When the farmland spraying and painting are completed, the UAV returns to the starting point or lands at a designated area. The operator turns off the power supplies of the UAV body 1, the mixing mechanism 6, the delivery pump 5 and other equipment, disconnects the connections of each component, and cleans and maintains components such as the paint bucket 301, the delivery pipe 4, and the nozzles 401 to ensure the performance and effect for the next use.

[0036] In summary, compared with the prior art, the following beneficial effects are achieved:

[0037] By arranging multiple partitions 305 inside the paint bucket 301, the partitioned storage of multi-color pigments is achieved. In cooperation with the solenoid valve 304 and the delivery pump 5 system, different colors can be directly switched during flight without the need to frequently recall the drone to the ground for manual paint replacement, improving the continuity of operation, reducing waiting and takeoff / landing time, and thus significantly enhancing the overall operation efficiency.

[0038] Through automated control, the operation process is simplified, manual intervention is reduced, the operation complexity and time cost are lowered, the wear and tear on the drone itself caused by frequent takeoffs and landings is reduced, the service life of the drone is extended, and the maintenance cost is further reduced.

[0039] Through the mixing mechanism 6, the uniform mixing state of the pigments during storage and delivery is ensured, preventing the influence of pigment precipitation or stratification on the spraying effect. By precisely controlling the opening and closing of the solenoid valve 304 and the flow rate of the delivery pump 5, the precise proportioning and delivery of the pigments can be achieved, improving the spraying accuracy and effect.

[0040] Through the partitioned storage and rapid switching of multi-color pigments, the needs of different farmland spraying and painting can be flexibly adapted. Whether it is a simple pattern or a complex color combination, it can be achieved by adjusting the solenoid valve 304 and the spraying parameters, improving the flexibility and adaptability of the system.
