Description

Technical Field

[0001] This utility model relates to the field of drone spraying equipment technology, and in particular to a foldable drone spraying system. Background Technology

[0002] In recent years, my country's low-altitude economy has rapidly developed, and drones, as an important component of this economy, have experienced explosive growth. Rotary-wing drones, in particular, have seen large-scale applications in multiple fields due to their flexibility, convenience, and efficiency, demonstrating a strong market growth trend. Rotary-wing drones are widely used in agricultural plant protection, significantly improving agricultural production efficiency and resource utilization through precise pesticide spraying and crop growth monitoring.

[0003] Existing agricultural drones mainly consist of the drone equipment, a pesticide tank, and a spraying device. The pesticide tank is installed on the upper part of the drone equipment, and the spraying device is installed on the lower part of the drone, below the rotor. When the drone is operating, the rotor rotates at high speed and generates a spiral downward airflow field. The droplets sprayed by the spraying device are affected by the airflow field, causing the droplets to drift and run off, thereby reducing the spraying effect. Furthermore, since the drone's flight altitude has a significant impact on the spraying effect, if the flight altitude is too high, the droplet drift rate will increase, causing the droplets to evaporate before they even contact the plant. When the flight altitude is too high, the airflow field generated by the rotor can cause irreparable damage to the plant. Utility Model Content

The pesticide tank is mounted on the upper part of the drone device, and the spraying device is mounted on the lower part of the drone, located below the rotor. When the drone is operating, the rotor rotates at high speed and generates a spiral downward airflow field. The droplets sprayed by the spraying device... The airflow field affects the spraying effect, causing droplets to drift and run off, thus reducing the spraying effect. Furthermore, the drone's flight altitude has a significant impact on the spraying effect; excessive flight altitude increases droplet drift, causing droplets to evaporate before contacting the plants.

During spraying, a supporting component drives a folding component and the nozzle component to extend towards the front of the drone, causing the nozzle component to extend away from the drone body. The folding component opens towards both ends of the supporting component, allowing the nozzle component to detach from the airflow field generated by the drone's rotor. This not only minimizes the impact of the airflow field generated by the drone's rotor on the sprayed pesticide but also allows for adjustment of the distance between the drone and the crops as needed, thereby improving spraying efficiency and effectiveness.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 6 As shown, this utility model embodiment provides a foldable drone spraying system, which includes:

[0025] The drone component includes a drone body and a liquid tank 12. The drone body includes a support platform 111 and a bracket 112. The liquid tank 12 is mounted on the support platform 111, and the bracket 112 is disposed at the lower part of the support platform 111.

[0026] The spraying component includes a pressurizing component 21, a supporting component 22, a folding component 23, and a nozzle component 24. The pressurizing component 21 is mounted on the bracket 112 and connected to the liquid tank 12. One end of the supporting component 22 is connected to the bracket 112, and the other end is connected to the folding component 23. The nozzle component 24 is mounted on both ends of the folding component 23, and the nozzle is connected to the liquid tank 12 through a connecting pipe.

[0027] This utility model proposes a foldable drone spraying system. The drone component is used to move the pesticide tank 12 and the spraying component. The drone component includes a drone body and a pesticide tank 12. The drone body includes a support platform 111 and a bracket 112. The pesticide tank 12 is mounted on the support platform 111, and the bracket 112 is located at the lower part of the support platform 111. The spraying component is used to spray crops. The spraying component includes a pressurizing component 21, a supporting component 22, a folding component 23, and a nozzle component 24. The pressurizing component 21 is mounted on the bracket 111. 2. The pressurizing component 21 is connected to the liquid tank 12. One end of the supporting component 22 is connected to the bracket 112, and the other end is connected to the folding component 23. The nozzle component 24 is installed at both ends of the folding component 23. The nozzle is connected to the liquid tank 12 through a connecting pipe. Compared with the prior art, the existing agricultural drone mainly includes a drone device, a liquid tank 12, and a spraying device. The liquid tank 12 is installed on the upper part of the drone device, and the spraying device is installed on the lower part of the drone and located below the rotor 113. When the drone is operating, the rotor 113 rotates at high speed and generates spiral downward airflow. The airflow field affects the spraying equipment, causing droplets to drift and run off, thus reducing the spraying effect. Furthermore, the drone's flight altitude has a significant impact on the spraying effect; excessive flight altitude increases droplet drift, causing droplets to evaporate before contacting the plants. At excessively high altitudes, the airflow generated by the rotor 113 can cause irreparable damage to the plants. In this technical solution, a liquid tank 12 is installed on the upper part of the drone body, and a spraying component is installed on the lower part. A pressurizing component 21 pressurizes the liquid tank 12, allowing the liquid in the tank to enter the nozzle through a connecting pipe. In component 24, during spraying, the support component 22 drives the folding component 23 and the nozzle component 24 to extend towards the front end of the drone body, causing the nozzle component 24 to extend away from the drone body. The folding component 23 opens towards both ends of the support component 22, allowing the nozzle component 24 to detach from the airflow field formed by the rotor 113 of the drone body. The nozzle component 24 sprays out the pesticide, which not only minimizes the impact of the airflow field generated by the drone rotor 113 on the pesticide sprayed by the nozzle component 24, but also allows for adjustment of the distance between the drone body and the crops as needed, thereby achieving the technical effect of improving spraying efficiency and spraying effect.

[0028] The aforementioned drone component functions to move the liquid tank 12 and the spraying component. The drone component includes a drone body and a liquid tank 12. The drone body includes a support platform 111 and a bracket 112. The liquid tank 12 is mounted on the support platform 111, and the bracket 112 is located at the lower part of the support platform 111. Existing drone equipment can be used for the drone body. A rotor 113 and the liquid tank 12 are mounted on the support platform 111. The bracket 112 is mounted at the lower part of the support platform 111. Typically, there are two brackets 112, which can support the takeoff and landing of the drone body. The liquid tank 12 contains the sprayed liquid. The spraying component... This device is used for spraying crops. The spraying component includes a pressurizing component 21, a supporting component 22, a folding component 23, and a nozzle component 24. The pressurizing component 21 is mounted on the bracket 112 and connected to the pesticide tank 12. One end of the supporting component 22 is connected to the bracket 112, and the other end is connected to the folding component 23. The nozzle component 24 is mounted at both ends of the folding component 23 and is connected to the pesticide tank 12 via a connecting pipe. The pressurizing component 21 uses an existing pressurizing pump and is mounted at the rear end of the bracket 112. The pressurizing component 21 is connected to the pesticide tank 12 via an air pipe, enabling it to spray pesticides onto crops. The liquid tank 12 is pressurized. A support component 22 is installed at the front end of the bracket 112, and the other end of the support component 22 extends away from the bracket 112. A folding component 23 is installed at the middle of the other end of the support component 22, allowing it to fold. Spray nozzle components 24 are installed at both ends of the folding component 23. The spray nozzle components 24 are connected to the liquid tank 12 via connecting pipes, allowing the liquid in the liquid tank 12 to enter the spray nozzle components 24 through the connecting pipes. The spray nozzle components 24 then spray the liquid. In this technical solution, the liquid tank 12 is installed on the upper part of the drone body, and a spraying component is installed on the lower part of the drone body. The pressurizing component 21 pressurizes the liquid tank 12, causing the liquid... The liquid pesticide in the tank 12 enters the nozzle component 24 through the connecting pipe. During the spraying operation, the support component 22 drives the folding component 23 and the nozzle component 24 to extend towards the front end of the drone body, so that the nozzle component 24 extends away from the drone body. The folding component 23 opens towards both ends of the support component 22, so that the nozzle component 24 is separated from the airflow field formed by the rotor 113 of the drone body. The nozzle component 24 sprays out the liquid pesticide, which can not only minimize the impact of the airflow field generated by the drone rotor 113 on the liquid pesticide sprayed by the nozzle component 24, but also adjust the distance between the drone body and the crops as needed, thereby achieving the technical effect of improving spraying efficiency and spraying effect.

[0029] Furthermore, the support component 22 includes a first support frame 221, a second support frame 222, a first hydraulic component, and a second hydraulic component. The first support frame 221 and the second support frame 222 are mounted on the bracket 112.

One end of the second hydraulic component is connected to the second support frame 222, and the other end is connected to the first hydraulic component. In this embodiment, a support component 22 is further defined. A first support frame 221 and a second support frame 222 are mounted on a bracket 112. The first support frame 221 is located above the second support frame 222. A first hydraulic component is mounted in the middle of the first support frame 221. Specifically, the first hydraulic component includes a first hydraulic pipe 223 and a first telescopic rod 224.

One end of the first telescopic rod 224 is inserted into the first hydraulic pipe 223, and the other end is connected to the folding component 23. The first hydraulic pipe 223 is filled with hydraulic oil, which can drive the first telescopic rod 224 to move toward or away from the first hydraulic pipe 223, so that the first telescopic rod 224 can extend or shorten. When the first telescopic rod 224 extends, the folding component 23 and the nozzle component 24 can move toward a direction away from the UAV body, thereby avoiding the airflow field generated by the rotor 113. The two ends of the second support frame 222 are mounted on the bracket 112. 2. The middle part of the second hydraulic component is connected to the second support frame 222. Specifically, the second hydraulic component includes a second hydraulic pipe 225, a second telescopic rod 226, and a second connector 227. The second connector 227 is installed at the lower part of the first hydraulic pipe 223. One end of the second hydraulic pipe 225 is connected to the middle part of the second support frame 222. One end of the second telescopic rod 226 is inserted into the second hydraulic pipe 225, and the other end is rotatably connected to the second connector 227. When the second telescopic rod 226 is shortened, the first hydraulic pipe 223 rotates downward, causing the folding component 23 and the nozzle component 24 to move downward. When the second telescopic rod 226 is extended, the first hydraulic pipe 223 rotates upward, causing the folding component 23 and the nozzle component 24 to move upward, thereby achieving the technical effect of conveniently adjusting the height of the nozzle component 24. Optionally, a hydraulic device is also provided on the UAV body. The hydraulic device is connected to the first hydraulic component and the second hydraulic component and is used to provide power to the first hydraulic component and the second hydraulic component.

[0030] Furthermore, the folding component 23 includes a connecting block 231, a first folding rod 232, a second folding rod 233, and a sliding component. The connecting block 231 is fixedly connected to the other end of the first telescopic rod 224. One end of the first folding rod 232 and the second folding rod 233 are rotatably connected to the connecting block 231, and the other end is equipped with the nozzle component 24. The sliding component is disposed on the first telescopic rod 224. In this embodiment, the folding component 23 is further defined. A connecting block 231 is fixed to the other end of the first telescopic rod 224. Connecting shafts are provided at both ends of the connecting block 231. The first folding rod 232 and the second folding rod 233 are rotatably connected to the connecting shafts of the connecting block 231, allowing the first folding rod 232 and the second folding rod 233 to rotate laterally around the axis of the connecting shaft. The sliding component includes a first sliding block 235, a second sliding block 236, a third sliding block 234, a first connecting rod 237, and a second connecting rod 238. The third sliding block 234 is slidably disposed on the first telescopic rod 224. The second sliding block 236 is slidably disposed on the first folding rod 232 and the second folding rod 233. The two ends of the first connecting rod 237 are rotatably connected to the first sliding block 235 and the third sliding block 234, respectively. The two ends of the second connecting rod 238 are rotatably connected to the second sliding block 236 and the third sliding block 234, respectively. The first sliding block 235 is fitted onto the first folding rod 232. Furthermore, the first sliding block 235 can slide or move on the first folding rod 232. Specifically, the first sliding block 235 has a first sliding hole through which the first folding rod 232 passes. The second sliding block 236 is fitted onto the second folding rod 233, and the second sliding block 236 can move or slide on the second folding rod 233. Specifically, the second sliding block 236 has a second sliding hole through which the second folding rod 233 passes. At the same time, the third sliding block 234 is fitted onto the first telescopic rod 224, allowing the third sliding block 234 to slide or move on the first telescopic rod 224. When it is necessary to retract the nozzle component 24, the third sliding block 234 is moved toward the drone body by manual or electric control. The first folding rod 232 and the second folding rod 233 rotate around the axis of the connecting shaft, causing the nozzle component 24 to move toward the drone body. Simultaneously, the first sliding block 235 and the second sliding block 236 move toward the nozzle component 24, thereby achieving the technical effect of conveniently folding the spraying component.

[0031] Furthermore, the nozzle component 24 includes an adjusting ring 241, a fixing screw 242, and a nozzle body 243. The adjusting ring 241 is installed at the other end of the first folding rod 232 and the second folding rod 233.

In this embodiment, the nozzle component 24 is further defined. The function of the adjusting ring 241 is to adjust the angle of the nozzle body 243. The adjusting ring 241 is installed at the other end of the first folding rod 232 or the second folding rod 233. The nozzle body 243 is installed on the side of the adjusting ring 241. The fixing screw 242 passes through the adjusting ring 241 and can abut against the side of the first folding rod 232 or the second folding rod 233. When it is necessary to fix the angle of the nozzle, tighten the fixing screw 242 so that one end of the fixing screw 242 abuts against the first folding rod 232 or the second folding rod 233 to fix the angle of the nozzle. A gyroscope can also be used with the nozzle to keep the nozzle always vertically downward.
