Description

Technical Field

[0001] This utility model relates to the field of agricultural spraying equipment technology, and in particular to a drag chain spraying device for drones. 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] However, existing drone-based pesticide spraying devices have many limitations, mainly in the following two aspects:

[0004] First, the existing drone spray nozzles are designed directly below the multi-rotor. During operation, the high-speed rotating blades generate a spiral downward airflow field. At this time, the trajectory of the micron-sized droplets sprayed by the nozzle will inevitably be affected by the above airflow field, causing droplet drift and pesticide loss, resulting in poor spraying effect.

[0005] Secondly, flight altitude has a significant impact on the spraying effect of existing drones. If the flight altitude is too high, the droplet drift rate will increase, and the droplets may even evaporate before reaching the target. If the flight altitude is too low, the vertical distance between the drone and the crops will be small, and the airflow field generated by the multi-rotor will cause irreversible damage to the crops, such as lodging and broken branches, and will make the droplets more likely to drift. Utility Model Content

[0006] In view of this, the present invention provides a drag chain spraying device for drones, the main purpose of which is to provide a drag chain spraying device for drones that can adjust the distance between the nozzle and the crops as needed.

[0007] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0008] This utility model embodiment provides a drag chain spraying device for drones, the device comprising:

[0009] A drone component, comprising a drone body and a loading box, wherein the loading box is disposed on the upper part of the drone body;

[0010] The liquid supply component includes a liquid supply pipeline, a housing, an adapter, a roller, a motor, an output pipeline, and a nozzle. The housing is installed on the lower part of the UAV body. One end of the liquid supply pipeline is connected to the loading box, and the other end passes through the housing and is connected to the adapter. The output pipeline is wound around the outside of the roller. The motor is connected to the roller and is used to drive the roller to rotate around its axis. One end of the output pipeline is connected to the adapter, and the other end is connected to the nozzle.

[0011] Furthermore, the drone body includes a main platform, a support frame, and a rotor. The support frame is located at the lower part of the main platform, the rotor is located at the upper part of the main platform, and the loading box is detachably connected to the main platform.

[0012] Furthermore, the outer edge of the housing is fixedly connected to the bracket, one end of the housing has a first opening, the motor is detachably connected to the inner edge of the housing, the other end of the housing has a first through hole for the liquid supply pipeline to pass through, and the lower part of the housing is provided with a second through hole for the output pipeline to pass through.

[0013] Furthermore, the liquid supply component also includes a rotating shaft, one end of which is connected to the output end of the motor, and the other end is fixedly connected to the roller.

[0014] Furthermore, a bearing is provided at the other end edge of the roller, the outer edge of the bearing is connected to the edge of the first through hole, the inner edge of the bearing is connected to the roller, and the liquid supply pipeline passes through the bearing.

[0015] Furthermore, a third through hole is provided on the side of the roller, and one end of the output pipe is inserted into the third through hole and connected to the adapter.

[0016] Furthermore, the liquid supply component also includes a solenoid valve, which is disposed on the liquid supply pipeline.

[0017] Furthermore, the upper end of the nozzle is connected to the output pipeline, and multiple spray holes are provided on the outer peripheral side of the nozzle.

[0018] This utility model provides a drone-based drag chain spraying device. The drone component drives a liquid supply component. The drone component includes a drone body and a loading box, with the loading box positioned on the upper part of the drone body. The liquid supply component sprays fertilizer onto crops and includes a liquid supply pipe, a housing, an adapter, a roller, a motor, an output pipe, and a nozzle. The housing is installed on the lower part of the drone body. One end of the liquid supply pipe is connected to the loading box, and the other end passes through the housing and connects to the adapter. The output pipe... Outside the roller, the motor is connected to the roller to drive it to rotate around its axis. One end of the output pipe is connected to the adapter, and the other end is connected to the nozzle. Compared to existing technologies, the nozzles of existing drone spraying systems are designed directly below the multi-rotor. During operation, the high-speed rotating blades generate a spiraling downward airflow field. At this time, the trajectory of the micron-sized droplets sprayed by the nozzle is inevitably affected by the airflow field, causing droplet drift and pesticide loss, resulting in poor spraying effect. Flight altitude has a significant impact on the spraying effect of existing drones. Excessive altitude increases droplet drift, sometimes even causing droplets to evaporate before reaching the target. Insufficient flight altitude results in a small vertical distance between the drone and crops, leading to irreversible damage such as lodging and broken branches from the multi-rotor airflow, further contributing to droplet drift. This technical solution addresses this by installing a loading box at the top of the drone, containing the spray solution, and a supply unit at the bottom. The solution flows through a supply pipe, adapter, and output pipe into the nozzle. A motor controls a roller to rotate, causing the output pipe to extend out of the casing and move downwards, bringing the nozzle into contact with the drone. With a certain distance between the drone bodies, the nozzles spray the pesticide. On the one hand, the extended distance of the output pipeline can effectively spray the target crops, and on the other hand, the spraying position and height can be adjusted as needed. During flight, the drone body can adjust the distance between the nozzle and the crop according to the flight speed. The faster the flight speed, the larger the angle between the output pipeline and the ground, which can effectively avoid the influence of the airflow field generated by the drone body on the pesticide, so that the pesticide droplets are accurately sprayed onto the target crops, thereby effectively controlling the spraying distance and thus achieving the technical effect of improving the spraying efficiency of the pesticide droplets.

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

[0024] like Figures 1 to 4 As shown, this utility model embodiment provides a drag chain spraying device for drones, the device comprising:

[0025] The drone component includes a drone body and a loading box 12, wherein the loading box 12 is disposed on the upper part of the drone body;

[0026] The liquid supply component includes a liquid supply pipe 21, a housing 22, an adapter 23, a roller 24, a motor 25, an output pipe 26, and a nozzle 27. The housing 22 is installed on the lower part of the UAV body. One end of the liquid supply pipe 21 is connected to the loading box 12, and the other end passes through the housing 22 and is connected to the adapter 23. The output pipe 26 is wrapped around the outside of the roller 24. The motor 25 is connected to the roller 24 and is used to drive the roller 24 to rotate around its axis. One end of the output pipe 26 is connected to the adapter 23, and the other end is connected to the nozzle 27.

[0027] This utility model provides a drone-based drag chain spraying device. The drone component drives a liquid supply component. The drone component includes a drone body and a loading box 12, with the loading box 12 positioned on the upper part of the drone body. The liquid supply component sprays fertilizer onto crops and includes a liquid supply pipe 21, a housing 22, an adapter 23, a roller 24, a motor 25, an output pipe 26, and a nozzle 27. The housing 22 is installed on the lower part of the drone body. One end of the liquid supply pipe 21 is connected to the loading box 12, and the other end passes through the housing 22 and connects to the adapter 26. 3. The output pipe 26 is wound around the outside of the roller 24. The motor 25 is connected to the roller 24 to drive the roller 24 to rotate around its axis. One end of the output pipe 26 is connected to the adapter 23, and the other end is connected to the nozzle 27. Compared with the prior art, the nozzle 27 of the existing drone spraying is designed directly below the multi-rotor. During operation, the high-speed rotating blades generate a spiral downward airflow field. At this time, the trajectory of the micron-sized droplets sprayed by the nozzle 27 will inevitably be affected by the above-mentioned airflow field, causing droplet drift and liquid loss, resulting in poor spraying effect. Flight altitude affects the spraying effect of existing drones. The impact is significant. Excessive flight altitude increases droplet drift, sometimes even causing droplets to evaporate before reaching the target. Conversely, insufficient flight altitude results in a smaller vertical distance between the drone and crops, leading to irreversible damage such as lodging and broken branches from the multi-rotor airflow, further contributing to droplet drift. This technical solution addresses this by installing a loading box 12 on the upper part of the drone, containing the spraying solution. A liquid supply component is installed at the lower part of the drone. The solution flows through a supply pipe 21, an adapter 23, and an output pipe 26 into the nozzle 27. A motor 25 controls the rotation of the roller 24, causing the output pipe 26 to extend out of the housing 22 and downwards. The drone moves to create a certain distance between the nozzle 27 and the drone body. The nozzle 27 sprays the pesticide. On the one hand, the extended distance of the output pipe 26 can effectively spray the target crops. On the other hand, the spraying position and height can be adjusted as needed. During the flight of the drone body, the distance between the nozzle 27 and the crop can be adjusted according to the flight speed. The faster the flight speed, the larger the angle between the output pipe 26 and the ground, which can effectively avoid the influence of the airflow field generated by the drone body on the pesticide. This allows the pesticide droplets to be accurately sprayed onto the target crops, thereby effectively controlling the spraying distance and achieving the technical effect of improving the spraying efficiency of the pesticide droplets.

[0028] The aforementioned drone component functions to drive the liquid supply component. The drone component includes a drone body and a loading box 12. The loading box 12 is located on the upper part of the drone body. An existing drone body can be used. The drone body's load-bearing capacity must be sufficient to drive the loading box 12 and the liquid supply component. The loading box 12 is installed in the upper middle position of the drone body, and it must not interfere with the rotor rotation. The loading box 12 contains the required liquid solution. The liquid supply component functions to spray fertilizer onto crops. The liquid supply component includes a liquid supply pipe 21, a housing 22, an adapter 23, a roller 24, a motor 25, an output pipe 26, and a nozzle 27. The housing 24... 2. Installed on the lower part of the UAV body, one end of the liquid supply pipe 21 is connected to the loading box 12, and the other end passes through the housing 22 and is connected to the adapter 23. The output pipe 26 is wrapped around the outside of the roller 24. The motor 25 is connected to the roller 24 to drive the roller 24 to rotate around its axis. One end of the output pipe 26 is connected to the adapter 23, and the other end is connected to the nozzle 27. One end of the liquid supply pipe 21 is connected to the lower side of the loading box 12. A solenoid valve is installed on the liquid supply pipe 21, and personnel can control the opening or closing of the solenoid valve or the opening degree of the liquid supply pipe 21 via a remote control. The housing 22 is a rectangular housing 22. The housing 22 is fixed to the lower part of the UAV body by snap-fit ​​or welding. The motor 25 and roller 24 are installed inside the housing 22. The other end of the liquid supply pipe 21 is connected to the adapter 23. The function of the adapter 23 is to prevent liquid leakage when the roller 24 and the output pipe 26 rotate. Therefore, the adapter 23 is a universal joint. One end of the output pipe 26 is connected to the adapter 23, and the output pipe 26 is wound around the roller 24. When the roller 24 rotates around its axis under the drive of the motor 25, the output pipe 26 is released downward and extended. The nozzle 27 is installed at the other end of the output pipe 26. When spraying liquid, the rotation of the roller 24 causes the nozzle 27 to extend downward. As the drone moves further away from its main body, the distance between the nozzle 27 and the crops is controlled by adjusting the drone's flight altitude and the number of rotations of the roller 24. On one hand, the extended distance of the output pipe 26 can effectively spray the target crops, and the spraying position and height can be adjusted as needed. During flight, the distance between the nozzle 27 and the crops can be adjusted according to the flight speed. The faster the flight speed, the larger the angle between the output pipe 26 and the ground, which can effectively avoid the influence of the airflow field generated by the drone on the pesticide, allowing the pesticide droplets to be accurately sprayed onto the target crops. This effectively controls the spraying distance and thus improves the spraying efficiency of the pesticide droplets.

[0029] Furthermore, the drone body includes a main platform 111, a support 112, and a rotor 113. The support 112 is located at the lower part of the main platform 111, and the rotor 113 is located at the upper part of the main platform 111.

The main platform 111 adopts an existing drone control system, which can be operated by personnel via remote control, including controlling the start and stop of the rotor 113 and controlling the monitoring equipment on the main platform 111. The rotor 113 is installed at the upper part of the main platform 111 and can move the drone body by rotating. The support 112 is installed at the lower part of the main platform 111 and can provide a certain support capacity when the drone body lands. The shell 22 is installed between the two supports 112, thereby achieving the technical effect of protecting the liquid supply components.

[0030] Furthermore, the outer edge of the housing 22 is fixedly connected to the bracket 112, one end of the housing 22 has a first opening, the motor 25 is detachably connected to the inner edge of the housing 22, the other end of the housing 22 has a first through hole for passing through the liquid supply pipeline 21, and the lower part of the housing 22 is provided with a second through hole for passing through the output pipeline 26. In this embodiment, a housing 22 is further defined. One end of the housing 22 has a first opening. A motor 25 passes through the first opening and is installed inside the housing 22. The liquid supply component also includes a rotating shaft 28. One end of the rotating shaft 28 is connected to the output end of the motor 25, and the other end is fixedly connected to the roller 24. The motor 25 drives the roller 24 to rotate around its axis. A first through hole is provided at the other end of the housing 22. The other end of the liquid supply pipe 21 passes through the first through hole and is connected to an adapter 23. When the roller 24 rotates, the adapter 23 rotates, while the liquid supply pipe 21 does not rotate. A second through hole is provided on the side of the housing 22. When the roller 24 rotates, the other end of the output pipe 26 passes through the second through hole and extends downwards, thereby facilitating the extension of the supply pipe. Optionally, the output pipe 26 can be provided with a third through hole 29 on the side of the roller 24. One end of the output pipe 26 is inserted into the third through hole 29 and connected to the adapter 23. When the roller 24 rotates, it can drive the output pipe 26 to rotate around the axis of the roller 24, so that the output pipe 26 can be lowered or wrapped around the roller 24, thereby achieving the technical effect of conveniently lowering or retracting the output pipe 26. Optionally, the upper end of the nozzle 27 is connected to the output pipe 26. The outer peripheral side of the nozzle 27 is provided with multiple spray holes. The nozzle 27 adopts the existing liquid spray nozzle 27. The nozzle 27 is provided with multiple spray holes on its side. The spray holes can spray micron-sized droplets or mist droplets, thereby achieving the technical effect of uniformly spraying liquid.

[0031] Furthermore, a bearing is provided at the other end edge of the roller 24. The outer edge of the bearing is connected to the edge of the first through hole, and the inner edge of the bearing is connected to the roller 24. The liquid supply pipe 21 passes through the bearing. In this embodiment, the roller 24 is further defined, and a bearing is provided at the other end edge of the roller 24. When the roller 24 rotates, the inner ring of the bearing rotates, and the outer ring of the bearing is fixed at the edge of the first through hole.
