[0035] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0036] Unmanned aerial vehicles (UAVs) are widely used in agriculture. These UAVs can be equipped with various operating systems, enabling agricultural spraying and sowing operations. Currently, when using UAVs for spraying, the spraying devices follow the movement of the UAV to achieve the spraying operation, thus enabling rapid, large-area, and high-volume spraying.

[0037] Centrifugal nozzles are commonly used spraying equipment in agricultural spraying. They use a rotating spray disc to propel liquid outwards at a 360° angle. However, existing spraying devices suffer from the technical problem of not being able to adjust the spray angle.

[0038] Please refer to Figures 1-4 This embodiment provides a plant protection device, which includes a plant protection carrier and a centrifugal sprayer mounted on the plant protection carrier. The centrifugal sprayer can follow the movement of the plant protection carrier to perform spraying operations. This plant protection device can effectively improve the aforementioned technical problems, and can adjust the spraying angle to adjust the spraying area, making it more flexible and efficient to use.

[0039] In this embodiment, the plant protection carrier is an unmanned vehicle (UAV). Specifically, it is an agricultural mobile UAV. The centrifugal spraying equipment can be mounted on the UAV and follow its movement to perform spraying operations. In other embodiments, the plant protection carrier can also be a drone, specifically an agricultural drone, which generally carries spraying components, seeding components, etc., required for agriculture, enabling spraying irrigation, sowing, etc. Of course, the plant protection carrier can also carry cameras, gaming devices, etc. Furthermore, the carrier is not limited to UAVs or drones; for example, the plant protection carrier can also be a robot, an unmanned boat, etc.

[0040] Please refer to Figures 1-4 The centrifugal spraying equipment includes a liquid storage tank and a centrifugal spraying device 100. The liquid storage tank and the centrifugal spraying device 100 are connected. The liquid in the liquid storage tank can be transported to the centrifugal spraying device 100 and sprayed outward through the centrifugal spraying device 100 to realize the spraying operation.

[0041] In this embodiment, the centrifugal spray device 100 includes a centrifugal nozzle 10, a return member 20, and a guide member 30. The centrifugal nozzle 10 is used to spray droplets and includes a power motor and a centrifugal spray disk 11. The power motor and the centrifugal spray disk 11 are connected. The return member 20 covers part of the edge of the centrifugal nozzle 10 and is used to collect the returned droplets during the spraying process of the centrifugal spray disk 11. The guide member 30 is movably connected to the return member 20 and covers part of the edge of the centrifugal nozzle 10. The guide member 30 is used to move relative to the centrifugal spray disk 11 to adjust the range of the guide member 30 covering the edge of the centrifugal nozzle 10, thereby adjusting the spraying angle of the centrifugal nozzle 10.

[0042] Specifically, the centrifugal nozzle 10 typically achieves spraying by rotation, enabling 360° spraying over a wider area and at more angles. However, in situations requiring directional spraying, the spray angle of the centrifugal nozzle 10 cannot be adjusted, making it unsuitable for different spraying scenarios. To address this technical problem, the centrifugal spray device 100 provided in this embodiment allows the guide member 30 to move relative to the centrifugal spray disk 11 during use. This adjusts the area covered by the guide member 30 around the edge of the centrifugal nozzle 10, thereby adjusting the spray angle of the centrifugal nozzle 10 to achieve directional spraying. This centrifugal spray device 100 allows for adjustment of the spray angle, thus adjusting the spray area and making it more flexible and efficient. Simultaneously, the return member 20 covers part of the edge of the centrifugal nozzle 10, allowing some droplets from the centrifugal nozzle 10 to flow back into the return member 20 for recycling during the spraying process.

[0043] In this embodiment, the liquid storage tank is connected to both the return component 20 and the centrifugal nozzle 10. The liquid in the liquid storage tank enters the centrifugal nozzle 10 and is sprayed outward through the centrifugal nozzle 10. During the spraying process, the return component 20 can recover the droplets and concentrate the collected droplets in the liquid storage tank for reuse.

[0044] It should be noted that the guide member 30 includes a guide cover 31 and a connector 32. The connector 32 is connected to the guide cover 31. The guide cover 31 is rotatably connected to the return member 20 through the connector 32. The guide cover 31 covers part of the edge of the centrifugal nozzle 10. The guide cover 31 rotates relative to the return member 20 about the axis of the connector 32.

[0045] Specifically, the guide element 30 is made of a soft material or an accordion-style folding cover.

[0046] In this embodiment, the guide cover 31 has a semi-enclosed arc-shaped structure. The guide cover 31 includes an integrally formed first cover and a second cover, which have the same shape and together form a guide space. A portion of the edge of the centrifugal nozzle 10 is located within this guide space. When the centrifugal nozzle 10 is spraying, droplets sprayed from the edge within the guide space are blocked by the first and second covers, preventing them from being sprayed out and thus reducing the spray angle of the centrifugal nozzle 10. Of course, the blocked droplets can enter the return member 20 for reflux collection under the action of centrifugal force.

[0047] It should also be noted that the connector 32 is a swivel buckle structure. The connector 32 includes a protrusion and a groove. The groove contains multiple protruding teeth, and the protrusion has corresponding mating grooves. The protrusion is fitted into the groove, and the protruding teeth and mating grooves correspond one-to-one. The guide cover 31 and the return component 20 are rotatably connected through the protrusion and the groove. Rotating the guide cover 31 causes the protrusion to rotate within the groove, and the protruding teeth move and engage within different mating grooves, thereby achieving rotation and adjusting the relative position between the guide cover 31 and the return component 20.

[0048] Understandably, the guide cover 31 can rotate relative to the return member 20 about the central axis of the protrusion.

[0049] In this embodiment, the rotation angle of the guide cover 31 is between 0° and 135°. Specifically, the maximum rotation angle of the guide cover 31 is 135°. In other embodiments, the maximum rotation angle of the guide cover 31 can be 130°, 125°, or 120°. No specific limitation is made here.

[0050] In use, the centrifugal spray disk 11 has its maximum spray angle when the guide cover 31 is completely in contact with the outer wall of the return member 20, and its minimum spray angle when the guide cover 31 is rotated to its maximum position away from the return member 20. By adjusting the extent to which the guide cover 31 covers the edge of the centrifugal spray disk 11, the spray angle of the centrifugal spray disk 11 can be adjusted, thereby achieving the purpose of directional spraying. Specifically, the return member 20 covers at least half of the edge of the centrifugal spray disk 11.

[0051] In this embodiment, the return element 20 covers half of the edge of the centrifugal spray disk 11. The straight line of the return element 20 near the end face of the centrifugal spray disk 11 overlaps with the straight line of the axis point of the centrifugal spray disk 11.

[0052] It should also be noted that the return component 20 includes an upper return shroud 21 and a lower return shroud 22 that are detachably connected to each other. The upper return shroud 21 and the lower return shroud 22 together form a return channel, which is connected to the centrifugal nozzle 10. Some of the droplets from the centrifugal nozzle 10 during the spraying process are recovered through the return channel.

[0053] Specifically, the upper reflux hood 21 and the lower reflux hood 22 are detachably connected by bolts. The inlet of the reflux channel is connected to the edge of the centrifugal spray disc 11, and the outlet of the reflux channel is connected to the storage tank. The length of the inlet of the reflux channel is greater than the diameter of the centrifugal spray disc 11, and the length of the inlet of the reflux channel is greater than the length of the outlet of the reflux channel. During the spraying process, when the centrifugal spray disc 11 rotates to the inlet of the reflux channel, the droplets are blocked by the upper reflux hood 21 and the lower reflux hood 22. The temperature of the droplets gradually decreases, forming liquid, which then flows towards the outlet of the reflux channel under the action of centrifugal force, eventually entering the storage tank for collection.

[0054] More specifically, the ends of the upper reflux shroud 21 and the lower reflux shroud 22 away from the guide shroud 31 are connected to connectors 60, which communicate with the liquid storage tank. Specifically, connector 60 is a pagoda-shaped outlet.

[0055] It should also be noted that the return component 20 also includes a return filter 50, which is located at the end of the return channel near the liquid storage tank and can filter the liquid.

[0056] In this embodiment, to prevent droplets from liquefying when they reach the ends of the upper and lower return hoods 21 and 22 near the guide hood during spraying, both the upper and lower return hoods 21 and 22 near the guide member 30 are provided with chamfers 40. The straight line containing the chamfer 40 is parallel to the droplet ejection path, thereby reducing the contact area between the droplets and the upper and lower return hoods 21 and 22 during spraying, thus preventing the formation of water droplets. This further prevents water droplets from falling onto the centrifugal spray disc 11, which would reduce the lifespan of the centrifugal spray disc 11.

[0057] The centrifugal spraying device 100, centrifugal spraying equipment, and plant protection equipment provided in this embodiment have at least the following advantages:

[0058] In existing technologies, centrifugal nozzles 10 typically achieve spraying by rotation. During rotation, the centrifugal nozzle 10 can achieve 360° spraying, resulting in a wider spray area and more angles. However, in situations requiring directional spraying, the spray angle of the centrifugal nozzle 10 cannot be adjusted, making it unsuitable for different spraying scenarios. To address this technical problem, the centrifugal spray device 100 provided in this embodiment allows the guide member 30 to move relative to the centrifugal spray disk 11 during use. This adjusts the area covered by the guide member 30 around the edge of the centrifugal nozzle 10, thereby adjusting the spray angle of the centrifugal nozzle 10 to achieve directional spraying. This centrifugal spray device 100 can adjust the spray angle, thus adjusting the spray area, making it more flexible and efficient. Simultaneously, the return member 20 covers part of the edge of the centrifugal nozzle 10, allowing some droplets from the centrifugal nozzle 10 to flow back into the return member 20 for recycling during the spraying process.

[0059] In summary, this invention provides a centrifugal spraying device 100, a centrifugal spraying equipment, and a plant protection device. The centrifugal spraying device 100 includes a centrifugal nozzle 10 and a guide member 30. The centrifugal nozzle 10 is used to spray droplets and includes a power motor and a centrifugal spray disk 11, which are connected. The guide member 30 covers a portion of the edge of the centrifugal nozzle 10 and is movable relative to the centrifugal spray disk 11 to adjust the range of the guide member 30 covering the edge of the centrifugal spray disk 11. When in use, the centrifugal nozzle 10 sprays droplets while rotating. The guide member 30 covers a portion of the edge of the centrifugal nozzle 10 and is movable relative to the centrifugal spray disk 11, thereby adjusting the range of the guide member 30 covering the edge of the centrifugal nozzle 10, and thus adjusting the spraying angle of the centrifugal nozzle 10 to achieve directional spraying. This centrifugal spraying device 100 can adjust the spraying angle, thereby adjusting the spraying area, making it more flexible and efficient.

[0060] This centrifugal spraying equipment includes a liquid storage tank and a centrifugal spraying device 100. The liquid storage tank is also connected to a centrifugal nozzle 10 and a return component 20. During use, this centrifugal spraying equipment allows for adjustment of the spray angle, thereby adjusting the spray area and achieving directional spraying, making it more flexible and efficient.

[0061] This plant protection equipment includes a plant protection carrier and a centrifugal sprayer, with the centrifugal sprayer mounted on the plant protection carrier. During use, the centrifugal sprayer can be mounted on the plant protection carrier and follow its movement to perform spraying operations, enabling large-area, multi-angle spraying. This makes it more flexible and convenient to use, improving spraying efficiency and overall work efficiency.
