[0001] This solution belongs to the field of drone spraying devices, specifically involving a multi-functional drone spraying device for the prevention and control of grassland pests and diseases. Background Technology

[0002] A drone is an unmanned aerial vehicle that can be remotely controlled or fly autonomously. It relies on sensors, GPS, and communication systems to achieve stable flight and mission execution, and is widely used in aerial photography, agricultural plant protection, logistics transportation, surveying and mapping, rescue, and other fields, offering advantages such as high efficiency, flexibility, and adaptability to complex environments.

[0003] A search revealed a utility model patent application with publication number CN213768980U, which discloses a drone spraying device, relating to the field of drone plant protection technology. The device includes a mounting plate, a mixing tank, a support box, and a spray pipe. The mixing tank is located at the bottom of the mounting plate, and a support box is fixed to the lower part of the mixing tank. A filter box is fixed to the bottom of the support box, and the filter box is connected to the mixing tank via a pipeline. A solenoid valve is installed on the pipeline. A liquid outlet pipe is fixedly connected to the lower part of the support box, with its top end passing through the support box and communicating with the filter box, and its bottom middle end communicating with the spray pipe.

[0004] In existing technologies, traditional drone spraying devices have limitations in controlling pests and diseases in grasslands, including limited spraying range and fixed angles that cannot accurately adapt to plant morphology. Utility Model Content

[0005] The purpose of this solution is to provide a multi-functional drone spraying device for the prevention and control of grassland pests and diseases, in order to solve the problems of limited spraying range and fixed angle that cannot accurately adapt to plant morphology in existing drone spraying devices.

[0006] To achieve the above objectives, this solution provides a multi-functional drone spraying device for grassland pest and disease control, comprising a drone body, a support leg at the bottom of the drone body, an adjustment mechanism on the support leg, a rotating mechanism at the bottom of the drone body, the rotating mechanism including a water tank fixedly installed at the bottom of the drone body, a pump body at the bottom of the water tank, a first conduit fixedly installed at the outlet end of the pump body, and an inlet pipe of the pump body connected to the water tank, a vertical plate fixedly installed at the bottom of the drone body, a rotating rod rotatably connected to the vertical plate, a blade at one end of the rotating rod, and a gear fixed at the other end of the rotating rod, the adjustment mechanism including a hinge seat fixedly installed on the support leg, a housing rotatably connected to the hinge seat, and a first nozzle on the side of the housing.

[0007] The principle of this solution is as follows: Pesticide is added to the water tank, then the valve at the second conduit is opened, and a drone takes off. During flight, the drone rotates its blades, which in turn rotates a rotating rod. This rotating rod, through gears and a gear ring, drives the second conduit to rotate. The second conduit's rotation, in turn, drives the third conduit to rotate, which in turn drives the second nozzle in a circular motion. At this point, the pump is activated, and it delivers the pesticide from the water tank through the first and second conduits to the third conduit, where it is then sprayed out by the second nozzle. This setup facilitates a wider spraying range. When horizontal spraying is required, the valve at the fourth conduit can be opened, and the pump will... The pesticide is delivered to the container through the fourth conduit and sprayed out by the first nozzle on the surface of the container. This avoids the situation where the drone can only spray pesticides vertically. At the same time, an electric telescopic rod is installed, which can move a limit rod. When the limit rod moves, it will cause the container to deflect around the hinge seat through the frame, thereby adjusting the spraying angle of the first nozzle. Compared with the existing technology, when the drone moves, the wind will drive the second nozzle at the bottom of the third conduit to rotate, which will significantly expand the spraying range, improve the operation efficiency, and allow for flexible adjustment of the spraying angle, thereby achieving vertical and precise spraying of plants and significantly improving the functionality and operation effect of the drone spraying device.

[0008] The technical advantages of this solution are as follows: by setting up a rotating mechanism, when the drone moves, the wind will drive the second nozzle at the bottom of the third duct to rotate, thereby significantly expanding the spraying range and improving work efficiency. By setting up an adjustment mechanism, the spraying angle can be flexibly adjusted, thereby achieving vertical and precise spraying of plants, significantly improving the functionality and work effect of the drone spraying device.

[0009] Furthermore, a receiving plate is provided at the bottom of the water tank, and a second conduit is rotatably connected to the receiving plate. The first conduit is rotatably connected to the inner wall of the second conduit. The second conduit is provided for connection with the first conduit.

[0010] Furthermore, a toothed ring is fixedly installed on the second conduit, and the toothed ring meshes with a gear. By providing the gear and toothed ring, the second conduit is driven to rotate when the rotating rod rotates.

[0011] Furthermore, a valve is provided on the second conduit, and a third conduit is provided at the bottom end of the second conduit, with a second nozzle at the bottom end of the third conduit. The second nozzle is used for spraying pesticides.

[0012] Furthermore, an mounting plate is fixedly installed on the water tank, and an electric telescopic rod is provided on the mounting plate. A limit rod is installed at the telescopic end of the electric telescopic rod. The limit rod is used to allow sliding within the frame.

[0013] Furthermore, a frame is provided on the housing, and the limiting rod slides on the inner wall of the frame. The frame is provided to support the sliding of the limiting rod.

[0014] Furthermore, a fourth conduit is fixedly installed on the side of the first conduit, and a valve is provided on the fourth conduit.

By means of the rotating mechanism 2, when the drone moves, the second nozzle 24 at the bottom of the third conduit 210 will rotate due to wind power, thereby expanding the spraying range. The rotating mechanism 2 includes a water tank 25, which is fixedly installed at the bottom of the drone body 1 and is used to store pesticides. A pump body 26 is installed at the bottom of the water tank 25, with a first conduit 28 fixedly installed at the outlet end of the pump body 26. The inlet pipe of the pump body 26 connects to the water tank 25. A vertical plate 23 is fixedly installed at the bottom of the drone body 1 to support the rotation of the rotating rod 21. A rotating rod 21 is rotatably connected to the top of the water tank 25. One end of the rotating rod 21 is equipped with a blade 22, and the other end of the rotating rod 21 is fixed with a gear 27. A receiving plate 211 is provided at the bottom of the water tank 25. A second conduit 29 is rotatably connected to the receiving plate 211. A first conduit 28 is rotatably connected to the inner wall of the second conduit 29. The second conduit 29 is used to connect with the first conduit 28. A toothed ring 212 is fixedly installed on the second conduit 29. The toothed ring 212 meshes with the gear 27. The gear 27 and the toothed ring 212 are used to drive the second conduit 29 to rotate when the rotating rod 21 rotates. A valve is provided on the second conduit 29. A third conduit 210 is provided at the bottom of the second conduit 29. A second nozzle 24 is provided at the bottom of the third conduit 210. The second nozzle 24 is used to spray pesticides.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, an adjustment mechanism 3 is provided on the support leg 4. The adjustment mechanism 3 includes a hinge seat 32, which is fixedly installed on the support leg 4. The hinge seat 32 is used to support the installation of the housing 31. The housing 31 is rotatably connected to the hinge seat 32. A first nozzle 33 is provided on the side of the housing 31. An installation plate 34 is fixedly installed on the water tank 25. An electric telescopic rod 35 is provided on the installation plate 34. The electric telescopic rod 35 is used to drive the limit rod 38 to move linearly. The telescopic rod end of the electric telescopic rod 35... A limiting rod 38 is installed to slide within the frame 39. The frame 39 is provided on the box 31, and the limiting rod 38 slides on the inner wall of the frame 39. The frame 39 is provided to support the sliding of the limiting rod 38. A fourth conduit 36 ​​is fixedly installed on the side of the first conduit 28. A valve is provided on the fourth conduit 36, and one end of the fourth conduit 36 ​​is connected to the box 31. A bracket 37 is provided on the water tank 25 to limit the movement of the fourth conduit 36.

[0025] The specific implementation process of this utility model is as follows: Pesticide is added to the water tank 25, then the valve at the second conduit 29 is opened, and the drone is launched. During flight, the drone drives the blades 22 to rotate. The rotating blades 22, in turn, drive the rotating rod 21 to rotate. The rotating rod 21, through the gear 27 and gear ring 212, drives the second conduit 29 to rotate. The rotating second conduit 29, in turn, drives the third conduit 210 to rotate. The rotating third conduit 210, in turn, drives the second nozzle 24 to rotate. At this time, the pump body 26 is activated. The pump body 26 delivers the pesticide from the water tank 25 through the first conduit 28 and the second conduit 29 to the third conduit 210, and then sprays it out through the second nozzle 24. This setup facilitates a wider spraying range. When horizontal spraying of pesticides is required, the fourth valve can be opened. A valve at conduit 36 ​​and pump 26 deliver pesticides through the fourth conduit 36 ​​to the housing 31, where they are sprayed from the first nozzle 33 on the surface of the housing 31. This avoids the situation where the drone can only spray pesticides vertically. Simultaneously, an electric telescopic rod 35 is provided, which can move a limiting rod 38. When the limiting rod 38 moves, it causes the housing 31 to deflect around the hinge seat 32 via the frame 39, thereby adjusting the spraying angle of the first nozzle 33. Compared to existing technologies, when the drone moves, the wind will drive the second nozzle 24 at the bottom of the third conduit 210 to rotate, significantly expanding the spraying range, improving operational efficiency, and allowing for flexible adjustment of the spraying angle. This enables precise vertical spraying of plants, significantly enhancing the functionality and operational effectiveness of the drone spraying device.

[0026] This solution incorporates a rotating mechanism 2, which, when the drone moves, drives the second nozzle 24 at the bottom of the third conduit 210 to rotate, thereby significantly expanding the spraying range and improving operational efficiency. Furthermore, by incorporating an adjustment mechanism 3, the spraying angle can be flexibly adjusted, enabling precise vertical spraying of plants and significantly enhancing the functionality and operational effectiveness of the drone spraying device.
