[0002] As modern agriculture gradually develops towards scientific planting, drones are increasingly used in crop planting. In terms of cost, time and expenses, the scientific use of drone atomization spraying devices to replace manual spraying can greatly reduce labor costs, not only saving water, but also increasing the utilization rate of pesticides to more than 30%;

[0003] When using the existing atomizing spraying device for drones to spray crops, the atomizer is generally installed below the propeller so that the pesticide can be evenly atomized and sprayed. However, considering that the pesticide liquid is prone to flight drift during the flight of the drone, if the distance between the atomizing nozzle and the crops is far, the pesticide liquid will more easily drift and evaporate, which will not only cause waste of pesticides and reduce the operation effect, but also reduce the effective utilization rate of the pesticide liquid. Therefore, a atomizing spraying device for drones is proposed to address the above problems. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 , the utility model provides a technical solution:

[0020] A kind of atomizing spray device for unmanned aerial vehicle comprises a main control compartment 1 for unmanned aerial vehicle, the bottom end position of the main control compartment 1 for unmanned aerial vehicle is fixedly connected with a water tank hanging top plate 2, and the four corner ends of the main control compartment 1 for unmanned aerial vehicle are respectively fixedly connected with oblique support rods 3, one side end of the oblique support rod 3 away from the main control compartment 1 for unmanned aerial vehicle is fixedly connected with a limiting sleeve 10, and the middle position of the bottom end of the limiting sleeve 10 is fixedly connected with a limiting sleeve 4, a spraying main pipe 5 is slidably connected with the middle and lower position of the inner side of the limiting sleeve 4, and the two sides of the spraying main pipe 5 are respectively fitted with vertical clamping rings 7 on the outside, a group of vertical clamping rings 7 are connected by a center chuck 11, a side support block 8 is fixedly connected to the lower position of one side of the vertical clamping ring 7, and one end of the side support block 8 is fixedly connected with a telescopic rod 9, a guide rod 12 is inserted in the middle position of the center chuck 11, and a spring 13 is sleeved on the outside of the guide rod 12.

[0021] like Figure 1As shown, a spray water tank 16 is fixedly installed at the bottom end of the water tank hanging top plate 2, and side brackets 17 are rotatably installed on both sides of the bottom end of the drone control main compartment 1, and the height of the side brackets 17 is greater than the height of the spray water tank 16. When the drone equipment stably lands on the ground and the spray water tank 16 is suspended and installed through the water tank hanging top plate 2, a group of side brackets 17 that are in stable contact with the ground will provide support from both sides of the bottom of the drone equipment to ensure that the entire water tank installation operation is stable.

[0022] like Figure 1 and Figure 2 As shown, a pressurized pipe 6 is connected to the middle position of one side of the spray pipe 5, and an atomizing nozzle 20 is connected to one end of the spray pipe 5. The atomizing nozzle 20 has a trumpet-shaped structure. When the entire UAV equipment realizes the spraying operation of crops in an atomized manner through the atomizing nozzle 20, the trumpet-shaped structure of the atomizing nozzle 20 can increase the range of the nozzle when spraying the liquid medicine; a driving motor 14 is fixedly installed at the middle position of the inner side of the limiting sleeve 10, and the output end of the driving motor 14 is fixedly installed. The propeller body 15 is fixedly connected to the drone, and there are two groups of propeller bodies 15. The propeller bodies 15 are arranged directly above the atomizing nozzle 20. When the entire drone equipment realizes stable flight above the crops through the high-speed rotation of the two groups of propeller bodies 15, since the propeller body 15 and the atomizing nozzle 20 below are arranged opposite to each other, after the atomizing nozzle 20 sprays the atomized liquid, the rotation of the propeller body 15 will bring a certain disturbance to the atomized liquid, making the spraying of the atomized liquid more uniform.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cylinder fixed end of the limiting sleeve 10 and the telescopic rod 9 is fixedly connected, the telescopic rod 9 is transmission connected through the side support block 8 and the vertical clamping ring 7, the vertical clamping ring 7 and the limiting sleeve 4 are coaxially arranged, the side support block 8 and the limiting sleeve 4 are slidingly connected, the upper and lower ends of the spring 13 are respectively fixedly connected to the limiting sleeve 4 and the center chuck 11, one side end of the limiting sleeve 10 is fixedly connected with an extension support rod 18, and the extension support rod 18 and the oblique support rod 3 are fixedly connected, and an infrared sensor 19 is fixedly installed at one side position of the bottom end of the extension support rod 18. When the telescopic rod 9 is pushed down to adjust the distance between the nozzle and the crop, the spring 13 connected to the limiting sleeve 4 through the center chuck 11 will be deformed and generate elastic potential energy, so that the subsequent limiting sleeve 4 can be subject to a certain elastic auxiliary limitation when realizing rebound reset.

[0024] Working process: The electric energy required for the device of the utility model when starting operation comes from the drone driving power supply module installed inside the drone control main compartment 1, and the output pipeline of the pressurized micro-water pump provided in the spray water tank 16 is connected to the four pressurized pipes 6 respectively. At the same time, the driving motor 14 and the TCRT5000 infrared sensor 19 are electrically connected to the drone controller provided in the drone control main compartment 1 through wiring, and the safe detection distance of the infrared sensor 19 is pre-set. When using the drone atomizing spraying device, first, the drone controller controls the multiple driving motors 14 to rotate respectively, so that it can achieve high-speed rotation with the corresponding propeller body 15, so that the entire drone equipment can achieve stable flight with the spraying structure provided at the bottom. At the same time, when the drone equipment flies into the crop planting area and needs to start the atomizing spraying operation. During operation, when the drone is in stable flight, the pressurized micro-water pump inside the spray water tank 16 gradually delivers the spray liquid into each spray main pipe 5 through the pressurized pipe 6. Under the rotation of the propeller, the atomized liquid sprayed from the atomizing nozzle 20 will be evenly spread and sprayed on the crops, cooperating with the entire drone equipment to complete the scientific spraying operation. During the flight of the drone equipment, when the infrared sensor 19 detects that the equipment flies to a position above crops with a lower growth height, the drone controller will simultaneously control multiple groups of telescopic rods 9 to push the side support block 8 downward, so that the vertical clamping ring 7 can pass through the center chuck 11 and the guide rod 12, and adjust the position of the spray main pipe 5 downward, so as to adapt and adjust the distance between the atomizing spray component and the crops, and avoid the atomizing spray component being too far away from the crops, which may cause the equipment to drift during the atomizing spraying process.

[0025] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
