DETAILED DESCRIPTION

[0022] The possible implementation schemes that have been found in the art are:

[0023] At present, the technical advantages of plant protection drones include high efficiency and speed, precise application of pesticides, flexible applicability, environmental protection and energy saving; plant protection drones can plan flight paths according to the actual conditions of the farmland, adapt to different crop planting structures and terrain, and improve operational applicability; in addition, with the integration of cutting-edge technologies such as multispectral sensing technology, intelligent artificial applications, and high-precision navigation systems, plant protection drones can use image systems and collected farmland data to spray different areas on the planned path with different pesticides, allowing plant protection drones to achieve more efficient and precise plant protection operations.

[0024] The Chinese patent announcement number CN221699003U discloses a spraying medicine box for use with an unmanned helicopter, and specifically discloses that it includes a fuselage, a connecting column, a rotating blade and a support frame, one side surface of the fuselage is connected through the connecting column, one side surface of the connecting column is sleeved with a rotating blade, the lower surface of the fuselage is installed with a support frame, the upper surface of the fuselage is provided with a conversion mechanism, and the lower surface of the fuselage is provided with a mounting mechanism; the conversion mechanism includes a connecting frame, a double-layer bottom plate, a connecting pipe, a water pump, a solenoid valve, a spray nozzle and an atomizing nozzle, the lower surface of the fuselage is welded with a connecting frame, one side surface of the connecting frame is connected through the double-layer bottom plate, one side surface of the fuselage is connected through the connecting pipe, one side surface of the connecting pipe is fixedly connected to a water pump, one side surface of the water pump is connected to a solenoid valve, one side surface of the solenoid valve is fixedly connected to a spray nozzle, and one side surface of the solenoid valve is fixedly connected to an atomizing nozzle; the patent discloses a spraying medicine box for use with an unmanned helicopter, direct current and atomizing spray Switching technology allows farmers to adjust according to the needs of different crops. Some crops may be more suitable for direct current spraying, while others require atomized spraying. This flexibility helps to better meet the growth characteristics of different crops. Direct current spraying is suitable for precise application of pesticides to specific areas or plants to avoid unnecessary impact on the surrounding environment. Atomized spraying can cover a wider area and improve the coverage of spraying. Through flexible switching, the accuracy and coverage of spraying can be better balanced. Atomized spraying technology can atomize the liquid into tiny particles when spraying liquid, increase the uniform distribution of droplets, and improve the utilization rate of pesticides. In some cases, it can reduce the amount of pesticides used, reduce costs, and reduce the impact on the environment. Different farmland environments may require different spraying methods. By switching between direct current and atomized spraying, unmanned helicopters can better cope with diverse farmland conditions, including complex terrain, different vegetation heights, etc., and improve operational flexibility.

[0025] However, since the existing pesticide spraying device can only spray a single pesticide, when the plant protection drone needs to change the pesticide spraying, it is also necessary to replace the medicine box and spray the pesticide again in the required area. The plant protection drone cannot achieve the effect of spraying multiple pesticides in one operation. The plant protection drone needs to repeatedly fly multiple times in order to spray different pesticides, which makes the pesticide spraying efficiency low.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] Reference Figures 1-4 The utility model discloses a multi-medicine box pesticide spraying device suitable for a plant protection UAV, including a landing gear 4 detachably connected to the plant protection UAV, a main medicine box 1 for containing main pesticides fixedly connected to the landing gear 4, and a plurality of small medicine boxes 2 for containing other pesticides are detachably connected to the opposite outer walls of the main medicine box 1.

[0029] The utility model uses several detachable small medicine boxes 2, which not only facilitates the installation or disassembly of the small medicine boxes 2, but also enables each small medicine box 2 to be loaded with pesticides different from those in the main medicine box 1, and can spray different pesticides according to the disease conditions of field crops. That is, the mixing box 31 can be used to spray the pesticides in the main medicine box 1 or the small medicine box 2 alone, and the mixing box 31 can also be used to spray the pesticides in the main medicine box 1 and the small medicine box 2 together, and the effect of spraying multiple pesticides can be achieved in one operation, thereby effectively improving the efficiency of pesticide spraying.

[0030] In order to facilitate the installation or removal of the small medicine box 2, the main medicine box 1 can be used to install the small medicine box 2 on the main medicine box 1 through buckles.

[0031] In order to ensure that different pesticides are mixed evenly during the mixing and spraying process, an agitator is installed in the mixing box 31. The agitator allows the pesticides in the main medicine box 1 and the pesticides in the small medicine box 2 to be effectively mixed in the Hunhe line and sprayed through the nozzle 3.

[0032] In order to ensure that the liquid outlet pipe 32 is above the bracket at the bottom of the landing gear 4, a number of connecting blocks 15 are fixedly connected to the bottom surface of the main medicine box 1. The connecting blocks 15 are fixedly connected to the support rods at the bottom of the landing gear 4, so that the liquid inlet pipe 13 can be above the bracket at the bottom of the landing gear 4, and the bottom surface of the nozzle 3 is higher than the bottom surface of the landing gear 4.

[0033] A further optimization scheme features a liquid inlet pipe 13 fixedly connected to and connected to one side of the top surface of the main medicine box 1. The end of the liquid inlet pipe 13, remote from the main medicine box 1, extends through the pressure supply assembly and extends outside the assembly. An air inlet 14 is provided at the center of the top surface of the main medicine box 1 and communicates with the pressure supply assembly. Liquid inlet pipe 13 facilitates the loading of pesticides into the main medicine box 1. Air pressure from the pressure supply assembly enters the main medicine box 1 through air inlet 14, pressurizing the pesticide within the main medicine box 1 and dispensing it from the spray nozzle 3.

[0034] Further optimizing scheme, the bottom center of main medicine box 1 is provided with liquid outlet 17, and liquid outlet 17 is connected with medicine mixing box 31. Through liquid outlet 17, the pesticide in main medicine box 1 is convenient to enter medicine mixing box 31.

[0036] The first and second flexible joints 23 and 24 are threaded flexible joints, so that the first and second flexible joints 23 and 24 can be unscrewed or tightened. By installing or removing the first and second flexible joints 23 and 24, the installation or removal of the small medicine box 2 is facilitated.

[0037] In a further optimized solution, the pressure supply assembly includes a pressure dividing box 12 fixedly connected to the top surface of the main medicine box 1. The end of the pressure dividing box 12 facing away from the main medicine box 1 is fixedly connected and connected to the air pump 11. The air outlet of the air pump 11 is connected to the pressure dividing box 12 through the air inlet pipe 16. The air pressure provided by the air pump 11 enters the pressure dividing box 12 through the air inlet pipe 16.

[0038] As a further optimization, an air outlet is provided at the center of the bottom surface of the pressure dividing box 12, which is connected to the air inlet 14. The air pump 11 injects air pressure into the pressure dividing box 12, and the air pressure in the pressure dividing box 12 enters the main medicine box 1 through the air outlet and air inlet 14, and enters the small medicine box 2 through the air outlet pipe 24.

[0039] To further optimize the solution, one end of the liquid inlet pipe 13 extending out of the pressure dividing box 12 is threadedly connected to a sealing cover. The sealing cover effectively prevents the pesticide in the main medicine box 1 from spilling out through the liquid inlet pipe 13.

[0040] In a further optimization scheme, the end of the first flexible joint 23 away from the first aid kit 2 is fixedly connected to and communicates with an air outlet pipe 24, and the end of the air outlet pipe 24 away from the first flexible joint 23 is fixedly connected to and communicates with the pressure dividing box 12.

[0041] In a further optimized solution, the nozzle 3 extends out of the landing gear 4, and the bottom surface of the nozzle 3 is higher than the bottom surface of the landing gear 4. This prevents the nozzle 3 from contacting the ground and causing damage.

[0042] In order to facilitate the control of the spraying of pesticides in the main medicine box 1 and several small medicine boxes 2, a second electromagnetic valve is installed in the air outlet 24, a third electromagnetic valve is installed in the air inlet 14, and a fourth electromagnetic valve is installed in the liquid outlet 17; by opening and closing the first electromagnetic valve 22, the second electromagnetic valve, the third electromagnetic valve, and the fourth electromagnetic valve respectively, the pesticide in the main medicine box 1 can be sprayed separately, the pesticide in any small medicine box 2 can be sprayed separately, the pesticide in multiple small medicine boxes 2 can be sprayed mixedly, the pesticide in the main medicine box 1 and the pesticide in a single small medicine box 2 can be sprayed mixedly, and the pesticide in the main medicine box 1 and the pesticide in multiple small medicine boxes 2 can be sprayed mixedly.

[0043] The plant protection drone has intelligent control, image recognition, and computer analysis: by cooperating with the multi-box pesticide spraying device of the utility model, the plant protection drone can analyze farmland needs in real time and identify the types and distribution of crop diseases through the camera and image recognition system carried by the plant protection drone; the computer can automatically calculate the required pesticide types and concentrations based on the analysis results.

[0045] Pesticide loading: According to the formula generated by the computer, the prepared pesticides are loaded into the main medicine box and the small medicine box; the main medicine box 1 is loaded with the most required pesticides, and the small medicine box 2 can be flexibly loaded with other pesticides.

[0046] Self-selection: According to the actual disease situation and crop needs, you can actively choose to use several small medicine boxes 2 to achieve specific spraying for various diseases.

[0047] Working process:

[0048] During operation, cooperate with the plant protection drone and set the spraying parameters (such as the type of liquid medicine, concentration and spraying area) through the control panel of the plant protection drone; the computer control system automatically adjusts the opening and closing of the first electromagnetic valve 22, the second electromagnetic valve, the third electromagnetic valve and the fourth electromagnetic valve according to the set parameters to control the flow of the liquid medicine in different main medicine boxes 1 and small medicine boxes 2; the air pump 11 is started, and the compressed air pushes the liquid medicine in the main medicine box 1 to be sprayed out through the nozzle 3; the liquid medicine in the small medicine box 2 is also mixed as needed through the mixing box 31, and specific spraying is achieved through the nozzle 3.

[0049] By setting the path of the plant protection drone and setting the pesticides that need to be sprayed in each area, the main pesticides are injected into the main medicine box 1 through the liquid inlet pipe, and then the mechanical valve 21 on the small medicine box 2 is closed, and the required small medicine box 2 is installed in the main medicine box 1, and the small medicine box 2 is respectively connected to the pressure divider box 12 and the mixing medicine box 31, and then, other required pesticides are respectively injected into the small medicine box 2, and then the sealing covers are respectively tightened on the liquid inlet pipe 13 and the injection pipe on the small medicine box 2, and all the mechanical valves 21 on the small medicine box 2 installed on the main medicine box 1 are unscrewed, and then the landing gear 4 is installed on the plant protection drone. At this time, the plant protection drone can drive the landing gear 4 to fly according to the set path.

[0050] When the pesticide in the main medicine box 1 needs to be sprayed, the first solenoid valve 22 and the second solenoid valve are closed, the third solenoid valve and the fourth solenoid valve are opened, and the air pump 11 starts working. The air pressure provided by the air pump 11 enters the main medicine box 1, and the pesticide in the main medicine box 1 passes through the liquid outlet 17, the mixing box 31, the liquid outlet pipe 32 in turn, and is sprayed out from the nozzle 3.

[0051] When the pesticide in any small medicine box 2 needs to be sprayed, the third solenoid valve and the fourth solenoid valve are closed, and the first solenoid valve 22 and the second solenoid valve on the small medicine box 2 where the pesticide needs to be sprayed are opened.
