Abstract
Description
Technical Field
[0001] This invention relates to the field of drone technology, and more particularly to a drone equipped with a material spraying device. Background Technology
[0002] With the rapid development of agricultural mechanization and intelligentization, drones, due to their flexible and mobile operational characteristics, have been widely used in the field of pesticide spraying in farmland. Compared with traditional manual backpack spraying or ground-based mechanical spraying methods, drones can overcome terrain limitations, quickly cover large areas of farmland, and significantly reduce the intensity of manual labor and operational risks. At the same time, drones can reduce pesticide drift in non-target areas by precisely controlling flight altitude, speed, and spraying path, thereby improving pesticide utilization efficiency. This is of great significance for ensuring the ecological environment of farmland and the safety of crop growth, and is especially suitable for efficient plant protection operations in large-scale planting bases.
[0003] However, existing drone pesticide spraying technology still has the following limitations in practical applications: some drones need to be refilled one by one after the pesticides in the water tank have been sprayed, and the frequent start-stop refilling process causes operation interruption and wastes a lot of time; other drones use a one-time quantitative preparation of liquid pesticide spraying solution, but liquid pesticides are prone to precipitation during storage and transportation. Since pesticides include not only liquid pesticides but also solid powder pesticides, if they are not thoroughly stirred or stored for a long time, precipitation is very likely to occur, which not only affects the efficacy but may also clog the atomizing nozzle, increase the risk of equipment failure and crop burns. Moreover, the use of quantitatively prepared liquid pesticide spraying solution in large quantities will also increase transportation costs, and the convenience of using drones for operation is not high.

Compared with the method of mixing pesticides in the water tank after each spraying by the drone body, this saves preparation time.

[0018] 3. The atomizing mechanism sprays the diluted pesticide solution in a spiral shape, which is then mixed and diluted with water atomized droplets. The atomized water droplets are sprayed in both upward and downward directions, resulting in a two-stage fusion and dilution of the pesticide solution droplets and water atomized droplets.

[0029] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0030] like Figures 1-8As shown, this embodiment proposes a drone with a material spraying device, including a drone body 1. A mixing mechanism 2 and a dilution mechanism 3 are fixedly connected inside the drone body 1, and the mixing mechanism 2 and the dilution mechanism 3 are connected through a second conduit 6. An atomizing mechanism 5 is fixedly connected to the lower end of the drone body 1, and the dilution mechanism 3 and the atomizing mechanism 5 are connected through a first conduit 4. The mixing mechanism 2 includes a mounting base 21, a storage tank 28, and a mixing chamber 211. Conveying rollers 212 are rotatably connected to both sides of the mixing chamber 211, and drive gears 21 are fixedly connected to the rear ends of the conveying rollers 212. 3. A rotating shaft 26 is rotatably connected to the lower inner part of the medicine storage box 28. An auger 27 is fixedly connected to the outer periphery of the rotating shaft 26. A conveying pipe 214 is fixedly connected to the lower end of the medicine storage box 28 near the mounting base 21. A servo motor 22 and a bevel gear 29 are fixedly connected to the upper end of the mounting base 21. A pulley 23 is fixedly connected to the lower drive end of the servo motor 22. The pulley 23 is connected to the pulley 3 25 through a transmission belt 24. A bevel gear 210 is meshed with the bevel gear 29. The rear end of the bevel gear 210 is fixedly connected to the rear end of the right drive gear 213.
[0031] In this embodiment, the lower ends of the mounting base 21 and the mixing chamber 211 are both fixedly connected to the middle of the inner bottom wall of the drone body 1, the lower middle outer periphery of the medicine storage box 28 is fixedly connected to the openings on both sides of the upper middle part of the drone body 1, and the end of the conveying pipe 214 near the mounting base 21 is fixedly connected to the openings on both sides of the rear end of the mixing chamber 211.
[0032] It should be noted that the main body of the drone 1 is mainly composed of the fuselage, wings, brushless motor, propeller and landing gear. The fuselage contains the control system, battery wireless signal transceiver and supporting circuits. As for how to achieve the take-off, landing, ascent and descent and turning of the main body of the drone 1, and how to achieve remote control, these are all existing technologies and are mature, so they will not be elaborated again.
[0033] Specifically, all pesticides are mixed with water in a certain proportion to form a paste and stored. The end cap at the top of the pesticide storage tank 28 is opened, and the mixed pesticide is added to the storage tank 28. Clean water is added to the water tank 51. The main body of the drone 1 is started and flies over the farmland. The servo motor 22 drives the pulley 25 and pulley 39 to rotate through the pulley 23 and the transmission belt 24. The stirring rod 32 drives the impeller 311 to rotate, thereby drawing clean water from the inside of the water tank 51 through the conduit 7 312 and the check valve at the bottom. A small portion of the clean water is sent into the mixing chamber 211 through the three-way flow control valve 313 and the conduit 4 315. At the same time, the pulleys 25 on both sides drive the auger 27 to rotate inside the storage tank 28 through the rotating shaft 26, thus distributing the paste-like pesticide through the conduit 26. The feed pipe 214 pumps the pesticide into the mixing chamber 211, where it mixes with clean water. The servo motor 22 drives the bevel gear 29 and bevel gear 210 to rotate, which in turn drives the pesticide mixed with water inside the mixing chamber 211 through the drive gear 213 on both sides to be delivered to the dilution chamber 31 via the conduit 26. Through the cooperation of the mixing mechanism 2 and the dilution mechanism 3, all pesticides can be mixed into a paste at once according to the actual usage. Compared with the method of preparing the pesticide after each spraying of the pesticide in the clean water chamber 51 by the main body of the drone, the preparation time is saved. Compared with the method of preparing the pesticide spray solution in a one-time quantitative manner, the paste-like pesticide is less likely to precipitate, which is more conducive to the convenience and safety of spraying pesticides on farmland using the main body of the drone 1 and the atomizing mechanism 5.
[0034] In this embodiment, the dilution mechanism 3 includes a dilution chamber 31 and a liquid extraction chamber 310. A heater 316 is fixedly connected to the inner center of the dilution chamber 31. A filter screen 317 is fixedly connected to the upper inner part of the dilution chamber 31. A funnel 318 is fixedly connected to the opening in the middle of the front side of the filter screen 317. A rotating seat 34 is rotatably connected to the lower inner part of the dilution chamber 31. A stirring rod 32 is rotatably connected inside the rotating seat 34. Two sets of stirring blades 33 are distributed in the upper middle part of the stirring rod 32. A dispersing blade 35 is fixedly connected to the outer periphery of the rotating seat 34. A geared disc 36 is fixedly connected to the lower end of the rotating seat 34. A transmission gear 37 is meshed with the geared disc 36. A geared disc 38 is meshed with the transmission gear 37. A pulley 39 is fixedly connected to the lower end of the stirring rod 32.
[0035] In this embodiment, the front end of the mixing chamber 211 is connected to the rear end of the second conduit 6. The front end of the second conduit 6 is fixedly connected to the lower rear middle of the dilution chamber 31. The outer periphery of the dilution chamber 31 is fixedly connected to the upper middle front opening of the drone body 1. The first pulley 39 is connected to the second pulley 23 through the transmission belt 24. The lower end of the second gear 38 is fixedly connected to the upper end of the first pulley 39. The middle part of the transmission gear 37 is rotatably connected to the right middle part of the gear seat 319.
[0036] In this embodiment, an impeller 311 is rotatably connected inside the liquid extraction chamber 310. A conduit 312 is fixedly connected inside the lower middle opening of the liquid extraction chamber 310. A three-way flow control valve 313 is fixedly connected to the left outlet end of the liquid extraction chamber 310. A conduit 315 is fixedly connected inside the upper opening of the three-way flow control valve 313. A conduit 314 is fixedly connected inside the left opening of the three-way flow control valve 313. The upper end of the conduit 314 is fixedly connected to the lower opening at the left rear end of the dilution chamber 31.
[0037] In this embodiment, the lower end of the stirring rod 32 is fixedly connected to the upper end of the impeller 311, the lower end of the conduit 312 is fixedly installed with a check valve, and the rear end of the conduit 315 is fixedly connected to the upper rear side opening of the mixing chamber 211.
[0038] Specifically, when pulley 39 drives the stirring rod 32 to rotate, the gear disc 38 and transmission gear 37 work together to drive the dispersing blades 35 on the outer periphery of the rotating seat 34 to rotate. At the same time, the three-way flow control valve 313 sends a large portion of the clean water drawn from the clean water tank 51 into the dilution tank 31 through the conduit 314. This water impacts the pesticide, which has been initially diluted and sent into the dilution tank 31 from the conduit 6, creating a vortex in the lower part of the dilution tank 31. The rotating dispersing blades 35 further disperse the vortex generated by the impact of the conduit 314 on the bottom of the dilution tank 31, thereby further dispersing and mixing the pesticide and clean water. The mixture is conveyed to the upper end of the dilution chamber 31. In winter or spring when the temperature is low, the heater 316 can be activated to heat the mixture of water and pesticide, which facilitates the rapid dissolution of pesticide and the subsequent fusion of the pesticide atomized liquid and water atomized liquid after the temperature is raised. At this time, the stirring blades 33 and the dispersing blades 35 distributed at the upper end of the stirring rod 32 rotate in opposite directions, which can further disperse the vortex formed by the dispersing blades 35, thereby making the secondary dilution of the pesticide mixture more uniform. Through the cooperation of the mixing mechanism 2 and the dilution mechanism 3, the pesticide mixture after the first dilution is diluted a second time in three counter vortex modes, resulting in more uniform dilution.
[0039] In this embodiment, the atomizing mechanism 5 includes a clear water tank 51. A circular seat 52 is fixedly connected to the lower end of the clear water tank 51. A spray chamber 512 is threadedly connected to the lower end of the circular seat 52. A water pump 53 is fixedly connected to the rear side of the inner bottom wall of the clear water tank 51. A conduit 6 54 is fixedly connected to the water outlet end of the water pump 53. A drive chamber 55 is fixedly connected to the lower end of the conduit 6 54. A water wheel 56 is rotatably connected inside the drive chamber 55. A conduit 57 is fixedly connected to the lower end of the drive chamber 55. A quick connector 58 is fixedly connected to the lower end of the conduit 57. A water distribution ring 59 is fixedly connected to the front end of the quick connector 58. Atomizing nozzle 1 510 and atomizing nozzle 2 511 are evenly distributed inside the water distribution ring 59.
[0040] In this embodiment, the lower end of the funnel 318 is connected to the upper end of the conduit 4, the lower end of the conduit 4 is connected to the middle of the upper end of the liquid distribution seat 513, and the outer peripheries of the atomizing nozzle 510 and the atomizing nozzle 511 are fixedly connected to the lower opening of the spray chamber 512.
[0041] In this embodiment, a geared disc 517 is rotatably connected inside the circular seat 52. A drive gear 515 is meshed with the geared disc 517. An electric reducer 516 is fixedly connected to the middle of the drive gear 515. The rear input end of the electric reducer 516 is fixedly connected to the middle of the water wheel 56. A liquid distribution seat 513 is fixedly connected inside the geared disc 517. Atomizing nozzles 514 are evenly distributed at the lower end of the liquid distribution seat 513. A conduit 4 is rotatably connected to the middle of the upper end of the liquid distribution seat 513. The upper end of the conduit 4 is fixedly connected to the lower end of the funnel 318.
[0042] In this embodiment, the front end of the electronically controlled reducer 516 is fixedly connected to the rear end of the clear water tank 51, and the front end of the drive chamber 55 is fixedly connected to the rear end of the electronically controlled reducer 516.
[0043] Specifically, after the diluted pesticide is filtered through filter screen 317, it is pumped into the distributor seat 513 through funnel 318 and conduit 4. It is then atomized and sprayed out through atomizing nozzle 3 514. Simultaneously, water pump 53 is activated, pumping clean water into the drive chamber 55 through conduit 6 54. This, in turn, drives the drive gear 2 515 to rotate via electronically controlled reducer 516, which in turn drives the distributor seat 513 to rotate via gear disc 3 517. This causes the diluted pesticide solution sprayed from atomizing nozzle 3 514 to be sprayed out in a spiral pattern. Meanwhile, the clean water in the drive chamber 55 is pumped into the water distribution ring 59 through conduit 57 and quick connector 58, and then atomized and sprayed out through atomizing nozzles 1 510 and 2 511. The atomized droplets sprayed upwards from atomizing nozzle 1 510 first collide with… The pesticide diluted droplets atomized by the atomizing nozzle 514 undergo a third dilution process. Because the downward-spraying pesticide diluted droplets and water droplets create suction inside the spray chamber 512, the first-diluted droplets accelerate and collide with the droplets sprayed by the atomizing nozzle 511, undergoing a fourth dilution. The pesticide is then sprayed onto the top of the crops in the field, completing the pesticide application. The atomizing mechanism 5 sprays the second-diluted pesticide solution in a spiral shape, merging it with the water droplets. The atomized water droplets are sprayed in both upward and downward directions, resulting in a more uniform and even pesticide application to the crops.
[0044] Working principle: First, all pesticides are mixed with water in a certain proportion to form a paste and stored. The end cap at the top of the pesticide storage tank 28 is opened, and the mixed pesticides are added to the pesticide storage tank 28. Clean water is added to the water tank 51. The main body of the drone 1 is started and flies over the farmland. The servo motor 22 drives the pulley 25 and pulley 39 to rotate through the pulley 23 and the transmission belt 24. The stirring rod 32 drives the impeller 311 to rotate, thereby drawing clean water from the inside of the water tank 51 through the conduit 7 312 and the check valve at the bottom. A small portion of the clean water is sent into the mixing tank 211 through the three-way flow control valve 313 and the conduit 4 315. At the same time, the pulleys 25 on both sides drive the auger 27 to rotate inside the pesticide storage tank 28 through the rotating shaft 26. The pesticide paste is pumped into the mixing chamber 211 through the delivery pipe 214, where it is mixed with water. A servo motor 22 drives bevel gears 29 and 210 to rotate, which in turn drives the two drive gears 213 to transport the mixed pesticide inside the mixing chamber 211 through conduit 26 to the dilution chamber 31. Through the cooperation of the mixing mechanism 2 and the dilution mechanism 3, all pesticides can be mixed into a paste at once according to the actual usage. Compared to the method of preparing the paste after each application of pesticides to the water chamber 51 by the drone body 1, this saves preparation time. Furthermore, compared to the method of pre-mixing pesticide spray solution, the paste-like pesticide is less prone to sedimentation, making it easier to apply to the pesticide using the drone body 1 and the atomizing mechanism 5. The convenience and safety of pesticide spraying in the field are enhanced by the following: When the pulley 39 drives the stirring rod 32 to rotate, the gear disc 38 and the transmission gear 37 work together to drive the dispersing blades 35 on the outer periphery of the rotating seat 34 to rotate. Simultaneously, the three-way flow control valve 313 sends a large portion of the clean water drawn from the clean water tank 51 into the dilution tank 31 through the conduit 314. This impacts the pesticide, which has undergone preliminary dilution and is fed into the dilution tank 31 from the conduit 2 6, creating a vortex in the lower part of the dilution tank 31. The rotating dispersing blades 35 further disperse the vortex generated by the impact of the conduit 314 on the bottom of the dilution tank 31, thus further dispersing and mixing the pesticide and clean water before conveying it to the upper part of the dilution tank 31. In winter or spring when the temperature is low, the heater 316 can be activated to further disperse the pesticide and water. Heating the mixture of water and pesticide facilitates rapid pesticide dissolution and subsequent fusion of the pesticide atomized liquid and water atomized liquid after secondary dilution. At this time, the stirring blades 33 and dispersing blades 35 on the upper end of the stirring rod 32 rotate counter-clockwise, further dispersing the vortex formed by the dispersing blades 35, thus making the secondary dilution of the pesticide mixture more uniform. Through the cooperation of the mixing mechanism 2 and the dilution mechanism 3, the pesticide mixture after primary dilution is diluted a second time using three counter-clockwise vortex methods, resulting in more uniform dilution. After being filtered through the filter screen 317, the diluted pesticide is pumped into the dispensing seat 513 through the funnel 318 and the first conduit 4, and then atomized and sprayed out through the third atomizing nozzle 514. Simultaneously, the water pump 53 is activated, pumping clean water into the drive chamber 55 through the sixth conduit 54.Then, the electronically controlled reducer 516 drives the drive gear 2 515 to rotate, which in turn drives the distributor seat 513 to rotate via the gear disc 3 517, causing the pesticide dilution sprayed from the atomizing nozzle 3 514 to be sprayed out in a spiral shape. At the same time, the clean water in the drive chamber 55 is pumped into the water distribution ring 59 through the conduit 57 and quick connector 58, and then atomized and sprayed out through the atomizing nozzle 1 510 and atomizing nozzle 2 511. The atomized droplets sprayed upward by the atomizing nozzle 1 510 will first collide with the pesticide dilution droplets sprayed by the atomizing nozzle 3 514, performing a third droplet fusion and dilution. Due to the downward spraying of pesticide dilution... The liquid mist and water mist create suction inside the spray chamber 512. The first-diluted mist accelerates and impacts the mist sprayed from the atomizing nozzle 511, undergoing a fourth dilution. This is then sprayed onto the top of the crops in the field, completing the pesticide application. The atomizing mechanism 5 then sprays the second-diluted pesticide solution in a spiral pattern, mixing and diluting it with the water mist. The atomized water mist is sprayed both upwards and downwards, resulting in a more uniform and even distribution of the diluted pesticide mist, thus improving the uniformity of pesticide application to the crops.
