Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles, and in particular relates to a pesticide spraying mechanism for an unmanned aerial vehicle. Background Art

[0002] With the advancement of science and technology, agricultural production is becoming more and more automated. Pesticide spraying drones are suitable for spraying pesticides on farmland. They use the flight of drones and load barrels of liquid medicine to spray the medicine on farmland, thereby eliminating manual spraying of pesticides. The step of pesticide spraying is gradually replaced by machines instead of manpower, greatly improving the efficiency of pesticide spraying; standardized and mechanized use of pesticides can also reduce the pollution of pesticides to the field environment.

[0003] The existing drone pesticide spraying mechanism mostly uses atomizing nozzles. Although it can increase the spraying area, because the nozzles are mounted on both sides of the drone, when encountering wind during flight, the liquid medicine is easily splashed on the drone body and landing gear surface, which will cause corrosion to the drone in the long run. In addition, the liquid medicine contains pesticide particles, which can easily clog the nozzles when mixed unevenly, affecting the spraying efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a drone pesticide spraying mechanism, which drives the stirring blades through the rotor to perform secondary stirring of the medicine liquid inside the nozzle, thereby preventing the filter plate and the nozzle from being blocked due to uneven mixing of the medicine liquid, thereby improving the spraying efficiency, and also preventing the medicine liquid sprayed from the nozzle from splashing on the surface of the drone or the landing gear, thereby avoiding the stability of the drone or the landing gear surface being affected by the corrosion of the medicine liquid.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A drone pesticide spraying mechanism comprises a nozzle and a rotor, wherein one side of the nozzle is slidably assembled with a splash guard, one side of the splash guard is fixedly connected with a splash guard, an eddy current plate is fixedly connected inside the rotor, a rotating column second is rotatably connected to the center of the eddy current plate, an inner wall of the rotating column second is fixedly connected with a reduction gear set two, a rotating shaft is fixedly connected to the bottom of the rotor, a reduction gear set one is transmission-assembled on the outer wall of the rotating shaft, a rotating column first is fixedly connected to the outer wall of the reduction gear set one, the rotating shaft is transmission-assembled with the reduction gear set two, a filter plate is fixedly connected to the inner wall of the nozzle and located above the eddy current plate, a filter hole is array-through-opened at the bottom of the filter plate, a stirring blade is fixedly connected to the outer wall of the rotating column first and located inside the filter plate, a roller is fixedly connected to the outer wall of the rotating column second and located inside the filter plate, and an engaging nail for rolling engagement with the filter hole is fixedly connected to the outer wall of the roller in an array.

[0007] The splash-proof frame is slidably connected to the spray head via a sliding rod.

[0008] The outer wall of the nozzle is fixedly connected with a spiral tube, and the splash-proof frame is threadedly connected with the spiral tube through a screw rod.

[0009] A water pipe is fixedly connected to one side of the top of the nozzle, and the rotor is rotatably assembled on the top of the nozzle.

[0010] The first rotating column is rotationally connected to the second reduction gear set.

[0011] The technical effect achieved by the utility model is as follows: the rotor drives the stirring blades to perform secondary stirring of the medicine liquid inside the nozzle, which can prevent the filter plate and the nozzle from being blocked due to uneven mixing of the medicine liquid, thereby improving the spraying efficiency, and can also prevent the medicine liquid sprayed from the nozzle from splashing on the surface of the UAV or the landing gear, thereby avoiding the corrosion of the surface of the UAV or the landing gear due to the medicine liquid and affecting the stability.

DETAILED DESCRIPTION

[0017] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0018] like Figure 1-3As shown, a drone pesticide spraying mechanism includes a nozzle 1 and a rotor 2, a splash guard 101 is slidably assembled on one side of the nozzle 1, a splash guard 102 is fixedly connected to one side of the splash guard 101, the splash guard 101 is slidably connected to the nozzle 1 through a sliding rod 103, a spiral tube 105 is fixedly connected to the outer wall of the nozzle 1, the splash guard 101 is threadedly connected to the spiral tube 105 through a screw 104, a water pipe 106 is fixedly connected to one side of the top of the nozzle 1, the rotor 2 is rotatably assembled on the top of the nozzle 1, a vortex plate 211 is fixedly connected to the inside of the rotor 2, a rotating column 206 is rotatably connected to the center of the vortex plate 211, a reduction gear set 205 is fixedly connected to the inner wall of the rotating column 206, and a rotating shaft 203 is fixedly connected to the bottom of the rotor 2.
