DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figure 1-4The utility model provides a technical solution: a plant protection drone for spraying pesticides on fruit trees, comprising:

[0026] A housing 10, to which a GPS is connected. The GPS is used for positioning the drone. A propeller 11 is connected to the housing 10;

[0027] A landing gear 14, wherein the landing gear 14 is fixedly connected to the housing 10, and the landing gear 14 is used for landing or taking off the UAV;

[0028] A medicine box 12, the medicine box 12 is arranged at the bottom of the housing 10, the medicine box 12 is fixedly connected to the housing 10, and a liquid inlet 13 is opened on one side of the medicine box 12. By arranging the medicine box 12 at the bottom of the housing 10, the center of gravity of the drone can be lowered, so that the drone can fly more smoothly in the air and during the process of spraying pesticides. After the drone lands, the liquid medicine can be replenished through the liquid inlet 13 at the top of the medicine box 12;

[0029] The spraying assembly 20 is arranged at the bottom of the medicine box 12. The spraying assembly 20 is used to spray the liquid medicine in the medicine box 12 outward. The drone is launched into the air. During the flight, the spraying assembly 20 at the bottom of the medicine box 12 is aimed at the side and bottom of the fruit tree to spray the liquid medicine.

[0030] The spray assembly 20 also includes a spray rod pump 21, which is arranged at the bottom of the medicine box 12. The spray rod pump 21 is connected to the bottom of the medicine box 12. A spray rod 22 is arranged at the bottom of the spray rod pump 21, and the spray rod 22 is vertically arranged at the bottom of the spray rod pump 21. At least two nozzles 23 are arranged on the outer wall of the spray rod 22, and a protection component 24 for protecting the nozzle 23 is arranged on the outer side of the nozzle 23. During use, the spray rod pump 21 sprays the liquid medicine in the medicine box 12 outward through the spray rod 22 and the nozzle 23. Since the nozzle 23 is arranged on the side wall of the spray rod 22, it is convenient for the nozzle 23 to spray the liquid medicine to the side wall of the fruit tree. During the flight of the drone, it is only necessary to place the spray rod 22 on the side wall of the fruit tree, and the drone can complete the spraying operation when it is suspended in the air.

[0031] The spray rod 22 is connected to the spray rod pump 21, and the spray rod 22 is threadedly connected to the spray rod pump 21. By threading the spray rod 22 and the spray rod pump 21, when the spray rod 22 needs to be stored or replaced, the spray rod 22 can be separated from the spray rod pump 21 by rotating the spray rod 22, thereby completing the storage or replacement purpose, the operation is simple, and space is saved.

[0032] The protection component 24 also includes a protection shell 241, and the protection shell 241 wraps the nozzle 23. By wrapping the protection shell 241 on the outside of the nozzle 23, the nozzle 23 can be prevented from being bumped. The protection shell 241 is located at one end of the nozzle 23 where the liquid is sprayed and is fixedly connected to a protection net 242. A liquid outlet 243 is opened in the middle of the protection net 242. The protection net 242 is fixedly connected to the front end of the protection shell 241, and the protection net 242 is connected to the outside world, which can prevent the accumulation of liquid medicine in the protection shell 241 while protecting the nozzle 23 from being bumped. The liquid outlet 243 in the middle of the protection net 242 is convenient for the nozzle 23 to spray liquid medicine. The outer wall of the protection shell 241 is polished, and the polished protection shell 241 is not easily entangled by leaves and branches.

[0033] The protective shell 241 is cylindrical in shape. The cylindrical protective shell 241 is used to wrap the nozzle 23 while its smooth shell can avoid being entangled with leaves and branches as much as possible.

[0034] The spray rod 22 is provided with a base 31 at the spray head 23, and the protective shell 241 is rotatably connected to the base 31. By rotatably connecting the protective shell 241 to the base 31, when branches and leaves contact and rub against the surface of the protective shell 241, the protective shell 241 can rotate accordingly to avoid entanglement.

[0035] According to the above embodiment, this solution also has embodiment 2:

[0036] The cross-sectional shape of the protective shell 241 is an isosceles trapezoid. By designing the cross-sectional shape of the protective shell 241 to be an isosceles trapezoid, its inclined surface is not easily hooked by leaves and branches when the drone moves up and down, thereby minimizing entanglement, making the spraying assembly 20 smoother in the process of spraying the sides and bottom of the fruit trees.

[0037] The utility model also provides a parking platform for spraying pesticides on fruit trees, comprising:

[0038] The parking platform 41 has round rods 42 fixedly connected to the four corners. The parking platform 41 is elevated by the round rods 42 around it, so that the spray rod 22 can contact the ground when the drone is parked.
