[0023] 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.

[0024] In the prior art, Chinese Patent Publication No. CN218303055U discloses an agricultural spraying drone.

[0025] The inventor found that although this patent can drive away birds and prevent the drone from colliding with birds, if the drone collides with a utility pole due to improper operation during flight, it will be damaged, causing property losses to the farmer.

[0026] like Figure 1-3 As shown, a UAV with a shock absorption function includes a UAV body 1, a pneumatic shock absorption mechanism 2, and a protective plate 3;

[0027] The protective plate 3 is arranged on the front of the drone body 1 through the gas pressure shock absorbing mechanism 2;

[0028] The pneumatic shock absorbing mechanism 2 includes a base 21, a movable rod 22, an air bag 23, and a limit block 24;

[0029] There are two bases 21, the front base 21 is fixedly connected to the protective plate 3, the back base 21 is fixedly connected to the drone body 1, there are two movable rods 22, one end of the two movable rods 22 penetrates into the interior of the airbag 23 and is fixedly connected to the limiting block 24, and the other ends of the two movable rods 22 away from the airbag 23 are fixedly connected to the two bases 21 respectively.

[0030] Specifically, the airbag 23 is filled with high-pressure gas.

[0031] like Figure 3 As shown, the left and right sides of the airbag 23 are fixedly connected with a slide groove 25 , and the interior of the slide groove 25 is slidably connected with a slider 26 , and the slider 26 is hinged to the two bases 21 through a connecting rod 27 .

[0032] like Figure 4 As shown, a pesticide storage bin is provided inside the drone body 1, and liquid pesticide is provided inside the pesticide storage bin. A buoyancy mechanism 4 is provided inside the pesticide storage bin, and the buoyancy mechanism 4 includes a rotating rod 41, and the rotating rod 41 is rotatably connected to the inner wall of the pesticide storage bin through a bearing.

[0033] like Figure 4 As shown, one end of the rotating rod 41 is fixedly connected to an inclined rod 42, and the bottom end of the inclined rod 42 is fixedly connected to a floating ball 43, and the floating ball 43 floats on the liquid pesticide.

[0034] Specifically, the floating ball 43 is provided to drive the inclined rod 42 to rotate.

[0035] like Figure 4 As shown, a movable block 44 is fixedly connected to the top of the inclined rod 42, a switch 45 is fixedly connected to the top inner wall of the pesticide storage bin, and a pesticide nozzle 46 is fixedly connected to the bottom of the drone body 1.

[0036] Specifically, the switch 45 is connected to the user's mobile phone signal.

[0037] like Figure 1 As shown, the left and right sides of the drone body 1 are fixedly connected with horizontal support rods 5, the top of the horizontal support rods 5 is fixedly connected with vertical support rods 6, the top of the vertical support rods 6 is fixedly connected with horizontal rods 7, and the top of the horizontal rods 7 is connected with propellers 8.

[0038] It is worth noting that, for the convenience of control, in this embodiment, when the switch 45 is pressed, a signal is sent to the user's mobile phone to remind the user that the liquid pesticide in the pesticide storage tank is exhausted. The above are all existing technologies and are not the main innovations, so they will not be described in detail here.

[0039] The working principle of the utility model is as follows:

[0040] When the drone body 1 hits a telephone pole during flight, the protective plate 3 will first withstand the impact and move toward the drone body 1. As a result, the protective plate 3 drives the base 21 to move toward the airbag 23. The base 21 moves toward the airbag 23 and drives the movable rod 22 to press into the airbag 23. When the high-pressure gas inside the airbag 23 is squeezed, the impact force generated by the impact is buffered. During the flight of the drone body 1, the liquid pesticide in the pesticide storage bin is sprayed out through the pesticide nozzle 46. When the liquid pesticide in the pesticide storage bin is about to run out, the float 43 will drop as the remaining amount of the liquid pesticide decreases. The float 43 drops and drives the movable block 44 to rise through the inclined rod 42, and presses the switch 45. When the switch 45 is pressed, a signal is sent to the user's mobile phone to remind the user that the liquid pesticide in the pesticide storage bin is exhausted.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
