[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0032] like Figures 1-7 As shown, the present invention provides a pesticide sprayer for drones, including a drone body 10, and a spraying mechanism 20 that can spray pesticides on crops on the drone body 10.
[0033] The spraying mechanism 20 includes a water tank 21 and a mounting base 22 that are screwed to the bottom of the drone body 10. The water tank 21 stores pesticides inside. The mounting base 22 is equipped with a spraying component 23 that can spray pesticides. The mounting base 22 is also equipped with a rotating component 24 that can change the spraying angle.
[0034] In more detail, the spray assembly 23 includes a rotating seat 231 fixedly mounted on the mounting base 22. A rotating rod 232 is rotatably connected to the rotating seat 231. The rotating assembly 24 can drive the rotating rod 232 to swing back and forth on the rotating seat 231, thereby increasing the spraying area. One end of the rotating rod 232 is fixedly connected to a water inlet pipe 233. A connecting pipe 234 is installed on one side of the water inlet pipe 233. Several nozzles 235 are installed at the bottom end of the connecting pipe 234. A water supply pipe 236 is installed between the water inlet pipe 233 and the water tank 21. In use, a micro water pump enables the water supply pipe 236 to... The pesticide in the water tank 21 is transported to the inlet pipe 233, and then enters the connecting pipe 234 through the inlet pipe 233. The pesticide is then atomized and sprayed out through several nozzles 235 at the bottom of the connecting pipe 234. The inlet pipe 233 is internally connected to a stirring blade 237. When the pesticide enters the inlet pipe 233, the impact force of the pesticide acts on one of the blades of the stirring blade 237. As the pesticide is continuously transported, the stirring blade 237 also begins to rotate. The rotating stirring blade 237 stirs the pesticide inside the inlet pipe 233, making the pesticide more evenly mixed.
[0035] In more detail, the water supply pipe 236 is a flexible hose with a slack. One end of the water supply pipe 236 is located at the bottom of one of the blades of the stirring blade 237, so that the stirring blade 237 can rotate due to the impact of the pesticide.
[0036] In more detail, the nozzles 235 are equidistantly spaced, and the stirring blades 237 are made of rubber. Pesticides usually have a certain degree of chemical corrosiveness, and the rubber stirring blades 237 have good corrosion resistance, are not easily corroded by pesticides, and can extend their service life.
[0037] In more detail, the rotating assembly 24 includes a vertical plate 241 fixedly mounted on the mounting base 22. A motor 242 is fixedly mounted on one side of the vertical plate 241, and a rotating frame 243 is rotatably connected to the other side of the vertical plate 241. The rotating frame 243 can rotate by being driven by the motor 242. A sliding groove is provided on the rotating frame 243, and several through holes 244 are symmetrically provided on both sides of the sliding groove. A sliding frame 245 is slidably connected in the sliding groove. The sliding frame 245 can move through the sliding groove and can be installed in different positions in conjunction with the corresponding through holes 244, so that the rotation range will change. A ball 246 is movably connected inside the sliding frame 245. The ball 246 can rotate in the sliding frame 245. A connecting rod 247 is fixedly mounted on one side of the ball 246, and a concave frame 248 is rotatably connected to the surface of the rotating rod 232.
[0038] When the spray angle needs to be adjusted, the motor 242 is started to drive the rotating frame 243 to start rotating. The rotating frame 243 then drives the sliding frame 245 to start rotating. As the sliding frame 245 rotates, the ball 246 moves within the sliding frame 245, causing the connecting rod 247 to move the concave frame 248 up and down. At the same time, the concave frame 248 also drives the rotating rod 232 to swing left and right, which in turn causes the connecting pipe 234 to swing left and right, thereby increasing the spray range.
[0039] The sliding bracket 245 can move through the slide groove, and can be installed in different positions in conjunction with the corresponding through hole 244, so that the range of rotation will change.
[0040] In more detail, the rotating frame 243 is fixedly connected to the output end of the motor 242, and the rotating frame 243 can be driven to rotate by the motor 242. The sliding frame 245 is fixed to one of the through holes 244 by screws, and one end of the concave frame 248 is fixedly installed on the connecting rod 247.
[0041] Working principle: After the drone body 10 takes off, the micro water pump enables the water delivery pipe 236 to transport the pesticide in the water tank 21 to the water inlet pipe 233. The pesticide enters the connecting pipe 234 through the water inlet pipe 233, and is sprayed out in atomized form through several nozzles 235 at the bottom of the connecting pipe 234. When the pesticide enters the water inlet pipe 233, the impact force of the pesticide acts on one of the blades of the stirring blade 237. As the pesticide is continuously transported, the stirring blade 237 will also start to rotate. The rotating stirring blade 237 stirs the pesticide inside the water inlet pipe 233, making the pesticide more evenly mixed.
[0042] When the spray angle needs to be adjusted, the start motor 242 drives the rotating frame 243 to start rotating. The rotating frame 243 then drives the sliding frame 245 to start rotating. As the sliding frame 245 rotates, the ball 246 moves within the sliding frame 245, causing the connecting rod 247 to move the concave frame 248 up and down. At the same time, the concave frame 248 also drives the rotating rod 232 to swing left and right, which in turn causes the connecting pipe 234 to swing left and right, thereby increasing the spray range.
[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
