[0022] 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.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-4This utility model provides a drone-based precision pesticide atomization spraying device, comprising a drone body 1; a liquid storage tank 11 is fixedly connected to the side wall of the drone body 1; a dual-axis motor 12 is fixedly connected to the side wall of the liquid storage tank 11; a pair of screws 13 are fixedly connected to the output end of the dual-axis motor 12; the screws 13 are symmetrically arranged on both sides of the dual-axis motor 12 and have the same structure; a connecting block 14 is threadedly connected to the side wall of the screw 13; the screws 13 penetrate the wall of the connecting block 14 and are threadedly connected to it; a spray pipe 15 is fixedly connected to the side wall of the dual-axis motor 12; a plurality of first spray holes 16 are evenly opened on the side wall of the spray pipe 15; a pair of connecting pipes 17 are symmetrically fixed between the liquid storage tank 11 and the spray pipe 15; a pair of extension pipes 18 are symmetrically slidably connected to the inner side wall of the spray pipe 15; a plurality of second spray holes are evenly opened on the side wall of the extension pipes 18. 19; The extension tube 18 and the connecting block 14 are fixedly connected; In use, by starting the dual-axis motor 12, the screw 13 is rotated by the dual-axis motor 12. As the screw 13 rotates, the connecting block 14 can move. At this time, the connecting block 14 can drive the extension tube 18 to move, so that it slides in the spraying pipe 15, and the length of the extension tube 18 can be adjusted to complete the adjustment of the spraying range. Then, the pesticide in the storage tank 11 is transported into the spraying pipe 15 through the connecting tube 17. Then, it is sprayed to the outside through the first spraying hole 16 and the second spraying hole 19. In this process, the extension tube 18 slides in the spraying pipe 15, which can play the role of adjusting the spraying range when the UAV body 1 is used, improving the practicality of the UAV body 1, increasing the adaptability to spraying different areas, and thus reducing the impact of inconvenient adjustment on practicality.

[0025] Furthermore, such as Figures 1-4 As shown, multiple telescopic rods 2 are fixedly connected to the side wall of the spray pipe 15; the telescopic rods 2 are evenly distributed on the side wall of the spray pipe 15 and have the same structure; a first spring 21 is sleeved on the outside of each telescopic rod 2; the ends of the telescopic rods 2 and the first spring 21 are fixedly connected to the same sponge block 22; a pair of iron wires 23 are symmetrically fixed to the side wall of the sponge block 22; during use, as the extension pipe 18 slides, the elasticity of the first spring 21 pushes the sponge block 22, making full contact between the sponge block 22 and the side wall of the extension pipe 18, while the telescopic rods 2 extend and retract to maintain the smooth movement of the sponge block 22. When the extension tube 18 moves, the sponge block 22 can wipe the side wall of the extension tube 18 to remove the attached dust and impurities. At the same time, the iron wire 23 can be used to fix the wall of the sponge block 22. During this process, wiping the side wall of the extension tube 18 by the sponge block 22 can clean the dust and impurities attached to the surface of the extension tube 18, improve the smoothness of the extension tube 18 when sliding in the spray tube 15, and reduce the occurrence of dust and impurities entering the spray tube 15. At the same time, the iron wire 23 can increase the tear resistance of the sponge block 22 during use, thereby increasing the service life of the sponge block 22.

[0026] Furthermore, such as Figures 1-4 As shown, a slide rail 3 is fixedly connected to the side wall of the connecting block 14; an insert block 31 is slidably connected to the inner side wall of the slide rail 3; a spring rod 32 is fixedly connected to the side wall of the insert block 31; and a wax block 33 is fixedly connected to the end of the spring rod 32. In use, by inserting the insert block 31 into the slide rail 3, a certain frictional force is generated under full contact between the two to fix the wax block 33. Then, the spring rod 32 pushes the wax block 33 so that the wax block 33 can fully contact the side wall of the screw 13. At this time, the wax block 33 can be used to wipe the surface of the screw 13 to increase the lubrication between the screw 13 and the connecting block 14. During this process, the wax block 33 can lubricate the rotation between the screw 13 and the connecting block 14, improving the smoothness of the connecting block 14 during movement. At the same time, the insert block 31 can facilitate the disassembly and replacement of the wax block 33, and the spring rod 32 can increase the constant contact between the wax block 33 and the side wall of the screw 13, thereby improving the wiping effect.

[0027] Furthermore, such as Figures 1-4 As shown, a pair of second springs 4 are fixedly connected to the side wall of the drone body 1; the second springs 4 are symmetrically arranged on both sides of the drone body 1 and have the same structure; a protective plate 41 is fixedly connected to the end of the second spring 4; in use, when the drone body 1 is landing, the protective plate 41 can first contact the ground, and at the same time squeeze the second spring 4 to perform extension and contraction movement and apply a certain reaction force to buffer the impact force when the drone body 1 is descending. In this process, the elasticity of the second spring 4 can play a buffering role when the drone body 1 is landing, reducing the impact force from being too large and easily causing damage to the drone body 1, thereby increasing the protection of the drone body 1 and improving its service life.

[0028] Furthermore, such as Figures 1-4 As shown, a pair of elastic plates 5 are fixedly connected to the side wall of the slide rail 3; the elastic plates 5 are symmetrically arranged on both sides of the slide rail 3 and have the same structure; a sponge strip 51 is fixedly connected to the side wall of the elastic plate 5; in use, when the insert 31 is inserted into the slide rail 3, the insert 31 will squeeze the elastic plates 5 on both sides, and the elasticity of the elastic plates 5 will also apply a certain reaction force to the insert 31. Then the insert 31 will slide towards the middle of the elastic plates 5 on both sides, and the elastic plates 5 can make the sponge strip 51 fully fit with the side wall of the insert 31. The sponge strip 51 can be used to wipe the side wall of the insert 31. In this process, the elastic plates 5 can play a limiting role when inserting the insert 31 into the slide rail 3, improving the convenience of installing the wax block 33. At the same time, the sponge strip 51 can clean the dust and impurities attached to the side wall of the insert 31, so as to increase the smoothness of the insert 31 sliding in the slide rail 3.

[0029] Furthermore, such as Figures 1-4 As shown, a pair of protrusions 6 are symmetrically fixed to the inner sidewall of the slide rail 3; a pair of elastic blocks 61 are symmetrically fixed to the sidewall of the insert block 31. In use, when the insert block 31 is inserted into the slide rail 3, the elastic blocks 61 will contract under the pressure of the protrusions 6. When the insert block 31 is fully inserted into the slide rail 3, it will quickly reset and lock in place by utilizing the elasticity of the elastic blocks 61. During this process, the protrusions 6 and the elastic blocks 61 are staggered and locked together, which can increase the fixing effect of the insert block 31 in the slide rail 3 and improve the firmness of the wax block 33 during use.

[0030] Working principle: In use, the dual-axis motor 12 is started, which drives the screw 13 to rotate. As the screw 13 rotates, the connecting block 14 moves, which in turn moves the extension tube 18, allowing it to slide within the spray pipe 15. This adjusts the length of the extension tube 18 to regulate the spraying range. Then, the pesticide from the storage tank 11 is transported into the spray pipe 15 through the connecting tube 17, and finally sprayed outwards through the first spray hole 16 and the second spray hole 19. During use, the extension tube 18 slides... During the process, the elasticity of the first spring 21 pushes the sponge block 22, making it fully contact the side wall of the extension tube 18. Meanwhile, the telescopic rod 2 extends and retracts to maintain the smooth movement of the sponge block 22. As the extension tube 18 moves, the sponge block 22 wipes the side wall of the extension tube 18, removing dust and impurities. Simultaneously, the wire 23 secures the sponge block 22. In use, the insert block 31 is inserted into the slide rail 3, and the full contact between the two generates friction, which cleans the wax block 33. After fixing, the spring rod 32 pushes the wax block 33, allowing it to fully contact the side wall of the screw 13. The wax block 33 then wipes the surface of the screw 13 to increase lubrication between the screw 13 and the connecting block 14. During use, when the drone body 1 lands, the protective plate 41 contacts the ground first, simultaneously compressing the second spring 4 to extend and retract, applying a certain reaction force to buffer the impact of the drone body 1's descent. During use, when the insert block 31 is inserted into the slide rail 3, the insert block 3... The elastic plate 5 on both sides will be squeezed, and the elasticity of the elastic plate 5 will also apply a certain reaction force to the insert 31. Then the insert 31 will slide towards the middle of the elastic plate 5 on both sides, and the elastic plate 5 can make the sponge strip 51 fully fit with the side wall of the insert 31. The sponge strip 51 can be used to wipe the side wall of the insert 31. When in use, when the insert 31 is inserted into the slide rail 3, the elastic block 61 will be squeezed by the protrusion 6 and will contract. When the insert 31 is fully inserted into the slide rail 3, the elasticity of the elastic block 61 will quickly reset and lock it.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
