Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1: A pesticide spraying device for agricultural planting, such as... Figures 1-4 As shown, the system includes a flight body 1, support frames 2, rotors 3, protective covers 4, a liquid storage tank 5, a counterweight frame 6, a spraying device, a liquid inlet pipe 13, a first correction frame 16, a second correction frame 17, and a mounting base 18. Four support frames 2 are symmetrically installed on the lower part of the flight body 1. The support frames 2 are arc-shaped supports to enhance structural stability. Rotors 3 are installed at the four corners of the upper part of the flight body 1. Each of the four rotors 3 is covered with a protective cover 4 to isolate and protect the rotors 3, preventing impacts and avoiding damage to crops caused by the high-speed rotation of the rotors 3 hitting the leaves of taller crops during drone flight, thus preventing drone attitude interference and crashes. A mounting base 18 is horizontally installed at the bottom of the flight body 1. The second correction frame 17 is rotatably mounted on the mounting base 18. The second correction frame 17 has a vertically rotating... The aircraft is equipped with a first correction frame 16, which is staggered with a second correction frame 17, allowing for correction in all directions. This ensures that the rotating liquid tank 5 remains vertical, maintaining its vertical position even when the aircraft body 1 is tilted, thus ensuring consistent and accurate spraying and reducing the impact of liquid sloshing on flight stability. A counterweight frame 6 is installed at the bottom of the liquid tank 5 to optimize the overall center of gravity distribution and increase flight stability. Spraying devices are installed on both the liquid tank 5 and the support frame 2 for precise spraying. A liquid inlet pipe 13 is connected to the aircraft body 1, with its upper end connected to the aircraft body 1 and its lower end connected to the liquid tank 5. A threaded cap is installed on the upper end of the liquid inlet pipe 13 to seal it.

[0022] like Figure 2As shown, the spraying device comprises a distribution pipe 7, a first liquid guide pipe 8, a micro water pump 9, a second liquid guide pipe 10 and a spray head 11. The lower part of the liquid storage tank 5 is provided with the distribution pipe 7, which is dispersed into four pipes at four corners. Each pipe is connected with a first liquid guide pipe 8, which can uniformly distribute the liquid in the liquid storage tank 5 to each first liquid guide pipe 8. The upper part of each support frame 2 is provided with a micro water pump 9. One end of the micro water pump 9 is communicated with the top of the adjacent first liquid guide pipe 8, and the other end is connected with the second liquid guide pipe 10. The second liquid guide pipe 10 is arranged on the support frame 2, and the bottom of the second liquid guide pipe 10 is connected with the spray head 11.

[0023] When the unmanned aerial vehicle tilts during flight, the liquid storage tank 5 is suspended between the first and second deviation rectifying frames 16 and 17 under the gravity of the liquid in the liquid storage tank 5 and the counterweight frame 6. When the liquid storage tank 5 is on the freely rotating device, it tends to keep balance along the shortest path (i.e. the vertical line) towards the ground. The first and second deviation rectifying frames 16 and 17 allow the liquid storage tank 5 to keep its vertical posture by rotating in the case of forward and backward tilting and left and right tilting, so as to adapt to the change of the tilt of the unmanned aerial vehicle, thereby ensuring that the surface of the liquid in the liquid storage tank 5 is as horizontal as possible. Then the liquid is transported to the micro water pump 9 through the first liquid guide pipe 8, and is sprayed from the spray head 11 under the control of the micro water pump 9, thereby ensuring uniform spraying of the liquid.

[0024] Example 2: Based on example 1, as shown in Figure 3 The bottom of the flight body 1 is provided with four fixed seats 14, and the outer side of the liquid storage tank 5 is slidingly provided with a positioning frame 12. The top of the positioning frame 12 is provided with four blocks matched with the fixed seats 14, so as to facilitate the fixed clamping of the positioning frame 12 after moving upward, thereby ensuring that the liquid storage tank 5 is stably fixed on the flight body 1, improving the stability of the liquid storage tank 5 during flight, and reducing the problems of liquid waste and uneven spraying caused by shaking. The matched parts of the positioning frame 12 and the fixed seat 14 are both provided with a positioning spring 15. The positioning spring 15 can play a buffering and stabilizing role when the positioning frame 12 moves upward. When the flight body accelerates, decelerates or adjusts the flight posture, the positioning spring 15 can absorb part of the vibration, thereby reducing the shaking of the liquid storage tank 5 and maintaining the stability of the liquid spraying.

[0025] As shown in Figure 5The stirring screw plate 19, the motor 20, the steel framework 21 and the sponge sleeve 22 are further shown, the motor 20 is arranged on the liquid storage tank 5, the shaft coupling of the motor 20 is connected with the stirring screw plate 19 penetrating through the top of the liquid storage tank 5, for rapidly stirring the liquid medicine, preventing the liquid medicine from depositing or stratifying, the steel framework 21 is connected on the stirring screw plate 19, the sponge sleeve 22 is sleeved on the steel framework 21, the sponge sleeve 22 is close to the inner side of the liquid storage tank 5, facilitating wall scraping operation at the inner wall, synchronously scraping the residual liquid medicine on the wall surface, avoiding the problem of waste caused by the residual liquid medicine.

[0026] When the liquid in the liquid storage tank 5 needs to be stirred or cleaned, the unmanned aerial vehicle is landed on the ground, the positioning frame 12 of the liquid storage tank 5 is extruded and moves up to be clamped in the fixed seat 14, so that the liquid storage tank 5 is fixed, the posture of the liquid storage tank 5 is stable, liquid medicine is added or cleaned and maintained, the motor 20 is started, so that the stirring screw plate 19 is driven to rotate to stir the liquid in the liquid storage tank 5, so that the liquid medicine is uniformly mixed, at the same time, the steel framework 21 and the sponge sleeve 22 thereon are scraped along the inner wall of the liquid storage tank 5, the residual liquid medicine on the wall surface is scraped, and the problem of waste caused by the residual liquid medicine can be avoided.

It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications, improvements and substitutions can be made, which all belong to the protection scope of the present application.
