Description

Technical Field

[0001] The invention relates to the technical field of fertilizing unmanned aerial vehicles, in particular to a unmanned aerial vehicle capable of evenly fertilizing. Background Art

[0002] Fertilizer UAV is a kind of intelligent equipment used in the agricultural field, usually composed of a flight platform (mainly multi-rotor UAV), a navigation flight control system, a fertilization system and other parts. With the help of advanced navigation technology, it can fly accurately according to the pre-set route and realize automated and intelligent fertilization operations. Its fertilization system can spread fertilizer evenly on the farmland. By adjusting parameters such as flight speed, altitude and flow rate of the fertilization device, it can accurately control the amount and range of fertilizer according to the needs of different farmlands and crops. Compared with traditional manual fertilization, fertilizer UAV has the significant advantage of high efficiency. It can complete the fertilization of large areas of farmland in a short time, greatly saving manpower and time costs; at the same time, it can also ensure the uniformity of fertilization, improve the quality of fertilization, reduce fertilizer waste and environmental impact, especially suitable for farmland with complex terrain or large area, providing strong support for the efficient and precise production of modern agriculture.

[0003] In today's agricultural production, although fertilization drones have been used to a certain extent, the existing fertilization drones have exposed many problems that need to be solved in the actual operation process. At present, the vast majority of fertilization drones on the market have great limitations in their fertilization processing methods, and can often only carry out fertilization operations in a single direction. This one-way fertilization mode makes the distribution of fertilizers in farmland extremely uneven. From the perspective of crop planting layout, the growth of crops in farmland is not completely regular and uniform, and the fertilizer requirements of crops in different regions are also different. One-way fertilization is difficult to meet the diverse fertilization needs, resulting in excessive fertilizers in some areas, causing waste, and insufficient fertilizers in some areas, affecting crop growth. In addition, when it comes to fertilization by spraying fertilizer water, the existing fertilization drone design has obvious defects. In order to achieve the spraying of fertilizer water, special electrical equipment has to be additionally equipped, the most typical of which is the water pump and other structures. Although these auxiliary equipment can help complete the fertilization operation to a certain extent, they bring a series of negative effects. From a physical perspective, the additional auxiliary equipment undoubtedly adds significant additional weight to the drone. The flight flexibility and maneuverability of the drone are therefore greatly reduced. In terms of energy consumption, the operation of these auxiliary equipment consumes a lot of electricity, which greatly reduces the flight time and operating range of the drone under the limited battery capacity. Originally, a single charge could complete a large area of ​​fertilization tasks, but due to the energy consumption of the auxiliary equipment, the drone needs to return to charge frequently, which greatly reduces the efficiency of the fertilization operation.

[0018] An injection hole is provided at the upper end of the fertilizer storage box 2, and a sealing plug 3 is provided in a threaded sleeve inside the injection hole.

A control valve 1018 is fixedly arranged near the fertilizer storage box 2 on the body of the fertilizer pipe 1017, and the lower end of the fixed block 1025 is fixedly arranged on the upper end of the pressure plate 1020. A second connecting rod 1021 is fixedly arranged on both sides of the upper end surface of the pressure plate 1020, and the upper end of the second connecting rod 1021 is fixedly arranged on the lower end of the upper support plate 9. The pressure plate 1020 is rotatably sleeved on the shaft body of the rotating shaft 1012 at the lower end of the triangular push plate 1011. An air pump piston is fixedly arranged at one end of the piston rod 1024, and is located inside the pressure cylinder 1026. A pressurized pipe 1016 is provided between the fertilizer storage box 2 and the pressurized gas cylinder 1026. A one-way valve 1019 is fixedly provided on the body of the pressurized pipe 1016 near the fertilizer storage box 2. The triangular push plate 1011 and the movable plate 1023 are located in the same plane.

[0019] The core power source of this UAV is a dual-axis motor 4, whose output end not only drives the rotor blades 5 to achieve flight, but also drives the triangular push plate 1011 to rotate through the rotating shaft 1012. The three prongs of the triangular push plate 1011 push the movable plate 1023 to one side during the rotation process, and at the same time squeeze the thrust spring 1028. When the prongs are separated from the movable plate 1023, the thrust spring 1028 pushes the movable plate 1023 back to its original position, thereby realizing the reciprocating motion of the piston rod 1024. The piston motion of the piston rod 1024 provides continuous air pressure for the pressurized gas cylinder 1026, and injects the gas into the fertilizer storage box 2 through the pressurized pipe 1016 to achieve efficient pressurization. This design significantly improves the spraying efficiency of the fertilizer, and at the same time uses the one-way valve 1019 to prevent backflow and ensure the stability of the spraying process.

[0020] In addition, when the small rod 1010 rotates around the rotating shaft 1012, it drives the inclined rod 1013 to move up and down, thereby driving the swing rod 1015 to swing. The swing rod 1015 drives the second and second gears 105 and the pipe installation rod 107 to swing left and right through the meshing action of the first and second gears 102 and the third gear 1014, so that the fertilizer pipe 1017 can achieve swing-type spraying. This swing spraying method ensures that the fertilizer is distributed more evenly and comprehensively in the farmland, avoiding the problem of uneven fertilizer distribution caused by the traditional unidirectional fertilization mode.

[0021] Traditional fertilization drones usually need to be equipped with additional electrical equipment such as water pumps to achieve fertilizer water spraying, which not only increases the weight of the drone, but also greatly increases energy consumption. However, this technology cleverly uses the extra power of the dual-axis motor 4 to achieve pressurization and swing spraying functions through a mechanical linkage structure without the need for additional electrical equipment. This design significantly reduces the weight of the drone, improves its flight flexibility and maneuverability, while reducing energy consumption and extending the drone's operating time and range.

[0022] The drone achieves precise control of the fertilization process through the control valve 1018 and the one-way valve 1019. The control valve 1018 is used to control the opening and closing of the fertilizer pipe 1017 to ensure the accuracy and controllability of fertilizer spraying; the one-way valve 1019 prevents the backflow of pressurized gas and fertilizer, ensuring the stability and reliability of the spraying process. This precise control mechanism not only improves the quality of fertilization, but also reduces fertilizer waste and environmental impact.

[0023] The design of this technology enables it to adapt to the operation requirements of complex terrain and large areas of farmland. Through swing spraying and efficient pressurization, the drone can achieve precise fertilization under different terrains and crop requirements to meet diverse fertilization needs. In addition, the shock-absorbing support legs 7 and side panel group 8 structures equipped with the drone enhance its stability and adaptability, enabling it to complete fertilization operations safely and efficiently in complex terrain.

[0024] Since this drone adopts swing-type spraying and precise control mechanism, fertilizer can be evenly distributed in the farmland, avoiding the problem of too much or insufficient fertilizer in some areas. This uniform fertilization method significantly reduces fertilizer waste, while reducing the negative impact of excessive fertilization on the farmland ecological environment, which meets the requirements of sustainable development of modern agriculture. Through innovative mechanical structure and power transmission system, the present invention achieves multiple advantages such as efficient pressurization, uniform spraying, precise control, adaptability to complex terrain and large-scale farmland operations, while reducing fertilizer waste and environmental impact, providing strong support for the precision and intelligence of modern agriculture.

[0025] Working principle: When in use, the drone body 6 is used to install batteries, controllers and other related drone key structures, and the device is equipped with a remote control to control the drone. Before fertilizing, open the sealing plug 3 to inject a certain amount of fertilizer water, and then operate the drone to start the dual-axis motor 4. The output end of the dual-axis motor 4 rotates to drive the rotor blades 5 to rotate, and the drone can take off, while driving the rotating shaft 1012 to rotate. The rotation of the rotating shaft 1012 drives the triangular push plate 1011 to rotate, and at the same time drives the small rod 1010 to rotate around the rotating shaft 1012. When the triangular push plate 1011 rotates, the triangular push plate 1011 rotates, and the small rod 1010 rotates around the rotating shaft 1012. The three prongs of the triangular push plate 1011 will push the movable plate 1023, so that the movable plate 1023 moves to one side, and the thrust spring 1028 is squeezed at the same time. Since the triangular push plate 1011 is a special triangular structure, the three prongs do not push during the rotation process. Under the action of the thrust spring 1028, the movable plate 1023 returns to its original position, so that the piston rod 1024 can continuously make a piston movement, and the gas added by the pressurized gas cylinder 1026 can be injected into the fertilizer storage box 2 through the pressurized pipe 1016, so as to achieve the effect of pressurization, increase the efficiency of water spraying, and use the one-way valve 1019 to prevent backflow; During the rotation of the small rod 1010 around the rotating shaft 1012, the pulling inclined rod 1013 will continue to move up and down, and at the same time drive the swing rod 1015 to swing up and down. During the swinging of the swing rod 1015, the No. 3 gear 1014 can be driven to rotate left and right through the No. 1 and a half gears 102. The No. 3 gear 1014 rotates left and right through the No. 1 rotating rod 1029, the No. 2 gear 109, the No. 2 rotating rod 1030, and the No. 1 gear 108, and then drives the No. 2 and a half gears 105 to rotate left and right, so that the two pipe mounting rods 107 can continuously swing, and the fertilizer pipe 1017 can be swung to realize the swing spraying of the fertilizer liquid, and the control valve 1018 is used to control the opening and closing of the fertilizer spraying.

[0026] Therefore, the device does not need to design an additional water pump or an electrical water pump. It only needs to utilize the additional power of the dual-axis motor 4. It can not only continuously pressurize the fertilizer storage box 2 to facilitate the spraying of fertilizer, but also make the sprayed fertilizer swing-sprayed, making the spraying more uniform and comprehensive.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
