[0048] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0049] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0050] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0051] The following describes in detail the overall structure, working principle, and technical effects of the aircraft 010 provided by this utility model, as well as the detailed steps, implementation principles, and technical effects of the accompanying aircraft 010 dispersal method, through embodiments and in conjunction with the accompanying drawings.

[0052] Please refer to Figures 1-3 The aircraft 010 provided by this utility model is used for spreading materials, and it can perform precise positioning and delivery as well as variable spreading.

[0053] Please refer to Figures 1-3 The present invention proposes an aircraft 010, comprising:

[0054] Material bin 200 is located inside aircraft 010 and is used to hold materials;

[0055] The spreading component 400 has a spreading channel 401 that runs through the spreading component 400 along the flight direction of the aircraft 010. The spreading channel 401 is connected to the material box 200. The feeding amount of the spreading component 400 is adjustable.

[0056] Aircraft 010 generates airflow during flight, and the dispersing channel 401 disperses materials under the action of the airflow.

[0057] The feed rate of the spreading component 400 is adjustable, which means that the feed rate of the spreading component 400 can be adjusted from zero to the maximum output.

[0058] It is understandable that when the aircraft 010 is in flight, it will generate airflow, which enters the spreading channel 401. Adjusting the feed rate of the spreading component 400 allows the material to fall from the material box 200 into the spreading channel 401 under the action of gravity, and the material is spread outward from the spreading channel 401 under the action of airflow.

[0059] As can be seen from the above, compared with agricultural drones and manned fixed-wing aircraft, this application, by setting a material bin 200 and a spreading component 400 inside the aircraft 010, enables the spreading channel 401 to spread materials under the action of the airflow generated by the aircraft 010. Firstly, it can meet the spreading requirements of different spreading distances, different spreading heights, and different material loads, making the spreading operation more accurate and reliable. Secondly, the feeding amount of the spreading component 400 is adjustable, and the material spreading amount of the spreading component 400 can be adjusted according to the actual positioning requirements, thereby achieving precise positioning delivery and variable spreading. Thirdly, by setting the material bin 200 inside the aircraft 010, the flight drag of the aircraft 010 can also be reduced, improving flight stability and safety.

[0060] In this embodiment, the aircraft 010 has a first direction X, a second direction Z, and a third direction Y that are perpendicular to each other.

[0061] In this embodiment, the aircraft 010 includes the fuselage 100.

[0062] In this embodiment, please refer to Figures 1-3 The aircraft 010 also includes a body 100, which is arranged along a first direction X; the body 100 is provided with a feeding port 101 and an installation port along a second direction Z, the feeding port 101 being located at the top of the body 100 and the installation port being located at the bottom of the body 100.

[0063] In this embodiment, the aircraft 010 is a fixed-wing aircraft with a propeller assembly 120 at the nose. Therefore, the aircraft 010 also includes a wing 110, a propeller assembly 120, and a tail 130. The wings 110 are arranged on opposite sides of the fuselage 100 along a third direction Y. The propeller assembly 120 is located at the nose of the fuselage 100 along a first direction X. The tail 130 is located at the tail of the fuselage 100 along a first direction X.

[0064] The aircraft 010 also includes a front landing wheel 140 and a rear landing wheel 150. The front landing wheel 140 and the rear landing wheel 150 are located at the bottom of the fuselage 100. The front landing wheel 140 is located in front of the wing 110, and the rear landing wheel 150 is located opposite the tail 130.

[0065] Understandably, the propeller assembly 120 located at the head serves as the main lift source for the aircraft 010. When the propeller assembly 120 is working, the propeller assembly 120 at the head of the fuselage 100 rotates. The rotating propeller assembly 120 generates a rearward airflow, thereby providing thrust. The fuselage 100 slides on the track via the front landing wheel 140 and the rear landing wheel 150 at the bottom. When the airflow generated by the propeller assembly 120 at the front of the fuselage 100 meets the takeoff requirements, the wings 110 on both sides of the fuselage 100 generate the main lift, so that the aircraft 010 is in flight.

[0066] It is understandable that the material guiding assembly 300 and the spreading assembly 400 are located behind the propeller assembly 120. When the aircraft 010 is in flight, the propeller assembly 120 generates airflow, and the airflow enters the spreading channel 401 from the air guide channel 312 along the first direction X, so that the spreading channel 401 spreads materials under the action of the airflow generated by the propeller assembly 120.

[0067] As can be seen from the above, the aircraft 010 designed in this way can work with the propeller assembly 120 to optimize the airflow direction and ensure uniform material dispersion. At the same time, the high-speed airflow generated by the propeller assembly 120 can accelerate material spreading, improve spreading efficiency, and increase spreading distance. Furthermore, the high-speed airflow can assist diffusion and reduce material accumulation in the spreading channel 401.

[0068] In this embodiment, please refer to Figure 3 The material box 200 is located inside the machine body 100 and is connected to the feeding port 101 and the installation port respectively.

[0069] In this embodiment, please refer to Figures 2-3 The material guiding component 300 and the spreading component 400 are disposed outside the body 100 and located at the bottom of the body 100. The material guiding component 300 is connected to the body 100 relative to the mounting port and communicates with the mounting port. The spreading component 400 is disposed along the first direction X. One end of the spreading component is connected to the material guiding component 300, and the other end is connected to the body 100 through a connector.

[0070] It is understandable that by placing the material bin 200 inside the aircraft 010, the flight drag of the aircraft 010 can be reduced, thereby improving flight stability and safety. By placing the material guiding component 300 and the spreading component 400 at the bottom of the fuselage 100, the material guiding component 300 and the spreading component 400 can work in conjunction with the airflow generated by the propeller component 120 to spread the material in the spreading channel 401.

[0071] Optionally, the material guide housing 310 of the material guide assembly 300 is fixedly connected to the bottom of the machine body 100 through multiple mounting parts.

[0072] Alternatively, please refer to Figure 3 and Figure 4 One end of the spreading shell 410 is fixedly connected to the material guiding shell 310 by welding or other means, and the other end of the spreading shell 410 is fixedly connected to the bottom of the machine body 100 by multiple second mounting rods 430.

[0073] In this embodiment, the aircraft 010 includes a feed bin 200.

[0074] The material bin 200 is used to hold materials; the materials can be powders or granules.

[0075] Optionally, granular materials can be seeds, fertilizers, etc., and powdered materials can be fire extinguishing agents, pesticide powders, etc.

[0076] In this embodiment, please refer to Figure 3 The material box 200 is located inside the machine body 100, specifically at the abdominal position of the machine body 100.

[0077] Alternatively, please refer to Figures 3-5 The machine body 100 includes multiple partitions and a skin. Multiple partitions are spaced apart along a first direction X and fixed by stringers and beams. The skin surrounds the multiple partitions by riveting or other means. The machine body 100 located in the abdomen includes a first partition 102 and a second partition 103. The top of the material box 200 along the second direction Z is fixedly connected to the first partition 102 and the second partition 103 by multiple first mounting rods 220. The bottom of the material box 200 along the second direction Z is fixedly connected to the bottom of the first partition 102 and the bottom of the second partition 103 by welding, connectors, or other means.

[0078] Among them, the bottom of the material box 200 penetrates the mounting port at the bottom of the machine body 100 along the second direction Z.

[0079] In this embodiment, the material box 200 is provided with a receiving cavity for containing materials, and a feeding pipe 210 is provided on the top of the material box 200. One end of the feeding pipe 210 is connected to the receiving cavity of the material box 200, and the other end is fixed to the machine body 100 and connected to the feeding port 101.

[0080] Optionally, the number of feeding pipes 210 includes at least two, and can be two, three, or other quantities; at the same time, the machine body 100 can be provided with feeding ports 101 corresponding to the number of feeding pipes 210.

[0081] It is understandable that the material bin 200 can be replenished with materials through the feeding port 101 set on the machine body 100, which is convenient, quick and easy to operate.

[0082] In one optional embodiment, the feeding pipe 210 includes two pipes, namely a first feeding pipe 210 and a second feeding pipe 210; the feeding port 101 includes two ports, namely a first feeding port 101 and a second feeding port 101; the material box 200 is provided with a first receiving cavity for receiving the first material and a second receiving cavity for receiving the second material, the first feeding pipe 210 connects the first receiving cavity and the first feeding port 101, and the second feeding pipe 210 connects the second receiving cavity and the second feeding port 101.

[0083] The first material and the second material are two different materials.

[0084] Understandably, the first and second materials are respectively loaded into the material bins 200, and under the influence of gravity, they enter the material guiding assembly 300. After being mixed in the material guiding assembly 300, they enter the spreading channel 401 through the air guide channel 312 for spreading. The material bins 200 designed in this way can hold two different materials and can adapt to materials that require mixing, such as fertilizers and seeds with precise ratios.

[0085] In this embodiment, the aircraft 010 also includes a material guiding assembly 300.

[0086] In this embodiment, please refer to Figure 4 , Figure 6 and Figure 8 The material guiding assembly 300 includes a material guiding shell 310 and a material guiding structure 320. The material guiding shell 310 of the material guiding assembly 300 has a material guiding channel 311 and an air guiding channel 312 extending in a third direction (Y). One end of the material guiding channel 311 is connected to the material box 200, and the other end is connected to the air guiding channel 312. The air guiding channel 312 is connected to the spreading channel 401. The material guiding structure 320 is also provided within the material guiding channel 311 of the material guiding assembly 300. The material guiding structure 320 is used to convey material to the air guiding channel 312 along the extending direction of the material guiding channel 311.

[0087] Understandably, the material enters the material guiding channel 311 of the material guiding assembly 300 from the hopper under the action of gravity. The material guiding structure 320 stirs the material in the material guiding channel 311 and conveys the material entering the material guiding channel 311 from the inlet 313 of the material guiding shell 310 to the air guiding channel 312 so that the airflow can convey the material in the air guiding channel 312 to the spreading channel 401 of the spreading assembly 400.

[0088] In this embodiment, please refer to Figure 6 and Figure 8 The material guide housing 310 is provided with an inlet 313, an air inlet 314 and an air outlet that are connected to the material guide channel 311. The inlet 313, the air inlet 314 and the air outlet are respectively located on three adjacent sides of the material guide housing 310. The inlet 313 is located on the top of the material guide housing 310 along the second direction Z. One end of the inlet 313 is connected to the material box 200 and the other end is connected to the material guide channel 311.

[0089] The air inlet 314 and the air outlet are disposed on opposite sides of the material guide housing 310 along the first direction X. The air inlet 314 and the air outlet are located on opposite sides of the air guide channel 312 along the first direction X. The air outlet is connected to the spreading channel 401.

[0090] Understandably, the airflow enters the air guide channel 312 from the air inlet 314, and spreads the material in the air guide channel 312 from the air outlet into multiple spreading channels 401; furthermore, the material in the spreading channels 401 is spread outward under the action of the airflow.

[0091] In this embodiment, please refer to Figure 8 and Figure 9 The material guiding structure 320 includes a material guiding component 321 and a material guiding drive component 322. The material guiding component 321 is located inside the material guiding channel 311 and extends through the material guiding housing 310 along the extension direction of the material guiding channel 311. The material guiding component 321 is used to stir the material and convey the material to the air guiding channel 312 along the extension direction of the material guiding channel 311. The material guiding drive component 322 is located outside the material guiding housing 310 and is connected to the material guiding housing 310. The output end of the material guiding drive component 322 is connected to the material guiding component 321 in a transmission manner so that the material guiding component 321 is rotatably arranged along the extension direction of the material guiding channel 311.

[0092] Optionally, the material guide drive 322 can be a screw motor.

[0093] In this embodiment, the material guiding assembly 300 includes a material guiding housing 310. The material guiding housing 310 has an inlet 313 relative to the material box 200. The inlet 313 connects the material box 200 and the material guiding channel 311. The diameter of the material guiding channel 311 is larger than the diameter of the inlet 313.

[0094] The entrance 313 can be a circular entrance or a rectangular entrance.

[0095] In this embodiment, please refer to Figure 8 and Figure 9 The guide component 321 includes a guide shaft 3211, a first helical blade 3212, and a second helical blade 3213. The first helical blade 3212 is arranged around the guide shaft in a first rotation direction, and the second helical blade 3213 is arranged around the guide shaft in a second rotation direction. The first rotation direction and the second rotation direction are opposite to each other. The connection between the first helical blade 3212 and the second helical blade 3213 is arranged relative to the inlet 313.

[0096] The connection point between the first helical blade 3212 and the second helical blade 3213 is the midpoint of the guide shaft 3211.

[0097] Understandably, material enters the guide channel 311 from the inlet 313. The drive unit drives the guide shaft 3211 to rotate, causing the guide shaft 3211 to convey material to opposite sides in the Y direction. The first spiral blade 3212 conveys material to one side of the drive unit, while the second spiral blade 3213 conveys material to the side away from the drive unit. This evenly distributes the material, which enters the guide channel 311 from the inlet 313, along the guide member 321 into the guide channel 311. This ensures that the material is evenly distributed and can be evenly dispersed from the guide channel 311 into the air guide channel 312, thereby improving the uniformity of material distribution. Simultaneously, the guide member 321 can stir, distribute, or mix the material, preventing clumping.

[0098] In this embodiment, the opening of the material guide channel 311 is adjustable so that the feed rate of the spreading component 400 is adjustable. It can be understood that if the opening of the material guide channel 311 is adjustable, then the feed rate of the material entering the spreading component 400 from the material guide channel 311 into the air guide channel 312 is adjustable.

[0099] In this embodiment, please refer to Figures 6-8 The spreading component 400 includes an adjustment structure 330, which includes a drive component 331 and an adjustment plate 332. The adjustment plate 332 extends along the extension direction of the material guide channel 311 and is movably disposed between the material guide channel 311 and the air guide channel 312 in the first direction X, so that the adjustment plate 332 adjusts the opening of the material guide channel 311.

[0100] It is understood that the adjusting plate 332 is movably disposed between the material guide channel 311 and the air guide channel 312 along the first direction X; wherein, the adjusting plate 332 can completely close the material guide channel 311; wherein, the adjusting plate 332 can completely open the material guide channel 311; wherein, the adjusting plate 332 can partially open the material guide channel 311; thereby achieving precise control of the opening degree of the material guide channel 311 by the adjusting plate 332. Therefore, when the aircraft 010 has not flown to the target position, the adjusting plate 332 completely closes the material guide channel 311; when the aircraft 010 flies to the target position, the adjusting plate 332 can be controlled to open all or part of the material guide channel 311, thereby achieving precise positioning delivery and variable seeding.

[0101] Alternatively, please refer to Figure 7 A mating opening extending in the third direction Y is provided on one side wall of the material guide housing 310 facing the dispensing component 400. An adjusting piece 332 is movably disposed between the material guide channel 311 and the air guide channel 312, passing through the mating opening and along the first direction X. Sliding grooves for the adjusting piece 332 are also provided on the opposite inner walls of the material guide housing 310 along the first direction X. This arrangement ensures smooth movement of the adjusting piece 332.

[0102] Alternatively, please refer to Figures 6-8 The drive assembly 331 includes an adjustment drive component 3311 and an adjustment link 3312. The adjustment drive component 3311 is fixed to the top of the spreading housing 410. The output end of the adjustment drive component 3311 is connected to the adjustment link 3312. The adjustment link 3312 is connected to the adjustment plate 332. The adjustment drive component 3311 is used to drive the adjustment link 3312 to drive the adjustment plate 332 to be movably disposed between the material guide channel 311 and the air guide channel 312 along the first direction X.

[0103] Among them, the adjustment drive component 3311 can be a servo motor.

[0104] In this embodiment, the adjustment structure 330 performs linkage control on the guide component 321, and the adjustment structure 330 is also used to control the opening and closing of the guide structure 320.

[0105] Please refer to the following when implementing this in this city. Figure 7 The outer wall of the material guide housing 310 is provided with a trigger switch 323. The trigger switch 323 is electrically connected to the material guide drive 322 of the material guide structure 320. The trigger switch 323 is used to control the opening and closing of the material guide drive 322 of the material guide structure 320.

[0106] In this embodiment, please refer to Figure 7 One end of the adjusting piece 332 is provided with a limiting part 333. The limiting part 333 is limited to the material guiding assembly 300 and is limited to the outside of the material guiding housing 310. The limiting part 333 is provided with a trigger part 334. When the adjusting piece 332 moves along the first direction X toward the material guiding housing 310 of the material guiding assembly 300, the adjusting piece 332 closes the material guiding channel 311, and the trigger part 334 contacts the trigger switch 323 to control the material guiding drive member 322 of the material guiding structure 320 to close.

[0107] The triggering part 334 can be a screw structure fixed on the limiting part 333.

[0108] Understandably, when the adjustment drive 3311 moves away from the material guide housing 310 along the first direction X, the adjustment plate 332 gradually opens the material guide channel 311, and the trigger part 334 disengages from the trigger switch 323 to control the material guide 321 to open; when the material guide 321 is open, the material is evenly stirred and transported to the air guide channel 312 along the extension direction of the material guide channel 311.

[0109] When the adjustment drive 3311 moves along the first direction X toward the material guide housing 310, the adjustment piece 332 gradually closes the material guide channel 311, and the trigger part 334 contacts the trigger switch 323 to control the material guide 321 to close; when the material guide 321 closes, the spreading task is completed.

[0110] Therefore, by linking the opening and closing of the material guiding channel 311 with the opening and closing of the material guiding structure 320 through the adjustment structure 330, the adjustment structure 330 can be controlled by ground remote control or GPS flight control, thus realizing the seeding operation and giving the aircraft 010 the characteristics of high efficiency, environmental protection, intelligence and simple operation.

[0111] In this embodiment, the aircraft 010 includes a dispersing assembly 400.

[0112] The spreading component 400 is used to spread materials.

[0113] In this embodiment, please refer to Figure 4 , Figure 6 and Figure 8 The spreading component 400 is provided with a plurality of spreading channels 401 arranged along the first direction X, and one end of the plurality of spreading channels 401 is connected to the air outlet; the aircraft 010 generates airflow in flight state, and the airflow enters the spreading channel 401 along the air guide channel 312 so that the spreading channel 401 spreads materials under the action of the airflow.

[0114] In this embodiment, please refer to Figure 4 , Figure 6 and Figure 8 The spreading component 400 includes a housing and a partition 420. The housing has a channel, and the partition 420 is disposed in the channel to divide the channel into multiple spreading channels 401. The housing has an inlet and an outlet communicating with the channel on opposite sides. Along the extension direction from the inlet to the outlet, the channel spreads out in a fan shape to both sides.

[0115] Understandably, the spreading component 400 is provided with a fan-shaped spreading channel, which can increase the spreading surface of the material and increase the coverage area of ​​the material spread from the spreading channel 401.

[0116] In this embodiment, the aircraft 010 also includes a control module, which is communicatively connected to the adjustment structure 330. By linking the adjustment structure 330 with the guide component 321, the aircraft 010 can control the adjustment structure 330 via ground remote control or GPS flight control, thus realizing the entire seeding operation process.

[0117] The working principle and process of the aircraft 010 provided in this embodiment of the utility model are as follows:

[0118] Material is added to the material box 200 through the feeding port 101 on the machine body 100.

[0119] The control system controls the adjustment structure 330 to adjust the opening of the material guide channel 311. The adjustment drive 3311 adjusts the position of the adjustment piece 332 in the first direction X according to the requirements. At this time, while the adjustment drive 3311 is moving away from the material guide housing 310 along the first direction X, the adjustment piece 332 gradually opens the material guide channel 311, the trigger part 334 disengages from the trigger switch 323, and the material guide drive 322 is activated. Further, the material guide drive 322 drives the material guide 321 to rotate, and the material guide 321 uniformly stirs and transports the material along the extension direction of the material guide channel 311 into the air guide channel 312. Further, the material located in the air guide channel 312 is dispersed and spread out from the multiple spreading channels 401 under the action of the airflow of the propeller assembly 120.

[0120] After the seeding task is completed, the control system closes the material guide channel 311 by adjusting the structure 330. At this time, while the adjusting drive 3311 is moving along the first direction X toward the material guide housing 310, the adjusting plate 332 gradually closes the material guide channel 311, the trigger part 334 contacts the trigger switch 323, and the material guide drive 322 is turned off. The material guide drive 322 stops driving the material guide 321 to rotate. The seeding task is then completed, and the aircraft 010 returns to base.

[0121] In summary, the aircraft 010 provided in this embodiment of the present invention, by setting a material bin 200 and a spreading component 400 inside the aircraft 010, enables the spreading channel 401 to spread materials under the action of the airflow generated by the aircraft 010. Firstly, it can meet the spreading requirements of different spreading distances, different spreading heights, and different material loads, making the spreading operation more accurate and reliable. Secondly, the feeding amount of the spreading component 400 is adjustable, allowing the material spreading amount to be adjusted according to actual positioning requirements, thereby achieving precise positioning and delivery as well as variable spreading. Thirdly, by placing the material bin 200 inside the aircraft 010, the flight drag of the aircraft 010 is reduced, improving flight stability and safety.

[0122] Furthermore, the aircraft 010 is a fixed-wing aircraft 010 with a propeller assembly 120 installed at the nose of the fuselage 100; with this design, the dispersing assembly 400 can work with the propeller assembly 120 to optimize the airflow direction and ensure uniform material dispersion; at the same time, the high-speed airflow generated by the propeller assembly 120 can accelerate material dispersal, improve dispersal efficiency, and increase dispersal distance; furthermore, the high-speed airflow can assist diffusion and reduce material accumulation in the dispersal channel 401.

[0123] Furthermore, by linking the opening and closing of the material guiding channel 311 with the opening and closing of the material guiding structure 320 through the adjustment structure 330, the adjustment structure 330 can be controlled by ground remote control or GPS flight control, thereby realizing the seeding operation and giving the aircraft 010 the characteristics of high efficiency, environmental protection, intelligence and simple operation.
