It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0051] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0052] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0053] The overall structure, working principle and technical effects of the aircraft 010 provided by the present invention, as well as the detailed steps, implementation principle and technical effects of the matching spreading method of the aircraft 010 are described in detail below through embodiments and in combination with the accompanying drawings.

[0054] Please refer to Figure 1-Figure 3 The aircraft 010 provided by the present invention is used for spreading materials, and it can perform precise positioning delivery and variable spreading.

[0055] Please refer to Figure 1-Figure 3 The present invention provides an aircraft 010, comprising:

[0056] A material box 200 is located inside the aircraft 010 and is used to store materials;

[0057] The spreading assembly 400 is provided with a spreading channel 401 which passes through the spreading assembly 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 assembly 400 is adjustable.

[0058] The aircraft 010 generates airflow in flight, and the spreading channel 401 spreads materials under the action of the airflow.

[0059] The feed rate of the spreading assembly 400 is adjustable, which can be understood as the feed rate of the spreading assembly 400 being adjustable from zero to a maximum output.

[0060] It is understandable that when the aircraft 010 is in flight, the aircraft 010 will generate airflow, and the airflow will enter the sowing channel 401; the feed amount of the sowing component 400 is adjusted so that the material can fall from the material box 200 into the sowing channel 401 under the action of gravity, and the material is sown from the inside of the sowing channel 401 to the outside under the action of the airflow.

[0061] As can be seen from the above, compared with plant protection drones and manned fixed-wing aircraft; this application arranges a material box 200 and a sowing component 400 in the aircraft 010, so that the sowing channel 401 can sow materials under the action of the airflow generated by the aircraft 010; on the one hand, it can meet the sowing requirements of different sowing distances, different sowing heights and different material loads, making the sowing operation more accurate and reliable; on the other hand, the feed amount of the sowing component 400 is adjustable, and the material sowing amount of the sowing component 400 can be adjusted according to the actual positioning requirements, so as to achieve precise positioning delivery and variable sowing; on the third hand, by arranging the material box 200 inside the aircraft 010, the flight resistance of the aircraft 010 can also be reduced, thereby improving the flight stability and safety.

[0062] 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.

[0063] In this embodiment, aircraft 010 includes an airframe 100 .

[0064] In this embodiment, please refer to Figure 1-Figure 3 The aircraft 010 further includes a fuselage 100 , which is arranged along a first direction X. The fuselage 100 is provided with a feeding port 101 and an installation port along a second direction Z. The feeding port 101 is located at the top of the fuselage 100 , and the installation port is located at the bottom of the fuselage 100 .

[0065] In this embodiment, aircraft 010 is a fixed-wing aircraft with a propeller assembly 120 at its head. Therefore, aircraft 010 also includes wings 110, propeller assembly 120, and tail 130. Wings 110 are arranged on opposite sides of the fuselage 100 along the third direction Y; propeller assembly 120 is located at the head of the fuselage 100 along the first direction X; and tail 130 is located at the tail of the fuselage 100 along the first direction X.

[0066] Among them, 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 arranged 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 relatively in the tail 130 part.

[0067] It can be understood that the propeller assembly 120 located at the head serves as the main lift source of the aircraft 010. When the propeller assembly 120 is working, the propeller assembly 120 at the head of the fuselage 100 rotates. The propeller assembly 120 in the rotating state will generate a backward airflow, thereby providing thrust; the fuselage 100 slides on the track through the front landing wheels 140 and the rear landing wheels 150 at the bottom. When the propeller assembly 120 at the front end of the fuselage 100 generates airflow that meets the take-off requirements, the wings 110 on both sides of the fuselage 100 generate the main lift to keep the aircraft 010 in a flying state.

[0068] It can be understood that the material guide assembly 300 and the sowing 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 sowing channel 401 from the air guide channel 312 along the first direction X, so that the sowing channel 401 spreads materials under the action of the airflow generated by the propeller assembly 120.

[0069] As can be seen from the above, the aircraft 010 designed in this way can cooperate with the propeller assembly 120 to optimize the airflow direction and ensure uniform dispersion of materials; at the same time, by utilizing the high-speed airflow generated by the propeller assembly 120, the material spreading can be accelerated, the spreading efficiency can be improved, and the spreading distance can be increased; further, the high-speed airflow can assist diffusion and reduce the accumulation of materials in the spreading channel 401.

[0070] In this embodiment, please refer to Figure 3 The material box 200 is arranged inside the body 100, and the material box 200 is communicated with the feeding port 101 and the installation port respectively.

[0071] In this embodiment, please refer to Figure 2-Figure 3 The material guiding assembly 300 and the spreading assembly 400 are arranged outside the body 100 and located at the bottom of the body 100. The material guiding assembly 300 is connected to the body 100 relative to the mounting port, and the material guiding assembly 300 is communicated with the mounting port; the spreading assembly 400 is arranged along the first direction X, one end of the spreading assembly is connected to the material guiding assembly 300, and the other end is connected to the body 100 through a connecting member.

[0072] It can be understood that by arranging the material box 200 inside the aircraft 010, the flight resistance of the aircraft 010 can be reduced, and the flight stability and safety can be improved; by arranging the material guide component 300 and the sowing component 400 at the bottom of the body 100, the material guide component 300 and the sowing component 400 can cooperate with the airflow generated by the propeller component 120 to realize the sowing of the material in the sowing channel 401.

[0073] Optionally, the material guiding shell 310 of the material guiding assembly 300 is fixedly connected to the bottom of the body 100 through a plurality of mounting parts.

[0074] Alternatively, see Figure 3 and Figure 4 One end of the spreading shell 410 is fixedly connected to the material guide shell 310 by welding or the like, and the other end of the spreading shell 410 is fixedly connected to the bottom of the body 100 by a plurality of second mounting rods 430 .

[0075] In this embodiment, aircraft 010 includes a tank 200 .

[0076] The material box 200 is used to contain materials; the materials can be powders and granular materials.

[0077] Optionally, the granular material may be seeds, fertilizers, etc., and the powder material may be fire extinguishing agent, pesticide powder, etc.

[0078] In this embodiment, please refer to Figure 3 The material box 200 is arranged inside the body 100, and the material box 200 is arranged at the abdomen position of the body 100.

[0079] Alternatively, see Figure 3-Figure 5 The fuselage 100 includes multiple bulkheads and a skin. Multiple bulkheads are spaced apart along a first direction X and secured by girders and beams. The skin surrounds the multiple bulkheads by riveting or other means. The fuselage 100 located at the belly portion includes a first bulkhead 102 and a second bulkhead 103. The top of the container 200 along the second direction Z is fixedly connected to the first and second bulkheads 102, 103, respectively, via multiple first mounting rods 220. The bottom of the container 200 along the second direction Z is fixedly connected to the bottoms of the first and second bulkheads 102, 103, respectively, via welding or connectors.

[0080] The bottom of the material box 200 along the second direction Z passes through the installation opening at the bottom of the body 100 .

[0081] In this embodiment, a accommodating cavity for accommodating materials is provided in the material box 200, 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 accommodating cavity of the material box 200, and the other end is fixed to the body 100 and connected to the feeding port 101.

[0082] Optionally, the number of the feeding tubes 210 includes at least two, and may be two, three, or the like; meanwhile, the machine body 100 is provided with the feeding ports 101 corresponding to the number of the feeding tubes 210 .

[0083] It is understandable that the material box 200 can be replenished with materials through the feeding port 101 provided on the machine body 100, which is convenient, fast and easy to operate.

[0084] In an optional embodiment, the feeding pipes 210 include two, which are respectively the first feeding pipe 210 and the second feeding pipe 210; the feeding ports 101 include two, which are respectively the first feeding port 101 and the second feeding port 101; the material box 200 is provided with a first accommodating cavity for accommodating the first material and a second accommodating cavity for accommodating the second material, the first feeding pipe 210 connects the first accommodating cavity and the first feeding port 101, and the second feeding pipe 210 connects the second accommodating cavity and the second feeding port 101.

[0085] The first material and the second material are two different materials.

[0086] It is understood that the first material and the second material are separately loaded into the material bin 200, enter the material guide assembly 300 under the action of gravity, are mixed in the material guide assembly 300, and then enter the sowing channel 401 through the air guide channel 312 for sowing. The material bin 200 designed in this way can accommodate two different materials and can adapt to materials that require mixing, such as fertilizer and seeds with a precise ratio.

[0087] In this embodiment, the aircraft 010 further includes a material guide assembly 300 .

[0088] In this embodiment, please refer to Figure 4 、 Figure 6 and Figure 8 The material guide assembly 300 includes a material guide housing 310 and a material guide structure 320. The material guide housing 310 of the material guide assembly 300 includes a material guide channel 311 and an air guide channel 312 extending along the third direction Y. One end of the material guide channel 311 communicates with the material bin 200, and the other end communicates with the air guide channel 312. The air guide channel 312 communicates with the spreading channel 401. The material guide channel 311 of the material guide assembly 300 also includes a material guide structure 320. The material guide structure 320 is used to transport material toward the air guide channel 312 along the direction in which the material guide channel 311 extends.

[0089] It can be understood that the material enters the material guide channel 311 in the material guide assembly 300 from the material silo under the action of gravity, the material guide structure 320 stirs the material in the material guide channel 311, and the material entering the material guide channel 311 from the inlet 313 of the material guide shell 310 is evenly transported to the air guide channel 312; so that the airflow transports the material in the air guide channel 312 to the sowing channel 401 of the sowing assembly 400.

[0090] In this embodiment, please refer to Figure 6 and Figure 8 The material guiding shell 310 is provided with an inlet 313, an air inlet 314 and an air outlet which are connected to the material guiding channel 311. The inlet 313, the air inlet 314 and the air outlet are respectively located on three adjacent sides of the material guiding shell 310; the inlet 313 is arranged at the top of the material guiding shell 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 guiding channel 311.

[0091] The air inlet 314 and the air outlet are arranged on opposite sides of the material guide housing 310 along the first direction X, and the air inlet 314 and the air outlet are located on opposite sides of the air guide channel 312 along the first direction X, and the air outlet is connected to the sowing channel 401.

[0092] It is understandable that 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 to the multiple spreading channels 401; further, the material in the spreading channel 401 is spread outward under the action of the airflow.

[0093] In this embodiment, please refer to Figure 8 and Figure 9 The material guide structure 320 includes a material guide member 321 and a material guide driving member 322. The material guide member 321 is located in the material guide channel 311 and passes through the material guide shell 310 along the extension direction of the material guide channel 311. The material guide member 321 is used to stir the material and transport the material to the air guide channel 312 along the extension direction of the material guide channel 311; the material guide driving member 322 is located outside the material guide shell 310 and is connected to the material guide shell 310. The output end of the material guide driving member 322 is transmission-connected to the material guide member 321 so that the material guide member 321 is rotated along the extension direction of the material guide channel 311.

[0094] Optionally, the material guide driving member 322 may be a screw motor.

[0095] In this embodiment, the material guiding assembly 300 includes a material guiding housing 310 . The material guiding housing 310 is provided with an inlet 313 relative to the material box 200 . The inlet 313 connects the material box 200 with a material guiding channel 311 . The diameter of the material guiding channel 311 is larger than the diameter of the inlet 313 .

[0096] The inlet 313 may be a circular inlet or a rectangular inlet.

[0097] In this embodiment, please refer to Figure 8 and Figure 9 The material guide member 321 includes a material guide shaft 3211 and a first spiral blade 3212 and a second spiral blade 3213. The first spiral blade 3212 is arranged around the material guide shaft along a first rotation direction, and the second spiral blade 3213 is arranged around the material guide shaft along a second rotation direction. The first rotation direction and the second rotation direction are opposite to each other, and the connection between the first spiral blade 3212 and the second spiral blade 3213 is arranged relative to the inlet 313.

[0098] The connection point between the first spiral blade 3212 and the second spiral blade 3213 is the midpoint of the material guide shaft 3211 .

[0099] As can be understood, material enters the material guide channel 311 from the inlet 313, and the drive member drives the material guide shaft 3211 to rotate, causing the material guide shaft 3211 to transport the material toward opposite sides in the third direction Y. The first spiral blade 3212 transports the material toward the drive member, while the second spiral blade 3213 transports the material away from the drive member. The material entering the material guide channel 311 from the inlet 313 is evenly dispersed along the material guide member 321 into the material guide channel 311. This ensures that the material is evenly distributed and evenly dispersed from the material guide channel 311 into the air guide channel 312, thereby improving the uniformity of material dissemination. Furthermore, the material guide member 321 can stir, spread, or mix the material, preventing it from clumping.

[0100] In this embodiment, the opening of the material guide channel 311 is adjustable so that the feeding amount of the spreading assembly 400 can be adjusted. It is understood that if the opening of the material guide channel 311 is adjustable, the feeding amount of the material entering the air guide channel 312 from the material guide channel 311 into the spreading assembly 400 can be adjusted.

[0101] In this embodiment, please refer to Figure 6-Figure 8 The spreading assembly 400 includes an adjustment structure 330, which includes a drive assembly 331 and an adjustment plate 332. The adjustment plate 332 extends along the extension direction of the material guide channel 311. The adjustment plate 332 is movably arranged between the material guide channel 311 and the air guide channel 312 along the first direction X so that the adjustment plate 332 adjusts the opening of the material guide channel 311.

[0102] It is understood that the adjustment piece 332 is movable along the first direction X between the material guide channel 311 and the air guide channel 312. The adjustment piece 332 can completely close the material guide channel 311, completely open the material guide channel 311, or partially open the material guide channel 311. This allows the adjustment piece 332 to precisely control the opening of the material guide channel 311. Therefore, when the aircraft 010 has not yet reached its target location, the adjustment piece 332 completely closes the material guide channel 311. When the aircraft 010 reaches its target location, the adjustment piece 332 can be controlled to open all or part of the material guide channel 311, thereby achieving precise positioning and variable-variable seeding.

[0103] Alternatively, see Figure 7 A mating opening extending along the third direction Y is provided on a side wall of the material guide housing 310 facing the spreading assembly 400. An adjustment plate 332 extends through the mating opening and is movable along the first direction X between the material guide channel 311 and the air guide channel 312. Slide grooves for the adjustment plate 332 are also provided on two opposing inner walls of the material guide housing 310 along the first direction X. It will be appreciated that this arrangement ensures smooth movement of the adjustment plate 332.

[0104] Alternatively, see Figure 6-Figure 8 The driving assembly 331 includes an adjusting driving member 3311 and an adjusting connecting rod 3312. The adjusting driving member 3311 is fixed to the top of the spreading shell 410. The output end of the adjusting driving member 3311 is transmission-connected with the adjusting connecting rod 3312. The adjusting connecting rod 3312 is connected to the adjusting piece 332. The adjusting driving member 3311 is used to drive the adjusting connecting rod 3312 to drive the adjusting piece 332 to be movably arranged along the first direction X between the material guide channel 311 and the air guide channel 312.

[0105] The adjustment drive member 3311 may be a steering gear.

[0106] In this embodiment, the adjustment structure 330 performs linkage control on the material guiding member 321 , and the adjustment structure 330 is also used to control the opening and closing of the material guiding structure 320 .

[0107] In the implementation of this city, please refer to Figure 7 A trigger switch 323 is provided on the outer wall of the material guiding shell 310 , and the trigger switch 323 is electrically connected to the material guiding driving member 322 of the material guiding structure 320 . The trigger switch 323 is used to control the opening and closing of the material guiding driving member 322 of the material guiding structure 320 .

[0108] In this embodiment, please refer to Figure 7 A limiting portion 333 is provided at one end of the adjustment piece 332, and the limiting portion 333 is limitedly connected to the material guide assembly 300 and limited to the outside of the material guide shell 310, and a trigger portion 334 is provided on the limiting portion 333; when the adjustment piece 332 moves along the first direction X toward the material guide shell 310 of the material guide assembly 300, the adjustment piece 332 closes the material guide channel 311, and the trigger portion 334 contacts the trigger switch 323 to control the material guide drive member 322 of the material guide structure 320 to be closed.

[0109] The trigger portion 334 may be a screw structure fixed on the limiting portion 333 .

[0110] It can be understood that, when the adjustment driving member 3311 moves along the first direction X toward away from the material guide shell 310, the adjustment piece 332 gradually opens the material guide channel 311, and the trigger part 334 is released from contact with the trigger switch 323 to control the material guide member 321 to open; the material guide member 321 is opened, and the material is evenly stirred and transferred to the air guide channel 312 along the extension direction of the material guide channel 311.

[0111] When the adjustment driving member 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 member 321 to close; when the material guide member 321 is closed, the sowing task is completed.

[0112] Therefore, by linking the opening and closing of the material guide channel 311 with the opening and closing of the material guide structure 320 through the adjustment structure 330, the adjustment structure 330 can be controlled by ground remote control or GPS flight control to achieve the spreading operation, making the aircraft 010 efficient, environmentally friendly, intelligent and easy to operate.

[0113] In this embodiment, aircraft 010 includes spreading assembly 400 .

[0114] The spreading assembly 400 is used for spreading materials.

[0115] In this embodiment, please refer to Figure 4 、 Figure 6 and Figure 8 The spreading assembly 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 the flight state, and the airflow enters the spreading channel 401 along the air guide channel 312, so that the spreading channel 401 spreads the material under the action of the airflow.

[0116] In this embodiment, please refer to Figure 4 、 Figure 6 and Figure 8 The spreading assembly 400 includes a shell and a spacer 420. A channel is provided in the shell, and the spacer 420 is arranged in the channel to divide the channel into multiple spreading channels 401; a feed port and a discharge port connected to the channel are provided on opposite sides of the shell; along the extension direction from the feed port to the discharge port, the channel spreads fan-shaped to both sides along the extension direction.

[0117] It is understandable that the fan-shaped diffusion channel provided in the spreading assembly 400 can increase the spreading surface of the material and increase the coverage area of ​​the material spread out from the spreading channel 401 .

[0118] In this embodiment, the aircraft 010 also includes a control module, which is communicated with the adjustment structure 330. By linking the adjustment structure 330 with the material guide 321, the aircraft 010 can control the adjustment structure 330 through ground remote control or GPS flight control, thereby realizing the entire spreading operation process.

[0119] The working principle and process of the aircraft 010 provided in the embodiment of the present invention are specifically as follows:

[0120] The material box 200 is replenished with materials from the material feeding port 101 on the machine body 100 .

[0121] The control system controls the adjustment structure 330 to adjust the opening of the material guide channel 311. The adjustment drive 3311 adjusts the opening of the material guide channel 311 as required, adjusting the position of the adjustment plate 332 in the first direction X. At this time, as the adjustment drive 3311 moves along the first direction X away from the material guide housing 310, the adjustment plate 332 gradually opens the material guide channel 311, the trigger portion 334 disengages from the trigger switch 323, and the material guide drive 322 is activated. Furthermore, the material guide drive 322 drives the material guide member 321 to rotate, which uniformly stirs the material along the extension direction of the material guide channel 311 and transfers it into the air guide channel 312. Furthermore, the material within the air guide channel 312 is dispersed and distributed through the multiple dissemination channels 401 under the influence of the airflow of the propeller assembly 120.

[0122] After the spreading task is completed, the control system closes the material guide channel 311 by adjusting the structure 330. At this time, when the adjustment drive member 3311 moves along the first direction X toward the material guide housing 310, the adjustment plate 332 gradually closes the material guide channel 311, the trigger part 334 contacts the trigger switch 323, and the material guide drive member 322 is turned off. The material guide drive member 322 stops driving the material guide member 321 to rotate. The spreading task is then completed, and the aircraft 010 returns.

[0123] In summary, the aircraft 010 provided by the embodiment of the present invention, by arranging the material box 200 and the sowing component 400 inside the aircraft 010, enables the sowing channel 401 to sow materials under the action of the airflow generated by the aircraft 010; on the one hand, it can meet the sowing requirements of different sowing distances, different sowing heights and different material loads, so that the sowing operation is more accurate and reliable; on the other hand, the feed amount of the sowing component 400 is adjustable, and the material sowing amount of the sowing component 400 can be adjusted according to the actual positioning requirements, so as to achieve precise positioning delivery and variable sowing; on the third hand, by arranging the material box 200 inside the aircraft 010, the flight resistance of the aircraft 010 can also be reduced, thereby improving the flight stability and safety.

[0124] Furthermore, the aircraft 010 is a fixed-wing aircraft 010 in which a propeller assembly 120 is provided at the head of the fuselage 100; through such a design of the aircraft 010, the spreading assembly 400 can cooperate with the propeller assembly 120 to optimize the airflow direction and ensure uniform dispersion of the material; at the same time, by utilizing the high-speed airflow generated by the propeller assembly 120, the material spreading can be accelerated, the spreading efficiency is improved, and the spreading distance is increased; further, the high-speed airflow can assist diffusion and reduce the accumulation of materials in the spreading channel 401.

[0125] Furthermore, by linking the opening and closing of the material guide channel 311 with the opening and closing of the material guide structure 320 through the adjustment structure 330, the adjustment structure 330 can be controlled by ground remote control or GPS flight control to achieve the spreading operation, making the aircraft 010 efficient, environmentally friendly, intelligent and easy to operate.
