[0043] It should be noted that the features in the embodiments of the present utility model can be combined with each other without conflict.

[0044] Currently, the load boxes adopted in the agricultural drone execution system are generally integrally formed by processes such as blow molding. However, due to their large volume and inability to be disassembled, these boxes do not have stackability, resulting in inconvenience during transportation and significantly increasing the cost burden.

[0045] Based on the above problems, the embodiments of the present utility model provide an aircraft for drones, especially applicable to the field of agricultural equipment. Sowing can be carried out through this aircraft, which is convenient, fast and efficient, significantly improving the operation efficiency.

[0046] Specifically, the aircraft includes a flight body and a material box structure. The flight body is connected to a mounting member. The material box structure can be used to load agricultural crops such as seedlings. The flight body drives the material box structure to fly and completes the spreading action through the material box structure during flight, significantly improving the agricultural operation efficiency.

[0047] Optionally, the flight body can be a rotary-wing drone, specifically a quadcopter drone. Of course, it can also be a single-rotor drone, a dual-rotor drone, a hexacopter drone, an octocopter drone, etc. The flight body can operate automatically according to a preset path, flight speed, attitude, etc., or be manually controlled by an operator.

[0048] In addition, the embodiments of the present utility model also provide a ground vehicle. The ground vehicle includes a carrier and a material box structure. The carrier is connected to the material box structure. The carrier can be an unmanned vehicle. The carrier drives the material box structure to complete the spreading action during ground travel, significantly improving the agricultural operation efficiency.

[0049] Specifically, please refer to Figures 1 to 6 , the material box structure 10 includes a mounting member 100 and a material shell 200.

[0050] Among them, the mounting member 100 is used to connect to the flight body or the carrier; the material shell 200 is detachably connected to the mounting member 100. An opening 210 is provided at the top of the material shell 200. The cross-sectional area of the opening 210 is larger than the cross-sectional area of the bottom of the material shell 200, so that at least two material shells 200 can be stacked along the opening 210 in a state where they are not connected to the mounting member 100.

[0051] In this embodiment, the material shell 200 is connected to the mounting member 100 in a separable engagement manner, so as to facilitate the separate disassembly of the mounting group and the material shell 200. Moreover, the material shell 200 and the mounting member 100 can also be made of different materials according to the usage requirements to improve the structural stability and strength of the material box structure 10. The function of the material shell 200 is to contain materials, and an opening 210 is provided at the top of the material shell 200 to facilitate the material shell 200 to contain materials. In addition, the cross-sectional area of the opening 210 of the material shell 200 is larger than the cross-sectional area of the bottom of the material shell 200, so that at least two material shells 200 can be stably stacked along the opening 210 without connecting the mounting member 100 (as shown in Figure 3 ), thereby effectively utilizing the storage space and reducing the transportation cost.

[0052] It is worth mentioning that since the mounting member 100 is connected to the flying body or the carrier, the mounting member 100 is made of a material with higher structural strength to ensure its structural strength and stability and ensure the stable flight of the aircraft. While the material shell 200 can be made of a material with relatively lower structural strength to reduce costs.

[0053] Furthermore, the mounting member 100 is detachably connected to the opening 210, which is convenient for assembly.

[0054] Specifically, the mounting member 100 is detachably connected to the outer side wall of the material shell 200.

[0055] Furthermore, the size of the material shell 200 decreases in the direction from the opening 210 towards the bottom of the material shell 200.

[0056] In this embodiment, the size of the material shell 200 gradually decreases in the direction from the opening 210 towards the bottom of the material shell 200.

[0057] The mounting member 100 is installed on the flying body or the carrier to drive the mounting member 100 and the material shell 200 to move through the flying body or the carrier, so as to facilitate material transportation. The size of the material shell 200 (which can be the length, width or height of the material shell) gradually decreases from the opening 210 downwards to the bottom direction, so as to achieve the stable stacking of multiple material shells 200 (as shown in Figure 3 ), thereby effectively utilizing the storage space and reducing the transportation cost.

[0058] As shown in Figure 3 , the size of the material shell 200 gradually decreases in the direction from the opening 210 towards the bottom of the material shell 200 to form a funnel shape.

[0059] Of course, in other embodiments of the present invention, as shown in Figure 7 , the side wall of the material shell 200 can also be a stepped structure with gradually decreasing dimensions.

[0060] Or in some other embodiments of the present invention, such as Figure 8 shown, the outer side wall of the material housing 200 is an arcuate surface structure with gradually decreasing dimensions.

[0061] It can be understood that as long as the dimensions of the material housing 200 meet the condition of decreasing along the direction from the opening 210 towards the bottom of the material housing 200, no specific limitation is made here.

[0062] Furthermore, when the mounting member 100 is connected to the opening 210, the mounting member 100 covers a part of the opening 210, and the uncovered part of the opening 210 forms the feed inlet 211 of the material housing 200.

[0063] Specifically, the mounting member 100 is connected to the middle of the opening 210 to form the feed inlets 211 on both sides of the mounting member 100, so that it is convenient to add materials through the two feed inlets 211 even when the mounting member 100 and the material housing 200 are in an assembled state.

[0064] Furthermore, the side wall of the material housing 200 is provided with a guiding structure 290, so that a plurality of material housings 200 can be stacked in a guided manner when stacked, thereby improving the stacking convenience and avoiding misaligned stacking of a plurality of material housings 200.

[0065] In this embodiment, the guiding structure 290 is in the shape of a groove or a protrusion, and the groove or the protrusion extends along the direction from the opening 210 towards the bottom of the material housing 200, so as to play a guiding role when two material housings 200 are stacked.

[0066] Furthermore, the mounting member 100 is provided with a first positioning portion 110, and the material housing 200 is provided with a second positioning portion 220.

[0067] In this embodiment, by providing the first positioning portion 110 on the mounting member 100 and the second positioning portion 220 on the material housing 200, the positioning cooperation between the first positioning portion 110 and the second positioning portion 220 facilitates the quick installation of the mounting member 100 and the material housing 200, thereby improving the assembly efficiency.

[0068] Among them, the first positioning portion 110 is a groove, and the second positioning portion 220 is a protrusion. The second positioning portion 220 can be embedded in the first positioning portion 110, so as to achieve the positioning cooperation between the first positioning portion 110 and the second positioning portion 220.

[0069] Of course, in other embodiments of the present invention, the first positioning portion 110 can also be a protrusion, and the second positioning portion 220 can also be a groove. The first positioning portion 110 can be embedded in the second positioning portion 220, and no specific limitation is made here.

[0070] Furthermore, the mounting member 100 is provided with a first mounting hole 120, and the material housing 200 is provided with a second mounting hole 230. The first mounting hole 120 and the second mounting hole 230 are correspondingly arranged, and the first mounting hole 120 and the second mounting hole 230 are used for mounting fasteners.

[0071] In this embodiment, through the positioning cooperation of the first positioning portion 110 and the second positioning portion 220, the pre-positioning of the material box structure 10 is realized. It can be understood that when the first positioning portion 110 and the second positioning portion 220 are in cooperation, the first mounting hole 120 and the second mounting hole 230 are correspondingly arranged, which facilitates the operator to sequentially pass the fastener through the first mounting hole 120 and the second mounting hole 230, thereby making the mounting member 100 and the material housing 200 firmly connected.

[0072] Optionally, the number of the first mounting holes 120 and the second mounting holes 230 is multiple. The multiple first mounting holes 120 and the multiple second mounting holes 230 are arranged in one-to-one correspondence. The fastener can be a screw or a bolt to further improve the mounting firmness.

[0073] Furthermore, the first mounting hole 120 is located in the first positioning portion 110, and the second mounting hole 230 is located in the second positioning portion 220.

[0074] In this embodiment, by arranging the first mounting hole 120 in the first positioning portion 110 and the second mounting hole 230 in the second positioning portion 220, it is convenient for the operator to install the fastener on the first positioning portion 110 and the second positioning portion 220 after the fixed cooperation of the first positioning portion 110 and the second positioning portion 220.

[0075] Optionally, the number of the first mounting holes 120 and the second mounting holes 230 is three each. The three first mounting holes 120 and the three second mounting holes 230 are arranged in one-to-one correspondence.

[0076] It should be noted that the number of the first positioning portions 110 and the second positioning portions 220 is also multiple. Specifically, at least two first positioning portions 110 are provided at both ends of the mounting member 100, and at least second positioning portions 220 are correspondingly provided on the inner wall of the material housing 200.

[0077] Furthermore, a flanging 240 away from the opening direction is provided at the top edge of the material housing 200.

[0078] In this embodiment, by providing the flanging 240 structure at the top edge of the material housing 200, the structural strength and structural stability of the material housing 200 are improved, so that the opening 210 of the material housing 200 is not easily deformed; in addition, when multiple material housings 200 are in a stacked state, the flanging 240 structure also facilitates the operator to lift the flanging 240 structure, thereby facilitating the splitting of multiple material housings 200.

[0079] Furthermore, the material housing 200 is further provided with a plurality of support ribs 250. The plurality of support ribs 250 are spaced apart, and the plurality of support ribs 250 are all connected to the flanging 240 and extend along the direction of the opening towards the bottom of the material housing 200.

[0080] In this embodiment, by providing a plurality of support ribs 250 spaced apart on the material housing 200 and connecting the support ribs 250 to the flanging 240, the structural stability and structural strength of the material housing 200 are further improved.

[0081] Furthermore, the material housing 200 is further provided with a reinforcing structure 260. The reinforcing structure 260 is recessed on the outer sidewall of the material housing 200 and extends along the direction of the opening towards the bottom of the material housing 200.

[0082] In this embodiment, by providing the recessed reinforcing structure 260 on the material housing 200, the structural stability and structural strength of the material housing 200 are further improved, thereby improving the ability of the material housing 200 to load materials.

[0083] Optionally, at least two sidewalls of the material housing 200 are provided with reinforcing mechanisms.

[0084] Furthermore, the mounting member 100 is provided with a first lapping portion 130, and the top edge of the material housing 200 is provided with a second lapping portion 270. The first lapping portion 130 includes a limiting portion 131 and a cover edge 132 connected to each other. The limiting portion 131 abuts against the inner wall of the second lapping portion 270, and the cover edge 132 abuts against the top edge of the second lapping portion 270.

[0085] In this embodiment, by the limiting portion 131 abutting against the inner wall of the second lapping portion 270 and the cover edge 132 abutting against the top edge of the second lapping portion 270, it is convenient for the mounting member 100 to be assembled with the material housing 200, and the structural strength and structural stability during the assembly of the mounting member 100 and the material housing 200 can be improved.

[0086] Furthermore, a discharge port 280 is provided at the bottom of the material housing 200, and the discharge port 280 is used for installing a broadcaster.

[0087] In this embodiment, by providing the discharge port 280 for installing a broadcaster at the bottom of the material housing 200, it is convenient for the material to be broadcast out of the material housing 200 through the broadcaster; in addition, when a plurality of material housings 200 are in a stacked state, due to the existence of the discharge port 280, a sealed space between two adjacent material housings 200 can be avoided, that is, a negative pressure phenomenon between two adjacent material housings 200 can be avoided, thereby causing difficulty in separating the material housings 200.

[0088] In summary, the embodiment of the present utility model provides a bin structure 10 and an aircraft. The mounting member 100 is installed on the aircraft body to drive the mounting member 100 and the bin to fly through the aircraft body, thereby facilitating the transportation of materials. The material shell 200 is connected to the mounting member 100 in a separable joint manner, so as to facilitate the separate disassembly of the mounting group and the material shell 200. Moreover, the material shell 200 and the mounting member 100 can also be made of different materials according to the use requirements to improve the structural stability and strength of the bin structure 10. The function of the material shell 200 is to contain materials, and an opening 210 is provided at the top of the material shell 200 to facilitate the material shell 200 to contain materials. In addition, the cross-sectional area of the opening 210 of the material shell 200 is larger than the cross-sectional area of the bottom of the material shell 200, so that at least two material shells 200 can be stably stacked along the opening 210 in a state of not being connected to the mounting member 100, thereby effectively utilizing the storage space and reducing the transportation cost.
