In conclusion, the unmanned aerial vehicle air-drop system can realize unmanned loading, air-drop and air-drop of a plurality of air-drop containers, greatly improves the air-drop working efficiency of the unmanned aerial vehicle and reduces the cost. Meanwhile, the air-drop packing box driving device 4 in the cargo conveying system 1 is arranged on the upper portion of the cargo hold of the unmanned aerial vehicle, the air-drop packing box is pushed to move in a lower cantilever mode, loading, unloading and air movement of the air-drop packing box are achieved, and driving is stable. Set up the lift transverse guide 8 who keeps apart the air-drop packing box in the goods transmission system 1, reduce to below the packing box bottom plate when the air-drop packing box removes, rise when the air-drop packing box removes to fixed position, carry on spacingly to the air-drop packing box, effectively prevent the free movement of air-drop packing box in the warehouse. The cargo space air-drop system 2 adopts a double-bracket 10 form and a driving form, supports the air-drop cargo box on two sides below the cargo box bottom plate during air transportation, moves towards two sides during air drop to remove the support of the air-drop cargo box, and drops the air-drop cargo box out of the cargo space under the action of gravity, so that the structure is stable. The system adopts the form of throwing by the lower air-drop cabin door 14, realizes air-drop by gravity and reduces resource consumption.
The above-mentioned contents are only for illustrating the technical idea of the present invention, and the protection scope of the present invention is not limited thereby, and any modification made on the basis of the technical idea of the present invention falls within the protection scope of the claims of the present invention.
