The working steps of the embodiment are as follows:

firstly, the unmanned aerial vehicle body 1 is suspended and stopped after flying to a proper position, the telescopic end of an electric push rod 503 is contracted, an electromagnetic clutch 405 is electrified to enable an upper layer rotating shaft 406 and a lower layer rotating shaft 401 to be in transmission connection, a sliding plate 505, a spring guide rod 508 and a rack 507 are driven by a connecting plate 506 to move, the rack 507 drives a second gear 502, a first gear 410, the upper layer rotating shaft 406 and the lower layer rotating shaft 401 to rotate, the upper layer rotating shaft 406 and the lower layer rotating shaft 401 rotate approximately 120 degrees clockwise, a torsion spring 402 deforms and accumulates force, during the period, the lower layer rotating shaft 401 drives a control plate 6 and a lower layer shifting plate 404 to rotate, the control plate 6 opens a falling port 24, therefore, two passing material bags 409 cannot fall from the falling port 24, the upper layer rotating shaft 406 drives the upper layer shifting plate 408 to shift the material bags 409, so that the material bags 409 in the area in front of the falling port 24 area moves to the falling port 24 and falls from the falling port 24, a connecting rod, at the moment, the inner wall of the telescopic sleeve 3 is approximately smooth so that the material bag 409 can smoothly pass through;

step two, the electromagnetic clutch 405 is powered off, the lower rotating shaft 401 rotates under the action of the elastic restoring force of the torsion spring 402, the lower poking plate 404 pokes the material package 409 falling into the lower throwing cavity 23 from the falling opening 24 to the throwing channel 232, and the material package 409 is projected out after passing through the arc-shaped channel 231, the throwing channel 232 and the telescopic sleeve 3 and reaches a pre-calculated throwing point; the material control plate 6 closes the drop opening 24 again.

Step three, the electromagnet 509 is electrified to adsorb the rack 507, so that the rack 507 is not contacted with the second gear 502 any more, the electric push rod 503 drives the rack 507 to reset, then the electromagnet 509 is powered off, and under the action of the spring guide rod 508, the rack 507 resets and is meshed with the second gear 502 again;

step four, repeating the steps 1-3, thus delivering the goods and materials packages 409 stored in the three areas in sequence.
