off, unmanned aerial vehicle main part 1 leaves ground, the first spring 305 pushes the sliding rod 304 to move downwards, thereby pushing the supporting rod 301 to rotate, the rotating pipe 204 is pulled to rotate towards the ground, thereby the height of the nozzle 205 is lower than that of the main body 1 of the unmanned aerial vehicle, thereby the nozzle 205 sprays medicine below the main body 1 of the unmanned aerial vehicle, the amount of the medicine sprayed on the main body 1 of the unmanned aerial vehicle is reduced, when a worker contacts the main body 1 of the unmanned aerial vehicle, the safety is higher, the main body 1 of the unmanned aerial vehicle can suck the medicine in the water tank 201 into the water pump 202 by driving the water pump 202 to work and then spray the medicine out of the nozzle 205 through the conduit 203 and the rotating pipe 204, so that crops can be sprayed with the medicine, after the medicine is sprayed, the main body 1 of the unmanned aerial vehicle returns to land, the roller 302 contacts with the ground, the supporting rod 301 is pressed to rotate towards the outside under the action of gravity of the main body 1 of the unmanned aerial vehicle, thereby the sliding rod 304 is pushed to move upwards, the first spring 305 is compressed, thereby pushing the rotating pipe 204 to rotate, making the rotating pipe 204 rotate upwards, making the spray head 205 far away from the ground, avoiding the damage caused by the contact friction of the spray head 205 and the ground, pressing the pushing block 401 to separate the limiting block 407 and the limiting groove 410, and then pulling out the water tank 201, after the trigger rod 601 is separated from the rubber plug 605, the rubber plug 605 is reset under the push of the seventh spring 604, thereby blocking the suction pipe 602 from communicating with the outside, the water tank 201 is separated from the pressing rod 504, under the pulling of the sixth spring 505, the pressing rod 504 moves upwards to reset, the rotating rod 510 is driven to retract into the unmanned aerial vehicle main body 1, under the action of the first torsion spring 702, the driving guard plate 701 is rotationally reset, the second torsion spring 704 rotationally resets the driving baffle 703, therefore, the rotating shaft 511 and the rotating rod 510 are protected, and the sand carried by the bottom end of the water tank 201 when contacting the ground is prevented from contacting the rotating shaft 511, the rotating rod 510 and the sliding rod 503 to damage the device.
