[0003] In the prior art, drones are used for spraying pesticides. Pesticides are placed in spray pots and sprayed on farmland through spray devices;

[0004] However, a spraying device that is too long will affect the balance of the drone when it lands, and a spraying device that is too short will reduce the spraying efficiency and make the spraying time too long. Utility Model Content

[0005] The purpose of the utility model is to provide a drone spraying assembly to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a drone spraying assembly, comprising:

[0007] A top plate, a surface of which is fixed with support rods;

[0008] A spray pot, wherein a connecting pipe is fixed to the bottom of the spray pot, a spray pipe is fixed to the end of the connecting pipe, a telescopic pipe is arranged inside the spray pipe, and a magnet is arranged inside the spray pipe; and

[0009] The motor is arranged on the surface of the spray pipe.

[0010] Preferably, the spray pot is filled with pesticides, the interior of the connecting pipe is communicated with the interior of the spray pot, the interior of the connecting pipe is communicated with the interior of the spray pipe, and spray holes are provided at the bottom of the spray pipe and the bottom of the telescopic pipe.

[0011] Preferably, the telescopic tube is inserted into the spraying tube and can move in the spraying tube, an extension plate is fixed on the surface of the telescopic tube, and teeth are arranged on the surface of the extension plate.

[0012] Preferably, the end of the motor is connected to a gear, the gear is located inside the spray pipe, the gear can rotate inside the spray pipe, and the teeth on the surface of the gear are meshed with the teeth on the surface of the extension plate.

[0013] Preferably, a spring is arranged inside the spray pipe, one end of the spring is connected to the inner wall of the spray pipe, and the other end of the spring is connected to a magnet, and the magnet can move up and down in the spray pipe.

[0014] Preferably, an extension rod is fixed to the end of the telescopic tube, the extension rod is located inside the spraying tube, and the end of the extension rod can be adsorbed on the surface of the magnet.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The pesticide proposed in the utility model is located inside the spray pot. During spraying, the spray device squeezes the pesticide in the spray pot into the inside of the connecting pipe. The pesticide squeezes the magnet, causing the magnet to descend. The magnet no longer adsorbs the extension rod. The gear rotates under the drive of the motor. The gear rotation drives the extension plate to move, so that the telescopic tube extends to the outside of the spray pipe, lengthens the length of the spray pipe, and speeds up the spraying efficiency. The telescopic tube can be retracted into the spray pipe by the motor drive, and does not affect the landing of the drone. The magnet is adsorbed on the surface of the extension rod under the push of the spring, so as to prevent the telescopic tube from extending from the spray pipe when the motor is not working.
