Airflow-preventing type unmanned aerial vehicle pesticide spraying device capable of assisting in pesticide filling

Abstract

The invention relates to the related field of pesticide sprayers, and discloses an airflow-preventing type unmanned aerial vehicle pesticide spraying device capable of assisting in pesticide filling.The device comprises a main body box, and four propeller boxes circumferentially arranged by taking the main body box as the center are fixedly connected to the tail ends of the upper sides of the left, right, front and rear end surfaces of the main body box. Meanwhile, the rotating speed of a water pump can be adjusted in real time in cooperation with a speed adjusting cavity, so that when the rotating speed of a propeller is increased, the strength of pesticide sprayed by a mist nozzle is improved by increasing the rotating speed of the water pump, the influence of the airflow generated by the propeller on the mist pesticide is reduced, and normal spraying of the pesticide is guaranteed; when the speed is reduced, the spraying intensity of the pesticide is reduced accordingly, so that the normal flight of the device is prevented from being influenced by a counter-acting force generated by continuous high-intensity pesticide spraying, and when the pesticide is used up, a pesticide filling piston can be automatically started to move, so that the effect of assisting in supplementing the pesticide is realized, and the spraying efficiency of the pesticide is improved.

Description

technical field [0001] The invention relates to the related fields of pesticide sprayers, in particular to an anti-airflow type unmanned aerial vehicle pesticide spraying device that can assist to charge the pesticide. Background technique [0002] At present, drones have gradually entered the agricultural field, that is, spraying pesticides on large-scale crops through drones, but since the flight and ascent of drones are based on the lift generated by the propeller, most pesticides are sprayed in the form of mist. As a result, the downward airflow generated by the propeller will affect the spraying of sprayed pesticides with low pressure, and if the high-pressure nozzle is used continuously, it will produce a reaction force, which will affect the normal flight of the UAV. After the man-machine pesticide is used, it generally needs to be shut down and applied manually, which is cumbersome and inefficient.
