[0004] 1. The change of the flow rate during the spraying process is realized by the change of the spraying pressure, and the atomizer of the nozzle will have the best atomization effect under a certain pressure, so the change of the spraying pressure will cause The atomizer cannot be in the best working condition, resulting in poor atomization effect, which in turn affects the actual use effect of pesticides

The present invention discloses a quantity-varying spraying system applicable to an unmanned aerial vehicle. The quantity-varying spraying system comprises a spraying execution device and a control system; the spraying execution device includes a pesticide box body, flow rate sensors, pesticide liquid pumps, a nozzle concentration controller and nozzles; the pesticide box body comprises a plurality of independent grid pesticide boxes; the lower part of each grid pesticide box is connected with the flow rate sensor, the pesticide liquid pump and the nozzle concentration controller sequentially through a pesticide liquid pipeline; each pipeline is connected in series with a one-way valve and a one-way valve control switch; the control system comprises a ground surface remote control device arranged on the ground and an on-board control device arranged on the unmanned aerial vehicle; and the on-board control device comprises a wireless transmission module, a storage module and a power module. A quantity-varying spraying in the quantity-varying spraying system can realize quantity-varying spraying in advance when working under a condition that the flow rate of the nozzles is constant. The quantity-varying spraying system has the advantages of accurate spraying range accurate and good spraying effect.
Description
technical field [0001] The invention relates to the research field of unmanned aerial vehicle plant protection equipment, in particular to a variable spraying system suitable for unmanned aerial vehicles. Background technique [0002] At present, my country is the country with the highest total application of chemical fertilizers and pesticides in the world, accounting for about 30% of the world's total consumption. At the same time, the problem of agricultural non-point source pollution caused by excessive use of chemical fertilizers and pesticides is becoming increasingly serious. Problems such as resources, environment and ecology are prominent, which have adversely affected the sustainable development of agriculture. In order to improve this problem from the root, countries around the world have a broad consensus on the development potential and application prospects of low-volume, high-efficiency, and precise pesticide application technologies, and have developed machine...
