As shown in fig. 1, in the plant protection pesticide spraying device provided in this embodiment, the powder dosing box 10 has a funnel structure inside, and the bottom outlet of the funnel structure is connected to the input end of the auger conveying device 11, which is used for proportioning solid pesticides, such as for dispensing related pesticides of octasulfide and phosphorus. Because the feeding amount of the solid pesticide conveyed by the auger conveying device 11 is in direct proportion to the opening time, the auger conveying device 11 can convey the solid pesticide raw material to the mixing box 30 through the first conveying pipe 12 roughly and accurately. A liquid material such as water or a diluent of a water-soluble material is stored in a liquid dosing tank 20 and is fed to a mixing tank 30 through a second feed pipe 21, while a flow meter 22 measures the volume of the fed liquid and a first solenoid valve 23 is switched on and off.

In the process, the inboard end of the delivery tube 635, i.e., the outlet of the delivery tube 635, is tilted slightly forward. Therefore, after the pesticides sprayed by the plurality of guide pipes 635 are converged, the sprayed pesticide flows collide with each other to form an atomization effect due to the high pesticide spraying pressure. Meanwhile, negative pressure is also formed in the inner cavity of the inner core 634 in the forward spraying process of the pesticide, so that the ambient gas enters the first air cavity B1 through the tail part of the atomizing nozzle 63, the inner annular surface of the inner core 634 close to the front end is provided with an annular inner protruding structure 6341, the inner protruding structure 6341 is used for accelerating the gas flowing through the inner part of the inner core 634, and therefore the gas velocity of the second air cavity B2 is high, and the effect of optimizing the atomizing effect is achieved.
