Abstract

The invention discloses a tangential centrifugal agricultural sprayer nozzle with two spraying hole sheets. The tangential centrifugal agricultural sprayer nozzle comprises a liquid inflow pipe joint and a nozzle body, wherein the liquid inflow pipe joint is provided with a liquid inflow channel. The liquid inflow pipe joint is tangentially connected with the nozzle body. The liquid inflow channel is tangential to an inner cavity of the nozzle body. The two spraying hole sheets are installed in a spraying cavity of the nozzle body and divide the spraying cavity into a flow mixing chamber and an eddy chamber. The two-spraying-hole-sheet structure is adopted, a traditional spraying cavity is divided into the eddy chamber and the flow mixing chamber, high-speed pesticide liquid is buffered in the eddy chamber and then sprayed out through the flow mixing chamber, the pressure of the pesticide liquid and the speed of mist drops are reduced, the spraying diameter is increased, the drifting phenomena can be effectively reduced, and harm caused by pesticide drifting to the ecological environment and human health is reduced. The nozzle is compact in structure, reliable in work, convenient to detach and install, suitable for manual sprayers and various self-propelled pesticide spraying machines, extremely high in economical efficiency and practicality and high in application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of agricultural spraying devices, and in particular relates to a tangential centrifugal agricultural sprayer nozzle with double nozzle holes. Background technique [0002] Spray drift is one of the important causes of agricultural environmental pollution in my country. The most direct and effective way to solve spray drift is to improve the anti-drift performance of the atomization part, that is, the nozzle. The knapsack sprayer is the most widely used chemical pesticide spraying device in my country, and the tangential centrifugal nozzle is the most important working part of the knapsack sprayer, and its anti-drift ability directly affects the amount of pesticide drift. Domestic and foreign studies have shown that when the diameter of spray droplets is less than 150 μm, the spray droplets are prone to drift. At present, the structure of ordinary tangential centrifugal nozzles in my country is relatively si...
