Determination of the outlet diameter of the spray tip of the universal sprayer

Abstract

To eliminate the shortcomings of serial fan sprayers, the JV “Agrikhim” developed a universal sprayer that treats crops based on controlled airborne flows introduced simultaneously within ± 90 0 from the sprayer’s symmetry axis (a total of 180 0) around the entire perimeter of the treatment area the entire width of the machine. The obtained dependences and the nomogram built on their basis allow setting the required rate of application of the working solution at a given speed and diameter of the spray tip of the sprayer by adjusting the pressure when the working solution enters the spray tip.

Technical means for collecting seeds of desert-pasture fodder plants

“…The disadvantages of the mower are the heavy weight of the metal separator, the complexity of manufacturing the blades of its drums, which are carried out according to the involute, as well as large losses of seeds due to the small clearance between the blades of the drum, due to which the seed heap, not having time to pass through the gaps between them, leaves the surface of the separator. in together with hay in loss [11][12].…”
