BOOM-MOUNTED SPRAY NOZZLE ASSEMBLY WITH COMPACT DESIGN WITH SEVERAL SPRAY NOZZLES Russian patent published in 2025 - IPC B05B1/16 

FIELD: spraying.

SUBSTANCE: invention relates to spray booms for liquids, such as those towed in the field by a tractor or similar for agricultural spraying, and more specifically to an improved spray nozzle assembly for use on such spray rods. Liquid spraying system comprises an elongated liquid spray bar designed to support a plurality of spray nozzle assemblies, each of which has a compact design, which provides the possibility of transportation and storage of the spray boom with less tendency to damage. Each of the spraying nozzle assemblies comprises an inlet section for liquid and a pair of legs for supplying liquid to the spray nozzles and their supports extending from the inlet section for liquid and passing in front in the transverse direction relative to the spray bar at an acute angle to each other. On each liquid supplying leg of the housing a spray nozzle is installed, wherein appropriate shutoff valve is arranged behind spray nozzle. Inlet section for liquid, Y-shaped housing and support components of spray nozzles and shutoff valve are made with possibility of quick-release assembly and disassembly.

EFFECT: invention provides more reliable folding or rotation of the boom sections with their arrangement side by side without undesirable contact interaction of the spraying nozzle assemblies, safe installation on the spraying boom for liquid, safe installation of a spray nozzle assembly on a rod for supply and spraying of liquid and electric wiring of the corresponding electronic shutoff valves, simple design, and provides the possibility of its cost-effective manufacturing.
