SPRAYER BOOM Russian patent published in 2023 - IPC A01M7/00 

FIELD: agriculture.

SUBSTANCE: sprayer boom (1) contains a sectional truss (2) mounted on the spraying unit of a mobile power vehicle (3) with equipment (4) for placing and supplying working fluid, a working fluid spray system, including a hydraulic manifold (5), blocks (6) spraying working fluid connected to them, hydraulic slot nozzles (7) with electromagnetic control installed in blocks (6), an air support system for sprayed drops of liquid, including a discharge air duct (8), a fan (11), air nozzles (12). The discharge air duct (8) is made in the form of a horizontally located hollow thick-walled semi-cylinder (13) with hollow walls (15) and end bases (14), formed by dissecting a circular thick-walled cylinder with hollow walls and end bases by the plane in which its axis of symmetry (a-a) lies. Air sprayers (12) are installed in the flat lower walls of the air duct (8), in the upper inner part of which a hydraulic manifold (5) with spray units (6) connected to it is installed. In each block for spraying the working fluid, slot nozzles (7) are installed, located at the vertices of a regular pentagon (19) and symmetrically along a circle (20) described by a pentagon, one of the vertex (C) of which and the bisector (bb) of the angle at this vertex lie on straight line (c-c), parallel to the axis of symmetry (a-a) of the air duct (8) in one vertical plane, and the long axis (n-n) of the nozzle of each slot nozzle (7) is parallel to the axis of symmetry of the air duct.

EFFECT: increase in the efficiency and quality of differentiated application of pesticide working fluid, minimizing the drift of pesticides beyond the treated areas of the field to maximum permissible concentrations.
