DEVICE FOR TESTING SPRAYERS Russian patent published in 2018 - IPC A01M7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and can be used for testing sprayers of agricultural atomizers. Device for testing the nebulizers comprises a housing, a classifier table, a computer, a processing and signaling unit, a rod with a working fluid distribution unit, means for vertical movement and rotation of the rod, a supply and measurement unit for air speed, a block for supplying, regulating and controlling the flow of working fluid, a unit for measuring and evaluating the process of dispersing the working fluid, a light source. Bar is rotatable about the vertical axis by an angle of 0≤α≤360° and changes in the length of the side. Lateral side is connected on one side with the upper fixed base, and on the other hand with the lower moving base. Lower base is connected by a pivot-fixed support with a fixed rib with rotation of the lower base in a vertical plane from the horizontal position to the angle 0≤β≤20°. Air supply and distribution unit is provided with a pivoting device with an angle of rotation in the horizontal plane by an angle of 0≤γ≤180° and deflector. Deflector is made in the form of a rectangular diffuser. Larger side of the diffuser is equal to or greater than the length of the lower base of the rod. Classification surfaces for determining the unevenness and thickness of the coating are performed on opposite sides of the classifier table in parallel to each other. Surfaces are made with the ability to move them from the upper level to the lower and vice versa.

EFFECT: automation of the process of sprayers testing is ensured, accuracy and reliability of determination of the quality indexes of the distribution of working fluid are increased taking into account the influence of external influences.
