DRIP IRRIGATION SYSTEM Russian patent published in 2019 - IPC A01G25/02 

FIELD: agriculture.

SUBSTANCE: invention relates to the agriculture. Proposed system comprises main pressure line, pump station and irrigation network. System is additionally equipped with hydromotor and additional pressure main line. Main and additional pressure unidirectional lines are connected to each other by pipelines with droppers coming from them. Pipelines are made with gradual reduction of diameter of clearance in direction from pressure main to droppers, and total number of pipelines is determined by formula , where n is number of pipelines; A is pipeline wall area, m²; A₀ - area of walls of half of pipelines, m²; d is pipeline diameter, mm; d₀ - diameter of half of pipelines, mm; ρ is pipeline wall density, g/cm³; ρ₀ - wall density for half of pipelines, g/cm³; E is Young's module of pipeline wall, Pa; E₀ Young's modulus of wall for half of pipelines, Pa; h is pipeline wall thickness, mm; h₀ is wall thickness for half of pipelines, mm.

EFFECT: enabling application of fertilizers into irrigation device and improvement of their mixing with liquid, as well as energy conservation throughout the system.
