FARM CROP IRRIGATION APPARATUS Russian patent published in 2004 - IPC

FIELD: agricultural engineering. SUBSTANCE: apparatus has power unit equipped with accumulator having flexible irrigation pipeline provided with water outlets and winding mechanism. Accumulator is equipped with gasket having slit-shaped discharge opening of width equal to width of flexible irrigation pipeline folded in the form of strip. Pipeline has diameter variable proportionally to variations in piezometric pressure through the length of pipeline and in the form of sleeve, which may be turned inside out. Accumulator has additional water outlets provided with petal valves, which may be fixed on outer and inner surfaces of pipeline with different distance therebetween. Water outlets with smaller distance between them are designed for common furrow irrigation and water outlets with larger distance between them are designed for irrigation with rare furrows-slots. EFFECT: increased efficiency in irrigation and wider operational capabilities. 7 dwg
