MOVABLE IRRIGATION APPARATUS Russian patent published in 2006 - IPC A01G25/09 

FIELD: agricultural irrigation systems.

SUBSTANCE: irrigation apparatus has immovable support and pipeline sections supported by self-propelled supports for synchronous movement and connected with each other. Pipeline sections are provided with sprinkler units mounted by means of T-shaped inserts between pipeline sections. Sprinkler units have increasing flow rates and irrigation radii with increasing discrete values from immovable support toward terminal sprinkler unit. Each of sprinkler units is joined to free end of T-shaped insert through set of diaphragms. Diaphragms are adapted for continuous altering of water flow effective section. Diaphragms have identical construction. Each of diaphragms is provided with opening offset to its peripheral edge.

EFFECT: enhanced reliability in operation, reduced irrigation erosion of soil owing to uniform distribution of precipitations and increased efficiency of movable irrigation apparatus.
