IRRIGATION DEVICE Russian patent published in 2012 - IPC A01G25/02 

FIELD: agriculture.

SUBSTANCE: device comprises carcass elements of the housing, a heat insulating shell, a tank, pressure piping, a level control, a water supply pipeline for irrigation, water-distribution pipelines, isolation valves and daily timer. The tank is hydraulically connected to the pressure piping, the level control and the water supply pipeline for irrigation. The device is made in the form of a space dismountable carcass structure made of pipes. In the upper part of the dismountable carcass structure a longitudinal collector is placed. The length of the collector is equal to the length of the planting bed. The collector is hydraulically connected to the side distribution pipelines. The lateral distribution pipelines are made in the form of equal symmetric relative to the longitudinal collector parallel semicircles. The plane of the parallel semicircles is perpendicular to the longitudinal collector axis. The semicircles diameter is chosen to be equal to the width of the bed B. The ends of distribution carcass pipelines are tightly plugged with vertical removable racks. The length of the vertical removable racks is chosen from the relation L=H-B/2+C, where H is total height of the carcass structure of the device after installation in the bed, C is the value of penetration of the vertical removable rack in the bed. Each distribution pipeline has the holes for irrigation from the concave side. The outer shell of the device is made removable. The collector is hydraulically connected to the tank through the normally closed solenoid valve of the water supply main pipeline for irrigation. The pressure piping of the tank comprises a normally closed solenoid valve. The tank is mounted at a height greater than or equal to H. The level control is made in the form of an electric float sensor.

EFFECT: structure enables to increase efficiency of use of the device.
