DRIP IRRIGATION SYSTEM FOR FRUIT AND BERRY AND FOREST NURSERIES Russian patent published in 2013 - IPC A01G25/00 

FIELD: agriculture.

SUBSTANCE: drip irrigation system for fruit and berry and forest nurseries comprises a hydraulically connected water source (1), a pumping station (6), a filter, a pressure gauge (15), a shut-off valve, the main pipeline, a network of distribution (17) and irrigation pipelines (18), and droppers. The water source (1) of the pumping station (6) is provided with a diversion chamber-collector (5) equipped with a trash screen (3) and a fish protection structure (4). Pumps of the pumping station (6) are connected to a water-driven tower-collector (7) hydraulically connected to the module of water electroactivation, including a DC generator (8) or rectifier in all-mains operation and flowing electric activator (10), behind which through the connecting pipes the fertiliser injector (12) is mounted, and the distribution network (17) is connected by the irrigation pipelines (18), equipped with injectors-metering units-droppers (19). The flowing water electric activator (10) comprises a supply pipe (21) made of dielectric material which is resistant to galvanic corrosion, in the threaded part of the supply pipe (21) the slip ring (26) is mounted with the output for connection of the electric potential. The slip ring (26) is isolated from the outer electrode (22) of the electric activator (10) with the dielectric spacer (27), the outer cylindrical electrode (22) is formed of a stainless steel resistant to galvanic corrosion. Inside the outer electrode (22) the inner electrode (23) is mounted with the ability of mounting and dismounting, consisting of a central rod (31) with lobes fixed to it. The inner electrode (23) is separated from the outer electrode (22) by semipermeable shell (24) of microporous plastic, on the front side of the inner electrode (23) a guide device (25) is arranged having the blades of a left-hand direction, the inlet and outlet part of the central rod (31) are made conical, all parts of the inner electrode (23) are made of stainless steel resistant to galvanic corrosion. Supply of the electric potential to the outer electrode (22) is made through the terminal (29) disposed on the electrode housing, and to the inner (23) through the contact washer (26) having an input terminal (28). The injector-metering unit-dropper (19) mounted in the pan of trees, comprises mounting tip, inside of which a shim is fixed, designed for a given flow rate, the inner cavity of the injector-metering unit-dropper (19) has a water outlet openings on the horizontals of soaking, the outer edges of the water outlet openings are closed by dished deflectors.

EFFECT: improving the quality of planting material of fruit and forest plants.
