Cylindrical sawtoothed labyrinth double-runner irrigator

Abstract

The invention discloses a cylindrical sawtoothed labyrinth double-runner irrigator. The cylindrical sawtoothed labyrinth double-runner irrigator comprises an outer sleeve which is provided with a water inlet nozzle and two water outlet nozzles, wherein the two ends of a PE (polyethylene) dropping pipe with a plurality of holes are inserted into the two water outlet nozzles respectively to form an annular continuous water drop-outlet irrigator; a water separator is arranged in the outer sleeve of the double-runner irrigator and comprises a cylindrical water separator body; two pits are symmetrically formed in the outer surface; a plurality of water baffle banks of which the outer surfaces are on the same circumferential surface with the outer circle surface of the water separator body are arranged in parallel in each pit; the ends, which are connected with the side walls of the pits, of adjacent water baffle banks, are in the 180-degree direction to form a labyrinth runner; a plurality of decompression teeth are arranged on each water baffle bank; a clearance is formed between two opposite rows of decompression teeth; a runner inlet is formed in one end of one runner; a runner outlet is formed in the other end of the runner; two runner inlets are respectively communicated with the water inlet nozzle; and one runner outlet is communicated with one water outlet nozzle. The irrigator is not blocked, is uniform in water pressure, does not cause backflow, and is applied to irrigation for fruit trees, forest shrubs and the like, which are relatively large or irregular in planting space and relatively large in root diameter.

Description

technical field [0001] The invention belongs to the technical field of tree irrigation, and relates to an irrigator for drip irrigation of trees, in particular to a cylindrical sawtooth-shaped labyrinth double-channel irrigator for drip irrigation of trees with irregular row spacing and large root diameters. Background technique [0002] At present, most of the drip irrigation equipment used are simple single-channel water outlet drippers, although the drippers have solved the problem of clogging the drip holes with sediment and other impurities carried in the drip irrigation water. However, it still cannot meet the irrigation needs of plants with irregular row spacing and large root diameters such as various fruit trees, ecological forests, and shelter forests, especially the irrigation of plants in areas where water resources are extremely scarce such as Gobi, deserts, and hills has not been effective for a long time. solve.

Problems solved by technology

[0002] At present, most of the drip irrigation equipment used are simple single-channel water outlet drippers, although the drippers have solved the problem of clogging the drip holes with sediment and other impurities carried in the drip irrigation water

However, it still cannot meet the irrigation needs of plants with irregular row spacing and large root diameters such as various fruit trees, ecological forests, and shelter forests, especially the irrigation of plants in areas where water resources are extremely scarce such as Gobi, deserts, and hills has not been effective for a long time. solve

Existing water-saving irrigation facilities, especially simple dripper-type drip irrigation facilities, sprinkler-type micro-spray facilities and small-tube outflow drip irrigation facilities, cannot achieve efficient irrigation and fertilization of plants with large root diameters.
