MOBILE BOOM-TYPE SPRINKLER UNIT Russian patent published in 2003 - IPC

FIELD: agricultural engineering. SUBSTANCE: sprinkler unit has low-pressure double nozzles with sectioned deflectors. Sprinkler nozzles are arranged in the following pattern: 28 double nozzles first from center toward ends of girdle have diameter of 8.5 mm, subsequent 16 nozzles have diameter of 9.3 mm, following 8 nozzles have diameter of 10 mm, two end nozzles have diameter of 15.6 mm. Sprinkler unit of such type may be used for creating new models and for reconstructing of existing sprinkler units.
