SECTIONED SPRINKLER NOZZLE Russian patent published in 1998 - IPC

FIELD: agricultural engineering. SUBSTANCE: sectioned sprinkler nozzle has body 1 with water discharge opening 2 formed as truncated cone continued by cylindrical opening with length-diameter ratio of 1.0-3.0. Flat platform 3 below water discharge opening 2 joined with deflector having width-length ratio of 0.4-1.2 forms laminar flow. Deflector is formed as double-moldboard springy board-shaped curved surface with ridge 4 ascending at an angle $$$= 20-30 deg relative to horizontal plane. Two side descending surfaces 5 are smoothly joining along curves with ascending side surfaces 8, and at ridge end are joining with plane 9 ascending at an angle $$$=40-60 deg relative to horizontal plane. While flowing through deflector, water flow is imparted acceleration and is fractured into small drops when it encounters air flow. EFFECT: increased spray beam length combined with reduced intensity, simplified construction and enhanced reliability in operation. 3 dwg
