FIELD: agricultural engineering, in particular, devices for irrigation of agricultural crops by drop irrigation method.
SUBSTANCE: dropper has casing with inlet and outlet openings. Casing is shaped as convex-convex lens. Annular channel is provided on peripheral part of casing. Casing is mounted by means of annular channel within pipeline opening. Casing is made from elastic material and consists of upper and lower parts. Inlet and outlet openings are connected through elastic membrane with channel and chamber. Additional channel provided in lower part of casing is hydraulically communicated with outlet opening and chamber. Channels provided in upper and lower parts of casing are made in the form of spirals. Spirals are imparted the shape of right-handed and left-handed involutes of circle.
EFFECT: improved quality of drop irrigation, wider range of water pressure difference within pipeline cavity.
