DROPPING DEVICE Russian patent published in 2003 - IPC

FIELD: agriculture, in particular, drop irrigation systems. SUBSTANCE: dropping device has casing with inlet and outlet branch pipes, cover and locking member mounted inside casing. Water flow divider is positioned in casing for free rotation and is adapted for defining pressure and drain cavities inside casing. Divider is made in the form of three-armed lever, with two arms extending diametrically and third arm at right angle with respect to said arms. Outer arm is oriented toward inlet branch pipe. Said arm has rib formed on its peripheral part and defined by faces inclined at different angles to radial plane. Locking member is shaped similar to rigidity rib. Its upper edge is positioned at the level lower than water flow divider. Upper edge of locking member forms water discharge channels arranged in casing lower part and hydraulically communicated with expansion chambers, whose bottom parts are provided with calibrated equally spaced drop-forming openings. EFFECT: increased efficiency, provision for faultless operation of dropping device and uniform dispensing of calibrated drops. 5 cl, 2 dwg
