agriculture. SUBSTANCE: invention relates to mechanized watering and it can used in irrigation by discrete supply of water to moistening sites. Proposed device has accumulating reservoir with siphon communicating by its drain part through collector with watering pipelines, supply pipe with cock and siphon charging mechanism consisting of tube-liquid level pickup in accumulating reservoir, tube-breather, ejector and collector. End of liquid level pickup tube passing through hole in accumulating reservoir and end of breather tube are fitted in seats of collector cover. Ejector is made in form of tube with hole in wall. Lower end of this tube is connected through seat in collector housing with one of watering pipelines, and its upper end is located in space of siphon drain part. Hole in wall of ejector tube is located in collector space lower than end of drain part of siphon. EFFECT: simplified design, improved reliability of watering device. 3 cl, 4 dwg |
