LOW-PRESSURE NETWORK OF DRIP IRRIGATION Russian patent published in 2018 - IPC A01G25/02 

FIELD: devices for spraying liquids.

SUBSTANCE: invention relates to the field of agriculture and can be used for irrigation of orchards and vineyards. Low-pressure drip irrigation network includes a distribution pipeline. Irrigation pipelines are connected to the distribution pipeline through the pressure regulators with drip water outlets and a by-pass device. Irrigation pipelines are suspended with the ability to move in a horizontal plane to the wire. Wire is tensioned between the posts with a positive gradient of 0.001–0.0015. Pipeline head section is fixed to the first post. End section is equipped with a tensioning device in the form of a yoke with a lanyard. Tensioning device is connected through a spring to the additional post. Bypass device is made in the form of a branch pipe. Branch pipe is connected to the end of the irrigation pipeline by means of a flexible coupling and connected to it by a cable through the block system. System of blocks is mounted on an extreme rack. Improved reliability of work is provided by equalizing the flow of water through droppers along the entire length of irrigation pipelines. Prevent siltation of the droppers and the accumulation of water in them during the inter-irrigation period.

EFFECT: operation is simplified by automatizing the process of turning on and off the retaining devices.
