Description

TECHNICAL FIELD

[0001] The utility model belongs to the drip irrigation waterer design field, especially relate to a flow channel detachable patch type drip irrigation waterer. BACKGROUND

[0002] Waterer is the most critical component of micro-irrigation system, its structure, hydraulic performance and quality are directly related to the irrigation uniformity and operation reliability of the whole system. At present, with the increasingly serious problem of water resources shortage, high-sand water, reclaimed water, micro-saline water, etc. are usually used as irrigation water sources. These irrigation water sources contain a large amount of suspended solids, organic matter, microorganisms and other impurities. These substances will increase the risk of waterer clogging and reduce the service life of the waterer.

[0003] Drip irrigation is a kind of local irrigation that uses plastic pipes to deliver water to the roots of crops through the orifices or drippers on the PE pipes with a diameter of about 10mm. It is the most effective water-saving irrigation method in arid and water-deficient areas, and the utilization rate of water can reach 95%. It is the most effective water-saving irrigation method in the world, and is also an indispensable irrigation measure for developing modern and energy-saving agriculture.

[0004] In actual drip irrigation projects, the irrigation water source is mainly surface water such as rivers, lakes and ponds. These water sources often contain a lot of silt. Even if the drip irrigation system is equipped with perfect filtering equipment, some fine particles of silt will still enter the flow channel of the waterer. And the flow channel of the waterer is usually designed to be about 1mm. This causes the fine particles of silt entering the flow channel to be unable to pass smoothly and to be deposited and accumulated in the flow channel. The clogging of the dripper will reduce the irrigation uniformity, cause the growth of crops to be inconsistent and reduce the yield, and the replacement of the pipe will increase the investment and labor. At present, the clogging problem is a major factor restricting the popularization and application of drip irrigation technology.

[0005] Waterer is the core component of micro-irrigation system, its structure, hydraulic performance and quality are directly related to the irrigation uniformity and operation reliability of the whole system. Under the background of the current water resources shortage, unconventional water sources such as high-sand water, reclaimed water and micro-saline water are increasingly used as irrigation water sources. However, the impurities such as suspended solids, organic matter and microorganisms contained in these water sources greatly increase the risk of waterer clogging and shorten its service life.
