Capillary drip irrigation system

Abstract

The invention discloses a capillary drip irrigation system and relates to a drip irrigation device. The capillary drip irrigation system comprises a level controller, a balanced reservoir, a water supply pipe, a branched water diversion pipe, a water diversion capillary and a capillary drip head; each of the water supply pipe and the branched water diversion pipe is provided with a branched connector, and the capillary drip head is composed of a drip head cover and a capillary bundle; the drip head cover is mounted at the upper end of the water diversion capillary, the lower end of the water diversion capillary is connected to the branched connector of the branched water diversion pipe, the lower end of the capillary bundle extends into the branched water diversion pipe through the pipe space in the water diversion capillary, and the upper end of the capillary bundle is led out from the drip head cover; the inlet end of the branched water diversion pipe is connected to the branched connector of the water supply pipe, and the inlet end of the water supply pipe is connected to a supplied-water output connector of the balanced reservoir; an upper-limit water level electrode, a lower-limit water level electrode and a feed electrode which are arranged in the balanced reservoir are connected to corresponding input ports of the level controller through leads. By the arrangement, water level can be intelligently controlled, drip irrigation can be realized by the aid of the capillary principle, and the drip head cannot be plugged.

Description

technical field [0001] The invention relates to drip irrigation technology, in particular to a drip irrigation device. Background technique [0002] Drip irrigation technology is an irrigation method that drips water and nutrients required by crops into the soil in the root zone of crops evenly and slowly through a low-pressure pipeline system and an irrigator installed on a capillary tube according to the water requirements of crops. The main feature of drip irrigation is that the amount of irrigation water is small, the duration of one irrigation is longer, and the cycle of irrigation is short. Waste, the water utilization rate can reach 95%. Compared with sprinkler irrigation, drip irrigation has a higher effect of saving water and increasing production. At the same time, it can be combined with fertilization to more than double the fertilizer efficiency. It is suitable for irrigation of fruit trees, vegetables, commercial crops and greenhouses, and can also be used for ...

Problems solved by technology

[0003] However, the disadvantages of the current drip irrigation technology are: drip irrigation uses water with a certain pressure, and the drip irrigation system must be equipped with water pumps, filters, control and measurement equipment (pressure gauges, control valves, flow regulators, etc.), water transmission and distribution pipelines at all levels And drippers, therefore, the drip irrigation system is expensive, once called "expensive technology", only used in high value-added economic crops; because impurities will make the drippers easy to block, so the water source should be strictly filtered, high operating costs
