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

Embodiment 1

[0015] Example 1 figure 1 In the illustrated embodiment, a capillary drip irrigation system is composed of a water level controller (14), a balance water tank (4), a water supply pipe (9), a branch pipe (8), a water diversion capillary (7) and a capillary dripper, wherein , The water level controller (14) has a power input interface (14-1), a signal input interface (14-2) and a control output interface (14-3), the water supply pipe (9) and the water diversion branch pipe (8) have their own Branch interface, the capillary dripper consists of a dripper cover (5) and a capillary bundle (6). The dripper cover (5) is a rotating body structure, and the center of the dripper cover (5) has a bayonet (5-3) , The capillary bundle (6) is installed in the bayonet (5-3) of the dripper cover (5), there is a vent (5-4) on the top of the dripper cover (5), and the dripper cover (5) There is a hand-twisting ear flap (5-1) on the outer side of the wall of the dripper. The hand-twisting ear flap ...

Embodiment 2

[0016] Example 2 figure 2 In the illustrated embodiment, on the basis of the first embodiment, the water source of the balance water tank (4) comes from a mountain stream. There are water pipes (16) and water pipes (16) between the mountain stream and the balance water tank (4). There is a solenoid valve (17) on the ), and the control output interface (14-3) of the water level controller (14) is connected to the coil of the solenoid valve (17). The other structure is the same as that of the first embodiment and will not be repeated.

[0017] The above embodiment uses the capillary principle to achieve the purpose of drip irrigation, and the water supply pipe does not need to have pressure. When in use, the water supply of the water supply pipe (9) is provided by the balance water tank (4), and the water level of the balance water tank (4) is controlled by the water level controller (14) to realize intelligent water replenishment. When the water level in the balance water tank (4...

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 in which water and nutrients needed by crops are dropped evenly and slowly into the soil of the root zone of crops through a low-pressure pipeline system and an irrigator installed on the capillary according to the water requirements of crops. The main characteristics of drip irrigation are the small amount of irrigation water, the long duration of one irrigation, and the short irrigation cycle. It can do small water and frequent irrigation, can more accurately control the irrigation volume, can reduce ineffective evaporation between trees, and will not cause water Waste, the water utilization rate can reach 95%, drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation. At the same time, it can be combined with fertilization to more than double ...
