Description

A kind of water-saving irrigation system

Technical field

The utility model relates to a kind of water-saving irrigation system, particularly relates to adopting slight irrigation, drip irrigation technique, have water-saving, energy-conservation, irrigate evenly, increase output, improve quality, adaptable a kind of water-saving irrigation system.

Background technology

Micro irrigation technology comprises drip irrigation, microspray irrigation, bubbling irrigation and sub-irrigation at present, cardinal principle is the need water requirement according to plant, by pipe-line system and the irrigator that is installed on the final stage pipeline, moisture required in the plant growing and nutrient are directly delivered near the plant root the soil surface or soil layer exactly, but all there is following shortcoming in existing irrigation technique: at first, the moisture irrigation volume generally calculates according to the time, can not carry out analysis and judgement according to surface humidity, moisture is irrigated in decision then, waste water resource can not satisfy the plant growing primary demand; Next, when the irrigation plant was applied fertilizer, the general employing directly added the water source with liquid medicine, with irrigating fertilizer was delivered to plant root then, and the easy like this fertilizer that causes dilutes, and fertilizer runs off easily.

Summary of the invention

The utility model is at the deficiency of existing irrigation technique, provide a kind of have water-saving, energy-conservation, irrigate evenly, increase output and improve quality, adaptable a kind of water-saving irrigation system.

Realize the above object, the technical solution adopted in the utility model is:

A kind of water-saving irrigation system is irritated by water source, water pump, feed pipe, cistern, control room, non-return valve, the master switch of pouring water, fertilizer apparatus, manometer, main filter, water meter, arm, slave computer, soil humidity sensor, mini sprinkler, water dropper, hollow billet, drip irrigation arm, afterbody switch, flushing valve, main, fertilising switch, fertilizer applicator, fertile adjustable valve, fertilising and is formed; Wherein water pump is positioned in the water source, be used for irrigation water is drawn into feed pipe, cistern can provide standby water by feed pipe, feed pipe communicates with main, non-return valve is installed on the main, the master switch of pouring water, fertilizer apparatus, manometer, main filter and water meter, arm is installed on the main front end, flushing valve is installed on main filter bottom, arm divides two groups up and down, on its middle and upper part arm mini sprinkler is installed, and with liftoff surface the certain altitude distance is arranged, be convenient to large tracts of land and carry out micro spray irrigation, the bottom arm is positioned on the ground surface, and the afterbody switch is installed, the drip irrigation arm is distributed with hollow billet on the drip irrigation arm, water dropper is installed on the hollow billet, be convenient to plant root is directly carried out dripping irrigation, soil humidity sensor links to each other with slave computer, and is positioned on the face of land.

Described fertilizer apparatus is irritated by fertilising switch, fertilizer applicator, fertile adjustable valve, fertilising and is formed, and the switch that wherein applies fertilizer, fertilizer applicator are installed with on main, and fertile adjustable valve is installed on the fertilizer applicator, and fertilizer applicator is irritated with fertilising and communicated.

Described control room carries out wireless telecommunications with slave computer, afterbody switch and is connected, and after slave computer is measured soil humidity information by soil humidity sensor, signal is uploaded to the control room, and the control room carries out switch control by analysis and judgement to the afterbody switch electromagnetic valve.

The utility model adopts micro spray irrigation and drip irrigation technique to irrigate simultaneously the plant face of land and plant root, reaches to irrigate even, energy-conservation, water saving effect; Fertilizer apparatus is installed in employing on main can reach the combination of irrigating with fertilising to simultaneously plant being applied fertilizer in irrigation, is more conducive to plant absorbing; Adopt the installation soil humidity sensor to test, avoid heavy irrigation, economize on resources, by the control room soil humidity information is carried out analysis and judgement simultaneously, and then directly control afterbody switch on the arm, automaticity height irrigating moisture.

Fig. 1 is the structure chart of utility model;

Embodiment

As shown in Figure 1, a kind of water-saving irrigation system is made up of water source 1, water pump 2, feed pipe 3, cistern 4, control room 5, non-return valve 6, the master switch 7 of pouring water, fertilizer apparatus 8, manometer 9, main filter 10, water meter 11, arm 12, slave computer 13, soil humidity sensor 14, mini sprinkler 15, water dropper 16, hollow billet 17, drip irrigation arm 18, afterbody switch 19, flushing valve 20, main 21, fertilising switch 81, fertilizer applicator 82, fertile adjustable valve 83, fertilising filling 84; During concrete enforcement, if can utilize water pump 2 directly from water source 1, to extract irrigation water in feed pipe 3 when the dried up seedbed of irrigated land is nearer, if dried up seedbed is far away, can utilize cistern 4 water to adopt for feed pipe 3, feed pipe 3 communicates with main 21, irrigation water passes through non-return valve 6 from main 21, the master switch 7 of pouring water, manometer 9, main filter 10 and water meter 11 flow to arm 12, and then carry out micro spray irrigation by 15 pairs of chamaephytes of mini sprinkler, 16 pairs of plant roots of water dropper directly carry out dripping irrigation on the hollow billet 17 by being installed on simultaneously, wherein non-return valve 6 is used to stop the reverse refluence of water, manometer 9 is used to survey water flow pressure on the main 21, water meter 11 is used to add up water consumption, impurity filters in 10 pairs of main 21 water of main filter, in order to avoid stop up mini sprinkler 15 and water dropper 16, residual impurity can be opened and washes by being installed on main filter 10 bottom flush valve 20.

If need can to close the master switch 8 of pouring water to irrigating plant apply fertilizer the time, open fertilising switch 81, fertilizer applicator 82, by fertilising irritate 84 with the fertilizer pump to main 21, fertile adjustable valve 83 is used to regulate the fertile amount size of pump.

Wherein soil humidity sensor 14 links to each other with slave computer 13, and be positioned on the face of land, soil humidity sensor 14 is uploaded to control room 5 by slave computer 13 with signal after measuring soil humidity information, control room 5 carries out switch control by analysis and judgement to magnetic valve afterbody switch 19, and then water dropper 16 carries out flow-control on the hollow billet 17 to being installed on.
