Description
Technical field
The utility model relates to trickle irrigation field, in particular to a kind of drip-irrigation system.
Background technique
Trickle irrigation is the moisture and nutrient that are needed water and crop by pipe-line system and trickle irrigation mouth according to crop water requirement
Uniformly and slowly instill in the soil of crop root zone.It is a kind of most effective water-saving irrigation side of current drought and water-scarce area
Formula, the utilization rate of water is up to 95%.Trickle irrigation relatively sprinkling irrigation has higher water-saving and yield-increasing effect, while can improve fertilizer in conjunction with fertilising
One times of effect or more.It is applicable to fruit tree, vegetables, industrial crops and greenhouse to irrigate, also can be used in the place of drought and water shortage
In field crop irrigation.Since trickle irrigation mouth is smaller, the water containing nutrient is easy to make to drip when fouling at trickle irrigation mouth its shortcoming
Fill mouth blocking.Since the water flow itself at trickle irrigation mouth is smaller, while trickle irrigation mouth is dripped to the root region soil of plant, when trickle irrigation mouth
When blocking, people is difficult to discover, to affect the growth of crop.
Notification number discloses one kind on May 11st, 2016 for the Chinese utility model patent of CN205213603U and is not easy to block up
Plug and unimpeded efficiently green house of vegetables drip irrigation system.Including reservoir, reservoir is communicated with drip irrigation pipe, drip irrigation pipe by aqueduct
On trickle irrigation mouth is distributed with, distributing installation has pressure sensor in drip irrigation pipe, and pressure sensor is connected with central processing unit, centre
Reason device is connected with display.When normal use, the hydraulic pressure in drip irrigation pipe tends towards stability substantially, when trickle irrigation mouth in somewhere is stifled in drip irrigation pipe
When plug, the hydraulic pressure near the trickle irrigation mouth of blocking can be bigger, and pressure sensor senses the variation of hydraulic pressure and to will test result defeated
Central processing unit is given, over the display and is alarmed；Staff according to issue alarm pressure sensor position to correspondence
Region carry out troubleshooting, do not have to entire greenhouse check, saved the investigation time, saved labour.
But when trickle irrigation mouth is plugged, if staff temporarily checks without discovery or without the time, it can seriously affect
The effect of trickle irrigation, to influence the normal growth of plant.Therefore when trickle irrigation mouth is blocked, then staff is needed to arrange immediately
Look into, thus the drip irrigation system there is a problem of it is inconvenient to use.
Utility model content
The purpose of this utility model is to provide a kind of drip-irrigation system, have the advantages that convenient to use.
The above-mentioned technical purpose of the utility model has the technical scheme that

The circulation status of water in spare pipe 15, makes staff that can easily find the drip irrigation pipe 13 to break down, plays convenient to use
Effect.
Water inlet pipe 23 is equipped with water valve 41 of intaking into water water valve 41 and is equipped with the water inlet knob 42 for controlling its logical closed state, standby
It is identical as the direction rotated when the direction and opening of water inlet knob 42 with knob 32.Water inlet knob 42 is fixedly connected with into water gear
43, spare rack gear 35 is fixedly connected with the water inlet rack gear 44 engaged with water inlet gear 43, spare rack gear 35 and water inlet rack gear 44
Towards on the contrary.Spare rack gear 35 moves up and water inlet rack gear 44 is driven to move up, the water inlet driving water inlet gear 43 of rack gear 44
With water inlet knob 42 rotate, make to rotate into water knob 42 with spare knob 32 it is contrary, and make into water water valve 41 closing.It is real
Water inlet water valve 41 is closed while now opening spare water valve 31, plays effect convenient to use.Prevent water inlet pipe 23 from will make excessively
Water concentrate on the position of the trickle irrigation mouth 14 not being plugged, play the role of improving irrigation effect and facilitate irrigated crop.
Outlet pipe 21 is equipped with the water outlet water valve 22 for controlling its on-off.By water outlet water valve 22 control outlet pipe 21 in and into
The flow velocity for entering the water in water inlet pipe 23 plays the effect for adjusting speed of dropping water, plays effect convenient to use.Water valve 22 will be discharged
It closes, reduces the water in drip irrigation pipe 13 and trickle irrigation mouth 14, the effect of trickle irrigation mouth 14 convenient to overhaul can be played.
23 side wall of water inlet pipe is provided with observation slot 24 along its length, and water inlet pipe 23, which is equipped with, will observe what slot 24 was blocked
Transparent panel 25.Observe the height of water level in water inlet pipe 23 by transparent panel 25, when in water inlet pipe 23 dilutional hyponatremia or it is very few when,
It is discharged water valve 22 by adjusting, adjustment flows into the flow velocity of the water in water inlet pipe 23, can play the effect for facilitating dropper.
Specific embodiment: when trickle irrigation mouth 14 is plugged, liquid discharge rate declines in water inlet pipe 23 and drip irrigation pipe 13
23 liquid level of water inlet pipe is caused to rise, the hydraulic pressure in water inlet pipe 23 increases.Water in water inlet pipe 23 and pressure pipe 51 pushes piston 52
It is mobile with bar 54 is abutted, and be pushed into abutting bar 54 bayonet lock 37 in pin hole 36.Spare spring drives spare rack gear 35 to moving up
It is dynamic, equipment gear 33 and spare knob 32 are rotated, spare water valve 31 is opened, allows the water to flow by spare pipe 15 and water dropping openings 16
It moves onto the soil of crop root zone, maintains the water supply to crop.Staff is facilitated to check in trickle irrigation mouth 14 and drip irrigation pipe 13
Failure, moreover it is possible to guarantee that crop being capable of normal growth.Meanwhile the intake driving of rack gear 44 water inlet gear 43 and water inlet knob 42 rotate,
Make to rotate into water knob 42 with spare knob 32 it is contrary, and make into water water valve 41 close.It realizes and opens spare water valve 31
While close water inlet water valve 41, play effect convenient to use.Prevent water inlet pipe 23 will make excessive water concentrate on not by
The position for the trickle irrigation mouth 14 blocked plays the role of improving irrigation effect and facilitates irrigated crop.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
