Abstract
The utility model relates to a suck-back and back-flow drip irrigator for drip irrigating trees, which comprises a water-sucking bottom semi sphere and a water-sucking top semi sphere, in them sponge fillers are provided. The water-sucking bottom semi sphere is made up by a base of the drip irrigator connected with a bottom semi sphere casing, the water-sucking top semi sphere is made up by a supporting seat connected with a top semi sphere casing. A plurality of water-sucking holes are provided in the base of the drip irrigator and the supporting seat. The center of the water-sucking top semi sphere is provided with an intermediate pipe, at outer of which an outer pipe is looped; the center of the supporting seat is provided with an inner pipe, which is inserted into the intermediate pipe. A spring is provided between the bottom semi sphere casing and the supporting seat of the top semi sphere, and a protection net is provided between the base of the drip irrigator and the supporting seat. At outer side of the base of the drip irrigator, a protective housing is provided. Both the water-sucking bottom semi sphere and the water-sucking top semi sphere are located in the protective housing. On the protective housing, a water-permeating window is provided. As rainwater seeps into soil after filtering by the drip irrigator, no foreign matter in rainwater will block the drip irrigating channels, so the drip irrigation can work long time.
Description
Technical field
The utility model relates to a kind of irrigation rig that is used for trees are carried out drip irrigation, particularly a kind of suck-back reverse-flow type drip irrigation emitter.
Background technology
In urban afforestation, the periphery of tree all crosses a tree pond, in the tree pond, be provided with a plurality of aqua storage tanks, the tank base plate is provided with several soakaway trenchs that inserts depths, the face of land, the rainwater that stores in the tree pond can be permeated to depths, the face of land step by step by soakaway trench, reach the effect of carrying out drip irrigation to trees.Because rainwater is that filtered is just directly infiltrated soil by soakaway trench,, also just lost function of drop irrigation very soon so the foreign material in the rainwater are easy to just soakaway trench be blocked.
Summary of the invention
The purpose of this utility model is a kind of suck-back reverse-flow type drip irrigation emitter that prevents that soakaway trench from being blocked by foreign material of design, it can be uniformly that water is dripped the people discontinuously is underground, the growing environment that protects trees prevents the desertification of soil simultaneously, makes full use of natural rainwater resource.
The purpose of this utility model realizes as follows: suck-back reverse-flow type drip irrigation emitter described in the utility model comprises suction end hemisphere and suction top hemisphere; Suction end hemisphere is formed by connecting by drip irrigation emitter base and end hemisphere shell, be provided with the sponge filler in the suction end hemisphere, the drip irrigation emitter base is provided with a plurality of suctions hole, the central authorities of suction end hemisphere from top to bottom are provided with in one pipe and extend outside the drip irrigation emitter base, be arranged with an outer tube in the outside of middle pipe, the sidewall of this outer tube is provided with a plurality of permeable holes; Suction top hemisphere is formed by connecting by supporting seat and top hemisphere shell, is provided with the sponge filler in the hemisphere of suction top, and supporting seat is provided with a plurality of suctions hole, the central authorities of supporting seat be provided with one outward extending in pipe, pipe is inserted in the middle pipe on the suction end hemisphere in this; Be provided with spring between end hemisphere shell and top hemisphere supporting seat, this spring handle suction end hemisphere and suction top hemisphere are connected in one; Between drip irrigation emitter base and supporting seat, be provided with protection network; The outside at the drip irrigation emitter base is provided with containment envelope, and suction end hemisphere and suction top hemisphere all are located in the containment envelope, are provided with permeable window on containment envelope.
The central authorities of described top hemisphere shell are provided with the water level sign.
The central authorities of described containment envelope offer a circular hole.
Permeable window on the described containment envelope is a shutter.
The inboard of the permeable window on the described containment envelope is provided with screen pack.
Described spring is a volute spring.
Described spring is made of plastic.
Good effect of the present utility model is as follows: owing to rainwater is to filter the back through this drip irrigation emitter to infiltrate soil, so with regard to having avoided the foreign material in the rainwater to block the drip irrigation passage, make function of drop irrigation permanently effective; In addition, the utility model can prevent that in the growing environment that protects trees soil from desertifying, and protects natural rainwater resource can not run off, and good effect is played in urban afforestation.
