Abstract

The utility model provides an underground drip irrigation watering device, which is composed of a casing connected with a water delivery hair pipe, an inner core composing a main body of a flow passage and a pressure compensation block which can adjust the size of the flow passage or close the flow passage along with the change of system pressure. The utility model has the advantages of uniform irrigation, compact structure, peculiar design and convenient installation, and the blockage caused by the negative pressure of a system is avoided, and certain flow quantity is kept.

Description

The underground drip irrigation irrigator
The utility model relates to a kind of field irrigation device, especially relates to a kind of irrigation device that can be used for underground drip irrigation.
At present, the irrigation method of traditional broad irrigation is also continued to use in China rural area, causes the significant wastage of water resource.Along with the reach of science, irrigation technique is also being constantly brought forth new ideas, and a kind of irrigation method that is applicable to economic crops---underground drip irrigation is on probation abroad.Underground drip irrigation is that the water delivery hollow billet is imbedded below the face of land, and a plurality of irrigators are installed on the water delivery hollow billet, gives crop irrigation by these irrigators.But because water-carriage system produces negative pressure, it is undecided always to cause irrigator to stop up this problem, so this new technology of underground drip irrigation also fails to promote the use of at home.
The purpose of this utility model is to fill the domestic gaps, provide a kind of underground drip irrigation irrigator, this device can be avoided effectively because of producing the obstruction that negative pressure causes in the system, when causing that when the system pressure variation or because of the landform variation water inlet pressure changes, can keep the flow of irrigator that big variation does not take place, guarantee to pour water evenly.
The utility model provides following technical scheme to achieve the above object:
A kind of underground drip irrigation irrigator, it comprises: shell, inner core and pressure compensation piece; Be provided with the runner through hole in the middle of the described shell, be provided with a circle flange at the end of runner through hole, the bottom of shell is the cylinder of hollow; Described pressure compensation piece is arranged between shell and the inner core, described flange below; Described inner core profile is the boss shape, is provided with runner in the middle of the boss top, and is provided with inside and outside two circle sidewalls, forms hopper in the middle of the two side, and the lateral wall top is provided with a water inlet, and the madial wall top is provided with a delivery port that communicates with runner; Described inner core bossing is embedded into housings, and tight fit or bonding is adopted in the junction.Described shell is connected with the water delivery hollow billet, and inner core constitutes this irrigator runner main body, and the pressure compensation piece is made of elastomeric material, can change with pressure to regulate the runner size or close runner.
In the such scheme, described pressure compensation piece thickness is 0.5-1.5mm.
In the such scheme, the runner in the middle of the described inner core be I type hole or The type hole.
In the such scheme, the water inlet on the described inner core lateral wall is arranged on a side, and the delivery port on the madial wall is arranged on opposite side.
Underground drip irrigation irrigator of the present utility model has the following advantages:
1, avoid negative pressure to stop up; When this device portal place pressure less than zero the time, the pressure compensation piece is pressed on the flange of shell flow field end tightly, can close runner fully, prevents that any material from sucking runner because of intrasystem negative pressure, thereby avoids negative pressure to stop up.
2, pour water evenly; When system pressure changes or changes when causing the pressure variation of this device water inlet because of landform, the contact area of the shape of pressure compensation piece and pressure compensation piece and runner changes thereupon in this device, thereby keep the flow of this device that big variation does not take place, guarantee to pour water evenly.
3, design is unique; The shell of connection water delivery hollow billet and the core arrangement design of flow main body are gone up original and different, ingenious arrangement, and compact conformation, easy for installation.
Below in conjunction with drawings and Examples, further specify the utility model.
Fig. 1 is the installation diagram of underground drip irrigation irrigator;
Fig. 2 is the front view of inner core in this device;
Fig. 3 is the vertical view of inner core in this device;
Fig. 4 is the front view of the another kind of structure of inner core in this device;
Fig. 5 be among Fig. 2 A to view.
Fig. 1 illustrates the structure of underground drip irrigation irrigator of the present utility model, and with reference to Fig. 1, this device is made up of shell 1, inner core 3 and pressure compensation piece 2 three parts; Shell 1 is connected with the water delivery hollow billet, and inner core 3 constitutes the runner main body of this device, and pressure compensation piece 2 adopts special elastomeric material to make, and can change with system pressure to regulate the runner size or close runner.Be provided with runner through hole 12 in the middle of the shell 1, be provided with a circle flange 11 in the lower end of runner through hole 12, the bottom of shell 1 is the cylinder of hollow; Pressure compensation piece 2 is arranged between shell 1 and the inner core 3, flange 11 below; With reference to Fig. 2, the profile of inner core 3 is the boss shape, is provided with runner 35 in the middle of the boss top, and is provided with inside and outside two circle sidewalls, forms hopper 34 in the middle of the two side, and the lateral wall top is provided with water inlet 32, and the madial wall top is provided with delivery port 31; The bossing of inner core 3 is embedded in the shell 1, and tight fit or bonding is adopted in the junction.
The thickness of pressure compensation piece 2 is 0.5-1.5mm.When system pressure just often, it presses close to the runner 35 of inner core 3; When system pressure changes or because of landform changes when causing that irrigator water inlet pressure changes, the shape of pressure compensation piece 2 changes, change the contact area of pressure compensation piece 2 and runner, make changes in flow rate little, guarantee to pour water evenly.
When this device water inlet pressure less than zero the time, pressure compensation piece 2 is close on the flange 11 of shell 1, can close runner fully, prevents that any material from sucking runner because of negative pressure, thereby avoids stopping up.
Runner in the middle of the inner core 3 can be the I type, as shown in Figure 4, also can be Type is straight hole 35 on the boss, and boss is horizontal tap hole 33 down, as shown in Figure 2.
With reference to Fig. 2, the water inlet 32 on inner core 3 lateral walls is arranged on the left side, and the delivery port 31 on the madial wall is arranged on the right side.The opening shape of water inlet 32 can be made up big and down small groove shape as shown in Figure 5.
For ease of installing, the top of shell 1 makes circular platform type 13, just is stuck behind the insertion water delivery hollow billet.
Shell 1 and inner core 3 can be used the engineering plastics injection mo(u)lding, can be with materials such as ABS or PE.
