Description

Micro-irrigation device

Affiliated technical field

The utility model relates to a kind of micro-irrigation device that green plants is carried out water-saving irrigation, and the utility model especially plays an important role to environmental protection.

Technical background

Water-saving irrigation is water-saving important means, but water saving device known today is difficult to solve hydraulic pressure to even slight irrigation problem.

Summary of the invention

In order to address the above problem, the utility model provides a kind of micro-irrigation device, and this micro-irrigation device can carry out effective water-saving irrigation to green plants, makes limited water resource can irrigate as much as possible green plants.

The technical scheme that its technical problem that solves the utility model adopts is:

The design micro-irrigation device is as the water-saving irrigation technique means.Micro-irrigation device is made up of connection joint, automatic valve, slight irrigation cylinder, outer shell, and conduit is responsible for the water input is communicated with joint.The conduit that is communicated with the joint bottom links to each other with the micro-irrigation device automatic valve, is responsible for water is imported the slight irrigation cylinder.The slight irrigation cylinder can be designed to two types: a kind of is the slight irrigation cylinder to be made ooze cylinder, make in the cylinder water by necessarily slowly speed slowly in the cylinder to outside ooze out, thereby make micro-irrigation device reach the purpose of slight irrigation; Another kind is that adherent " n " shape conduit is set on casing wall, and ribbon is set in the conduit, make water in the cylinder under the effect of ribbon siphon principle by necessarily slowly speed in cylinder, flow to outside the cylinder, thereby realize the slight irrigation purpose of micro-irrigation device.Keep certain distance and its underpart to be provided with many pores between outer shell and the slight irrigation cylinder, like this, the water that the slight irrigation cylinder is discharged not only can flow among the soil smoothly, and can realize and the isolation of soil, makes it remain clean good working order.

Of the present utility model have beneficial effect the present invention really to be:

1, can implement effective water-saving irrigation, save and the protection water resource.

2, can solve the irrigation problem of domestic plant, beautify the environment.

Embodiment

In Fig. 1, Figure 1A, Figure 1B, Fig. 1 C, Fig. 1 D, Fig. 1 E, conduit (2) sealing shroud is being communicated with on the joint (1), the end conduit that is communicated with on the joint (1) is led on the valved tube of automatic valve, automatic valve (3) places in the slight irrigation cylinder (4), slight irrigation cylinder (4) places in the outer shell (5), and tight loop (8) is installed fastening with outer shell (5) automatic valve (3), micro-irrigation device (4).Its concrete method of operation be current from conduit (2) flow into be communicated with the joint (1) and flow to be communicated with joint each in communicating pipe, flow in the automatic valve (3) by the conduit that is communicated with the joint bottom simultaneously and and then flow in the slight irrigation cylinder (4).Water body in the slight irrigation cylinder (4) is done in order to the even velocity trace and is entered lentamente among the outer shell (5) through the little row of slight irrigation cylinder.Because the inwall top and the bottom of outer shell (5) are provided with annular projection, its bottom is provided with some pores, so just can make and remain certain distance between slight irrigation cylinder and the outer shell, and the water that the slight irrigation cylinder is discharged waltzs through among the pore infiltration soil of outer shell bottom, and the slight irrigation cylinder remains the state of isolating with soil and can remain clean cleaning, thereby unlikelyly influences its work operation.

At Fig. 2, conduit is installed pincers and is made up of expansion bracket (7) and handle (6).Conduit is installed pincers and is used to install conduit.

In Fig. 3, Fig. 3 A, Fig. 3 B, Fig. 3 C, screw (9) is installed in the valved tube (11) of automatic valve on the plectane (10), taper cork (12) is positioned on the bolt head of four leaf bolts (13), the top of link arm (15) is inserted behind the square hole of four leaf bolts (13) bottoms four leaf bolts is placed among the valved tube (11), and bearing pin (14) is fixed on the valved tube.Screw (17) is installed in float on the connecting rod of link arm (15).Its concrete operation is: when anhydrous in the slight irrigation cylinder or water level depression arrive certain position, float (16) descend and utilize gravity pass through screw (17) with link arm (15) toward drop-down, driving four leaf bolts (13) and cork thereof simultaneously moves downwards, like this, automatic valve is opened, the water that is communicated with in the joint (1) flows into the slight irrigation cylinder, and the cylinder middle water level goes up.Along with the rise of slight irrigation cylinder (4) middle water level, float (16) promotes also upwards operation of link arm (15) because of upwards operation of buoyancy, drive four leaf bolts and cork thereof upwards operation the most at last valve bar up.Because the water inlet of valved tube (11) is very little, the water inlet section that is communicated with joint is very big, according to hydraulicdriven principle, valve can be shut for the less power of taper cork, because link arm (15) is to promote the operation of four leaf bolts with lever principle, so even the less buoyancy of float also can produce bigger active force on four leaf bolts, like this, the buoyancy up and down of float just can guarantee automatic valve continuously long-time operate as normal between less hydraulic pressure and big hydraulic pressure reliably.

In Fig. 4, slight irrigation cylinder (4) has two kinds of slight irrigation modes, and a kind of is inner casing (18) to be made ooze cylinder, and the water body that makes the slight irrigation cylinder oozes out from inside to outside with the mass rate of emission of setting under the effect of cylinder middle water level pressure, thereby realizes the slight irrigation purpose of slight irrigation cylinder; Another kind is that " n " shape fibre conduit (19) is set on the casing wall of inner casing (18), the adherent setting of " n " shape fibre conduit (19), half inwall that reclines, half outer wall that reclines, " n " shape pipe does not discharge the water in the cylinder, but by the siphonage of fiber water is outwards discharged water body by the ribbon (20) of loose placing " n " shape pipe, thereby realize the slight irrigation purpose of slight irrigation cylinder, according to the actual needs, a plurality of " n " shape pipe can be set on the slight irrigation casing wall or change the thin thick of ribbon, thereby reach the slight irrigation purpose of different water yields.

In Fig. 5, Fig. 5 A, Fig. 5 B, to hang bolt nut (25) shut off valve (22) is locked in the valved tube (21), the push rod (24) on the shut off valve (22) freely passes through to hang the jogger hole (26) on the bolt nut (25).When the past decline of the water in the slight irrigation cylinder, shut off valve (22) descends and finally is stopped at extension bolt nut (25) and locates, and while water is from valved tube inflow cylinder; When the past rising of water in the cylinder, float (23) come-up also promotes push rod (24) and makes the also water inlet of final plant closure valved tube (21) of shut off valve (22) rising.
