Abstract
The utility model relates to a drip irrigation having humidity auto-control function, which utilizes the principle that wood materials are in expansion when wet and shrinkage after drying to make a valve close and open, and thereby, the flow of water in the pipe can be controlled. The utility model is formed by the connection of a cylinder supporter and a cuboid aqueduct; the inner part of the supporter is provided with a wood expansion block (1); the inner part of the aqueduct is provided with a sphere valve (2) and a spring (3); a diaphragm (4) is arranged between the supporter and the aqueduct. The wood expansion block (1) expands because of trickle irrigation or falling rainwater to increase the moisture in the soil, pressing the sphere valve (2) to interrupt the water stream, and drip irrigation stops.
Description
The utility model relates to a kind of humidity drip irrigation equipment of the drip irrigation equipment, particularly trees of control automatically that utilizes.
Existing drip irrigation equipment major part is used for crops, thereby little, the concentrated characteristics of irrigated area are arranged.But for large-area plant cultivation, afforestation is particularly said for the region of no water source, arid, seasonal drought, present drip irrigation equipment expensive and can't implementing.
The purpose of this utility model provides a kind of drip irrigation appliance, and it utilizes humidity to realize control automatically, can realize the positioning and quantitative irrigation to plant effectively, prevents the loss and the evaporation of moisture content.
The purpose of this utility model is to realize like this.Utilize wood materials chance hygral expansion and dry physical phenomenon of shrinking, therefore closed the and unlatching of valve controls flowing of water in the control piper.When soil reaches certain humidity, the pipeline closure, drip irrigation stops.When antecedent soil moisture, pipeline is opened again, and drip irrigation is proceeded.
The concrete structure of utility model is provided by following drawings and Examples.
Figure one is the profile according to the utility model principle.Arrow A is water inlet, and B is water outlet.(1) is plastic casing among the figure, and many holes are arranged on the wall, in order to see through moisture content.(2) be the filter sand layer, prevent that soil particle from passing through.(3) be the plastic cylinder support, Qi Bishang has many holes, and the effect in hole is with (1) hole, and set screw (4) is arranged at its bottom, near the bottom four screws (5) is arranged.Flange bracket and plastics aqueduct (9) join, and have film (13) to be separated by therebetween, prevent that current from advancing in the support.A plastic slide block (6) is arranged, the cylinder that it is shaped as an end face is interior concave spherical surface in the rack tube.Have many above it and hole its central axes, the effect in hole is with (1) hole.What match with slide block is a wooden expanding block (7), is cylindrical in the middle of it, and there is hoop with holes (8) on the surface, and hoop is gapped with rack inner wall, and its other end is a conical butt, the adjacent barrier film of end face (13).Aqueduct (9) is a plastics cuboid.There is a rounded channels in the centre that itself and flange bracket join, and two discharge orifices are arranged at the bottom of close groove.The bottom of groove is porose, and spring (11) is arranged in the hole.There is a radius to equal the sphere valve (10) of groove radius in the groove.Notch has an annulus banking stop (12), prevents that valve from going out groove.
The embodiment of utility model is: under dry situation, connect the water source, set screw (4) is dwindled the gap of valve (10) face and groove face, makes water maintenance drip irrigation state, can be adjusted to one of several seconds as required, then screw is tightened, and adjusting finishes.Keep the device of drip irrigation state, in case run into water, its expanding block (7) expands, and makes the bottom surface of the sphere pressing groove of valve (10), the blocking-up current, and drip irrigation stops.When dry, expanding block (7) shrinks, and by the strength of spring (11), makes the sphere of valve (10) and groove face produce the space, and current pass through, and drip irrigation is proceeded.Because it is protruding sphere shape that expanding block (7) is designed to an end, and has slide block (6) spacing, mid portion and backing holding cylinder (3) inwall is gapped, and the other end is a conical butt, so the volume of its axial expansion can all be displaced to the direction of valve (10).Calculate according to 2% the coefficient of expansion, the volume after an expanding block that is about 60MM expands can satisfy making valve sphere and groove face closure, blocks current.
Use of the present utility model: with this device with newly plant during thing together places into the soil, its delivery port must adjacent plant roots, the position of its control valve and the delivery port maintenance level of trying one's best, connect a retaining bag on its water inlet A, the retaining bag is fixed on soil surface the best, can observe and additional moisture content.Can bury one or more control valves according to floristics, size and use a retaining bag.Expanding block will carry out anticorrosion and surperficial moisture absorption to be handled.Plastic tube in placing into the soil should be able to bear certain pressure.
Claims (3)
1, drip irrigation equipment, the particularly device that trees are irrigated, the aqueduct (9) that it is characterized in that cylinder stent (3) and join with it.One expanding block (7) is arranged in the support (3), it is characterized in that its shape is cylindrical in the middle of being, an end is a sphere shape, and an end is a conical butt, and its material is wooden.
2, device according to claim 1 is characterized in that expanding block (7), and its shape is cylindrical in the middle of being, an end is a sphere shape, and an end is a conical butt.
3,, it is characterized in that its material is wooden according to claim 1,2 described devices.
