Abstract

The utility model discloses a siphon drip irrigation bag, which comprises a water storing bag and a siphon. The utility model has the advantages that one end of the siphon is connected with a float and is arranged in the water storing bag, the other end of the siphon is arranged outside of the water storing bag, and the end part is arranged at the lower position of the bottom surface of the water storing bag. The siphon drip irrigation bag provided by the utility model has the advantages that the structure is simple, the cost is less by using the bag, i.e. a plurality of ten yuan per mu, laying engineering is not required, and the irrigation is easy to implement. Drip irrigation is realized by the simple device which has the advantages of money saving and easy manufacture, and compared with the existing drip irrigator, the utility model can save more water.

Description

The siphoning and drip bag

The utility model relates to a kind of drip irrigation appliance, especially a kind of Drip irrigation bag that is applicable to arid areas such as mountain region, desert.

At present, known drip irrigation appliance is to lay pipeline, connects the water source, and the micropore that utilizes drip head is directly toward ground drip irrigation.One of shortcoming of this drip irrigation appliance is one-time investment big (investing about 2000 yuan for every mu), and is heavier for China's peasant burden: secondly,, connect the water source owing to can't lay pipeline to forest in the desert on the Yushan Hill or fruit tree, thereby can not drip irrigation.Its three, on ground, volatilization loss is big with water droplet.

The purpose of this utility model provides a kind of Drip irrigation bag, and it is not only cheap, need not to lay pipeline, and is easy to implement, and directly water splashed in the soil, thereby water saving more.

For achieving the above object, the utility model is taked following design:

The Drip irrigation bag that the utility model provides includes water storage bag and siphon pipe, be connected with a float at a described siphonal end, a described siphonal end that is provided with float places described water storage bag, its other end is located at outside the described water storage bag, and its end places the position lower than the bottom surface of described water storage bag.

When in use, can make a jar shape water storage bag with plastic film, the water bag that goes out like this is easy to storage and transportation, water is injected bag, at this moment, a described siphonal end that places the water storage bag is because the effect of float floats over water, by the design to the material of float, volume siphonal this end floated on apart from the water surface one segment distance as 1 centimeters, can prevent that with this silt (sediment), floating thing etc. from stopping up the siphon pipe port.The water storage bag of this Drip irrigation bag is placed the plant next door of wanting drip irrigation, establish drip irrigation hole digging of plant such as root, the described siphonal other end is placed this hole, preferably with soil the hole is buried again, described end is positioned at below the height of described water storage bag bottom surface, like this, water in the water storage bag will continuously, drop by drop inject plant roots, realize drip irrigation, and do not need to lay pipeline, evaporation of water also can significantly reduce.

For entering described siphon pipe with water, the foreign material in the anti-sealing cause its obstruction, can on the end in it is located at the water storage bag, gluing be covered with screen cover, enter with current with presumable silt, floating thing, suspension and bubble in the further anti-sealing and cause siphonal obstruction in the described siphon pipe.

Also have this siphoning and drip of problem bag to solve, regulate its speed of dripping exactly, the utility model has designed two kinds of solutions: the first changes the degree of depth of siphonal delivery port, and it is dark more that delivery port buries, and flow velocity is big more; It two is that to change described siphonal inner hole section long-pending, and concrete grammar has two, the one, and the siphon pipe of configuration different thicknesses: the 2nd, be provided with the device that changes the siphon pipe caliber, reduce flow velocity, by said apparatus siphon pipe is shriveled some and get final product.

The siphoning and drip bag constructions that the utility model provides is simple, uses it, only needs cost expense (every mu of tens of approximately units in ground) seldom, in addition, does not also need laying project, and is easy to implement.Just realized drip irrigation by the simple mechanism that not only saves money but also be easy to do like this, and more economized on water than existing drip irrigation appliance.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 8 is the vertical view of second embodiment of float.

As shown in Figure 1, Drip irrigation bag includes water storage bag 1 and siphon pipe 4, end at siphon pipe 4 is connected with a tubular float 2, on the barrel of tubular float 2, establish perforation apart from its upper end 1 centimeters, shown in Fig. 2,3 and 4, siphonal termination plugs wherein fixing with forming a type, an end that is provided with float 2 of siphon pipe 4 places water storage bag 1, gluing is covered with screen cover 6 on the water inlet that goes out water bag 1 of this end, its other end is located at outside the water storage bag 1, and its end places the position lower than the bottom surface of water storage bag 1 to imbed soil.

In use, water storage bag 1 water inlet 3 has from it been filled with water (volume for example is 10 liters), and it is lain on the other soil of the sapling of waiting to water, and stands firm in order to make water storage bag 1, should dig a pit on the ground, allows the water storage bag is flat to crouch wherein.Because float 2 and screen cover 6 mechanical connections are at the water inlet place of siphon pipe 4, float floats about 1 centimeters in the underwater with the siphon pipe water inlet, can prevent that like this siphon pipe from being blocked by silt, floating thing.Siphon pipe 4 becomes back the type structure can realize regulate the purpose of the flow velocity that drips by the radius of curvature ρ that regulates back the type section at the float place, when the radius of curvature ρ that returns the type section hour, siphonal inner hole section is long-pending to diminish, a speed is reduced, as shown in Figure 6, otherwise, drip speed and increase as shown in Figure 5.

The structure of float can be taked different structures because of water quality is different.Fig. 2, Fig. 3, float shown in Figure 4 are tubular construction, nozzle is provided with up and down, it is applicable to the more situation of silt in the water, and silt can not be deposited on the float of tubular construction morely, makes it sink to water storage bag bottom gradually and increase bag bed mud sand to stop up siphonal chance.Fig. 7, float shown in Figure 8 are slab structure, and it is applicable to the less situation of silt in the water to establish the hole on the thickness direction of float plate, and the float of this structure is made more convenient, at the bottom of in the few water of silt, not sunk to bag by pressure may.
