Description

Irrigation hose

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a watering hose for supplying water to crops, and more particularly, to a watering hose which prevents the cut water hole from being torn and expanded by water pressure.

In addition, the present invention is easy to manufacture and can be supplied at low cost, the amount of water discharged can be kept constant, when the vinyl is covered on the water irrigation can be supplied to the water continuously because the vinyl does not block the watering hole It's about hoses.

Water supply is essential to plant cultivation.

Means for supplying water to these plants include thick walled thick pipes and hoses made of thin synthetic resin.

Among the means for supplying water to the plant (hereinafter referred to as "watering"), the irrigation hose is made of thin synthetic resin as described above, and simply forms a plurality of holes in the wall of the hose. Thus, the water inside the hose is configured to be sprayed to the outside, so that a predetermined structure is installed in this hole, so that the water is not sprayed and soaks into the soil.

FIG. 12 illustrates another example of a watering hose which simply forms a watering hole 110 in a wall of the hose 100.

As shown, in the case of a conventional irrigation hose, a circular or "-" shaped irrigation hole 110 is formed, and the irrigation hose has advantages and disadvantages according to the shape of the irrigation hole 110.

In the case of a watering hose having a circular watering hole, when water first starts to flow, water is first discharged through the watering hole formed at the beginning of the water inflow, and water is supplied to the end of the hose even when water is supplied to the end of the hose. The amount of water discharged alone is greater than the amount of water discharged into the watering hole at the end, there was a problem that can not be evenly watered.

On the other hand, in the case of the irrigation hose formed with the "-" type of watering hole, this "-" type of watering hole is a state in which the hose is cut out with a knife without cutting the hose, so the water must be filled inside the hose to open the water and the water is discharged to the outside. do. Therefore, even if water flows into the hose, the watering hole remains blocked, and the incoming water is filled from the end of the hose to the water inflow portion. The hole is opened and water inside the hose is supplied to the outside.

Therefore, in the case of an irrigation hose having a "-" type irrigation hole, water is discharged evenly from each irrigation hole formed in the hose to supply water evenly to the plant, but the "-" type irrigation hole formed by cutting with a knife has a hose Due to the water pressure inside, the water can be torn in the longitudinal direction of the watering hole. As the watering hole becomes larger, the watering hose itself cannot be used for a long time.

Although not shown, another irrigation hose may be configured in such a manner that, as mentioned above, water is discharged into the irrigation hole without being sprayed far by installing a fine structure in the part where the irrigation hole is formed.

However, in order to install the microstructure in the irrigation hose having a small diameter as described above, the hose manufacturing process is complicated, and there is a problem in that the price of the hose increases because many equipments are to be provided.

The present invention was developed to solve the above problems of the prior art, and an object of the present invention is to provide an irrigation hose which is prevented from being torn and expanded by the water pressure to the irrigation hole cut in the "-" type.

In addition, the present invention is easy to manufacture and can be supplied at low cost, the amount of water discharged can be kept constant, when the vinyl is covered on the water irrigation can be supplied to the water continuously because the vinyl does not block the watering hole The purpose is to provide a hose.

The watering hose according to the present invention for achieving the above object is made of a thin synthetic resin and the hose is formed in the wall of the watering hole, the watering hole is formed by cutting long in the longitudinal direction of the hose, both sides of the watering hole In order to prevent tearing and lengthening by the water pressure, a part of the opposite surfaces of the hose is pressed against each other to further form a crimping portion to form a flow path from the inside of the hose to the watering hole.

The present invention has the effect of preventing the "-"-type irrigation hole is torn and expanded by the water pressure by pressing both sides of the irrigation hole.

In addition, since only the portion of the hose formed with the watering hole is pressed to prevent the watering hole from being torn, it is easy to manufacture and can be supplied at low cost, and the watering hole is formed by forming a winding maze shape that leads to the watering hole. The amount of water discharged through it can be kept constant, and since the watering hole is formed on the side of the hose, when the vinyl is covered thereon, the vinyl does not block the watering hole so that water can be continuously supplied.

Hereinafter, a watering hose according to the present invention will be described in more detail with reference to the accompanying drawings.

1 is a plan view showing a part of the irrigation hose according to the present invention, Figure 2 is a perspective view showing a part of the irrigation hose of Figure 1 in a folded state, Figure 3 is a part of the irrigation hose of Figure 1 folded The side view shown in FIG.

As shown, the watering hose according to the present invention is formed by cutting the watering hole 1 in the longitudinal direction of the hose 10, the watering hole (1) is torn on both sides of the watering hole (1) by hydraulic pressure In order to prevent the elongation, the opposing faces of the hose are pressed together, and the pressing parts 21 and 22 are further formed to form the flow passage 21a from the inside of the hose to the watering hole 1.

As shown in FIGS. 1 and 2, the watering hole 1 is formed at an edge when the hose 10 is rolled up, and the watering hole 1 of the pressed hose 10 is formed. Both sides are pressed to form the crimping parts 21 and 22.

If the crimping portions 21 and 22 are formed too deeply to the inside of the hose, it may interfere with the flow of water passing through the inside of the hose. Therefore, the depth of the crimping portions 21 and 22 is preferably about 2 mm to 5 mm.

In addition, the watering hole 1 may be formed on both sides of the hose 10, so that the water supply range can be widened.

Of course, even when the watering hole 1 is formed on both sides of the hose 10, the pressing portions (21, 22) are formed on both sides of the watering hole (1).

The irrigation hose configured as described above forms the crimping portions 21 and 22 on both sides of the irrigation hole 1 so that a flow passage 21a is formed between the two crimping portions 21 and 22.

The part forming the flow path 21a has a form in which the synthetic resin constituting the hose is stacked up and down, and when the parts forming the flow path 21a are in close contact with each other, the flow path 21a may be blocked. As shown in Fig. 8D-, projections 23 are formed on the surfaces facing each other so that portions of the flow path 21a do not come into close contact with each other.

In the drawings, the shape of the protrusion 23 is shown as a spherical shape, but it may be formed to be long in the longitudinal direction of the hexahedron shape or the flow path as an example.

In the method of forming the protrusions 23 in the flow path 21a, when the hose 10 is manufactured, as shown in FIG. 6, protrusions are formed on the entire inner wall of the hose 10, and the crimping parts 21 and 22 are formed. It can be constructed by applying a force when squeezing, which causes the protrusions to distort, causing the hoses to stick together.

The pressing parts 21 and 22 may be formed in various ways, but preferably, both sides of the watering hole 1 of the hose in which the watering hole 1 is formed are thermally fused. It can be said to be the most easily formed method.

The watering hose configured as described above discharges water through the watering hole 1 to the outside, but the water discharged to the watering hole 1 is sprayed to a far distance.

When water is sprayed at high pressure, it is not only a problem that leaves are caused by water pressure in the case of fragile body. As shown in FIG. 10, when the irrigation hose is installed on the toad, the vinyl covered by the tofu may be separated and separated by the tofu by the pressure of the discharged water. When the vinyl is pushed by the water pressure, the vinyl covers the plant. This growth may be lost.

Accordingly, when the irrigation hose is installed inside the vinyl covered with the ridge as shown in FIG. 10, it is preferable that the water discharged from the irrigation hole 1 flows down the outer wall of the hose without being sprayed at high pressure.

In order for the water to be discharged to the watering hole (1) to flow to the hose or the duct to lower the pressure of the water discharged to the watering hole (1), and thus to reduce the pressure of the water discharged to the watering hole (1) It is preferable to form 21a) narrow and long.

In order to form the narrow passage 21a in this manner, as shown in FIGS. 5 to 9d, the passage 21a is formed.

That is, one of the pressing parts 21 and 22 formed on both sides of the watering hole 1 is formed to be long in the longitudinal direction of the hose, and the flow path 21a is twisted in the compression part 21. It is formed.

By winding the flow passage 21a in this way, the flow of water passing through the flow passage 21a is delayed, so that the water discharged to the watering hole 1 is not sprayed at a high pressure, but the outer wall of the outer hose of the fruit hole 1 It will seep into the soil.

The irrigation hose configured as described above is installed on the ridge as shown in FIG. 10, but the irrigation hole 1 is installed to face the side rather than upward or downward, and even if the plastic is covered on the irrigation hose thus installed ( 1) is not blocked by vinyl.

In addition, as shown in the figure, the pressing portions 21 and 22 are formed only at both sides of the portion where the watering hole 1 is formed, so that when the water is filled in the hose 10, the periphery of the portion where the watering hole 1 is formed is recessed. It becomes a fine state and the watering hole 1 is not blocked by vinyl.

In addition, the irrigation hose of the present invention forms a circle as a whole except for the part where the irrigation hole 1 and the crimping parts 21 and 22 are formed when deployed, thereby providing a connector having a cylindrical connection as shown in FIG. When connecting to the irrigation hose can be easily connected.

That is, in the conventional watering hose, the watering hole is formed on both sides of the hose, and the watering hole is formed long along the portion where the watering hole is formed. Since it is difficult to connect to the connector because it is formed as a crimping portion is formed only around the portion of the irrigation hole is formed as described above and the other part is maintained in a circular shape so that the connector can be easily connected will be.

In the irrigation hose configured as described above, the shape of winding the flow path 21a may be variously configured as shown in FIGS. 9A to 9D, and other various modifications may be made. The shape does not limit the scope of the claims.
