Description

Drip hose

The present invention relates to a drip hose for supplying a small amount of water required for cultivation of crops, and more particularly, the structure for decompression in the drip hose has a minimal simple structure in the form of a bar as well as a drip hose It relates to a drip hose that allows proper inflow of water according to the internal pressure and the discharge location of water formed in the drip hose according to the location of crops by the perforation of the dedicated blade jig.

In general, drip hoses are used to properly supply water when growing crops. They are arranged side by side at regular intervals on the land, and each drain hole is formed at regular intervals to supply water to the location where crops are planted.

The water supply from the drip hose is discharged through the discharge hole by the pressure of the pump. A drip (drip) for supplying under reduced pressure is provided.

In the above, as the drip drip, a piece-type drip drip that is fused to the bottom of the discharge hole and a strip-type drip drip with a relatively long length are used.

Herein, the application of the strip drip is described as an example.

Each drip part is formed in the strip body that is fused to the inner surface of the drip hose so that the drip strip is located between the discharge hole and the discharge hole formed at a predetermined interval in the drip hose.

In the above, water flows into the drip part between a plurality of protrusions or grooves, and the introduced water is decompressed through a decompression path formed between protrusions that are alternately formed one by one in a zigzag form, and then discharged formed in the drip hose at the end of the decompression. Water is discharged through the discharge space located on the ball.

Here, each discharge hole formed at regular intervals in the drip hose is formed in the drip hose using a protruding bar formed on the discharge space of the drip strip, that is, the protruding bar is pushed upward and then pushed up by the protruding bar. By cutting the drip hose, each discharge hole is formed.

As a result, the operation for forming the discharge hole in the drip hose is quite cumbersome and inconvenient.

In the prior art in which a strip drip shape is applied to a drip hose as described above, as disclosed in Korean Patent Registration No. 10-0754779 (hereinafter referred to as 'Patent Document 1'), the outer shell, including the outer shell, has two layers. The overlapping sheets arranged by heat bonding as described above, the main passage formed between the outer layer and the innermost overlapping sheet among the overlapping sheets, the decompression passage formed between the overlapping sheet and the overlapping sheet, the main passage portion A technology such as a pressure control drip tape including a plurality of drain holes formed at the boundary of the pressure reducing passage and the pressure reducing passage has been published.

In addition, as disclosed in Korean Patent No. 10-1805445 (hereinafter referred to as 'Patent Document 2'), an inlet, a decompression unit, and an outlet are formed to have a layered structure in the longitudinal direction of the drip hose, and the inlet and the decompression part and the outlet part have been posted technology like a drip hose which is formed to be connected to a plurality of moving passages.

However, in the prior art document 1, by forming a main passage portion and a pressure-reducing passage portion between the parts where two or more overlapping sheets are heat-bonded to the outer skin, the bonding operation of heat-bonding two or more overlapping sheets is quite cumbersome and difficult.

In addition, there is also a disadvantage in that the heat bonding portion is spaced apart or separated when an abnormal internal pressure is generated due to the supply of water according to the heat bonding.

In addition, when a small error occurs in a portion to be heat-bonded due to a small error during heat bonding, there is a disadvantage in that the decompression efficiency decreases as well as the discharge of water.

Prior Art Document 2 discloses that a decompression unit formed for decompression is a decompression passage portion, a first side portion, a first partition piece, a second guide projection, a first guide hole, a second side portion, a second partition piece, a second guide projection, and a second As well as having a fairly complex structure including the guide hole, the outlet also has a disadvantage in that it is quite cumbersome and inconvenient to manufacture due to the complicated structure including the discharge induction part, the discharge part, the support part, and the discharge hole.

In particular, since the pressure-reducing unit has a shape such as “Ω” or “∧” or “∩” or “Π” that is continuously arranged in the longitudinal direction of the drip hose, it is more cumbersome and inconvenient to manufacture.

In addition, in Prior Art Documents 1 and 2, the discharge hole through which water is discharged is formed at a designated location by the discharge hole formed in the heating joint or the discharge part, so that when the discharge hole is not located at the position where the crops are planted, the water supply is properly performed It also has the disadvantage of not being defeated.

Republic of Korea Patent Publication No. 10-0754779 Republic of Korea Patent Publication No. 10-1805445

The specific technical solution of the present invention for solving the various conventional problems as described above is that the structure for decompression in the drip hose has a minimal and simple structure in the form of a bar, as well as the flow of water according to the pressure in the drip hose. The purpose of this is to provide a drip hose that allows the discharge of water formed in the drip hose according to the location of the crop to be made by the perforation of the dedicated blade jig as well as the proper inflow.

Another specific technical solution of the present invention is to prevent deformation due to attachment of the inner surface of the drip hose.

Another specific technical solution of the present invention is to select the amount of water discharged according to crops so that the perforation can be made.

The specific technical solution of the present invention for solving the above specific technical problem is that unit drips having a water inlet area, water pressure reduction area and water discharge area are continuously repeated to supply a small amount of water required for growing crops. In the drip hose having a strip-shaped drip strip formed so as to be attached to the inner circumferential surface, the strip drip is an elastic material capable of shape deformation and shape restoration by the water pressure of water flowing along the inside of the drip hose, and is located on the upper surface of the base member. A water inflow path, a water pressure reducing path and a water discharging path are included between the first and fourth protruding bars protruding in the form of a bar of a predetermined height so as to be able to be attached to the inner circumferential surface of the drip hose, wherein the water inflow The furnace is formed between the first protruding bar and the second protruding bar, and spaced a predetermined distance from the base member between the first and second protruding bars so that the water is spread wide or narrow depending on the difference in water pressure in the drip hose, respectively. and forming an inlet slit of the water pressure reducing path so as to be connected to the water inflow path by a plurality of first passages formed at a predetermined distance between the second protruding bar and the third protruding bar. It is formed between the protruding bars, and the water discharge path is formed between the third protruding bar and the fourth protruding bar connected to the water pressure reducing path by each second path formed at a predetermined interval on the third protruding bar. However, each discharge slit through which the water is discharged is formed by perforating the drip hose in which the water discharge path is located in a long and wide width or short and narrow width depending on the location of the crop and the amount of water supplied by a dedicated knife jig.

The first to fourth protruding bars include those having the same cross-sectional area in contact with the base member to prevent deformation when attached to the inner circumferential surface of the drip hose.

The first passage includes an inlet slit formed in the base member of the water inlet passage and the second protruding bar formed at an intermediate position between the inlet slit.

The second passage includes at least one formed on the third protruding bar on one side or both sides of the first passage as a starting point.

The dedicated blade jig includes a perforated table, each perforated blade having a different length and width under the perforated table, wherein each perforated blade is integrally or detachably formed on the perforated table.

By making the location of the discharge of water also possible by the perforation of the dedicated blade jig, the production is simple and quick, as well as the effect that mass production can be performed smoothly without any defects, and the water supply to crops is reduced. As it is done accurately and appropriately, it has the effect of maximizing the cultivation efficiency of crops.

In addition, by making it possible to prevent deformation due to attachment of the inner surface of the drip hose, pressure reduction and water supply in the drip hose can be smoothly performed, and high reliability of the product can be secured.

Fig. 2 is a longitudinal cross-sectional view according to Fig. 1;
3 is a plan cross-sectional view and a partially enlarged view illustrating the drip strip according to FIG. 1 .

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, and the present invention is not limited or limited by the embodiments.

1 is a partially enlarged perspective view and a partially enlarged view for explaining the present invention, FIG. 2 is another longitudinal cross-sectional view in FIG. 1, and FIG. 3 is a flat cross-sectional view and a partially enlarged view showing a drip strip according to FIG.

As shown, the conventional drip hose has a strip-shaped strip drip so that it can be discharged by maintaining a constant discharge pressure of water by flexibly responding to the increase or decrease of the flow rate according to the supply pressure fluctuation of water, which is the fluid supplied to the inside. It is used attached to the inner peripheral surface.

The strip drips provided in such drip hoses are generally formed in a continuous repeating unit drip shape having a water inlet area, a water pressure reduction area and a water discharge area.

However, as described in the technical part that is the background of the invention and the problem to be solved, the strip-shaped drip drip provided in the conventional conventional drip hose is a very cumbersome work process in which the technical configuration of water inflow and pressure reduction in the drip hose is quite cumbersome. Of course, it has the disadvantage of having a complex structure.

And above all, the biggest problem in the drip hose to which the conventional strip drip is applied is that the position of the discharge hole through which water is discharged cannot be changed, that is, the discharge hole is formed in a position coincident with the discharge space of the strip drip, so the position of the discharge hole It has the disadvantage of being quite cumbersome and inconvenient to plant a crop in the field or to install a drip hose by adjusting the location of the discharge hole according to the location of the crop.

In addition, if the planted crops are not planted at a certain distance, there is also a disadvantage in that water is not properly supplied.

According to the present invention, the structure for decompression in the drip hose has a minimal and simple structure in the form of a bar, and the inflow of water is made appropriately according to the pressure in the drip hose, and is formed in the drip hose according to the position of the crop. The point of discharging water is also to provide a drip hose that can be made by the perforation of the dedicated blade jig.

The drip hose (1) according to the present invention is a strip-shaped strip drip ( 10) has a technical configuration that is attached to the inner circumferential surface by a fusion method or the like.

The strip drip 10 attached to the inner circumferential surface of the drip hose 1 is an elastic material that can be deformed and restored in shape by the water pressure of the water flowing along the inside of the drip hose 1, and is placed on the upper surface of the base member 12. Between the first and fourth protruding bars 14A, 14B, 14C, and 14D, which are formed to protrude in the form of a bar of a predetermined height to be attached to the inner circumferential surface of the drip hose 1 by fusion, etc. It has a technical configuration including a water inflow path 13 , a water pressure reducing path 15 , and a water discharge path 16 . The first to fourth protruding bars 14A, 14B, 14C, and 14D have the same cross-sectional area in contact with the base member 12 to prevent deformation when attached to the inner circumferential surface of the drip hose 1 it is preferable

For example, the strip drip 10 is the water discharged even when the water pressure of the water changes, such as when the pressure of the water flowing along the inside of the drip hose 1 is 1kg/cm2 and 2kg/cm2 By preventing the pressure difference from occurring almost, the discharge amount of the final discharged water is maintained substantially constant when the water pressure or flow rate of water flowing inside the drip hose is changed.

Moreover, the drip strip has a technical configuration in which the overall technical configuration is composed of a minimal simple structure in which water inflow and pressure reduction can be made by the first to fourth protruding bars protruding to a predetermined height on the upper surface of the base member.

As a result, manufacturing is made simple, and the resulting economic feasibility is excellent, as well as excellent productivity.

In the above, the base member 12 and the first to fourth protruding bars 14A, 14B, 14C, and 14C are integrally made of the same material. That is, when the water pressure or flow rate of the water in the drip hose 1 increases by a certain level or more, the strip drip 10 including the above components is deformed to further depressurize the water flowing through the water decompression region. Conversely, when the water pressure or flow rate of the water is reduced, the shape is deformed in the opposite direction to decrease the degree of decompression of the water flowing through the water decompression region. In this way, it is preferable that the strip drip is formed of an elastic material that can be elastically deformed so that the strip drip can be deformed in shape by the water pressure in the drip hose. That is, the strip drip 10 is preferably made of a material relatively softer than the material of the drip hose 1, and is made of any one of a material in which rubber is added to a conventional polyethylene resin, rubber, urethane, and vinyl. can be done In addition, in order to facilitate the fusion operation between the strip drip and the drip hose, when the strip drip is made of a material such as rubber, urethane, scale, etc., the material constituting the drip hose and It is desirable to allow a similar plastic-based material to be further coated.

In addition, the base member 12 provides a region in which the first to fourth protruding bars 14A, 14B, 14C, and 14D are formed, and has a thin plate shape having a thin thickness of about 0.3 to 0.7 mm. Preferably, the first to fourth protruding bars 14A, 14B, 14C, and 14D are also formed to protrude from the surface of the base member 12 to a thin thickness of about 0.3 to 0.7 mm. A water inflow region, a water pressure reduction region, and a water discharge region are formed between the first to fourth protruding bars, which will be described again below. The first to fourth protruding bars may be formed in a conventional quadrangle or trapezoidal shape, as well as the first protruding bar and the fourth protruding bar formed on one side and the other side of the base member due to the characteristics of their positions. It can be formed in a semi-trapezoidal shape of This is so that the upper surface of each of the protruding bars can be easily and firmly fused to the inner surface of the drip hose.

The water inflow path 13, which is a water inflow region, is formed between the first protruding bar 14A and the second protruding bar 14B, and a base member between the first to second protruding bars 14A and 14B. Each of the inlet slits (12A) is formed so that water flows in wide or narrow according to the difference in water pressure in the drip hose (1) at a predetermined interval in (12). The inlet slit may be formed by a conventional punching method or a blade on the base member, and has a length of about 3 to 7 mm and a narrow width in the middle of about 0.2 to 0.4 mm. In particular, the inlet slit opens when pressure is generated due to the supply of water in the drip hose due to the nature of the elastic material, and when water flows in and the pressure is released, the inlet slit is closed again.

As a result, water in the drip hose flows through the inlet slit into the water inflow path, which is the water inflow region, and is filled. It is introduced through the gap where the inlet slit is opened by the pressure applied by the pump in the drip hose. That is, when the water pressure in the drip hose is high, the inflow slit is widened so that water flows in quickly. On the contrary, when the water pressure is low, the inflow slit opens narrowly and the inflow of water slowly flows in. Here, as the inlet slit is formed on the base member of an elastic material, it is widened or narrowed according to the difference in water pressure in the drip hose.

The water decompression path 15, which is a water decompression area, is connected to the water inflow path 13 by a plurality of first passages 14B-1 formed at a predetermined interval on the second protruding bar 14B. It is formed between the second protruding bar 14B and the third protruding bar 14C. The first passage 14B-1 is formed in the second protruding bar 12B at an intermediate position between the inlet slit 12A formed in the base member 12 of the water inlet passage 13 and the inlet slit 12A. . The first passage is formed in the second protruding bar in the form of a conventional groove having a predetermined width from the second protruding bar to the surface of the base member in a recessed form, so that water is rapidly introduced from the water inflow path to the water pressure reducing path. formed in plurality.

In other words, after the water from the drip hose is introduced into the water inflow path through the inlet slit, the pressure is reduced while flowing into the water pressure reducing path through the plurality of first passages formed in the second protruding bar. That is, the pressure is reduced because the water in the drip hose directly flows into the water inflow path and flows back into the water pressure reducing path through the plurality of first passages while the water pressure is relatively high. As a result, it becomes the basis for discharging water at a constant pressure when discharging it.

The water discharge path 16, which is a water discharge area, is the first connected to the water pressure reducing path 15 by each of the second passages 14C-1 formed on the third protruding bar 14C with a predetermined interval therebetween. It is formed between the 3 protruding bar 14C and the fourth protruding bar 14C, depending on the location of crops and the amount of water supplied by the dedicated knife jig 20 to the drip hose 1 where the water discharge path 16 is located. Each of the discharge slits 1A through which water is discharged by being perforated with a long and wide width or a short and narrow width is formed. At least one second passage 14C-1 is formed in the third protruding bar 14C on one side or both sides of the first passage 14B-1 as a starting point. The second passage is formed in the third protruding bar in the form of a conventional groove having a predetermined width from the third protruding bar to the surface of the base member in a recessed form, and the water pressure-reduced in the water pressure reducing path can be smoothly transferred to the water discharging path. At least one is formed so as to be introduced. The water discharge path 16 is formed with a wider width than the width of the water pressure reducing path 15 between the third protruding bar 14C and the fourth protruding bar 14C, so that the pressure is primarily reduced in the water decompression path. After that, let the pressure be reduced again. This ensures that the water pressure or flow rate of the water flowing into the water discharge path through the second passage is constantly maintained, so that the water discharged through the discharge slit is also discharged at a constant pressure.

In the above, the discharge slit (1A) is perforated by the dedicated blade jig 20, and can be formed by perforating at a certain position, of course, in particular, in the drip hose (1) directly above the crops planted by the operator at will It can be formed by a dedicated blade jig. The discharge slit 1A is also cut in a predetermined length and width by the water pressure of the water flowing into the water discharge path 16, and can be cut in the same shape as the inlet slit, as well as a long and wide width depending on the amount of water supplied. In addition to being able to make an incision with the For example, in the case of crops requiring a large amount of water, the discharge slit is cut long and wide so that a large amount of water is discharged. For crops requiring a small amount of water, the discharge slit is formed short and narrow to produce a small amount of water is discharged and supplied.

In particular, the discharge slot (1A) is a condition that can be perforated by a dedicated blade jig to supply the required amount or the location where crops are planted, as well as in the field where crops are regularly planted. It may be provided by incision at regular intervals.

Here, the dedicated blade jig 20 is a perforated table 22 that can be held by the operator's hand or mounted on equipment such as a press, and each perforated hole having a different length and width in the lower portion of the perforating table 22 It includes a blade 24, wherein each of the perforated blades 24 is integrally or detachably formed on the perforated table 22.

In the above, it is preferable that the perforated blade is formed in an arc shape so that the perforation can be made smoothly when the discharge slit is perforated in the drip hose, and the detachment of the perforated blade from the perforating table is inhibited by the groove and the protrusion at the position corresponding to each other It can be formed detachably by a fitting method.

Accordingly, when the operator is in use, the discharge slit can be formed in the drip hose according to the position of the crop, and the position of the discharge slit can be accurately set according to the position of the crop.

In addition, when the position of the discharge slit is to be located at a constant position, a perforation table can be mounted on the equipment so that the discharge slit can be perforated at a predetermined position.

Accordingly, the present invention does not have a complicated technical configuration, but rather an inflow slit through which water in the drip hose flows into the base member of the strip drip, which is a minimal simple technical configuration, a water inflow path, a water pressure reducing path, and a water discharge path. By being formed between the fourth protruding bars, manufacturing can be performed simply and quickly, and mass production can be smoothly performed without occurrence of defects.

In addition, the structure in which the water in the drip hose is introduced is also a simple structure by the inflow slit formed in the base member, as well as the water discharged through the strip drip. By having , it has conditions that can maximize the cultivation efficiency of crops.
