Description

Drip for buried irrigation hose

The present invention relates to a drip for an underground irrigation hose, and more particularly, it allows water to be divided into the drip and at the same time to reduce the amount of decompression. Buried type irrigation that effectively shuts off and allows water to flow only when the pressure exceeds the set pressure, and prevents the drip inlet hole from being clogged when the pressure of the irrigation hose is lower than the set pressure and at the same time prevents penetration of the roots of crops. It is about drip for hose.

In general, irrigation hoses used for growing crops have various types depending on the crops to be grown, but are usually used to supply water in a state where about 10 to 40 cm is buried from the surface of the land.

In this way, the underground irrigation hoses used buried in the land are arranged side by side at regular intervals to supply water to crops planted on a wide land, and each irrigation hose has a discharge hole for supplying water at regular intervals.

Moreover, since the underground irrigation hose buried in the ground has a long length ranging from several tens of meters to several hundred meters as long, it is a key to supplying water in a constant amount at all times.

Here, the supply of water is supplied to the crops as the water pressurized by a pump or the like is ejected from each discharge hole through the irrigation hose. The ball is equipped with each drip that ejects by reducing the water pressure.

As described above, in the prior art related to drip applied to the irrigation hose buried in the ground, as disclosed in Korean Patent Application Laid-Open No. 10-2001-0015750 (hereinafter referred to as 'prior art document 1'), the receiving member into which the membrane is inserted A technology for supplying water irrespective of variables of flow pressure in a conduit (corresponding to a 'water supply hose') has been proposed.

In addition, as disclosed in Japanese Patent Application Laid-Open No. 2016-73238 (hereinafter referred to as 'prior art document 2'), an emitter body including an emitter body and a film bonded to at least one surface of the emitter body to open and close Techniques have been proposed that stabilize the discharge amount of irrigation liquid by means of a system and reduce manufacturing cost due to the small number of parts.

In addition, as disclosed in Korean Patent Publication No. 10-1828597 (hereinafter referred to as 'Prior Art Document 3'), the cover body, A technology such as a drip for a water supply hose including a body and a control pad has also been proposed.

However, in Prior Art Documents 1 and 3, because the built-in membrane or control pad always has the ejection hole formed in the drip open regardless of the pressure in the irrigation hose, the drip located close to the pump supplies some large amount of water. Of course, it has the disadvantage that sometimes, the roots of crops block the vents of the drip, causing a setback in the supply of water.

Prior art document 2 has the advantage of a simple structure, but has the problems of prior art documents 1 and 3 as it is.

As shown, the irrigation hose 100 used in the cultivation of crops is used buried approximately 10-40 cm from the surface of the earth as described in the background technology of the invention, and in particular, each of the irrigation hose 100 Each drip 1 is attached and fixed to the discharge hole 110 so that a certain amount of water is discharged even in the discharge hole far away from the pump.

Here, in the case of the conventional drip drip used in the irrigation hose, regardless of the pressure in the irrigation hose, the jet hole formed in the drip is always open. Of course, sometimes the roots of crops block the vents of the drip, which has the disadvantage of disrupting the supply of water.

In addition, when the supply of water is stopped, as a part of the soil flows through the outlet hole of the irrigation hose as well as the outlet hole of the drip drip due to the pressure deviation, the outlet hole or the spout hole is blocked, so that water cannot be supplied properly.

The present invention allows the water to be introduced into the drip and at the same time the amount of decompression can be small, and when the pressure in the irrigation hose is less than the set pressure, the water inflow block is more efficiently blocked, and only when the pressure is higher than the set pressure The purpose of this invention is to provide a drip for an underground irrigation hose that allows the inflow of water and prevents the inlet hole of the drip from clogging when the pressure of the irrigation hose falls below the set pressure and at the same time prevents penetration of the roots of the crop.

The drip (1) provided on the bottom of each discharge hole 110 formed at regular intervals in the irrigation hose 100 buried in the ground according to the present invention to control the amount of water ejected is the body housing 10, the pad member ( 20) and has a technical configuration including a discharge member (30).

The main body housing 10 is formed with a plurality of inlet holes 12 through which water supplied through the irrigation hose can be dividedly introduced on one side of the bottom surface, and the plurality of inlet holes 12 are formed on the bottom surface of the inner side. It has a technical configuration including an inlet portion 15 in which an edge blocking protrusion 14 that is formed to protrude more upward than the bottom surface is formed to be located at.

In other words, it is preferable that the main body housing 10 has a rectangular parallelepiped-shaped upper surface in an open shape, and an upper edge surface is formed in a curved surface that is attached and fixed to the bottom surface of the discharge hole formed in the irrigation hose together with the discharge member.

In addition, it is preferable to form a plurality of inlet holes 12 of the inlet part 15 having different sizes, which is compared to the case where water is introduced at once through one inlet hole. By lowering the inlet pressure, it has a condition that can be stably introduced. Accordingly, it serves to primarily reduce the inlet pressure of the water flowing into the drip, as well as maintaining a constant pressure of the water.

In addition, the edge blocking projection 14 is opened and closed by the pad member 20 , and the upper surface of the upper surface is upwardly in contact with the pad member 20 from the outside to the inside so that a line contact can be made so that it can be opened and closed closely and quickly. The inclined surface 14A is formed. This is so that the pad member can be contacted quickly and sensitively according to a change in pressure. It is preferable that the height of the edge blocking protrusion 14 is formed to protrude from the bottom surface to a height at which the blocking protrusion of the pad member, which will be described later, comes into contact with it before it rises.

In addition, the passage space groove 16 through which the water introduced to the outside of the inlet part 15 and the opposite side of the inlet part 15 can flow is formed on the bottom surface. This is a structure in which water is supplied through a through hole formed in the pad member.

The pad member 20 rises when the set pressure in the irrigation hose 100 is higher than the set pressure on one side where the inlet 15 is located and falls below the set pressure to open and close the edge blocking sill 14 of the inlet 15 . The blocking protrusion 22 is formed to protrude upward, and has a technical configuration in which the through hole 24 is formed so that the water introduced to the opposite side of the blocking protrusion 22 passes.

In the above, it is preferable that the pad member is formed of a soft silicone material or rubber having excellent airtightness and elasticity on the bottom surface of the main housing housing and the bottom surface of the discharge member.

In addition, the through hole can control the amount of water flow, and by forming the through hole to a required diameter during manufacture, the flow amount of water can be adjusted. In this case, the through hole may be formed as one, of course, may be provided in plurality having different diameters, not shown. It is desirable to selectively apply this according to the conditions for supplying water to crops or the supply conditions.

In addition, the through hole 24 formed in the pad member 20 is located on the opposite side to the inlet part 15 of the body housing 10 and the ejection hole of the outlet member 30, which is the water introduced through the inlet part. As it flows into the passage space groove, it flows through the through hole located in the pad member on the opposite side and then flows to the opposite side with the decompression through the decompression path of the discharge member again, and then is ejected through the jet hole formed in the expansion space.

Accordingly, the water also has a condition that the water can be ejected while stably flowing by allowing it to be ejected after being decompressed along with the rotation, rather than being ejected directly from the inlet to the ejection hole. This is one of the technical components to prevent damage to the roots of crops because water is not ejected at high pressure when it is ejected.

In particular, the blocking protrusion 22 protruding upward to open and close the edge blocking projection 14 of the inlet 15 on the pad member 20 is in line contact with the edge blocking projection 14 in the irrigation hose. It is an important technical component that opens and closes sensitively according to the set pressure.

That is, the blocking protrusion of the pad member normally maintains a state of blocking the edge blocking sill of the inlet, which is a relatively long length of the irrigation hose. not. This is not to supply water first from the part close to the pump, but to prevent water from being supplied until the overall pressure in the irrigation hose rises to the set pressure evenly.

In this way, when the irrigation hose having a long length is filled with water and then exceeds the set pressure, the blocking protrusion of the pad member rises by a predetermined height from the edge blocking sill of the inlet, so that the water is injected while the water is discharged. have possible conditions.

In addition, when the operation of the pump is stopped due to the interruption of the supply of water, the pressure in the irrigation hose is momentarily reduced. It also plays a role in preventing the inlet hole from being blocked by the particles of soil or fine foreign matter introduced through the hole and the ejection hole.

Accordingly, the blocking protrusion of the pad member and the edge blocking jaw of the inlet respond sensitively to the pressure conditions in the irrigation hose to supply water uniformly and uniformly, as well as prevent the inlet hole from being blocked by soil or foreign substances. It is an important technical component.

The discharge member 30 is coupled and fixed to the inside of the body housing 10 to bring the pad member 20 into close contact with the bottom surface of the body housing 10 , and the irrigation hose 100 together with the body housing 10 It is attached and fixed to the bottom surface of each discharge hole 110 formed in the .

In addition, a pressure reducing path 32 is formed between the pressure reducing protrusions 33 alternately formed from the side where the through hole 24 of 0.5 to 2 mm depth is located to the other side so as to minimize the pressure reduction amount of water on the bottom surface, , on the expansion space 34 formed at the end of the decompression furnace 32, a jetting hole 35 positioned on the same line as the inlet 15 is formed, and the jetting hole 35 is an expansion space ( 34) is formed in the center of the protruding jaw part 36 formed at a height lower than the height of the expansion space 34 from the bottom surface, and the protruding jaw part 36 is ejected around the periphery of the protruding jaw part 36. It has a technical configuration in which at least one or more microchannels 36A connected to the ball 35 are formed. Preferably, the pressure reducing projection and the decompression furnace are formed to a depth of 0.5 to 2 mm and as low as possible from the bottom of the discharge member to minimize the amount of water to be decompressed so that the amount of sprayed water can be maintained uniformly and uniformly along with smooth decompression. When the depth is 0.5 mm or less, the supply of water is too little, and when it is 2 mm or more, a large amount of water is supplied, so it is preferable to form the depth as described above.

In other words, the discharge member 30 serves to cause the water that has passed through the body housing 10 and the pad member 20 to be finally ejected to the ground, and the pressure that has passed through the pad member is alternately formed. The pressure is reduced in the decompression furnace formed between the projections so that it is more stably ejected through the blast hole by the reduced pressure rather than the high pressure.

In particular, the at least one or more microchannels formed in the protruding jaws block the jetting hole by the blocking protrusion of the pad member when abnormal pressure is generated in the irrigation hose. It acts as an ejector.

Therefore, even when abnormal pressure occurs in the irrigation hose, the water supply to the crops is continuously and smoothly supplied.

Accordingly, the present invention can supply water more uniformly and uniformly according to the pressure in the irrigation hose having a relatively long length, and in particular, by preventing the inlet hole from being blocked by foreign substances even when the water supply is blocked, It is possible to secure high reliability of the plant, as well as to increase the cultivation efficiency of crops thereby.

On the other hand, since the irrigation hose is used in a state buried in the ground, sometimes the roots of crops flow into the inside of the drip and block the ejection hole of the drip, so in the drip of the present invention, the roots of these crops A technical configuration is also provided to prevent phenomena such as clogging of the vents.

A residual space groove 38 in which a part of the water remains so that the roots of cultivated crops do not flow into the ejection hole 35 side is formed on the upper surface of the discharge member 30 opposite to the ejection hole 35 is formed, The residual space groove 38 further includes a plurality of guide protrusions 39 formed at predetermined intervals.

In other words, the squirt hole is guided to a residual space groove in which a part of the water remains even if the roots of the crop are introduced through the drain hole of the irrigation hose due to the continuous jetting of water, and the induced crop roots are induced into a plurality of induction holes. As it is sandwiched between the protrusions, it is possible to prevent the vents from being blocked by the roots of the crop.

In addition, even if the water supply is interrupted, it is possible to prevent the vents from being blocked by the roots of the crops as the roots of the crops are guided toward the grooves of the residual space where a part of the water remains.

Therefore, in the process of supplying water through drip, the drip function is not lost due to the roots of the crop, and a long period of use can be secured.

In addition, the present invention also provides a technical configuration that can prevent the roots or foreign substances of crops from being fundamentally introduced into the drip (1).

That is, each discharge hole 110 formed in the irrigation hose 100 is generally formed in a circular or rectangular oval shape, which can easily introduce the roots of crops.

However, as shown in FIG. 6 , the discharge hole 110 in the present invention has a plurality of slits (slit, 110A) in the form or a plurality of slits to prevent the roots of crops from flowing into the irrigation hose 100. Any one of the micro-pores (110B) is formed.

In other words, by forming the discharge hole through which the water is discharged in the form of a plurality of slits or micropores, it is possible to establish a condition that can fundamentally block the inflow of the roots of crops without causing a problem with the jetting of water.

Accordingly, by applying a simple technical configuration to the discharge hole of the irrigation hose rather than a complicated technical configuration, the roots of crops are fundamentally blocked from flowing into the irrigation hose. It also has conditions that can increase the efficiency of use relatively.

7 is a bottom perspective view for explaining another embodiment of the discharge member of the present invention.

As shown, in the above configuration, a technical configuration capable of maximizing the decompression efficiency in the decompression furnace of the discharge member is provided.

Between each of the pressure reducing protrusions 33 formed on the lower surface of the discharge member 30 or in the decompression path 32, each auxiliary pressure reducing protrusion 33A can further increase the decompression efficiency due to frictional resistance due to contact with the water to be decompressed. ) is further formed.

In the above, each auxiliary pressure reducing protrusion is provided between each pressure reducing protrusion as well as on the pressure reducing path, and a pin in a direction orthogonal to the direction in which water flows or inclined in the form of a pin so as to have a high frictional resistance when in contact with water. Or it is preferable to form a piece shape.

In other words, the decompression efficiency of the water flowing while the pressure reduction is performed in the decompression protrusion or the decompression furnace further increases due to frictional resistance due to contact with the auxiliary decompression protrusion again.

As a result, the water that is ejected through the ejection hole formed in the protruding jaw is more stably ejected, thereby providing a condition for smoothly supplying water.

In addition, it provides a technical configuration in which water in the expansion space can be introduced more smoothly into the micropore that supplies water even when the jet hole is blocked by the blocking protrusion of the pad member due to abnormal pressure in the irrigation hose.

It is preferable that the microchannel 36A is formed so that the outer periphery side of the protruding jaw part 36 is wide and the ejection hole 35 side is narrow.

That is, even in a state in which the jet hole is blocked by the blocking protrusion of the pad member, the water in the expansion space flows more smoothly into the micro-furnace than the micro-furnace having the same width through the portion formed wider toward the outer periphery of the protruding jaw. Water supply can be discharged continuously and smoothly.
