Abstract

The present invention relates to a drip hose for growing crops. According to the present invention, a resistance part which resists water flow in an irrigation flow channel so that irrigation is performed through all irrigation flow channels under a condition that the hose is completely filled with the water supplied. Therefore, irrigation is uniformly performed on all areas. Moreover, a reinforcing fused portion is additionally formed on a side opposite to a bonded portion on which the irrigation flow channel is formed; thus, both sides of the hose can be uniformly stretched. Consequently, water leakage, caused when only a side of the hose is stretched and the fused portion where the flow channel is formed is separated, can be prevented.

Description

{Drip Hose for Growing Plant}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a drop hose for cultivating crops, and more particularly to a drop hose for growing crops in which water can be irrigated evenly.

More specifically, the present invention forms a resistance portion which is resistant to the flow of water in the irrigation channel, so that the water supplied to the inside of the hose is filled through the entire irrigation channel in the state where the water is filled to the end of the hose, The reinforcing fused portion can be further formed on the opposite side of the bonding portion on which the irrigation channel is formed so that the both sides can be stretched and contracted evenly so that the fused portion of the forming portion can be prevented from leaking The present invention relates to a drop hose for growing a crop.

Generally, when cultivating crops, hose is piped or water is supplied by spraying, and the method of supplying water according to the growing period of the crop is different. For example, when seedlings such as strawberries are cultivated, seedlings are transplanted and water is sprayed on the adjacent crops using a sprinkler or spraying hose until the roots of the seeded crops are settled. The roots of the crops are activated, and vinyl mulching is carried out The water is dropped by using a drop hose.

Patent literatures 1 to 3 are techniques related to such dot hoses.

These drip hoses are usually constructed by overlapping both longitudinal edges of a long vinyl film and then fusing them to form a flow path through which water is sprayed to a part of the bonded portion.

As shown in FIG. 5, the vinyl film is folded, and the end portions in the longitudinal direction are overlapped with each other in the overlapping state to form the adhesive portion 110. The flow path 120 is formed in a part of the contact portion, Or an end portion in the longitudinal direction may overlap the inner surface and the outer surface, as shown in FIG. 6, and then the overlapped portion may be adhered to form an adhering portion 210, and a channel 220 And a flow path is formed at an intermediate portion of the hose.

In the conventional drip hose made in this way, since the joint is formed on only one side, there is a problem that when the hose temperature rises and the connecting hose is increased, water leaks due to the difference in the expansion ratio between the joint and the other parts.

In other words, as shown in Figs. 6 and 7, the upper joining portion in which the water is dripped out is two layers are joined to each other to be relatively thick and low in elasticity, but the lower unbonded portion is relatively thin and elastic There is a problem that the joint portion is distorted during the process of expanding and contracting the hose by the heat, so that the joint portion is detached or deformed and the water flows out unintentionally.

In addition, the irrigation water flow paths 120 and 120 'formed in the conventional irrigation hose must be irrigated at the same time in the whole hose through the flow path so that irrigation water can be uniformly distributed to all the plants. However, in the conventional hose, the water is introduced into the hose inlet, and at the same time, the irrigation channel of the portion to be introduced is opened, and the irrigation water starts to flow to the plant of the inflow portion. There is a problem that the water is not irrigated uniformly because the irrigation water is formed through the irrigation water flow path formed at the opposite side end portion while being pushed up to the opposite end of the irrigation water. In other words, the plants at the end of the hose are largely irrigated while the plants at the opposite end have relatively small irrigation water, so some of them are rotten by the supply of excess water and the plants of the opposite side are water There was a problem of failing due to lack.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a drip hose for plant cultivation in which irrigation water can be uniformly distributed to all the plants in a place where hoses are disposed.

In detail, the present invention is characterized in that a resistance portion for suppressing the discharge of water is formed in the inside of the irrigation water channel so that water is sufficiently filled in the inside of the hose so that irrigation water can be simultaneously generated in all the irrigation water channels after the pressure is formed, A reinforcing and adhering portion is formed on the opposite side of the joint portion from which the water is discharged to uniformly extend and contract in the longitudinal direction so that the fused portion where the flow path is formed can be prevented from leaking The present invention relates to a hose for cultivating a crop.

In order to achieve the above object, the present invention provides a drop hose having a water supply channel for discharging water to a crop, wherein at least one resistance portion is further formed inside the water supply channel for discharging water, And the irrigation water flow path is formed between the first adhering portions of the two films which are adhered to each other, and the irrigation water flow path is formed between the opposite end portions of the first adhering portion The two adhesive portions are adhered to each other in the longitudinal direction so that the two films form a circular cylinder to form a channel so that the two adhesive portions serve as reinforcing portions on the opposite sides.

Further, in the present invention, it is preferable that the second adhesive portion is joined by at least two lines of joint lines so that a water channel is formed between the joint lines, one side of the water channel is opened to the channel side and the other end is opened to the outside of the hose.

The present invention is characterized in that at least one resistance portion is formed in the water flow path so that the water discharged through the water flow path is discharged only when the pressure inside the hose rises by a predetermined value or more, I can do it.

That is, the irrigation channel is opened and the irrigation water is provided only when water is sufficiently filled in the water from the water supply part to the opposite side end of the hose, so that irrigation water can be uniformly generated in all irrigation channels formed in the entire hose, So that irrigation can be performed evenly.

Further, according to the present invention, a reinforcing and adhering portion is formed on the opposite side of the adhering portion so as to have the same expansion / contraction ratio as that of the adhered portion for forming the flow path, so that the entire hose is expanded and contracted in the longitudinal direction evenly, There is an effect that can be prevented.

In addition, a space for storing water is formed in the reinforced and adhered portion so as to fill the water, so that the hose has an effect of providing straightness.

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

The present invention is characterized in that a resistance portion 10 is formed inside a water flow path for discharging water by dripping water so that water passing through a water flow path is opened only when water is filled in the hose and pressure is applied, .

The resistance portion 10 formed in the drop hose according to the present invention may be formed in various structures as shown in FIG. That is, as shown in Fig. 5 (a), concavities and convexities are formed in the shape of a sinusoidal toward the inside of the flow path on the inner wall of the irrigation water flow channel 11w, And at least one or more engaging jaws may be formed. Further, as shown in Fig. 5 (c), a tonneau may be formed inside the flow path, but the flow path itself may be formed in a meandering shape.

In addition, the dot hose of the present invention is another feature that the bonded portion is prevented from being damaged and the channel is prevented from being damaged. That is, the drop hose of the present invention forms a second adhesive portion on the opposite side of the portion where the water channel 11w is formed, and is symmetrical with respect to the center at the center, and the adhesive portion is formed to reduce the longitudinal stretchability of the hose.

As shown in FIG. 1 to FIG. 3, the adhesive portion of the film 11f to form the irrigation water passage 11w is a first adhesive portion 11, And the irrigation channel 11w is formed without adhering a part of the irrigation channel 11w.

As the first adhesive portion 11 is made by adhering the two films 11f, the first adhesive portion 11 becomes thicker than the other portion and the elasticity is lowered. Accordingly, in the process of expanding and contracting the hose in the longitudinal direction when the external temperature rises, the bonding surface of the first bonding portion 11 may be deteriorated due to the difference in expansion / contraction ratio with other portions. To solve this problem, And a first bonding portion 12 (reinforcing bonding portion) is further formed.

In the conventional drip hose, both ends in the longitudinal direction of one film are adhered to form the irrigation channel 11w. However, in the present invention, the two films 11f are used to form the second adhering portion 12 .

That is, one end of the two long films 11f are adhered to each other to form a first adhering portion 11 on which the irrigation channel 11w is formed, and the other end is adhered to each other to form the second adhering portion 12. [

The first and second adhesive portions 11 and 12 are formed on opposite sides of the hose so that the longitudinal expansion and contraction ratio of the hose is equal to both the upper and lower sides. The lengthwise ends of the two films 11f are adhered to each other by the first and second adhesive portions 11 and 12 to form a long hose having a channel therein.

As described above, the first adhesive portion 11 is a method for forming the irrigation water flow path 11w. However, the irrigation water flow path can be formed by only one line of the connection line. However, 11l, and the water supply flow path 11w is formed between the bonding lines 111. As shown in Fig.

In the same way as the conventional drop hose of the water supply flow path 11w formed in this way, one side is opened to the flow path side and the other end is opened to the outside of the hose so that the water introduced from the flow path gradually flows to the outside of the hose through the water flow path 11w Is discharged.

As described above, since the first bonding portion 11 is formed of two rows of bonding lines 111, it is preferable that the second bonding portion 12 is also bonded to at least two rows of bonding lines 121. When the second joining portion 12 is formed by the two lines of joining lines 12l, a water receiving space 12w in which water can be stored may be formed between the two joining lines 12l, When the space 12w is filled with water, the hose can maintain its straightness.

That is, when the water is completely discharged from the inside of the drop hose of the present invention, the drop hose is bent laterally out of its original position by a small external force. However, as described above, when water is filled in the water receiving space 12w of the second joint portion 12, water acts as a reinforcing means to prevent the hose from being bent sideways.

In order to fill the water receiving space 12w with water, the water receiving hole 12h should be formed in the wall facing the inner wall of the water receiving space. However, if the water hole 12h is formed too much, the water in the water passage is discharged and the water in the water receiving space 12w can not be discharged. Therefore, the number of the water hole 12h is relatively small, So that the water introduced into the water receiving space 12w is not discharged for a long time.

In the drip hose for cultivating a crop according to the present invention having the above-described structure, the first and second adhesive portions 11 and 12 can be bonded by a heat fusion method. However, when the film itself is melted and adhered by the heat welding method, the film itself may be damaged, and the adhesive portion may be weakened and easily separated or deformed. Therefore, it is preferable to use a separate adhesive means.

As a preferred method of bonding the first and second adhesive portions 11 and 12, the melted synthetic resin is applied in two rows, followed by bonding and cooling, or using hot melt. In the hot-melt bonding method, a hot-melt having a predetermined thickness is laminated between two films, and heat is applied to melt and adhere the hot-melt between the two films, thereby preventing damage to the film and reinforcing the strength of the adhesive .

Such a hot-melt adhesive can be selected from a previously developed solid adhesive which is melted by heat and solidified within a few seconds to generate an adhesive force, and a detailed description thereof will be omitted.
