{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 cultivating crops capable of preventing a bonded portion from dropping as well as fountain in both directions.

More specifically, according to the present invention, a reinforcing fused portion is further formed on the opposite side of a bonding portion on which a flow path is formed, so that both sides can be stretched and contracted evenly so that the fused portion of the flow- The present invention also relates to a drip hose for cultivating crops in which a drainage channel is formed in a reinforced fused portion so that fountains can be formed in both directions.

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 planted, seedlings are transplanted and water is sprayed onto the adjacent crops using a sprinkler or spray hose until the roots of the seeded crops are settled. The roots of the crops are activated and vinyl mulching is performed 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. 7, the vinyl film is folded, and the end portions in the longitudinal direction are fused while the inner side surfaces are overlapped with each other to form the adhesive portion 110. The flow path 120 is formed in a part of the adhesive portion, Or the 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, but the adhering portion 210 may be formed, And a flow path is formed in 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.

That is, as shown in FIG. 7 and FIG. 8, the upper joining portion in which the water is dripping out is relatively thick and the elasticity is inferior due to the joining of the two plies, but the lower unbonded portion is thinner than the joining portion, 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 conventional fractional hose has a problem in that water is founted only in one direction and vinyls are covered with the drainage water so that vinyl is fused around the drainage water when used for a long period of time, so that the drainage passage is clogged.

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

The present invention is not only capable of preventing an adhesion portion formed to form a drainage path for discharging water to be dripped from being damaged, but also for enabling bidirectional watering,

The two edges of the two long films 11f are adhered to each other by the first and second adhesive portions 11 and 12 serving also as a reinforcing band to form the shape of the hose having the flow path 10 in the longitudinal direction, Drainage passages 11w and 12w are formed in the second adhesive portions 11 and 12 so that water can be discharged in both directions.

The drip hose according to the present invention is similar to a conventional hose and discharges water by the drain line 11w. The drain line 11w can be modified in various ways, The unconnected portion is formed in the middle of the joining portion composed of the two lines of joining lines 11l as shown in FIG. 1 and used as the drainage passages 11w and 12w. One side of the drainage passages 11w and 12w is connected to the side of the oil passage 10 And the other end thereof is opened to the outside of the hose so that the water in the oil passage 10 can be discharged to the outside of the hose 100 through the oil channels 11w and 12w.

It is preferable that the first and second adhesive portions 11 and 12 have the same structure as possible.

That is, as shown in Fig. 1, the bonding line 111 formed on the first bonding portion 11 and the bonding line 121 formed on the second bonding portion 120 are formed in the same manner, and when the hose 100 is expanded and contracted It is preferable that the drainage passages 11w and 12w formed in the respective adhesive portions 11 and 12 are formed in the same shape and at the same interval as the drainage passages 11w and 12w The second adhesive portion 12 may be formed between the drain paths 11w formed in the first adhesive portion 11. The second adhesive portion 12 may be formed in the middle of the drain holes 11w formed in the first adhesive portion 11, So that water can be supplied evenly through the drainage passage 12w.

First, as shown in FIGS. 1 to 4, the first adhesive portion 11 is formed to be long in the lengthwise direction at the upward portion of the hose, and a part of the first adhesive portion 11 is not adhered, It plays a role.

As the first adhesive portion 11 is formed by adhering the two films 11f, the first adhesive portion 11 becomes thicker than other portions and the elasticity is lowered. Therefore, in the process of expanding and contracting the hose due to the rise of the outside air, the adhesive surface of the first adhesive portion 11 may be deteriorated due to the difference in the expansion / contraction ratio with other portions. To solve this problem, ) (Reinforcement bonding portion) is further formed.

In the conventional drop hose, both ends in the longitudinal direction of one film are bonded to form a drainage channel 11w. However, the present invention is configured using two films 11f so as to form the second adhesive section 12 have.

That is, one end portion of the two long films 11f are adhered to each other to form a first adhering portion 11 having a drainage passage 11w, and the other end portions are adhered to each other to form a 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 the channel 10 therein.

As described above, the first adhesive portion 11 can form a drain line by only one line of bonding lines, but two lines of bonding lines 11l are required to improve the dotting effect. , And a drainage passage 11w is formed between the bonding lines 111. [

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. More preferably, As in the first bonding portion.

However, as shown in FIGS. 2 and 3, the second adhering portion 12 of another example is formed of the second joining portion 12 with two rows of joining lines 12l, The water storage space 12s which can be stored is formed so that the water storage space 12s is filled with water so that the hose 100 can maintain the 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 12s of the second joint portion 12, water acts as a reinforcing means to prevent the hose from being bent sideways.

In addition, the present invention allows water to be discharged in both directions, and the water hole 12h is formed on the outside so that the water in the water accommodation space 12s can be discharged to the outside. That is, the drainage passage 12w is also formed in the second adhesive section 12, and the water supply hole 12h is formed through the inner and outer walls of the water receiving space to serve as the drainage passage 12w.

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.

5 and 6, a drip hose according to the present invention is characterized in that a film 1f is extended from an adhering portion to at least one of the first and second adhesive portions 11, Can be formed. Typically, the drop hose is installed on the crop-planted ridge and discharges the water to the soil adjacent to the root. When the drop hose is bent and gets out of the ridge, water is supplied to the unnecessary part, so it should be installed in the middle of the plant- For this purpose, it is preferable to form the fixed vane 13 as described above so that the fixed vane 13 can be fixed to the ground with the fixing pin.

The fixed blade 13 is formed long in the longitudinal direction of the hose by adhering a part of the film 1f in a state in which the part of the film 1f is exposed to the outside in the process of bonding the first and second adhesive portions 11 and 12, The pin can be plugged and fixed.

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.
