The present invention relates to a double hose for supplying water to various crops, and more specifically, the outer hose and the inner hose is composed of a different material and the fiber material and vinyl material, and the size and number of water holes according to the hose length The present invention relates to an agricultural double hose configured to maintain a uniform amount of water over the entire length by correcting a drop in water pressure.

Conventional fountain hose is a structure in which water holes of uniform size are formed at uniform intervals on the upper surface of the body of the hose made of vinyl material, and the water is supplied by supplying high pressure water using a pump, etc. It consists of supplying streams of water to the crops.

However, this method has a problem that the high pressure water of the pump supplied to the hose decreases away from the pump, so that the amount of water ejected from the front part and the rear part of the hose is different so that the water cannot be evenly sprayed on the crop. The problem is that the water supply is stopped around the blocked area due to the inclusion of foreign matter or soil attached to the outside or a small stone to block the water hole.

In addition, the main material of the hose is made of a plastic film material or a vinyl material has a disadvantage that the durability is lowered because the hose is damaged by the breakage caused by a sharp material and the larvae to eat vinyl.

In this case, a relatively small diameter internal hose is embedded in the large external hose so that the water supplied to the internal hose is supplied to the external hose through the spout of the internal hose, and the water of the external hose is spouted to the outside through the spout of the external hose. A part of the inner circumferential surface of the outer hose and a part of the outer circumferential surface of the inner hose are joined to each other by PE resin, and a double hose is used in which a plurality of outlet holes are formed in the outer hose and the inner hose, respectively.

However, the outer hose and the inner hose of the double hose are made of the same material of plastic film or vinyl material, and when the water is not supplied for a long time, the outer hose and the inner hose are stuck to each other and become flat, so that the hose is flat when used again. There was an uncomfortable disadvantage to separate each. In addition, the mulching film that is covered on the top of the hose stuck to the water hole formed in the upper portion of the outer hose to prevent the water ejection, making it difficult to supply water to the crop.

The present invention is designed to solve the problems caused by the lack of water supply by ensuring a uniform amount of water supply over the entire length of the fountain hose, the present invention is to determine the size and spacing of the water hole formed in the hose The pump is formed differently according to the distance from the hose point to which the pump is connected so that a certain amount of water is ejected regardless of the hydraulic pressure drop according to the length of the hose.

In addition, the present invention is composed of a non-woven fabric and a vinyl material of the outer hose and the inner hose respectively, so that the outer hose and the inner hose does not stick to each other, the outer hose is scratched by a sharp object or pests are not eaten, The foreign material and small boulder, or the soil or mulching film by the fine hole of the fiber material without the blockage of the water hole to be ejected to enable the water.

The present invention is composed of an outer hose made of a fiber material in which water supplied to the inside is discharged to the outside and a diameter embedded in the outer hose, and is a waterproof synthetic resin material, the outer peripheral surface on one side of the inner circumferential surface of the outer hose One side is joined, and a plurality of water holes are formed in the upper portion, and the size and distance of the water holes increases as the distance from the hose point portion connected to the pump increases the area of the water holes per unit length, thereby increasing the inside of the external hose. An agricultural double hose is provided, characterized in that the amount of water discharged is made up of an equal internal hose.

The fiber material constituting the outer hose is strong and flexible against pests, durable against external shocks, and has micro holes that are hydrophilic. The water channel from the inner surface to the surface is secured. One of the water is discharged into the droplets to evenly moisten and wet the outside soil.

Synthetic resin material constituting the inner hose is excellent in waterproof effect, light weight, flexible and easy to use, and forms a water hole to eject the water supplied to the outer hose.

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

1 is a view showing the basic structure of the present invention, the embodiment is composed of a non-woven outer hose 11 formed of a cylindrical shape, a cylindrical material of a relatively small diameter and a flexible plastic material than the outer hose (11) The inner hose 12 may be formed of a waterproof synthetic resin material such as a plastic film material.

The inner hose 12 is formed with a water passage 12a through which water can pass, and the water passage 12a can be continuously formed by punching in a circular shape, and it is hardened to continuously form a linear hole. Can be formed.

In the hose hole 12a of the embodiment, the hose point portion 10a connected to the pump 20 reduces the size of the hole 12a and widens the space of the hole 12a, from the hose point portion 10a. As the distance increases, the size of the water hole 12a is increased and the distance between the water hole 12a is narrowed. As the distance from the hose point portion 10a increases, the area of the water hole 12a per unit length increases to increase the amount of water ejected. It has a configuration to be made evenly over the whole fountain hose (10).

The above configuration is to maintain a constant amount of water ejected per unit length by reflecting the water head difference at the starting point and the end point of the hose due to the friction loss head and the shape loss head in the hose 10. The loss is proportional to the length of the pipe and the square of the flow rate, the flow rate is inversely related to the square root of the length, and the flow rate is proportional to the cross-sectional area of the flow hole 12a. Therefore, as the water flowing along the inner hose 12 becomes farther from the hose, the head drop due to the water discharged through the continuous water hole 12a and the loss head caused by friction occur simultaneously. In the amount of water escaped through the through hole (12a) is significantly reduced.

However, in the hose point of view portion 10a as in the example of the present invention, the size of the water passage 12a is made smaller and the distance between the water passages 12a is increased. Increase the total area of the water hole 12a per unit length by reducing the distance between the water holes 12a and increasing the total area of the water holes 12a so that the water discharge of the internal hose 12 is made to coincide with the beginning and the end. The outer hose 11 can be inflated by supplying the outer hose 11 constantly from the beginning to the end. The inner hose 12 facilitates water discharge of the outer hose 11 by filtering soil, sand or various foreign matters contained in agricultural water and supplying water to the outer hose 11.

The outer hose 11 is filled with the water discharged to the inner hose 12 is filled with a bulging inflated to form a cylindrical structure, when the water is supplied to the inside when the water is discharged to the outside by pressure. The droplets can be moistly supplied to the crops 100, and even after the water supply of the pump 20 is stopped, water remaining in the outside is discharged into the crops 100 little by little through the fine holes of the nonwoven fabric.

The nonwoven fabric of the embodiment has a fine hole treated with a hydrophilic treatment to secure a water passage through which water passes from the inner surface to the surface, and easily discharges water. Fiber materials can be used.

The outer hose 11 and the inner hose 12 are manufactured separately and manufactured by bonding one part of one side with an adhesive.

Figure 2 is a small size in the hose point portion 10a connected to the pump 20 in the shape of the water hole 12a of the inner hose 12 is changed according to the length of the hose 10, hose point portion 10a As the distance from the () increases, the area of the water hole 12a per unit length is increased by increasing the size of the water hole 12a, and FIG. 3 shows that the space of the water hole 12a of the inner hose 12 is greater than that of the hose. In the hose point portion 10a connected to the pump 20 in a shape changed according to the length of 10, the gap between the water passages 12a is widened, and the distance from the hose point portion 10a is increased. ) Shows that the area of the water hole 12a per unit length is increased by narrowing the space between the holes), and by varying the size and distance of the water hole 12a, the water supply to the external hose 11 is provided. You can make it constant from point to point.

The most preferable structure is to reflect the reduced pressure (water head difference) of the water pressure in each water hole 12a to reflect the size of each water hole 12a or the distance between the water holes 12a. In order to solve this problem, the present invention divides the length of the inner hose 12 into several zones so that the manufacturing process of the fountain hose 10 needs to be very complicated and involves a precise manufacturing process. The size and distance of the same to the area farther from the hose point 10a suggests a configuration that increases the area of the through hole 12a per unit length.

For example, the total length of the inner hose 12 is divided into three, divided into a, b, and c zones, and a plurality of water holes 12a belonging to each zone are formed to have the same size and the same distance, and the hoses are divided by zones. As the distance from the view point increases, the size of the water passage 12a is increased or the interval is narrowed, so that the amount of jet water per unit length is approximated over the entire area.

The above embodiment can be easily produced by maintaining the size or spacing of the water supply hole (12a) the same for each zone, the longer the length of the inner hose 12 is divided into divided areas to make a more even water supply The method of dividing the divided section is made in the process of forming the inner hose (12).

Figure 4 is to explain the relationship between the flow rate change according to the length of the inner hose 12, the cross-sectional area and the flow rate of the water hole (12a) by the present design A ₁ , The total area of the water hole (12a) in the b area is A ₂ , and the total area of the water hole (12a) in the c area is A ₃ , and the head loss along the length and the head drop depending on the quantity of water exited through the water hole (12a) are reflected. is the flow rate of the flow rate of a zone relative to the flow rate with the difference V _1, b area respective sections V _2, c Assuming that the flow rate of the region V ₃ the total amount of water supplied via a fountain hose (10) Q = Q1 + Q2 + Q3 = A ₁ V ₁ ² + A ₂ V ₂ ² + A ₃ V ₃ ² and in order to maintain the same amount of outflow water in each zone, Q1 = Q2 = Q3, that is, A ₁ The relationship V ₁ ² = A ₂ V ₂ ² = A ₃ V ₃ ² is established.

Since the flow velocity is reduced by head loss, V ₁ > V ₂ > V ₃ relation, so the total area of the through holes 12a formed in each zone becomes A ₁ <A ₂ <A ₃ , thereby maintaining the same flow rate. .

The present invention is to increase the area of the water hole 12a by the number of heads generated along the length from the time of the hose to equalize the amount of water flowing out, the more the water per hole per unit length away from the hose starting point (10a) By increasing the area of (12a), it is possible to eject the same amount of water over the entire length.

5 is a view showing the use state of the present invention, the hose 10, covering the mulching film 200 in order to prevent weeds from growing after punching the mulching film 200 to plant the crop 100 to be. Even if the mulching film 200 covers the upper portion of the outer hose 11, the water supplied to the inner hose 12 is discharged to the outer hose 11 and filled up and expanded by water pressure and covered by the mulching film 200. Regardless of the water discharged through the fine holes of the outer hose 11 made of a non-woven fabric is easy to supply water to the crop (100).

The present invention makes it possible to supply water evenly over the entire length of the double hose by varying the hole area per unit length of the inner hose, so that the water can be supplied evenly over the entire length of the double hose. Reduced pump operation has the effect of efficient energy consumption.

In addition, the present invention is composed of a non-woven fabric in which the external hose is formed with a fine hole as a whole, the water contacting the inside is passed through the outside, the water is sprayed in the overall length of the hose can be grown uniformly to increase the yield Since the inner and outer hoses are made of different materials, they are not attached to each other for easy management.The outer hose made of non-woven fabric prevents damage from sharp objects or pests, so it is not necessary to replace the hoses frequently. There is an advantage to prevent the economic loss of the purchase.
