Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sprinkling tube used for agriculture or gardening.

[0002]

[Prior art]

 Automatic sprinkling using a sprinkler, etc. is convenient, but it requires equipment costs and there are some areas where sprinkling does not reach.So far, it was cheap and preferable to sprinkle water from the sprinkling holes using a sprinkling tube laid in the ridge. there were. However, since water could not be placed stably due to twisting of the tube due to water pressure, wind, etc., water sprinkling often did not reach the standard value, and maintenance was troublesome.

[0003]

[Problems to be solved by the device]

 Therefore, the present invention provides a water sprinkling tube that uses an inexpensive water sprinkling tube and can prevent the tube from twisting due to water pressure and movement due to wind, etc., which does not require maintenance and ensures stable water sprinkling.

[0004]

[Means for Solving the Problems]

 For this reason, the present invention has a structure in which a large number of water sprinkling holes are provided through a plastic tube and a locking projection is provided on the outer periphery along the tube. In addition, the locking projections may be provided on both sides, and the water spray holes may be transparently provided on the upper half surface of the tube.

[0005]

[Action]

 By connecting to a water injection part such as a faucet or hose and injecting water, water is sprinkled from each water spout hole and discharged, and since the tube is reinforced by a locking projection protruding on the outer circumference, It is possible to prevent the tube from twisting due to, and to prevent the movement due to the wind by locking the locking projection to the ground.

[0006]

【Example】

 Hereinafter, illustrated embodiments of the present invention will be described. In the water sprinkling tube of this example shown in FIGS. 1 to 3, reference numeral 1 denotes a polyethylene tube, which has a connection opening 11 formed at one end with the hose connector 4 and the other end opening 12 closed with an obturator 5. A large number of water sprinkling holes 13 having a diameter of 300 μm are formed in the upper half. The sprinkling holes 13 can be easily provided by piercing and melting the heating needle while the tube 1 is inflated.

A locking projection 14 is provided on the outer periphery of the tube 1 so as to project in the center of both sides along the tube. As shown in the phantom line in Fig. 3, the longitudinally shaped both sides of the tube are thermocompression-bonded while being pinched by the upper and lower rollers. The protrusions 14 are formed by thermocompressing while holding the upper and lower rollers, and the outer diameter of the tube 1 is about 3 cm, the thickness of the tube 1 is about 2 mm, and the width of the protrusions 14 is about 8 mm.

In the use of this example, by connecting the connection opening 11 to the connector 4 of the hose attached to the faucet and injecting water, the water is splashed from the respective water spray holes 13 by the internal pressure of the water and is discharged. Therefore, in this example, the tube 1 is reinforced by the locking projections 14 provided on the outer periphery to prevent the tube 1 from being twisted, so that the tube 1 can be prevented from being twisted due to water pressure. The stopping action also prevents movement due to wind.

Therefore, according to this example, the tube 1 can be stably arranged by connecting the locking projections 14 in series, and the water sprinkling position can be stabilized. When not in use, it becomes flat as shown in Fig. 4 and can be wound up.

Although the present example is configured as described above, the present invention is not limited to this. For example, the plastic material of the tube may be nylon or the like, or may be a plastic material reinforced with a wire material. Further, the formation thereof is not limited, and two plastic composite films or sheets are opposed to each other and both longitudinal end portions are adhered by heat sealing or the like, so that the both end adhering portions are protruded from each other as shown in FIG. The tube can be formed. Alternatively, as shown in FIG. 6, it is possible to form a tube having the adhesive portion as the protrusion 14 by adhering the end portions in the longitudinal direction obtained by bending and combining a single plastic composite film or sheet by heat sealing or the like. According to these, it is possible to easily perform the perforating process of the water spray holes before the bonding.

Further, the shape, width, number and protruding position of the locking projections may be appropriate, and they may be formed as shown in FIGS. 7 and 8. The projection surface is smooth, and the projections and depressions are embossed. But it's okay. The thickness and length of the tube are arbitrary, and the size of the water sprinkling hole is also arbitrary, but a diameter of 50 to 1000 μm is appropriate, and the transparent position of the water sprinkling hole is also appropriate.

[0012]

[Effect of device]

 According to the present invention, the tube is reinforced by the locking projections provided on the outer periphery to prevent the tube from being twisted, so that the tube can be prevented from twisting due to water pressure, and the locking effect of the projection can prevent movement due to wind or the like. A stable watering condition can be secured. According to the second aspect, the directionality of water sprinkling can be secured.
