  However, in the conventional irrigation apparatus described above, when the tapered nozzle tube is pierced into the soil, the water injection hole drilled in the nozzle tube is directly closed by the soil and blocked by the soil. Therefore, if the diameter of the water injection hole is made small in order to slow the water injection speed to the soil, water injection into the soil becomes impossible from the beginning, or it stops during the water injection. Will cause a problem to do.

  In order to avoid this problem, if the hole diameter of the water injection hole is increased, the water injection speed from the water injection hole becomes too high.

  This invention makes it the technical subject to provide the irrigation apparatus which eliminated these problems.

In order to achieve this technical problem, claim 1
“In the irrigation device in which a nozzle tube with a tapered taper is installed in a container for irrigating the soil, and a water injection hole is drilled in the nozzle tube.
A water-permeable porous body was attached to a portion of the nozzle tube where the water injection hole was opened, so that the water injection hole could be closed with the porous body. "

Claim 7
“In any one of claims 1 to 6, the nozzle tube is detachably attached to the container.”
It is characterized by that.

  According to claim 1, since the water injection hole in the nozzle tube is closed by the porous body, when the nozzle tube is pierced into the soil, the porous body comes into contact with the soil. It can be avoided that the water injection hole is blocked by the soil.

  As a result, since the liquid in the container penetrates the porous body from the water injection hole in the nozzle tube and is injected into the soil, water injection into the soil becomes impossible from the beginning or during the water injection. It can be surely prevented from being interrupted, and water can be gradually and slowly poured into the soil.

  In this case, since the porous body is made into a fibrous body as described in claim 2, water is poured into the soil through the capillary of the fibrous body. It can be done slowly and slowly.

  Further, according to claim 3, 4 or 5, there is an advantage that the porous body can be easily and surely and firmly attached to the nozzle tube, and particularly, claim 3 or 5 According to this, it is possible to reliably prevent the porous body from moving with respect to the nozzle tube.

  Furthermore, according to claim 6, water or liquid such as liquid fertilizer can be appropriately supplied from the spout while the irrigation device of the present invention is stuck into the soil.

  According to claim 7, in addition to being able to manufacture the pipe of the container separately, the nozzle tube can be replaced with a new one or with a different irrigation rate to the soil, The container can be replaced with a new one or with a different internal volume.

It is a figure which shows 3rd Embodiment. It is a figure which shows 4th Embodiment. It is a figure which shows 5th Embodiment. It is a figure which shows 6th Embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  In these drawings, reference numeral 1 denotes a container formed of a synthetic resin into a hollow cylindrical shape.

  One end (upper end) of the container 1 is opened so as to serve as an upward spout 2 for injecting liquid such as water or liquid fertilizer into the container 1, and the other end (lower end) of the container 1. The screw socket portion 3 is integrally provided.

  Reference numeral 4 designates a nozzle tube having a tapered taper made of synthetic resin. The nozzle tube 4 is detachably attached to the container 1 so as to be screwed into the screw socket portion 3 at the other end. It has been.

  The nozzle tube 4 has at least one water injection hole 5 opened on the outer peripheral surface thereof, and a portion of the outer peripheral surface of the nozzle tube 4 where the water injection hole 5 is opened has water permeability. The porous body 6 is attached so as not to fall off with, for example, an adhesive, so that the water injection hole 5 is closed with the porous body 6.

  As the water-permeable porous body 6, for example, an open-cell sponge can be used, and a woven fabric, a knitted fabric or a non-woven fabric of fibers, or a string-like body using fibers can be used.

  The irrigation apparatus having the above-described configuration is used by piercing the tapered taper nozzle tube 4 provided in the container 1 into the soil 8 in which the plant 7 is planted, as shown in FIG.

  When the nozzle tube 4 is pierced into the soil 8, the porous body 6 attached to the soil tube 8 so as to close the water injection hole 5 is in contact with the soil 8, so that the water injection hole 5 in the nozzle tube 4 is formed. It can be avoided that the soil 8 is blocked.

  Therefore, liquid such as water or liquid fertilizer is poured into the container 1 from its spout 2 or liquid is put in the container 1 in advance, so that the liquid in the container 1 is transferred to the nozzle tube 4. Since the porous body 6 penetrates through the water injection hole 5 and is poured into the soil 8, it is reliably prevented that the water injection into the soil 8 is impossible from the beginning or is interrupted in the middle of the water injection. In addition, water can be gradually poured into the soil 8 slowly.

  In this case, when the porous body 6 is made of a fiber woven fabric, knitted fabric or nonwoven fabric, or a fiber body such as a fiber string, water injection into the soil 8 is performed at a slower speed by the capillary of the fiber body. become.

  In the illustrated first embodiment, the porous body 6 is formed into a string shape, and the string-like porous body 6 is wound around the outer periphery of the nozzle tube 4 as shown in FIG. Yes.

  Further, in the second embodiment, as shown in FIG. 5, the string-like porous body 6 is inserted through the water injection hole 5 in the nozzle tube 4 so as to close it. According to this configuration, the porous body 6 can be attached to the nozzle tube 4 without moving in the axial direction.

  In particular, when the string-like porous body 6 is wound around the nozzle tube 4, the string body made of the porous body 6 is connected to two water injection holes 5 as in the third embodiment shown in FIG. Then, the nozzle tube 4 is inserted so as to pass through, and then wound around at least approximately half of the outer circumference of the nozzle tube 4, or as shown by a two-dot chain line in FIG. Later, the two ends are connected.

  Further, as in the fourth embodiment shown in FIG. 7, a concave groove 9 is provided on the outer periphery of the nozzle tube 4 and is wound around the concave groove 9 over at least a half or more, such as at least a half circumference or a full circumference. Alternatively, as in the fifth embodiment shown in FIG. 8, two protrusions 10 are provided on the outer periphery of the nozzle tube 4, and at least a half or a full periphery is provided between the protrusions 10. It can comprise so that it may wind over about half a circumference or more.

  Further, the string body made of the porous body 6 is inserted so as to penetrate through the two water injection holes 5 as in the sixth embodiment shown in FIG. 9, and then from the axial direction of the nozzle tube 4. As can be seen, the nozzle tube 4 can be mounted in a configuration in which the entire circumference of the nozzle tube 4 is wound in an 8-shape.

  With these configurations, it is possible to easily and reliably attach the porous body 6 to the outer periphery of the nozzle tube 4 so as not to drop off.

  As is clear from the description of each of the embodiments, the “winding” in each claim includes a case where the outer circumference of the nozzle tube 4 is wound over at least approximately half a circumference, and a case where winding is performed over a half circumference such as the entire circumference. Both exist.

  When the liquid in the container 1 is exhausted, the liquid is replenished so as to be poured from an upward spout 2 provided in the container 1.

  In the illustrated embodiment, the nozzle tube 4 is detachably attached to the container 1 so that the nozzle tube 4 can be replaced with a new one when the nozzle tube 4 is damaged, or its water injection hole. In addition to being able to change the irrigation speed to the soil by setting the inner diameter of 5 etc., the container 1 can be replaced with a new one when damaged, or replaced with a different internal volume. You can do it.
