BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an irrigation device, and more particularly to an irrigation device for supplying water or liquid fertilizer into a ridge provided with a mulch film for keeping soil warm and preventing weeds.

[0002]

2. Description of the Related Art Conventionally, as a method of irrigating a ridge when a mulch film is used, a worker irrigates the holes of the mulch film in which seedlings of a crop are planted, one by one. , Water does not immediately penetrate into the ridge soil. For this reason,
In order to perform sufficient irrigation, water is irrigated several times while waiting for water to penetrate into the soil. There is also a method of directly irrigating from the river to the ridge, and this method can complete the irrigation work in a short time.

[0003]

However, the above conventional irrigation methods have the following problems. In order to sufficiently irrigate the roots of seedlings planted in the mulch film holes one by one, irrigate a small amount of water several times while waiting for water to penetrate into the soil. Since it is necessary, the irrigation work efficiency is poor and it takes too much time and effort. Further, if water is directly irrigated from the river to the furrows, there is a problem that for a while, people cannot enter the furrows, the weeds grow thick, and the crop becomes overhumid and the crops are likely to be damaged. Therefore, the present invention has been made to solve the above problems, and an object thereof is to provide an irrigation tool capable of supplying a sufficient amount of water or liquid fertilizer into a ridge in a short irrigation time.

[0004]

In order to solve the above problems, the present invention has the following constitution. That is, in the irrigation tool that supplies water into the ridge where the mulch film is laid in order to keep the soil warm and prevent weeds, etc., has a vessel body and a tubular outer shape, and is directed downward from the bottom of the vessel body. It is characterized in that it is provided with an extraction pipe which is extended and has a through hole provided on the outer wall surface for communicating the inner space of the body with the outside. Further, the container body may be formed of an outer tubular portion, an inner tubular portion, and a bottom portion provided to form the internal space between the outer tubular portion and the inner tubular portion. Further, the through hole is formed by cutting a part of the outer wall surface of the extraction pipe obliquely from above the outer wall surface toward the lower side, and from the position of the outer wall surface corresponding to the tip end portion of the cut, the center of the extraction pipe is formed. It is more preferable to form a notch in a direction substantially perpendicular to the axis of the drawing pipe and remove it, and even if the opening edge portion of the drawing pipe on the bottom surface is formed to project into the internal space of the container body. good.

[0005]

According to the present invention, if the watering tool is installed on the ridge by inserting the extraction pipe into the ridge from above the mulch film, and water is supplied into the internal space of the container, Is reliably supplied into the ridge from the through hole provided on the outer wall surface of the extraction pipe via the extraction pipe. Further, when the body is formed of the outer cylinder portion, the inner cylinder portion, and the bottom portion provided to form the internal space between the outer cylinder portion and the inner cylinder portion, the inner cylinder portion forms a multi-film hole. The irrigation equipment can be installed so as to match, and reliable irrigation can be performed near the capillary roots of the seedlings planted in the holes.
In addition, the through hole is formed by obliquely cutting a part of the outer wall surface of the drawing pipe from the upper side of the outer wall surface toward the lower side, and from the position of the outer wall surface corresponding to the tip end portion of the cutting toward the center of the drawing pipe. If the notch is inserted at a right angle to the axis of the drawing pipe and removed to form, the drawing pipe inserted in the ridge will be difficult to pull out, and the opening edge part of the drawing pipe on the bottom will be placed in the inner space of the vessel. If it is formed so as to project, it is possible to prevent sand or the like that has entered the body from entering the drawing pipe.

FIG. 7 is a front cross-sectional view showing an embodiment of the opening edge portion of the extraction pipe provided on the bottom surface of the watering implement of FIGS. 1 and 5. FIG. 8 is a front sectional view showing another embodiment of the opening edge portion of the extraction pipe on the bottom surface of the watering implement.

First, the first embodiment will be described with reference to FIGS. 1 and 4 is a ridge, and a synthetic resin mulch film 12 is laid on the surface of the ridge 10 in order to keep the soil in the ridge 10 warm and to prevent overgrowth of weeds. Further, 14 is a hole provided at a predetermined interval in the mulch film 12, and the seedlings 16 of the crop are planted in the soil of the ridge 10 through the holes 14. A seed may be planted instead of the seedling 16.

First, the structure of the watering implement 18 will be described with reference to FIG. Reference numeral 20 denotes a container, which is formed, for example, in the shape of a rectangular parallelepiped box whose upper surface is open. The shape of the container 20 may be various shapes such as a rectangular tube shape such as a triangle, a cylindrical shape, an elliptic tube shape, etc., instead of a rectangular parallelepiped having an open upper surface. Reference numeral 22 is a drawing pipe having a tubular outer shape and extending downward from the bottom portion 24 of the container 20. Further, the leading end of the extraction pipe 22 is closed, and the inner space 26 of the container 20 is provided on the outer wall surface.
A through hole 28 that communicates with the outside is provided. Through hole 2
The shape of 8 may be various shapes such as a circular shape, an elliptical shape, a slit shape, a polygonal shape, and a mesh shape in consideration of the amount of water supplied into the soil and the strength of the extraction pipe 22. The container 20 and the extraction pipe 22 are integrally formed using a synthetic resin, particularly a vinyl chloride-based synthetic resin that is not easily deteriorated by sunlight. It should be noted that the number of the extraction tubes 22 may be one instead of two in this embodiment, or three or more may be provided. Further, the tip end portion of the extraction pipe 22 is usually formed to be sharp as shown in FIG. 2 so as to easily pierce the mulch film 12 or the ridges 10, but it may be flat or spherical.

Next, the method of using the watering implement 18 will be described with reference to FIG.
Will be explained. First, place the watering device 18 between the holes 14 of the mulch film 12 in which the seedlings 16 are planted.
The tips of the extraction pipes 22 are inserted into the ridges 10 one by one so as to penetrate the mulch film 12 and penetrate into the soil of the ridges 10. The insertion is continued until the bottom surface of the watering implement 18 comes into contact with the top surface of the mulch film 12. Since the through hole 28 provided in the extraction pipe 22 is provided on the outer wall surface of the extraction pipe 22 and opens in the direction orthogonal to the inserting direction (the axial direction of the extracting pipe 22), the soil through hole 28 is inserted during the inserting work. It is possible to prevent the penetration hole 28 from being clogged and the through hole 28 is clogged. In addition, a through hole may be provided in the closed leading end of the extraction pipe 22 as long as the soil particles are hard to enter. Further, the number of the watering implements 18 arranged between the holes 14 of the multi-film 12 may be provided as needed, such as a few or two, and is not limited to one.

When the installation of the watering implement 18 is completed, the container 20
Pour water into the interior space 26 of the. The water in the container body 20 passes through the extraction pipe 22 through the through hole 28 as shown by the arrow, and the ridge 1
It penetrates into the soil of No. 0 and is surely supplied to the capillary root of the seedling 16 planted in each hole 14 of the mulch film 12. Also,
By using a liquid fertilizer (for example, a fertilizer dissolved in water) instead of water, fertilization can be applied to the ridges.
In particular, in fertilizer application, which requires a high product cost of fertilizer, since it can be reliably supplied directly to the capillary roots of the seedlings 16, it is possible to improve the effect with a small amount, and therefore the cost for fertilizer application can be reduced. Further, since the extraction pipe 22 penetrates the mulch film 12 and penetrates into the soil of the ridge 10, the watering device 18 will not be blown off by wind even when water is not contained in the vessel 20. Further, as shown in FIG. 3, the through hole 28 is formed by cutting a part of the outer wall surface of the extraction pipe 22 obliquely from the upper side to the lower side of the outer wall surface of the outer wall surface corresponding to the tip portion of the cut. A notch may be formed by removing a notch from the position toward the center of the drawing pipe 22 at a substantially right angle to the axis of the drawing pipe 22.
When the through hole 28 has this shape, even if an upward force is applied to the extraction pipe 22 inserted into the ridge 10, the opening lower end edge of the through hole 28 that is substantially perpendicular to the axis of the extraction pipe 22 contacts the soil. It is preferable because it is in contact with each other and it is difficult to come out.

Next, a second embodiment will be described with reference to FIGS. First, the configuration of the watering implement 30 will be described. The same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. The body 32 includes a cylindrical outer cylinder part 34 and a cylindrical inner cylinder part 3 arranged inside the outer cylinder part 34.
6 and a ring-shaped bottom portion 24 provided to form the internal space 26 between the outer tubular portion 34 and the inner tubular portion 36. In the present embodiment, both the outer tubular portion 34 and the inner tubular portion 36 are formed in a cylindrical shape, but either one or both may be formed in a rectangular tubular shape (the cross-sectional shape is triangular, quadrangular, or polygonal). The extraction pipe 22 extends downward from the bottom portion 24 of the container 32.

Next, the method of using the irrigation tool 30 is shown in FIG.
Will be explained. The description of the same parts as those in the first embodiment will be omitted. First, the irrigation implements 30 are arranged one by one at the positions of the holes 14 of the mulch film 12 in which the seedlings 16 are planted so that the inner tube portions 36 of the irrigation implement 30 are aligned. As a result, the seedling 16 is located inside the inner tubular portion 36 of the irrigation tool 30 and grows in this state. In addition, when the positions of the holes 14 of the multi-film 12 are close to each other and one irrigation tool 30 cannot be provided for each hole 14, even if the irrigation tools 30 are arranged every other hole, they are adjacent to each other. Since the holes 14 are close to each other, sufficient water can be supplied to the seedlings 16 in the holes 14 where the watering implement 30 is not provided. Further, the extraction pipe 22 is provided at regular intervals over the entire circumference of the ring-shaped bottom portion 24.
By providing the water, water can be supplied from the entire periphery of the capillary root of the seedling 16, and more reliable water supply can be realized.

Further, the bottom surface 2 of the above-described irrigation equipment 18, 30.
The opening edge portion of the extraction pipe 22 of No. 4 is formed so as to project into the vessel body internal space 26 and is slightly higher than the other bottom surface (specifically, as shown in FIG. 7, the opening edge of the extraction pipe 22 of the bottom surface 24). A tubular wall portion 38 extending upward is provided in the portion, or the bottom surface 24 of the opening edge portion of the extraction pipe 22 is raised as shown in FIG. 8) and inside the bodies 20, 32 by wind or the like. It is possible to prevent the sand 40 and the like that have entered from entering the extraction pipe 22,
Since the clogging of the drawing pipe can be reduced, the irrigation work into the ridge 10 can be efficiently performed.

Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and many modifications can be made without departing from the spirit of the invention. Of course.
