Description

[Technical Field]

[0001] The present invention relates to an irrigation device. [Background technology]

[0002] BACKGROUND ART As an irrigation device used for growing plants, a known irrigation device is a type placed on the soil, which has a structure in which a water pipe is provided at the lower end of a water storage container that stores water (see, for example, Patent Document 1).

[0003] In this conventional irrigation system, a water pipe is inserted into the soil, and water is supplied from a water storage container above the soil through the water pipe into the soil by gravity.

[0004] As described above, conventional irrigation devices use gravity to supply water from a water storage container into the soil, which causes the water to flow below the plant roots in the soil, making it difficult for the plant roots to absorb the water well in the soil.

[0005] For this reason, an underground irrigation device has been devised in which a plurality of through-holes are formed in the upper part of a water storage container buried in the soil to allow plant roots to penetrate (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Utility Model Registration No. 3164251 [Patent Document 2] Utility Model Registration No. 3244888 Summary of the Invention [Problem to be solved by the invention]

[0007] However, with the above-mentioned conventional irrigation devices, it is necessary to prepare either a ground-mounted irrigation device or a ground-buried irrigation device depending on the application.In particular, with the ground-mounted irrigation device, it is not possible to adjust the amount of water sprayed, and with the ground-buried irrigation device, the water storage container that stores the water is located underground, so it is not possible to check whether water is stored in the storage container. [Means for solving the problem]

[0008] Therefore, in the present invention of claim 1, in an irrigation device, a plurality of through holes are formed in the upper part of a water storage container that stores water, a water supply device that supplies water to the water storage container and a drainage device that drains water are provided in the water storage container, a float that floats on the water is provided on the water supply device so that it can move up and down, a columnar indicator that extends up and down is provided on the upper part of the float so that it can move up and down freely along the water supply device, the upper end of the indicator protrudes higher than the upper end of the water supply device so that it is possible to visually confirm that water is stored in the water storage container, either a stop valve or a sprinkler pipe with adjustable flow rate can be connected to the drainage device, and when the stop valve is connected, the water storage container is buried in the soil and functions as an underground irrigation device that allows water to be absorbed by the roots of plants that have penetrated the through holes in the water storage container, and on the other hand, when a sprinkler pipe is connected, the water storage container is placed on the soil and functions as an above-ground irrigation device that sprinkles water from the sprinkler pipe to the soil around the plants.

[0009] In addition, in the present invention of claim 2, in the present invention of claim 1, a narrow section having a cross-sectional shape smaller than the outer shape of the float is formed inside the water supply device, and when a predetermined amount of water is stored in the water storage container, the float comes into close contact with the narrow section, preventing the water stored in the water storage container from evaporating from the water supply device.

[0010] Furthermore, in the present invention according to claim 3, in the present invention according to claim 1 or claim 2, multiple water storage containers are connected to the water supply device in a horizontal arrangement, so that water can be stored in multiple water storage containers from the water supply device. [Effects of the Invention]

[0011] The present invention provides the following effects.

[0012] That is, in the present invention, in an irrigation device, a plurality of through holes are formed in the upper part of a water storage container that stores water, a water supply device that supplies water and a drainage device that drains water are provided in the water storage container, a float that floats on the water is provided on the water supply device so that it can move up and down, a columnar indicator that extends up and down is provided on the top of the float so that it can move up and down along the water supply device, the upper end of the indicator protrudes above the upper end of the water supply device, and it is possible to visually confirm that water is stored in the water storage container by checking the indicator, and either a stop valve or a sprinkler pipe with adjustable flow rate can be connected to the drainage device, and when the stop valve is connected In this system, the water storage container is buried in the soil, and functions as a buried irrigation device that allows water to be absorbed by the roots of plants that have penetrated the through holes in the water storage container.On the other hand, when a sprinkler pipe is connected, the water storage container is placed on top of the soil, and functions as an above-ground irrigation device that sprinkles water from the sprinkler pipe onto the soil around the plants.Therefore, one irrigation device can be used as both a buried irrigation device and an above-ground irrigation device, and it is easy to confirm that water is stored in the water storage container, making the irrigation device easy to use.

[0013] In particular, if a narrow section with a cross-sectional shape smaller than the outer shape of the float is formed inside the water supply device, and when a predetermined amount of water is stored in the water storage container, the float comes into close contact with the narrow section, preventing the water stored in the water storage container from evaporating from the water supply device, it is possible to prevent water from evaporating from the water supply device that connects from the soil to above, and to maintain the amount of water in the water storage container.

[0014] Furthermore, if a plurality of water storage containers are connected to the water supply device in a horizontal line so that water can be stored in the plurality of water storage containers from the water supply device, plants can be grown evenly over a wide area.

[0016] Hereinafter, a specific configuration of the irrigation device according to the present invention will be described with reference to the drawings.

[0017] As shown in Figure 1, the irrigation device 1 can function as an underground irrigation device (Figure 1(a)) used to allow the roots of plants to absorb water 4 in the soil 3 of a planter 2, etc., when growing plants, and can also function as an above-ground irrigation device (Figure 1(b)) used to sprinkle water 4 on the soil 3.

[0018] As shown in Figures 1 to 3, this irrigation device 1 is buried in soil 3 or placed on top of the soil 3, and has a generally horizontal water storage container 5 for storing water 4, a generally vertical water supply device 6A for supplying water 4 to the water storage container 5 from above the soil 3, and a generally vertical drainage device 6B for draining the water 4 from the water storage container 5. Here, the front end of the water storage container 5 is detachably connected to the lower rear sides of the water supply device 6A and the drainage device 6B.

[0019] The water storage container 5 has a hollow cylindrical container body 7 extending horizontally in the front-to-rear direction, and a closure lid 8 removably attached to the rear end opening of the container body 7, and a connecting lid 9 removably attached to the front end opening of the container body 7.

[0020] The container body 7 has a plurality of through-holes 10 formed at the top, penetrating from the inside to the outside. These through-holes 10 are holes through which plant roots grow and penetrate into the soil 3 in a buried-type irrigation device, and are also holes through which rainwater penetrates in a placed-on-the-ground irrigation device, and the surface is covered with a flexible net 11 to prevent the intrusion of the soil 3, dust, etc.

[0021] The blocking lid 8 can be removed from the container body 7 to allow the soil 3, water 4, dust, etc. inside the container body 7 to be discharged.

[0022] The connecting lid 9 has a water supply port 12 formed in the center thereof, which passes horizontally from inside to outside, and the water supply tool 6A is removably connected to the water supply port 12.

[0023] The water supply device 6A has a funnel 13, a water supply pipe 14, and a connecting pipe 15, and a water volume measuring device 16 is provided in the hollow space formed inside these components.

[0024] The funnel 13 has open upper and lower ends, its diameter gradually decreasing from top to bottom, and its lower end is detachably attached to the upper end of the connecting pipe 15 via a joint 17. The joint 17 is made of an elastic body, and has a cylindrical portion at one end (lower) that is press-fitted into the connecting pipe 15, and a tapered portion at the other end (upper) that is press-fitted into the lower end opening of the funnel 13.

[0025] The water supply pipe 14 is connected to the base end (front end) of a connecting pipe 19 extending horizontally in the front-to-back direction at the middle part of the upper hollow pipe 18A extending vertically in the up-down direction, and the water supply port 12 of the water storage container 5 is attached to the tip end (rear end) of the connecting pipe 19 in a manner that allows it to be freely attached and detached.

[0026] Furthermore, the lower end of connecting pipe 15 of water supply pipe 14 is attached to the upper opening of upper hollow pipe 18A. Here, the inner diameter of upper hollow pipe 18A and the outer diameter of connecting pipe 15 are made the same, and the inner diameter of connecting pipe 15 is made smaller than the inner diameter of upper hollow pipe 18A. This forms narrow section 21 inside water supply device 6A, where the horizontal cross-sectional shape (cross-sectional area) of connecting pipe 15 becomes smaller in a stepwise (discontinuous) manner from bottom to top than the horizontal cross-sectional shape (cross-sectional area) of upper hollow pipe 18A.

[0027] The connecting pipe 15 extends vertically in the up-down direction, allowing the water 4 supplied from the upper funnel 13 to flow into the water supply pipe 14. This allows the water supply device 6A to supply water from above the soil 3 to the water storage container 5 inside the soil 3 when used as an underground irrigation device.

[0028] The water level measuring device 16 is used to visually check the approximate amount of water 4 inside the water storage container 5 from the outside (above the soil 3), and has an indicator 23 attached to the upper end of a float 22 that extends up and down.

[0029] The float 22 is housed inside the upper hollow tube 18A and is formed hollow so that it floats on the water 4. This allows the water volume measuring device 16 to have the float 22 float up and down following the top surface of the water 4 inside the water storage container 5 (upper hollow tube 18A of the water supply device 6A).

[0030] The indicator 23 is formed in the shape of a column extending vertically in the up-down direction, and has a visible mark 24 formed on the top. This allows the water volume measuring instrument 16 to visually check the mark 24 of the indicator 23 from above the soil 3, thereby making it possible to confirm the presence or absence and approximate amount of water 4 inside the water storage container 5 in the soil 3.

[0031] That is, as shown in Figure 4(a), when the amount of water 4 inside the water storage container 5 decreases, the float 22 and the indicator 23 drop accordingly, and the position of the mark 24 can be visually confirmed.

[0032] As shown in Figure 4(b), when water 4 is supplied into the water storage container 5, the float 22 and indicator 23 of the water volume measuring device 16 rise accordingly, and the position of the mark 24 can be confirmed by visual inspection. Furthermore, when a predetermined amount of water 4 is supplied into the water storage container 5 and a limiting condition is reached where any more water 4 is supplied and the water overflows from the through-hole 10, the position of the mark 24 coincides with the upper end of the funnel 13, and the position of the mark 24 can be confirmed by visual inspection. Furthermore, in this limiting condition, the float 22 comes into close contact (abuts) with the narrow portion 21 inside the water supply device 6A, blocking the narrow portion 21 with the float 22, and preventing the water 4 inside the water storage container 5 from evaporating from the water supply device 6A.

[0033] Drainage tool 6B is capable of selectively and detachably connecting either stop valve 20A or sprinkler pipe 20B to the lower end opening of lower hollow pipe 18B, which extends vertically in the up-down direction and communicates with water supply pipe 14. By removing stop valve 20A or sprinkler pipe 20B, water volume measuring device 16 can be inserted removably into water supply tool 6A, and soil 3, water 4, dust, etc. from inside water storage container 5 can be drained.

[0034] Sprinkler pipe 20B has a flexible hollow pipe 20D with its base end inserted through joint 20C, which is detachably attached to the bottom opening of lower hollow pipe 18B, and bolts 20E and 20F for adjusting the flow rate are threaded into the base and tip of hollow pipe 20D. Sprinkler pipe 20B allows the amount of water discharged from hollow pipe 20D to be adjusted by adjusting the degree to which bolts 20E and 20F are screwed in. Joint 20C has a similar structure to joint 17.

[0035] The irrigation device 1 is configured as described above, and when a stop valve 20A is connected to the lower hollow pipe 18B of the drainage device 6B, it functions as an irrigation device buried in the ground, and when a sprinkler pipe 20B is connected to the lower hollow pipe 18B of the drainage device 6B, it functions as an irrigation device placed on the ground.

[0036] In the buried irrigation device, when water 4 is poured into the water storage container 5 buried in the soil 3 through the funnel 13 of the water supply device 6A above the soil 3, the water can be stored in the water storage container 5 buried in the soil 3 via the connecting pipe 15 and the water supply pipe 14, and the roots of the plants grow and penetrate into the water storage container 5 through the through-holes 10, allowing the plant roots to absorb the water 4 from the water storage container 5. Moreover, the irrigation device 1 makes it easy to confirm from above the soil 3 using the water volume meter 16 that water 4 is being stored in the water storage container 5 buried in the soil 3.

[0037] On the other hand, in the above-ground irrigation device, water 4 supplied from the funnel 13 of the water supply device 6A or rainwater can be stored in the water storage container 5, and water can be sprayed from the sprinkler pipe 20B placed on the soil 3.

[0038] In the above-mentioned irrigation device 1, a connecting lid 9 with a water supply port 12 is provided at the front end of the container body 7 of the water storage container 5, and a connecting pipe 19 is provided in the middle of the water supply pipe 14 of the water supply device 6A, and a single water storage container 5 extending horizontally in the front-to-back direction is connected to the rear of the water supply device 6A, but this structure is not limited to this.

[0039] For example, in the irrigation device 25 shown in Figure 5, the front end of the container body 27 of the water storage container 26 is closed with a closing lid 28, and the lower end of the connecting pipe 15 of the water supply device 30A is inserted into a through-hole 29 formed in the upper front part of the container body 27, penetrating vertically, and the upper end of the hollow pipe 32 of the drainage device 30B is inserted into a through-hole 31 formed in the lower front part of the container body 27, penetrating vertically and coinciding with the through-hole 29. In this case, the lower end of the connecting pipe 15 forms a narrow portion 33 having a cross-sectional shape smaller than the outer shape of the float 22, and when a predetermined amount of water is stored in the water storage container 26, the float 22 comes into close contact with the narrow portion 33, preventing the water stored in the water storage container 26 from evaporating from the water supply device 30A. Note that in the irrigation device 25, the stop valve 20A is connected to the drainage device 30B, but a sprinkler pipe 20B can also be connected to the drainage device 30B.

[0040] In addition, in the irrigation device 34 shown in Figure 6, an L-shaped branch pipe 37 extending horizontally in the left-right direction is connected to the hollow pipe 36 of the water supply device 35A, and two identical water storage containers 38, 38 are connected to the water supply device 35A in a horizontal arrangement. In this way, multiple water storage containers 38, 38 may be connected to the water supply device 35A in a horizontal arrangement at the same height. In particular, when multiple identical water storage containers 38, 38 are connected in a horizontal arrangement at the same height, water 4 can be supplied evenly to plant roots over a wider area for growth. In the irrigation device 34, the stop valve 20A is connected to the drainage device 35B, but a sprinkler pipe 20B can also be connected to the drainage device 35B.

[0041] 7, the irrigation device 39 may have a structure in which the container body 41 of the water-storage container 40 extends vertically, an upper lid 43 having a plurality of through-holes 42 extending vertically is removably attached to the upper opening of the container body 41, and a lower lid 44 is removably attached to the lower opening of the container body 41, and a water inlet 45 is formed in the lower front part of the container body 41 and is connected to a connecting pipe 47 of a water supply device 46A. In this case, the positions of the plurality of through-holes 42 through which the roots of the plants penetrate can be aligned horizontally, allowing the water 4 to be evenly supplied to the roots of the plants. In the irrigation device 39, the stop valve 20A is connected to the drainage device 46B, but a sprinkler pipe 20B can also be connected to the drainage device 46B.

[0042] As explained above, the irrigation devices 1, 25, 34, 39 have a plurality of through holes 10, 42 formed in the upper part of the water storage container 5, 26, 38, 40 that stores the water 4, and are provided with the water supply device 6A, 30A, 35A, 46A that supplies the water 4 and the drainage device 6B, 30B, 35B, 46B that drains the water 4 in the water storage container 5, 26, 38, 40, and are provided with a float 22 that floats on the water 4 and is movable up and down in the water supply device 6A, 30A, 35A, 46A, and a columnar indicator 23 that extends up and down is provided on the upper part of the float 22 so that it can rise and fall freely along the water supply device 6A, 30A, 35A, 46A, and the upper end of the indicator 23 protrudes above the upper end of the water supply device 6A, 30A, 35A, 46A, and the indicator 23 is used as an object. By visually inspecting the water storage containers 5, 26, 38, 40, it is possible to confirm that water 4 is stored in the water storage containers 5, 26, 38, 40, and either a stop valve 20A or a flow-rate-adjustable sprinkler pipe 20B can be connected to the drainage devices 6B, 30B, 35B, 46B. When the stop valve 20A is connected, the water storage containers 5, 26, 38, 40 are buried in the soil 3, and function as a buried-in-soil irrigation device that allows the roots of plants that have penetrated the through-holes 10, 42 of the water storage containers 5, 26, 38, 40 to absorb the water 4. On the other hand, when the sprinkler pipe 20B is connected, the water storage containers 5, 26, 38, 40 are placed on the soil 3, and function as an above-soil irrigation device that sprinkles water 4 from the sprinkler pipe 20B onto the soil 3 around the plants.

[0043] Therefore, with the irrigation devices 1, 25, 34, 39 configured as described above, a single irrigation device 1, 25, 34, 39 can be used as either an underground irrigation device or an above-ground irrigation device, and it is easy to confirm that water 4 is stored in the water storage container 5, 26, 38, 40, making the irrigation devices 1, 25, 34, 39 easy to use.

[0044] In addition, the above-mentioned irrigation devices 1, 25, 34, 39 form narrow sections 21, 33 with a cross-sectional shape smaller than the outer shape of the float 22 inside the water supply devices 6A, 30A, 35A, 46A, and when a predetermined amount of water 4 is stored in the water storage container 5, 26, 38, 40, the float 22 comes into close contact with the narrow sections 21, 33, so that the water 4 stored in the water storage container 5, 26, 38, 40 does not evaporate from the water supply devices 6A, 30A, 35A, 46A.

[0045] Therefore, the irrigation devices 1, 25, 34, 39 configured as described above can prevent water 4 from evaporating from the water supply devices 6A, 30A, 35A, 46A connected from within the soil 3 and above the soil 3, and can maintain the water level in the water storage containers 5, 26, 38, 40.

[0046] The irrigation device 34 is configured such that a plurality of water storage containers 38 are connected to the water supply tool 35A in a horizontal arrangement, so that the water 4 can be stored in the plurality of water storage containers 38.

[0047] Therefore, the irrigation device 34 can grow plants evenly over a wide area. [Explanation of symbols]
