Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an irrigation system.

[0002]

2. Description of the Related Art Conventionally, there has been proposed an irrigation system capable of automatically supplying water to plants vegetated in a container (pot).

This conventional example is configured so that water can be automatically supplied to a plant by using an appropriate power source, and a time suitable for watering the plant, for example, a predetermined time in the morning and evening. By setting the timer on, a predetermined amount of water can be supplied at the time desired by the user.

However, the applicant of the present invention has tried variously with respect to this conventional example, and has confirmed the following problems.

That is, the rate at which the soil in the pot dries varies depending on various conditions such as the type of plant, the nature of the soil in the pot, and the surrounding environment (natural environment such as temperature and humidity), so it is more than expected. If the water in the pot dries quickly or the water supply becomes insufficient, the plants may die.

However, if the time interval for supplying water is shortened or the amount of water supplied is increased more than necessary, the roots will be in a state of being immersed in water, causing root rot. However, the current situation is that we have not been able to respond sufficiently.

The present invention provides an irrigation system which solves the above problems.

The present invention relates to an irrigation system characterized in that the water in the supply path 5 is pumped and supplied .

Further, in the irrigation device for supplying water to the plants 2 arranged in the container 1, an appropriate position of the container mounting portion 8 on which the container 1 in which the plants 2 are arranged is mounted is set as a fulcrum P. The container mounting portion 8 is tiltably provided, and the container 1 on which the plant 2 and the soil 23 are arranged is provided with a weight 7 having a weight that is balanced with the total weight when a predetermined amount of water is irrigated. It is characterized in that a water supply means 4 is provided which is connected to the container mounting portion 8 and supplies the reduced amount of water to the container 1 when the water in the container 1 is reduced. It relates to a watering device.

Further, in the irrigation system according to claim 2 ,
As the water supply means 4, pressure water is provided in the water supply passage 5, and the valve portion 6 in the water supply passage 5 is opened and closed by the tilting of the container mounting portion 8 to supply and supply water into the container 1. The present invention relates to an irrigation device, which is configured to be stopped.

[0012]

The present invention intends to determine the amount of water supplied based on the amount of water in the container 1, which is completely different from the idea of the conventional example.

For example, the water content in the container 1 in which the plant 2 is arranged is detected by the water content confirmation means 3, and if the water content is insufficient (for example, if the weight of the water content is less than a predetermined value), water is added to compensate for it. Water is supplied to the plant 2 by the supply means 4.

At this time, when the water content in the container 1 returns to a predetermined value, the water supply means 4 stops the water supply.

Therefore, according to the present invention, since the water content in the container 1 itself determines whether or not to supply water, the plant 2 is always watered without being affected by various conditions. It will be an epoch-making irrigation system with extremely high commercial value as it will be able to supply the required amount of water at a good timing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings illustrate one embodiment of the present invention and will be described below.

Reference numeral 1 is a pot as a container in which the plant 2 is vegetated.

The present embodiment is an irrigation system for supplying water to a plant 2 arranged in a container 1, and a moisture confirmation means 3 for confirming an increase or decrease in water in the container 1 in which the plant 2 is arranged. The water supply means 4 for supplying water to the plant 2 is provided in association with the water content confirmation means 3.

Below, a detailed explanation will be given of each component of the present embodiment.

The water supply means 4 is constructed by providing a valve portion 6 in a part of the water supply passage 5 through which water is pumped.

As shown in FIGS. 1 and 2, the water supply passage 5 is a water passage made up of a first pipe member 5a and a second pipe member 5b made of synthetic resin having appropriate flexibility. The second pipe member 5b located on the downstream side of 5 has a tip end portion bent and formed in a tapered shape to form a water supply portion.

Further, the water supply path 5 is provided with a water pumping section 9 on the upstream side thereof.

The water pumping unit 9 is composed of a water storage bag body 10 having a predetermined capacity for storing water and a water introducing body 11 connected to the water storage bag body 10.

The water storage bag body 10 is made of a synthetic resin (rubber) member having an appropriate degree of flexibility to restore the original shape when it swells as shown in FIGS. The water storage bag body 10 is connected to the water introducing body 11 through the hose 12 in a water-permeable state.

The water introducing body 11 is a cylindrical body formed with an appropriate synthetic resin member, and the water introducing body 11 is connected through a hose 13 to a water source (water supply) (not shown) in a water-flowing state. Further, the water introducing body 11 is the first pipe member 5a related to the water supply passage 5.
Is connected with water flow.

A water flow switching valve (not shown) is provided inside the water introducing body 11.

This water flow switching valve is constructed so that it can be switched by rotating a knob 11a provided on the upper portion of the water introducing body 11, and the water pumped from the water source is stored in the water storage bag body 10. Can be switched to a state in which water can be circulated to the first tube member 5a (a state in which water pumped from a water source is stopped and the water bag 10 is compressed to allow water to circulate to the first pipe member 5a).

Therefore, the water pumping unit 9 pumps the tap water into the water bag 10 by passing it through the water introducing body 11 to fill the water bag 10, and then switches the water switching valve to switch the water bag body.
The water is discharged due to the restoring force (contracting force) of returning to the original position of 10, and the discharged water flows through the water introducing body 11 to the first pipe member 5a related to the water supply passage 5. In this state, the water in the water supply passage 5 is always under pressure due to the compression of the water storage bag 10.

A valve portion 6 is provided in the water supply path 5 (between the first pipe member 5a and the second pipe member 5b).

The valve portion 6 is composed of an L-shaped tubular body 14 having a valve structure inside, and the L-shaped tubular body 14 has a shaft 24 as a fulcrum at a predetermined position of the base body a according to this embodiment. It is pivotally attached to.

The L-shaped tubular body 14 is formed by forming a suitable synthetic resin member as shown in FIGS. 1 to 4, and is connected to the horizontal tubular portion 14a and the horizontal tubular portion 14a in an orthogonal state. Vertical cylinder part 14
and b.

The horizontal cylinder portion 14a and the vertical cylinder portion 14b constituting the L-shaped cylinder body 14 are provided with a first opening / closing valve 15 and a second opening / closing valve 16, respectively.

The first on-off valve 15 is pivotally mounted at the base end side opening portion of the horizontal tubular portion 14a so as to be slidable, and at a position where it abuts on the stopper 18 in the right direction in FIGS. It is configured to swing up to. Normally, this first on-off valve 15
Is held in the closed state by being pushed leftward in FIGS. 3 and 4 by the water pumped from the water pumping unit 9.

Further, the horizontal cylindrical portion 14a is provided therein with three spheres 17a having a large diameter and one sphere 17b having a small diameter.

The spherical bodies 17a and 17b press the first on-off valve 15 when the L-shaped cylindrical body 14 is tilted from the substantially horizontal state (a state in which it is slightly inclined to the left side in FIG. 3) to the state in FIG. The water is sent from the water pressure feeding unit 9 through the L-shaped cylinder 14 at this time, and when the L-shaped cylinder 14 is returned to the horizontal state thereafter. The pressing of the spheres 17a and 17b on the first on-off valve 15 is released, and at this time, the first on-off valve 15 is closed again by the water pressure-fed from the water pressure feeding section 9.

The second on-off valve 16 is pivotally mounted on the upper end side opening portion of the vertical cylindrical portion 14b at its base end so as to be freely slidable, and is constructed so as to be slidable upward in FIGS. There is.

This second on-off valve 16 is the above-mentioned first on-off valve.
When the valve 15 is opened, it is pressed by the water flowing in the L-shaped tubular body 14 and oscillates upward (downward in FIGS. 3 and 4) to be in an open state, while the flowing water from the first opening / closing valve 15 is stopped. , Is pressed by water in the second pipe member 5b of the water supply passage 5 and is slid downward (downward in FIGS. 3 and 4) to be in a closed state. still,
Reference numeral 19 is a sphere that holds the closed state of the second on-off valve 16.

Further, a container mounting portion 8 is provided above the base body a.

The container mounting portion 8 is a dish-shaped body made of an appropriate synthetic resin as shown in FIGS. 1 and 2, and a projection 8a vertically provided on the back surface thereof is provided at a predetermined position of the base body a. Support part 20
It is pivotally attached to and can be tilted.

An arm rod 21 is projected from the projection 8a of the container mounting portion 8, and a weight 7 is suspended from the tip of the arm rod 21.

The weight 7 is for holding the container mounting portion 8 on which the bowl 1 is mounted in a horizontal state (state in FIG. 1).

Specifically, the weight 7 is used when the pot 1 in which the plant 2 is planted is placed on the container placing portion 8 and the soil 23 in the pot 1 is supplied with water having an optimum water content. The weight 7 has a weight (equal weight) that can be balanced with the total weight. Therefore, the weight 7 causes the container mounting portion 8 to be in a horizontal state at a delicate position such that it floats or does not float from the support 23. In this state, when the plant 2 absorbs water or evaporates water from this state and becomes lighter, the weight 7 wins (the weight balance is lost) and the container mounting portion 8 tilts. Is configured.

The container mounting portion 8 has a connecting rod on its side surface.
22 is provided vertically, and the lower end of the connecting rod 22 is connected to the L-shaped tubular body 14 related to the valve portion 6. When the container mounting portion 8 is horizontal, the L-shaped tubular body 14 is also horizontal, When the mounting portion 8 tilts, the L-shaped tubular body 14 also tilts and is in a tilted state.

Therefore, when the container mounting portion 8 is in a horizontal state (when the water content in the bowl 1 is sufficient), the first opening / closing valve 15 of the L-shaped cylinder 14 is closed, and the container mounting portion 8 is closed. When the 8 tilts (when the water content decreases), the L-shaped tubular body 14 also tilts and becomes a sphere.
17a and 17b roll, and the first on-off valve 15 is opened.

Reference numeral 8b is a drain hole.

A method of using the irrigation device having the above configuration will be described.

First, the water is pumped from the water source to store the water in the water storage bag body 10, and in this state, the water switching valve of the water introducing body 11 is switched to complete the setting of the water supply means 4 ( At this time, the water supply bag 5 and the L-shaped tubular body 14 (valve portion 6) as well as the water storage bag body 10 are filled with water.

On the other hand, the bowl 1 in a state where the soil is sufficiently moistened is placed on the container mounting portion 8 and the weight 7 is adjusted so that the container mounting portion 8 becomes horizontal. Set.

In this state, if the water in the bowl 1 is insufficient,
The weight 7 wins and the container mounting portion 8 tilts, and the L-shaped tubular body 6 also tilts with the tilting of the container mounting portion 8, so that the first opening / closing valve 15 in the L-shaped tubular body 15 and The second on-off valve 16 opens and the water pumped from the water storage bag body 10 passes through, so that the water is supplied from the second pipe member 5b of the water supply path 5 into the bowl 1.

After that, when the bowl 1 regains a predetermined weight, the container mounting portion 8 is returned to the horizontal state, and when the container mounting portion 8 is in the horizontal state, the first opening / closing in the valve portion 6 is performed. The valve 15 and the second on-off valve 16 are closed, the flow of water is stopped, and the supply of water to the bowl 1 is stopped.

Thereafter, every time the water in the bowl 1 is dried, this operation is repeated as long as there is water in the water storage bag body 10.

Since the present embodiment is constructed as described above, since it is a construction for determining whether or not to supply water based on the weight of water in the container 1, the plant 2 is always affected by various conditions.
The necessary amount of water can be satisfactorily supplied at a good timing to give water to the.

An appropriate sensor is adopted as the water content confirmation means 3, and the reduced water content (water content) is calculated based on the data from the sensor using an appropriate microcomputer or the like, and the calculated water content is calculated. It is also possible to supply in the container 1.
