The present invention relates to a simple assembling type automatic watering apparatus capable of performing the following.

[0002]

[Prior art]

 Conventionally, when cultivating plants in horticultural facilities such as home flower beds, it is important to supply the appropriate amount of water to the plants in a timely manner. However, manual work using a water supply container requires more labor as the watering area becomes larger. Recently, automation of watering has been attempted even in flower beds in homes. For example, a sprinkler that sprays water in a fountain shape upward from the ground is used.

[0003]

[Problems to be solved by the invention]

 However, it is difficult for such a watering device of the type that blows up from below to scatter water to a high position when watering the leaves of tall plants. In addition, when the number of flowerbeds is increased, there is a problem that the watering area cannot be easily expanded and the watering area is narrow and limited.

[0004] On the other hand, there is a method in which a supporting member is erected on the ground and a watering pipe is horizontally laid over the supporting member to spray water from above the plants. However, in the conventional structure of this kind, since one watering pipe is integrally connected to the support member, assembling and disassembling operations are troublesome. In addition, a high-output pump and a high-pressure-resistant water supply pipe are required between the water supply source and the sprinkling pipe, and the entire apparatus becomes complicated and large-scale. The present invention has been made in view of the above-mentioned problem, and has as its object the purpose of being able to spray water on a leaf branch of a plant at a high position without a pump and to easily respond to changes in expansion and contraction of a watering area. It is to provide a sprinkler.

[0005]

[Means for Solving the Problems]

 For this reason, in the present invention, a sprinkling pipe having a plurality of water holes is detachably mounted between a plurality of supporting members erected on the ground, and a water supply hose communicating with a water tap is connected to the sprinkling pipe. The sprinkling pipes are connected to each other, and a fixing fitting for fixing a joint end of the sprinkling pipes is detachably mounted on an upper portion of the supporting member.

In the present invention, it is possible to provide a plurality of rows of support members around which water sprinkling pipes are provided, and to provide a plurality of open / close cocks for controlling water supply to each water supply hose connected to the water sprinkling pipes in each row. Then, the sprinkling area can be freely changed as necessary by switching the opening / closing cock. This automatic watering device is of a water supply connection type, and the strength of the water flow can be adjusted by the valve opening of the faucet.

When watering a horticultural facility using this automatic watering device, a water supply hose may be connected to a water tap and water may be supplied while the open / close cock is set to an open position. Then, the water from the water channel reaches the watering pipe via the water supply hose, and the water falls from the fountain hole of the watering pipe and spouts out, so that the water is automatically sprayed on the plants in the horticultural facilities. In this case, the water supply hose can be connected to a water tap via a joint with a timer, and by setting the timer, water can be sprinkled automatically at a desired time for a desired time.

By using this watering device, even when it is desired to water the leaves of tall plants, water can be easily watered from above the plants. In addition, when additional flowerbeds are installed, simply adding another watering pipe to the existing watering pipe and extending it can easily respond to the expansion of the watering area. Further, since a plurality of watering pipes and fixing fittings are detachably mounted on the support member and can be used directly with the water supply, it can be assembled and disassembled in any place in a short time. In addition, there is no need to provide a high-output pump or pressure-resistant water supply pipe between the faucet and the sprinkling pipe, and the structure of the entire apparatus is simplified.
