Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a terminal member used for drip irrigation of potted plants, fruit trees, plants, etc.

[Conventional technology]

In conventional drip irrigation, water is applied directly from overhead using a drip irrigation hose, or a drip nozzle attached to the end of a hose is inserted into the soil, and water is applied using this drip nozzle.

[Problem that the invention attempts to solve]

However, in both cases, since water is applied locally to a specific location, a certain amount of water and time are required for the water to be distributed throughout the pot, etc., and the water path is particularly undesirable.

Therefore, the purpose of this invention is to solve such problems, and to provide a terminal member for drip irrigation that can uniformly and simultaneously irrigate the entire object and has no water path. be.

[Means for Solving the Problems] In order to solve the above problems, this invention consists of a non-perforated tube-like object whose both ends are connected to the connection port of a connection pipe attached to the tip of the lead tube. The tube material was composed of a microporous rubber-like porous material having open cells.

[Effect]

Since this device has such a structure, the water flowing from the reed tube passes through the water inlet and flows into the tube-shaped end member, and the water supply pressure causes the water to flow through the numerous micropores throughout the tube. Drainage drips in a drip form. Therefore, although the amount of water droplets per micropore is small compared to conventional nozzle types, the water is evenly dripped over the entire tube, so the target is irrigated evenly and quickly. Moreover, since the sum of these water droplets becomes the necessary and sufficient amount of water for the object, the amount of water can be significantly reduced compared to the conventional method, realizing economic efficiency. In addition, since the amount of water droplets from one micropore is small, it has a unique effect in that water cannot be found anywhere.

〔Example〕

In FIG. 1, 1 is a tube-shaped end member having water inlets 2 at both ends. This terminal member 1
is made of a relatively hard elastomer material, and has micropores 3 that are connected to the hollow interior of the tube as open cells.
is formed throughout the tube.

Therefore, as shown in FIG. 2, this terminal member 1 does not have a so-called nozzle hole that is specially drilled as in the conventional case, and the tube as a whole is in a closed state.
If the water inlets 2 at both ends of this terminal member 1 are connected to,
Water supplied from the water supply main pipe 4 and passed through the reed tube 5 fills the entire tube-shaped end member 1, and when the water supply pressure reaches a constant pressure, water is dripped through the micropores 3. Ru.

In this embodiment, since the terminal member 1 has the water inlets 2 at both ends, the reed tube 5 is provided with a connecting pipe 5a at its distal end that has two connecting ports that connect to both the water inlets 2. For example, only one end of the terminal member 1 may be used as the water inlet 2, and the other end may be closed, or the outlet may be closed only when in use.
Further, for example, the tube-shaped end member may be formed into an endless ring, and a water inlet may be formed in a part of the ring, or a connecting portion with the lead tube may be provided in a protruding manner. In short, any tube material may be used as long as it has a water inlet and has a structure in which water is dripped through the micropores 3 by the water supply pressure during irrigation.

By the way, regarding the material of this tube-shaped end member 1, the idea of this invention is to allow water to drip to the outside through the micropores by the water supply pressure flowing into the tube in the closed state. From this point of view, any microporous material having open cells can be used. For example, there are plastic foam materials and microporous rubber materials having such a structure. Alternatively, materials mainly composed of plastic films and textiles that are breathable and waterproof can also be used, as long as the micropores that maintain breathability become drainage holes due to the water supply pressure. However, in this embodiment, as mentioned above, the end member itself must have a certain shape retention property, and on the other hand, it has a certain rubber elasticity to make the drip amount extremely small, and from the viewpoint of durability, it is made of hard material. elastomer material is used, but it goes without saying that the configuration is not limited to this.

Incidentally, using the terminal member according to the above example, 50
When we tested watering in the pots, the amount of water was 1/20 compared to normal overhead irrigation, and the same amount of water came out for each pot, and the pots were evenly and evenly watered. There was also no access to water.

[Effect of idea]

As mentioned above, this invention uses a non-perforated tube-like object made of a microporous material with open cells as the end member, so that water is applied through the micropores throughout the tube, which improves uniformity and speed of irrigation. It is highly practical as it is efficient and economical, and also provides an irresistible water effect.
