[Industrial application field]

The present invention relates to an irrigation system, and more specifically, to an irrigation system used for cultivating crops in greenhouse horticulture and the like.

[Conventional technology]

In the field of agriculture and horticulture, hydroponic cultivation used to mostly use the nutrient circulation method, but recently, the continuous flow method has been increasingly used, as seen in sand cultivation, rock wool cultivation, etc. What is important in this continuous flow system is to apply a uniform amount of water without variation to each of the many irrigation points arranged in the longitudinal direction of a long cultivation bed.

Examples of this type of irrigation equipment include
The one shown in Publication No. 32754 is known. In this conventional irrigation system, as shown in FIG. 5, for example, an irrigation pipe 1 with a diameter of approximately 20 mm is laid along the longitudinal direction of the cultivation bed 4. By inserting one end of a flexible drip tube 2 on the water supply port side, which is extremely thin compared to the pipe 1, and having an inner diameter of approximately 1 mm, a large number of tubes are attached at appropriate intervals, and the drip tube 2 is placed on the drip port side of the drip tube 2. The other end is placed above the irrigation pipe 1 to irrigate the cultivation bed 4. In this irrigation device, a filamentous body 9 is disposed above the cultivation bed 4 in the longitudinal direction, the end of the drip tube 2 on the side of the drip port is attached to the filamentous body 9, and the filamentous body 3 is stretched on both ends. is fixed to a stake 6 (for example, a pillar driven into the ground).

Even if the surface of the cultivation bed is uneven or the cultivation bed is tilted in the longitudinal direction, the above device can drip evenly by applying an appropriate inclination to the filament, and is highly responsive to irrigation commands. It has the advantage of being good.

[Problem that the invention attempts to solve]

However, the conventional device described above has a problem in that the filamentous body is stretched over the cultivation bed, which obstructs the operation of the cultivation bed, and the filamentous body is stretched in the longitudinal direction of the cultivation bed. Therefore, in order to remove it to the side of the cultivation bed, it must be carried out over the entire length of the cultivation bed, making it unsuitable for working on a partial area within the cultivation bed. The dot was hot.

The present invention aims to solve the above-mentioned problems of the conventional apparatus and provide an irrigation apparatus that is easier to use.

[Means for solving problems]

According to the present invention, the above problem can be solved by inserting the water inlet side of multiple drip tubes made of flexible material and having very small inner diameters compared to the irrigation pipe into the irrigation pipe at appropriate intervals. This problem can be solved by equipping the irrigation device with a plurality of rod-shaped bodies to which the ends of the drip tubes of the drip tubes are fixed at appropriate intervals, and placing the plurality of rod-shaped bodies on top of the cultivation bed. Ru.

[Effect]

In an irrigation system, the drip ports of the multiple drip tubes are inserted into the irrigation pipes at appropriate intervals with the water supply ports of multiple drip tubes made of flexible material and having inner diameters that are much smaller than those of the irrigation pipes. A plurality of rod-shaped bodies with side tips fixed at appropriate intervals are placed on top of the cultivation bed, and the cultivation bed is uniformly irrigated with the nutrient solution from the irrigation pipe through the drip tube. By moving the drip tube fixed to the body to the side of the cultivation bed and removing it, temporarily removing obstacles to work from the surface of the cultivation bed and preparing for work, and temporarily removing it after work is completed. By returning the rod-shaped body together with the drip tube to its original position, the effort involved in preparing for work and returning to the original state is reduced.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention. In the figure, 1 is an irrigation pipe, 2 is a drip tube, 3 is a rod-shaped body, 4 is a cultivation bed, and 8 is a stand for the cultivation bed 4.

Irrigation pipe 1 with a diameter of approximately 20 mm as shown in the diagram
is laid along the longitudinal direction at the bottom of the cultivation bed 4 placed on the stand 8, and the irrigation pipe 1 has a flexible pipe that is very thin compared to the irrigation pipe 1, for example, with an inner diameter of about 1 mm, in the longitudinal direction. By inserting one end of the drip tube 2 made of plastic material on the water supply port side, a large number of drip tubes 2 are attached at appropriate intervals, and the other end 2b of the drip tube 2 on the drip port side is placed longitudinally at the top of the cultivation bed 4. They are attached at appropriate intervals to a plurality of rod-like bodies 3 having appropriate lengths placed along the direction.

The 2b end of the drip tube 2 may be attached to the rod-shaped body 3 by any means.

FIG. 2 is a perspective view of an example of the rod-shaped body 3, and in the figure, 3 indicates the main body of the rod-shaped body, and 6 indicates a projection provided on the rod-shaped body 3. Usually, a plurality of these projections 6 are provided, By inserting this into the culture medium of the cultivation bed 4, the rod-shaped body 3 can be fixed to the cultivation bed 4.
