Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an irrigation system that drips water to plants in a plurality of pots.

FIG. 1 shows this conventional example.

A plurality of plugs 2 are provided in the cylindrical main body 1, which is closed at one end and equipped with a pipe 12 for connection to a water pipe and a feed pipe 13 at the other end, and a socket 6 to be attached to the plug 2 is provided at one end. The ultra-thin trip tube 4 provided for this purpose has a drip nozzle 5 at the other end, and water is sent as droplets from the cylindrical body 1 through each tube 4 into a pot 15 in which a buzzle 5 is placed. It will be done. In an irrigation system with a set of multiple tubes, it is necessary to remove unused tubes and attach a lid 20 to the plug 2 or a stopper 21 to the nozzle 5, which makes handling difficult. In addition to being a hassle, it was also difficult to deal with the changes. In the figure, numeral 3 indicates a water passage hole that controls the amount of water passing through.

Of course, the drip nozzle 5 disclosed in Utility Model Application Publication No. 54-25438, which is also shown in Fig. 2, is fitted into the tip of the tube 4 and inserted all the way into the tube to open a minute opening for drip drip. Because it is designed to be closed,
Since there is no need to prepare a separate stopper 21, some effort can be saved, but it is still time-consuming because such work has to be done for each nozzle 5. The present invention has been made in view of these points, and its main purpose is to:
To provide a water irrigator which can easily adjust the number of tubes used among a set of multiple tubes by operating a single valve, and can also perform watering at the same time. It is in.

J Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

Figures 3 and 4 show an embodiment of the present invention, in which a cylindrical body 1 with an open upper end and a female thread provided on the inner surface has a lower end with a pipe 12 for connecting to a water pipe and a feed pipe. 13, and a plurality of plugs 2 are provided on the circumference 7 of the cylindrical body 1. A socket 6 screwed onto the plug 2 is provided at the other end of the ultra-thin trip tube 4 which has a drip nozzle 5 at one end. Further, the plurality of plugs 2 provided in the cylindrical body 1 are arranged so as to be shifted in the axial direction of the cylindrical body 1. Reference numeral 7 denotes a rod-shaped body that is screwed into the cylindrical body 1, and has a collar 19 at its upper end and a packing 14 that contacts the inner peripheral surface of the cylindrical body 1 and forms a valve 11 at its lower peripheral edge.

This packing 14 also serves to prevent the rod-shaped body 7 from coming off from the cylindrical body 1. However, the rod-shaped body 7 of the lever is
If the valve 11 is located at the top by screwing it back, the water channels to all the tubes 4 will be opened, and as the rod-shaped body 7 is screwed forward, the tube 4 located at the upper position will be connected to the cylindrical body 1. The waterway between them is being closed. Reference numeral 20 is a scale plate used when adjusting the number of lines.

Further, the rod-shaped body 7 is provided with a water inlet 8 passing through it in the axial direction, and an internal thread is cut at the upper end opening. If a water sprinkling nozzle 9 is attached to this female thread, it is possible to perform not only water sprinkling from the trip tube 4 but also water sprinkling at the same time. 10 is attached. Figure 6 shows how this irrigation system is used. A control box 16 is placed between the cylindrical main body 1 and the water pipe 17, and the control box 16 controls water supply for a certain period of time at a certain time. Irrigation is carried out by flushing water. As described above, in the present invention, the number of trip tubes used can be adjusted as desired, and in particular, this adjustment can be made by simply screwing the rod-shaped body forward and backward with respect to the cylindrical body. Needless to say, there is no need for a stopper or a lid, and the adjustment can be made in one place by operating a single member, so the adjustment work can be performed easily.
