[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply tool used for introducing water from a waterway into a paddy field.

[0002]

2. Description of the Related Art A straight pipe water supply tool 6 as shown in FIGS. 5 and 6 is used as a water supply tool for introducing water into a paddy field from a water channel adjacent to the paddy field. And this water supply tool 6 is arrange | positioned so that the waterway 7 and the paddy field 8 may be connected, and introduce | transduces the water of a waterway.

[0003]

Since the above-mentioned conventional water supply tool is a straight pipe, the water introduced from the water channel spouts into the paddy field vigorously. Therefore, there is a problem that the soil of the paddy field near the tip of the water supply pipe is dug up due to the fall of water from the water supply pipe, and the planted seedlings collapse, so that the seedlings near the water supply port do not grow and as a result the yield is affected. .

The present invention has been made in view of the above problems of the prior art, and its purpose is to provide a water supply tool capable of supplying water without digging up soil in a paddy field. To provide.

[0005]

In order to achieve the above-mentioned object, the water supply tool according to the present invention has a water discharge pipe connected to a water channel in a plane T-shape at the tip of the water supply pipe, and both side openings of the water discharge pipe. A baffle plate is provided in the conduit leading to the section. The baffle plate provided in the above-mentioned conduit may be one or a plurality of baffles as long as it can weaken the force of water discharge. As a form of the baffle plate, a substantially semicircular flat plate,
Alternatively, a doughnut-shaped flat plate or the like may be used, and these are set and fixed in the pipe line at a predetermined interval.

[0006]

According to the above means, the water introduced into the water supply pipe is
It hits a water discharge pipe connected in a T-shape, diverts it to the left and right, and is supplied to a paddy field from both openings of the water discharge pipe. Then, in the water discharge pipe, the force of water is weakened by the baffle plate and water is supplied from the tip of the water discharge pipe.

[0007]

Embodiments of the present invention will now be described with reference to the drawings. In the drawings, 1 is a water supply pipe, 2 is a water discharge pipe, 3 is a baffle plate, 4
Is a waterway and 5 is a paddy field. The water supply pipe 1 is made of a synthetic resin pipe, for example, a vinyl chloride pipe, and is formed to have a length capable of connecting the water channel and the paddy field. And is formed in a plane T shape.

Similar to the water supply pipe 1, the water discharge pipe 2 is made of synthetic resin, and two baffle plates 3 are staggered in the pipe passage extending from the connection with the water supply pipe 1 to the openings on both sides. Is stuck to. The baffle plate 3 is a flat plate having a substantially semicircular shape and is attached so that the straight sides are oriented in the vertical direction, and the water flow meanders to be discharged from the openings on both sides, thereby weakening the force of the water. Water is supplied from the tip of the water discharge pipe.

FIGS. 3 and 4 show another embodiment of the baffle plate installed inside the water discharge pipe 2, and the baffle plate 3 installed inside the pipe line.
′ Is formed into a donut shape, and the force of water is weakened by narrowing the diameter of the pipe line at the baffle plate 3 ′, and water is supplied from the tip of the water discharge pipe.

[0010]

The paddy field water supply device of the present invention is such that the water discharge pipe is connected to the tip of the water supply pipe in a flat T shape, and the baffle plate is provided in the conduit leading to both side openings of the water discharge pipe. Therefore, the water introduced into the water supply pipe from the waterway hits the water discharge pipe and is divided into left and right, and the flow of the divided water is weakened by the baffle plate in the pipeway and supplied to the paddy field from both sides of the water discharge pipe. It
That is, since the water supplied to the paddy field is weakened, the soil of the paddy field is not dug up, and thus the seedlings planted near the water supply port grow like other seedlings. Therefore, it is possible to provide a water supply tool that does not hinder the growth of seedlings.
