本考案は農業用、主として水田の水位調節装置に関する
もので、水田の水位を極めて簡単に調節で゛きるように
することを目的とする。[Detailed Description of the Invention] The present invention relates to a water level adjusting device for agricultural use, mainly in paddy fields, and its purpose is to make it possible to adjust the water level in paddy fields extremely easily.
従来水田の水位の調節は、畦を切ったり或いは木材板で
仕切ったりして排水口の高さを調節することにより行な
われ、農家の人は毎朝夕、水田の水管理のために、浅水
がないかどうかを確認に行っていた。Traditionally, the water level in rice fields has been adjusted by cutting ridges or partitioning them with wooden boards to adjust the height of drainage holes. Farmers have to check shallow water every morning and evening to manage the water in their rice fields. I went to check to see if it was there.
本考案はこのような浅水を確実に防止して浅水の有無を
確認する手間を省き、しかも水田の水位を極めて簡単に
調節できる水位調節装置を提供せんとするもので、以下
本考案を実施の一例を示す図面に基づいて説明する。The present invention aims to provide a water level adjustment device that can reliably prevent such shallow water from occurring, save the trouble of checking the presence or absence of shallow water, and that can extremely easily adjust the water level in rice fields. An example will be explained based on drawings.

っている。Note that the inner and outer diameters of the piston 10 and the inner and outer diameters of the cylinder 9 are equal, and in order to fit the piston 10 into the cylinder 9, the piston 10 has a split groove 12 formed at its rear side. The piston 10 is compressed so that its diameter becomes slightly smaller using the split groove 12, and can be press-fitted into the cylinder 9 with an appropriate force.
又ピストン10の上端部において前側部と後側部の高さ
が異なり、前側部の高さは後側部の高さよりも低く且つ
後側部の一つ割り溝部12の高さ中間部に形成された排
水孔13の高さよりも高くなるように形成されている。Further, at the upper end of the piston 10, the heights of the front side part and the rear side part are different, and the height of the front side part is lower than the height of the rear side part, and is formed at the middle part of the height of the single groove part 12 on the rear side. The height of the drain hole 13 is higher than that of the drain hole 13.
又前記シリンダー9の上端部は側面形状がぺ状即ち前側

置して開口可能に形成されている(第5図参照)。The upper end of the cylinder 9 has a flat side surface shape, that is, is formed so that the height gradually increases from the front upper end to the rear upper end, and when the piston 10 is fitted into the cylinder 9 to the lower end, the piston The front upper end of the cylinder 91 is higher than the front upper end of the cylinder 9 (see Figure 3), and the drain hole 13 of the piston 10 is located at the front upper end of the cylinder 91 and is openable (see Figure 5). ).
次にこの水位調節装置5の使用方法について説明する。Next, a method of using this water level adjusting device 5 will be explained.
水位調節装置5は第3図に示すように水田の端部におい
て畦4に近接して設けられる。The water level adjustment device 5 is provided close to the ridge 4 at the end of the rice field, as shown in FIG.
詳しくはシリンダー9は後側部は畦4側に、前側部は水
田側に向くように且つ前側上端部が作土2内に若干埋没
するように埋め込まれると共にエルボ7及び排水管8も
畦4の下側で床上1内に埋め込まれ、排水管8の他端部
には一端部が前記排水溝6に開口する別の排水管14の
他端部が嵌合連結されている。Specifically, the cylinder 9 is buried so that the rear part faces the ridge 4 side, the front part faces the paddy field side, and the front upper end is slightly buried in the soil 2, and the elbow 7 and the drain pipe 8 are also buried in the ridge 4 side. The other end of the drain pipe 8 is fitted and connected to the other end of another drain pipe 14 whose one end opens into the drain groove 6.
前記ピストン10は前記シリンダー9内に上方より嵌入
され、前側部を水田(作土2)側に向かせておくことに
よりピストン10の前側上端部は作土2よりも上方に突
出して作土2上の水3の洩れを防止することができる。The piston 10 is fitted into the cylinder 9 from above, and by keeping the front side facing the paddy field (cultivated soil 2) side, the front upper end of the piston 10 protrudes above the cultivated soil 2, and the cultivated soil 2. It is possible to prevent the water 3 above from leaking.
又第4図に示すようにピストン10を引き上げてその前
側上端部を第3図よりも上方に位置させることにより作
土2上の水位を高い状態に保つことができる。Further, as shown in FIG. 4, by pulling up the piston 10 and positioning its front upper end above the position shown in FIG. 3, the water level above the soil 2 can be maintained at a high level.
尚降雨等により作土2上の水3が増える場合はその増水
骨を前記ピストン10の前側上端部からピストン10内
に水3を導き、エルボ7→排水管8,14→排水溝6の
順で排水することができる。If the water 3 on the soil 2 increases due to rainfall, etc., the water 3 is guided into the piston 10 from the front upper end of the piston 10 in the order of elbow 7 → drain pipes 8, 14 → drain groove 6. can be drained.
更に作土2上の水位を下げたい場合は例えば第4図の状

→排水溝6へと完全排水することができる。By the way, if you want to drain water from soil 2, please refer to Figures 4 and 5.
As shown in the figure, by rotating the piston 10 by 180 degrees and pushing it all the way to the lower end of the cylinder 9, the drain hole 1 is opened.
3 faces the soil 2 side, and the water 3 on the soil 2 is guided into the piston 10 through this drainage hole 13, and the elbow 7 → drain pipes 8, 14
→It is possible to completely drain water to the drain groove 6.
尚以上実施例では排水管8に別の排水管14をつないだ
が、畦4の狭い場合は排水管8を排水溝6に開口させる
ことができ、この場合は排水管14を設ける必要がない
。In the above embodiments, the drain pipe 8 is connected to another drain pipe 14, but if the ridge 4 is narrow, the drain pipe 8 can be opened into the drain groove 6, and in this case, it is not necessary to provide the drain pipe 14.
