WATER LEVEL ADJUSTMENT DEVICE FOR PADDY FIELD
To provide a water level adjustment device for paddy field configured to securely support a dam plate in a raised state so as to perform quick release of paddy water, so as to prevent a dam plate from falling due to water pressure, and so as to prevent loss and theft of the dam plate, so that farming operation of rice cultivation can be performed smoothly and efficiently with confidence.SOLUTION: A basin main body 2 has a configuration in which a rear plate 2B having a drainage hole 2D and a pair of side plates 2C are erected on a bottom plate 2A in a substantially square shape in a plan view. A pressure receiving plate 3 is provided on a lower front side in the basin main body 2, and a water level adjusting plate 4 is provided so as to be variable in height and detachable while being in surface contact with the pressure receiving plate 3. Between the rear plate 2B and the water level adjustment plate 4, a dam plate 5 formed of a flat plate provided with a water discharge hole 5C smaller in diameter than the drainage hole 2D at the lower side than the water level adjustment plate 4 is provided vertically movably. A dam plate support 6 formed of a chain is connected between the dam plate 5 and the rear plate 2B.SELECTED DRAWING: Figure 5
【課題】ダム板を引き上げた状態に確実に支持する構成にしたから、水田水の速やかな放出を実行できるし、水圧によってダム板が転倒する事態も解消でき、かつダム板の紛失や盗難を防止できるので、稲作の農作業を円滑かつ効率的に、また安心して行うことができるようにした水田用水位調整装置を提供する。【解決手段】桝本体２は、排水穴２Ｄを有する後板２Ｂ及び一対の側板２Ｃを底板２Ａに平面視で略冂字状に立設した構成からなる。桝本体２内には、前方下部側に受圧板３を配設し、受圧板３に面接触した状態で水位調整板４が高さを可変に、かつ嵌脱可能に配設してある。後板２Ｂと水位調整板４との間に、水位調整板４より背高で、下部側に排水穴２Ｄより小径の放水穴５Ｃを設けた平板からなるダム板５が昇降可能に配設してある。ダム板５と後板２Ｂとの間に鎖で形成したダム板支持体６が連結してある。【選択図】図５
