AUTOMATIC WATER FEEDING SYSTEM FOR FARM LAND
To provide an automatic water feeding system for farm land, capable of bringing a water feed line into a substantially fully closed state surely, even when pebble or ballast is held between a cutoff valve and a valve chamber bottom surface.SOLUTION: There is provided an automatic water feeding system 10 for farm land which is provided in a halfway of a water feed line for guiding agricultural water to a farm land from an irrigation channel, the automatic water feeding system comprises: a plate-shaped cutoff valve 20 being movable in a vertical direction, closing the water feed line at a fully closed position to which the cutoff valve is lowered, and opening the water feed line at a full open position to which the cutoff valve is raised; a valve body storage part 30 for storing the cutoff valve 20 at the full open position; and a control device storage part 50 being provided on an above position of the valve body storage part 30 and controlling a vertical position of the cutoff valve 20. An outer periphery of the cutoff valve 20 in at least a lower side part in a height direction from a thickness direction, is formed of an isolated cell sponge and serves as an elastic body outer periphery 22 capable of elastically contacting a bottom face of the water feed line in lowering time of the cutoff valve 20.SELECTED DRAWING: Figure 2
【課題】小石や砂利などが、止水弁と弁室底面との間に挟み込まれても、給水路を確実に全閉に近い状態にすることができる農地自動給水装置を提供する。【解決手段】用水路から農地へ農業用水を導く給水路の途中に配置された農地自動給水装置１０は、上下方向移動可能に配置され、下降した全閉位置で給水路を閉じ、上昇した全開位置で給水路を開く板状体の止水弁２０と、全開位置での止水弁２０を収容する弁体収容部３０と、弁体収容部３０の上方位置に設けられ、止水弁２０の上下方向位置を制御する制御装置５２を収容する制御装置収容部５０と、を有してなり、止水弁２０の、厚さ方向から見て少なくとも高さ方向下側部分の外周が、独立気泡スポンジからなり、止水弁２０の下降時に、給水路の底面に弾力的に圧接可能な弾性体外周部２２とされている。【選択図】図２
