A system to automatically irrigate all paddy fields in an irrigation network.

摘要

Problem to be solved: to provide a water system for automatically filling all paddy fields from agricultural waterways or drainage and irrigation channels.The water supply system in an agricultural waterway is equipped with a mountain dividing ditch 14 which is divided vertically by the ratio of the area of the paddy field where the tributary takes charge at the branch point of the waterway 6, and when the paddy field becomes full water, the automatic water supply in which the multiple valves are interlocked by the float and the water intake is automatically stopped by the float It is equipped with a stopper, and a water level variable overflow weir that can easily adjust the water level of the channel to the water level at the time of full water of each paddy field can be easily adjusted by the superposition of the weir board, and all the fields in the watershed are automatically filled with water.The divided flow ditch 14 passes from the apex 11 downstream of the bifurcation point of the waterway 6, the overflow dam 12, which is higher than the overflow overflow weir 8 attached to the waterway, and the dividing Guide 14 which has welded the iron plate to the El guide to the upper guide 13, and it is fixed by the screw 15 so as to be proportional to the area of the paddy field downstream of the channel Set.Diagram
