Install a gate block (B) that has a drainage port (2) for adjusting the water depth in (water bottom),
The present invention relates to an automatic irrigation method for irrigation water, which connects the both with a control water pipe (6) to secure a constant water level in a paddy field, completely prevent excessive water intake and ineffective discharge, and automatically activate effective use of rainwater.

水尻においての考慮は一切なされていない。Conventionally, as an automatic irrigation device for paddy fields, an automatic control device that is generally composed of a water tap discharge port and a water level detection unit has been developed, but this device was installed at the water supply port side (water port) of a paddy field. In order to manage the water level, the water level detector detects the water level in the vicinity of the water outlet to perform irrigation and water stoppage, resulting in excessive frequency of operation and the tendency to cause chattering. As the wear of the paddy increases, malfunctions are likely to occur, and only the water level is controlled, and no consideration is given to the paddy field in the paddy field.

自動的に止水し、また、水面が設定水位より自然に下が
ると、自動的に灌水させるようにした。The means for solving the above problems will be described with reference to FIG. 1 corresponding to the embodiment. According to the present invention, the water supply is provided with a diaphragm (1) at the discharge port of the irrigation water supply pipe 1a for paddy fields. A gate block (5) provided with a stopper (A), a drainage port (2), a movable gate (3) having a drainage port (2), and a ball tap valve (5) that is opened and closed by interlocking with a float (4). B) and The water tap (A) and the ball tap valve (5) provided on the falling water side at a distance,
By connecting with the control water pipe (6), during irrigation, the float (4) is raised and the irrigation is automatically performed while forming a running water gradient from the water discharge port side toward the drain port (2). The water was stopped, and when the water surface naturally fell below the set water level, water was automatically supplied.

せ、その距離と勾配を利用することにある。The remarkable difference between the conventional automatic water supply means and the irrigation means in the present invention described above is that in the conventional method, control is performed on the side of the faucet (water port), whereas in the present invention, A water tap is provided at the water mouth, a gate block (B) equipped with a ball tap valve (5) is installed at the bottom of the paddy field, and the water tap (A) and the ball tap valve (5) are connected by a control water pipe (6). , It is to form a running water gradient on the water surface between them and to use the distance and the gradient.

水（比重の重い水）を放流させないで、降雨の際には余
剰な雨水（比重の軽い水）のみを放流することが出来
る。In the present invention, the reason why the gate block (B) provided with the ball tap valve (5) is installed at the bottom of the paddy field is that the control is performed by installing the device at the water outlet as in the conventional method.
At the time of starting irrigation for the first time, it takes time and labor to match the height of the overflow weir at the water end with the height of the device at the water mouth. If it is low, it will be an ineffective discharge, and if it is high, it will cause inconvenience such as excessive deep water at the time of rainfall, so it will be eliminated and water containing fertilizer components and pesticides (water with a high specific gravity) ) Is not released, and only excess rainwater (water with a low specific gravity) can be released during rainfall.

る。In addition, by using distance and running water gradient, it is possible to prevent excessive operation frequency and chattering, at the same time secure a certain water level and completely prevent excessive water intake and ineffective discharge, and at the same time By ensuring the water level, preventing excessive water intake and ineffective discharge completely, and by providing a difference between the height of the drainage line of the float (4) and the drainage port (2), it is possible to positively control rainwater during rainfall. It can be used.

水勾配が生じる、この勾配を保ちながら、その水深を増
す、所定の水位に達すると、前記第１図の説明に従って
灌水を自動的に止める。To prevent excessive actuation frequency and chattering by using distance and running water gradient, when starting irrigation from the hydrant (A), from the position of the hydrant (A) to the drainage port (2), There is a gradient on the water surface. When irrigation starts from the water tap (A), a running water gradient is formed on the water surface in a slightly concentric manner toward the outer periphery with the water tap (A) as the center. In the case of paddy rice fields, resistance is added to the flow of water especially by the rice stock and as the rice stock grows, and the water surface is proportional to the distance from the water tap (A) to the drainage port (2) and the discharge rate. There is a difference in elevation, and therefore a water flow gradient occurs on the surface of the rice field toward the drainage port (2) provided at the farthest end of the paddy field. While maintaining this gradient, the water depth increases, and when a predetermined water level is reached. , The irrigation is automatically stopped according to the explanation of FIG.

を増し、誤作動が起こらず、過剰な作動頻度或るいは、
チャタリング現象を防止する。When the irrigation is stopped, the water surface of the rice field gradually recovers level while being resisted by the movement of water by the rice stock. The level of the water surface is restored to the horizontal level on the side of the hydrant (A). On the contrary, on the drain (2) side, the water surface rises to the horizontal surface. Due to the float of the float (4),
Ball tap valve (5) closed (float (4)
(The water surface has reached the water line up to), and only the water surface rises and recovers the horizontal level. As a result, the buoyancy of the float (4) is increased, no malfunction occurs, and excessive operation frequency or
Prevent chattering phenomenon.

きる。Also, due to the reduced depth of water in the paddy field, malfunction or chattering is likely to occur even at the moment when irrigation is about to begin, but when the ball tap valve (5) is about to open, the control water pipe (6) becomes stationary. The water started to flow, and by giving a distance to the water flow, velocity energy is added, and water pressure acts on the ball tap valve (5) in a direction to open it further, and it is expected that chattering will be prevented. .

By inserting the stopper (s) in (3a), the gate is fixed and the water level of the paddy is set.

用水主流（Ｃ）を閉止する。When the water level of the rice field is lower than the set water level, irrigation is started from the C part of the hydrant (A) according to the explanation of Fig. 1. When irrigation starts, a running water gradient is generated from the water outlet toward the tail. When the water level of the rice field rises and reaches a predetermined water level, the float (4) is interlocked to close the valve seat of the ball tap valve (5), which fills the diaphragm chamber (a) of the water tap (A). Push down the diaphragm (1),
Close the main water flow (C).
この作用は、ダイヤフラム（１）上面の受圧面積が下
面受圧面積より大きく、その面積の差cm2×水圧kgf/cm2
の背圧がダイヤフラム上面に働くからである。This is because the pressure-receiving area on the upper surface of the diaphragm (1) is larger than the pressure-receiving area on the lower surface, and the difference between the areas cm 2 × water pressure kgf / cm 2
This is because the back pressure on the diaphragm acts on the upper surface of the diaphragm.

面に灌水を続ける。When the water level in the rice field falls below the set water level, the ball tap valve (5) is opened by the interlocking movement of the float (4), and the water pressure in the diaphragm chamber is lowered, and the diaphragm (1) is pushed up by the water pressure for full opening. , Continue watering the rice field.

Automatically repeats the closing operation again to maintain the water level.
