この発明は、圃場の灌水技術に関連するあらゆる分野をその技術分野とするものであり、水路や水田等に水口を施設する分野は勿論のこと、その製造および設置に必要となる設備、器具類を提供、販売する分野から、それら資材や機械装置、部品類に必要となる素材、例えば、木材、石材、各種繊維類、プラスチック、各種金属材料等を提供する分野、それらに組み込まれる電子部品やそれらを集積した制御関連機器の分野、各種計測器の分野、当該設備、器具を動かす動力機械の分野、そのエネルギーとなる電力やエネルギー源である電気、オイルの分野といった一般的に産業機械と総称されている分野、更には、それら設備、器具類を試験、研究したり、それらの展示、販売、輸出入に係わる分野、将又、それらの使用の結果やそれを造るための設備、器具類の運転に伴って発生するゴミ屑の回収、運搬等に係わる分野、それらゴミ屑を効率的に再利用するリサイクル分野などの外、現時点で想定できない新たな分野までと、関連しない技術分野はない程である。     This invention has all fields related to irrigation technology in fields as its technical field, not to mention the field of installing water outlets in waterways, paddy fields, etc., as well as equipment and tools necessary for its manufacture and installation. From the field of providing and selling materials, machinery, and materials required for parts, such as wood, stone, various fibers, plastics, various metal materials, etc. The general term for industrial machinery such as the field of control-related equipment that integrates them, the field of various measuring instruments, the field of power equipment that moves the equipment and instruments, the field of electricity and energy that is the energy source, and oil. In addition to testing, researching these facilities and equipment, fields related to their display, sales, import / export, general results, and the results of their use. To the new fields that can not be envisaged at the present time, other than the fields related to the collection and transportation of garbage debris generated by the operation of equipment, equipment, etc., the recycling field that efficiently recycles these garbage debris, etc. There are no unrelated technical fields.

(着目点)
水稲栽培における間断灌水等の水管理は、水田の上流側となる土畦の一部と、下流側土畦の一部とに水口を開口し、夫々の開閉操作ならびに水尻の水深調節等を適正に行う必要があり、従前までは、これらの水口に肥料袋に土を詰めた土嚢や比較的大きな石等の複数個を充填状に配置させ、隙間に泥を詰める等して水密状に閉鎖し、開放する際には手作業によって土嚢や石を取り除き、再度閉鎖する際には充填状に配置させ、それらの充填高さによって圃場の水深を調節するというのが一般的であった。
(Points of interest)
Water management, such as intermittent irrigation in paddy rice cultivation, opens a water outlet to a part of the soil on the upstream side of the paddy field and a part of the downstream side of the paddy field. Until now, these water outlets were closed in a watertight manner by placing a plurality of sandbags filled with fertilizer bags with soil, relatively large stones, etc., and filling the gaps with mud. However, sandbags and stones are manually removed when opening, and are placed in a filling state when closing again, and the water depth of the field is generally adjusted by their filling height.

このような従来型の灌水管理は、開閉操作の毎に比較的重量の嵩む土嚢や石等を持ち上げて移動させ、閉鎖の際には、土嚢同士や石同士および畦水尻との隙間に泥を詰める等の煩雑で負担の大きな作業が不可欠な上、適正な水深に調節するのにも、土嚢や石の配置を何度も換えて調整しなければならず、多大な時間と労力とを要しており、これら充填物の形状が一定でないため、水没部分における漏水の確認も難しく、頻繁に農圃を見回らなくてはならず、十分な時間を取れない兼業農家等にあっては正確な水管理をあきらめ、通勤前後という朝夕の限られた時間に僅かな修正を加える程度に留めざるを得ないという状況となっていた。     In such conventional irrigation management, sandbags and stones that are relatively heavy are lifted and moved each time opening and closing operations, and mud is placed in the gaps between sandbags, stones, and flooded butt when closed. In addition to complicated and heavy work such as packing, it is necessary to change the arrangement of sandbags and stones many times in order to adjust the water depth to an appropriate depth, which requires a lot of time and labor. Since the shape of these fillings is not constant, it is difficult to check for water leaks in the submerged area, and it is necessary to look around the farm frequently. As a result, they had to give up their water management and make a slight correction to the limited hours of morning and evening before and after commuting.

さらに、土嚢や石による水口の閉鎖は、降雨等による増水に起因する給排水量の増加等によって水口との境や泥を詰めた隙間等が洗掘され、必要量を大幅に超える量の水が流入してしまい、さらに、その後の流失によって十分な灌水が行われなくなってしまうことがある外、前年の収穫後に土中に透き込んだ稲藁の一部や、除草された草等が水面に浮いて水尻に流れ、用水路に流出して下流側の水を汚すことがあり、また、同様に外部のゴミ等が用水路を通じて圃場に流入してしまい、苗を倒したり稲に傷を付ける等の弊害を生じることもあり、多くの改善点が残されていると云わざるを得ないものであった。     Furthermore, the closure of the water mouth by sandbags or stones scoured the boundary with the water mouth or gaps filled with mud due to an increase in the amount of water supply and drainage caused by the increase in water due to rainfall, etc. In addition, there may be cases where sufficient irrigation may not be performed due to subsequent loss, and some rice straw that has penetrated the soil after the previous year's harvest, or weeded grass, etc. on the surface of the water. It floats and flows into the water bottom, may flow out into the irrigation channel and pollute the water on the downstream side.Similarly, external garbage may flow into the field through the irrigation channel, causing the seedlings to be killed or the rice to be damaged. It may cause harmful effects, and it must be said that many improvements have been left.

(従来の技術)
そうした中にも、その打開策となるようなものとして、例えば特開平9−163879号公報「水田用給排水口」発明として提案されているもののように、周囲枠裏面側に縦・横リブを直交させるよう形成して十分に補強し、下部周面部の前縁から断面L字形の埋込み支持部を垂下させ、中央に開口した開口部の裏面左右に互いに向かい合う一対のガイド溝を形成し、畦に沿って縦に埋設されるゲート部材と、裏面側に縦・横リブを直交させるよう形成して十分に補強し、左右の側縁部を上記ガイド溝に対して昇降可能に、且つ密に嵌合させる堰板との合成樹脂製の二部材からなり、圃場の水口に埋設したゲート部材に対し、堰板を昇降操作することによって該堰板の下端とゲート部材下側枠部分との間に開口される流水口を通じて通水可能とし、堰板の開度によって流量を調節できるようにしたものや、特開2003−55947号公報「水田用給水ゲート」発明の、上端から下端に亘って空隙部が設けられたゲート本体に取水口を穿設し、前記空隙部に取水口を開閉するゲート板が昇降可能に挿通されると共に、取水口に網状体を設けたものとし、畦の水口に突き刺して利用可能として網状体がゴミや草等の浮遊物の通過を阻止できるようにしたものがある。
(Conventional technology)
Among them, vertical and horizontal ribs are orthogonal to the back side of the peripheral frame, such as the one proposed in Japanese Patent Application Laid-Open No. 9-163879, “Water Supply / Drainage Port for Paddy Fields”. It is formed so that it is sufficiently reinforced, and an embedded support portion having an L-shaped cross section is suspended from the front edge of the lower peripheral surface portion, and a pair of guide grooves facing each other on the left and right sides of the opening portion opened in the center is formed. The gate member embedded vertically and the vertical and horizontal ribs on the back side are formed to be orthogonal and sufficiently reinforced, and the left and right side edges can be raised and lowered with respect to the guide groove and tightly fitted. It consists of two members made of synthetic resin with the weir plate to be combined, and by raising and lowering the weir plate with respect to the gate member embedded in the water mouth of the field, between the lower end of the weir plate and the lower frame part of the gate member Water can be passed through the open water outlet The flow rate can be adjusted according to the opening of the weir plate, and the gate body provided with a gap from the upper end to the lower end of the invention disclosed in Japanese Patent Application Laid-Open No. 2003-55947, “Water Supply Gate for Paddy Fields”. A gate plate that opens and closes the water intake port is inserted in the gap so as to be able to move up and down, and a mesh body is provided at the water intake port. There are things that can prevent the passage of floating objects such as grass and grass.

また、特開平9−140279号公報「排水弁」発明に開示されたもののように、保護筒体の側壁の所定位置に排水口を設け、底壁に穿設された貫通孔と連通すると共に、該底壁上に伸縮可能な蛇腹部を有する排水筒を垂設し、該排水筒の上端から立ち上げた連結棒を保護筒体の上方に設けた係止部材に挿通して上下動可能に保持する一方、保護筒体の底壁下面に、垂直水路、第1水平水路、第2水平水路を備えた補助桝を接続したものとし、伸縮性を有する蛇腹部が、排水筒の高さ調節を可能とし、泥や浮きゴミ等が排水筒内に流入しても作動不能となることがなく、田面水位を所定の高さに設定することができ、しかも装置全体がコンパクトとなり、水田への設置、施工作業が簡単に行なえるようにしたもの、あるいは、用水路に面した水口にゴミや草などの浮遊物が侵入するのを防ぐようにする技術として、特開平9−74931号公報「用水路における水田用給水口の目詰まり防止装置」発明のように、給水口が開口する用水路の水路壁に沿って上流側から下流側に向けて該水路壁から漸次離れる様に配する侵入防護体と、この侵入防護体を水路壁に着脱可能に保持する掛止金具とからなり、用水路中を流下するゴミや草等の浮遊物が給水口に侵入しないよう下流側へと誘導する技術等が散見される。     In addition, as disclosed in Japanese Patent Application Laid-Open No. 9-140279 “Drainage Valve”, a drainage port is provided at a predetermined position on the side wall of the protective cylinder, and communicates with a through-hole drilled in the bottom wall. A drainage cylinder having a bellows part that can expand and contract on the bottom wall is suspended, and a connecting rod raised from the upper end of the drainage cylinder is inserted into a locking member provided above the protective cylinder so that it can move up and down. On the other hand, an auxiliary rod provided with a vertical water channel, a first horizontal water channel, and a second horizontal water channel is connected to the bottom surface of the bottom wall of the protective cylinder, and the bellows portion having elasticity is used to adjust the height of the drain tube. Even if mud or floating dust flows into the drain, it does not become inoperable, the surface water level can be set to a predetermined height, and the whole device becomes compact, Easy installation and construction work, or facing the waterway As a technique for preventing the invasion of floating substances such as dust and grass into the mouth, the water inlet is opened as disclosed in Japanese Patent Application Laid-Open No. 9-74331 “A device for preventing clogging of a water inlet for paddy fields in a water channel”. An intrusion protective body arranged so as to gradually move away from the water channel wall from the upstream side to the downstream side along the water channel wall of the irrigation channel, and a latch fitting for detachably holding the intrusion protective body on the water channel wall. In addition, there are some techniques to guide downstream such as dust and grass floating in the waterway so that they do not enter the water supply port.

しかし、前者の「水田用給排水口」発明は、流水量の調節は可能であっても田面水深の調節ができない上、ゲート部材左右側端部と土畦水口との接合部分が洗掘に対して弱いことと、流水中に浮遊するゴミや草等を分離できないという欠点があり、二番目に示した「水田用給水ゲート」発明は、網状体が流水中の浮遊物を分離、除去できるものの、やはり水深の調節ができず、洗掘に対する設置強度も弱く、網状体にゴミが堰き止められた状態で水圧が高まると、網状体が破損したり、水田用給水ゲート自体が畦から離脱してしまう虞があり、水管理や降雨時など頻繁に確認しなければならないという欠点を拭いされないものであった。     However, the former “paddy water supply / drainage” invention does not allow adjustment of the water depth of the surface even though the flow rate can be adjusted, and the joint part between the left and right ends of the gate member and the soil water inlet is against scouring. And the disadvantage of being unable to separate dust, grass, etc. floating in the running water. The second “Water Supply Gate for Paddy Fields” invention is that the net can separate and remove floating substances in the running water. Also, the water depth cannot be adjusted, the installation strength against scouring is also weak, and if the water pressure increases with the dams dammed up in the mesh body, the mesh body will be damaged or the paddy water supply gate itself will come off from the dredging. There is a risk that it will not be wiped away from the drawbacks of frequent checks such as water management and rain.

また、三番目に示した「排水弁」発明は、ゴム製等の蛇腹部を伸縮させるようにして圃場の水深を所望の水位に調節することが可能となるようにした上、保護筒体内に流入した泥やゴミ、草等を簡便に排除することができ、ゴミ類の堰き止めを防止して円滑な流水を可能としてはいるが、複数年に渡って利用することを考慮すると、伸縮性および水密性を要する部分にゴム製等の比較的柔軟な素材を用いる構造は耐久強度に不安を残すものであり、或程度の期間使用した後には、蛇腹部が劣化、破損してしまうことも予想され、どうしても頻繁なメンテナンスや交換等が不可欠となって経済的にも不利なものであると云わざるを得ない。     In addition, the third “drainage valve” invention is such that the water depth of the field can be adjusted to a desired water level by expanding and contracting the bellows portion made of rubber or the like, and in the protective cylinder. Inflow mud, garbage, grass, etc. can be easily removed, preventing dams from blocking and allowing smooth water flow. In addition, the structure using a relatively flexible material such as rubber for parts that require watertightness leaves uncertain durability, and after a certain period of use, the bellows may deteriorate or break. As expected, frequent maintenance and replacement are indispensable, and it must be said that it is economically disadvantageous.

さらに、後者の「用水路における水田用給水口の目詰まり防止装置」発明は、用水路に面した水口に設置し、用水路中に浮遊しているゴミや草等が水田に流入するのを防止するようにしているが、流入水量の調節や堰き止め等を行うことはできず、前述の「水田用給排水口」発明や「水田用給水ゲート」発明等のような水口を、圃場側の給水口に追加、設置しなければならないものとなっていた。

Further, the latter “device for preventing clogging of the water supply port for paddy fields in the irrigation channel” is installed at the water port facing the irrigation channel so as to prevent dust, grass, etc. floating in the irrigation channel from flowing into the paddy field. However, it is not possible to adjust the amount of inflowing water or to prevent damming, etc., and use the water inlets as described above for the “paddy water supply / drainage” invention or the “paddy water supply gate” invention, etc. It had to be added and installed.

(Awareness of problems)
As mentioned above, including the previously proposed “paddy field water supply / drainage” invention, the “paddy field water gate” invention, the “drainage valve” invention, the “paddy field water supply port clogging prevention device in the irrigation channel” invention, etc. However, there is still room for improvement in terms of treatment of flowing garbage and grass, strength against scouring, water depth adjustment, durability of the members, management for maintaining functions, etc. It was something to leave.

(発明の目的)
そこで、この発明は、流水中を浮遊するゴミや草の通過を阻止し、開閉可能である上、水流量と圃場水深とを調節可能とし、洗掘への耐久強度にも秀れ、しかも比較的小型、軽量であって土畦水口への設置や撤去も容易に行うことができ、経済的にも秀れた新たな圃場用水口の開発はできないものかとの判断から、逸速くその開発、研究に着手し、長期に渡る試行錯誤と幾多の試作、実験とを繰り返してきた結果、今回、遂に新規な構造の水田用水口を実現化することに成功したものであり、以下では、図面に示すこの発明を代表する実施例と共に、その構成を詳述することとする。
(Object of invention)
Therefore, the present invention prevents the passage of dirt and grass floating in running water, can be opened and closed, and can adjust the water flow rate and field water depth, and also has excellent durability against scouring and comparison It is very small and lightweight, and can be easily installed and removed from the earth spillway, so that it is possible to develop a new farm irrigation that is economically superior. As a result of starting research and repeating trial and error over many years and many trial productions and experiments, we finally succeeded in realizing a paddy field paddy with a new structure. The configuration will be described in detail together with the embodiment which represents the present invention.

The bottom plate 2 is buried under the ground of the paddy field F and installed horizontally, and the back wall 31 is parallel and vertical to the 方向 R direction, and the connection sleeve 51 for the drain port 5 is already provided. Corresponding to and connected to the drain pipe B, the piles 22 and 22 are driven into the pile driving holes 21 and 21 respectively opened to the left and right of the bottom plate portion 2 shown in FIGS. The left and right debris loading spaces 6 and 6 on the top and bottom of the wing portion 7 and the bottom plate portion 2 are filled without any gaps, and the paddy field F side wall surface of the paddle R is formed on the front left and right outer sides of the calling plate portions 35 and 35. Backfill continuously so that the buried part of the ridge R is tamped and firmly fixed.

当該集水胴部3開放部4の左右レール溝36,36間に、所望する水田Fの水深に一致する高さ位置まで、上下適宜寸法毎に分割、形成した1枚または複数枚の堰板81,81,……を上方から挿し込み装着し、図4中に示すように、最下位とした高さ100mmの堰板81の一部もしくは全体が水田Fの地中に埋設状となり、最上位となる堰板81が水田Fの水面W位置を、所望する任意の水位に設定する。 One or a plurality of weir plates formed by dividing the upper and lower rails 36, 36 of the water collecting barrel 3 open and divided into appropriate dimensions in the vertical direction up to a height corresponding to the desired water depth of the paddy field F 81, 81,... Are inserted and mounted from above, and as shown in FIG. 4, a part or the whole of the bottom 100 mm of the dam plate 81 is buried in the ground of the paddy field F, The uppermost dam plate 81 sets the water surface W position of the paddy field F to a desired water level.

And the surplus weir plates 81, 81. It is possible to temporarily store and place it between the left and right storage mounting grooves 33 shown in FIG.

当該水田用水口1は、全ての堰板81,81……を、左右レール溝36,36間に装着することによって完全閉鎖し、水田F水位Wが畦Rの略全高に達したときにのみ、堰板81,81……の上端縁を乗り越えて排水されるよう設定され、最下位の堰体81のみを残すか、または全ての堰板81,81……を取り外せば、水田Fの地面が略露出されるまで排水されることとなる。     The paddy water inlet 1 is completely closed by mounting all the dams 81, 81... Between the left and right rail grooves 36, 36, and only when the paddy field F water level W reaches substantially the total height of the ridge R. The ground of the paddy field F is set so that it drains over the upper edge of the weir plates 81, 81..., Leaving only the lowermost weir body 81 or removing all the weir plates 81, 81. It will be drained until is almost exposed.

また、堰板81,81……の抜き挿し操作の際に、左右レール溝36,36に土砂等が詰まって堰板81,81……間に隙間が生じるような場合には、目詰まりを生じた堰板81,81……を一旦取り外し、各レール溝36,36の奥がわに繋がる洗浄用鉛直筒型空間37,37を通じて細い棒やブラシ等を挿し込んだり、水を供給したりすることによって簡便に排除することが可能であり、洗浄後は速やかに堰板81,81……を装着することが可能である。     In addition, if the left and right rail grooves 36, 36 are clogged with earth and sand during the insertion / removal operation of the dam plates 81, 81. The generated weir plates 81, 81... Are removed once, and thin rods, brushes, etc. are inserted through the vertical cylindrical spaces 37, 37 for cleaning, and the water is supplied. By doing so, it is possible to easily eliminate it, and it is possible to quickly attach the weir plates 81, 81.

左右隔壁板39は、図1中に示すように、背面壁31、左右内壁面部32,32、左右外壁面部34,34によって包囲された杭打ち孔21,21用の空間と、レール溝36,36の奥に繋がる洗浄用鉛直筒型空間37,37とを分離して、杭打ち孔21,21用の空間中に不要な土砂類が浸入するのを阻止すると共に、左右内壁面部32,32と左右外壁面部34,34との前端側同士を連結して集水胴部3ならびに左右呼び込み板部35,35の支持強度を高めるものとなる。     As shown in FIG. 1, the left and right partition plates 39 include a space for pile driving holes 21 and 21 surrounded by a back wall 31, left and right inner wall surface portions 32 and 32, and left and right outer wall surface portions 34 and 34, rail grooves 36, The vertical cylindrical spaces 37 and 37 for cleaning connected to the back of 36 are separated to prevent unnecessary soil and sand from entering the spaces for the pile driving holes 21 and 21, and the left and right inner wall surface portions 32 and 32. And the front end sides of the left and right outer wall surface portions 34, 34 are connected to each other to increase the support strength of the water collecting barrel portion 3 and the left and right calling plate portions 35, 35.

水田Fの収穫期を迎え、当該水田用水口1を撤去する場合には、水平翼部7を含む集水胴部3の周囲ならびに定着用前端23を掘り起こし、左右土石装填空間部6,6に充填された土石を排除した上、排水パイプBから接続用スリーブ51を外すようにして畦R土中から取り外し、水平翼部7と底板部2定着用前端23とを保持して運搬することが可能であり、全体が塩化ビニール製のため非常に軽量で持ち運びや設置および撤去作業も容易に行うことが可能であって、空洞状となった水尻畦部分Rと水田F地面とを埋め戻して撤去作業を完了することとなり、付着した土石類を十分に洗浄して保管すれば、錆や腐食等が発生しない塩化ビニール製であることから翌年以降もそのまま継続使用が可能になり、長年に渡って設置利用することができることになる。     When the harvesting season of the paddy field F is reached, when the paddy water inlet 1 is removed, the surroundings of the water collecting body 3 including the horizontal wing part 7 and the fixing front end 23 are dug up and left and right in the left and right debris loading spaces 6 and 6. After removing the filled debris, removing the connecting sleeve 51 from the drainage pipe B and removing it from the 畦 R soil, the horizontal blade 7 and the bottom plate 2 fixing front end 23 can be held and transported. It is possible to carry and install and remove easily because the whole is made of vinyl chloride, and it is possible to backfill the hollow water ridge part R and paddy field F ground. The removal work will be completed, and if the adhering debris is thoroughly washed and stored, it will be made of vinyl chloride that does not generate rust or corrosion. Can be installed and used Made to wear.

当該水田用水口1は、水田Fの排水側となる水尻畦部分Rに、開放部4を水田F側に向け、背面壁31を側溝G側に向けて埋設、設置した場合について示したが、同様の水尻畦部分Rの側溝G側に開放部4を向け、背面壁31を水田F側に向けて埋設、設置すること、または、水田F上流側となる水口畦部分の水田F側に開放部4を向け、背面壁31を側溝G側に向けて埋設、設置することや、あるいは、同水田F上流側となる水口畦部分の側溝G側に開放部4を向け、水田F側に背面壁31を向けて埋設、設置すること等、様々な設置が可能であり、さらに、開放部4から流入した用水が排水口5を通じて排水されるものとする外に、排水口5を通じて供給された用水を開放部4を通じて外部に流出させるものとするよう設置、使用することも不可能ではない。     Although the said paddy field water mouth 1 showed about the case where it was embed | buried and installed in the water bottom eaves part R used as the drainage side of the paddy field F, the opening part 4 turned to the paddy field F side, and the back wall 31 faced to the side groove G side, Place the open part 4 on the side groove G side of the same Mizushiri part R and bury and install the rear wall 31 toward the paddy field F side, or open to the paddy field F side of the paddy paddy part upstream of the paddy field F The part 4 is faced and the back wall 31 is buried and installed with the side groove G side facing, or the open part 4 is directed to the side groove G side of the waterhole basin upstream of the paddy field F and the back side to the paddy field F side. Various installations such as burying and installing the wall 31 are possible, and the water flowing in from the opening 4 is drained through the drain port 5 and supplied through the drain port 5. Install and use water so that it will flow out through the opening 4 It is not impossible.

また、図6および図7中に示したように底板部2の中央付近に鉛直状の接続用スリーブ51を形成した排水口5を設けてなる水田用水口1によれば、水田Fから隣接する側溝Gまでの高低差が大きく、鉛直状に立ち上げられた排水パイプBが設置されている水田Fに設置するのに適しており、設置および撤去、運搬作業も、前記図1ないし図6中に示したものと同等に簡便に行うことが可能であり、さらに、排水口5に図示しない円筒体(接続状態の上端縁が堰板81,81,……よりも低い)を追加して接続することによって集水胴部3内に滞留空間を形成することができ、これによって集水胴部3内に流入したゴミや草類を堰き止め、側溝Gに排出されるのを防止することが可能となる。     Moreover, according to the paddy field water inlet 1 provided with the drain port 5 in which the vertical connection sleeve 51 is formed in the vicinity of the center of the bottom plate portion 2 as shown in FIGS. The height difference to the side groove G is large, and it is suitable for installation in the paddy field F where the drainage pipe B set up vertically is installed. The installation, removal, and transportation work are also shown in FIGS. It is possible to carry out as easily as shown in Fig. 1. Furthermore, a cylindrical body (not shown) is connected to the drain port 5 (the upper edge of the connected state is lower than the weir plates 81, 81, ...).

Compared to the paddy field water inlet 1 shown in FIG. 7, it is possible to further reduce the size and weight, and as shown in FIG. 9 and FIG. In the same manner as described above, a portion corresponding to the existing or newly established drainage pipe B of the ridge R is dug up about 70 mm to 100 mm from the ground of the paddy field F, and the bottom plate portion 2 drains into the exposed drainage pipe B. The connection sleeve 51 of the mouth 5 is connected, the bottom plate portion 2 is buried so as to be placed in the paddy field F, and the left and right call-in plate portions 35, 35 on the bottom plate portion 2 are back of the debris loading space portions 6, 6, And left and right reinforcing plates 31, 3 Tamped and packed without gaps debris to multiply passed vertically I husband horizontal wings 7 people in, and that is firmly fixed.

水田Fの水深調節に際しては、図8ならびに図9中に示すように、所望の水深に底板部2の埋設深さを加えた高さ寸法に合致する排水調整部8の円筒体82の下端を、排水口5に形成された着脱用円筒枠36に嵌合状に装着し、該円筒体82の上端が設定水面Wに一致するよう設定したものとなし、設定水位Wを超えた水が、円筒体82の上端縁を乗り越え、同図9中の実線矢印に示すように、排水口5および排水パイプBを通じて側溝Gに排出されることとなり、設定水深Wを変更する場合には、予め複数準備しておいた高さ寸法の異なる複数の円筒体82,82,……の中から、所望水深に合致するものを選択して交換装着することによって調節することが可能であり、集水胴部3同等の高さの円筒体82を装着すれば全閉状態となり、畦Rの全高を超える程度の水位Wに達したときにだけ排水され、円筒体82を取り外すと着脱用円筒枠36の高さ寸法に略一致する水深まで排水されることとなり、図示していないが、該着脱用円筒枠36の上端位置を水田Fの地面と同じか、またはそれよりも低い位置に設置したときには、水田Fの地面が露出するレベルまで排水可能となる。     When adjusting the water depth of the paddy field F, as shown in FIG. 8 and FIG. 9, the lower end of the cylindrical body 82 of the drainage adjusting portion 8 that matches the height dimension obtained by adding the buried depth of the bottom plate portion 2 to the desired water depth. The cylindrical body for attachment / detachment 36 formed in the drain port 5 is fitted in a fitting manner, and the upper end of the cylindrical body 82 is set so as to coincide with the set water surface W.

実施例2の水田用水口1は、図8中に示したように、塩化ビニール管製の集水胴部3およびその開放部4を形成するために切除した円弧板材を利用して左右呼び込み板部35,35を形成したものとしたことにより、さらなる大幅な構造の簡素化と、小型、軽量化とを果たし、しかも集水胴部3に囲まれた底板部2中央に着脱用円筒枠36を有する排水口5を形成したものでは、円筒体82による排水調整部8を実現させることができ、高さ寸法の異なる円筒体82を交換するだけで水田Fの水深を簡便に調節、設定できるようになり、水田Fの水管理の作業効率とその経済性とを高めることができる上、市販の塩化ビニール管を所望の高さ寸法に切断して円筒体82を製造し、各水田Fに応じてより正確な水深管理を簡便に実現でき、さらに集水胴部3が上方に開放されており、集水胴部3内の底板部2上であって円筒体82の周囲にゴミや草、稲藁等が浸入したときにも、畦R上の作業者が手を伸ばして簡便に取り除くことができ、排水中にゴミ類が混入することを確実に防止するという秀れた特徴を発揮する。     As shown in FIG. 8, the paddy field water inlet 1 of the second embodiment uses a circular arc plate material cut out to form a water collecting body portion 3 and an open portion 4 made of a vinyl chloride pipe. Since the portions 35 and 35 are formed, the structure can be further simplified, reduced in size and weight, and the detachable cylindrical frame 36 is provided at the center of the bottom plate portion 2 surrounded by the water collecting barrel portion 3. In the case of forming the drainage port 5 having the above, the drainage adjustment unit 8 by the cylindrical body 82 can be realized, and the water depth of the paddy field F can be easily adjusted and set only by exchanging the cylindrical body 82 having different height dimensions. Thus, the water management work efficiency of paddy field F and its economic efficiency can be improved, and a commercially available vinyl chloride tube is cut to a desired height to produce a cylindrical body 82. In response, more accurate water depth management can be easily achieved. Even when dust, grass, rice straw, etc. enter the periphery of the cylindrical body 82 on the bottom plate part 2 in the water collecting body 3 and the water collecting body 3 is opened upward, Can be easily removed by extending the hand, and exhibits an excellent feature of reliably preventing the entry of garbage into the drainage.

It can be mounted in the form of an excellent attachment and detachment work, and can be firmly fixed to prevent the occurrence of harmful effects such as runoff, and in the installed state, the center of the side groove G of the water collecting barrel 3 The slanted derivative 9 is integrated with the front wall that is closer to the wall, and the suspended matter such as dust, grass, and rice straw flowing down the gutter G is raised to the vicinity of the water surface by the slanted surface wall 91 of the slanted derivative 9 and cannot be blocked by the sluice S. Thus, it is guided to flow smoothly downstream, and an effect that dust and grass can be prevented from flowing into the water collecting barrel 3 through the drainage adjusting unit 8 can be expected.

また、集水胴部3の底部を底板部2によって閉鎖し、傾斜誘導体9の傾斜面壁91の下側を周面壁92で包囲したものでは、側溝Gを流下する水流を安定的に整流可能とし、乱流等の発生を阻止すると共に、当該傾斜面壁91が水流の圧力を受けて側溝G底面に押し付けられるものとなって水量が多いほど定着力が高まり、水田用水口1自体の破損や離脱、流失等の発生を防止できるという利点が得られる。     In addition, in the case where the bottom portion of the water collecting barrel 3 is closed by the bottom plate portion 2 and the lower side of the inclined wall 91 of the inclined derivative 9 is surrounded by the peripheral wall 92, the water flow flowing down the side groove G can be stably rectified. In addition to preventing the occurrence of turbulent flow, the inclined wall 91 is pressed against the bottom surface of the side groove G by receiving the pressure of the water flow, and the fixing power increases as the amount of water increases, and the paddy mouth 1 itself is damaged or detached. The advantage of preventing the occurrence of loss or the like can be obtained.
