Description

耕水機Cultivator
本発明は、種々ある形状の養殖池に容易に対応でき、また、長期的に使用が可能な耕水機に関する。 The present invention relates to a water cultivator that can easily cope with a variety of shapes of aquaculture ponds and can be used for a long time.
　一般的に、魚介類の養殖池は、自然界と同様の環境を魚介類に提供するべく、養殖池全域に対して、常に養殖水を撹拌し、酸素を供給して水中溶存酸素量を増加させ、また、水流を起こして水温やＰＨ値を一定に維持する必要がある。そのため、従来、養殖水を撹拌するために、モータ駆動の水車型エアレーションが利用されている。 In general, aquaculture ponds for seafood increase the amount of dissolved oxygen in the water by constantly agitating the aquaculture water and supplying oxygen to the entire aquaculture pond in order to provide seafood with the same environment as the natural world. Also, it is necessary to maintain a constant water temperature and pH value by causing a water flow. Therefore, conventionally, motor-driven water wheel aeration has been used to agitate the aquaculture water.
　しかしながら、当該水車は、回転方向が水面に対して直角であり、養殖水を攪拌する量が少なく、かつ、養殖水に対して水平・垂直方向ともに水流の及ぶ範囲が狭いために、養殖池全域に酸素を供給するのが困難である。さらに、養殖池の底にまで水流を発生させることができないため、エサの残骸や糞等のヘドロが水底に堆積して養殖池の環境を汚染させるという問題があった。また、稼働による電力消費が大きいことから電力事情の悪い国や地域では利用が困難である。これらの問題は、養殖事業において、運営費用の増加や汚染養殖池の利用不能等、事業存続において著しい問題となっていた。このような問題に対し、以下のような耕水機が提供されている。 However, the rotation direction of the water turbine is perpendicular to the water surface, the amount of agitation of the aquaculture water is small, and the range of the water flow is narrow in both the horizontal and vertical directions with respect to the aquaculture water. It is difficult to supply oxygen. Furthermore, since a water flow cannot be generated to the bottom of the culture pond, sludge such as food debris and feces accumulates on the bottom of the water and contaminates the environment of the culture pond. In addition, since power consumption due to operation is large, it is difficult to use in countries and regions where power conditions are poor. These problems have become serious problems in the survival of the aquaculture business, such as an increase in operating costs and the inability to use contaminated aquaculture ponds. The following cultivators are provided for such problems.
　浮力を有して放射方向に配した複数の回転アームを具え、当該各回転アームの先端下部に夫々下方に羽根板が垂設されて、養殖池の水面に前記回転アームを水平回転可能に配置した耕水機が提供されている（特許文献１）。当該耕水機によれば、当該回転アームに従って回転する羽根板が水面近傍の養殖水を外側に掻き出す作用で当該回転アーム下方の養殖水を上方に吸い上げることができ、養殖池の養殖水に対流を起こすことができる。 It has a plurality of rotating arms that have buoyancy and are arranged in the radial direction, and blades are hanged downward at the lower end of each rotating arm so that the rotating arm can be rotated horizontally on the water surface of the aquaculture pond. An improved water cultivator is provided (Patent Document 1). According to the cultivator, the slats rotating according to the rotating arm scoop out the aquaculture water near the surface of the water, and can suck up the aquaculture water below the rotating arm and convect the aquaculture water in the aquaculture pond. Can be caused.
特開２０１０－８８３１５号公報JP 2010-88315 A
　しかしながら、一般的に、養殖池の平面視形状は、特許文献１で図示されているような円形のみならず、正方形や長方形、台形等の形状で構築されたものもあり、また、天然池のようにいびつな形状のものも存在する。また、魚介類の養殖は、常に同じ養殖池で行われることはほとんどなく、通常、種々ある魚介類の魚種や水揚げ量等に応じて養殖池を変更して行われる。これに対し、特許文献１に記載の耕水機は、回転アームの直径が固定され、かつ、羽根板の設置箇所も固定されているため、養殖水の掻き出し及び汲み上げに関し、種々ある養殖池の形状に適して対流を起こすことはできない。そのため、当該従来の耕水機では、各養殖池に適合するように、回転アームの長さや羽根板の設置箇所が異なる耕水機を個別に製造しなければならず、製造コストが増大して耕水機の普及を阻害しているという問題があった。 However, in general, the shape of the aquaculture pond in plan view is not only a circular shape as illustrated in Patent Document 1, but also a shape such as a square, a rectangle, or a trapezoid. There are also distorted shapes. In addition, seafood culture is rarely performed in the same culture pond at all times, and is usually performed by changing the culture pond according to the fish species of various seafood and the amount of landing. On the other hand, since the diameter of the rotary arm is fixed and the installation location of the slats is also fixed, the water cultivator described in Patent Document 1 has various aquaculture ponds for raking out and pumping the aquaculture water. Convection cannot occur to suit the shape. Therefore, in the conventional water cultivator, the water cultivator having different lengths of the rotating arms and the installation positions of the blades must be individually manufactured so as to be adapted to each aquaculture pond. There was a problem that the spread of cultivators was hindered.
　また、一方で、当該従来の耕水機は、回転アームの直径が固定され、かつ、羽根板の設置箇所も固定されているために、種々ある養殖池の形状に応じて水面への設置位置を変更したり、前述のように耕水機の設計を変更したりする必要がある。そのため、当該従来の耕水機は、各養殖池に合わせて効率的に対流を起こすために、研究者又は技術者等の専門家の意見を手間を掛けて確認しなければならず、最適な対流を容易に起こすことができないという問題があった。 On the other hand, since the conventional tiller has a fixed diameter of the rotary arm and a fixed location of the slats, the installation position on the water surface depends on the shape of various aquaculture ponds. It is necessary to change the design of the tiller as described above. For this reason, the conventional tillage machine has to check the opinions of experts such as researchers or engineers in order to efficiently generate convection according to each aquaculture pond. There was a problem that convection could not be easily caused.
　さらに、当該従来のような耕水機に係る羽根板は、当該羽根板の強度の向上及び海水又は汽水への対塩効果を目的として、対塩性に優れたステンレスが素材として採用されるのが一般的である。一方、このような当該ステンレスの対塩効果は、ステンレス中に含まれる成分が酸素と結合して皮膜を生成することによって達成されるものである。しかしながら、当該羽根板は、養殖池の海水又は汽水等の塩水中に常時浸水して動作するものであるため、通常、酸素に触れることは一切ない。そのため、当該ステンレス製の羽根板は、比較的強度の弱い回転アームとの接合箇所を含めて、使用開始から約３ヶ月から１年以内に欠損することもある。したがって、当該羽根板は、長期的に使用することができず、短期間で交換する必要もあるために、運用コストが増大するといった問題が生じていた。 Furthermore, for the blades according to the conventional tillage machine, stainless steel having excellent salt resistance is adopted as a material for the purpose of improving the strength of the blades and salting effect on seawater or brackish water. Is common. On the other hand, such a salt effect of the stainless steel is achieved by the formation of a film by combining the components contained in the stainless steel with oxygen. However, the slats are normally immersed in salt water such as seawater or brackish water in an aquaculture pond, so that they usually do not come into contact with oxygen. For this reason, the stainless steel slat may be lost within about 3 months to 1 year from the start of use, including the joint portion with the relatively weak rotating arm. Therefore, the vane plate cannot be used for a long period of time and needs to be replaced in a short period of time, resulting in a problem that the operation cost increases.
　そこで、本発明は、容易に種々ある形状の養殖池に対応でき、また、長期的に使用が可能な耕水機を提供することを課題とした。 Therefore, an object of the present invention is to provide a water cultivator that can easily cope with various types of aquaculture ponds and can be used for a long time.
　上記課題を解決するために、本発明は次のように構成した。すなわち、本発明に係る耕水機は、駆動装置と、前記駆動装置に軸支された回転軸と、前記回転軸により水面で水平回転可能に設けられた回転アームと、前記回転アームから下方に突設した水掻き板とからなる耕水機であって、前記水掻き板の上部を挟み込む挟持部が前記回転アームの下部に設けられ、前記水掻き板は、耐塩水性素材で形成され、かつ、当該水掻き板の上部が前記挟持部に挟み込まれて、当該水掻き板の両側面から固定可能に形成されていることを特徴としている。 In order to solve the above problems, the present invention is configured as follows. That is, the cultivator according to the present invention includes a driving device, a rotating shaft that is pivotally supported by the driving device, a rotating arm that is horizontally rotatable on the water surface by the rotating shaft, and a downward direction from the rotating arm. A cultivator comprising a protruding watering board, wherein a sandwiching part for sandwiching an upper part of the watering board is provided at a lower part of the rotating arm, and the watering board is formed of a salt water-resistant material, and the watering board The upper part of the board is sandwiched between the clamping parts and is formed so as to be fixable from both side surfaces of the watering board.
　また、当該耕水機は、前記挟持部が前記回転アームの下面から上方に切欠いた長手方向の溝部により、当該溝部両側の回転アームの一部を挟持部として形成してなることを特徴している。 Further, the cultivator is characterized in that a part of the rotating arm on both sides of the groove part is formed as a sandwiching part by a longitudinal groove part in which the sandwiching part is notched upward from the lower surface of the rotating arm. Yes.
　また、当該耕水機は、前記水掻き板が前記挟持部に摺動自在に挟み込まれ、所定位置で固定可能に突設されていることを特徴としている。 Also, the water cultivator is characterized in that the water scraper is slidably inserted into the holding portion and protruded so as to be fixed at a predetermined position.
　また、当該耕水機は、前記挟持部間で水掻き板を摺動自在に挟み込んだ耕水機において、前記水掻き板が当該水掻き板の側面で上部の前記挟持部へ挟み込んだ面を除く露出面に目印が表示されており、かつ、前記回転アームが当該回転アームの側面に一定間隔で目盛りが表示されていることを特徴としている。 Further, in the water tiller in which the water scraper is slidably sandwiched between the sandwiching portions, the exposed surface excluding the surface in which the water scraper is sandwiched by the side of the water scraper into the upper sandwiching portion. In addition, a mark is displayed on the rotating arm, and a scale is displayed on the side surface of the rotating arm at regular intervals.
　さらに、当該耕水機は、前記水掻き板が、当該板状の上下幅において、前記回転軸方向の内側が幅広で外側が幅狭の二段の幅で形成されていることも特徴としている。 Further, the water tiller is characterized in that the watering board is formed in a two-stage width in which the inner side in the rotation axis direction is wide and the outer side is narrow in the plate-like vertical width.
　本発明に係る耕水機によれば、前記水掻き板を耐塩水性素材で形成したことにより、長期的に海水又は汽水等の塩水中でも使用することができる。一方で、当該耐塩水性素材は、従来のステンレスに比べて強度が低く、また、ステンレスよりも回転アームへの接合が難しいという問題もある。そこで、本発明に係る耕水機は、当該耐塩水性素材の水掻き板を回転アーム下方に設けた挟持部に挟み込んで水掻き板の両側面から固定して固定面積を広げることにより、回転アームの回転による水抵抗に耐え得る強度を容易に得ることができ、短期間で欠損することなく長期的に使用することができる。 The cultivator according to the present invention can be used in salt water such as seawater or brackish water for a long time by forming the water scraper with a salt water-resistant material. On the other hand, the salt water resistant material has a problem that the strength is lower than that of conventional stainless steel, and it is more difficult to join the rotating arm than stainless steel. Therefore, the tiller according to the present invention is configured to rotate the rotating arm by expanding the fixed area by sandwiching the salt water resistant material scraping board between the holding parts provided below the rotating arm and fixing it from both sides of the scraping board. Therefore, it is possible to easily obtain a strength capable of withstanding water resistance, and to use it for a long time without being lost in a short period of time.
　また、前記回転アームの下部に長手方向の溝部を設けた耕水機によれば、回転アームの下部から他の部材を接合する等して改めて挟持部を設ける必要がなく、既存の回転アームの下部に経済的に挟持部を形成することができる。また、他の部材を用いて回転アームの下部に挟持部を設けるのに比べ、接合箇所を減らすことができるため、優れた強度を保持することができる。 Further, according to the cultivator provided with a longitudinal groove in the lower part of the rotating arm, there is no need to provide a clamping part by joining another member from the lower part of the rotating arm, etc. A clamping part can be formed economically in the lower part. Moreover, compared with providing a clamping part in the lower part of a rotation arm using another member, since a joining location can be reduced, the outstanding intensity | strength can be hold | maintained.
　また、前記水掻き板を前記挟持部に摺動自在に挟み込んだ耕水機によれば、種々ある形状の養殖池に対応させて水掻き板の固定位置を変更することにより、各養殖池に適合した最適な対流を起こすことができる。また、耕水機の構成を種々ある形状の養殖池に合わせて設計変更する必要がなく、耕水機の構成部品等を統一することができるため、製造コストを減少させることができる。このように、当該耕水機は、前記水掻き板を挟み込むことにより、水掻き板の挟持による強度の向上と摺動による養殖池の対流の最適化という効果を同時に得ることができる。 Moreover, according to the cultivator in which the watering plate is slidably sandwiched in the holding part, the watering plate is adapted to each culture pond by changing the fixing position of the watering plate corresponding to the culture pond of various shapes. Optimum convection can occur. Moreover, it is not necessary to change the design of the structure of the water cultivator according to the culture ponds of various shapes, and the components of the water cultivator can be unified, so that the manufacturing cost can be reduced. Thus, the water cultivator can obtain the effects of improving the strength by sandwiching the water scraper and optimizing the convection of the culture pond by sliding by sandwiching the water scraper.
　また、前記回転アーム及び水掻き板に夫々目印及び目盛りを表示した耕水機によれば、改めて専門家の意見を確認することなく、目印と目盛りに関するマニュアルを参照するようにし、水掻き板の目印を回転アームの目盛りに合わせることで、誰でも容易に水掻き板の固定位置を適切に変更することができるようになる。 In addition, according to the cultivator with the marks and scales displayed on the rotary arm and the water scraper, respectively, without referring to the expert's opinion again, the manual on the marks and scales is referred to and the marks on the water scraper are marked. By adjusting to the scale of the rotating arm, anyone can easily change the fixing position of the water scraper appropriately.
　さらに、前記水掻き板を前記回転軸方向の内側が幅広で外側が幅狭の二段の幅で形成した耕水機によれば、幅広く形成した部分が多くの養殖水を外方向に掻き出す分、下方の養殖水を多く汲み上げることができ、一方で、幅狭く形成した部分が、前記汲み上げられた養殖水を無駄なく水面近傍で外方向に掻き出して、より遠方に、かつ、より空気中の酸素が養殖水に混ざるように、効果的に対流を起こすことができる。当該形状の水掻き板であれば、水掻き板の固定位置を養殖池の形状に合わせて変更すれば、より最適に養殖水の対流を起こすことができ、本発明に係る耕水機にとって、最適な形状の水掻き板である。 Furthermore, according to the water cultivator formed with the two-stage width of the water scraper plate with the inner side in the rotation axis direction being wide and the outer side being narrow, the widely formed part scrapes a lot of aquaculture water outward, A large amount of aquaculture water below can be pumped up. On the other hand, the narrowly formed portion scrapes the pumped-up culture water outward in the vicinity of the water surface without waste, so that oxygen in the air is further distant. Can effectively cause convection to mix with the aquaculture water. If it is the watering board of the said shape, if the fixing position of the watering board is changed according to the shape of the culture pond, the convection of the aquaculture water can be caused more optimally, which is optimal for the water cultivator according to the present invention. It is a shaped water scraper.

　以下、図面に基づいて本発明を具体的に説明する。まず、本発明に係る第１実施例の耕水機について、図１乃至図５を用いて説明する。図１は、本発明に係る耕水機１の構成を示す斜視図であり、図２は、当該耕水機１の構成を示す側面図である。当該耕水機１は、モータ等の駆動装置２と、当該駆動装置２に軸支された回転軸３と、前記駆動装置２から前記回転軸３を介して回転運動が伝達されて水面で水平回転運動を行い、フロート機能を有する複数の回転アーム４と、当該回転アーム４から下方に突設された水掻き板５とから構成される。 Hereinafter, the present invention will be specifically described with reference to the drawings. First, the tiller of the first embodiment according to the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 is a perspective view showing the configuration of the tiller 1 according to the present invention, and FIG. 2 is a side view showing the configuration of the tiller 1. The cultivator 1 has a driving device 2 such as a motor, a rotating shaft 3 pivotally supported by the driving device 2, and a rotational motion transmitted from the driving device 2 through the rotating shaft 3 so that the water cultivator 1 is horizontal on the water surface. It comprises a plurality of rotating arms 4 that perform a rotational movement and have a float function, and a water scraper 5 that projects downward from the rotating arms 4.
　前記駆動装置２及び回転軸３について、詳細には図示せず概略的にのみ示すが、当該駆動装置２による回転運動が前記回転軸３に伝達され、当該回転軸３の回転運動により前記回転アーム４が水平回転運動するように構成できれば、どのような構成であってもよい。また、当該耕水機１は、前記回転軸３の下方にフロート６を具えており、前記回転アーム４のフロート機能が補助されている。 The driving device 2 and the rotating shaft 3 are not shown in detail in detail, but only schematically, but the rotating motion by the driving device 2 is transmitted to the rotating shaft 3, and the rotating arm 3 is rotated by the rotating motion of the rotating shaft 3. Any configuration may be used as long as 4 can be configured to rotate horizontally. Moreover, the said water cultivator 1 is provided with the float 6 under the said rotating shaft 3, and the float function of the said rotating arm 4 is assisted.
　また、図２中に示した矢印は、養殖水の対流を示すものである。当該養殖水の対流は、当該水掻き板５を下部に備えた回転アーム４が水平回転運動を行うと、水掻き板５によって養殖水が外側水平方向に掻き出され、それに伴い、当該外側に掻き出された養殖水の分、当該耕水機１の下方の養殖水が汲み上げられることによって生じる。 In addition, the arrows shown in FIG. 2 indicate the convection of the aquaculture water. The convection of the aquaculture water is that the aquaculture water is scraped out by the scooping plate 5 in the horizontal direction when the rotating arm 4 provided with the scooping plate 5 at the bottom performs a horizontal rotational movement, and accordingly, the scooping water is scraped to the outside. This is caused by pumping up the aquaculture water below the cultivator 1 by the amount of the aquaculture water.
　図３は、当該耕水機１の回転アーム４及び水掻き板５を示す図であり、図４は、当該耕水機１の回転アーム４及び水掻き板５を示すＡ－Ａ断面図である。当該回転アーム４は、前述の通り、フロート機能を有する。そのため、耕水機１を養殖池に設置した際には、当該回転アーム４の下方が水面に接するように配される。 FIG. 3 is a view showing the rotating arm 4 and the watering board 5 of the water cultivator 1, and FIG. 4 is an AA sectional view showing the rotating arm 4 and the watering board 5 of the water cultivator 1. As described above, the rotating arm 4 has a float function. Therefore, when the water cultivator 1 is installed in the aquaculture pond, it is arranged so that the lower side of the rotating arm 4 is in contact with the water surface.
　また、当該回転アーム４は、下面から上方に切欠いた溝部４１が回転アーム４の長手方向に設けられている。これにより、当該溝部４１の両側面側の回転アーム４を前記水掻き板５を挟み込む挟持部４２として夫々形成することができる。本第１実施例において、当該溝部４１は、回転アーム４の外側先端から中央近傍までの長さで形成されている。また、前記水掻き板５は、挟持部４２間を回転アーム４の長さ方向に自由に摺動させることができ、所定の位置で固定することができるように形成されている。 Further, the rotary arm 4 is provided with a groove portion 41 notched upward from the lower surface in the longitudinal direction of the rotary arm 4. Thereby, the rotating arms 4 on both side surfaces of the groove portion 41 can be formed as sandwiching portions 42 for sandwiching the water scraper plate 5, respectively. In the first embodiment, the groove 41 is formed with a length from the outer tip of the rotating arm 4 to the vicinity of the center. Further, the water scraper 5 is formed so as to be freely slidable in the length direction of the rotary arm 4 between the clamping portions 42 and to be fixed at a predetermined position.
　なお、回転アーム４の長さは、前記モータ等の駆動装置２の出力に応じて、当該回転アーム４を回転させることのできる最大の長さで形成されるのが好ましい。そして、当該駆動装置２の出力に応じた長さの回転アーム４において、前記挟持部４２を回転アーム４の外側先端から中央近傍まで設けることにより、前記水掻き板５は、前記駆動装置２の出力に応じた最大幅で摺動自在となり、水掻き板５の摺動可能な幅を大きく広げることができる。 In addition, it is preferable that the length of the rotating arm 4 is formed with the maximum length that can rotate the rotating arm 4 according to the output of the driving device 2 such as the motor. Then, in the rotating arm 4 having a length corresponding to the output of the driving device 2, the gripping portion 42 is provided from the outer end of the rotating arm 4 to the vicinity of the center, so that the water scraper plate 5 can output the output of the driving device 2. It becomes slidable with the maximum width according to the slidable width of the water wetting plate 5 can be greatly widened.
　前記水掻き板５は、繊維強化プラスチック（ＦＲＰ）やポリプロピレン、エンジニアリングプラスティック等といった対塩水性素材により形成されている。これにより、当該水掻き板５は、養殖池の海水や汽水等の塩水に常時浸水しても、当該塩水による腐食を防止することができ、長期的に使用することができる。また、当該耐塩水性素材の水掻き板５の強度は、前記挟持部４２を用いて両側面から当該水掻き板５を挟み込んで固定することにより、固定面積を大きくすることができ、水中での回転による抵抗に耐え得る強度に向上させることができる。 The water scraper 5 is made of a salt-water-resistant material such as fiber reinforced plastic (FRP), polypropylene, engineering plastic or the like. Thereby, even if the said watering board 5 is always immersed in salt water, such as seawater of a culture pond and brackish water, the corrosion by the said salt water can be prevented and it can be used for a long term. Further, the strength of the water-scraping plate 5 of the salt water-resistant material can be increased by sandwiching and fixing the water-scraping plate 5 from both side surfaces by using the clamping part 42, and by rotating in water. It is possible to improve the strength to withstand resistance.
　また、前記水掻き板５は、当該板状の上下幅において、前記回転軸方向の内側を幅広く、外側を幅狭く形成されている。当該形状の水掻き板５によれば、幅広く形成した部分が多くの養殖水を外方向に掻き出す分、下方の養殖水を多く汲み上げることができ、一方で、幅狭く形成した部分が、前記汲み上げられた養殖水を無駄なく水面近傍で外方向に掻き出して、より遠方に、かつ、より空気中の酸素が養殖水に混ざるように、効率的に対流を起こすことができる。このように形成した水掻き板５は、養殖水の汲み上げ及び掻き出す位置を養殖池の形状に合わせて適切に配置することにより、さらに効率的な対流を起こすことが可能となるため、当該水掻き板５の固定位置を変更できる本発明に係る耕水機１にとっては、最適の形状である。なお、前記水掻き板５は、当該水掻き板５の下端に、養殖水の汲み上げ効果を向上させることを目的として、水掻き片５１が形成されている。 Further, the web 5 is formed so that the inner side in the direction of the rotation axis is wide and the outer side is narrow in the plate-like vertical width. According to the water scraping plate 5 of the shape, the portion formed widely can scoop out a large amount of aquaculture water, so that a large amount of aquaculture water below can be pumped up, while the portion formed narrowly is pumped up. The cultivated water is scraped outward in the vicinity of the water surface without waste, and convection can be efficiently caused so that the oxygen in the air is mixed with the cultured water further away. The water scraper 5 formed in this way can cause more efficient convection by appropriately arranging the pumping up and scraping positions of the culture water in accordance with the shape of the culture pond. Therefore, the water scraper 5 It is an optimal shape for the cultivator 1 according to the present invention that can change the fixed position. The water scraper 5 is formed with a water scraping piece 51 at the lower end of the water scraper 5 for the purpose of improving the pumping effect of the aquaculture water.
　前述の通り挟み込まれた水掻き板５は、固定具７によって固定される。当該固定具６は、チタン等の対塩性素材で形成されている。図４に示すように、当該水掻き板５は、棒状のボルト７１を図示しない水掻き板５の上部に設けた孔を介して前記貫通孔４３に挿通させ、ナット７２で螺合して固定されている。なお、当該水掻き板５の固定手段は、当該実施例で示したものに限られず、当該水掻き板５の上部を挟み込むようにして固定できればどのような手段であってもよい。このように、当該水掻き板５は、当該固定具７によって堅固に両側面から固定されるために、強度の向上のみならず、接合箇所における強度の低下という問題をも解消することができる。 The web 5 sandwiched as described above is fixed by the fixture 7. The fixture 6 is made of a salt-resistant material such as titanium. As shown in FIG. 4, the water scraping plate 5 is inserted into the through hole 43 through a hole provided in the upper portion of the water scraping plate 5 (not shown), and is screwed and fixed with a nut 72. Yes. In addition, the fixing means of the said watering board 5 is not restricted to what was shown in the said Example, What kind of means may be used if it can fix so that the upper part of the said watering board 5 may be inserted | pinched. Thus, since the said watering board 5 is firmly fixed from the both sides by the said fixing tool 7, not only the improvement of an intensity | strength but the problem of the fall of the intensity | strength in a joining location can also be eliminated.
　図５は、前記水掻き板５の摺動の様子を示す図である。当該水掻き板５は、挟持部４２間の溝部４１に嵌め込まれて、前記回転アーム４の長手方向に沿って摺動させ、任意の箇所で前記固定具７により固定することができる。 FIG. 5 is a diagram showing the sliding state of the water scraper 5. The web 5 can be fitted into the groove 41 between the clamping parts 42 and slid along the longitudinal direction of the rotary arm 4 and can be fixed by the fixing tool 7 at an arbitrary position.
　このように、当該水掻き板５を前記挟持部４２間で摺動自在に形成したことにより、当該耕水機１は、種々ある形状の養殖池に対応させて水掻き板５の固定位置を変更し、各養殖池に適合した適切に対流を起こすことができるようになる。 Thus, by forming the water scraper 5 so as to be slidable between the sandwiching portions 42, the water cultivator 1 changes the fixing position of the water scraper 5 in correspondence with the culture ponds having various shapes. It will be possible to generate convection appropriately suitable for each aquaculture pond.
　また、種々ある形状の養殖池ごとに耕水機１の形状を設計する必要がないため、耕水機１の構成部品等を統一することができ、当該耕水機１の製造コストを減少させることができる。 Moreover, since it is not necessary to design the shape of the cultivator 1 for each culture pond having various shapes, the components of the cultivator 1 can be unified, and the manufacturing cost of the cultivator 1 is reduced. be able to.
　さらに、当該耕水機１は、前記水掻き板５の上部を前記溝部４１に挿入して挟み込むことにより、耐塩水性素材の水掻き板５の挟持による強度の向上と、摺動による養殖池の対流の最適化という効果を同時に得ることができる。 Further, the cultivator 1 inserts the upper part of the water scraper plate 5 into the groove 41 and sandwiches it, thereby improving the strength of the salt water resistant material water scraper plate 5 and the convection of the culture pond by sliding. The effect of optimization can be obtained at the same time.
　このような水掻き板５の摺動に対応して、前記各図に示すように、前記回転アームの側面に目盛り４４と、前記水掻き板５の露出した側面に目印５２が設けられている。当該耕水機１による養殖水への酸素供給機能を正しく発揮させるためには、当該耕水機１による酸素供給面積を正しく理解し、各養殖池によって最適に当該耕水機１を配置する必要がある。そのため、当該目盛り４４及び目印５２に対応して、水掻き板５の最適な固定位置をマニュアル化すれば、研究者又は技術者等の専門家の意見を改めて確認することなく、当該水掻き板５を摺動して固定位置を適切かつ容易に変更し、当該耕水機１を種々形状の異なる各養殖池に対して最適に配置することができる。 Corresponding to such sliding of the water scraper 5, as shown in the respective drawings, a scale 44 is provided on the side surface of the rotating arm, and a mark 52 is provided on the exposed side surface of the water scraper 5. In order to correctly demonstrate the oxygen supply function to the aquaculture water by the cultivator 1, it is necessary to correctly understand the oxygen supply area by the cultivator 1 and to arrange the cultivator 1 optimally for each culture pond. There is. Therefore, if the optimum fixing position of the water scraper 5 is made manual corresponding to the scale 44 and the mark 52, the water scraper 5 can be removed without reconfirming the opinions of experts such as researchers or engineers. The fixed position can be changed appropriately and easily by sliding, and the cultivator 1 can be optimally arranged for each culture pond having different shapes.
