Description

【０００１】
【発明の属する技術分野】
本発明は、畜舎や鶏舎に吊り支持され、畜舎内や鶏舎内を送風する農事用大型送風機に関するものである。
【０００２】
【従来の技術】
畜舎内や鶏舎内の環境保全のために使われる農事用大型送風機は、外径が１ｍにも及ぶ大型のものであり、畜舎や鶏舎の天井等に吊り固定されることが多い。この種の従来の農事用大型送風機は、モーターがリング形の風洞の中心上に数本の取付脚によって支持され、モーターの回転軸に風洞内で回転する羽根車が装着され構成である。風洞は、亜鉛メッキ鋼板で作られ、ベルマウス状の曲面構成となっている。羽根車は、プロペラファンで、ステンレスや溶融亜鉛メッキの鋼板で作られている。
【０００３】
【発明が解決しようとする課題】
上記した従来の農事用大型送風機においては、据付けや取外し時にはどうしても鋼板製の風洞に手を掛けて扱わねばならず、握り締めることが出来ない構造であるため、持運びや取扱いが大変し辛いものである。
【０００４】
本発明は、係る従来の問題点を解決するためになされたものであって、その課題とするところは、持運びや取扱いが容易な農事用大型送風機を得ることであり、その農事用大型送風機の製造コストの低減を推進することである。
【０００５】
【課題を解決するための手段】
前記課題を達成するために請求項１の発明は、モーターが風洞の中心線上に数本の取付脚によって支持され、そのモーターの回転軸に風洞内で回転する羽根車が装着された農事用大型送風機について、その風洞を棒状材で構成する手段を採用する。
【０００６】
前記課題を達成するために請求項２の発明は、請求項１に係る前記手段における風洞をパイプ材で構成する手段を採用する。
【０００７】
前記課題を達成するために請求項３の発明は、請求項１又は請求項２のいずれかに係る前記手段における風洞を円形断面の材料で構成する手段を採用する。
【０００８】
前記課題を達成するために請求項４の発明は、請求項１〜請求項３までのいずれかに係る前記手段における取付脚と風洞とを金具で結合し、金具を、取付脚を固定するフランジと、風洞を半径方向から挟持する挟持部から構成する手段を採用する。
【０００９】
【発明の実施の形態】
図１及び図２によって示す本実施の形態は、畜舎や鶏舎に鎖等で吊り支持され、畜舎内や鶏舎内を送風する外径が１ｍ程度の農事用大型送風機に関するものである。この農事用大型送風機は、図１に示すように、モーター１が風洞２の中心線上に数本の取付脚３によって支持され、そのモーター１の回転軸に風洞２内で回転するプロペラファンによる羽根車４が装着されている。風洞２は、円形断面の鋼パイプを円形に曲げて構成されている。取付脚３は、モーター取付板５に二本の曲げパイプを、略Ｘ字状に四本の脚部が延出するようにネジ付けされて構成されている。
【００１０】
取付脚３の四本の脚部の自由端側と、風洞２とは図２に示すような連結金具６で固定されていている。モーター１は、モーター取付板３にその外殻のフランジにおいて回転軸が風洞２の中心線に沿うようにネジ固定され、その回転軸に羽根車４が風洞２内で回転するように装着されている。連結金具６は、ウエブ部７の一方に取付脚３の自由端側を固定するフランジ８が設けられ、ウエブ部７の他方に風洞２を半径方向から挟持する挟持部９が設けられている。挟持部９は、ウエブ部７の一部とフランジ１０と立上り部１１とによりチャンネル状に構成され、チャンネル部に風洞２を入れ、ウエブ部７と立上り部１１間をネジ締めすることによって風洞２を挟持する。挟持部９に対向するフランジ８には、各脚部の自由端側が当沿わされネジ付けにより固定されている。四個の連結金具６の一つは、その挟持部９によって風洞２の端面同士の突合せ部を挟持するよう二本のネジによって締め固定されている。
【００１１】
この連結金具６の採用により、風洞２を突合せ部で溶接するような手間もかからず、風洞２の周上を自由に移動させ得るため、脚部との位置関係が拘束されることもなく、大径の風洞２に正確にネジ孔を開ける必要もなく製造コストの低減を推進できる。
【００１２】
この農事用大型送風機においては、風洞２が握り易いパイプ材であるため、取付けや取外し、或いは持運びといった扱いにおいて風洞２を握り持って行うことができ、大型であっても扱い易いものとなる。送風性能に関しても、風洞２のプロフィルがベルマウスの一部と類似形状となっているため、性能低下はきたさない。
【００１３】
なお、風洞２を単に棒状材で構成しても、握り易さが備わり、大型であっても扱い易い農事用大型送風機となる。また、風洞２を、アルミ板材等をバーリング加工により円形断面のバイブ状にしたもので構成してもよい。さらに、連結金具６の挟持部９については、一体構造でなくても挟持片をウエブ部７に両端においてネジ締めする構造を採ることもできる。
【００１４】
【発明の効果】
請求項１の発明によれば、持運びや取扱いが容易な農事用大型送風機が得られる。
【００１５】
請求項２の発明によれば、持運びや取扱いが容易な農事用大型送風機を得る持運びや取扱いが容易な農事用大型送風機が得られる。
