【発明の属する技術分野】
本発明は、走行しながら融雪する自走型の融雪装置に関する。
【0002】
【従来の技術】
従来技術の融雪装置の構成として、積雪を掻き取り、雪片化して放出するための回転羽根駆動部を台車枠の前部に、燃焼ガスを発生する燃焼装置を台車枠の後部に備え、前記回転羽根駆動部と前記燃焼装置との間に融雪板を配置し燃焼ガスにより融雪板を加熱し、前記回転羽根駆動部により放出された雪片を融雪板に直接接触させ融雪するものが公知である。(特許文献1)
【0003】
又、移動車体と、この移動車体の前下部に設けられた雪かき体と、この雪かき体の上方部に設けられ内壁部に多数の熱風吹出孔を有し、かつ前記雪かき体から雪を取り入れる揚上装置を備えた消雪ルームと、前記移動車体上に設けられ、かつ前記消雪ルームに接続され、前記多数の熱風吹出孔から熱風を吹き出させる熱風発生装置とを具備し、移動車体を前進させ雪かき体上に雪が移載されるとともにこの雪は揚上装置にて消雪ルーム内に順次供給し、消雪ルーム内には熱風が噴出されているので、その熱によって消雪ルーム内に供給される雪を順次融雪するものも公知である。(特許文献2)

【発明が解決とようとする課題】
前記従来技術において、雪片を加熱した融雪板に直接接触させ融雪する構成では、雪片が融雪板に接触する度に融雪板が冷却され、融雪板の温度を一定に保つことができず融雪効率が低下し、作業スピードが遅くなるという課題がある。
【0006】
又、雪かき体上の雪を揚上装置にて揚上させ、消雪ルーム内に噴出する熱風で融雪する構成では、圧雪や氷となった雪が解けにくく、消雪ルームの上部に溜まり雪詰まりの原因となり、その都度取り除かなければならないため作業効率が低下するという課題があった。
【0007】
そこで本発明は、融雪効率の向上を計り、あらゆる雪質に対しても安定し、スムーズな融雪作業を行える自走型の融雪装置を提供することを目的とする。
【0008】
【課題を解決するための手段】
前記した課題を解決するため、走行可能とした台車と、台車の前方部に配置したオーガハウジングと、台車上に載置された熱風発生装置とから構成され、この熱風発生装置より吹出された熱風にて融雪する自走型融雪装置において、オーガハウジングは前方に開口部を有した箱体で、内部には前方に掻き込みオーガと後方に粉砕オーガを進行方向に対し直交する水平方向に併設するとともに、この掻き込みオーガと粉砕オーガの間に仕切板を介在させ掻き込み室と粉砕室に分割し、掻き込み室では掻き込みオーガにて雪を掻き込み後方の粉砕室に送り、粉砕室では粉砕オーガにて送り込まれた雪を細かく粉砕し、この粉砕室に前記熱風発生装置より吹出す熱風が供給されるよう熱風吹出口を設けたことにより、粉砕オーガにより圧雪や氷となった雪も粉砕できるので、熱風による融雪効率が向上し、安定した作業スピードでスムーズな融雪作業が行える。
【0009】
又、熱風発生装置は、バーナーと放熱板とブロワから構成され、放熱板は、オーガハウジングの粉砕室の外周壁面に沿うように配置され、バーナーで放熱板を加熱することで放熱板は放熱し、さらに放熱板と重合する粉砕室の外周壁に複数の熱風吹出口を設け、放熱板より放熱された熱をブロにて粉砕室内に送風することにより、加熱された放熱板に雪を直接接触させることがなくなるので、放熱板は冷却されることがなく安定した熱を供給することができ、融雪効率が良くスムーズな融雪作業が行える。
【0010】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。図1は本発明における自走型融雪装置の一部断面とした側面図、図2は粉砕室を示すA−A断面図である。
【0011】
本発明における自走型融雪装置は、走行可能とした台車1と、この台車1の前方部に雪を掻き込むオーガハウジング2と、台車1上に載置され熱風を吹き出す熱風発生装置3から構成される。
【0012】
1の台車は、台車枠11と、この台車枠11に載置したエンジン12と、台車枠11の両側部に配置し接地させ回転可能としたクローラ13,13と、このククローラ13,13を回転駆動するためエンジン12より出力される回転動力を入力し、ベルト伝達手段を介しクローラ13,13へ出力する走行ミッション14と、走行操作と融雪操作を行う操作部15から構成される。
【0013】
2のオーガハウジングは台車1の前方部に配置され、前方に開口部を有した箱体21で内部前方には掻き込みオーガ22と、後方には粉砕オーガ23を進行方向Fに対し直交する水平方向に併設し、併設された掻き込みオーガ22と粉砕オーガ23の中間部に仕切板24を介在させ、箱体21の前方部を掻き込み室25、後方部を粉砕室26に分割し構成される。
【0014】
掻き込み室25に備えられた掻き込みオーガ22は螺旋体で、外周縁を鋸刃状とし、前記エンジン12より出力される回転動力をベルト伝達手段を介しオーガ駆動軸27へ入力し、掻き込みオーガ22の長手方向中央部に配置した掻き込みオーガ駆動ケース28を介し回転駆動され、箱状21の前方開口部より積雪を掻き込み、掻き込まれた雪を後方の粉砕室26内へ送る。外周縁を鋸刃状としてあるので、圧雪や氷となった雪もスムーズに掻き込むことができる。
【0015】
粉砕室26に備えられた粉砕オーガ23は、図2に示すように大刃と小刃からなる粉砕刃23aを複数列設け構成され、回転駆動されるオーガ駆動軸27より粉砕オーガ23の長手方向中央部に設けた粉砕オーガ駆動ケース29を介し回転駆動される。又、粉砕オーガ23の回転軌跡と一致する粉砕室26の内壁面と仕切板24には、それぞれ固定刃26a,26aが粉砕刃23aと重合するよう間隔をおいて複数列設けてある。このように構成することにより、掻き込みオーガ22より送り込まれた雪、特に圧雪や氷となった雪を細かく粉砕することができる。
【0016】
3の熱風発生装置は、バーナー31と、ブロワ32と、放熱板33から構成され、バーナー31は燃焼筒31aと、燃焼筒31aの内部に燃焼装置31bが設けてあり、燃焼装置31bは、前記台車1上に載置された燃料タンク34より燃料が供給され燃料を噴出するとともに点火し、燃焼筒31a内で燃料を燃焼させる。ブロワ32は燃焼筒31aに接続され、回転可能に設けたファン32aを回転させることにより、燃焼筒31a内で燃焼する燃料から発生する燃焼ガスを送風する。放熱板33は、前記オーガハウジング2の粉砕室26の上方の外周壁面に沿うよう、前記バーナー31の燃料筒31aと接続したケーシング33a内に配置され、バーナー31にて直接加熱される。加熱された放熱板33は、放熱する熱によりオーガハウジング2の粉砕室26を上面より広範囲にわたり温め、粉砕室26内を温室とする。
【0017】
オーガハウジング2の粉砕室26の上方の外周壁面には、複数の熱風吹出口26bが設けられ、バーナー31にて加熱された放熱板33より放熱する熱をブロワ32にて粉砕室26内に送風し、粉砕室26内を熱風が循環する。そして、粉砕オーガ23にて細かく粉砕された雪は、熱風が循環する粉砕室26内で撹拌されながら融雪される。
【0018】
【発明の効果】
以上のように構成された自走型融雪装置は、オーガハウジング内に備えた掻き込みオーガにて掻き込まれた圧雪や氷となった雪を後方に併設した粉砕オーガにて細かく粉砕することができるので、熱風発生装置より供給される熱風にて効率良く融雪することができるので安定した作業スピードでスムーズな融雪作業が行える。
【0019】
又、熱風発生装置のバーナーで過熱される放射板を粉砕室の上方に沿わせるよう配置したので、粉砕室内に広範囲で放射するとともに粉砕した雪が放射板に直接接触することがないので、放射板は冷却されることなく安定した熱を粉砕室内へ供給することができ、融雪効率が向上しスムーズな融雪作業が行える。
