Description

【0001】
【発明の属する技術分野】
本発明は、除雪用のオーガなどの除雪作業部を機体の前部に設けた除雪機に関する。
【0002】
【従来の技術】
路面や駐車場などの雪を除雪するものとしてオーガを備えた除雪機がある(例えば、特許文献1参照。)。
【0003】
【特許文献1】
特開昭63―97705号公報(第3頁、第3図)
【0004】
図8は特許文献1の第3図の断面図である。なお、符号を振り直した。
除雪用のオーガ装置100は、ブロアハウジング101内にブロア102を回転自在に配置し、このブロアハウジング101の前部にオーガハウジング104を設け、ブロアハウジング101とオーガハウジング104とを集雪口105で連通し、オーガハウジング104内に左右のオーガ106,106を回転自在に配置したものである。
【0005】
ブロア102を回転軸107で回転するとともに、回転軸107の回転をオーガミッション108に伝え、オーガミッション108で左右のオーガ軸109,109(右側は図示せず)を回転することにより左右のオーガ106,106を回転する。
【0006】
このオーガ装置100によれば、左右のオーガ106,106を回転することにより、左右のオーガ106,106で雪111を、オーガ装置100の幅方向中央に掻き集める。
掻き集めた雪111を開口部105を経てブロアハウジング101内に導き、ブロアハウジング101内に導いた雪111をブロア102で跳ね上げ、跳ね上げた雪111をシュータ112で案内して所望の位置に投雪する。
【0007】
【発明が解決しようとする課題】
ここで、オーガ装置100は、ブロアハウジング101を円筒形とし、この円筒形のブロアハウジング101をオーガハウジング104の底部104aから所定高さHだけ浮かせて、ブロアハウジング101の前端をオーガハウジン104の背面に取り付ける。
このため、オーガハウジング104の底部104aと開口部105とに段差113ができる。
【0008】
左右のオーガ106,106で掻き集めた雪111を、オーガハウジング104から開口部105を介してブロアハウジング101に導く際に、オーガハウジング104の底部104aの雪111が段差113に当たって段差113の前方に溜まってしまう。
したがって、左右のオーガ106,106で掻き集めた雪111の全てを、ブロアハウジング101内に導くことが難しく、そのことが除雪効率を高める妨げになっていた。
【0009】
そこで、本発明の目的は、オーガで掻き集めた雪をブロアハウジング内に効率よく導くことができる除雪機を提供することにある。
【0010】
【課題を解決するための手段】
上記目的を達成するために請求項1は、オーガハウジングの下端部を後方に向けて上り勾配の傾斜角で形成し、前記オーガハウジング内の雪をオーガで掻き集め、掻き集めた雪をブロアハウジング内のブロアで跳ね上げ、跳ね上げた雪をシュータで案内して所望位置に投雪する除雪機において、前記ブロアハウジングの前端のうち下部前端を他の前端より後方に形成し、前記下部前端の前方に、前記オーガハウジングの底部から下端部近傍まで延びる三角形開口部を形成し、前記オーガハウジングの前記三角形開口部および前記ブロアハウジングの前記下部前端をスロープ部で塞ぐことで、前記スロープ部を前記下端部近傍から前記下部前端に向けて上り勾配に設け、前記スロープ部の上り勾配の傾斜角を、前記スロープ部の左右側に位置する前記下端部の傾斜角より小さく設定したことを特徴とする。
【0011】
オーガハウジングの後面にブロアハウジングを接続し、オーガハウジングの下端部近傍からブロアハウジングの下部前端まで延びる上り勾配のスロープ部を設けた。スロープ部を設けることで、オーガハウジングの底部の雪をブロアハウジングの下部前端まで導く。
よって、オーガで掻き集めた雪の一部が、オーガハウジングの底部に残らないようにすることができる。
【0012】

なお、ブロアハウジング21およびオーガハウジング22でハウジングユニット30を構成する。
【0014】
このオーガ装置20によれば、エンジン(図示せず)で駆動軸26を回転することにより、ブロア25を回転するとともに、オーガミッションケース23内のオーガミッションを駆動し、このオーガミッションで左右のオーガ軸27,27を回転して左右のオーガ28,28を回転する。
【0015】
左右のオーガ28,28が回転することにより、雪をオーガハウジング22の中央に掻き集め、掻き集めた雪をブロアハウジング21内に導き、ブロアハウジング21内に導いた雪をブロア25で跳ね上げ、跳ね上げた雪をシュータ29で案内して外部に投雪する。
【0016】

【0017】
オーガハウジング22は、湾曲状の背面ブレード34を備え、背面ブレード34の左右端に側面ブレード35,35を取り付けたものである。
背面ブレード34は、頂部に折曲片36を備えるとともに底部37にエッジ38を備え、幅方向中央に折曲片36近傍からエッジ38の先端(オーガハウジング22の下端部近傍)38aまで延びる開口部41を形成する。
【0018】
この開口部41は、略円形に形成した円形開口部42と、略三角形に形成した三角形開口部43とからなる。
円形開口部42は、背面ブレード34の上下方向において略中央に位置し、周縁に沿って後方に折り曲げた接合代44を備える。
三角形開口部43は、背面ブレード34の底部37からエッジ38の先端38aまで延びた開口である。
【0019】
左側面ブレード35は、後縁46を背面ブレード34の湾曲面に沿わせて湾曲状に形成し、前縁47を後縁46と略線対称の湾曲状に形成し、中央に左右のオーガ軸27,27(図1参照)を取り付けるための取付孔48を備える。
右側面ブレード35は、左側面ブレード35と対称形の部材なので、左側面ブレード35と同一符合を付して説明を省略する。
【0020】
ブロアハウジング21は、周壁51を円筒状に形成し、前端51a側を開口するとともに周壁51の下部前端31を前端51aから寸法S1だけ後方に配置し、周壁51の後端51bを後壁52で閉塞し、周壁51に矩形状の筒部53を形成したものである。
【0021】
周壁51の前端51aを接合代44に矢印▲1▼の如く嵌め込み、前端51aと接合代44とを接合することにより、ブロアハウジング21をオーガハウジング22の背面ブレード34に取り付ける。
筒部53は、シュータ29(図1参照)を取り付けるための部材である。
なお、後壁52の中央には駆動軸26(図1参照)を取り付けるための取付孔54を備える。
【0022】
スロープ部33は、後方に向けて角度θ1の傾斜角で緩やかに傾斜させた部材で、前端から後方に向けて略V形の第1接合代56を備えるとともに、後端に第2接合代57を備える。
三角形開口部43の周縁43aにスロープ部33の第1接合代56を矢印▲2▼の如く接合するとともに、スロープ部33の第2接合代57を周壁51の下部前端31に矢印▲3▼の如く接合する。
これにより、三角形の開口部43にスロープ部33を取り付けて、三角形の開口部43をスロープ部33で塞ぐ。
【0023】
図3(a)は本発明に係る除雪機(第1実施形態)のハウジングユニットを示す斜視図、図3(b)は(a)の3b−3b線断面図である。
ハウジングユニット30は、オーガハウジング22の後面に横置き円筒状のブロアハウジング21を接続し、オーガハウジング22のエッジ38の先端38a(オーガハウジングの下端部近傍)からブロアハウジング21の下部前端31に向けてスロープ部33を傾斜角θ1の上り勾配に設けたものである。
【0024】
ここで、ブロアハウジング21を構成する周壁51の下部前端31を寸法S1だけ後方に後退させ(図2も参照)、スロープ部33の第2接合代57を接合する部位を、背面ブレード34から寸法S1だけ後方にずらす。
よって、スロープ部33の第2接合代57を周壁51の下部前端31に接合することで、(b)に示すようにスロープ部33を後方に向けて緩やかな傾斜角θ1にする。
このスロープ部33の傾斜角θ1は、背面ブレード34の傾斜角θ2と比較して、θ1<θ2の関係が成立する。
【0025】
さらに、三角形開口部43を、背面ブレード34の底部37からエッジ38の先端38aまで延ばしたので、スロープ部33をエッジ38の先端38aから備えることができ、雪を円滑にスロープ部33まで導くことができる。
【0026】
次に、第1実施形態の除雪機10の作用を図4に基づいて説明する。
図4(a),(b)は本発明に係る除雪機(第1実施形態)の作用を示す説明図である。
(a)において、オーガ装置20の駆動軸26を矢印の如く回転することにより、ブロア25を回転するとともに、左右のオーガ軸27,27で左右のオーガ28,28を回転する。
左右のオーガ28,28が回転することにより、雪58((b)参照)をオーガハウジング22の中央に矢印▲4▼の如く掻き集める。
【0027】

【0028】
よって、左右のオーガ28,28で掻き集めた雪58の一部が、オーガハウジング22の底部37に残らない。これにより、左右のオーガ28,28で掻き集めた雪58を、オーガハウジング22内に残さないで、ブロアハウジング21に効率よく導くことができる。
そして、ブロアハウジング21内に導いた雪58をブロア25で跳ね上げて、跳ね上げた雪58をシュータ29(図1参照)で案内して外部に投雪する。
【0029】
次に、第2実施形態を図5〜図7に基づいて説明する。なお、第2実施形態において第1実施形態と同一部材については同一符合を付して説明を省略する。
図5は本発明に係る除雪機(第2実施形態)のハウジングユニットを示す分解斜視図である。

すなわち、ブロアハウジング61は、第1実施形態のブロアハウジング21とスロープ部33とを一体成形したものである。
したがって、ハウジング本体62は、第1実施形態のブロアハウジング21と略同一の部材であり、スロープ部65は、第1実施形態のスロープ部33と略同一の部材である。
【0031】
スロープ部65は、その後端66を、周壁63の前端63aから後方に寸法S2だけ後方にずらせている。
さらに、スロープ部65は、後方に向けて角度θ3の傾斜角で緩やかに傾斜させた部材で、前端から後方に向けて略V形の接合代67を備える。
【0032】
ブロアハウジング61をオーガハウジング22の後面に取り付ける際には、周壁63の前端63aを接合代44に矢印▲6▼の如く嵌め込み、前端63aと接合代44とを接合するとともに、スロープ部65の接合代67を三角形開口部43の周縁43aに矢印▲7▼の如く接合する。
これにより、ブロアハウジング61をオーガハウジング22の背面ブレード34に取り付けるとともに、三角形の開口部43をスロープ部65で塞ぐ。
【0033】
図6(a)は本発明に係る除雪機(第2実施形態)のハウジングユニットを示す斜視図、図6(b)は(a)の6b−6b線断面図である。
ハウジングユニット60は、オーガハウジング22の後面に横置き円筒状のブロアハウジング61を取り付けたものである。
【0034】
ここで、スロープ部65の後端66を、周壁63の前端63aから後方に寸法S2だけ後方にずらせ、スロープ部65を、オーガハウジング22のエッジ38の先端38a(オーガハウジングの下端部近傍)からハウジング本体62の下部前端64に向けて傾斜角θ3で緩やかに傾斜させている。
このスロープ部65の傾斜角θ3は、背面ブレード34の傾斜角θ2と比較して、θ3<θ2の関係が成立する。なお、スロープ部65の傾斜角θ3を、第1実施形態のスロープ部33の傾斜角θ1と同一にすることも可能である。
【0035】
さらに、三角形開口部43を、背面ブレード34の底部37からエッジ38の先端38aまで延ばしたので、スロープ部65をエッジ38の先端38aから備えることができ、雪を円滑にスロープ部65まで導くことができる。
【0036】
次に、第2実施形態の除雪機の作用を図7に基づいて説明する。
図7(a),(b)は本発明に係る除雪機(第2実施形態)の作用を示す説明図である。
(a)において、オーガ装置20の駆動軸26を矢印の如く回転することにより、ブロア25を回転するとともに、左右のオーガ軸27,27で左右のオーガ28,28を回転する。
左右のオーガ28,28が回転することにより、雪58((b)参照)をオーガハウジング22の中央に矢印▲8▼の如く掻き集める。
【0037】
(b)において、オーガハウジング22のエッジ38からハウジング本体62の下部前端64に向けて上り勾配のスロープ部65を設けた。スロープ部65を設けることで、オーガハウジング22の底部37中央に掻き集めた雪58をハウジング本体62の下部前端64まで矢印▲9▼((a)も参照)の如く円滑に導く。
【0038】
よって、左右のオーガ28,28で掻き集めた雪58の一部が、オーガハウジング22の底部37に残らない。これにより、左右のオーガ28,28で掻き集めた雪58を、オーガハウジング22内に残さないで、ハウジング本体62に効率よく導くことができる。
そして、ハウジング本体62内に導いた雪58をブロア25で跳ね上げて、跳ね上げた雪58をシュータ29(図1参照)で案内して外部に投雪する。
【0039】
なお、前記第2実施形態では、スロープ部65をハウジング本体62に一体に成形した例について説明したが、これに限らないで、スロープ部65をオーガハウジング22に一体に形成することも可能である。
また、前記実施形態のオーガハウジング22、ブロアハウジング21、ハウジング本体62およびスロープ部33,65は、前記実施形態に示す形状に限定するものではなく、適宜好適な形状に変更することが可能である。
【0040】
【発明の効果】
本発明は上記構成により次の効果を発揮する。
請求項1は、オーガハウジングの後面にブロアハウジングを接続し、オーガハウジングの下端部近傍からブロアハウジングの下部前端まで延びる上り勾配のスロープ部を設けた。スロープ部を設けることで、オーガハウジングの底部の雪をブロアハウジングの下部前端まで導く。
【0041】
よって、オーガで掻き集めた雪の一部が、オーガハウジングの底部に残らないようにすることができる。これにより、オーガで掻き集めた雪を、オーガハウジング内に残さないで、ブロアハウジングに効率よく導いて、除雪効率を高めることができる。
【0042】
加えて、掻き集めた雪の一部をオーガハウジングの底部に残らないようにすることで、底部に残った雪で除雪機の前進を妨げることがなく、除雪効率をさらに高めることができる。
さらに、オーガハウジングの底部に残った雪で底部が摩耗することを防ぐこともできる。
