Description

【0001】
【発明の属する技術分野】
本発明は、主に、適宜木材(例えば、間伐材や、剪定材や、廃材や、その他)等や、その他の適宜被破砕物を確実に破砕できるようにした破砕装置に係り、特に、適宜木材等にあっては、堆肥や、畜舎の寝藁や、その他として利用可能となるようなウッドチップ等を能率良く形成でき、加えて、適宜被破砕物を破砕する一対の破砕ローラの破砕歯部分が損耗し難く、しかも、損耗した場合であってもその破砕歯部分を簡単に交換できるように工夫した経済的な破砕装置に関するものである。
【0002】
【従来の技術】
従来、この種の破砕装置としては種々のものが提供されており、その殆どは、例えば、ケーシング内に一対のシャフトを駆動回転可能に設け、この一対のシャフトに回転切断刃を多数設けた構成のものが創出されている。
【0003】
【発明が解決しようとする課題】
ところが、従来の破砕装置にあっては、被破砕物の破砕をある程度続けて回転切断刃の刃部が損耗すると、極端にその破砕能率が低下する難点や、刃部自体が損耗し易い難点があり、しかも、損耗した回転切断刃は、その交換コスト等が高くなり、経済的な負担が大きい等の難点があった。
また、従来の破砕装置にあっては、被破砕物の破砕負荷が大きくなると、回転切断刃が損傷し易くなると共に、回転切断刃の回転が停止してしまう虞れ等もあった。
更に、従来の破砕装置にあっては、適宜木材等の被破砕物を破砕した場合、回転切断刃の剪断作用によって細かく破砕することは可能であるが、破砕されたウッドチップ夫々の繊維がほぐれるようになるものは少なく、これらウッドチップを、例えば、堆肥、畜舎の寝藁等に利用するには、最適なものとなってはいない難点があった。
【0004】
【課題を解決するための手段】
そこで、本発明は、前述の如き難点等を解消すべく創出されたもので、請求項1記載の破砕装置にあっては、木材等やその他の適宜被破砕物を一対の破砕ローラSで破砕できるように構成した破砕装置であって、上方に送給口が、下方に排出口が夫々設けられているケーシングBと、このケーシングB内に回転自在に軸架されると共に、略平行で且つ略水平に配される一対の破砕ローラSと、一対の破砕ローラSを同期回転せしめる適宜駆動手段と、ケーシングB上方の送給口に設けられるホッパーCと、このホッパーC内に回転自在に軸架されると共に、破砕ローラSに対して略平行で、且つ略水平に配される一対の送給ローターTと、一対の送給ローターTを回転せしめる適宜駆動手段と、ケーシングB下方の排出口部分に設けられる超過寸法の被破砕物を通さないパンチングプレート等からなるスクリーンとを備え、一対の送給ローターTは、ホッパーC内壁との間に於いて投入された被破砕物を上方から下方に向って順次送り込めるような向きに回転して、ホッパーC内に投入される被破砕物をケーシングB内に送給できるように構成し、一対の破砕ローラSによる被破砕物の破砕負荷が所定値となったときに、一対の送給ローターTの回転を停止或いは回転を遅くして、ホッパーC内の被破砕物の送給を停止或いは遅延できるように構成し、一対の破砕ローラSは、ケーシングBの周胴板と破砕ローラSとの間部分に於いて、ホッパーCからの被破砕物をケーシングBの周胴板に沿うように上方から下方に向って送給できるような向きに駆動回転せしめられ、一方、一対の破砕ローラS相互が接近している干渉部分に於いて、重力に抗して被破砕物を下方から上方に向って巻込むようにして破砕できるよう構成する手段を採用した。
【0005】
また、請求項2記載の破砕装置にあっては、破砕ローラSは、その中央に軸孔2が穿設されている複数の破砕板S1を、駆動回転軸S2に装着することにより構成され、破砕板S1は、破砕基板1と、この破砕基板1の外周部に互換可能に装着される複数の破砕歯体10と、この破砕歯体10を破砕基板1に装着固定する複数の連結ピン20とを備え、破砕歯体10を配した部分が凸部S4となり、回転方向で隣設する凸部S4の間が凹部S5となるように構成し、一対の駆動回転軸S2に装着される一組の破砕板S1は、一方の破砕板S1の凸部S4或いは凹部S5と、他方の破砕板S1の凹部S5或いは凸部S4とが略噛合うように形成されると共に、同期回転時に、その外周面が常に接触した状態或いは常に接近した状態となるように形成され、被破砕物を押し潰すようにして破砕できるよう構成する手段を採用した。
【0006】
更に、請求項3記載の破砕装置にあっては、破砕ローラSは、その中央に軸孔2が穿設されている複数の破砕板S1を、駆動回転軸S2に装着することにより構成され、破砕板S1は、破砕基板1と、この破砕基板1の外周部に互換可能に装着される複数の破砕歯体10と、この破砕歯体10を破砕基板1に装着固定する複数の連結ピン20とを備え、破砕歯体10は、駆動回転軸S2の軸心に直交する平面内に於いて、所定の放射方向に移動せしめて破砕基板1に互換装着可能となるよう構成する手段を採用した。
【0007】
そして、請求項4記載の破砕装置にあっては、連結ピン20は、破砕基板1に設けた連結孔5と、破砕歯体10に設けた連結孔13とを貫通するようにして装着され、連結ピン20の貫通方向を、破砕歯体10が移動可能となる所定の放射方向に対して直交する方向であって、且つ駆動回転軸S2によって回転する破砕基板1の接線方向に略沿うような方向に配して構成する手段を採用した。
【0008】
それから、請求項5記載の破砕装置にあっては、一対の破砕ローラSに於ける一対の駆動回転軸S2に装着される複数組の破砕板S1は、駆動回転軸S2の軸心方向で隣設する一組の破砕板S1毎に、破砕歯体10の位置が回転方向でズレるように構成する手段を採用した。
【0009】
また、請求項6記載の破砕装置にあっては、破砕ローラSは、その中央に軸孔2が穿設されている複数の破砕板S1aを、駆動回転軸S2に装着することにより構成され、破砕板S1aは、破砕基板1Aと、この破砕基板1Aの外周部に互換可能に装着される複数の破砕歯体10Aと、この破砕歯体10Aを破砕基板1Aに装着固定する固定ネジ22とを備え、破砕歯体10Aを配した部分が凸部S4となり、回転方向で隣設する凸部S4の間が凹部S5となるように構成し、一対の駆動回転軸S2に装着される一組の破砕板S1aは、一方の破砕板S1aの凸部S4或いは凹部S5と、他方の破砕板S1aの凹部S5或いは凸部S4とが略噛合うように形成されると共に、同期回転時に、その外周面が常に接触した状態或いは常に接近した状態となるように形成され、被破砕物を押し潰すようにして破砕できるよう構成する手段を採用した。
【0010】
更に、請求項7記載の破砕装置にあっては、破砕ローラSは、その中央に軸孔2が穿設されている複数の破砕板S1aと、その中央に軸孔2が穿設されている複数のスペーサー24とを、駆動回転軸S2に交互に装着することにより構成され、破砕板S1aは、破砕基板1Aと、この破砕基板1Aの外周部に互換可能に装着される複数の破砕歯体10Aと、この破砕歯体10Aを破砕基板1Aに装着固定する固定ネジ22とを備え、破砕歯体10Aを配した部分が凸部S4となり、回転方向で隣設する凸部S4の間が凹部S5となるように構成し、一対の駆動回転軸S2に装着される一組の破砕板S1aは、一方の破砕板S1aの凸部S4或いは凹部S5と、他方の破砕板S1aの凹部S5或いは凸部S4とが略噛合うように形成されると共に、同期回転時に、その外周面が常に接触した状態或いは常に接近した状態となるように形成され、被破砕物を押し潰すようにして破砕できるよう構成し、破砕歯体10Aには適宜フィン16を固着して、破砕ローラSの回転時にフィン16による所定向きの空気の流れが生じるように構成する手段を採用した。
【0011】
【発明の実施の形態】
以下、本発明を図示例に基づいて説明すると、次の通りである。
本発明は、例えば、一次破砕機等によってある程度の大きさ以下に予め切断された適宜木材(例えば、間伐材や、剪定材や、廃材や、その他)等やその他の適宜被破砕物を、更に細かく破砕(二次破砕)できるようにしたもので、例えば、適宜木材等の被破砕物にあっては、比較的細かなウッドチップ状に破砕して、堆肥や、畜舎の寝藁や、厚層基盤材(適宜破砕して腐食させた木材と、植物の育成に必要な材料と、適宜種子とからなる)や、その他等として利用できるようにした破砕装置である。
【0012】
そして、この破砕装置は、適宜型材等によって安定性良く且つ堅牢に組立てられる適宜基枠Aと、この基枠A上部に固定されると共に、上方に送給口が、下方に排出口が夫々設けられているケーシングBと、このケーシングB内に回転自在に軸架されると共に、略平行で且つ略水平に配される一対の破砕ローラSと、一対の破砕ローラSの干渉(中央)部分に於いて被破砕物を下方から上方に向って巻込むような向きに一対の破砕ローラSを同期回転せしめる適宜駆動手段(駆動部E)と、ケーシングB上方の送給口に設けられるホッパーCと、このホッパーC内に回転自在に軸架されると共に、破砕ローラSに対して略平行で、且つ略水平に配される一対の送給ローターTと、一対の送給ローターTとホッパーC内壁との間に於いて被破砕物を上方から下方に向って送給するような向きに一対の送給ローターTを同期回転せしめる適宜駆動手段(駆動部E)と、ケーシングB下方の排出口部分に設けられる超過寸法の被破砕物を通さないパンチングプレート等からなるスクリーンと、ケーシングB下方に設けられるスクリューフィーダ等の搬送部Dとを備えたものである(図1、図2、図3参照)。
【0013】
前記基枠Aは、例えば、適宜アングル材や適宜型材等によって、堅牢で、強固に構成されると共に、機能的で、安定性良く配置できるように構成されたものが採用される。尚、基枠Aの具体的構成、形状、寸法、材質等は図示例等に限定されることなく適宜自由に設定、変更できるものである。
【0014】
前記ケーシングBは、例えば、適宜金属板等によって構成されており、縦断面略横向き3状に湾曲形成される周胴板と、この周胴板の左右側部を塞ぐ左右側板とによって構成され、上部にはホッパーCに連続する送給口が設けられ、下部には搬送部Dに連続する排出口が設けられている。しかも、ケーシングBの排出口部分には、適宜金属板に適宜寸法、形状の透孔を多数穿設してなるパンチングプレートの如きスクリーンが取外し可能に装着されており、所定寸法以下の被破砕物を通過させて、超過寸法の被破砕物を搬送部Dがわに通さないように構成されている。
【0015】
ところで、ケーシングBには、その一部が開閉自在となるような窓部と開閉扉を設けておき、後述する破砕歯体10の互換装着作業が行い易くなるようにしてあっても良い(図示せず)。
【0016】
尚、ケーシングBの具体的構成、形状、寸法、材質、配設位置、周胴板の具体的構成、形状、左右側板の具体的構成、形状、送給口の具体的構成、形状、寸法、配設位置、排出口の具体的構成、形状、寸法、配設位置、スクリーンの具体的構成、形状、寸法、材質、配設位置、排出口部分への具体的取付け手段、小孔の具体的形状、寸法、数、配設位置等は図示例等に限定されることなく適宜自由に設定、変更できるものである。
【0017】
前記ホッパーCは、適宜金属板等によって構成されており、ケーシングBの送給口に連続するように設けられており、ケーシングBに対して取外し可能となるように構成されている。しかも、ホッパーCは、上部の投入口がわに行くに従って漸次拡開するように形成されると共に、投入口の間口が広いものが採用され、被破砕物をスムーズにケーシングB内に投入できるように形成されている。
尚、ホッパーCの具体的構成、形状、寸法、材質、配設位置、送給口への具体的連設手段等は図示例等に限定されることなく適宜自由に設定、変更できるものである。
【0018】
そして、ホッパーC内下部には、一対の送給ローターTが回転自在に軸架されており、この一対の送給ローターTは、相互に略平行で且つ略水平となるように配されている。しかも、一対の送給ローターTは、ホッパーC上部の投入口から投入された被破砕物をホッパーCの周壁寄りに於いて上方から下方に向って順次送り込めるように、適宜駆動手段(駆動部E)を介して同期回転せしめられるように構成されている。
【0019】
また、送給ローターTは、適宜金属材や、その他の適宜材料によって構成され、比較的太い略円筒状の軸部30の外表面に、複数の突出杆部31を適宜間隔に突設せしめることにより構成されており、一次破砕された被破砕物がケーシングB内にスムーズに送られるようにすると共に、被破砕物が所定の姿勢で安定的に且つ平均的にケーシングB内に送られるように構成してある。すなわち、被破砕物が一度に纏まって一対の破砕ローラSに送られてしまい、一対の破砕ローラSの駆動回転が停止したり、或いは、一対の破砕ローラSの駆動回転時に於ける負荷(破砕負荷)が極端に大きくならないように配慮してある。
しかして、一対の送給ローターTは、一対の破砕ローラSによる被破砕物の破砕負荷が所定値となったときに(例えば、一対の破砕ローラSを駆動回転せしめる駆動部Eとなるギャードモータに流れる電流が所定値となったときに)、自動制御装置等によって一対の送給ローターTを回転せしめている駆動部Eとなるギャードモータを停止せしめて(或いは、回転速度を遅くして)、ホッパーC内の被破砕物のケーシングB内への送給を自動的に停止(或いは、遅延)できるように構成されている。
【0020】
尚、送給ローターTの具体的構成、形状、寸法、材質、配設位置、軸部30の具体的構成、形状、寸法、材質、突出杆部31の具体的構成、形状、寸法、材質、数、配設位置、一対の送給ローターTを駆動せしめる駆動手段(駆動部E)の具体的構成、配設位置等は図示例等に限定されることなく適宜自由に設定、変更できるものである。
【0021】
前記搬送部Dは、前記スクリーンを通過してきた被破砕物を所定位置に連続的に搬送できるようにしたもので、例えば、斜上向きに並設させた一対のスクリューフィーダ等によって構成されている。尚、搬送部Dの具体的構成、形状、材質、配設位置等は図示例等に限定されることなく適宜自由に設定、変更できるものである。
【0022】
次に、ケーシングB内に配される一対の破砕ローラSは、適宜間隔を隔てて略平行で且つ略水平に配される一対の駆動回転軸S2と、その中央に軸孔2が穿設されて一対の駆動回転軸S2に夫々装着される複数の破砕板S1と、この破砕板S1に適宜穿設した適数(例えば、4個)の貫通孔3に挿通される適数の貫通杆S3とで構成され、破砕板S1は、略厚板状に構成されると共に、その外周部分に複数(例えば、4つ)の凸部5と複数の(例えば、4つ)凹部6とを交互に配して構成されている。
【0023】
そして、破砕板S1は、破砕基板1と、この破砕基板1の外周部に互換可能に装着されると共に、被破砕物を直接的に破砕する複数の破砕歯体10と、この破砕歯体10を破砕基板1に装着固定する複数の連結ピン20とを備えた構成となっている。すなわち、破砕歯体10を配した部分が略湾曲凸状の前記凸部S4となり、回転方向で隣設する凸部S4の間が略湾曲凹状の前記凹部S5となるように構成してある。
【0024】
しかも、一対の駆動回転軸S2に装着される一組の破砕板S1は、一方の破砕板S1の凸部S4或いは凹部S5と、他方の破砕板S1の凹部S5或いは凸部S4とが略噛合うように形成されると共に、同期回転時に、その外周面が常に接触した状態或いは常に接近した状態となるように構成されている(図3参照)。加えて、一対の破砕ローラSは、ケーシングBの周胴板と破砕ローラSとの間部分に於いて、ホッパーCからの被破砕物をケーシングBの周胴板に沿うように上方から下方に向って送給できるような向きに駆動回転せしめられ、一方、一対の破砕ローラS相互が接近している干渉(中央)部分に於いて、重力に抗して被破砕物を下方から上方に向って巻込むようにして破砕できるよう形成されている。すなわち、一対の破砕ローラS相互が接近している干渉(中央)部分に被破砕物が一度に送り込まれて、一対の破砕ローラSが被破砕物の噛み込みによって停止することがないように構成されている。
【0025】
前記破砕基板1は、例えば、略十字状を呈する適宜金属製厚板で構成され、その中央部分には円孔状の軸孔2が穿設され、この軸孔2の周囲には、略細長丸棒状の貫通杆S3が嵌挿される略円孔状の貫通孔3が適数(例えば、4個)穿設され、破砕歯体10が装着される部分には、略直方体状の金属製突出ブロック4が突設されている。
【0026】
そして、軸孔2には、駆動回転軸S2に設けたキー25に合致するキー溝2aが設けられている。ただし、駆動回転軸S2に於いてキー25が設けてない部分に装着される破砕基板1の軸孔2にはキー溝2aを設けなくても良い。すなわち、駆動回転軸S2に装着される複数の破砕基板1の内の一部(例えば、駆動回転軸S2の両端がわにある破砕基板1)が、キー25とキー溝2aを介して駆動回転軸S2に連繋されて、駆動回転軸S2の駆動回転力が伝達され、他の破砕基板1には、貫通孔3に貫通される貫通杆S3を介して駆動回転軸S2の駆動回転力が伝達されるように構成してある。ところで、キー溝2aを設けてない破砕基板1にあっては、貫通孔3の穿設位置をその回転方向に於いて僅かにズラす(例えば、回転方向に於いて2度宛ズラす)ことによって、隣設する破砕基板1の凸部S4(破砕歯体10)の位置を回転方向に於いて簡単に且つ正確にズラすことができるように構成されている(図7参照)。
また、前記突出ブロック4には、連結ピン20が挿通される略円孔状の連結孔5が穿設されている。しかも、この連結孔5は、その中心線が回転する破砕基板1の接線方向に略沿うように配されている。
【0027】
前記破砕歯体10は、先端がわが略円弧状となるような正面略舌片状を呈し、基端がわの取付部11と、先端がわの歯部15とからなっている。しかも、取付部11の基端中央には前記破砕基板1の突出ブロック4が嵌合可能となる嵌合溝12が切設され、この嵌合溝12を挟む取付部11の基端がわ左右には、嵌合溝12を跨ぐように連結ピン20が貫通可能となる略円孔状の連結孔13が穿設されている。すなわち、破砕歯体10は、駆動回転軸S2の軸心に直交する平面内に於いて、所定の放射方向に移動自在となるように構成され、駆動回転軸S2に複数の破砕基板1が装着されている状態のままであっても、隣設する破砕板S1が邪魔になることなく、所望の破砕歯体10を簡単に互換装着可能となるよう構成されている。ところで、破砕歯体10の破砕基板1への装着は、破砕歯体10に突出ブロック4を設け、破砕基板1に嵌合溝12を設けるようにしても良い(図示せず)。
【0028】
更に、破砕歯体10の前記歯部15は、取付部11よりも薄く形成され、その先端縁部分には、略円弧状の浅溝が回転方向に対して直交する向きに切設されると共に、回転方向に沿って適宜間隔に配されており、この先端縁部分で被破砕物を押し潰すようにして、確実に且つ細かく破砕できるように構成されている。すなわち、適宜木材等の被破砕物を破砕するような場合には、その繊維方向に沿って破砕すると共に、被破砕物をその繊維方向に対して直交する方向から圧迫するようにし、繊維がほぐれるようになって、被破砕物をバランス良く、且つ効率良く破砕できるように構成されている。
【0029】
前記連結ピン20は、適宜金属製の略丸棒状を呈し、破砕基板1の突出ブロック4に設けた連結孔5と、破砕歯体10の取付部11に設けた連結孔13とを貫通して装着できるように形成されるものである。しかも、この連結ピン20は、その貫通方向が、破砕歯体10が移動可能となる所定の放射方向に対して直交する方向であって、且つ駆動回転軸S2によって回転する破砕基板1の接線方向に略沿うような方向に配してある。すなわち、駆動回転軸S2に複数の破砕板S1が装着されている状態のままであっても、隣設する破砕板S1が邪魔になることなく、所望の破砕歯体10を連結している連結ピン20を簡単に引き抜いたり、挿入したりできるように構成されている。
【0030】
加えて、連結ピン20は、適宜係止手段によって破砕歯体10の連結孔13に係止できるように構成されている。具体的には、例えば、連結ピン20の一端部分を細径に形成すると共に、この細径部分に略C字状のストッパーリング21を着脱自在に装着できる細溝を周設して構成されている。そして、破砕歯体10の一方の連結孔13内に設けた段部を、連結ピン20の細径部分に設けた段部とストッパーリング21とによって挟むようにすることで、連結ピン20が連結孔5,13に貫通されている状態を確実に且つ安定的に維持できるように構成されている(図5参照)。
【0031】
尚、破砕板S1の具体的構成、形状、寸法、材質、数、配設位置、駆動回転軸S2の具体的構成、形状、寸法、材質、貫通杆S3の具体的構成、形状、寸法、材質、数、配設位置、凸部S4の具体的構成、形状、寸法、数、配設位置、凹部S5の具体的構成、形状、寸法、数、配設位置、破砕基板1の具体的構成、形状、寸法、材質、軸孔2の具体的構成、形状、寸法、キー溝2aの具体的構成、形状、寸法、配設位置、数、貫通孔3の具体的構成、形状、寸法、数、配設位置、突出ブロック4の具体的構成、形状、寸法、材質、配設位置、連結孔5の具体的構成、形状、寸法、数、配設位置、破砕歯体10の具体的構成、形状、寸法、材質、数、取付部11の具体的構成、形状、寸法、材質、嵌合溝12の具体的構成、形状、寸法、数、配設位置、連結孔13の具体的構成、形状、寸法、配設位置、歯部15の具体的構成、形状、寸法、材質、連結ピン20の具体的構成、形状、寸法、材質、ストッパーリング21の具体的構成、形状、寸法、材質、配設位置、キー25の具体的構成、形状、寸法、数、配設位置等は図示例等に限定されることなく適宜自由に設定、変更できるものである。
【0032】
ところで、一対の破砕ローラSに於ける一対の駆動回転軸S2に装着される複数組の破砕板S1は、駆動回転軸S2の軸心方向で隣設する一組の破砕板S1毎に、破砕歯体10の位置が回転方向でズレるように構成されている(図7参照)。すなわち、駆動回転軸S2の両端がわにある破砕板S1の凸部S4(破砕歯体10)に対して、他の破砕板S1の凸部S4(破砕歯体10)が駆動回転軸S2の軸心方向中央寄りとなるに従って漸次回転方向に於いて先行(或いは、後退)するように配されており、平面から見て複数の破砕板S1の凸部S4(或いは凹部S5)が緩やかな略弧状を描くように配されて、被破砕物をバランス良く破砕できるように形成されると共に、比較的小さな動力でも被破砕物を確実に破砕できるように形成されている。しかも、一対の破砕ローラSが被破砕物を一度に噛み込むことがなくなり、安定的な破砕作業が可能となり、加えて、一対の破砕ローラSの回転時にケーシングB内に空気の比較的強い流れが生じるように形成され、この比較的強い空気の流れによって、細かく破砕された被破砕物がケーシングBの排出口がわに強制的に送り出せ、ひいては、ケーシングBの排出口にパンチングプレート等のスクリーンの目詰まりを確実に防止できるように形成されている。尚、駆動回転軸S2に装着される複数の破砕板S1の凸部S4(破砕歯体10)の配置状態は、図示例等に限定されることなく適宜自由に設定、変更できるものである。
【0033】
前記駆動回転軸S2は、その両端近傍部分がケーシングBに設けた軸受部分で回転自在となるように支持されており、一方の駆動回転軸S2の一端部分には、適宜ジョイントを介して駆動手段となる駆動用モーター(ギャードモーター)等の駆動部Eからの回転力が伝達されるように形成されている。また、一方の駆動回転軸S2の他端部分及び他方の駆動回転軸S2の他端部分には、一対の歯車が固定されており、一方の駆動回転軸S2の回転に同期して他方の駆動回転軸S2が回転するように構成してある。尚、一対の破砕ローラSの具体的駆動手段は、適宜自由に設定、変更できるものである。
【0034】
更に、搬送部Dも駆動用モーター(ギャードモーター)等の駆動部Eからの回転力が伝達されることによって、搬送部Dのスクリューフィーダが回転するように形成されている。
【0035】
また、図8乃至図10に示す破砕ローラSは、その中央に軸孔2が穿設されている複数の破砕板S1aと、その中央に軸孔2が穿設されている複数のスペーサー24とを、駆動回転軸S2に交互に装着することにより構成されたもので、破砕板S1aは、破砕基板1Aと、この破砕基板1Aの外周部に互換可能に装着される複数の破砕歯体10Aと、この破砕歯体10Aを破砕基板1Aに装着固定する固定ネジ22とを備え、破砕歯体10Aを配した部分が凸部S4となり、回転方向で隣設する凸部S4の間が凹部S5となるように構成し、一対の駆動回転軸S2に装着される一組の破砕板S1aは、一方の破砕板S1aの凸部S4或いは凹部S5と、他方の破砕板S1aの凹部S5或いは凸部S4とが略噛合うように形成されると共に、同期回転時に、その外周面が常に接触した状態或いは常に接近した状態となるように形成され、被破砕物を押し潰すようにして破砕できるよう構成したものである。すなわち、被破砕物は一対の破砕ローラSによって強力に押し潰されるようになり、例えば、適宜木材等の被破砕物にあっては、その繊維方向に沿って細かく且つ均一に破砕できると共に、その繊維がほぐれてソフトな感触が得られるように破砕できるよう構成されている。

それから、破砕歯体10Aには適宜フィン16を固着して、破砕ローラSの回転時にフィン16による所定向きの空気の流れが生じるように構成されている。すなわち、一対の破砕ローラSの回転時にケーシングB内に空気の比較的強い流れが生じるように形成され、この比較的強い空気の流れによって、細かく破砕された被破砕物がケーシングBの排出口がわに強制的に送り出せ、ひいては、ケーシングBの排出口にパンチングプレート等のスクリーンの目詰まりを確実に防止できるように形成されている。
【0037】
前記破砕基板1Aは、例えば、略十字状を呈する適宜金属製厚板で構成され、その中央部分には円孔状の軸孔2が穿設され、この軸孔2の周囲には、略細長丸棒状の貫通杆S3が嵌挿される略円孔状の貫通孔3が適数(例えば、4個)穿設され、破砕歯体10Aが装着される部分は、破砕歯体10Aが収まるような段状に形成されると共に、段上部には固定ネジ22が螺着される複数の雌ネジ孔6が夫々設けられている。
【0038】
尚、駆動回転軸S2に設けたキー25に合致する部分の破砕基板1Aの軸孔2にはキー溝2aが設けられるが、駆動回転軸S2に於いてキー25が設けてない部分に装着される破砕基板1Aの軸孔2にはキー溝2aを設けなくても良い。すなわち、駆動回転軸S2に装着される複数の破砕基板1Aの内の一部(例えば、駆動回転軸S2の両端がわにある破砕基板1A)が、キー25とキー溝2aを介して駆動回転軸S2に連繋されて、駆動回転軸S2の駆動回転力が伝達され、他の破砕基板1Aには、貫通孔3に貫通される貫通杆S3を介して駆動回転軸S2の駆動回転力が伝達されるように構成してある。ところで、キー溝2aを設けてない破砕基板1Aにあっては、貫通孔3の穿設位置をその回転方向に於いて僅かにズラす(例えば、回転方向に於いて2度宛ズラす)ことによって、隣設する破砕基板1の凸部S4(破砕歯体10A)の位置を回転方向に於いて簡単に且つ正確にズラすことができるよう構成しても良い。
【0039】
前記破砕歯体10Aは、適宜金属材によって略厚板状に構成され、先端がわ及び基端がわが略円弧状となるような正面略舌片状を呈し、基端がわの取付部11と、先端がわの歯部15とからなっている。しかも、取付部11の基端寄り左右には前記破砕基板1Aの雌ネジ孔6に合致すると共に固定ネジ22が挿通される取付孔14が穿設されている。また、破砕歯体10Aの前記歯部15は、その先端縁部分に略小円弧状の浅溝が回転方向に対して直交する向きに切設されると共に、回転方向に沿って適宜間隔に配されており、この先端縁部分で被破砕物を押し潰すようにして、確実に且つ細かく破砕できるように構成されている。
【0040】
更に、前記フィン16は、適宜金属材によって略矩形板状に構成され、破砕歯体10Aの側面部分中央に固着(例えば、溶着)されており、破砕ローラSの回転時に於いて、フィン16による所定向きの空気の流れが生じるように(例えば、ケーシングBの送給口から周胴に沿って排出口に空気が向かうように)構成されている。
【0041】
前記スペーサー24は、例えば、適宜金属材(或いは、その他の材料)によって略厚肉円盤状に構成され、その中央に軸孔2が穿設され、この軸孔2の周囲に貫通杆S3が嵌挿される適数(例えば、4個)の貫通孔3が穿設されている。すなわち、スペーサー24は、複数の破砕板S1aの間に介装され、破砕基板1Aや破砕歯体10A程の強度や剛性の高い高価な材料で構成しなくて良いことから、破砕ローラS自体のコストダウンを図れるように構成されている。
【0042】
図中23は、ワッシャで、このワッシャ23は固定ネジ22によって破砕歯体10Aを破砕基板1Aに固定する際に、固定ネジ22が緩まないように設けられるものである。

加えて、一対の送給ローターTは、ホッパーC内壁との間に於いて投入された被破砕物を上方から下方に向って順次送り込めるような向きに回転して、ホッパーC内に投入される被破砕物をケーシングB内に送給できるように構成したので、被破砕物が一度に纏まって一対の破砕ローラSに送られて、一対の破砕ローラSの駆動回転が停止したり、或いは、一対の破砕ローラSの駆動回転時に於ける負荷(破砕負荷)が極端に大きくなるような虞のないものとなる。

【0048】
加えて、被破砕物の破砕を連続的に行っても、破砕板S1が損耗し難いと共に、その破砕能力や破砕能率が低下することがなく、長期に亙って安定的な破砕能力を維持できるようになる。しかも、破砕板S1の破砕能力が低下した場合は、破砕歯体10を互換装着するだけで、元の破砕能力が得られるようになり、取扱いも容易で、構成簡素で、耐久性に優れ、量産に適し、低廉で、経済的に優れた破砕装置となる。
【0049】
そして、破砕板S1は、破砕基板1と、この破砕基板1の外周部に互換可能に装着される複数の破砕歯体10と、この破砕歯体10を破砕基板1に装着固定する複数の連結ピン20とを備えているので、複数の破砕板S1が駆動回転軸S2に装着されたままの状態で、破砕基板1から損耗した破砕歯体10を取外すことが容易に行えるようになると共に、破砕基板1に新しい破砕歯体10を装着することが容易に行えるようになる。

【0053】
更に、一対の破砕ローラSの回転時にケーシングB内に空気の比較的強い流れが生じるようになり、この比較的強い空気の流れによって、細かく破砕された被破砕物がケーシングBの排出口がわに強制的に送り出せるようになる。ひいては、ケーシングBの排出口に配してあるパンチングプレート等のスクリーンの目詰まりを防止することができるようになる。

【The invention's effect】
Therefore, the crushing device according to claim 1 is a crushing device configured to crush wood and other appropriately crushed objects with a pair of crushing rollers S, with a feeding port on the upper side and a discharge port on the lower side. , A pair of crushing rollers S that are rotatably mounted in the casing B and arranged substantially parallel and substantially horizontally, and the pair of crushing rollers S are rotated synchronously. An appropriate driving means, a hopper C provided at a feeding port above the casing B, and a shaft rotatably mounted in the hopper C, and substantially parallel to the crushing roller S and arranged substantially horizontally. A screen comprising a pair of feeding rotors T, appropriate driving means for rotating the pair of feeding rotors T, and a punching plate, etc., which is provided at the discharge port portion below the casing B and does not pass oversized objects to be crushed. The pair of feeding rotors T are rotated in such a direction that the objects to be crushed between the inner walls of the hopper C and the crushed objects can be sequentially fed from the upper side to the lower side. The crushing object to be crushed is fed into the casing B, and when the crushing load of the crushing object by the pair of crushing rollers S reaches a predetermined value, the rotation of the pair of feeding rotors T is stopped or rotated. The pair of crushing rollers S are arranged between the peripheral body plate of the casing B and the crushing rollers S, so that the feeding of the crushing object in the hopper C can be stopped or delayed. The object to be crushed from the hopper C is driven and rotated in such a direction that the object to be crushed along the peripheral plate of the casing B can be fed downward from above, while the pair of crushing rollers S are close to each other. In parts, it is covered against gravity Since it is configured to allow breaking the grinds from below as entangle upward, it becomes an object to be crushed in the hopper C by the pair of feed rotor T allow and continuously fed at a constant in the casing B. In addition, when the load to be crushed by the pair of crushing rollers S increases, the rotation of the pair of feeding rotors T is stopped or slowed down so that the material to be crushed in the hopper C enters the casing B. Feeding can be stopped or delayed. That is, the object to be crushed is not fed into the casing B beyond the crushing ability of the pair of crushing rollers S, and the rotation of the pair of crushing rollers S is stopped or the crushing rollers S are worn out. Therefore, a constant and stable crushing process can be continuously maintained for a long time, and the material to be crushed can be efficiently crushed appropriately. In addition, the crushing apparatus has a simple structure, excellent durability, suitable for mass production, inexpensive and economical.
[0045]
In particular, the pair of crushing rollers S is directed from above to below so that the material to be crushed from the hopper C is along the peripheral body plate of the casing B in a portion between the peripheral body plate of the casing B and the crushing roller S. In the interference portion where the pair of crushing rollers S are close to each other, the object to be crushed is wound up from below to the upper side against gravity. Since it is configured so that it can be crushed, the object to be crushed is fed into the interference (center) portion where the pair of crushing rollers S are close to each other, and the pair of crushing rollers S are stopped by the biting of the object to be crushed. There will be no fear.
[0046]
In addition, the pair of feeding rotors T are rotated in such a direction that the objects to be crushed between the inner walls of the hopper C can be sequentially fed from the upper side to the lower side, and are then introduced into the hopper C. Since the objects to be crushed can be fed into the casing B, the objects to be crushed are collectively fed to the pair of crushing rollers S, and the drive rotation of the pair of crushing rollers S is stopped, or Thus, there is no fear that the load (crushing load) during driving rotation of the pair of crushing rollers S becomes extremely large.
