【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破砕できるようにした破砕システムに於いて、一次破砕によってある程度の大きさ以下に予め切断された多数の被破砕物を、二次破砕装置によって小さく破砕する際に、被破砕物の二次破砕装置への送給量や送給タイミング等を確実に且つ簡単にコントロールでき、しかも、被破砕物夫々の送給姿勢を確実に且つ簡単に揃えて送給でき、更に、各種被破砕物の寸法等に適した送給ドラムを簡単に互換装着できるように工夫した破砕システムに於ける被破砕物の送給装置に関するものである。
【０００２】
【従来の技術】
従来、この種の破砕システムにあっては、例えば、適宜被破砕物を一次破砕によってある程度の大きさ以下に予め切断し、この被破砕物を二次破砕装置によって小さく破砕するようにしている。そして、被破砕物の二次破砕装置での破砕は、例えば、多数の被破砕物をホッパー内に投入しておき、このホッパーから被破砕物を重力を利用して二次破砕装置に供給するようにしたものが多く提供されている。
【０００３】
【発明が解決しようとする課題】
ところが、前述の如き被破砕物の送給手段にあっては、ホッパーから被破砕物を二次破砕装置に供給するとき、二次破砕装置での破砕処理能力を超えた被破砕物が供給されてしまう難点があった。そのため、二次破砕装置での破砕処理能率が低下したり、二次破砕装置の回転切断刃等の損傷を招く等の問題点があった。
【０００４】
また、被破砕物が二次破砕装置に供給されるときに、被破砕物の供給姿勢が一定しておらず、回転切断刃等に対して切断し難い姿勢の侭供給される等の難点があった。
加えて、複数の被破砕物が二次破砕装置の上方でブリッジ状となってしまい、被破砕物を二次破砕装置にスムーズに供給できない等の難点もあった。
【０００５】
【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ると共に、被破砕物の二次破砕装置への送給量や、送給タイミング等を確実に且つ簡単にコントロールでき、また、被破砕物夫々の送給姿勢を確実に且つ簡単に揃えて送給でき、加えて、各種被破砕物の寸法等に対応させて送給ドラムＡを互換装着できると共に、その互換装着作業が簡単に行え、しかも、取扱いが容易で、構成簡素で、耐久性に優れ、量産に適し、低廉で、経済的な破砕システムに於ける被破砕物の送給装置を提供できるようにすべく創出されたものである。
【０００６】
しかして、本発明の送給装置にあっては、一次破砕装置によってある程度の大きさ以下に予め切断された適宜被破砕物を、その送給量や、送給タイミング等をコントロールすると共に、その送給姿勢を揃えて二次破砕装置に供給するための送給装置であって、上方に投入口が設けられ下方に送出口が設けられているケーシングＢと、このケーシングＢ内に駆動回転自在に且つ互換可能に装着される一対の送給ドラムＡと、この一対の送給ドラムＡ夫々に駆動回転力を与える適宜駆動手段Ｃとを備え、送給ドラムＡは、略円筒状のドラム基体１と、このドラム基体１の外周表面に突設される複数の送給突起２とを備え、一対の送給ドラムＡは、所定間隔隔てた状態で平行に且つ水平に配されると共に、相互の間にある空間部分に於いて、送給突起２が下方がわから上方がわに向って移動するような向きに夫々回転して、送給ドラムＡとケーシングＢの湾曲内壁面との間の空間部分を被破砕物が上方から下方に向って移動するように形成され、複数の送給突起２は、送給ドラムＡの円周方向に沿って略等間隔に配され、且つ送給ドラムＡの回転中心線に対して平行な方向に沿って略等間隔に配されて、被破砕物が複数の送給突起２の間に収まるように構成し、送給ドラムＡは、略円筒状に形成されるドラム基体１と、略丸棒状に形成されると共に、ドラム基体１の外周表面に略放射方向に突設される複数の送給突起２と、ドラム基体１の一端内部に設けられる略多角形筒状の軸係合凹部３と、ドラム基体１の他端内部に設けられる略円筒状の軸受部４とを備え、ケーシングＢの一方の側壁には、軸受部５を介して伝達軸６を回転自在に装着すると共に、伝達軸６の先端部分がケーシングＢ内に僅かに突出するように形成し、この伝達軸６は、その先端部分が送給ドラムＡの軸係合凹部３内に挿脱自在に嵌入可能で、その駆動回転力を送給ドラムＡに伝達できるように形成され、ケーシングＢの他方の側壁には、比較的大きな開口部９を設けると共に、この開口部９を開閉可能な開閉側板８を設け、この開閉側板８には、送給ドラムＡの軸受部４内に挿入可能で、送給ドラムＡの他端部を回転自在に支持可能な略短円柱状の支承軸７を突設し、開閉側板８は、開口部９を外がわから覆えるような形状を呈し、ケーシングＢに揺動自在に装着されると共に、ケーシングＢの開口部９周縁部分にネジ止め手段等によって固定できるよう形成され、支承軸７は、適宜ネジ止め手段を介して開閉側板８に着脱自在に固定すると共に、その背面部分に操作ハンドルを固着して構成する手段を採用した。
【０００７】
【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、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、適宜破砕装置で小さく破砕できるようにした破砕システムに於いて、一次破砕装置によって所望の大きさ以下に予め切断された被破砕物を、その送給量や、送給タイミング等をコントロールできるようにして二次破砕装置に送給し、二次破砕装置での破砕作業が能率良く行えるようにした送給装置である。しかも、被破砕物夫々の送給姿勢が揃えられるようにして送給でき、また、被破砕物の寸法等に対応した送給も可能となるように構成したものである。
【０００８】
そして、この送給装置は、ホッパー１０による投入口が上方に設けられ、且つコンベヤ１６（或いは、二次破砕装置）の上方に位置する送出口が下方に設けられている略矩形枠状のケーシングＢと、このケーシングＢ内に駆動回転自在に且つ互換可能に装着される一対の略平行な送給ドラムＡと、この一対の送給ドラムＡ夫々に駆動回転力を与える適宜駆動手段Ｃとを備えたものである。

【００１５】
また、ケーシングＢの他方の側壁には、比較的大きな適宜開口部９を設けると共に、この開口部９を開閉可能な開閉側板８を設け、しかも、この開閉側板８には、送給ドラムＡの軸受部４内に挿入可能で、送給ドラムＡの他端部を回転自在に支持可能な略短円柱状の支承軸７を突設してある。
【００１６】
前記開閉側板８は、開口部９を外がわから覆えるような形状を呈し、例えば、適宜ヒンジ手段等を介してケーシングＢに揺動自在に装着され、ケーシングＢの開口部９周縁部分にネジ止め手段等によって、固定できるよう構成されている。すなわち、ネジ止め手段を取外すことで、開口部９を開閉できるようになる。
【００１７】
前記支承軸７は、適宜ネジ止め手段を介して開閉側板８に着脱自在に固定されており、その背面部分には、操作ハンドルが固着されて、支承軸７自身の着脱が行い易くなるように形成してある。すなわち、送給ドラムＡを互換装着する際に、支承軸７を開閉側板８から取外し、開閉側板８を揺動させて、開口部９を開口状態としてから、開口部９がわに送給ドラムＡを引出せるように構成されている。ところで、支承軸７は、適宜潤滑材が供給できるように形成されており、送給ドラムＡの軸受部４との摩擦を低減できるように形成されている。
【００１８】
駆動手段Ｃは、例えば、適宜駆動モーターの回転力を適宜歯車を介して一対の送給ドラムＡに伝達でき、一対の送給ドラムＡを同期回転せしめられるように構成されている。しかも、駆動モーターの回転速度を制御可能で、一対の送給ドラムＡの回転速度を自由にコントロールできるよう構成されている。
