また、上記構成において、前記切替手段(95)は、前記車体フレーム(51)に中間部を支点にして車軸方向に回動自在に支持されるとともに先端部に前記従動ギヤ(93)が連結され、車軸方向の回動により前記従動ギヤ(93)を摺動させる操作レバー(100)を備えるようにしてもよい。この構成によれば、簡易な構造で、従動ギヤを動かしてモード切替を行うことができる。
また、上記構成において、前記従動ギヤ(93)は、前記駆動ギヤ(92)及び前記係合片(94)の一方に噛合した後、その状態を保持したまま他方に噛合するようにしてもよい。この構成によれば、従動ギヤを駆動ギヤ及び係合片により容易かつ迅速に噛合させることができる。
また、車体フレームに車軸と平行に設けられるクラッチパイプと、クラッチパイプに摺動自在に設けられ、駆動ギヤと噛合/非噛合する従動ギヤと、ドラム式ふるい体の外周に設けられ、従動ギヤが駆動ギヤと噛合した位置で従動ギヤと噛合する係合片とを有し、従動ギヤを駆動ギヤと噛合/非噛合する位置へ摺動させることで、自動回転モードと、従動ギヤを駆動ギヤと噛合する位置から待避させ、手動回転モードとに切り替えるようにすれば、簡易な構造で、状況に応じたゴミ分別作業が可能になる。
また、ドラム式ふるい体は、車軸の上方で、このドラム式ふるい体(の回転中心が車軸と前後方向にずれた位置に配置され、従動ギヤの回転中心は、側面視で、ドラム式ふるい体の回転中心と車軸との間に設けられるようにすれば、ドラム式ふるい体と車軸との間の空きスペースを利用して従動ギヤを配置でき、ゴミ分別回収機を上下方向にコンパクト化できる。
また、操作レバーの操作に応じてクラッチパイプを摺動する摺動部材を有し、この摺動部材と従動ギヤとの間に、従動ギヤを噛合する位置へ向けて付勢する付勢部材を設けるようにすれば、従動ギヤを噛合させる際、従動ギヤの位相が合った際に付勢力によって迅速かつ容易に噛合させることができる。
また、車体フレームは、前端にトレーラヒッチに取り付けられるジョイントを有し、このジョイントから、車体の幅中心を通り後方へ直線状に延びた後に後下方へ延び、その後端に車軸を支持するメインフレームと、メインフレーム上方に支持され、ドラム式ふるい体をローラーを介して回転自在に支持するふるい体支持枠と、ふるい体支持枠に支持され、ドラム式ふるい体の周囲を覆うシールド体とを備えるようにすれば、コンパクトなフレーム構造でゴミ分別回収機を構成することができる。
また、支持フレームは、メインフレームの後端から上方に延びてふるい体支持枠を支持する後方支持フレームを有し、従動ギヤは、前方支持フレームの後方、かつ、後方支持フレームの前方に配置されるようにすれば、前方支持フレームと後方支持フレームとによって従動ギヤの前後をガードすることができる。
<第1実施形態>
図1は、第1実施形態に係るビーチクリーン用ゴミ分別回収機の牽引状態を左側方から見た図である。
この図に示すように、ビーチクリーン用ゴミ分別回収機(以下、ゴミ分別回収機と言う)50は、車両1で牽引可能な牽引型に構成されている。
車両1は、ビーチ等の砂地での走行に適した小型車両であり、小型軽量に構成された車体の前後に、比較的大径の低圧バルーンタイヤである左右の前輪2及び後輪3を備え、最低地上高を大きく確保して主に不整地での走破性を高めた所謂ATV(All Terrain Vehicle)として構成される。車両1の車体フレーム4は、車幅方向中央部において前後に長いボックス構造を形成し、該車体フレーム4の略中央部には、車両1の原動機としてのエンジン5が搭載される。
ここで、車両1は前記変速機のギヤ比を電動により変更可能な所謂セミオート車両であり、例えば遠心クラッチを介することで、クラッチ操作を行わずにチェンジボタン等の操作のみで前記ギヤ比を変更可能である。このような車両1は、ベルト式の変速機を備えた車両と比べて、走行負荷が大きい走行や一定速度での走行にも好適である。
なお、車両1は、セミオート車両に限定されるものではなく、例えば、ギヤ比の変更を自動化したオートマチックトランスミッション車両でもよい。
なお、図中、符号12aは、車体フレーム4前部に支持されるフロントキャリアを示し、符号12bは、車体フレーム4後部に支持されるリアキャリアを示している。
図2は、ゴミ分別回収機50を後方から見た斜視図であり、図3は下方から見た図であり、図4は、右側方から見た図であり、図5は、ごみ分別回収機50を車輪53を外して左側方から見た斜視図である。なお、図3中、符号C1は、ゴミ分別回収機50の幅中心を示し、符号LAは、ドラム式ふるい体54の軸線(回転中心)を示し、符号LBは、車軸52の軸線(回転中心)を示している。
図1に示すように、ゴミ分別回収機50は、車両1に牽引される車体フレーム51と、車体フレーム51に車軸52(図2参照)を介して取り付けられる左右一対の車輪53と、車体フレーム51に取り付けられるドラム式ふるい体54とを備えており、公知のビーチクリーナで回収されたゴミから砂を分離する移動式の砂分離装置として機能する装置である。
ゴミ分別回収機50の車体フレーム51の前端部には、トレーラヒッチ11に取り付け可能なジョイント(ヒッチカプラとも称する)55が設けられ、このジョイント55を介して車両の後部に設けられたトレーラヒッチ11に連結され、該車両1によりゴミ分別回収機50を牽引可能に構成される。
メインフレーム61は、図1に示すように、側面視で、ジョイント55から後方へ直線状に延出する前方部61Aと、前方部61Aの後端から後下方へ直線状に延びる後方部61Bとを有し、図3に示すように、平面視では、前方部61Aと後方部61Bとが車体の幅中心C1を直線状に延出するように形成される。この前方部61Aと後方部61Bとは、単一の金属製パイプを屈曲することによって一体に形成されている。
前方部61Aは、後方部61Bよりも数倍程度長く形成され、このメインフレーム61上方に支持されるふるい体支持枠62よりも前方に長く延在する。この前方部61Aのジョイント55近傍には、下方に延びる逆T字状のスタンド61Cが設けられ、このスタンド61Cは、ジョイント55を車両1から取り外している場合に、地面に当接してメインフレーム61を地面から浮かした状態に支持する。
この車軸52は、左右の車輪53と一体回転する車軸である。このため、ゴミ分別回収機50が車両1に牽引された場合には、車輪53の回転に合わせて車軸52が同一の回転数で回転する。
図4及び図5に示すように、支持フレーム65は、車軸52よりも前方に設けられる前方支持フレーム66と、車軸52よりも後方に設けられる後方支持フレーム67とを有し、前方支持フレーム66は、メインフレーム61の前方部61Aの後部から上方に延びる複数(本構成では3本)のフレーム部材で構成され、これら前方支持フレーム66により、ふるい体支持枠62の前部がメインフレーム61に支持される。
本構成では、この前後の支持フレーム66,67によって、ふるい体支持枠62を左右の車輪53よりも上方に支持している。この場合、このふるい体支持枠62の上下位置は、左右の車輪53の上縁に近接する位置とされる。これにより、ふるい体支持枠62を車輪53との干渉を避けつつ低い位置に設け、ドラム式ふるい体54を作業性に優れた低い位置に設けるようにしている。
なお、図4中、符号68は、メインフレーム61の後方部61Bと後方支持フレーム67の下端との間を架橋するガセットであり、このガセット68によって、メインフレーム61、車軸支持体61D及び後方支持フレーム67の連結強度を向上させている。
この左右一対の前後延出フレーム62Aの前後端には、上下方向に延びる筒状部材62Cが接合され、これによって、ふるい体支持枠62の前後左右に存在する4つの角部には、上下方向に延びる金属製の筒状部材62Cが配置される。この筒状部材62Cには、上方からシールド体63の一部が入り、シールド体63をふるい体支持枠62に位置決めする。
この場合、図4に示すように、前後のガイドローラー71は、ドラム式ふるい体54の下部を前後から挟むように配置され、前後のガイドローラー71によってドラム式ふるい体54の前後移動を規制し、ドラム式ふるい体54を安定して支持することができる。なお、ドラム式ふるい体54は、ガイドローラー71に載置されるだけなので、ドラム式ふるい体54を持ち上げればドラム式ふるい体54を容易に着脱可能である。
このドラム式ふるい体54は、一端側(本構成では左側)が開口し、他端側(右側)が底部54Aで閉塞される有底円筒の骨格部を形成する金属製のふるい本体81と、このふるい本体81の周囲を覆う金属製の網部材82とを備えている。
これら筒部81A~81Cは、ドラム式ふるい体54の軸線LA方向に延びる金属鋼管或いは金属棒で形成された複数の軸方向延長ロッド84で連結され、この軸方向延長ロッド84は、周方向に間隔を空けて多数設けられている。そして、この軸方向延長ロッド84の外側から、ふるい本体81の外周を覆うように網部材82が取り付けられる。
図4及び図5に示すように、閉塞側筒部81Bには、この閉塞側筒部81Bの開口を囲うように金属鋼管或いは金属棒部を格子状に組んだ格子部85が設けられ、この格子部85の開口を覆うように外側から金属製の網部材86が取り付けられ、これら格子部85及び網部材86によって、ドラム式ふるい体54の底部54Aが形成される。
また、軸方向延長ロッド84及び格子部85は、網部材82,86の内側に位置してふるい本体81の内側に突出する部材であるため、これら部材84,85を、ドラム式ふるい体54内に投入された砂の塊を粉砕する砂粉砕体としても機能させることができる。
側方シールド部材63Aは、金属パイプをU字状に曲げ、その両端部が、ふるい体支持枠62の左右に位置する前後一対の筒状部材62Cに上方から挿入されることによって、ふるい体支持枠62に連結される。
また、周囲シールド部材63Bは、金属パイプを用いて、左右一対の側方シールド部材63Aの前部間、上部間及び後部間を架橋し、ドラム式ふるい体54の前方、上方及び後方を覆う。また、この周囲シールド部材63Bは、左右一対の側方シールド部材63Aを補強するクロスメンバーとしても機能する。
このため、この扉部材63Dによって、ドラム式ふるい体54の開口側から車外へのゴミの飛び出しを規制するとともに、この扉部材63Dを開くことによって、ドラム式ふるい体54内へ回収した砂混じりのゴミを投入することができる。なお、図2及び図5中、符号63Fは、扉部材63Dに設けられる把手である。
また、各図では、シールド体63が骨格構造だけで形成される場合を示しているが、このシールド体63の外周全体を網部材等の覆い部材で覆い、ドラム式ふるい体54からの砂の飛散をシールド体63で抑制する構成にしてもよい。
また、本構成のゴミ分別回収機50は、このドラム式ふるい体54を車輪53の回転力で回転させる自動回転モードと、車輪53の回転力から切り離して手動回転自在にする手動回転モードとに切り替える機構部(伝達機構)91を具備している。このため、車両1で牽引可能な整地された場所では、自動回転モードに設定すれば、車両1の牽引力でゴミの分別回収作業ができ、車両1で牽引し難い不整地では、手動回転モードに設定することによって人力で容易にゴミの分別回収作業ができるようになっている。
以下、この機構部91及び周辺構造について説明する。
図6及び図7に示すように、機構部91は、車軸52に取り付けられる駆動ギヤ92と、車体フレーム51に取り付けられ、駆動ギヤ92と噛合/非噛合可能に設けられる従動ギヤ93と、ドラム式ふるい体54に設けられ、従動ギヤ93が駆動ギヤ92と噛合した位置で従動ギヤ93と噛合する係合片94と、従動ギヤ93を摺動させてギヤ位置を変更するギヤ切替機構(切替手段)95とを備えている。
詳述すると、この駆動ギヤ92は、車軸支持体61Dの左端近傍位置にて車軸52を中心にして拡径する金属製の円板部92Aと、駆動ギヤ92周方向である円板部92A周方向に間隔を空けて円板部92A外周から車軸52の軸方向(右側)に延びる複数の棒状部材92Bとを備える。この棒状部材92Bは、同一の真円断面で軸方向に棒状に延び、その先端が車体の幅中心C1近傍に位置する。これによって、駆動ギヤ92の重心を車体の幅中心C1に近づけることができる。
なお、棒状部材92Bは、金属部材でもよいし、ゴム等の弾性部材で形成してもよい。弾性部材で形成すれば、駆動ギヤ92と従動ギヤ93との当接力を緩和させることが可能である。
ここで、駆動ギヤ92と非噛合の状態とは、従動ギヤ93が棒状部材92Bの自由端側へ移動して、棒状部材92Bの位置から完全に待避した位置に移動した状態を言い、図7では、この場合の駆動ギヤ92を二点鎖線で示している。
図5及び図6に示すように、クラッチパイプ96は、車軸52と平行に直線状に延びる金属製のパイプであって、従動ギヤ93を上記2位置(噛合位置と非噛合位置(或いは待避位置))へ摺動可能な長さを有し、左右一対の支持フレーム97を介して車体フレーム51に支持される。
より具体的には、従動ギヤ93の歯部93Aは、側面視で、その基端側が径方向外側にいくに従って徐々に幅広となり、径方向外側の先端側が、径方向外側にいくに従って徐々に幅狭となり、つまり、先細形状に形成されている。
この構成によれば、従動ギヤ93及び駆動ギヤ92に砂が付着した状態であっても、従動ギヤ93と駆動ギヤ92とを容易かつ確実に噛合させることが可能で、かつ、砂を落としやすくすることができる。
なお、図7中、符号94Cは、棒状部材94Bの外周を巻回するように装着されるゴム等の弾性部材であり、この弾性部材94Cにより、係合片94と従動ギヤ93との当接力が緩和されるようになっている。
この場合、図6に示すように、従動ギヤ93の下端に位置する歯部93Aが、駆動ギヤ92の隣り合う棒状部材92Bの間に入り、従動ギヤ93の上端に位置する歯部93Aが、隣り合う係合片94(棒状部材94B)の間に入り、車輪53の回転で駆動ギヤ92が回転すると、従動ギヤ93を介してドラム式ふるい体54が回転駆動される。
しかも、上記したように、従動ギヤ93の歯部93Aは、先細形状に形成されているので、隣り合う歯部93Aの先端間に空く隙間を広くでき、この隙間に係合片94が入りやすく、従動ギヤ93と係合片94を噛合し易く、砂が付着しても容易に噛合させることができる。
このため、ドラム式ふるい体54と車軸52との間の空きスペースを利用して従動ギヤ93を配置することができ、機構部91をコンパクトに配置できるとともに、ドラム式ふるい体54、従動ギヤ93及び車軸52を、上下方向に垂直に並べて配置する場合に比して、上下方向にコンパクトに配置できる。
さらに、本構成のレイアウトでは、図6に示すように、従動ギヤ93の前下方にメインフレーム61の後方部61Bが位置し、後下方に後方支持フレーム97が位置するので、既存のフレーム部材を用いて従動ギヤ93を下方からガードすることができる。また、従動ギヤ93の前方には、前方支持フレーム66が位置し、従動ギヤ93の後方には、後方支持フレーム97が位置するので、これら支持フレーム66,67によって従動ギヤ93の前後をガードすることができる。
図8は、ギヤ切替機構95を周辺構成とともに後上方から見た図であり、図9は、下方から見た図である。
図8及び図9に示すように、ギヤ切替機構95は、従動ギヤ93をクラッチパイプ96の軸方向に摺動させる操作レバー100を有している。図9に示すように、操作レバー100は、平面視で、略Z形状に屈曲する金属パイプで形成され、その先端部101が、従動ギヤ93と一体の筒部93Cに連結され、その中間部102が、クラッチパイプ96を支持する左右一対の支持フレーム97間を架橋するクロスプレート111に連結され、基端部103が、下方に屈曲して作業者が把持する把持部に形成されている。
このため、図9に示すように、操作レバー100を左右に回動させれば、従動ギヤ93を、駆動ギヤ92に噛合する位置(実線で示す位置)と、噛合しない位置(非噛合位置,二点鎖線で示す位置)とに移動させることができる。
なお、図8及び図9には、従動ギヤ93を駆動ギヤ92に噛合する位置に移動した場合の従動ギヤ93及び操作レバー100を実線で示し、従動ギヤ93を非噛合位置に移動した場合の従動ギヤ93及び操作レバー100を二点鎖線で示している。
このゲート部材122の係合溝121は、図7に示すように、左右に間隔を空けて下方に延びる左右一対の深溝部121A,121Bと、左右一対の深溝部121A,121Bよりも浅い溝であって、これら深溝部121A,121Bの上半部間を左右につなぐ浅溝部121Cとを有し、左右一対の深溝部121A,121Bのうち、一方側(右側)の深溝部121Bは、従動ギヤ93を駆動ギヤ92に噛合する位置に移動したときの操作レバー100が嵌る溝に形成され、他方側(左側)の深溝部121Aは、従動ギヤ93を非噛合位置に移動したときの操作レバー100が嵌る溝に形成されている。
操作レバー100が深溝部121A,121Bの最深部に操作されると、操作レバー100の左右への移動が規制されるため、操作レバー100を、噛合位置或いは非噛合位置に保持させることができる。これにより、操作レバー100を、ドラム式ふるい体54を車両1の回転力で回転させる自動回転モードの位置と、ドラム式ふるい体を車両の回転力から切り離し、手動回転自在にする手動回転モードの位置とに容易に切り替え、かつ、その位置に保持させることができる。これにより、操作レバー100は、自動回転モードと手動回転モードとに動作モードを切り替える切替レバーとして機能する。
この構成によれば、ギヤ切替機構95によって従動ギヤ93を駆動ギヤ92と噛合する位置へ摺動させれば、車輪53の回転力でドラム式ふるい体54を回転駆動させる自動回転モードに切り替えることができ、また、ギヤ切替機構95で従動ギヤ93を駆動ギヤ92と噛合する位置から待避させれば、ドラム式ふるい体54を手動回転できる手動回転モードに切り替えることができる。
しかも、このドラム式ふるい体54を回転させる機構部91が、車軸52に設けられる駆動ギヤ92と、車軸52に平行に設けられるクラッチパイプ96に摺動自在に設けられる従動ギヤ93と、ドラム式ふるい体54の外周に設けられる係合片94とで構成されるので、簡易な噛合構造にすることができ、機構部91の小型化を図り、ゴミ分別回収機50の小型化が可能になる。従って、簡易な構造で、機動性があり、不整地である海岸を移動しながらゴミを回収し分別することができ、モード切替によって状況に応じたゴミ分別作業が可能なゴミ分別回収機50を提供することができる。
また、ギヤ切替機構95は、車体フレーム51に中間部102を支点にして車軸方向に回動自在に支持されるとともに先端部101に従動ギヤ93が連結され、車軸方向の回動により従動ギヤ93を摺動させる操作レバー100を備えるので、単一の操作レバー100を用いた簡易な構造で、従動ギヤ93を動かしてモード切替を行うことができる。
さらに、上記支持フレーム65は、メインフレーム61の後端から上方に延びてふるい体支持枠62を支持する後方支持フレーム67を有し、従動ギヤ93は、前方支持フレーム66の後方、かつ、後方支持フレーム67の前方に配置されるので、これら支持フレーム66,67によって従動ギヤ93の前後をガードすることができる。
図10は、第2実施形態に係るゴミ分別回収機50のギヤ切替機構95を示している。図中、第1実施形態とほぼ同一の部材は同一の符号を付して示している。
図10に示すように、クラッチパイプ96には、従動ギヤ93を保持する筒状のギヤ保持体151と、操作レバー100が連結される筒状のカラー(摺動部材)161とが設けられている。
ギヤ保持体151は、金属製又は樹脂製の略円筒部品に形成され、その貫通孔151Aにクラッチパイプ96が挿通されることにより、クラッチパイプ96に摺動自在、かつ、回転自在に設けられる。
このギヤ保持体151の一端部(図10中、左側の端部)151Lと他端部(図10中、右側の端部)151Rとの間には、径方向外側に環状に突出する単一のつば部151Bが設けられており、このつば部151Bを基準にして、一端部151Lの外周面に、従動ギヤ93が固定され、他端部151Rの外周面に、カラー161が摺動自在かつ回転自在に設けられる。
また、ギヤ保持体151とクラッチパイプ96との間には、軸方向に間隔を空けて一対のシール材173,174が配置され、これらシール材173,174により、ギヤ保持体151とクラッチパイプ96との間の隙間に外部から砂等が進入する事態が防止される。
図10に示すように、このカラー161の内径は、ギヤ保持体151の他端部151Rの外径と略同じ長さに形成され、このカラー161の外径は、つば部151Bの外径と略同じ長さに形成される。このため、カラー161は、つば部151Bと、他端部151Rに設けた止め輪172との間の範囲を、他端部151Rの外周面に沿って摺動自在かつ回転自在となっており、つまり、カラー161は、クラッチパイプ96に沿って摺動自在かつ回転自在に配置される。
本構成では、このカラー151とつば部151Bとの間にコイルスプリング(付勢部材)175が介挿されており、上記カラー151の摺動方向への動き(クラッチパイプ96軸方向の動き)が、コイルスプリング175を介してつば部151Bに伝達され、つば部151Bと一体のギヤ保持体151を移動させる。つまり、操作レバー100の操作が、コイルスプリング175を介してギヤ保持体151に伝達される。なお、図中、符号LGは、クラッチパイプ96の軸線を示している。
この撓み量は、カラー161の移動量に比例するので、この撓みで生じるコイルスプリング175の付勢力がギヤ保持体151を移動可能な力に達すると、ギヤ保持体151が、カラー161と同方向に移動し、従動ギヤ93が、ドラム式ふるい体54の係合片94及び駆動ギヤ92と噛合する位置(図10に示す、噛合位置β,γ)へと向かって移動する。
このため、従動ギヤ93は、レバー操作から時間差を伴って、コイルスプリング175の付勢力によって噛合位置β,γへと移動する。
なお、噛合位置βは、ドラム式ふるい体54の係合片94に噛合し、駆動ギヤ92には噛合しない位置(第1噛合位置)を示し、噛合位置γは、ドラム式ふるい体54の係合片94及び駆動ギヤ92に噛合する位置(第2噛合位置)を示している。
しかし、レバー操作のタイミングで、従動ギヤ93と、ドラム式ふるい体54の係合片94と駆動ギヤ92との3部品が互いに噛合できる回転位置(位相)に揃っていることは通常、希であり、レバー操作のタイミング調整だけで、従動ギヤ93を、ドラム式ふるい体54の係合片94及び駆動ギヤ92の各々と噛合させることは難しい。
特に、本構成では、従動ギヤ94を、係合片94や駆動ギヤ92と回転同期させる機構を設けていないシンプルな構造であるため、各部品を互いに噛合させることがより難しい構成である。
このため、レバー操作のタイミングに依存することなく、操作レバー100を仮想線(二点鎖線)で示す位置に固定しておけば、位相が揃ったタイミングになると、直ちに従動ギヤ93を作動させて噛合させることが可能になる。
このため、従動ギヤ93は、非噛合位置αから図10中、左方向へ移動すると、まず、ドラム式ふるい体54の係合片94と噛合できるまで(位相が揃うまで)、係合片94の側面に当接した状態で待機し、位相が合ったタイミングでコイルスプリング175の付勢力により直ちに噛合し(第1噛合位置β)、次に、駆動ギヤ92と噛合できるまで(位相が揃うまで)駆動ギヤ92の側面に当接した状態で待機し、位相が合ったタイミングでコイルスプリング175の付勢力により直ちに噛合する(第2噛合位置γ)。
このため、従動ギヤ93が時間差を持って駆動ギヤ92と係合片94と噛み合い、同じタイミングで両部材(係合片94及び駆動ギヤ92)に噛み合う場合に比して、噛み合い易くすることができ、より容易かつ迅速に噛合させることが可能になる。
従って、車輪53を回転させた状態で自動回転モードと手動回転モードとの間の切り換えを容易かつ迅速に行うことが可能になる。なお、コイルスプリング175に代えて、他の付勢部材を用いてもよい。
さらに、この操作レバー100と従動ギヤ93とを連結する連結機構を、上記カラー161と、コイルスプリング175と、従動ギヤ93を保持する筒状のギヤ保持体151とで構成したので、部品点数が少なく、かつ、上記3部品がクラッチパイプ96に挿通される挿通部品であるため、クラッチパイプ96からの張り出し量が小さく、全体を小型化することができる。
例えば、上記実施形態では、ドラム式ふるい体54の回転中心(軸線LA)を、車軸52よりも前方にずれた位置に配置し、従動ギヤ93の回転中心(LC)を、ドラム式ふるい体54の回転中心(軸線LA)と車軸52との間に設ける場合を説明したが、これに限らず、ドラム式ふるい体54の回転中心(軸線LA)を、車軸52よりも後方にずれた位置に配置し、従動ギヤ93の回転中心(LC)を、ドラム式ふるい体54の回転中心(軸線LA)と車軸52との間に設けてもよい。この場合でも、ドラム式ふるい体54、従動ギヤ93及び車軸52を上下方向に垂直に並べて配置する場合に比して、ゴミ分別回収機50を上下方向にコンパクト化できる。
また、上記実施形態では、ドラム式ふるい体54の係合片94をU字状にする場合を説明したが、これに限らない。例えば、図11に示すように、ドラム式ふるい体54の左端近傍位置にてドラム式ふるい体54の回転軸を中心にして拡径する金属製の円板部194Aを設け、この円板部194の周方向に間隔を空けて円板部194A外周から回転軸の軸方向(右側)に延びる複数の棒状部材194Bを設けるようにしてもよい。この構成によれば、棒状部材194Bから砂が落ち易く、従動ギヤ93と棒状部材194Bとの噛合部に砂が滞留し難くなり、摩耗を抑制することができる。
また、上記実施形態では、図1に示すゴミ分別回収機50に本発明を適用する場合について説明したが、これに限らず、砂とゴミを分別するビーチクリーン用ゴミ分別回収機50に広く適用可能である。なお、このゴミ分別回収機50は、ビーチ以外の場所で用いてもよいことは勿論である。
