Description

【０００１】
【発明の属する技術分野】
この発明は、堆肥の積込機能を有するマニュアスプレッダーに関するものである。
【０００２】
【従来の技術】
堆肥の積込機能を有するマニュアスプレッダーとしては、本願出願人が開発した技術が特開平８−７０６３１号、特開平１１−３４６５０８号公報等に開示されてる。
【０００３】
【発明が解決しようとする課題】
堆肥の散布を行うマニュアスプレッダーに堆肥の積込機能を合わせて設けるには、荷箱底部に設けるコンベアの終端に水平軸回りに回転する所謂横型ビータを横架し、この横型ビータとコンベアを正逆転させて行う場合が多い、しかしながらこの横型ビータは積込性能は優れているが、広幅散布は困難な為、特に数ｍの散布幅が必要な大圃場等で使用される大型機械には特開平１１−３４６５０８号公報に開示されている如く、散布専用のスピナー（ディスク型ビータ）を横型ビータの下方に配置し、該横型ビータにより繰出される堆肥を垂直軸回りに回転するスピナーで受けその跳出翼で広く散布する。この場合、堆肥の積込の際にはスピナーが支障となる為、上方に退避収納する必要がある。
この発明は、横型ビータによる積込機能を有するマニュアスプレッダーにおいて、スピナー等の複雑な装置を設けることなく散布幅を横型ビータの幅よりも広くして作業性を向上させようとするものである。
【０００４】
【課題を解決するための手段】
荷箱１の底部に設けるコンベア２と荷箱１の開放側に取着のビータ枠３に横架する横型ビータ４とを正逆転させ堆肥の積込みと散布を可能に構成し、ビータ枠３の両側板６，６上部には開口７，７と該開口７，７を閉鎖する位置と該開口７，７を開放し放出される堆肥を前側方へ案内する位置とに切替自在の散布案内板８，８を設けるとともに、ビータ軸５には複数の平板状の羽根２６，２６を、積込回転方向イにおいて掬い角αを形成すべく傾斜して取着し、少なくとも両側板６，６側に位置する羽根２６の散布回転方向ロ後方側に跳出翼２８を延設し更に該跳出翼２８部を外側方へ向け所定角度β屈曲させてなる積込散布兼用マニュアスプレッダ−の構成とする。
又、ビータ軸５に取着する複数枚の平板状の羽根２６，２６を２枚一組とし相対向させてなる請求項１記載の積込散布兼用マニュアスプレッダーの構成とする。
【０００５】
【発明の作用及び効果】
堆肥の積込時にあっては、ビータ枠３の両側板６，６上部に設ける開口７，７を散布案内板８，８で閉鎖することにより横型ビータ３で掻込まれる堆肥をフラットに形成される該両側板６，６で円滑に案内し、取込み方向に回転するコンベア２へ引継ぎ荷箱１内へ積込むことができる。
堆肥の散布時にはコンベア２を送出し方向へ回転させ、又、横型ビータ３を散布回転方向ロへ回転させるとともに、両側板６，６に設ける散布案内板８，８を操作し開口７，７を開放する。
コンベア２で繰出される堆肥は、横型ビータ４に取着した積込回転方向（イ）において掬い角（α）を形成すべく傾斜した羽根２６，２６により前方へ向け跳出し散布されるが、少なくとも両側板６，６側に位置する羽根２６，２６の散布回転方向ロ後方側に外側方へ向け所定角度β屈曲延出する跳出翼２８を設けてあり、この跳出翼２８の作用を受ける堆肥は強力に両外側へ跳出され両側板６，６の開口７，７から散布案内板８，８の案内を受けて拡散散布される。
又、請求項２の発明にあっては、ビータ軸５に取着する複数枚の平板状の羽根２６，２６を２枚一組として対向させるものであるから、請求項１の作用効果に加えて、相対向する羽根２６，２６によって掻込みを確実に行うことができる。
【０００６】
【発明の実施の形態】
図例は歩行型のマニュアスプレッダーを示し、車台１０の両側にはクローラ型走行装置１１，１１を装備し、車台１０の後部には中央に操縦枠１２をその一側には原動機１３を搭載してある。操縦枠１２には走行クラッチレバー１４、前後進切替レバー１５、サイドクラッチレバー１６，１６、把手１７等を設けてある。
車台１０の前側には両側枠１８，１８と後枠１９とからなり前側を開放する荷箱１を搭載し、該荷箱１の底部には平ベルト状のコンベア２を車台１０前後に架設のローラ２０，２０間に掛回してある。２１は案内板であり、コンベア２の裏面を摺接案内する。
荷箱１の開放側、即ち、前端側には左右の両側板６，６と覆板２２とから構成されるビータ枠３を取着し、その両側板６，６間に横型ビータ４を回転自在に軸支してある。
このビータ枠３は、荷箱１の側枠１８高さよりも高く構成して、横型ビータ４上方に堆肥の上側積込口兼散布口２３を形成し、又、覆板２２は荷箱１上方まで延出し、操縦者側への堆肥の飛散防止板としての機能を持たせてある。
２４は掬上板であり、コンベア２直前の側枠１８，１８間に取着し、上側の横型ビータ４との間に堆肥の下側積込口兼散布口２５を形成する。
【０００７】
該横型ビータ４の軸５には、積込機能と散布機能とを合せて有する多数の羽根２６，２６を取着してある。該羽根２６，２６は平板材で構成され、その先端側を手の如く幅広で、かつ堆肥切崩し用の複数の突起２７，２７を設けてあり、更に突起２７，２７先端を結ぶ線が略円弧状となるよう設けてある。
該羽根２６，２６は、ビータ軸５の周方向同角度位置で軸方向に隣接する２枚を一組Ａとし、積込回転方向イにおいて、相対向して掬い角αを形成すべくビータ軸５に傾斜して取着してある。
この各組の羽根２６，２６は、側板６側を第１組とすると、隣接の第２組は軸５の周方向に１８０度位相を異ならせ、又、軸５方向には上記第１組の羽根２６，２６の中間対応位置から同ピッチで羽根２６，２６を取着してある。
この第１組及び第２組の羽根２６，２６を第１群とすると、隣接する第２群においては、第１群全体をそのまま軸５の周方向に９０度位相を異ならせ、又、軸５方向には第１群と所定の間隔をおいて設けてある。
この第１群及び第２群の羽根２６，２６は他側の側板６側からも対称的に配置し、中央には第３群の羽根２６，２６を配設してビータ４を構成してある。
【０００８】
又、両側板６，６に接近する羽根２６，２６は、堆肥の積込時等側板６との摩擦抵抗が大きい為、他の羽根２６が４．５ｍｍであるに対し６ｍｍと板厚を厚くしてある。
上記した第１群と第２群の８枚４組の羽根２６，２６のうち、各組とも側板６側に位置する４枚の羽根２６、２６の先端部には、下記の如き跳出翼２８を設けてある。即ち、該４枚の羽根２６，２６先端部の散布回転方向ロ後方側には各突起２７，２７の先端を結ぶ円弧線に略連続して跳出翼２８を設けてあり、該跳出翼２８は、外側方へ向け所定角度β、具体的には約２０度屈曲させ跳出面２９としてある。なお、跳出翼２８を突起２７，２７を結ぶ円弧線より突出させると堆肥との抵抗が大きくなる。
この屈曲角度は、大きい程堆肥を側方遠くまで散布可能であるが、堆肥積込時の抵抗となる為、跳出翼２８の面積にもよるが、この程度が望ましい。又、各組の相対向する羽根２６，２６の掬取り角は約４０度である。
前述の通りビータ枠３の両側板６，６間には横型ビータ４を軸支してあるが、該両側板６，６のビータ軸５軸支部上方の散布方向側部分と散布方向後方側部分とに亘って開口７，７を設けてある。即ち、両側板６，６のビータ軸５の軸支部よりも上方の覆板２２までの高さで、側板６の前後方向略全長に亘って、且つ、散布方向端を開放する開口７，７を設けてある。
【０００９】
散布案内板８，８は、該開口７の後部に回動自在に支承される上下軸３０に取着され、該開口７を完全に閉鎖する姿勢と、両外側方へ約６０度回動され開口７を開放するとともに、放出される堆肥を前側方へ案内する姿勢とに回動切替可能に構成してある。３１，３１はその操作レバーであり、ワイヤーを介して操作ボックス３２の上下軸３０の作動機構（図示せず）と連結してある。又、操作ボックス３２は覆板２２上に配設され、ビータ枠３の補強部材としての機能を有する。
第７図に示すものは、散布案内板８，８の上部に飛散規制板９を設けたものを示し、散布案内板８，８上部にボルト３３止めしてある。該飛散規制板９は、散布案内板８と同じ前後長さを有し、ビータ枠３の覆板２２よりも若干上方にまで延設される立板３５と、該立板３５から内方に向け折曲形成される天板３６とから構成される。又、天板３６の前縁は内側に向け円弧状に形成してある。
【００１０】
又、３７は伝動ケースであり、横型ビータ４への伝動機構を内装してある。３８は油圧シリンダーであり、車台１０と荷箱１間に設けられ、油圧レバー３９の操作により荷箱１を水平位置と前方が下降傾斜する積込位置とに昇降可能に構成してある。４０は作業レバーであり、横型ビータ４とコンベア２の回転方向を切替操作するものである。
堆肥の積込を行う場合には、横型ビータ４を積込み方向イへ回転させ、又、コンベア２を取込み方向に回転させるとともに、油圧シリンダー３８を作動させ荷箱１前方側を下降させ掬上板２４を地上面に接近させた状態で機体を前進させる。
前方の堆肥は、掬上板２４により掬上げられながら、横型ビータ４の掬取角αを有して相対向する二枚一組毎の羽根２６，２６によって上方に向け掻込まれ覆板２２との間の積込口２３から荷箱１のコンベア２上に放出され、コンベア２の回転により、荷箱１内へ取込まれる。なお、堆肥の山が低い場合には、横型ビータ４を反矢印イ方向へ回転させ、掬上板２４との間の積込口２５から強制的に掻込む如くすればよい。
この堆肥の積込時には、ビータ枠３の両側板６，６の開口７，７を散布案内板８，８によって閉鎖し、堆肥の積込案内作業を行う。
堆肥の散布時には、油圧シリンダー３８を作動させ、荷箱１を水平状態にするとともに、操作レバー３１を操作してビータ枠３両側の散布案内板８，８を外側方へ回動させ、両側板６，６の開口７，７を開放させる。
次に横型ビータ４を散布回転方向ロに、又、コンベア２を送出し方向に回転させると、コンベア２によって送出される堆肥は、各羽根２６，２６の中央の突起２７，２７によって切崩され、又、掬取角αを有して傾斜取着される羽根２６，２６の背面側で左右方向に分力を有して打叩くが如く作用させ、細かく砕きながら、均等に散布を行う。
又、各羽根２６，２６のうち、左右第１群と第２群の各組の側板６側に位置する羽根２６は、該回転方向ロの後方側に各突起２７，２７の先端を結ぶ円弧線に略連続して跳出翼２８を設け、更に、該跳出翼２８は外側方へ向け屈曲させ跳出面２９を形成してあり、上記のように羽根２６中央の突起２７により切崩された堆肥を該跳出面２９で受取り、その回転に伴って側板６側への分力を有して跳出を行う。
【００１１】
この跳出された堆肥は、側板６の開口７から散布案内板８に案内され前側方へ案内散布される為、横型ビータ４の幅約２〜３倍の広幅散布が行える。
又、側板６の開口７は、ビータ軸５の軸支部の上方でビータ枠３の略全長に亘って設けてあり、羽根２６の上昇回転中に跳出作用が行われる為、拡散効果が高い。
散布案内板８，８の上部に飛散規制板９，９を設けた場合には、開口７から上方へ跳出される堆肥を規制し、側方の散布案内板８側に案内する為、散布される堆肥の両側端を揃えることが出来、又、堆肥の塊り等がハウス側面まで跳飛されることもない。
又、中央の第３群の羽根２６，２６には跳出翼２８を設けず散布幅中央の散布量も確保して広幅で均一な散布を行なうことが出来る。
横型ビータ４の幅と同程度の狭幅散布を行なう場合には、散布案内板８，８を操作して側板６，６の開口７，７を閉鎖するとともに、横型ビータ４を反矢印ロ方向に回転させ、掬上板２４の下部散布口２５から繰出し散布を行う。
