Description

【0001】
【産業上の利用分野】
本発明は、甘藷などの地下茎作物の茎葉部だけを引き抜いて収集処理する茎葉処理機に関するものである。
【0002】
【従来の技術】
馬鈴薯や甘藷等の地下茎作物の収穫に当たっては、地上部分(茎葉)だけを先に引き抜いて除去する前処理作業を行い、その後に、地下部分(いも)を掘り上げて収集する手法がとられるが、人手による前処理作業は、中腰姿勢での重労働になるので、その前処理作業を省労力に行う茎葉処理機が開発されている(例えば、実公平6−8660号公報参照)。
【0003】
そして、従来の茎葉処理機は、馬鈴薯などの茎葉部を後方に掻き込む掻込装置と、掻込装置によって掻き込まれた茎葉部を前方の始端部で挾持して後上方に移送しつつ引き抜いて後上方に移送する挾持移送装置と、挾持移送装置からの移送物を受け継いで更に後上方に揚上移送する上部移送装置と、上部移送装置の移送終端部から送出される移送物を収集して所定量収集するごとに放出する収集放出装置等からなる処理作業部を、自走車の前部に装備して構成されていた。
【0004】
【発明が解決しようとする課題】
上述の茎葉処理機によれば、自走車の進行に連れて圃場に植立している地下茎作物の茎葉部が掻込装置により掻き込まれて挾持移送装置に受け渡されるのであるが、茎葉部が地を這うように繁茂する蔓状のものであったり、地面に沿って倒伏したものであって、隣接する条列の茎葉部が互いに絡まり合った状態になっていると、従来の茎葉処理機では、隣接する条列の茎葉部が完全に分け捌かれることなく互いに絡まり合った儘で掻込装置から挾持移送装置に受け渡されて搬送されるため、大きな移送抵抗が掛って茎葉部だけの抜き上げ処理が良好に行われ難く、挾持移送装置の移送圏内の地下部(イモ)や、更には、隣接する条列の茎葉部や地下部分までを不測に抜き上げることになりかねないという問題があった。
【0005】
【課題を解決するための手段】
そこで、本発明は、蔓状の茎葉部や地面に沿って倒伏した茎葉部であってもその抜き上げ処理を良好に行うことができるようにした茎葉処理機を合理的な伝動構成にして提供することを目的として実施したものであり、この目的を達成するため、本発明における茎葉処理機は、左右一対の横廻し搬送ベルトによって挾持移送経路を形成する挾持移送装置(12)を前低後高に傾斜設置し、挾持移送経路(12)の始端側に左右一対の横廻し掻込ベルトからなる掻込装置(13)を連設した茎葉処理機において、前記挾持移送装置(12)の外側部に、ケ−シング(29)内に掛回する縦廻しチエン(28)に切断刃(30)を具備して構成した引起し切断装置(27)を設け、その引起し切断装置(27)のチエン(28)を、挾持移送装置(12)の横廻し搬送ベルトを回転駆動する駆動軸(21)からの伝達動力で共通に駆動するようにしている。
そして、挾持移送装置(12)の横廻し搬送ベルトと、引起し切断装置(27)のチエン(28)とを相対的に異なる移行速度で回転させるように構成するのが好ましい。
【0006】
【発明の作用及び効果】
本発明の茎葉処理機によれば、茎葉部が蔓状であったり、地面に沿って倒伏して地を這うような状態に絡まり合っていても、その状態の茎葉部を、挾持移送装置(12)の外側部に配設されている引起し切断装置(27)が引起し整姿しながらそれに付設された切断刃(30)で切り捌いて、移送圏内の地下部に近い茎葉部のみを挾持移送装置(12)が抜き揚げ搬送するので、移送圏内の地下部や、隣接する条列の茎葉部、地下部などを連れ抜きすることがなくなって良好な茎葉処理が軽快に行われるのであり、引起し切断装置(27)を備えながらも、該装置(27)が挾持移送装置(12)の横廻し搬送ベルトを回転駆動する駆動軸(21)からの伝達動力で共通に駆動されるようにしてあるので、伝動構成の簡潔コンパクトに纏まって挾持移送装置(12)による茎葉部の移送に不具合を生じさせるようなことがない。
そして、挾持移送装置(12)の搬送移行速度と引起し切断装置(27)の回転移行速度とを相対的に異ならせるようにした場合には、その相対的速度差でもって切断刃(30)の切断作用が助勢されることになって、切断刃(30)による茎葉部の切り捌きがより良好に行われる。
【0007】
【実施例】
つぎに、本発明の実施例について図面を参照して説明するが、図1は本発明に係る茎葉処理機を右斜め前方から見た全体斜視図、図2は本発明に係る茎葉処理機の左側面図、図3は引起し切断装置を駆動する伝動構成示した要部の断面図である。
【0008】
図1および図2において、茎葉処理機は、自走車(1)とその車体の前部に装備される処理作業部(2)とで構成されている。
自走車(1)は、エンジン(3)と、エンジンの出力部に連動する伝動機構を収蔵したミッションケ−ス(4)と、ミッションケ−スから前延される左右一対の車軸ケ−ス(5)と、各車軸ケ−スに軸支される駆動車輪(6)と、ミッションケ−ス及び車軸ケ−スに取付支持された作業部支持フレ−ム(7)と、ミッションケ−ス内の伝動機構に連動する作業機駆動機構を収容した作業機駆動ケ−ス(8)と、作業部支持フレ−ムの前後中程部からエンジンの上方を経て後方に延設される歩行操縦ハンドル(9)などによって構成されている。
【0009】
処理作業部(2)は、前記作業部支持フレ−ム(7)から前方斜め下方に延出される左右一対の作業機フレ−ム(10)と、左右の作業機フレ−ムの前端部にそれぞれ取付けられる固定分草板(11)と、前記作業機駆動ケ−ス(8)の上方に前低後高に傾斜設置される挾持移送装置(12)と、挾持移送装置の挾持移送経路の始端側に連設される掻込装置(13)と、挾持移送装置の後方両側に配設される左右一対の収集放出装置(14)と、挾持移送装置の下側に配設される左右一対の転圧支持輪(15)及びイモ落しガイドなどを備えて構成されている。
【0010】
掻込装置(13)は、左右の固定分草板(11)(11)によって分草されて作業機フレ−ム(10)(10)間に導入される茎葉部を掻き込んで挾持移送装置(12)に受け継ぎさせるものであり、縦軸中心で横廻りするように掛回した左右一対の掻込突起付ベルトを前方拡がりのハ字状に配設して、後方狭まり部が挾持移送装置(12)の挾持移送経路始端部に連絡するように設けられ、挾持移送装置(12)を経て伝達される動力で共通に回転駆動されるようになっている。
【0011】
また、挾持移送装置(12)は、縦軸中心で横廻りするように掛回する左右一対の軟弾性無端搬送ベルトを備え、両無端搬送ベルトの対向面間に挾持移送経路を形成するものであり、各々の無端搬送ベルトは、左右の作業機フレ−ム(10)に各々取付けられる搬送ケ−ス(17)(17)に縦軸で支承した輪体群(18)(19)(20)にそれぞれ掛回されている。
【0012】
そして、各々の搬送ケ−ス(17)に設けられる輪体群(18)(19)(20)うち前後方向の中程部に位置する輪体(19)が駆動輪体とされて、該駆動輪体(19)が前記作業機駆動ケ−ス(8)から上向きに突設される駆動軸(21)に取付けられて駆動軸(21)から駆動輪(19)に伝達される動力でもって各々の無端搬送ベルトを所定の方向に回転させるように構成されている。
【0013】
また、各々の搬送ケ−ス(17)は、前記駆動軸(21)の軸芯を中心にしてケ−ス後半部が、ケ−ス前半部に対して左右に屈折回動できるようになっており、操作把手(22)による切り替え操作でもってケ−ス後半部を左又は右に屈折させることにより、両無端搬送ベルト間の挾持移送経路の終端部を、左又は右側の収集放出装置(14)に選択的に対応位置させることができるようになっている。
そして、図3に示すように、駆動軸(21)は、搬送ケ−ス(17)の上面側に延設されて、後述する引起し切断装置(27)を駆動する引起し切断具駆動部(A)に入力するようになっている。
【0014】
引起し切断具駆動部(A)は、搬送ケ−ス(17)の上面に配設するベベルギア箱(23)内に前記駆動軸(21)を突入させてベベルギア(24)を嵌着し、そのベベルギア(24)を、ベベルギア箱(23)に支承した横向きの被動軸(26)に嵌着するベベルギア(25)に常時咬合させて、被動軸(26)から引起し切断装置(27)に動力伝達して同装置(27)を回転駆動するように構成されている。なお、引起し切断具駆動部(A)は、前記挾持移送装置(12)の移送速度に対して相対的に異なる速度で引起し切断装置(27)を作動させるように速度設定してある。
【0015】
図示された引起し切断装置(27)は、挾持移送装置(12)の左右の搬送ケ−ス(17)(17)の上面側において、各々の搬送ケ−ス(17)の外側寄り部位にケ−シング(29)(29)をそれぞれ配設し、各々のケ−シング(29)内に横軸中心で縦廻りするように縦廻しチエン(28)を掛回して、その縦廻しチエン(28)に適宜のピッチで切断刃(30)・・を装備し、それらの切断刃(30)が所定の部位においてケ−シング(29)から上方に突出して挾持移送装置(12)の傾斜に略沿って前下方から後上方に移行するように構成されている。
【0016】
更に詳述すると、引起し切断具駆動部(A)の被動軸(26)のケ−シング(29)内突入部に嵌着する駆動スプロケット(31)と、ケ−シング(29)の他部位に横軸支承した従動スプロケット(32)(33)とにチエン(28)を三角状状に掛回して、そのチエン(28)に適宜数の切断刃(30)・・を起立回倒可能に取付け、これらの切断刃(30)が、ケ−シング(29)の上面側においてケ−シング(29)から上向きに起立突出して前記挾持移送装置(12)の傾斜に略沿って後上方に移行し、それ以外の部位においてはケ−シング内に回倒収納されて移行するように構成されている。
【0017】
なお、切断刃(30)がケ−シング(29)の外方に突出開始する位置、およびケ−シング(29)内に退入する位置は、掻込装置(13)や挾持移送装置(12)との関連において適宜に設定すればよい。また、チエン(28)への切断刃(30)の装着は、起立回倒構造に限られるものではなく、要は、切断刃(30)が所要の部位においてはケ−シング(29)から突出して移行し、それ以外の部位においてはケ−シング(29)内に収納されて移行されるものであれば、チエン(28)に対して固定的に取り付けられるものであってもよい。
【0018】
また、前記引起し切断具駆動部(A)にクラッチを備えさせて、左右の縦廻しチエン(28)(28)を共に停止させたり、左右のいずれか一方のみを停止させておけるようにすると便利であり、さらに、引起し切断装置(27)は、挾持移送装置(12)の左右いずれか片側のみにケ−シング(29)および縦廻しチエン(28)を備えるものにすることもできる。
【0019】
また、チエン(28)には切断刃(30)・・のみを設けてもよいが、場合によっては、切断刃(30)と引起し突起(34)とを併設して、引起し突起(34)による茎葉部の係引搬送整姿作用と、切断刃(30)による切り捌き作用とをほど好く行わせるように構成することもでき、その場合の切断刃(30)と引起し突起(34)の個数や配列など、例えば、両者を一個ごと交互に設けるなど必要に応じて適宜に設定装設すればよい。
さらに、図示の実施例では、切断刃(30)がケ−シング(29)の上面側においてケ−シング(29)から上向きに突出して挾持移送装置(12)の傾斜に略沿って後上方に移行するようにしているが、切断刃(30)が、挾持移送装置(12)の搬送ケ−ス(17)上面に対面する側、つまり、ケ−シング(29)の下面側においてケ−シング(29)から下向きに突出して、挾持移送装置(12)の傾斜に略沿って移行するように構成することもでき、そのようにした場合には、切断刃(30)に引っ掛って移行する茎葉部が搬送ケ−ス(17)上面との間で摺接抵抗を受けるので切断性がより向上され、突出移行する切断刃(30)の上方がケ−シング(29)で被蓋されるので安全でもある。
【0020】
以上のように構成される本発明の茎葉処理機においては、エンジン(3)からミッションケ−ス(4)、車軸ケ−ス(5)を経て伝達される動力で駆動車輪(6)を回転して自走車が走行されるとともに、ミッションケ−ス(4)から作業機駆動ケ−ス(8)を経て伝達される動力で掻込装置(13)、挾持移送装置(12)および引起し切断装置(27)が回転駆動される。
【0021】
上述のように稼働する茎葉処理機を、対象作物が植立している圃場において進行させると、植立している対象作物の茎葉部を掻込装置(13)が掻き込み、その茎葉の基部両側を転圧支持輪(15)(15)でもって抑えた状態において挾持移送装置(12)に引き継がせて後上方に揚上搬送することによって地中部を土中に残しながら茎葉部のみを抜き上げ、挾持移送装置(12)の終端部で待ち受ける左右の収集放出装置(14)(14)のいずれかに収集するのであるが、このような一連の茎葉処理作業が行われる場合に、茎葉部が蔓状のものであったり倒伏したりしていて絡まり合った状態にあっても、その絡まり合った茎葉部を、挾持移送装置(12)の横外脇部位に配設された引起し切断装置(27)の切断刃(30)・・がケ−シング(29)から突出して挾持移送装置の傾斜に略沿って移行する間に切断して分け捌き、移送圏内の地下部に近い茎葉部のみを抜き揚げ搬送するので、移送圏内の地下部や、隣接する条列の茎葉部、地下部などを連れ抜きすることがなくなって良好な茎葉処理が軽快に行われる。

The cutting blade (30) is moved on the side facing the upper surface of the transport case (17) of the clamping and transferring device (12), that is, on the lower surface side of the case (29). It can also be configured to project downward from (29) and move substantially along the inclination of the holding and transferring device (12). In such a case, it moves by hooking on the cutting blade (30). Since the foliage receives the sliding contact resistance with the upper surface of the transport case (17), the cutting property is further improved, and the upper part of the cutting blade (30) which projects and moves is covered with the casing (29). So it is also safe.

In the foliage processing machine of the present invention configured as described above, the drive wheels (6) are rotated by the power transmitted from the engine (3) via the transmission case (4) and the axle case (5). The self-propelled vehicle travels, and the power transmitted from the transmission case (4) through the work implement drive case (8) drives the scraping device (13), the clamping and transferring device (12) and the raising device. The cutting device (27) is rotationally driven.
[0021]
When the foliage processing machine that operates as described above is advanced in the field where the target crop is planted, the scraping device (13) scrapes the foliage of the planted target crop, and the base of the foliage. With both sides held down by the rolling support wheels (15) and (15), they are taken over by the holding and transporting device (12), and then lifted and conveyed upward to remove only the foliage while leaving the underground portion in the soil. It is collected by one of the left and right collecting and discharging devices (14) and (14) waiting at the end of the lifting and holding and transferring device (12). When such a series of foliage processing operations is performed, the foliage is collected. Even if the vines are vine-shaped or laid down and are intertwined, the entangled foliage is raised and cut at the lateral outer side of the clamping and transferring device (12). The cutting blade (30) of the device (27) Since it protrudes from the shing (29) and cuts and separates while moving substantially along the slope of the clamping transfer device, only the foliage near the underground portion in the transfer area is extracted and transported. Good foliage treatment can be performed lightly without removing the foliage, underground, etc. of adjacent rows.
