Description

【発明の属する技術分野】
【０００１】
本発明は、コンバイン等の脱穀装置に関するものである。
【従来の技術】
【０００２】
例えば、実開平３−５６３３１号のマイクロフィルムには、移動側板に軸支された扱胴と脱穀済みの排藁を搬送する排藁搬送装置とを非作業位置へ移動できるように構成し、前記排藁搬送装置を支持する脱穀室の上部カバ−側に設けたフックと脱穀装置本体側に設けた係合部材とからロック装置を形成して該ロック装置を搬送穀稈の株元部の通過を妨げないように脱穀室後方に離間させてフィ−ドチェン側に配置し、該ロック装置を介して前記扱胴と排藁搬送装置とが作業位置に保持されるように構成し、前記ロック装置を係合離脱させるレバーの端部を穀稈搬送通路の上方に配置した構成の脱穀装置が記載されている。
【発明が解決しようとする課題】
【０００３】
上述の実開平３−５６３３１号のマイクロフィルムに記載された脱穀装置においては、扱胴と排藁搬送装置とを作業位置に保持するロック装置がフィ−ドチェン側に設けられるため、このフィ−ドチェン及びこれに続く排藁搬送装置によって搬送される穀稈の株元部がこのロック装置に干渉しないように、このロック装置を脱穀室後方に大きく離れた位置（斜設された排藁搬送装置によって排藁株元部が脱穀装置内部に引き込まれてしまう位置よりも更に後方の位置）に配置せざるをえない。このようにロック装置が扱胴から離れた位置に配置されると、該扱胴を適正な作業位置に保持する上で強度的に不利であり、例えば脱穀負荷によって扱胴が上動し、該扱胴と受網との間隔が広がって穀稈に適正な脱穀作用を与えられなくなり、脱穀作業を円滑に行うことができなくなる問題がある。また、ロック装置を係合離脱させるレバーの端部を穀稈搬送通路の上方に配置した構成なので、穀稈が多量に搬送されて来ると穀稈がレバーに当接してしまい、搬送の抵抗となり搬送乱れが発生するという問題がある。
【０００４】
また、このロック装置は、脱穀室の上部カバ−側に設けたフックと脱穀装置本体側に設けた係合部材とだけによって形成されるため、上述のように脱穀負荷によって扱胴を上下動させる力が作用した場合、この扱胴を軸支する移動側板およびこの移動側板と一体の上部カバ−が上下動してこの上部カバ−側のフックが動き、このフックと脱穀装置本体側の係合部材との相対位置が狂ってフックが係合部材から外れやすく、扱胴を適正な作業位置に保持することが困難となる欠点がある。
【課題を解決するための手段】
【０００５】
本発明は、上記課題を解決するために、つぎの技術的手段を講じた。
すなわち、移動側板２６に軸支された扱胴５と脱穀済みの排藁を搬送する排藁搬送装置６２とを非作業位置へ移動できるように構成し、前記移動側板２６と脱穀装置１本体側の固定側板２９との分割面付近に配置したロック装置３２を介して前記扱胴５と排藁搬送装置６２とを作業位置に保持できるように構成するに、前記移動側板２６の上部と下部とに上側のフック３３と下側のフック３３とを夫々軸着し、該上側のフック３３と下側のフック３３との上下中間位置に係合ピン３４を出入自在に設け、前記固定側板２９に前記上側のフック３３が係合する上側の係合部材４１と下側のフック３３が係合する下側の係合部材４１とを夫々設け、該上側の係合部材４１と下側の係合部材４１との上下中間位置には前記係合ピン３４の先端が嵌合する係合筒４２を固定し、移動側板２６側に軸着した操作レバ−３５の上方回動によって前記上側のフック３３と下側のフック３３とが前記上側の係合部材４１と下側の係合部材４１とに対して外開き回動して外れると共に前記係合ピン３４の先端が係合筒４２から抜けてロック装置３２のロックが解除されるように構成したことを特徴とする脱穀装置としたものである。
【０００６】
しかして、移動側板２６側に軸着した操作レバ−３５を上方回動させると、上側のフック３３と下側のフック３３とが上側の係合部材４１と下側の係合部材４１とに対して外開き回動して外れ、これと共に、係合ピン３４の先端が係合筒４２から抜ける。これによってロック装置３２のロックが解除され、移動側板２６に軸支された扱胴５も非作業位置へ移動できるようになる。
【０００７】
一方、前記ロック装置３２をロック状態とすると、扱胴５と排藁搬送装置６２とが作業位置に保持される。この際、ロック装置３２が前記移動側板２６と固定側板２９との分割面付近に配置されるため、該ロック装置３２は、搬送穀稈に干渉しにくい位置でありながら、より扱胴５に近い位置において該扱胴５を作業位置に保持することとなる。
【０００８】
さらに、多量の穀稈が搬送されてくると扱胴５と扱網との間隔が開こうとするが、移動側板２６の上部と下部とに軸着した上側のフック３３と下側のフック３３とが、固定側板２９に設けた上側の係合部材４１と下側の係合部材４１とに上側及び下側から夫々係合すると共に、移動側板２６側に設けた係合ピン３４の先端が固定側板２９側に設けた係合筒４２に嵌合するため、係合ピン３４と係合筒４２との嵌合によって移動側板２６と固定側板２９との相対位置が決まり、フック３３，３３と係合部材４１，４１との位置関係が狂いにくくなってロック装置３２のロック状態が適正に維持され、扱胴５と扱網との間隔が適正な作業間隔に保持される。
【発明の効果】
【０００９】
本発明によると、扱胴５と排藁搬送装置６２とを非作業位置に移動させて脱穀装置１のメンテナンスを容易に行うことができると共に、脱穀作業時においては、扱胴５と排藁搬送装置６２とを作業位置に保持するロック装置３２が、搬送穀稈に干渉しにくい位置でありながら、より扱胴５に近い位置において該扱胴５を作業位置に保持することとなるため、該扱胴５を適正な作業位置に保持する上で強度的に有利となり、このロック装置３２の合理的な配置によって扱胴５と排藁搬送装置６２とを適正な作業位置に保持して脱穀作業を円滑に行うことができる。
【００１０】
そして、多量の穀稈が搬送されてくると扱胴５と扱網との間隔が開こうとするが、移動側板２６の上部と下部とに軸着した上側のフック３３と下側のフック３３とが、固定側板２９に設けた上側の係合部材４１と下側の係合部材４１とに上側及び下側から夫々係合すると共に、移動側板２６側に設けた係合ピン３４の先端が固定側板２９側に設けた係合筒４２に嵌合するため、係合ピン３４と係合筒４２との嵌合によって移動側板２６と固定側板２９との相対位置が決まり、フック３３，３３と係合部材４１，４１との位置関係を狂いにくいものとしてロック装置３２のロック状態を適正に維持し、扱胴５と扱網との間隔を適正な作業間隔に保持して扱ぎ残しの発生を防止し、脱穀効率を向上させることができる。
【発明の実施の形態】
【００１１】
本発明の実施の形態を図により説明すると、１は、設置型またはコンバインあるいはハーベスター等に設けられる自走型の脱穀装置であり、一側を供給側２に他側を排出側３に形成し、前記供給側２の上方位置には脱穀室４を形成する。５は前記脱穀室４内に軸装した扱胴、６は該扱胴５の主として下方側に設けた扱網、７は前記脱穀室４の穀稈供給口、８は前記脱穀室４の穀稈排出口、９は前記扱網６の下方に設けた移送装置、１１は前記移送装置９の外周面に移送螺旋１０を有する移送ロール、１２は該移送ロール１１の下方に設けた底板、１３は前記脱穀室４の排塵口、１４は前記排塵口１３の下方から排出側３側に形成した風選室、１５は該風選室１４内に設けた揺動選別枠体、１６は一番コンベア、１７は二番コンベア、１８は前記二番コンベア１７の終端部に基部を接続した二番物戻し装置、１９は送風唐箕２０を軸装した送風室、２１は前記移送装置９の底板１２の下面と前記送風室１９の上面との間に形成した補助送風路であり、前記送風室１９の非作用域に送風して扱網６より落下する脱穀物を拡散させる。２２は補助送風唐箕である。
【００１２】
前記扱胴５は、扱胴軸２４により前記脱穀室４の供給側移動側板２５と排出側移動側板（移動側板）２６の間に軸装し、供給側２を中心に外開き回動自在に構成する。即ち、前記供給側移動側板２５は、その後側端縁を供給側固定側板２７に軸着金具２８により回動自在に取付け、前記排出側移動側板２６は脱穀装置１の排出側固定側板（固定側板）２９に対して着脱自在に構成し、供給側移動側板２５と排出側移動側板２６に支持された扱胴５は外開き回動する。
【００１３】
軸着金具２８の軸心方向は、前側を低く、後側に至るに従い高くなるように傾斜させ、前記扱胴５を回動させると、扱胴５の回動端は外側に回動させるほど高くなるように構成している。３０は前記供給側移動側板２５と前記排出側移動側板２６との間には複数設けた補強横杆であり、補強横杆３０のうち下方に位置する補強横杆３０は前記扱網６を上方から押える位置に配設して扱胴５を格納したとき、扱網６を上方から押さえて扱胴５の回転と共回りするのを防止し、補強横杆３０のうち前記扱胴５の回転上昇側にある補強横杆３０には切歯３１を設ける。切歯３１は扱胴５に巻き付いた藁屑等を切断し、前記排塵口１３より落下する落下物が細かくなるようにしている。
【００１４】
前記排出側移動側板２６と排出側固定側板２９との間にロック装置３２を設ける。ロック装置３２は、排出側移動側板２６の後側端縁の上部と下部にフック３３、３３の中間部を軸着し、フック３３とフック３３の上下中間位置に出入自在の係合ピン３４を設け、前記排出側移動側板２６には操作レバー３５の基部を軸筒３６に固定し、軸筒３６は前記排出側移動側板２６に固定の軸３７に嵌合させ、前記軸筒３６にはアーム３８の基部を固定し、アーム３８の中間部と前記フック３３とをロッド３９により連結し、ロッド３９の先端に前記係合ピン３４の前端部を軸着し、前記操作レバー３５の基部側と前記フック３３とをロッド４０により連結する。他方、前記排出側固定側板２９には前記フック３３、３３が係合する係合突起（係合部材）４１、４１を設け、係合突起４１と係合突起４１の間には前記係合ピン３４の先端が嵌合する係合筒４２を固定する。
【００１５】
しかして、前記脱穀室４の前側には、前記穀稈供給口７から前記穀稈排出口８に至る穀稈供給搬送通路４３を形成する。該穀稈供給搬送通路４３は、前記脱穀装置１の前板４４の上縁と、前記脱穀室４の上方を覆う上部カバー４５との間に形成され、該穀稈供給搬送通路４３の前側には脱穀室４に穀稈を供給する穀稈供給装置４６を設ける。該穀稈供給装置４６は、供給搬送チエン４７と該供給搬送チエン４７に弾力的に当接する挾扼杆４８とにより構成され、前記挾扼杆４８は前記上部カバー４５の前側内面に取付けられ、上部カバー４５の前側を上動させると、一体的に上動するように構成している。４９は前記供給搬送チエン４７のチエン案内レールであり、枠体５０に取付けられる。枠体５０は、その供給側２の縦杆をステー５１の先端縁に固定し、ステー５１の基部側を軸筒５２に固定し、該軸筒５２を機体側に支持されている縦軸５３に軸着し、チエン案内レール４９は縦軸５３を中心に外開き回動自在に構成している。５４は前記穀稈供給装置４６の駆動歯車であり、チエン案内レール４９とともに回動可能に伝動軸５５側に接続する。５６は前記チエン案内レール４９の終端部に設けた受動歯車であり、受動歯車５６には伝動軸５７の一端を着脱自在に取付け、伝動軸５７の他端にはプーリ５８を固定する。前記伝動軸５７の近傍には該伝動軸５７と平行な伝動軸５９を設け、該伝動軸５９の一端にプーリ６０を固定し、プーリ６０と前記プーリ５８との間にベルト６１を掛け回す。前記伝動軸５９の他端は前記穀稈供給装置４６の終端部に始端部を臨ませた排藁搬送装置６２の搬送チエン６３の駆動歯車６４を設けたギヤボックス６５に接続する。したがって、前記穀稈供給装置４６と排藁搬送装置６２との一方または両方が穀稈が詰まって停止しても、ベルト６１が空回りして各部の損傷を防止している。
【００１６】
しかして、前記排藁搬送装置６２は、前記脱穀室４の排出側３に設けた排藁搬送室９６内に設けられ、前記搬送チエン６３と該搬送チエン６３に対応する挾扼杆６６とにより構成される。前記挾扼杆６６は前記排藁搬送室９６内の機体側に取付けるが、搬送チエン６３は前記上部カバー４５と一体的に上下動する。前記上部カバー４５の中間板６７には、搬送チエン６３を取付けるコ型形状の取付フレーム６８の前後杆６９、７０の供給側２端部を固定する。取付フレーム６８は、前後杆６９、７０の排出側３を連結杆７１により連結し、前記取付フレーム６８の排出側３側を機体側に支持させる。前記排藁搬送チエン６３は前記ギヤボックス６５および搬送チエン６３の受動歯車７２を前記取付フレーム６８に取付け、上部カバー４５と一体的に上下させる。
【００１７】
しかして、前記上部カバー４５は、前記搬送チエン６３とともに上下するが、上部カバー４５と機体側との間には複数のロック部７３、７４、７５を有するロック装置７６を設け、該ロック装置７６は操作レバー７７により一度にロック解除しうるように構成する。前記供給側ロック部７３は供給側２に設けられ、前記脱穀装置１の供給側移動側板２５の前側部分に係合軸７８を設け、該係合軸７８に係合する係合フック７９の中間部を前記上部カバー４５に軸着して構成する。係合フック７９の前端には操作レバー７７の供給側２端部を固定し、操作レバー７７は前記脱穀室４の前板４４と平行に位置させ、操作レバー７７の排出側３は前記中間板６７の位置にて後側に屈曲させ、その端部には係合フック８０の前端部を固定する。係合フック８０は前記中間板６７に軸着し、前記排出側移動側板２６には係合フック８０が係合する係合軸８１を設け、前記係合フック８０および係合軸８１により前記中間ロック部７４を構成する。
【００１８】
前記取付フレーム６８の前杆６９には、支持板８２を複数設け、該支持板８２には前杆６９と平行の回転軸８３を軸着し、回転軸８３の排出側３側に係合フック８４の基部を固定し、係合フック８４は、排藁処理部８５のフレーム８６に設けた係合軸８７に係合させ、前記係合フック８４と係合軸８７により排出側ロック部７５を構成する。前記回転軸８３の供給側２にはアーム８８の基部を固定し、アーム８８の先端と前記係合フック８０に設けたアーム８９の先端との間をロッド９０により連結する。
【００１９】
図中、９１は処理胴、９２は排塵胴、９３は横断流吸引ファン、９４はカッタ、９５は拡散装置である。
上記の構成であるから、穀稈は穀稈供給装置４６により穀稈供給口７より脱穀室４内に供給され、穀稈排出口８より排出されるまでの間に回転する扱胴５により脱穀され、脱穀物は扱網６より漏れ移送装置９上に落下し、移送装置９により排出側３に向けて移送されて風選室１４内に入り、また、脱穀室４内の脱穀物は排塵口１３より風選室１４内に入り、送風室１９の送風唐箕２０により送風される選別風および揺動選別枠体１５の揺動により選別され、一番物は一番コンベア１６に入って機外に取出され、二番物は二番コンベア１７に入る。二番コンベア１７に入った二番物は二番物戻し装置１８により移送装置９の始端部側に戻され、回転する移送装置９の移送ロール１１の移送螺旋１０により移送される間に処理されて、風選室１４に戻され風選される。
【００２０】
しかして、穀稈供給装置４６により搬送された穀稈は、排藁搬送装置６２に引継がれ、脱穀室４の排出側３に設けた排藁搬送室９６内を搬送されて排藁処理部８５に至り、カッタ９４で切断される（結束装置により結束することもある）。
【００２１】
しかして、前記上部カバー４５は、その後側を脱穀室４の後板側に軸着し、その前側が上下するように構成されており、前記穀稈供給装置４６の挾扼杆４８および前記排藁搬送装置６２の搬送チエン６３を取付けた取付フレーム６８は前記上部カバー４５に取付けられているから、上部カバー４５を上動させると、穀稈供給装置４６の挾扼杆４８および排藁搬送装置６２の搬送チエン６３が上動し、搬送チエン４７と挾扼杆４８との間および搬送チエン６３と挾扼杆６６との間に空間が形成されるので、藁詰まりの除去等のメンテナンスが行なえる。また、上部カバー４５を上動させると、脱穀室４の上方が開放されるので、脱穀室４内のメンテナンスを行なえる。
【００２２】
この場合、上部カバー４５の供給側２に供給側ロック部７３の係合フック７９を軸着し、供給側２と排出側３との中間位置に中間ロック部７４の係合フック８０を設け、係合フック７９と係合フック８０とは操作レバー７７により連結しているので、操作レバー７７を上方に持ち上げると、係合フック７９および係合フック８０は回動して係合軸７８および係合軸８１から離脱する。そして、前記係合フック８０が回動すると、係合フック８０と一体的にアーム８９が回動し、アーム８９はロッド９０を牽引し、ロッド９０はアーム８９を回動させて回転軸８３を回転させ、回転軸８３は排出側ロック部７５の係合フック８４を係合軸８７により離脱させる。したがって、ロック装置７６の供給側ロック部７３と中間ロック部７４と排出側ロック部７５の各フックを前記操作レバー７７の一操作により回動させてロックを解除するので、上部カバー４５を簡単に上動させてメンテナンスができる。
【００２３】
しかして、扱胴５の上方を覆う上部カバー４５を上動させ、穀稈供給装置４６のチエン案内レール４９の終端部を外側回動させ、次に、操作レバー３５を上方回動させてロッド４０によりフック３３の基部を牽引し、アーム３８により係合ピン３４を前側に移動させ、また、アーム３８の回動によりロッド３９を牽引してフック３３の基部を牽引すると、フック３３、３３は同時に係合突起４１、４１に対して外開き回動して外れ、係合ピン３４は係合筒４２から抜け、排出側移動側板２６と排出側固定側板２９との間のロック装置３２のロックが外れるので、この状態で、排出側移動側板２６側を外側回動させると、扱胴５は外開き回動し、前記メンテナンスが行なえる。
【００２４】
また、上部カバー４５は、供給側ロック部７３と、中間ロック部７４と、排出側ロック部７５の３箇所で固定されるので、穀稈供給装置４６の終端部と排藁搬送装置６２の始端部との上下間隔が一定となり、藁詰まりを防止する。
【００２５】
また、排藁搬送装置６２を取付けた取付フレーム６８は、図示は省略するが、取付フレーム６８の前杆６９と連結杆７１とを搬送チエン６３の案内レールで連結されているから、脱穀室４および上部カバー４５の強度を確保する。
【００２６】
また、前記排藁搬送装置６２の挾扼杆６６の終端部は、前記上部カバー４５の回動中心より前側に位置させているから、挾扼杆６６と搬送チエン６３との間の間隔を広く開けることができ、詰まり藁の除去を容易にする。
【００２７】
以上のように、上部カバー４５を複数箇所で閉鎖位置に固定するロック手段７６を手動解除手段７７の一操作で解除するので、上部カバー４５の開閉を容易にし、メンテナンスを容易にできる。

６２排藁搬送装置BACKGROUND OF THE INVENTION
[0001]
The present invention relates to a threshing apparatus such as a combine.
[Prior art]
[0002]
For example, the microfilm of Japanese Utility Model Laid-Open No. 3-56331 is configured so that the handling cylinder pivotally supported on the moving side plate and the waste conveying device for conveying the threshed waste can be moved to the non-working position, A lock device is formed from a hook provided on the upper cover side of the threshing chamber for supporting the scouring and conveying device and an engaging member provided on the threshing device main body, and the lock device is passed through the stock base of the conveying cereal. So as not to interfere with the threshing chamber and disposed on the feed chain side, and the handling cylinder and the waste transporting device are held in a working position via the locking device, and the locking device A threshing device having a configuration in which an end portion of a lever that engages and disengages is disposed above a cereal conveying path is described.
[Problems to be solved by the invention]
[0003]
In the threshing device described in the above-mentioned microfilm of Japanese Utility Model Publication No. 3-56331, a lock device for holding the handling cylinder and the waste transporting device in the working position is provided on the feed chain side. In addition, the locking device is moved to a position far behind the threshing chamber so that the stock base portion of the cereals conveyed by the subsequent discharging and conveying device does not interfere with the locking device (by the inclined conveying device arranged obliquely). It must be arranged at a position further rearward than the position where the slaughter root is drawn into the threshing apparatus. When the locking device is arranged at a position away from the handling cylinder in this way, it is disadvantageous in strength to hold the handling cylinder in an appropriate working position.For example, the handling cylinder is moved up by a threshing load, and the There is a problem that an interval between the handling cylinder and the receiving net is widened so that an appropriate threshing action cannot be given to the cereal and the threshing operation cannot be performed smoothly. In addition, since the end of the lever that engages and disengages the locking device is arranged above the cereal conveyance path, if a large amount of cereal is conveyed, the cereal will abut against the lever, resulting in conveyance resistance. There is a problem that conveyance disturbance occurs.
[0004]
Moreover, since this locking device is formed only by the hook provided on the upper cover side of the threshing chamber and the engaging member provided on the threshing device main body side, the handling cylinder is moved up and down by the threshing load as described above. When a force is applied, the moving side plate pivotally supporting the handling cylinder and the upper cover integrated with the moving side plate move up and down to move the hook on the upper cover side, and the hook is engaged with the threshing device main body side. There is a drawback that the relative position with respect to the member is out of order and the hook is easily detached from the engaging member, making it difficult to hold the handling cylinder in an appropriate working position.
[Means for Solving the Problems]
[0005]
In order to solve the above problems, the present invention has taken the following technical means.
That is, configured to the straw discharge conveying device 62 for conveying the threshing already straw discharge the threshing drum 5 is supported by a moving plate 26 can be moved to the non-working position, the movable side plate 26 and the threshing apparatus 1 main body An upper portion and a lower portion of the moving side plate 26 are configured so that the handling cylinder 5 and the waste transporting device 62 can be held at a working position via a lock device 32 disposed in the vicinity of a split surface with the fixed side plate 29 on the side. An upper hook 33 and a lower hook 33 are respectively pivotally attached to each other, and an engaging pin 34 is provided in a vertically intermediate position between the upper hook 33 and the lower hook 33 so as to be freely inserted and removed. Are provided with an upper engaging member 41 with which the upper hook 33 engages and a lower engaging member 41 with which the lower hook 33 engages, respectively. The front end of the engaging pin 34 is fitted in the upper and lower intermediate position with the joint member 41. The upper hook 33 and the lower hook 33 are connected to the upper engagement member 41 and the lower hook 33 by the upward rotation of the operation lever 35 which is fixed to the engagement cylinder 42 and pivotally attached to the moving side plate 26 side. The threshing is characterized in that it is configured such that the engagement pin 41 is pivoted outwardly and disengaged, and the tip of the engagement pin 34 is detached from the engagement tube 42 and the lock device 32 is unlocked. It is a device.
[0006]
Accordingly, when the operation lever 35 pivotally attached to the moving side plate 26 is rotated upward, the upper hook 33 and the lower hook 33 are turned into the upper engaging member 41 and the lower engaging member 41. On the other hand, it pivots outward and disengages, and at the same time, the tip of the engagement pin 34 comes out of the engagement cylinder 42. As a result, the lock of the lock device 32 is released, and the handling cylinder 5 pivotally supported by the moving side plate 26 can also move to the non-working position.
[0007]
On the other hand, when the locking device 32 is in the locked state, the handling cylinder 5 and the waste transporting device 62 are held at the work position. At this time, since the locking device 32 is disposed in the vicinity of the dividing surface of the moving side plate 26 and the fixed side plate 29, the locking device 32 is closer to the handling cylinder 5 while being in a position where it is difficult to interfere with the transporting culm. The handling cylinder 5 is held at the working position at the position.
[0008]
Further, when a large amount of cereal is conveyed, the space between the handling cylinder 5 and the handling net tends to be increased, but the upper hook 33 and the lower hook 33 that are pivotally attached to the upper and lower portions of the moving side plate 26. Are engaged with the upper engaging member 41 and the lower engaging member 41 provided on the fixed side plate 29 from the upper side and the lower side, respectively, and the tips of the engaging pins 34 provided on the moving side plate 26 side are In order to fit into the engagement cylinder 42 provided on the fixed side plate 29 side, the relative position between the moving side plate 26 and the fixed side plate 29 is determined by the engagement of the engagement pin 34 and the engagement cylinder 42. The positional relationship between the engagement members 41 and 41 is less likely to be distorted, and the lock state of the lock device 32 is properly maintained, and the interval between the handling cylinder 5 and the handling net is maintained at an appropriate work interval.
【The invention's effect】
[0009]
