Description

【0001】
【産業上の利用分野】
本発明は、コンバイン、ハーベスタ等のグレンタンクといわれる穀粒貯留装置に係るものである。
【0002】
【従来技術】
従来、脱穀装置の近傍に設けたグレンタンクを上部タンクと下部タンクとに分割形成し、前記上部タンクは下部タンクに対して上下する構成は、公知である。また、従来、グレンタンクを任意位置中心に外側に回動自在にした構成は、公知である。
【0003】
【発明が解決しようとする課題】
前記公知例のうち、上部タンクを上下させる構成が、タンク外側に露出させているので、オープンすることができずメンテナンスが面倒であるという課題がある。
また、前記公知例のうち、グレンタンクを回動させるものは、上部タンクを上下させることはできないという課題がある。また、上下機構を有するグレンタンクの取付構造は複雑なため、これを回動するようにすると、更に構造が複雑になり、コストが高く、また、重量も嵩むということになる。
本発明は、グレンタンクの容積を変更可能にして作業性を向上させつつ、グレンタンクのオープンを可能にしてメンテナンスを容易にしたものである。
【0004】
【発明の目的】
グレンタンクの容積変更可能化、グレンタンクのオープンを可能化、グレンタンクの軽量化、メンテナンス作業の容易化、全体の作業容易化。
【0005】
【課題を解決するための手段】
本発明は、脱穀装置2の近傍に設けたグレンタンク5を上部タンク11と下部タンク12とに分割形成し、前記上部タンク11は該上部タンク11と前記下部タンク12の間の内部に設けた上下機構13により上下するように構成し、前記グレンタンク5は後側の任意位置中心に外側に回動自在にし、前記脱穀装置2からの穀粒をグレンタンク5に供給する供給揚穀筒28は、下部筒33と上部筒34とに上下に分割形成し、前記上部筒34の上部の排出口を有する上部接続部29をグレンタンク5に接続離脱自在に取付け、前記上部筒34は、上部接続部29を上部タンク11に接続した状態において上下機構13により上部タンク11を上動させると、該上部タンク11によって牽引されて上部筒34が上動するように構成し、前記上部筒34の下部にはブレーキ体50を取付け、該ブレーキ体50は上部接続部29を前記上部タンク11から外してグレンタンク5を外側へ回動させた場合に前記上部筒34の下降を停止させることができるように構成した穀粒貯留装置としたものである。
本発明は、前記グレンタンク5の前方にキャビン56を設け、前記上部タンク11は最大に上昇させてもキャビン56の上面より下方に位置するように構成した穀粒貯留装置としたものである。
本発明は、前記下部タンク12の上部には穀粒センサ57を設け、少なくとも、穀粒センサ57が穀粒を検出しなくなると、上部タンク11を自動収納するように構成した穀粒貯留装置としたものである。
本発明は、前記上部タンク11の上部には穀粒センサ57を設け、該穀粒センサ57の穀粒検出または不検出により上部タンク11を自動的に上動または下動するようにした穀粒貯留装置としたものである。
本発明は、前記グレンタンク5は、下部タンク12を固定部に上下に所定間隔おいて同一軸心に位置するように設けた下部軸21と上部軸25を中心に外側に回動自在にした穀粒貯留装置としたものである。
本発明は、前記下部軸21は、前記グレンタンク5の排出装置6の排出筒7と、穀物排出用の揚穀排出装置8の下部に設けた下部メタル9との軸着部に設け、前記上部軸25は前記揚穀排出装置8側の上部に設けた上側回動支持部材23と下部タンク12との軸着部に設けた穀粒貯留装置としたものである。
【0006】
【実施例】
本発明の実施例をコンバインの例にて図面により説明すると、1は機体フレ−ム、2は機体フレ−ム1の上方位置に設けた脱穀装置、3は機体フレ−ム1の下方位置に設けた走行装置、4は機体フレ−ム1の前方に設けた刈取部である。
前記脱穀装置2の側部には、該脱穀装置2より取出された穀物を一時貯留するグレンタンク5を設ける。グレンタンク5内には該タンク5内の穀物を排出する排出装置6を設け、排出装置6の排出筒7には該グレンタンク5内の穀物を揚穀する揚穀排出装置8の下部を下部メタル9を介して取付ける。揚穀排出装置8の上部には揚穀排出装置8により揚穀された穀物を圃場近傍に停車させたトラック等のタンクに排出する排出オーガ10の基部を上下回動および旋回自在に取付ける。
【0007】
しかして、前記グレンタンク5は、上部タンク11と下部タンク12とに上下に分割形成し、上部タンク11は下部タンク12の外側に嵌合させ、グレンタンク5内には上部タンク11を上下させる上下機構13を設ける。上下機構13は上部を上部タンク11に軸支した一対の上部ロッド14の下部に、下部を下部タンク12側に軸支した一対の下部ロッド15の上部を軸部材16により夫々軸着する。一対の軸部材16と軸部材16には螺子軸17を螺合させる。螺子軸17は図示は省略するが、中間部より一方側と他方側と螺子溝の向きを反対に形成し、螺子軸17を同一方向に回転させたとき、一方の軸部材16と他方軸部材16は反対方向に移動する。したがって、螺子軸17を回転させると、上部ロッド14と下部ロッド15による上下機構13によって上部タンク11を下部タンク12に対して上下させる。18は上下用モータ、19は上下用モータ18の回り止め用機構、20はシール部材である。
【0008】
しかして、前記グレンタンク5は後側の任意位置中心に外側に回動自在に取付ける。その構成は任意であるが一例を示すと、前記グレンタンク5側の排出装置6の排出筒7と前記下部メタル9との間の軸着部に下部軸21を設け、該下部軸21を中心に前記グレンタンク5の下部が回動するように構成する。前記機体フレ−ム1の後部には、側面視コ型形状の後部支持フレーム22の下部を固定し、後部支持フレーム22の上部は前記揚穀排出装置8に固定し、該固定部分に上側回動支持部材23を設け、該上側回動支持部材23に前記グレンタンク5のステー24を上部軸25により軸着し、上部軸25は下部軸21と対応して下部軸21と同一軸心に位置するように設け、該上部軸25を中心に前記グレンタンク5の後側上部が回動する。
【0009】
しかして、前記グレンタンク5の回動をロックするロック装置26を設ける。ロック装置26は前記上部タンク11に係合フック27を設け、係合フック27は前記脱穀装置2からグレンタンク5に穀粒を供給する供給揚穀筒28の上部接続部29に設けた係合軸30に係合させる。前記係合フック27にはリンク等により構成した操作機構31を介して操作レバー32と連結し、操作レバー32は上部タンク11の壁面に取付ける。
前記供給揚穀筒28は下部筒33と上部筒34とに上下に分割し、上部筒34の排出口(図示省略)を有する前記上部接続部29をグレンタンク5の上部タンク11に接続する。上部接続部29とグレンタンク5の間には穀粒の漏れを防止する弾性部材35を介在させ、弾性部材35の弾力により係合フック27と係合軸30のロックを確実にすると共に、ロック装置26により上部接続部29とグレンタンク5の接続も確実にする。前記供給揚穀筒28内の一例を示すと、下部筒33に嵌合筒36を設け、嵌合筒36の角嵌合孔に角軸37を嵌合させ、角軸37に摺動筒38を摺動自在に複数嵌合させ、各摺動筒38に螺旋翼39を取付けると共に、各摺動筒38は下方の摺動筒38を牽引するようにし、最上位置の摺動筒38を上部筒34の上部に固定状態に取付け、上部筒34の上動により各摺動筒38を牽引してその間隔が大になるように構成している。
【0010】
また、脱穀装置の一番コンベア40と前記下部筒33との間に中間搬送部41を設け、前記供給揚穀筒28は下部筒33と上部筒34を略垂直に配置し、グレンタンク5に対応させて上下させるための前後の位置ずれを中間搬送部41により修正する(図10)。即ち、一番コンベア40と二番コンベア42との間隔を小にすると、二番戻し装置43と供給揚穀筒28が干渉するが、これらが干渉しないように配置すると共に、供給揚穀筒28の上部筒34の上下に対応させたものである。
しかして、前記供給揚穀筒28の上部接続部29にはステー44を設け、ステー44に上側回動アーム45の中間部を横軸回動自在に軸支し、上側回動アーム45の一端には牽引バネ46を係止し、上側回動アーム45の他端にはワイヤ47の一端を接続する(図11)。上部筒34の下部には取付部48を設け、取付部48に縦軸49によりブレーキ体50を取付ける。ブレーキ体50は下部筒33の外周を挟む一対の挟持体51と挟持体51に続いてX状に設けたアーム52とにより形成し、一方のアーム52に前記ワイヤ47の他端を挿通し、挿通したワイヤ47の先端(他端)を他方のアーム52に係止する。したがって、前記上側回動アーム45の他端が前記グレンタンク5側に当接しているときは、ワイヤ47が緩んでブレーキ体50の挟持体51は開くが、グレンタンク5を回動させると、上側回動アーム45が牽引バネ46により直ちに回動してワイヤ47を牽引し、ブレーキ体50の挟持体51が下部筒33の外周を挟んで上部筒34の下降を停止させる。
【0011】
しかして、前記グレンタンク5の下部タンク12は平面視四角形状に形成するが、前記グレンタンク5の上部タンク11の前記脱穀装置2側の内側板53と前記揚穀排出装置8側の後板54との角部分は、平面視切欠いて空間部55に形成する(図2、図15)。空間部55は収納位置の前記排出オーガ10と平面視重合する部分とし、上部タンク11を上動させたとき、上部タンク11と排出オーガ10との干渉を防止する。
しかして、グレンタンク5の前方に設けたキャビン56を設けた構成の場合は、前記上部タンク11は最大に上昇させてもキャビン56の上面より下方に位置するように構成する(図16、図17)。
しかして、前記下部タンク12の上部には穀粒センサ57を設け(図18)、少なくとも、穀粒センサ57が穀粒を検出しなくなると、上部タンク11を自動収納させる。即ち、上部タンク11の上下動は手動操作可能に構成しているが、上部タンク11を収納する下動については自動化したものであり、排出装置6の排出クラッチがオンのときに穀粒センサ57が穀粒を検出しなくなると、上部タンク11を自動収納させる。また、前記穀粒センサ57を利用して、穀粒センサ57が穀粒を検出したとき、自動的に上部タンク11を上動させることは勿論可能であり、このようにすると、収納および上動を自動化でき、操作性を向上させる。なお、上動は、最上位置あるいは段階的に上昇させる等任意である。
【0012】
しかして、また、前記穀粒センサ57の他の実施例では上部タンク11側に設け(図17、図20)、穀粒センサ57が穀粒を検出すると、自動的に上部タンク11を上動させる。この場合、上部タンク11は、穀粒センサ57の穀粒検出により所定範囲上昇させ、再び、穀粒センサ57が穀粒検出すると所定範囲上昇させることにより段階的に上昇させる。また、排出装置6の排出クラッチがオンのときに穀粒センサ57が穀粒を検出しなくなると、上部タンク11を自動下降させて、収納させることもできる。この場合の穀粒センサ57は、超音波センサ等の非接触型あるいは穀粒の接触する接触型の何れでもよい。
しかして、前記排出オーガ10の先端の排出口58の手前の下面には保護部材59を設ける。保護部材59は、少なくとも排出口58よりも下方であって排出オーガ10の長さ方向に長く形成し、トラックのトラックタンクに保護部材59が接触して排出オーガ10本体の接触を防止する。実施例では軸部材により、上向きコ型形状に形成する。また、図23および図24の実施例では、排出オーガ10は分割形成し、先端側が基部側に対して伸縮するように構成し、前記保護部材59は先端移動筒62に取付け、先端移動筒62の伸縮量より長く形成する。保護部材59は側面視先端側は縦直線状に形成し、中間部は横軸状に形成し、基部側は横向きU型形状に形成し、接触の際のショックを吸収する作用を期待する。また、前記排出口58の近傍には穀粒センサ61を設けているが、前記保護部材59は穀粒センサ61の下方に位置して保護し得るようにしている。
【0013】
63は先端移動筒62を伸縮させる伸縮用アクチュエータ、64は先端移動筒62内に設けた弾性体により形成した伸縮螺旋である。
しかして、刈取部4の一例を図25に示すと、75は分草体、76は引起装置、77は掻込装置、78は刈刃、79は株元側搬送装置、80は穂先側搬送装置、81は前記各搬送装置により搬送される搬送路の終端に設けた扱深さ調節装置、82は穀稈供給搬送装置83に引き継ぐ引継搬送装置である。前記穀稈供給搬送装置83は、前側レール84と後側レール85により構成した案内レール86により案内される搬送供給チエン87と挾扼杆88とにより構成する。前記案内レール86は、前記後側レール85に支持体89の上部を固定し、支持体89の下部は前方(略穀稈供給搬送装置83の始端部下方近傍)に位置させて機体の固定部に縦軸108により回動自在に取付ける。
【0014】
また、前側レール84の後端は刈取部4と扱胴の間(扱胴の前側)に位置させて後側レール85に上下回動自在に取付け、前側レール84には回動用アクチュエータ90のロッド91を取付け、回動用アクチュエータ90は前記支持体89に取付ける。したがって、搬送供給チエン87はその始端部を上下(スイング)させて引継搬送装置82との距離(間隔)を変更調節可能にすると共に、この上下回動機構と一緒に外開き回動するようにしている。
図28、29は、穀稈供給搬送装置83の他の実施例であり、前記脱穀装置3の側部に位置する主供給搬送装置92と該主供給搬送装置92の始端部と前記引継搬送装置82の終端側との間に設けた前側供給搬送装置93とに分割し、該前側供給搬送装置93の始端部は前記引継搬送装置82の終端部近傍に臨ませる。前側供給搬送装置93の終端部は、側面視前記主供給搬送装置92の始端部と重合するように、主供給搬送装置92の左右何れか一方側にオフセットさせて設け、かつ、前側供給搬送装置93の回転数を変更する。また、前記引継搬送装置82は、刈取部4の回転数が走行速度に応じて変速するので、これに同調して変速させる構成にすることもある。
【0015】
実施例では、主供給搬送装置92の前側歯車94と前側供給搬送装置93の後側歯車95を同じ軸96に設けて、回転を伝達すると共に、前側歯車94と後側歯車95の歯数を相違させて変速することにより、主供給搬送装置92は刈取部4および走行速度に同調し、前側供給搬送装置93は主供給搬送装置92に対して変速する。例えば、麦では前側供給搬送装置93を早くして脱穀装置の入口の詰まりを防止し、稲の場合は、同じにして穀稈こぼれを防止する。
なお、前側供給搬送装置93も、案内レール97を前記軸96中心に上下回動自在に設け、案内レール97に回動用アクチュエータ90のロッド91を取付け、始端部を上下回動(スイング)させて引継搬送装置82との距離(間隔)を変更調節可能にする。
【0016】
図30は、穀稈供給搬送装置83の他の実施例であり、前記実施例と同様に主供給搬送装置92と前側供給搬送装置93とに分割し、前記主供給搬送装置92は、所謂挾扼杆88と搬送供給チエン87により穀稈を挾持搬送するように構成し、前記挾扼杆88は脱穀装置3の上部カバーに設け、上部カバーの上方回動により搬送供給チエン87より退避させ、前記搬送供給チエン87は前後方向の案内レール86の前後に設けた歯車に掛け回す。
そして、本実施例では、前記前側供給搬送装置93は、更に、前記引継搬送装置82の終端部近傍に臨み、かつ、平面視前記主供給搬送装置92と同一直線状に主供給搬送装置92の前方に位置する始端側供給装置98と、該始端側供給装置98の終端側部と前記主供給搬送装置92の始端側部との夫々に臨んで重合する終端側供給装置99とにより構成する。
【0017】
しかして、前記始端側供給装置98のチエン101の上方には、穀稈を弾力的に始端側供給装置98に押し付ける挟持用案内ガイド100を設ける。挟持用案内ガイド100は前後方向の軸部材により形成し、挟持用案内ガイド100の先端は始端側供給装置98のチエン101の上方に臨ませ、挟持用案内ガイド100の基部は回動アーム102の先端に回動自在に軸103により軸着し、該軸103には挟持用案内ガイド100を常時下方回動するように付勢するバネ104を設ける。前記回動アーム102の基部は刈取部4の固定部に回動自在に軸着し、また、前記回動アーム102の中間部にはロッド105の上端を取付け、ロッド105の下部は扱深さ調節装置81の回動側のフレーム部分に取付け、扱深さ調節装置81の回動に連動して回動アーム102を回動させる。
【0018】
前記主供給搬送装置92は、始端側供給装置98の下方に設けた縦軸108を中心に縦軸回動自在に設け、前記脱穀装置3の側部を開放するように構成する。即ち、挟持用案内ガイド100を外さずに済む主供給搬送装置92を回動させて脱穀装置3の側部を開放し、脱穀装置3の側部開放を容易にする。
この場合、実施例では案内レール86の始端(前側)を側方に回動させるように構成し、前記機体フレーム1側には支持部材106を設け、該支持部材106に支持体89を前記縦軸108により回動自在に取付ける。
しかして、図32以下の刈取部4の実施例では、機体フレーム1から前方に伸びる上下回動自在の縦支持筒109の先端に取付け、該縦支持筒109の基部を前記機体フレーム1に回動自在に取付けることにより、上下動自在に構成され、前記縦支持筒109内に設けた伝動機構により機体側からの駆動が伝達される。前記縦支持筒109の先端には前記刈取部4の左右方向の下部伝動横筒110を取付け、該下部伝動横筒110の左側には上方に起立する側部伝動縦筒111を設け、図示は省略するが、前記下部伝動横筒110の右側には上方に起立する伝動機構を有しない側部支持フレームを設け、前記側部伝動縦筒111および側部支持フレームの上部を左右方向の上部伝動筒112により連結する。前記上部伝動筒112より垂下する下向き伝動筒113の下部には各引起装置76を取付ける。
【0019】
また、各引起装置76の後方には掻込装置77を設け、掻込装置77の縦伝動ケース114は取付部材115により固定部に固定し、ケース114には株元側搬送装置79の始端部を取付ける。株元側搬送装置79のフレーム(図示省略)には、穂先側搬送装置80を取付ける縦伝動筒116の下部を取付ける。前記穂先側搬送装置80は上下2段構成にし、そのうち上側穂先側搬送装置117は縦伝動筒116に軸118により回動自在に取付け、その始端側を上下するように構成し、長穀稈と短穀稈に対応させる。119は上下用アクチュエータである。また、上側穂先側搬送装置117の位置調節は扱深さ調節装置81と連動して行うと、搬送姿勢の乱れを発生させずに搬送できて好適である。この場合、扱深さ調節装置81の扱深さ調節用センサ120を利用して前記上下用アクチュエータ119を連動するようにすると、部品を増加させずに上側穂先側搬送装置117の位置調節を自動化でき好適である。
【0020】
また、上下用アクチュエータ119に替えてロッド121の位置を手動により切替えてもよい(図35、図36)。
また、前記上側穂先側搬送装置117は、下側穂先側搬送装置122に対して着脱自在に取付ける。実施例では、縦伝動筒116を分割形成し、上側穂先側搬送装置117を取付けた縦伝動筒116の下部を下側穂先側搬送装置122のケース123の上面の取付部124にピン125により着脱自在に取付ける。したがって、ピン125によりワンタッチの着脱が可能になる。
【0021】
(実施例の作用)
次に作用を述べる。
機体を前進させて穀稈を刈取り脱穀し、脱穀した穀粒がグレンタンク5に溜ると、圃場近傍に停車させたトラック等のタンクに排出する。
この場合、グレンタンク5は、上部タンク11と下部タンク12とに上下に分割形成し、グレンタンク5内には上部タンク11を上下させる上下機構13を設けているから、穀粒が溜ると、上部タンク11を下部タンク12に対して上動させる。したがって、穀粒が溜る前は上部タンク11を下げておけるので操縦部の後方視界を確保でき、作業性を向上させる。
上下機構13は、上部を上部タンク11に軸支した一対の上部ロッド14の下部に、下部を下部タンク12側に軸支した一対の下部ロッド15の上部を軸部材16により夫々軸着し、一対の軸部材16と軸部材16には螺子軸17を螺合させ、螺子軸17の一端に上下用モータ18を設けているから、上下用モータ18により螺子軸17を回転させると、一対の軸部材16と軸部材16を中央に寄せ、これにより上部ロッド14および下部ロッド15のリンク作用によって、上部タンク11は上動する。このとき、上部タンク11の周囲の内壁と下部タンク12の周囲の内壁にはシール部材20を設けているので、上部タンク11の上下に際して上部タンク11と下部タンク12との隙間に穀粒が入り込むことを防止する。
【0022】
しかして、前記グレンタンク5の下部タンク12は平面視四角形状に形成するが、前記グレンタンク5の上部タンク11の前記脱穀装置2側の内側板53と前記揚穀排出装置8側の後板54との角部分の収納位置の排出オーガ10と平面視重合する部分は平面視切欠いて空間部55に形成しているから、下部タンク12により容積を確保しつつ、上部タンク11を上動させたとき、排出オーガ10との干渉を防止する。したがって、作業性および操作性を向上させる。
しかして、グレンタンク5の前方に設けたキャビン56を設けた構成の場合は、前記上部タンク11は最大に上昇させてもキャビン56の上面より下方に位置するように構成しているから、操縦部の後方視界を確保でき、作業性を向上させる。
【0023】
しかして、脱穀した穀粒がグレンタンク5に溜ると、圃場近傍に停車させたトラック等のタンクに排出するが、下部タンク12の上部には穀粒センサ57を設け、少なくとも、穀粒センサ57が穀粒を検出しなくなると、上部タンク11を自動収納させるから、排出作業終了後に、上部タンク11を収納するのを忘れるのを防止でき、作業性および操作性を向上させる。即ち、排出装置6の排出クラッチがオンのときに穀粒センサ57が穀粒を検出しなくなると、上部タンク11を自動収納させる。また、前記穀粒センサ57を利用して穀粒センサ57が穀粒を検出したとき、自動的に上部タンク11を上動させるように構成すると、収納のみならず上部タンク11の上動をも自動化でき、操作性を向上させる。
【0024】
また、穀粒センサ57を上部タンク11側に設けた実施例では、、穀粒センサ57が穀粒を検出すると、自動的に上部タンク11を上動させるから、上部筒34は穀粒センサ57の穀粒検出により所定範囲上昇させ、再び、穀粒センサ57が穀粒検出すると所定範囲上昇させることにより段階的に上昇させる。したがって、操縦部の後方視界を確保でき、作業性を向上させる。また、排出装置6の排出クラッチがオンのときに穀粒センサ57が穀粒を検出しなくなると、上部筒34を自動下降させようにすると、収納も自動化でき、操作性を向上させる。
しかして、上部タンク11が下部タンク12に対して上動するが、脱穀装置2よりグレンタンク5に穀粒を供給する供給揚穀筒28は下部筒33と上部筒34とに上下に分割し、上部筒34の排出口(図示省略)を有する上部接続部29をグレンタンク5の上部タンク11に接続しているから、上部タンク11を上動させるだけで、これに牽引されて供給揚穀筒28の上部筒34も上動する。したがって、供給揚穀筒28の構成を簡素にでき、コストを低くできる。
【0025】
また、前記供給揚穀筒28は、脱穀装置の一番コンベア40と前記下部筒33とを中間搬送部41により接続しているから、下部筒33と上部筒34を略垂直に配置し、上部タンク11の上下に対応させて円滑に上下する。即ち、一番コンベア40と二番コンベア42の間隔を狭くしても、二番戻し装置43と供給揚穀筒28を干渉しないで配置させ、なおかつ、供給揚穀筒28を下部筒33と上部筒34の上下スライド構成にでき、全体をコンパクトにできる。
しかして、穀粒の排出作業が終了すると、グレンタンク5は、下部軸21と上部軸25を中心に外開き回動するから、グレンタンク5および脱穀装置2のメンテナンスを行う。
【0026】
この場合、グレンタンク5の機体フレ−ム1を上下させる上下機構13は、グレンタンク5内に設けているから、この上下機構13に関して一切の作業をすることなく、グレンタンク5を回動させることができ、回動作業を頗る容易にする。また、上下機構13を露出させていないので、グレンタンク5の支持構成および回動構成を簡素にすることができ、軽量化でき、コストも低くできる。
また、グレンタンク5は、下部タンク12を、固定部に上下に所定間隔おいて同一軸心に位置するように設けた下部軸21と上部軸25を中心に外側に回動自在に取付けているから、一層、上下する上部タンク11および上下動機構13と無縁に外側回動できる。したがって、場合によっては、上部タンク11を収納しないまま、外側回動させることも可能である。
また、下部タンク12は、下部軸21は前記グレンタンク5の排出装置6の排出筒7と、穀物排出用の揚穀排出装置8の下部に設けた下部メタル9との軸着部に、前記上部軸25は前記揚穀排出装置8側の上部に設けた上側回動支持部材23と下部タンク12との軸着部に、夫々設けているから、下部軸21と上部軸25は夫々強固に支持され、下部タンク12のみを回動自在に取付けていても、上部タンク11ごと下部タンク12は円滑、確実に支持しながら回動させる。即ち、揚穀排出装置8および下部メタル9の取付強度を補強することは、一例として示した図4および図5のように空間的余裕および配置の面から簡単であり、この取付強度を補強するだけで、グレンタンク5の回動機構の支持強度を向上させることが可能であり、グレンタンク5の容積に見合った支持強度を得ることができる。
しかして、上部タンク11の所定位置に係合フック27を設け、係合フック27は供給揚穀筒28の上部接続部29に設けた係合軸30に係合させ、係合フック27にはリンク等により構成した操作機構31を介して操作レバー32と連結しているから、操作レバー32を操作して係合フック27を外すと、ロック装置26のロックは解除され、グレンタンク5を回動させる。なお、グレンタンク5をもとに戻して係合フック27を係合軸30に係合させると、上部接続部29とグレンタンク5の間には弾性部材35を設けているから、弾性部材35により上部接続部29とグレンタンク5は密着して穀粒の漏れを防止するとともに、弾性部材35の弾力により係合フック27と係合軸30のロックを確実にする。
【0027】
しかして、供給揚穀筒28は、下部筒33に対して上部筒34を上部タンク11に対応させて上下させるため、上部筒34を上部接続部29を介してグレンタンク5に接続するが、グレンタンク5を外側回動させると、上部筒34は下降するが、上部接続部29にはステー44を設け、ステー44に回動アーム上側回動アーム45の中間部を軸支し、上側回動アーム45の一端には牽引バネ46を係止し、上側回動アーム45の他端にはワイヤ47の一端を接続し、ワイヤ47の他端は上部筒34の下部に設けたブレーキ体50に係止しているから、上側回動アーム45の他端がグレンタンク5側に当接しているときは、ワイヤ47が緩んでブレーキ体50の挟持体51は開くが、グレンタンク5を回動させると、上側回動アーム45が牽引バネ46により直ちに回動してワイヤ47を牽引し、ブレーキ体50の挟持体51が下部筒33の外周を挟んで上部筒34の下降を停止させる。したがって、操作することなく、上部筒34の可動を停止させる。
【0028】
しかして、前記排出オーガ10の先端の排出口58の手前の下面には、少なくとも排出口58よりも下方であって排出オーガ10の長さ方向に長く形成した保護部材59を設けているから、排出オーガ10をトラックのトラックタンクに位置合わせするとき、排出オーガ10が接触して本体の損傷を防止する。
また、実施例では軸部材により、側面視先端側は直線状に形成し、中間部は横軸状に形成し、基部側は横向きU型形状に形成しているから、接触の際のショックを吸収する作用を期待し、コストを低くしている。また、前記排出口58の近傍には穀粒センサ61を設けているが、前記保護部材59は穀粒センサ61の下方に位置させているから、穀粒センサ61も保護している。
【0029】
また、図23および図24の実施例では、排出オーガ10は長さ方向に複数に分割形成し、先端側が基部側に対して伸縮するように構成し、前記保護部材59は先端移動筒62に取付け、先端移動筒62の伸縮量より長く形成しているから、排出オーガ10の位置合わせを伸縮させることにより一層容易にすると共に、排出オーガ10の損傷を防止できる。
【0030】
しかして、前記穀稈供給搬送装置83の案内レール86は、前側レール84と後側レール85により構成し、後側レール85に支持体89の上部を固定し、支持体89の下部は機体の固定部に回動自在に取付けているから、案内レール86は後側を外開き回動させて、脱穀装置3の側部を開放し、メンテナンス作業を容易にする。この場合、支持体89と固定部の軸着部は略穀稈供給搬送装置83の始端部下方近傍に位置させているから、回動中心を前側に位置させることができ、案内レール86の後側を大きく開くことができる。
また、前側レール84の後端は刈取部4と扱胴の間に位置させ、後側レール85に対して前端を上下回動自在に取付け、前側レール84には回動用アクチュエータ90のロッド91を取付け、回動用アクチュエータ90は前記支持体89に取付けているから、穀稈供給搬送装置83はその始端部を上下(スイング)させて引継搬送装置82との距離(間隔)を変更調節でき、短稈の場合は上動させて確実に引継搬送でき、また、長穀稈の場合は穀稈供給搬送装置83の始端部を下降させて、搬送の流れを円滑にして、搬送姿勢を良好にでき、穀稈こぼれを防止できる。しかも、上下回動機構を支持体89に設けているから、案内レール86と一緒に回動させることができ、穀稈供給搬送装置83の外開き移動作業および操作を容易にでき、メンテナンス全体を容易にする。また、穀稈供給搬送装置83は直線状に形成しているから、構成が簡素であり、コストを低くできる。
【0031】
図29の穀稈供給搬送装置83の他の実施例では、前記脱穀装置3の側部に位置する主供給搬送装置92と該主供給搬送装置92の始端部と前記引継搬送装置82の終端側との間に設けた前側供給搬送装置93とに分割し、該前側供給搬送装置93の始端部は前記引継搬送装置82の終端部近傍に臨ませ、前側供給搬送装置93の終端部が側面視前記主供給搬送装置92の始端部と重合するように、平面視主供給搬送装置92の左右何れか一方側にオフセットさせて設け、かつ、前側供給搬送装置93の回転数を変更しているから、前側供給搬送装置93の始端部を前側歯車94の軸96中心に上下回動(スイング)させて引継搬送装置82との距離(間隔)を変更調節することにより、引継を良好にし、短穀稈および長穀稈の適応能力を向上させ、回転数を変更することにより穀稈のつまりや穀稈こぼれを防止する。
【0032】
図30の穀稈供給搬送装置83の他の実施例では、前側供給搬送装置93を更に引継搬送装置82の終端部近傍に臨み、かつ、平面視主供給搬送装置92と同一直線状の前方に位置する始端側供給装置98と、該始端側供給装置98の終端側部と前記主供給搬送装置92の始端側部との夫々に臨んで重合する終端側供給装置99とにより構成しているから、一層、引継が良好になる。即ち、終端側供給装置99が挟持搬送している状態で主供給搬送装置92が穀稈を受け取るので、搬送姿勢を乱さず、良好となる。
この場合、前記始端側供給装置98および/または終端側供給装置99のチエン101の上方には、穀稈を弾力的にチエン101に押し付ける挟持用案内ガイド100を設け、前側供給搬送装置93に対して主供給搬送装置92を、始端側供給装置98の下方に設けた縦軸縦軸108を中心に縦軸回動自在に設けているから、挟持用案内ガイド100を外す面倒な作業をすることなく脱穀装置3の側部を開放できる。また、縦軸108を中心に縦軸回動させるので、脱穀装置3の側部を大きく開放することができ、また、穀稈供給搬送装置83全体を側方回動させるのに比して前側供給搬送装置93の長さ分短い主供給搬送装置92を側方回動させるので、回動スペースを狭くでき、狭いスペースでも回動させて開放することができる。なお、主供給搬送装置92の挾扼杆88は脱穀装置3の上部カバーの上方回動により搬送供給チエン87より退避させるので、従来と同様な手間で行える。
【0033】
また、前記挟持用案内ガイド100は前後方向の軸部材により形成し、挟持用案内ガイド100の基部は回動アーム102の先端に回動自在に軸103により軸着し、該軸103には挟持用案内ガイド100を常時下方回動するように付勢するバネ104を設けている構成であるから、軸103の部分と回動アーム102の基部の2か所で回動するので、挟持用案内ガイド100は常に上方に弾力的に穀稈を押し付けるように追随させることができる。
【0034】
なお、前側供給搬送装置93は、始端側供給装置98と終端側供給装置99とにより構成し、前側供給搬送装置93は前記引継搬送装置82と同一搬送速度にするとともに、走行速度と同調して変速するように構成すると、走行速度と同調して引継搬送装置82により円滑に搬送された穀稈の株元は、引き続き同じ搬送速度の始端側供給装置98にのみ引き継がれて搬送され、次ぎに、次ぎに、始端側供給装置98に株元が挟持搬送されている状態で、これよりやや穂先側が終端側供給装置99に同じ搬送速度で引き継がれる。したがって、搬送姿勢が引継搬送装置82から変化する状態でも前側供給搬送装置93は始端側供給装置98と終端側供給装置99により確実に搬送する。特に、主供給搬送装置92の前側に始端側供給装置98を設けているから、引継搬送装置82からの引継が良好になる。即ち、搬送速度の相違する前側供給搬送装置93と主供給搬送装置92とに引継搬送装置82から直接引き継ぐことによる不具合を防止する。また、本実施例の終端側供給装置99と主供給搬送装置92とでは搬送速度が相違するが、既に搬送姿勢は横向きになっており、終端側供給装置99により搬送されたものをそのまま引き継ぐことになるので、搬送乱れは生じない。
【0035】
しかして、前記刈取部4は、株元側搬送装置79の上方に上下2段の穂先側搬送装置80を取付けて構成し、穂先側搬送装置80のうち上側穂先側搬送装置117は縦伝動筒116に軸118により回動自在に取付け、その始端側を上下するように構成しているから、穀稈の長短に合わせて、穂先の取り込み掃き出し位置を変更でき、条件適応性が向上する。
また、上側穂先側搬送装置117の位置調節は扱深さ調節装置81と連動して行うと、搬送姿勢の乱れを発生させずに搬送できて好適である。この場合、扱深さ調節装置81の扱深さ調節用センサ120を利用して前記上下用アクチュエータ119を連動するようにすると、部品を増加させずに上側穂先側搬送装置117の位置調節を自動化でき好適である。例えば、長穀稈の場合先端を下げ前傾させて穀稈を下から上へ扱き上げ前に垂れている姿勢を直線的な姿勢に変更できる。また、短穀稈の場合下の搬送装置と略並行にさせると、穂先の搬送を確実にでき、全体の搬送姿勢を良好にさせる。このとき、刈取部4の所望位置に穀稈長さ検出手段を設けると、この検出信号により上下用アクチュエータ119を無段階に作動させて、調節できる。
【0036】
また、上下用アクチュエータ119に替えてロッド121の位置を手動により切替える構成にすると、安価にできる(図35、図36)。
しかして、また、上側穂先側搬送装置117は、下側穂先側搬送装置122に対して着脱自在に取付けているから、上側穂先側搬送装置117は穀稈が長いときに使用することにより搬送を確実にし、また、穀稈が短いときは外すことにより短穀稈の穂先の接触抵抗を減少させて、脱粒を防止してロス発生を防止する。また、前記縦伝動筒116は下側穂先側搬送装置122を挟んで上下に分割形成し、上側穂先側搬送装置117を取付けた縦伝動筒116の下部を下側穂先側搬送装置122のケース123の上面の取付部124にピン125により着脱自在に取付けているから、ピン125によりワンタッチの着脱ができ、機種対応の組立作業を容易にするだけでなく、メンテナンスも容易になる。

本発明は、前記グレンタンク5の前方にキャビン56を設け、前記上部タンク11は最大に上昇させてもキャビン56の上面より下方に位置するように構成した穀粒貯留装置としたものであるから、操縦部の後方視界を確保でき、作業性を向上させる。
本発明は、前記下部タンク12の上部には穀粒センサ57を設け、少なくとも、穀粒センサ57が穀粒を検出しなくなると、上部タンク11を自動収納するように構成した穀粒貯留装置としたものであるから、排出作業終了後に、上部タンク11を収納するのを忘れるのを防止でき、作業性および操作性を向上させる。
本発明は、前記上部タンク11の上部には穀粒センサ57を設け、該穀粒センサ57の穀粒検出または不検出により上部タンク11を自動的に上動または下動するようにした穀粒貯留装置としたものであるから、穀粒検出または不検出により上部タンク11を自動的に上動または下動させるので、上下動を自動化でき、操作性および作業性を向上させる。

(Operation of Example)
Next, the operation will be described.
The machine body is moved forward to cut and thresh the cereal, and when the threshed grains are accumulated in the glen tank 5, they are discharged to a tank such as a truck stopped near the field.
In this case, the Glen tank 5 is divided into an upper tank 11 and a lower tank 12 and is provided with a vertical mechanism 13 that moves the upper tank 11 up and down in the Glen tank 5. The upper tank 11 is moved up with respect to the lower tank 12. Therefore, since the upper tank 11 can be lowered before the grains are collected, the rear view of the control unit can be secured, and the workability is improved.
The vertical mechanism 13 is pivotally attached to the lower part of the pair of upper rods 14 pivotally supported on the upper tank 11 and the upper part of the pair of lower rods 15 pivotally supported on the lower tank 12 side by the shaft member 16. Since the screw shaft 17 is screwed into the pair of shaft members 16 and the shaft member 16 and the vertical motor 18 is provided at one end of the screw shaft 17, when the screw shaft 17 is rotated by the vertical motor 18, The shaft member 16 and the shaft member 16 are moved toward the center, whereby the upper tank 11 is moved upward by the link action of the upper rod 14 and the lower rod 15. At this time, since the sealing member 20 is provided on the inner wall around the upper tank 11 and the inner wall around the lower tank 12, the grains enter the gap between the upper tank 11 and the lower tank 12 when the upper tank 11 is moved up and down. To prevent that.
[0022]
Thus, although the lower tank 12 of the Glen tank 5 is formed in a square shape in plan view, the inner plate 53 on the threshing device 2 side and the rear plate on the mashing discharge device 8 side of the upper tank 11 of the Glen tank 5. The portion that overlaps with the discharge auger 10 at the storage position at the corner portion 54 in plan view is cut out in plan view and formed in the space portion 55, so that the upper tank 11 is moved upward while securing the volume by the lower tank 12. When this occurs, interference with the discharge auger 10 is prevented. Therefore, workability and operability are improved.
Therefore, in the case of the configuration in which the cabin 56 provided in front of the Glen tank 5 is provided, the upper tank 11 is configured to be positioned below the upper surface of the cabin 56 even if the upper tank 11 is raised to the maximum. The rear view of the part can be secured and workability is improved.
[0023]
Thus, when the threshed grains are accumulated in the glen tank 5, they are discharged to a tank such as a truck stopped near the field. A grain sensor 57 is provided at the upper part of the lower tank 12, and at least the grain sensor 57 is provided. When the grain is no longer detected, the upper tank 11 is automatically stored, so that it is possible to prevent the user from forgetting to store the upper tank 11 after the discharge operation is completed, thereby improving workability and operability. That is, when the grain sensor 57 stops detecting the grain when the ejection clutch of the ejection device 6 is on, the upper tank 11 is automatically stored. In addition, when the grain sensor 57 detects the grain using the grain sensor 57, the upper tank 11 is automatically moved up. It can be automated and improves operability.
[0024]
In the embodiment in which the grain sensor 57 is provided on the upper tank 11 side, when the grain sensor 57 detects the grain, the upper tank 11 is automatically moved up. When the grain sensor 57 detects the grain again, the predetermined range is raised, and the predetermined range is raised to raise it stepwise. Therefore, the rear view of the control unit can be secured and workability is improved. Further, if the grain sensor 57 does not detect the grain when the ejection clutch of the ejection device 6 is on, the upper cylinder 34 can be automatically lowered, so that the storage can be automated and the operability is improved.
Thus, although the upper tank 11 moves up relative to the lower tank 12, the supply cereal cylinder 28 that supplies the grain from the threshing device 2 to the grain tank 5 is divided into a lower cylinder 33 and an upper cylinder 34. Since the upper connecting portion 29 having a discharge port (not shown) of the upper cylinder 34 is connected to the upper tank 11 of the Glen tank 5, the upper cereal 11 is pulled up and fed by simply moving the upper tank 11 up. The upper cylinder 34 of the cylinder 28 also moves up. Therefore, the structure of the supply cereal cylinder 28 can be simplified and the cost can be reduced.
[0025]
Moreover, since the said supply cereal cylinder 28 has connected the most conveyor 40 of the threshing apparatus, and the said lower cylinder 33 by the intermediate conveyance part 41, arrange | positions the lower cylinder 33 and the upper cylinder 34 substantially perpendicularly, and is an upper part. It moves up and down smoothly corresponding to the upper and lower of the tank 11. That is, even if the interval between the first conveyor 40 and the second conveyor 42 is narrowed, the second returning device 43 and the supply cereal cylinder 28 are arranged without interfering with each other, and the supply cereal cylinder 28 is arranged with the lower cylinder 33 and the upper part. The cylinder 34 can be configured to slide up and down, and the whole can be made compact.
Thus, when the grain discharging operation is completed, the Glen tank 5 rotates outwardly about the lower shaft 21 and the upper shaft 25, so that the Glen tank 5 and the threshing apparatus 2 are maintained.
[0026]
In this case, since the vertical mechanism 13 for moving up and down the fuselage frame 1 of the Glen tank 5 is provided in the Glen tank 5, the Glen tank 5 is rotated without performing any work on the vertical mechanism 13. This makes it easier to turn. Moreover, since the vertical mechanism 13 is not exposed, the support structure and the rotation structure of the Glen tank 5 can be simplified, the weight can be reduced, and the cost can be reduced.
Further, the Glen tank 5 has a lower tank 12 attached to a fixed portion so as to be pivotable outwardly around a lower shaft 21 and an upper shaft 25 provided so as to be positioned on the same axis at predetermined intervals in the vertical direction. Therefore, it is possible to rotate outwardly without any relation to the upper tank 11 and the vertical movement mechanism 13 that move up and down. Therefore, in some cases, it is possible to rotate the upper tank 11 without storing it.
The lower tank 12 has a lower shaft 21 attached to a shaft attachment portion between a discharge cylinder 7 of the discharge device 6 of the grain tank 5 and a lower metal 9 provided at a lower portion of the cereal discharge device 8 for discharging the grain. Since the upper shaft 25 is provided at the shaft attachment portion between the upper turning support member 23 and the lower tank 12 provided at the upper portion on the side of the cereal discharger 8, the lower shaft 21 and the upper shaft 25 are firmly attached to each other. Even if only the lower tank 12 is rotatably supported, the lower tank 12 together with the upper tank 11 is rotated while being supported smoothly and reliably. That is, it is easy to reinforce the attachment strength of the cereal discharge device 8 and the lower metal 9 in terms of space and arrangement as shown in FIG. 4 and FIG. 5 shown as an example, and this attachment strength is reinforced. As a result, the support strength of the rotation mechanism of the Glen tank 5 can be improved, and the support strength commensurate with the volume of the Glen tank 5 can be obtained.
Thus, an engagement hook 27 is provided at a predetermined position of the upper tank 11, and the engagement hook 27 is engaged with an engagement shaft 30 provided at the upper connection portion 29 of the supply milling cylinder 28. Since it is connected to the operation lever 32 via the operation mechanism 31 constituted by a link or the like, when the engagement hook 27 is removed by operating the operation lever 32, the lock of the lock device 26 is released and the glen tank 5 is rotated. Move. When the Glen tank 5 is returned to its original position and the engagement hook 27 is engaged with the engagement shaft 30, the elastic member 35 is provided between the upper connecting portion 29 and the Glen tank 5, so that the elastic member 35 Thus, the upper connecting portion 29 and the Glen tank 5 are brought into close contact with each other to prevent the leakage of the grains, and the elastic force of the elastic member 35 ensures the locking of the engaging hook 27 and the engaging shaft 30.
[0027]
Thus, the supply milling cylinder 28 connects the upper cylinder 34 to the glen tank 5 via the upper connection part 29 in order to move the upper cylinder 34 up and down relative to the lower cylinder 33 in correspondence with the upper tank 11. When the Glen tank 5 is rotated outward, the upper tube 34 is lowered, but the upper connection portion 29 is provided with a stay 44, and an intermediate portion of the rotation arm upper rotation arm 45 is pivotally supported on the stay 44. A traction spring 46 is locked to one end of the moving arm 45, one end of the wire 47 is connected to the other end of the upper turning arm 45, and the other end of the wire 47 is provided at the lower portion of the upper cylinder 34. Therefore, when the other end of the upper rotating arm 45 is in contact with the Glen tank 5 side, the wire 47 is loosened and the holding body 51 of the brake body 50 is opened, but the Glen tank 5 is rotated. When it is moved, the upper turning arm 45 is pulled. Leading the wire 47 immediately rotates the value 46, holding member 51 of the brake member 50 stops the downward movement of the upper cylinder 34 across the outer periphery of the lower cylinder 33. Therefore, the movement of the upper cylinder 34 is stopped without operation.
[0028]
Therefore, a protective member 59 formed at least below the discharge port 58 and long in the length direction of the discharge auger 10 is provided on the lower surface of the front end of the discharge auger 10 before the discharge port 58. When aligning the discharge auger 10 with the truck tank of the truck, the discharge auger 10 contacts to prevent damage to the body.
Further, in the embodiment, the shaft member is formed in a straight shape on the front end side in a side view, the intermediate portion is formed in a horizontal shaft shape, and the base side is formed in a lateral U shape, so that a shock at the time of contact is formed. Expected to absorb, lowering costs. Moreover, although the grain sensor 61 is provided in the vicinity of the said discharge port 58, since the said protection member 59 is located below the grain sensor 61, the grain sensor 61 is also protected.
[0029]
In the embodiment of FIGS. 23 and 24, the discharge auger 10 is divided into a plurality of portions in the length direction, the tip end side is configured to expand and contract with respect to the base side, and the protection member 59 is attached to the tip moving cylinder 62. Since it is formed longer than the amount of expansion and contraction of the attachment and tip moving cylinder 62, the alignment of the discharge auger 10 can be further expanded and contracted, and damage to the discharge auger 10 can be prevented.
[0030]
Thus, the guide rail 86 of the grain supply and transfer device 83 is constituted by the front rail 84 and the rear rail 85, and the upper portion of the support body 89 is fixed to the rear rail 85, and the lower portion of the support body 89 is the machine body. Since the guide rail 86 is pivotably attached to the fixed part, the rear side is pivoted outwardly to open the side part of the threshing device 3, thereby facilitating maintenance work. In this case, since the support body 89 and the fixed part of the fixed part are positioned in the vicinity of the lower part of the starting end of the grain supply and transfer device 83, the center of rotation can be positioned on the front side, and the rear of the guide rail 86. The side can be opened wide.
The rear end of the front rail 84 is positioned between the cutting unit 4 and the barrel, and the front end is attached to the rear rail 85 so as to be rotatable up and down. The rod 91 of the rotation actuator 90 is attached to the front rail 84. Since the attachment / rotation actuator 90 is attached to the support 89, the cereal supply / conveyance device 83 can change and adjust the distance (interval) with the takeover conveyance device 82 by moving its starting end up and down (swing). In the case of cocoons, it can be moved up and transferred reliably, and in the case of long cereals, the starting end of the cereal supply and transfer device 83 can be lowered to smooth the flow of conveyance and improve the conveying posture. Can prevent grain spillage. In addition, since the support 89 is provided with a vertical rotation mechanism, it can be rotated together with the guide rail 86, the work of opening and moving the cereal supply and transfer device 83 and the operation can be facilitated, and the entire maintenance can be performed. make it easier. Further, since the cereal supply / conveyance device 83 is formed in a straight line, the configuration is simple and the cost can be reduced.

In another embodiment of the cereal supply and transfer device 83 of FIG. 29, the main supply and transfer device 92 located at the side of the threshing device 3, the start end of the main supply and transfer device 92, and the end side of the takeover transfer device 82 The front supply / conveyance device 93 is divided between the front supply / conveyance device 93, the front end of the front supply / conveyance device 93 faces the end of the takeover / conveyance device 82, and the end of the front supply / conveyance device 93 is viewed from the side. Since it is offset from either the left or right side of the main supply / conveyor device 92 in plan view and overlaps with the starting end of the main supply / conveyor device 92, and the rotational speed of the front supply / conveyor device 93 is changed. By changing the distance (interval) with the take-up and transfer device 82 by rotating the starting end of the front-side supply and transfer device 93 up and down (swing) around the shaft 96 of the front gear 94, it is possible to improve the take-over. Improve the adaptability of cocoons and long-grain potatoes It is allowed, by changing the rotational speed to prevent clogging or culms spill culms.
[0032]
In another embodiment of the grain supply / conveyance device 83 of FIG. 30, the front supply / conveyance device 93 further faces the vicinity of the terminal end portion of the takeover conveyance device 82 and is in front of the main supply / conveyance device 92 in a straight line. Since it is configured by a start-side supply device 98 that is positioned, and a termination-side supply device 99 that superposes each of the end-side portion of the start-end-side supply device 98 and the start-end side portion of the main supply / conveyance device 92. Furthermore, the takeover becomes better. That is, since the main supply transport device 92 receives the cereal while the end-side supply device 99 is nipping and transporting, the transport posture is not disturbed, which is favorable.
In this case, a holding guide 100 is provided above the chain 101 of the start side supply device 98 and / or the end side supply device 99 to press the cereals to the chain 101 elastically. Since the main supply / conveyance device 92 is provided so as to be rotatable about the vertical axis 108 provided below the start side supply device 98, the troublesome work of removing the holding guide 100 is performed. The side part of the threshing device 3 can be opened. Moreover, since the vertical axis is rotated about the vertical axis 108, the side portion of the threshing device 3 can be opened widely, and the front side compared to rotating the whole cereal supply and transfer device 83 sideways. Since the main supply / conveyance device 92, which is shorter by the length of the supply / conveyance device 93, is rotated sideways, the rotation space can be narrowed and can be rotated and opened even in a narrow space. In addition, since the eaves 88 of the main supply / conveyance device 92 are retracted from the conveyance / supply chain 87 by the upward rotation of the upper cover of the threshing device 3, it can be performed with the same effort as in the prior art.
[0033]
Further, the holding guide guide 100 is formed by a shaft member in the front-rear direction, and the base of the holding guide guide 100 is pivotally attached to the distal end of the rotating arm 102 by a shaft 103, and is held by the shaft 103. Since the spring 104 that urges the guide guide 100 to always rotate downward is provided, the guide guide 100 is rotated at two places, that is, the shaft 103 and the base of the rotary arm 102. The guide 100 can always be followed so as to elastically press the cereals upward.
[0034]
The front supply / conveyance device 93 includes a start-side supply device 98 and a termination-side supply device 99. The front-side supply / conveyance device 93 has the same conveyance speed as that of the takeover conveyance device 82 and is synchronized with the traveling speed. When configured to shift, the stock of cereal grains that are smoothly conveyed by the takeover conveying device 82 in synchronism with the traveling speed are continuously taken over and conveyed only to the starting end side supply device 98 having the same conveying speed, and then Next, in a state where the stock is held and conveyed by the start side supply device 98, the tip side is slightly handed over to the end side supply device 99 at the same conveyance speed. Therefore, even when the transport posture changes from the takeover transport device 82, the front supply transport device 93 is reliably transported by the start side supply device 98 and the end side supply device 99. In particular, since the start side supply device 98 is provided on the front side of the main supply conveyance device 92, the takeover from the takeover conveyance device 82 is improved. That is, it is possible to prevent problems caused by directly taking over from the take-up conveyance device 82 to the front supply conveyance device 93 and the main supply conveyance device 92 having different conveyance speeds. In addition, although the conveyance speed is different between the terminal side supply device 99 and the main supply conveyance device 92 of the present embodiment, the conveyance posture is already in the horizontal direction, and the one conveyed by the termination side supply device 99 is taken over as it is. Therefore, the conveyance disturbance does not occur.
[0035]
Thus, the cutting unit 4 is configured by attaching the upper and lower two-stage tip side transport device 80 above the stock source side transport device 79, and the upper tip side transport device 117 of the tip side transport device 80 is a vertical transmission cylinder. Since the shaft 118 is rotatably attached to the shaft 118 and its starting end side is moved up and down, the position of picking up and discharging the tip can be changed according to the length of the cereal and the condition adaptability is improved.
Further, when the position adjustment of the upper tip side transfer device 117 is performed in conjunction with the handling depth adjustment device 81, it is preferable that the transfer can be performed without causing a disturbance of the transfer posture. In this case, if the up / down actuator 119 is interlocked using the handling depth adjustment sensor 120 of the handling depth adjustment device 81, the position adjustment of the upper tip side transfer device 117 is automated without increasing the number of parts. This is preferable. For example, in the case of a long corn straw, the tip is lowered and tilted forward, so that the posture of the corn straw hanging from the bottom to the top can be changed to a linear posture. Moreover, when it is made substantially parallel with the lower conveying apparatus in the case of a short grain candy, conveyance of a tip can be ensured and the whole conveyance attitude | position is made favorable. At this time, if the culm length detection means is provided at a desired position of the cutting unit 4, the vertical actuator 119 can be operated steplessly and adjusted by this detection signal.
[0036]
Further, if the position of the rod 121 is switched manually instead of the vertical actuator 119, the cost can be reduced (FIGS. 35 and 36).
In addition, since the upper tip side transport device 117 is detachably attached to the lower tip side transport device 122, the upper tip side transport device 117 is used for transporting when the cereal is long. It is ensured, and when the culm is short, it is removed to reduce the contact resistance of the tip of the short culm, thereby preventing threshing and preventing loss. The vertical transmission cylinder 116 is divided into upper and lower parts with the lower tip side transfer device 122 interposed therebetween, and the lower portion of the vertical transmission cylinder 116 to which the upper tip side transfer device 117 is attached is the case 123 of the lower tip side transfer device 122. Since the pin 125 is detachably attached to the attachment portion 124 on the upper surface of the, a one-touch attachment / detachment can be performed with the pin 125, and not only assembly work corresponding to the model is facilitated but also maintenance is facilitated.
