【0007】
図6乃至図10にも示す如く、前記補助搬送チェン(35)の送り作用側に配設する挾扼搬送ガイド(39)を、本体側に固定するガイド受台(40)にブラケット(41)・ロッドガイド台(42)・挾扼ガイド(43)を介しチェン(35)との間隔を変更自在に支持させるもので、前記ブラケット(41)とガイド台(42)はそれぞれ断面冂形状に形成し、ガイド台(42)の両側壁部(42b)の左右両端間をロッド(39)が貫通してガイド台(42)にロッド(39)が支持されるのに対し、前記ブラケット(41)とガイド台(42)とは交叉させ、ブラケット(41)の上側壁部(41b)にガイド台(42)の上側壁部(42a)の左右略中央を長孔(44)及びボルト(45)を介しロッド(39)の長手方向に調節自在に固定させ、前記ガイド台(42)とロッド(43)間には挾扼バネ(46)を介在させて、搬送ガイド(39)に常時はチェン(35)方向の張り力を付勢するように構成している。
【0008】
また、前記ガイド受台(40)は逆冂形に形成し、立上り両側壁部(40b)の一方を補助ガイドフレーム(47)を介し本体側に連結支持させ、両側壁部(40b)の内側面にブラケット(41)の両側壁部(41b)下端側を接合させ、該両側壁部(41b)に形成するスライド用長孔(48)を、受台両側壁部(40b)間を挿通させる支点軸(49)に係合させ、受台(40)に長孔(48)の範囲内でブラケット(41)を移動自在に連結させている。
【0009】
さらに、前記ブラケット両側壁部(41b)内側面の長孔(48)周囲に規制板(50)を固定させ、受台(40)の両側壁部(40b)間に横設する上向き防止板(51)と規制板(50)一端側の上向き規制部(50a)との係合によって前記支点軸(49)を中心としたブラケット(41)の反時計方向の回動を阻止させると共に、受台両側壁部(40b)上端縁とガイド台(42)一側の側壁部(42b)下端縁との当接(図9中A部)によって前記支点軸(49)を中心としたブラケット(41)の時計方向の回動を阻止するように構成している。
【0010】
またさらに、前記ガイド受台(40)にはロック軸(52)を有するロックレバー(53)を設けて、前記搬送ガイド(39)の挾扼解除をレバー(53)によって行うようにしたもので、前記受台(40)の防止板(51)とは反対側の底壁部(40a)略中央の軸受部(54)に軸(55)を介してロックレバー(53)基端の軸ボス(56)を上下回動自在に支持させ、前記ロック軸(52)を軸ボス(56)に固設させ、前記ロックレバー(53)を起立保持させてのロック操作時、前記規制板(50)の後退規制部(50b)を挾んだ支点軸(49)の対向位置にロック軸(52)を位置保持させる状態とさせて、ブラケット(41)のチェン(35)より反対方向へのスライドを規制する一方、前記ロックレバー(53)を横水平状に傾倒させてのロック解除操作時、軸(55)を中心としてロック軸(52)を軸(55)の上方位置に移動させて、この軸(55)による規制部(50b)に対する規制を解除させてブラケット(41)を長孔(44)の範囲内で最大チェン(35)から離れる方向に移動させるように構成している。つまり図9乃至図10に示す如く、前記規制板(50)の後退規制部(50b)は、上向き規制部(50a)の反対側位置にあって、長孔(48)を囲む状態で且つ軸(55)及び軸ボス(56)に干渉させることなく間隔を空けて両側壁部(41b)近傍のみに設けると共に、前記ロック軸(52)は規制部(50b)の後退面に干渉させるように規制板(50)の横巾と略同一に設けて、前記レバー(53)のロック操作時には規制部(50b)の後退面をロック軸(52)に当接させてその後退を規制する一方、レバー(53)のロック解除操作時には規制部(50b)の後退面とロック軸(52)の当接解除によってその後退を許容するように構成したものである。なおロック操作時にあってはロック軸(52)の下側には規制板(50)の下側規制部(50c)の延長端が位置する状態となって、ロックレバー(53)のロック解除方向とは反対側方向の回動が規制されるものである。
【0011】
また、前記ロックレバー(53)のロック操作時、該レバー(55)を起立位置で保持するレバーストッパ(57)を、ガイド台(42)の上方位置に設けるもので、本体側にフレーム(58)及び取付板(59)などを介し固設するストッパ座(60)に、軸(61)を介してU形状のストッパ(57)基端を回動自在に支持させ、ストッパ(57)の開脚部間で、ストッパ(57)を横水平姿勢位置まで回動させて、開脚先端部をストッパ座(60)のストッパピン(62)に係止させるとき、レバー(53)をこのロック位置で保持するように構成している。
【0012】
前記支点軸(49)は、受台側壁部(40b)より突出させる外側端に枢着板(63)を固設していて、受台(40)に固設するボルトボス(64)にボルト(65)を介し枢着板(63)を固定することによって、支点軸(49)の取付けを行うように設けて、ボルト(65)による枢着板(63)の着脱操作によって支点軸(49)の取付け及び取外し可能とさせるように構成している。
【0013】
而して刈取作業中に、補助搬送チェン(35)と搬送ガイド(39)間に穀稈の詰まり事故などが発生し、搬送ガイド(39)が稈の詰まり圧によってこの反対方向にスライドし、挾扼バネ(46)のバネ圧も大となるときには、前記レバー(53)に対するストッパ(57)のロック解除を行って、レバー(53)を起立位置より傾倒させ、前記ブラケット(41)に対するロック軸(52)の規制を解除させて、長孔(48)のストローク分ブラケット(41)と一体に搬送ガイド(39)を搬送チェン(35)より後退させる状態とさせて、穀稈に対するバネ(46)の押圧力(詰まった穀稈が少ない時には稈とガイド(39)との間には隙間ができる)を弱めて稈を容易に取除き可能とさせるものである。このようにロックレバー(53)のみの操作によって搬送ガイド(39)のワンタッチ解除を可能とさせて、詰まり稈の取除き作業などの能率向上化が図れるものである。
【0014】
また、搬送ガイド(39)の取外し時においても、搬送ガイド(39)の最後退位置で前記ボルト(65)による枢着板(63)の取外し操作で支点軸(49)をブラケット(41)より引抜くことによって、ブラケット(41)と一体の搬送ガイド(39)の取外しが容易に行えるものである。
【0015】
図11乃至図13のものは、レバーのみによるワンタッチ操作で搬送ガイド(39)と一体にガイド台(42)を補助ガイドフレーム(47)のガイド受台(40)より取外して詰まり稈の取除きを容易とさせるように構成例を示すもので、補助ガイドフレーム(47)のレバー取付板(66)にレバー軸(67)を介して鋏状のロック解除レバー(68)を設け、解除レバー(68)の握り操作部(68a)の反対側端に、ガイド台(42)及び受台(40)の差込み孔に係合挿入させる差込みピン(69)を回動且つ移動自在に設けて、レバー操作によって該ピン(69)でガイド台(42)と受台(40)とを一体連結させるときロック状態とさせる一方、ピン(69)を引抜くとき搬送ガイド(39)と一体にガイド台(42)を受台(40)より分離させて詰まり稈の取除きを行うように構成したものである。
【0016】
【発明の効果】
本発明では、受台に底壁部及び側壁部を設け、同側壁部に支点軸を抜き差し自在に取り付ける一方、ガイド台の上壁部にブラケットを介して後退規制部を設けるとともに、同後退規制部は、ガイド台の上壁部下方で受台の底壁部上方にて前記支点軸に係合させて、搬送チェンに搬送ガイドが近づく前進方向と、同搬送チェンから搬送ガイドが離れる後退方向とに上記支点軸を介して移動可能となし、同後退規制部にはロック軸を当接・解除自在に係合させて、後退規制部の後退方向への移動をロック・解除自在となし、さらに、前記支点軸を抜き差しすることにより、後退規制部との係合を解除して、同後退規制部を支持する前記ガイド台と受台とを係脱自在に連結させるようにしている。
このようにして、ロック軸を後退規制部から当接解除して、同後退規制部の後退方向への移動をロック解除することにより、同後退規制部を支持するガイド台に取り付けた搬送ガイドを搬送チェンから離れる後退方向に移動させることができる。
さらには、支点軸を引き抜くことにより、後退規制部との係合を解除して、同後退規制部を支持するガイド台を受台から離脱させて、同ガイド台に取り付けた搬送ガイドを搬送チェンから離隔させることができる。
従って、搬送ガイドと搬送チェンとの間の詰まり稈の取り除き作業などを容易にかつ確実に行うことができる。
