Description
また、各繰り出し部には左右方向に伸延する繰り出し作動軸を貫通状態に挿通して、各繰り出し部を繰り出し作動させるようにしている。ここで、繰り出し作動軸は走行装置に設けた動力取出軸に連動連結している。
そして、かかる施肥装置は、乗用田植機の走行装置に設けた座席の背後に左右方向に横長状に載設することで、各排出部を施肥装置の左右側端部に配置することができるため、オペレータは走行装置に搭乗して両可動側施肥部を略水直に跳ね上げた排出姿勢となすことで、各排出部を通して排出作業を楽に行うことができる。この際、走行装置の左右外側方位置で下方へ指向した各排出部の直下方位置に回収容器を配置しておけば、同回収容器内に流下状態に排出される残留肥料を楽に回収することができる。また、排出ホースを繰り出し部に接続することなく排出作業を行うことができるため、従来のように各繰り出し部に接続した排出ホースの煩雑な取り回しに苦慮する必要性がない。
そして、一側可動側施肥部の繰り出し姿勢にて入力側接続部が支持フレーム部に設けた出力側接続部に接続される一方、一側可動側施肥部の排出姿勢にて入力側接続部が出力側接続部から切断されるようにしているため、一側可動側施肥部の姿勢を変更させるに際して、入力側接続部と出力側接続部との接続・切断操作を逐一行う必要性がない。そのため、作業者が入力側接続部と出力側接続部との接続・切断操作をし忘れるという不具合がなくなり、操作性が向上する。
また、かかる施肥装置は、乗用田植機の走行装置に設けた座席の背後に左右方向に横長状に載設することで、各排出部を施肥装置の左右側端部に配置することができるため、オペレータは走行装置に搭乗して両可動側施肥部を略水直に跳ね上げた排出姿勢となすことで、各排出部を通して排出作業を楽に行うことができる。この際、走行装置の左右外側方位置で下方へ指向した各排出部の直下方位置に回収容器を配置しておけば、同回収容器内に流下状態に排出される残留肥料を楽に回収することができる。また、排出ホースを繰り出し部に接続することなく排出作業を行うことができるため、従来のように各繰り出し部に接続した排出ホースの煩雑な取り回しに苦慮する必要性がない。
そして、分離・接合自在とした前記下部側繰り出し体の上端開口縁部と前記上部側繰り出し体の下端開口縁部との間には、シール材を介設しているため、各可動側施肥部の繰り出し姿勢と排出姿勢との姿勢変更時に、分離と接合を繰り返す上・下部側繰り出し体の上・下開口縁部同士を保護することができると共に、密閉性を良好に確保することができる。
また、かかる施肥装置は、乗用田植機の走行装置に設けた座席の背後に左右方向に横長状に載設することで、各排出部を施肥装置の左右側端部に配置することができるため、オペレータは走行装置に搭乗して両可動側施肥部を略水直に跳ね上げた排出姿勢となすことで、各排出部を通して排出作業を楽に行うことができる。この際、走行装置の左右外側方位置で下方へ指向した各排出部の直下方位置に回収容器を配置しておけば、同回収容器内に流下状態に排出される残留肥料を楽に回収することができる。また、排出ホースを設けることなく排出作業を行うことができるため、従来のように各繰り出し部に接続した排出ホースの煩雑な取り回しに苦慮する必要性がない。
この際、受け体の受け面側には、同芯短幅筒状の内・外側密着片を半径方向に間隔を開けて撓み変形自在に突設しているため、受け体が開口縁部を受けた際には内・外側密着片が撓み変形されて、密着性が良好に確保される。
そして、各可動側施肥部の内側端部に垂設した各支持脚体の下端部は、前記繰り出し姿勢で前記支持フレーム部に係合させることで、各可動側施肥部を位置決めするようにしているため、各可動側施肥部を繰り出し姿勢に堅実に位置決めすることができる。そのため、位置決めされた繰り出し姿勢から排出姿勢への姿勢変更も円滑に行うことができて、排出作業を効率良く行うことができる。
また、かかる施肥装置は、乗用田植機の走行装置に設けた座席の背後に左右方向に横長状に載設することで、各排出部を施肥装置の左右側端部に配置することができるため、オペレータは走行装置に搭乗して両可動側施肥部を略水直に跳ね上げた排出姿勢となすことで、各排出部を通して排出作業を楽に行うことができる。この際、走行装置の左右外側方位置で下方へ指向した各排出部の直下方位置に回収容器を配置しておけば、同回収容器内に流下状態に排出される残留肥料を楽に回収することができる。また、排出ホースを設けることなく排出作業を行うことができるため、従来のように各繰り出し部に接続した排出ホースの煩雑な取り回しに苦慮する必要性がない。
そして、各前記可動側施肥部は、各前記枢支・連結部を中心に繰り出し姿勢から排出姿勢まで回動する回動角度を鈍角となして、排出姿勢では各前記可動側施肥部の重心位置が前記枢支・連結部よりも外方に位置するようにしているため、各前記可動側施肥部は略垂直に跳ね上げた起立状態の排出姿勢で安定に保持される。そのため、かかる排出姿勢にて各前記可動側施肥部を固定する手段を設ける必要性がなく、また、固定状態を解除して繰り出し姿勢に姿勢変更する手間も生じない。従って、排出部から残留肥料を排出する作業を効率良く行うことができる。
また、かかる施肥装置は、乗用田植機の走行装置に設けた座席の背後に左右方向に横長状に載設することで、各排出部を施肥装置の左右側端部に配置することができるため、オペレータは走行装置に搭乗して両可動側施肥部を略水直に跳ね上げた排出姿勢となすことで、各排出部を通して排出作業を楽に行うことができる。この際、走行装置の左右外側方位置で下方へ指向した各排出部の直下方位置に回収容器を配置しておけば、同回収容器内に流下状態に排出される残留肥料を楽に回収することができる。また、排出ホースを設けることなく排出作業を行うことができるため、従来のように各繰り出し部に接続した排出ホースの煩雑な取り回しに苦慮する必要性がない。
また、繰り出し姿勢では、各前記可動側施肥部の内側端部にそれぞれ垂設した支持脚体を前記支持フレーム部に係合させることで、同支持フレーム部と前記回動支持アームと前記可動側施肥部と上記支持脚体とで枠状位置決め体を形成することができる。そして、かかる枠状位置決め体を形成することで、一側可動側施肥部と他側可動側施肥部をそれぞれ排出姿勢から繰り出し姿勢に姿勢変更する際に、簡単かつ確実に位置決めすることができる。また、施肥装置をフレーム構造にしてその剛性を良好に確保することができる。ここで、ホッパー部は軽量かつ硬質材料で成形することで、同ホッパー部を強度メンバーとして機能させることができると共に、各可動側施肥部を軽量化して、各可動側施肥部の姿勢変更作業を楽に行うことができる。
かかる施肥装置は、乗用田植機の走行装置に設けた座席の背後に左右方向に横長状に載設することで、各排出部を施肥装置の左右側端部に配置することができるため、オペレータは走行装置に搭乗して両可動側施肥部を略水直に跳ね上げた排出姿勢となすことで、各排出部を通して排出作業を楽に行うことができる。この際、走行装置の左右外側方位置で下方へ指向した各排出部の直下方位置に回収容器を配置しておけば、同回収容器内に流下状態に排出される残留肥料を楽に回収することができる。また、排出ホースを設けることなく排出作業を行うことができるため、従来のように各繰り出し部に接続した排出ホースの煩雑な取り回しに苦慮する必要性がない。
この際、前記一側可動側施肥部を枢支・連結した前記支持フレーム部の一側端部には、前記下部側繰り出し体に肥料圧送風を供給する圧送風供給部を設けている。しかしながら、圧送風供給部は、圧送風を供給可能な圧送風供給姿勢と、圧送風を供給不能な圧送風不供給姿勢とに姿勢変更自在とし、しかも、圧送風不供給姿勢では前記一側可動側施肥部の繰り出し姿勢と排出姿勢との姿勢変更動作面外である不干渉位置に位置する干渉回避姿勢を採ることができるようにしている。そのため、一側可動側施肥部を排出姿勢に姿勢変更する際には、あらかじめ圧送風供給部を干渉回避姿勢に姿勢変更することで、一側可動側施肥部を圧送風供給部と干渉させることなく排出姿勢に姿勢変更することができる。従って、前記支持フレーム部の一側端部に枢支・連結した一側可動側施肥部であっても、排出部の下方への指向性を良好に確保することができて、同排出部からの堅実な排出性を確保することができる。また、干渉回避姿勢の圧送風供給部は、圧送風不供給姿勢でもあるため、残留肥料の排出作業時に誤動作で圧送風が供給されることがない。
また、かかる施肥装置は、乗用田植機の走行装置に設けた座席の背後に左右方向に横長状に載設することで、各排出部を施肥装置の左右側端部に配置することができるため、オペレータは走行装置に搭乗して両可動側施肥部を略水直に跳ね上げた排出姿勢となすことで、各排出部を通して排出作業を楽に行うことができる。この際、走行装置の左右外側方位置で下方へ指向した各排出部の直下方位置に回収容器を配置しておけば、同回収容器内に流下状態に排出される残留肥料を楽に回収することができる。また、排出ホースを設けることなく排出作業を行うことができるため、従来のように各繰り出し部に接続した排出ホースの煩雑な取り回しに苦慮する必要性がない。
