【発明の属する技術分野】
本発明は例えば苗載台及び植付爪を備えて連続的に苗植作業を行う田植機にあって、苗載台など植付部の左右全幅を縮小させるようにした田植機の植付装置に関する。
【0002】
【発明が解決しようとする課題】
例えば10条など多条用田植機にあって、苗載台とともに植付ケース及びフロートなど植付部の左右外側の2条分など複数条分を略90度上方に回動させ機体内側に折畳みする手段があるが、この場合折畳んだ左右外側のフロート間巾が最大巾となり、植付部の左右全幅が余り縮小されず、略6条巾とするためにはフロートを取外す必要がある。また折畳みされた植付ケースや植付ケースの伝動パイプと、本体固定側の苗載台の左右端部とが干渉するため、干渉を回避させるためには全幅が広くなる不都合がある。
【0003】
【課題を解決するための手段】
請求項1に係る発明は、機体中央の苗載台本体の左右両側に分割苗載台を連結して、前記分割苗載台を、中央固定側の苗載台本体の上方に折畳み機構を介して略平行に折畳むように構成してなる田植機の植付装置において、植付爪を配置してこれを駆動するための植付ケースを、中央固定側の植付ケースと分割側植付ケースとに分割し、前記各植付ケース間を連結しかつ植付伝動軸を内設するための伝動パイプを、固定側パイプと分割側パイプとに分割して、前記固定側パイプと分割側パイプとの分割部をロック機構にて連結し、前記中央固定側の各植付ケースの後端間をブラケットを介して支点フレームにて連結し、前記分割側植付ケースの後端にブラケットを介して回動フレームを連結し、前記支点フレーム及び回動フレームは、前記各植付ケースの後端より後方にて横長に配置し、前記支点フレームの両端部に各回動フレームの一端部を折畳み支点軸にて連結し前記分割側植付ケースを前記中央固定側の植付ケースに対して略垂直で、かつ前記分割側植付ケースを前記中央固定側の植付ケース後端より後方に折畳み収納するように構成し、前記分割側植付ケースを折畳み位置にロックするためのロック部材を備え、前記ロック部材の基端側を、前記支点フレームの取付台に枢軸を介して回動可能に連結させ、前記ロック部材の先端側と前記分割側植付ケースとを着脱可能に連結するためのロック体を前記分割側植付ケースの前側に設置し、折畳まれた前記分割側植付ケースを、前記中央固定側の植付ケースに前記ロック部材及びロック体を介して連結するように構成したものであるから、分割された苗載台の後方に植付ケース及びフロートなどを干渉させることなく重なる状態に良好に折畳んで、植付部の左右全幅を規定巾内に縮小できる。

Are connected by a lock mechanism, the rear ends of the planting cases on the center fixed side are connected by a fulcrum frame via brackets, and brackets are connected to the rear ends of the split side planting cases. The pivot frame, and the fulcrum frame and the pivot frame are The rear case is arranged horizontally behind the rear end, and one end of each rotating frame is connected to both ends of the fulcrum frame by folding fulcrum shafts, and the split-side planting case is attached to the center fixed side planting case The split side planting case is configured to be folded and stored behind the rear end of the center fixed side planting case, and the split side planting case is locked in the folded position. A lock member is provided, and a base end side of the lock member is rotatably connected to a mounting base of the fulcrum frame via a pivot so that the distal end side of the lock member and the split-side planting case can be attached and detached. A lock body for connection is installed on the front side of the split-side planting case, and the folded split-side planting case is connected to the center-fixing-side planting case via the lock member and the lock body. What was configured to Some because, in good folded state overlapped without causing interference, such as planting case and float divided seedling placing stand behind, can be reduced right entire width of the planting unit within the specified width.
