Work device for work vehicle

Abstract

(57)【要約】 【課題】 草刈り装置などの作業装置を自立状態で容易 に移送する。 【解決手段】 作業車両であるトラクタ1に着脱される ブーム9の前端部に上リンク機構10を前後回動自在に 支持し、その上リンク機構10に下リンク機構(アーム) 11を前後回動自在に支持し、その下リンク機構11に 草刈り機12を回動可能に支持する。その草刈り機12 を地面Gに接地させるとともに上記ブーム9及び下リン ク機構11を下向きに折り畳んだ収納姿勢Aでは、草刈 り装置2の重心Wを上記の草刈り機12の前後の車輪2 1・22の間に位置させる。その収納姿勢Aで、上記ブ ーム9の基部に設けた枢支ピン8と上記の草刈り機12 の後部に設けたブラケット38とを連結具Dによって連 結する。その連結具Dは、ネジ筒30を軸心回りに旋回 させることによって長手方向へ伸縮される。
PROBLEM TO BE SOLVED: To easily transfer a work device such as a mowing device or the like in a self-standing state. SOLUTION: An upper linking mechanism 10 is supported freely turnably back and forth to the front end part of a boom 9 attached and detached to/from a tractor 1 which is a work vehicle, a lower linking mechanism (arm) 11 is supported to the upper linking mechanism 10 freely turnably back and forth and a mower 12 is turnably supported to the lower linking mechanism 11. In a housing attitude A for which the mower 12 is grounded to a ground surface G and the boom 9 and the lower linking mechanism 11 are folded downwards, the centroid W of the mower 2 is positioned between the front and rear wheels 21 and 22 of the mower 12. In the housing attitude A, a pivotally supporting pin 8 provided on the base part of the boom 9 and a bracket 38 provided on the rear part of the mower 12 are connected by a connector D. The connector D is extended and compressed in a longitudinal direction by rotating a screw cylinder 30 around an axis. COPYRIGHT: (C)1998,JPO
