FRONT LOADER AND WORK MACHINE
To provide a front loader which has a mechanism of holding the attitude of a bucket, and prevents the mechanism from affecting a front field of view of a worker operating the front loader.SOLUTION: A front loader includes a boom, a bucket which is supported so as to enable a scooping-dumping operation around a first pivot provided on the tip side of the boom, a boom cylinder which swings the boom, a bucket cylinder which scoops and dumps the bucket, a control valve which can switch between a first state of supplying hydraulic oil to the bucket cylinder and a second state of stopping supply of the hydraulic oil to the bucket cylinder, a first movable member capable of rotating around the first pivot along the operation of the bucket, and a wire connecting the first movable member and the control valve.SELECTED DRAWING: Figure 1
【課題】バケットの姿勢を保持する機構を備えつつ、当該機構がフロントローダを操作する作業者の前方の視界に影響を及ぼしにくいフロントローダを提供すること。【解決手段】フロントローダは、ブームと、ブームの先端側に設けられた第１枢軸回りにスクイ及びダンプ動作可能に支持されたバケットと、ブームを揺動させるブームシリンダと、バケットをスクイ及びダンプ動作させるバケットシリンダと、バケットシリンダに作動油を供給する第１状態とバケットシリンダへの作動油の供給を停止する第２状態とに切り換え可能な制御バルブと、バケットの動作に伴って第１枢軸回りに回動可能な第１可動部材と、第１可動部材と制御バルブとを接続するワイヤと、を備えている。【選択図】図１
