CLAMSHELL BUCKET
To provide a clamshell bucket that ensures an earth removal property and sufficient strength and in which an increase in weight is restricted.SOLUTION: A pair of buckets 19, 24 of a clamshell bucket 11 are composed of: bottom plates 20, 25, the front end sides of which are sediment outflow/inflow openings 20A, 25A to receive sediments flowing inside in the closed position; a pair of side plates 21, 26 that are provided on both the widthwise ends of the bottom plates 20, 25 respectively and that face each other; and sediment storage spaces S1, S2 that are formed in an inner space surrounded by the bottom plates 20, 25 and the pair of side plates 21, 26. The bottom plates 20, 25 of the buckets 19, 24 are composed of: curved parts 20B, 25B extending from the sediment outflow/inflow openings 20A, 25A in a convex manner; and bent parts 20C, 25C that are provided on the rear end sides of the curved parts 20B, 25B located on the opposite side to the sediment outflow/inflow openings 20A, 25A and that bend toward a direction away from a rotation fulcrum O.SELECTED DRAWING: Figure 2
【課題】排土性と十分な強度を確保しつつ、重量の増加を抑制させたクラムシェルバケットを提供する。【解決手段】クラムシェルバケット１１の一対のバケット１９，２４は、前端側が土砂の流出入開口２０Ａ，２５Ａとなり閉位置で内部に流入した土砂を受ける底板２０，２５と、底板２０，２５の幅方向の両端部にそれぞれ設けられ互いに対面する一対の側板２１，２６と、底板２０，２５と一対の側板２１，２６とにより囲まれた内部に形成された土砂溜め空間Ｓ１，Ｓ２とからなっている。バケット１９，２４の底板２０，２５は、流出入開口２０Ａ，２５Ａから凸状に湾曲して延びる湾曲部２０Ｂ，２５Ｂと、流出入開口２０Ａ，２５Ａとは反対側に位置する湾曲部２０Ｂ，２５Ｂの後端側に設けられ回動支点Ｏから離れた方向に向けて屈曲した屈曲部２０Ｃ，２５Ｃとからなっている。【選択図】図２
