    • PURPOSE:To smoothly discharge soil and to improve excavation efficiency, by a method wherein a bucket shell is openably mounted to a bucket body, a hydraulic cylinder is provided, and a blade is vertically movably attached to a piston rod. CONSTITUTION:A blade 18 is separated from upper plates 16a and 17a of bucket shells 16 and 17 with the aid of a hydraulic cylinder 20, and the bucket shells are held in an opening attitude. The bucket shells 16 and 17 are pushed in, soil is scooped in the shells 16 and 17, and the shells 16 and 17 are closed through contraction of the hydraulic cylinder 20. The bucket shells are lifted up to a ground, the blade 18 is lowered within the shells 16 and 17 through expansion of the cylinder 20 to discharge soil. This enables smooth discharge of soil by means of the blade irrespective of quality of soil excavated by the bucket shells.
    • 目的:为了平稳地排放土壤并提高挖掘效率,通过将铲斗壳体可开启地安装在铲斗本体上的方法,设置液压缸,并且将叶片垂直地可移动地附接到活塞杆。 构成:叶片18借助于液压缸20与桶壳16和17的上板16a和17a分离,并且桶壳保持打开姿态。 铲斗壳体16和17被推入,铲斗16和17中挖出土壤,并且通过液压缸20的收缩使壳体16和17关闭。铲斗壳体被提升到地面,叶片18是 通过气缸20的膨胀而在壳16和17内降低以排出土壤。 这样就可以通过叶片平稳排放土壤,而不管桶壳挖出的土壤质量如何。
