The invention relates to engineering machinery, in particular to a screening bucket of an excavator. The bucket can be automatically installed through cooperative work of oil cylinders, primary screening can be carried out through a screening bucket assembly, secondary screening can be carried out through the excavator bucket, and tertiary screening can be carried out through an adjustable screening plate assembly. When the bucket is installed, a first arc hook hooks a pin shaft on the bucket, the second arc hook hooks the pin shaft on the bucket, and installation is automatically completed. During use, screening holes in the screening bucket play a role in primary screening, a motor drives a crankshaft to move, and the radial movement of a crankshaft connecting rod is converted into the reciprocating movement of the screening bucket around a sixth rotating shaft in a bucket body; the bucket body plays a role in secondary screening, and water is sprayed outwards from a spray head to achieve the effects of cleaning and dust removal; and the motor drives a one-way clutch and a sleeve to only rotate in one direction, so that all connecting rods of the screening plate assembly can be straightened, screening plates are fixed to all the connecting rods, and every two adjacent screening plates play a role in tertiary screening.
本发明涉及一种工程机械，更具体的说是一种挖掘机筛分斗。可以通过油缸的协同工作自动安装铲斗，可以通过筛分斗组合体进行第一次筛分，可以通过挖机铲斗进行第二次筛分，可以通过可调筛分板组合体进行第三次筛分。安装铲斗时，使圆弧钩一钩住铲斗上的销轴，使圆弧钩二钩住铲斗上的销轴自动完成安装；使用时，筛分斗上的筛分孔起到一次筛分作用，电机带动曲轴运动，将曲轴连杆在径向的运动转化为筛分斗绕着转轴六在铲斗体内的往复运动；铲斗体起到二次筛分作用，并从喷头处向外喷水达到清洗并除尘的作用；电机带动单向离合器和套筒仅做单向旋转，即可调筛分板组合体的各连杆均被拉直，各连杆上固定筛分板，相邻两个筛分板起到三次筛分作用。
