The invention provides a screw adjustment mechanism. The screw adjustment mechanism is applied to an orange-peel bucket, and comprises an axial limiting sleeve, a rotation driving assembly and a plurality of rotation adjustment blocks. The orange-peel bucket is further provided. The orange-peel bucket comprises the screw adjustment mechanism, a central column and a plurality of sets of mobile grabbing and closing mechanisms, each set of mobile grabbing and closing mechanism comprises a mobile supporting assembly, mobile grabhooks are rotatably connected with the mobile supporting assemblies, first telescopic driving assemblies are arranged on the mobile supporting assemblies, and rotation adjustment blocks are connected with the mobile supporting assemblies. The crane is further provided.The crane comprises the orange-peel bucket and a mechanical arm, and the mechanical arm is connected with the central column. The mobile supporting assemblies are driven by the screw adjustment mechanism to slip in a circumferential direction of the central column, the mobile grabhooks and the first telescopic driving assemblies which are arranged on the mobile supporting assemblies move along with the mobile supporting assemblies, relative position relations between the mobile grabhooks change, that is to say, grabbing points of the mobile grabhooks can be adjusted, so that the orange-peel bucket is suitable for grabbing waste in conventional shapes and waste in special shapes.

    本发明提供一种螺旋调节机构,应用于多瓣抓斗,包括轴向限位套筒、旋转驱动组件和若干旋转调节块。本发明还提供一种多瓣抓斗,包括上述螺旋调节机构、中心柱体和若干组动抓合机构,每组动抓合机构均包括动支撑组件,动支撑组件上转动连接有动抓爪,动支撑组件上还设有第一伸缩驱动组件,旋转调节块与动支撑组件相连。本发明还提供一种起重机,包括上述多瓣抓斗和机械臂,机械臂与中心柱体相连。通过螺旋调节机构驱使动支撑组件沿中心柱体的周向滑移,设置在动支撑组件上的动抓爪和第一伸缩驱动组件也随之移动,各动抓爪之间的相对位置关系发生变化,即动抓爪的抓取点可以调节,从而适用于常规形态废料和特殊形态废料的抓取。
