The invention relates to the technical field of grabbing tools, in particular to a rotary cutting type grab bucket device. The cargo grabbing range of a grab bucket can be adjusted. The rotary cuttingtype grab bucket device comprises a diameter expansion adjusting mechanism, a plurality of combined grab bucket mechanisms, a rotary cutoff mechanism, a rotation driving mechanism, a horizontal balancing mechanism and a follow-up covering protective mechanism. An expansion motor drives a driving bevel gear to rotate. The driving bevel gear drives a plurality of follow-up bevel gears to rotate. The plurality of follow-up bevel gears drive a plurality of rotating lead screws to rotate to enable the plurality of combined grab bucket mechanisms to move, so that the grabbing range and capacity ofthe plurality of combined grab bucket mechanisms are changed and adjusted correspondingly according to the grabbing capacity required each time. The rotary cuttoff mechanism drives the diameter expansion adjusting mechanism and the plurality of combined grab bucket mechanisms to rotate together, so that the adhesion parts of cargos to the plurality of combined grab bucket mechanisms are cut off ina rotated mode. The risk that the adhesion parts of the cargos are not located in the plurality of combined grab bucket mechanisms and fall off is avoided.

    本发明涉及抓取工具技术领域,更具体的说是一种旋切式抓斗装置。可以调节抓斗抓取货物的抓取范围。包括直径阔张调节机构、组合式抓斗机构、旋转割断机构、旋转驱动机构、水平平衡机构和随动遮盖防护机构,阔张电机带动主动锥齿轮转动,主动锥齿轮带动多个随动锥形齿轮转动,多个随动锥形齿轮分别带动多个转动丝杆转动使多个组合式抓斗机构进行移动,为多个组合式抓斗机构改变抓取范围以及容量,实现根据需要单次抓取的需求量进行相应的调节,旋转割断机构带动直径阔张调节机构和多个组合式抓斗机构一同转动,将货物与多个组合式抓斗机构外界的粘连处被旋转断开,避免了货物上的粘连物因为没有位于多个组合式抓斗机构内从而出现掉落的危险。
