Data crushing device

The utility model relates to the technical field of data crushing, in particular to a data crushing device which can circularly crush data with plastic outer packages. Comprising a screw motor, a conveying screw, a maintenance box and a conveying pipeline, if data with plastic packaging skins cannot be crushed at a time, large chippings can slide to a circulation opening from an inclined sieve plate, the data is crushed in the next stage through the circulation opening, large chippings are automatically collected in the maintenance box, and the crushing efficiency is improved. And the conveying screw rod rotates to convey large chippings in the maintenance box into the box body through the conveying pipeline for continuous mincing. 本实用新型涉及资料粉碎技术领域，更具体的说是一种资料粉碎装置，能对带有塑料外包装的资料进行循环粉碎。包括螺杆电机、传送螺杆、维修箱和传送管道，若带有塑料包装皮的资料不能进行一次进行粉碎，大的碎屑块会从斜筛板上滑落至循环口，通过循环口对资料进行下一阶段的粉碎，大块碎屑自动收集在维修箱内，传送螺杆转动将维修箱内的大块碎屑通过传送管道传送至箱体内继续进行绞碎。
