[0001] The utility model relates to the technical field of crusher protection, and more specifically to a split cutter shaft protective cover. Background Art
[0002] In the process of recycling construction materials, due to the large volume of recycled construction material raw materials, they are usually pre-crushed first, and then handed over to the crushing device for further crushing processing. The recycling of construction materials can greatly reduce production costs. Not only that, it can also reduce the pollution of construction waste and meet the green construction standards.
[0003] During the processing of the crusher, a protective cover needs to be installed on the damaged blade to protect the operator. However, the existing crusher blade shaft has an integrated protective cover, and the entire cover needs to be removed. The blade can only be maintained and replaced after the cover is lifted away, which is very inconvenient during the blade maintenance and replacement process. The utility model proposes a new solution to the above problem. Utility Model Content
