Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine blade cutting, in particular to a cutting device for recycling discarded wind turbine blades. Background Art

[0002] Most wind turbine blades are over 40m long and over 2m wide. They are large in size and are mostly made of thermosetting and fiber materials. They cannot be naturally degraded, and discarded blades need to be disposed of harmlessly. As the early wind turbine blades are approaching the end of their service life, many wind power plants now need to clean up retired and scrapped blades. Due to the extremely high cost of transporting and transferring the entire blade, it is generally chosen to dismember it on site before subsequent processing; however, due to the large size of wind turbine blades and the harsh on-site environment, they are cut into small pieces by traditional manual cutting methods, so that they can be crushed and reused.
