This utility model discloses an anti-clogging device for the blower pipe of a wind-powered coal preparation machine, relating to the technical field of wind-powered coal preparation machines. It includes a protective cover, with a wind classifier fixedly connected to the inner side of the cover. A blower is fixedly connected to one side of the wind classifier, and the blowers are arranged sequentially from front to back. An air duct is provided inside the protective cover, and the air duct is connected to the blower. A mounting frame is fixedly connected to the inner side of the air duct, and a rotating rod is rotatably connected to the inner side of the mounting frame. Connecting frames are fixedly connected to both sides of the outer side of the rotating rod. This anti-clogging device for the blower pipe of the wind-powered coal preparation machine has a reasonable structural design. It can filter and crush large coal particles, preventing them from clogging the collection pipe. It can also clean coal dust accumulated inside the blower pipe, preventing coal dust from accumulating and causing blockage.
