[0001] The utility model relates to a blockage clearing device, in particular to a device capable of clearing blocked materials in a silo, belonging to the technical field of silo blockage clearing equipment. Background Art

[0002] Silo is an important equipment for storing materials. Raw materials are fed to the transmission mechanism under the silo and then transported to various designated locations. Since the materials have a certain amount of moisture and adhesion, it is very easy to cause silo bulging and silo sticking during the unloading process, resulting in the material being unable to fall and be discharged smoothly. For the situation of material blockage in the silo, it is generally dredged by manually knocking on the outer wall of the silo or by blowing high-pressure air. This method is inefficient and not comprehensive. Therefore, a dredging device is needed, which is required to be able to comprehensively and efficiently dredge the silo blockage to ensure the smooth unloading of the silo. Utility Model Content
