Technical Field

[0001] The utility model relates to the technical field of impact crushers, and particularly to a belt pulley protection device for an impact crusher. Background Technique

[0002] The impact crusher, also known as the impact breaker, is mainly used for the processing of materials that often need to be relocated in metallurgy, chemical industry, building materials, hydropower, etc., especially for the operation of mobile stone materials in expressways, railways, hydropower projects, etc. It can adopt various configuration forms according to different types, scales of processed raw materials and requirements of finished materials. When the impact crusher is in use, the belt pulley needs to be protected to prevent damage to the device during use.

[0003] After retrieving the Chinese patent "A Belt Pulley Protection Device", the publication number is "CN217736228U". This patent sets an active connecting rod. When it is necessary to protect belt pulleys of different sizes, the fixing bolts can be loosened, and then the active connecting rod can be slid. In this way, the distance between the first sliding rod and the second sliding rod can be adjusted, so as to be applicable to belt pulleys of different sizes. Users can freely adjust according to the size of the belt pulley, greatly reducing the limitation of the whole device, effectively increasing the compatibility of the whole device, and making it more convenient to use. However, the protection effect of this device on the belt pulley is poor, and it is not convenient to effectively protect the belt pulley when there is a deviation between the belt pulley and the belt, reducing the use effect of the device.

[0004] Therefore, a belt pulley protection device for an impact crusher is proposed to solve the above problems. Content of the Utility Model
