Description

Technical Field

[0001] The utility model belongs to the technical field related to shredders, and specifically relates to a shredder blade installation structure. Background Art

[0002] A shredder is a machine used for coarse crushing, generally used to process unprocessed raw materials or scraps, and to recycle and regenerate them to make them smaller in size. Compared with other crushers, the shredder has a low blade shaft speed, low noise, and low energy consumption. Patent No.: CN200920262543.5 discloses a shredder blade roller structure, which adopts a structure in which a blade holder and a cutter disc are connected by a fastening screw, which changes the welding structure of the traditional blade holder and the cutter disc, making it more convenient to replace the blade holder. However, the power seat is fixedly installed in the seat groove of the cutter disc by a fastening screw, and the moving knife is fixedly installed on the power seat by a fastening screw. When the moving knife is fixedly installed, the tightening direction of the fastening screw is the tangential direction of the circumference of the cutter disc body. When the tightening of the fastening screw is adjusted, interference will occur between the wrench and the cutter disc body, and the full circle operation cannot be performed, resulting in inconvenient operation when replacing the blade holder or blade. The moving knife and the cutter disc are fixedly installed by a single fastening screw. The blade is easy to loosen during the operation of the shredder, affecting the service life of the blade.

[0003] In view of this, the present utility model is proposed. Utility Model Content
