２０１４７５号）。2. Description of the Related Art Conventionally, a crusher for crushing waste such as plastic molded products and metal cans has a drive shaft with a coarse crushing blade and a fine crushing blade fixed in a skewered manner. It is known that a fixed comb blade is provided so as to face the crushing blade to crush a plastic molded product or the like (see Japanese Utility Model Laid-Open No. 61-3461). Further, a large shred cutter and a small crushing cutter are fixed in a skewered manner on two driving shafts that are supported in parallel with each other, and are provided between the small crushing cutters that are opposed by the two driving shafts. It is known to have a fixed blade that rotates two drive shafts in opposite directions. (US Patent 5
2014475).

被破砕物の食い込みができなくなり、破砕能力がなくな
るため頻繁に固定櫛刃周辺の手入れが必要であった。In the former of those described in the prior art, since the coarse crushing blade and the fine crushing blade provided on the drive shaft are opposed to one fixed comb blade, the object to be crushed is crushed. When crushing, the object to be crushed flies by equilibrium force between the rough crushing blade and the fixed comb blade, or between the fine crushing blade and the fixed comb blade and dances in the machine frame. Furthermore, the peripheral speed of the fine crushing blade is smaller than that of the coarse crushing blade, so the crushing ability is greatly reduced, and the crushed object sticks to the fixed comb blade until there is no gap between the crushing blade and the outer diameter of the fine crushing blade Then, it becomes impossible to bite the crushed object between the coarse crushing blade and the fixed comb blade and between the fine crushing blade and the fixed comb blade, and the crushing ability is lost, so that frequent maintenance of the periphery of the fixed comb blade is required.
