Abstract

Nóż urabiający skonfigurowany do połączenia z bębnem, który może obracać się wokół osi  Nóż urabiający zawiera trzon skonfigurowany do połączenia z uchwytem noża bębna. Nóż urabiający zawiera również głowicę połączoną z trzonem. Głowica (34) zawiera krawędź przednią, krawędź tylną oraz część podcięciową. Część podcięciowa jest skonfigurowana do przyjmowania narzędzia do usuwania w celu usunięcia noża urabiającego z uchwytu noża, gdy głowica (34) jest połączona z trzonem. Część podcięciowa jest skonfigurowana również do wywołania uszkodzenia głowicy, w którym to przypadku co najmniej część głowicy może się złamać i oddzielić od trzonu podczas pracy noża urabiającego.
