<P>PROBLEM TO BE SOLVED: To provide a waste straw shredder capable of effectively preventing entwining or clogging with dust in a bearing or a rotation shaft. <P>SOLUTION: The waste straw shredder includes: a case-side cover 53 fixed to the inner side of a shredding case 40 in such a state as located coaxially with the rotation shaft 42 on the outer periphery of a holder 50 of the bearing 51; and a shaft-side cover 54 which is integrally rotatably connected to the rotation shaft 42 in such a state that the outer peripheral part 54c overlaps with the case-side cover 53 in the radial direction of the rotation shaft 42, and which relatively rotates to the case-side cover 53. A dust discharge opening 55 is disposed below the case-side cover 53 for discharging dust from a cover inner space 56 formed in the periphery of the holder 50 by the case-side cover 53 and the shaft-side cover 54. A rotary member 57 for scraping off the dust to the dust discharge opening 55 is disposed in the cover inner space 56 in such a state as rotatable integrally with the rotation shaft 42. <P>COPYRIGHT: (C)2013,JPO&INPIT |
