<p><P>PROBLEM TO BE SOLVED: To provide a wood branch/leaf crushing machine capable of definitely reducing a crushing sound that leaks outside. <P>SOLUTION: In the wood branch/leaf crushing machine, a shooter 60 that discharges crushed pieces is provided at a crushing machine body 5 that crushes injected wood branch/leaves, and an acoustic material 63 is affixed to an internal surface of the shooter 60. Therefore, even if a pileup spot enough to be able to provide an acoustic mechanism can not be secured in an injection hopper or the like, providing the shooter 60 with the material 63 allows the crushing sound that leaks from an opening 62 for discharge of the shooter 60 to be definitely reduced, thereby realizing the reduction of noise. In addition, the reduction of the noise can be further promoted by shielding the inside of the shooter 60 with a sheet-like member 64 of sound absorption performance. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
