And this application sets up to spine structure through with first skid resistant course and second skid resistant course, and the cross-sectional area of each serrated knife 321 is by being close to the one end of decomposing gyro wheel 320 to keeping away from the one end of decomposing gyro wheel 320 and crescent, make to handle the reclaimed materials by spacing while, each serrated knife 321 is bigger to the cutting scope of handling the reclaimed materials, thereby make the dispersion effect of handling the reclaimed materials better, and when cutting the reclaimed materials of handling, difficult rupture, effectively increased the practicality of decomposer 300.
Furthermore, the disassembling machine 300 further includes a plurality of sleeves, each of the sleeves is provided with a through hole, and one end of each of the serrated knives 321 close to the disassembling roller 320 is respectively inserted into the through hole. Specifically, the one end of lantern ring is connected with decomposition gyro wheel 320, overlaps respectively through the one end that is close to decomposition gyro wheel 320 with each serrated knife 321 and is equipped with the lantern ring for each serrated knife 321's installation is more firm, and each serrated knife 321 is inseparabler with the being connected of decomposition gyro wheel 320 promptly, and each serrated knife 321 can receive the protection of lantern ring when using, effectively prolongs the life of each serrated knife 321.
