[0059] Specifically, when the fan 4 blows the waste chips on the machining center body 1 and the moving component 2 through the output pipe 5, the three-way joint, the connecting rod 6, the U-shaped tube 7 and the air collecting hood, the waste chips can be blocked by the blocking shell 82, so that the waste chips can fall into the collecting box 81 for collection, thereby facilitating the later recycling and reprocessing of the waste chips, which can effectively save natural resources.
