In chute；
Sound level meter, its horizontal component for being fixed on first travelling carriage, the surface of shell of the sound level meter opens up multiple
Thermovent, radiating discharge surface covering ventilated membrane；
Sound arrester, it includes multiple the second travelling carriages in inverted U-shaped structure parallel to each other, is fixed on multiple second and slides
The first puigging at the top of moving frame, and it is separately fixed at two the two of the horizontal component of the second travelling carriage pieces positioned at two ends
Two puiggings, second puigging is sized to cover the blank position of second travelling carriage, described first every
Sound-absorbing layer is respectively provided with the buckle and snap ring worked in coordination with the vertical both sides of second travelling carriage；Wherein, each described second
Slide respectively and be located in two external chutes in two lower ends of travelling carriage.
More excellent, described noise-measuring instrument, first puigging includes being separated by one with second puigging
The two-layer deadening fabric of set a distance and one central space of formation, the central space is separated into multiple independent subspaces, each
Sound insulation by filling cotton in subspace.
More excellent, described noise-measuring instrument, the ventilative film thickness is 3mm.
More excellent, described noise-measuring instrument, first travelling carriage is coated with the lower end of second travelling carriage
Wear-resistant material layer.
The height of more excellent, described noise-measuring instrument, first travelling carriage and second travelling carriage is above
The height of stock-removing machine.
Compared with prior art, the beneficial effects of the utility model are：Sound arrester is set, can effectively just extraneous ring
The noise isolation in border, efficiently measures the noise situation of stock-removing machine itself；And sound level meter is fixed on the first travelling carriage, the
One travelling carriage is slided along two internal chutes, the measurement in space to stock-removing machine noise can be so realized, without being integrally fixed at
One place is motionless, causes measurement result not prepare.
