Abstract
The utility model provides a silence backstroke crusher, including the casing, be equipped with center pin and counterattack board in the casing, be provided with the disc on the center pin, be provided with the tup on the disc, still be equipped with the feed inlet on the casing, be equipped with the pivot on the feed inlet, be equipped with in the pivot and seal the board, still be equipped with the reflection sound absorbing layer on sealing the surface of board and casing, the sound hole of inhaling that continuous layer upper surface of sound and lower surface all were equipped with the indent is inhaled including inhaling continuous layer of sound and reflection stratum to the reflection sound absorbing layer. The utility model discloses a be equipped with on the feed inlet and seal the board, can move round the pivot, can completely cut off the noise that spreads to a certain extent in the casing, and still be equipped with the reflection sound absorbing layer on sealing board and casing, inhaling the continuous layer of sound and can absorb the noise that spreads out of in the casing on the reflection sound absorbing layer, the surplus does not have absorptive noise, passes and inhales the continuous layer back of sound, is reflected by the reflection stratum again, is inhaled the continuous layer of sound once more and absorbs to upper and lower two of sound absorbing layer still is equipped with on the surface inhales the sound hole, further strengthens absorbing effect.
Description
Technical field
The utility model relates to disintegrating machine, particularly quiet impact breaker.
Background technology
Impact breaker utilizes the pivotal tup of high speed to impact material, makes it broken along the fragile part such as self-open, bed plane and joint plane.Material is subject to tup, the repeat impact of counterpunch board and mutual collision, can send loud, sharp-pointed, noisy noise, produces noise pollution, destroys normal working environment, affect normal work and the rest of workman.
Therefore it is low to need to design a noise, quiet impact breaker.
Utility model content
The utility model proposes quiet impact breaker, solve the defect that in prior art, impact breaker noise is large.
The technical solution of the utility model is achieved in that
Quiet impact breaker, comprise casing, be provided with central shaft and counterpunch board in casing, central shaft is provided with disk, disk is provided with tup, casing is also provided with charging aperture, charging aperture is provided with rotating shaft, and rotating shaft is provided with hush panel, and the outer surface of hush panel and casing is also provided with reflection sound absorbing layer, reflection sound absorbing layer comprises sound-absorbing sponge layer and reflecting layer, and sound-absorbing sponge layer upper surface and lower surface are equipped with the sound-absorption hole of indent.
Further, described rotating shaft is also provided with torsionspring, two butt bars of torsionspring lean against on described hush panel and described charging aperture respectively.
Further, the sound-absorption hole interlaced arrangement of described sound-absorbing sponge layer upper surface and lower surface.
Further, described reflecting layer be PET material make spin cloth-like structure.
Further, described sound-absorption hole is spheroidal.
The beneficial effects of the utility model: charging aperture of the present utility model is provided with hush panel, can move around rotating shaft, can completely cut off the noise spread out of in casing to a certain extent; And in hush panel and casing, be also provided with reflection sound absorbing layer, sound-absorbing sponge layer on reflection sound absorbing layer can absorb in casing the noise spreading out of and, the noise that residue does not absorb, after sound-absorbing sponge layer, returned by reflective layer reflects again, again absorbed by sound-absorbing sponge layer, and upper and lower two of sound absorbing layer are also provided with sound-absorption hole on the surface, strengthen sound-absorbing effect further.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the quiet impact breaker of the utility model;
Fig. 2 is the structural representation of reflection sound absorbing layer.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1-2, quiet impact breaker, comprises casing 1, is provided with central shaft 2 and counterpunch board 3 in casing 1, central shaft 2 is provided with disk 4, disk 4 is provided with tup 5, casing is also provided with charging aperture 11, charging aperture 11 is provided with rotating shaft 12, rotating shaft 12 is provided with hush panel 6, the outer surface of hush panel 6 and casing 1 is also provided with reflection sound absorbing layer 7, reflection sound absorbing layer 7 comprises sound-absorbing sponge layer 71 and reflecting layer 72, and sound-absorbing sponge layer 71 upper surface and lower surface are equipped with the sound-absorption hole 73 of indent.Charging aperture 11 of the present utility model is provided with hush panel 6, can move, can completely cut off the noise spread out of in casing 1 to a certain extent around rotating shaft 12; And in hush panel 6 and casing 1, be also provided with reflection sound absorbing layer 7, sound-absorbing sponge layer 71 on reflection sound absorbing layer 7 can absorb in casing 1 noise spreading out of and, the noise that residue does not absorb, after sound-absorbing sponge layer 71, reflected by reflecting layer 72 again, again absorbed by sound-absorbing sponge layer 71, and upper and lower two of sound absorbing layer are also provided with sound-absorption hole 73 on the surface, strengthen sound-absorbing effect further.
In the present embodiment, described rotating shaft 12 is also provided with torsionspring (not shown), two butt bars of torsionspring lean against on described hush panel 6 and described charging aperture 11 respectively.When not having material to enter from charging aperture 11, hush panel 6, under the effect of torsionspring, is shut automatically, can reduce spreading out of of noise.
In the present embodiment, sound-absorption hole 73 interlaced arrangement of described sound-absorbing sponge layer 71 upper surface and lower surface.
In the present embodiment, what described reflecting layer 72 was made for PET material spins cloth-like structure.
In the present embodiment, described sound-absorption hole 73 is spheroidal.Sound-absorption hole 73 can make sound wave after entering sound-absorption hole 73 for spheroidal, multiple reflections in sound-absorption hole 73, thus the effect reaching sound-absorbing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
