The utility model discloses a noise elimination bucket that microperforated panel preparation formed and the sound absorbing structure of cyclic annular cavity formation reach the noise elimination mesh to play the effect of impedance formula silencer. And simultaneously, the utility model provides an each rotatable parts all connects fixedly through the bearing to make rotatable parts realize low friction and rotate, reduced the noise source.
Description
Technical field
The utility model relates to a kind of mixed earth vibrating head, particularly relates to a kind of noise reduction and mixes earth vibrating head.
Background technology
Mention building site, what first appear in one's mind in people's brain is the roar of machine and dull tap-tap.Along with the raising that country requires living environment the attention of Noise measarement and resident, job site, building site Noise measarement has become the topic that society more and more pays close attention to.Casting and compacting of concrete, as ensureing construction quality, guaranteeing to build a shaping important step, plays not replaceable effect in construction.But resident is discontented with near the noise produced in casting and compacting of concrete process also usually causes.So many noise why is produced in casting and compacting of concrete process, its key reason is that the concrete vibration bar different design used closes green construction requirement, ignore in design and the sound source of noise is controlled, therefore, develop and use a mixed earth vibrating head possessing vibration and noise reducing function to seem particularly important.
Utility model content
The purpose of this utility model is: provide that a kind of structure is simple, sturdy and durable, the effective noise reduction that vibrates mixes earth vibrating head, this mixed earth vibrating head ensure vibrate performance prerequisite under, reduce concrete on construction site and water the noise produced when smashing, to overcome the deficiencies in the prior art.
A kind of noise reduction of the present utility model mixes earth vibrating head, comprise caput, vibrating body and excellent shell, silencing barrel is provided with in vibrating body, ring cavity is provided with between silencing barrel outer wall and vibrating body inwall, eccentric shaft is arranged in silencing barrel, and the two ends of eccentric shaft are separately fixed on clutch shaft bearing in vibrating body and the second bearing; In excellent shell, flexible shaft end is installed in excellent shell inside by the 3rd bearing, and oil sealing and seal cover are installed in the inner two ends of excellent shell simultaneously, realize the insulation blocking to whole vibrating head barred body, avoid polluting, improve the application life of concrete vibration bar; Eccentric shaft and flexible shaft end are linked together by shaft coupling, and shaft coupling is arranged on vibrating body inside by the 4th bearing.Because the two ends of eccentric shaft are separately fixed on clutch shaft bearing and the second bearing, make eccentric shaft can realize low frictional rotation in vibrating body; Meanwhile, shaft coupling is also installed in vibrating body inside by the 4th bearing, makes shaft coupling also can realize low frictional rotation in vibrating body, the noise produced when so just can reduce further whole mixed earth vibrating head work.
Aforesaid silencing barrel is the tubbiness mesh sheet be made up of microperforated panel.
Aforesaid microperforated panel is thickness of slab is 0.5 ~ 1mm, aperture is 0.5 ~ 1.5mm, perforated percentage is the metal sheet of 3 ~ 5%.
The length that the thickness of aforesaid ring cavity is 1 ~ 3cm, length is less than eccentric shaft working portion.
Owing to have employed technique scheme, the utility model has the advantage of: the silencing barrel that the utility model adopts microperforated panel to be made and the sound absorption construction that ring cavity is formed to reach noise elimination object, and play the effect of impedance muffler.In use, by regulate the aperture of microperforated panel, thickness, perforated percentage and ring cavity the degree of depth control the frequency that absorbs sound, thus obtain good soundproof effect.Meanwhile, each rotatable parts in the utility model are all connected and fixed by bearing, thus make rotatable parts realize low frictional rotation, the noise produced when reduce further whole mixed earth vibrating head work.Therefore, the utility model not only structure simple, be easy to operation, sturdy and durable, vibrate effective, and can effectively centering, high frequency noise carry out absorbing, transforming, and don't normal mechanical oscillation can be affected, thus greatly reduce the noise of vibrating head generation.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment of the present utility model: see Fig. 1, a kind of noise reduction of the present utility model mixes earth vibrating head, comprise caput 1, vibrating body 3 and excellent shell 11, silencing barrel 4 is provided with in vibrating body 3, ring cavity 14 is provided with between silencing barrel 4 outer wall and vibrating body 3 inwall, the thickness of ring cavity 14 is 1cm, and its length is less than the length of eccentric shaft 5 working portion; Eccentric shaft 5 is arranged in silencing barrel 4, and the two ends of eccentric shaft 5 are separately fixed on clutch shaft bearing 2 in vibrating body 3 and the second bearing 6; In excellent shell 11, flexible shaft end 12 is installed in excellent shell 11 inside by the 3rd bearing 10, oil sealing 9 and seal cover 13 are installed in the excellent inner two ends of shell 11 simultaneously, eccentric shaft 5 and flexible shaft end 12 are linked together by shaft coupling 7, and it is inner that shaft coupling 7 is arranged on vibrating body 3 by the 4th bearing 8.See Fig. 2 and Fig. 3, described silencing barrel 4 is the tubbiness mesh sheet be made up of microperforated panel, and microperforated panel is thickness of slab is 0.5mm, aperture is 0.5mm, perforated percentage is the metal sheet of 3%.
Vibrating head of the present utility model can use high-frequency motor as power resources, and uses flexible axle or flexible pipe to be connected carry-over moment with flexible shaft end 12.High-frequency motor slewing rate is fast, and provide oscillation power large, meanwhile, after equipped accelerator, its centrifugal force provided promotes further, and the effect that makes to vibrate leaps further; Meanwhile, vibrating head uses flexible axle or flexible pipe carry-over moment, and this conduction pattern is not only easy to operation, and conduction efficiency is high, the more important thing is, it is particularly suitable for complex environment operation, is a kind of excellent conduction pattern.
