Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-5, the present invention provides a technical solution: a concrete production noise reduction device comprises a silencing cover plate 1, wherein the side view of the silencing cover plate 1 is in a convex shape, a handle 3 is welded at the center position of one end of the silencing cover plate 1, a cavity 2 is formed in one end, far away from the handle 3, of the silencing cover plate 1, a first partition plate 4, a first sound absorption cotton 12, a second partition plate 13 and a second sound absorption cotton 14 are sequentially arranged in the cavity 2, the first partition plate 4 is arranged at one end, far away from the handle 3, of the cavity 2, a limit stop block 6 is arranged on one side, close to the first sound absorption cotton 12, of the first partition plate 4, a limit groove 9 and a clamping groove 7 are formed in one end, close to the first partition plate 4, of the inner wall of the cavity 2, the limit groove 9 and the clamping groove 7 are symmetrically distributed relative to the two ends of the diameter of the cavity 2, a reset spring 10 is arranged in the limit groove 9, and an anti-falling stop piece 11 is fixedly arranged at one end of the reset spring 10, anti-disengaging separation blade 11 and spacing groove 9 slidable mounting, just anti-disengaging separation blade 11 matches with one side that limit stop 6 was kept away from to first baffle 4, 4 circumference one side of first baffle are provided with fixture block 8, just fixture block 8 matches with draw-in groove 7.

In the embodiment, referring to fig. 1, 2, 3, 4 and 5, half of the noise generated in the stirring box is rebounded through the arrangement of the first partition board 4 and the sound-absorbing holes 5, so that the boom sound inside the stirring box is smaller than the boom sound inside the stirring box when most of the noise is rebounded when the noise is rebounded by half, the other half of the noise passes through the sound-absorbing holes 5 and is absorbed by the first sound-absorbing cotton 12, thereby achieving the purpose of reducing the noise, meanwhile, through the arrangement of the second partition board 13, the noise which is not absorbed by the first sound-absorbing cotton 12 can be rebounded, and is silenced again by the first sound-absorbing cotton 12, meanwhile, part of the noise which is not rebounded passes through the second partition board 13 and is absorbed by the second sound-absorbing cotton 14 to reduce the noise, thereby improving the silencing efficiency of the noise of the stirring box during the production of concrete, avoiding the occurrence of the noise disturbing people, the first partition board 4 is limited and fixed through the limit stopper 6 and the anti-falling stopper 11, when the sound absorbing hole 5 is blocked by concrete or the first sound absorbing cotton 12 is polluted by the concrete, the first partition plate 4 and the first sound absorbing cotton 12 are convenient to remove and replace.

The circumference lateral wall one end that handle 3 was kept away from to amortization apron 1 is provided with seal ring 15, limit stop 6 is the equidistant distribution of semicircle about the inner wall of cavity 2, 4 lateral walls of first baffle have been seted up and have been inhaled sound hole 5, just it is annular array distribution about first baffle 4 to inhale sound hole 5, second baffle 13 and 2 inner wall seal weld of cavity, just sound cotton 14 is sealed the setting is inhaled to the second, anticreep separation blade 11 matches with limit stop 6, just first baffle 4 sets up between anticreep separation blade 11 and limit stop 6.

The working principle is as follows: when the device is used, the device is matched with and covers the feeding hole of the stirring box, the device is fixed through friction force through the plasticity of the sealing washer 15, when the stirring box is used for stirring concrete, noise generated by the stirring box firstly passes through the first partition plate 4, so that part of the noise is rebounded, and part of the noise passes through the sound absorption hole 5, because the rebounded noise is less, the sound of the noise passing through the sound absorption hole 5 is less, the noise is absorbed and silenced by the first sound absorption cotton 12, but the sound cannot be completely eliminated by the first sound absorption cotton 12, the noise which cannot be eliminated continues to diffuse outwards, then the noise is intercepted by the second partition plate 13, so that part of the noise is rebounded, the sound is absorbed and silenced again by the first sound absorption cotton 12, the noise passing through the second partition plate 13 is absorbed and silenced by the second sound absorption cotton 14, and finally the noise passes through the sound attenuation cover plate 1 and diffuses to the outside, and at the moment, the noise is subjected to multiple silencing treatment, so that the noise is greatly reduced;

when amortization apron 1 matches with the agitator tank feed inlet, the agitator tank is at the stirring in-process, and the concrete causes easily to inhale 5 blockings up of sound hole and the cotton 12 pollution of first sound of inhaling, in order to guarantee its efficiency of making an uproar that falls, the accessible slides anticreep separation blade 11, can take off first baffle 4 and the first cotton 12 of inhaling the sound and clear up the change.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
