Abstract
The utility model discloses a muffler for a loader. A first end cover and a second end cover are occluded with two ends of a casing; a first partition board and a second partition board are arranged inside the casing; an air inlet pipe and an air outlet pipe with small holes are arranged on the casing; inner inserting pipes with small holes are arranged on the first partition board and the second partition board; and a sound-absorbing material is arranged on the inner side of the casing. With the structure, the utility model achieves the expected goal; the sound deadening capacity of the muffler is increased and the resistance of the muffler is reduced on the premise that the appearance of the muffler is unchanged; and in the comparison experiment of the loader, the effect is remarkable.
Description
Technical field
The utility model belongs to automobile exhaust muffler, particularly relates to a kind of exhaust silencer that uses on loader.
Background technique
Present loader silencing apparatus, its external dimension are because of a variety of causes, and be mostly fixing, and volume is very little, silencing apparatus noise elimination weak effect, and resistance height.
Summary of the invention
The purpose of this utility model is to provide a kind of impedance complex formula silencing apparatus, and it can realize high noise elimination effect and low exhaust back pressure.
The technical solution of the utility model is: be occluding with first end cap and second end cap at the two ends of housing, be provided with first dividing plate and second partition in enclosure interior, housing is provided with suction tude and foraminate steam outlet pipe, first dividing plate and second partition are provided with narrow meshed interpolation pipe, are provided with sound-absorbing material in the housing inboard.
By above setting, the utility model has reached re-set target, and under the constant prerequisite of silencing apparatus external form, the sound deadening capacity of silencing apparatus gets a promotion, and resistance descends, and in the entrucking comparative trial, effect is obvious.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described further.
Fig. 1 is the utility model structural representation
Among the figure 1, suction tude 2, first dividing plate 3, housing 4, second partition 5, sound absorbing material 6, first end cap 7, steam outlet pipe 8, interpolation pipe 9, second end cap
Embodiment
As shown in Figure 1, the utility model is occluding with first end cap 6 and second end cap 9 at the two ends of housing 3, be provided with first dividing plate 2 and second partition 4 in housing 3 inside, housing is provided with suction tude 1 and foraminate steam outlet pipe 7, first dividing plate 2 and second partition 4 are provided with narrow meshed interpolation pipe 8, are provided with sound-absorbing material 5 in housing 3 inboards.
Noise enters silencing apparatus from suction tude 1 and realizes the one-level expansion in first chamber, through on the interpolation pipe during aperture on 8, the realization aperture is eliminated the noise, then through second chamber, realize the quadratic extension noise elimination in second chamber, noise after eliminating the noise in second chamber enters the 3rd chamber through interpolation pipe 8, and in three grades of expansions of the 3rd chamber realization, realize the aperture noise elimination through the aperture on the steam outlet pipe 7 then, after steam outlet pipe 7 is discharged silencing apparatuss, noise is when three chambers realize that expansion is eliminated the noise, and the sound absorbing material that is arranged on housing 3 inwalls also absorbs sound to the medium-high frequency composition in the noise, thereby greatly reduces noise.
The utility model makes full use of sound-absorbing material, perforated pipe carries out structure optimization to silencing apparatus, and under the constant prerequisite of silencing apparatus external form, the sound deadening capacity of silencing apparatus gets a promotion, and resistance descends, and in the stand comparative trial, effect is obvious.Actual entrucking has also obtained good using effect in using.
