Abstract
The invention discloses an impedance composite tractor muffler comprising a housing, a gas incoming spreading pipe, a gas exhausting spreading pipe and a plurality of partitions. The housing is a cylindrical tube, two ends of the housing are provided with conical openings, the partitions are arranged inside the housing and partition the interior of the housing into a first cavity, a second cavity, a third cavity, a fourth cavity and a fifth cavity, the gas incoming spreading pipe penetrates the first cavity and the second cavity, the gas exhausting spreading pipe penetrates the fourth cavity and the fifth cavity, a plurality of meshed holes are formed in the side walls of the gas incoming spreading pipe and gas exhausting spreading pipe, the inner ends of the gas incoming spreading pipe and gas exhausting spreading pipe are located in the third cavity, and the first cavity and the fifth cavity are filled with sound absorption material. Sound absorption is performed through the cavities in different manners, the vibration and friction sound absorption of the sound absorption material and meshed holes is utilized fully, the principles of cavity cross section changes and sound wave interference are utilized, and the sound absorbing effect is improved.
Description
Technical field
The present invention relates to a kind of silencing apparatus, is a kind of used with tractor impedance composite muffler specifically.
Background technique
Tractor is agricultural machinery and implement conventional in agricultural production, but the shortcoming that tractor ubiquity noise is large at present, and common acoustic wave filter structure is simple, quieter manner is single, is therefore still difficult to noise when effectively reducing tractor work.
Summary of the invention
Object of the present invention provides a kind of quieter manner diversified and the used with tractor impedance composite muffler that soundproof effect is good.
For achieving the above object, technological scheme of the present invention is: used with tractor impedance composite muffler, comprise housing, air inlet diffusing tube, to give vent to anger diffusing tube, dividing plate, described housing is columniform tubular body, and housing two ends are provided with cone shaped opening, described enclosure interior is provided with polylith dividing plate, enclosure interior is separated into the first cavity successively, second cavity, 3rd cavity, 4th cavity, 5th cavity, described air inlet diffusing tube runs through the first cavity and the second cavity respectively, described diffusing tube of giving vent to anger runs through the 4th cavity and the 5th cavity respectively, the sidewall of described air inlet diffusing tube and diffusing tube of giving vent to anger is provided with multiple mesh, and the inner of air inlet diffusing tube and diffusing tube of giving vent to anger is positioned at the 3rd cavity, sound-absorbing material is filled with in described first cavity and the 5th cavity.
Owing to adopting technique scheme, enclosure interior is provided with polylith dividing plate, housing is divided into multiple cavity, the noise elimination of different modes is carried out by each cavity, take full advantage of the vibration friction noise elimination effect of sound-absorbing material and mesh, utilize the change of cavity cross-section and the principle of sound wave interference simultaneously, improve soundproof effect.
Accompanying drawing explanation
Now the present invention will be further described by reference to the accompanying drawings.
Fig. 1 is structural representation of the present invention.
In figure: 1, air inlet diffusing tube, 2, sound-absorbing material, the 3, first cavity, the 4, second cavity, 5, housing, the 6, the 3rd cavity, 7, dividing plate, the 8, the 4th cavity, the 9, the 5th cavity, 10, diffusing tube of giving vent to anger.
Embodiment
As shown in Figure 1, used with tractor impedance composite muffler of the present invention, comprise housing 5, air inlet diffusing tube 1, to give vent to anger diffusing tube 10, dividing plate 7, housing 5 is columniform tubular body, and housing 5 two ends are provided with cone shaped opening, housing 5 inside is provided with polylith dividing plate 7, housing 5 inside is separated into the first cavity 3 successively, second cavity 4, 3rd cavity 6, 4th cavity 8, 5th cavity 9, air inlet diffusing tube 1 runs through the first cavity 3 and the second cavity 4 respectively, diffusing tube 10 of giving vent to anger runs through the 4th cavity 8 and the 5th cavity 9 respectively, the sidewall of air inlet diffusing tube 1 and diffusing tube 10 of giving vent to anger is provided with multiple mesh, and the inner of air inlet diffusing tube 1 and diffusing tube 10 of giving vent to anger is positioned at the 3rd cavity 6, sound-absorbing material 2 is filled with in the first cavity 3 and the 5th cavity 9.
Working principle of the present invention: the noise entering silencing apparatus from engine exhaust pipe enters the first cavity 3 through air inlet diffusing tube 1, realizes one-level and eliminates the noise, eliminate part high-frequency noises; Noise enters the second cavity 4 from the first cavity 3 through the mesh of air inlet diffusing tube 1, realizes the second level and eliminates the noise, and eliminates part Low Medium Frequency noise; Noise enters the 3rd cavity 6 simultaneously, realizes three grades of noise eliminations, eliminates partial noise; Noise enters the 4th cavity 8 from the mesh of diffusing tube 10 of giving vent to anger and realizes fourth stage noise elimination; Noise enters the 5th cavity 9 from the mesh of giving vent to anger diffusing tube 10 again, under the acting in conjunction of give vent to anger diffusing tube 10 and sound-absorbing material 2, eliminate high-frequency noise and regenerated noise, finally realizes eliminating the noise.
