Abstract
The utility model discloses a kind of used with tractor impedance composite muffler, it is characterized in that, be that the two ends of oval housing are occluding with front cover and rear end cover respectively in cross section, first space bar and the second space bar are by the inner chamber interval of housing, air inlet diffusing tube passes the intermediate portion of front cover and the first space bar, intermediate portion between rear end cover and the second space bar is provided with diffusing tube of giving vent to anger, and sound-absorbing material overlays in the inner walls between rear end cover and the second space bar.By above setting, enclosure interior of the present utility model forms multiple resonant cavity, and air-flow is eliminated the noise to high frequency audio by repeatedly turning to, and engine supercharger whistle is well eliminated.The vibration friction that the utility model makes full use of sound-absorbing material and perforated pipe is eliminated the noise, and improves the soundproof effect of silencing apparatus.
Description
Technical field
The utility model relates to a kind of tractor engine exhaust silencer, is a kind of impedance composite muffler be made up of sound-absorbing material and perforated tube specifically.
Background technique
At present, the motor silencer on tractor, noise reduction is poor, makes tractor engine noise higher, and client complains greatly, can not satisfy regulatory requirement.Require complete machine noise reduction, improve silencing apparatus simultaneously, improve the soundproof effect of silencing apparatus.
Summary of the invention
The purpose of this utility model is the used with tractor impedance composite muffler providing a kind of soundproof effect good.
To achieve these goals, the utility model is that the two ends of the housing of ellipse are occluding with front cover and rear end cover respectively in cross section, first space bar and the second space bar are by the inner chamber interval of housing, exhaust port is respectively equipped with in the both sides up and down of described second space bar, air inlet diffusing tube passes the intermediate portion of front cover and the first space bar, one end of air inlet diffusing tube is closed by the second space bar, intermediate portion between rear end cover and the second space bar is provided with diffusing tube of giving vent to anger, the one end of diffusing tube of giving vent to anger is closed by the second space bar, sound-absorbing material overlays in the inner walls between rear end cover 3 and the second space bar.
By above setting, enclosure interior of the present utility model forms multiple resonant cavity, and air-flow is eliminated the noise to high frequency audio by repeatedly turning to, and engine supercharger whistle is well eliminated.The vibration friction that the utility model makes full use of sound-absorbing material and perforated pipe is eliminated the noise, and improves the soundproof effect of silencing apparatus.
Accompanying drawing explanation
Now by reference to the accompanying drawings the utility model is described further.
Fig. 1 is this use new structure schematic diagram
Fig. 2 is the A-A sectional view of Fig. 1.
In figure: 1, housing, 2, front cover, 3, rear end cover, the 4, first space bar, the 5, second space bar, 6, exhaust port, 7, air inlet diffusing tube, 8, diffusing tube of giving vent to anger, 9, sound-absorbing material.
Embodiment
As Fig. 1, shown in 2, the utility model is that the two ends of the housing 1 of ellipse are occluding with front cover 2 and rear end cover 3 respectively in cross section, first space bar 4 and the second space bar 5 are by the inner chamber interval of housing 1, exhaust port 6 is respectively equipped with in the both sides up and down of described second space bar 5, air inlet diffusing tube 7 passes the intermediate portion of front cover 2 and the first space bar 4, one end of air inlet diffusing tube 7 is closed by the second space bar 5, intermediate portion between rear end cover 3 and the second space bar 5 is provided with diffusing tube 8 of giving vent to anger, the one end of diffusing tube 8 of giving vent to anger is closed by the second space bar 5, sound-absorbing material 9 overlays on housing 1 inwall between rear end cover 3 and the second space bar 5.By above setting, the motor noise reduction of the utility model on tractor, air inlet diffusing tube 7 is entered from the noise of engine exhaust pipe, realize one-level to eliminate the noise, noise enters housing 1 from the porous zone of air inlet diffusing tube 7 inner, realize the second level to eliminate the noise, noise enters in the housing 1 between rear end cover 3 and the second space bar 5 from the exhaust port 6 second partition 5, sound-absorbing material 9 eliminates high-frequency noise and regenerated noise, realize three grades of noise eliminations, enter finally by the porous zone of giving vent to anger on diffusing tube 8 outer wall diffusing tube 8 of giving vent to anger and discharge.
