Background technique
Currently, existing engine exhaust muffler mainly uses the resistance exhaust of pipeline section expansion and cross-sectional constriction to disappear
Sound device structure, using sound wave due to the variation of acoustic reactance at the abrupt change of cross-section, some sound wave is reflected back to sound source, and obstructed
The outlet of silencer is crossed, to achieve the purpose that noise elimination.This resistance exhaust silencer centering, low-frequency silencing noise have one
Determine effect.And the uncombusted Mars for being mingled in tail gas, due to the internal structure for eliminating Mars without arrangement, it is to tail gas
In the uncombusted Mars that is mingled with eliminate it is undesirable.
Summary of the invention
The purpose of the present invention is to provide a kind of harvest machinery fire extinguishing star silencer.
To achieve the above object, the technical solution of the present invention is as follows: a kind of harvest machinery fire extinguishing star silencer, including shell
Body, air inlet diffuser, outlet exhaust pipe, air inlet partition, intermediate bulkhead and outlet partition, the shell left and right ends are installed respectively
There are drive end bearing bracket and rear end cap, the rear end cap is fixed on shell by blanking cover, and the enclosure interior is from left to right successively installed
Have air inlet partition, intermediate bulkhead and outlet partition, form the first cavity between the drive end bearing bracket and air inlet partition, the air inlet every
The second cavity is formed between plate and intermediate bulkhead, and third cavity, the outlet are formed between the intermediate bulkhead and outlet partition
The 4th cavity is formed between partition and rear end cap, and net circle is installed on the third cavity inner wall, is filled with and goes out in the net circle
Guncotton；
The air inlet diffuser is mounted between drive end bearing bracket and air inlet partition, and right end passes through air inlet partition and extend into the second cavity
It is interior, multiple air inlet diffuser ventholes are equipped on the outer wall of air inlet diffuser；
The outlet exhaust pipe from left to right sequentially passes through the second cavity, third cavity and the 4th cavity, end and passes through blanking cover
It is fixed on rear end cap.
Preferably, the outlet exhaust pipe is located at third cavity and the outer wall of the 4th cavity is vented equipped with outlet
Pipe venthole.
Preferably, the intermediate bulkhead is equipped with blinds fenestra, it is equipped on the air inlet partition and outlet partition general
Logical circle mesh.
Due to the adoption of the above technical scheme, the invention has the benefit that the present invention is able to achieve motor exhaust is eliminating the noise
Rotation is generated in silencer under the flow disturbing effect of device internal partition, generates centrifugal force, and the Mars in motor exhaust is being centrifuged
It is thrown under the action of power on the fire extinguishing cotton of silencer, fire extinguishing cotton can store and extinguish Mars, can remove in exhaust
The Mars being mingled with.The risk that Mars causes fire is generated at work to reduce harvest machinery.

Specific embodiment
As illustrated in fig. 1 and 2, the present invention includes shell 1, air inlet diffuser 2, outlet exhaust pipe 3, air inlet partition 4, middle interval
Plate 5 and outlet partition 6,1 left and right ends of shell are separately installed with drive end bearing bracket 7 and rear end cap 8, and the rear end cap 8 passes through stifled
Lid 9 is fixed on shell 1, and air inlet partition 4, intermediate bulkhead 5 and outlet partition are from left to right sequentially installed with inside the shell 1
6, the first cavity 10 is formed between the drive end bearing bracket 7 and air inlet partition 4, and is formed between the air inlet partition 4 and intermediate bulkhead 5
Two cavitys 11, form third cavity 12 between the intermediate bulkhead 5 and outlet partition 6, the outlet partition 6 and rear end cap 8 it
Between form the 4th cavity 13, net circle 14 is installed, filled with fire extinguishing cotton 15 in the net circle 14 on the third cavity inner wall；
The air inlet diffuser 2 is mounted between drive end bearing bracket 7 and air inlet partition 4, and right end passes through air inlet partition 4 and extend into second
In cavity 11, multiple air inlet diffuser ventholes 16 are equipped on the outer wall of air inlet diffuser 2；
The outlet exhaust pipe 3 from left to right sequentially passes through the second cavity 11, third cavity 12 and the 4th cavity 13, and end is logical
Blanking cover 9 is crossed to be fixed on rear end cap 8.
The outlet exhaust pipe 3 is located at third cavity 12 and the outer wall of the 4th cavity 13 is logical equipped with outlet exhaust pipe
Stomata 17.
The intermediate bulkhead 5 is equipped with blinds fenestra 18, is equipped with common circle on the air inlet partition 4 and outlet partition 6
