The gravel 29 or dust penetrated, which will not enter through straight hole B6 in C5, forms secondary pollution to the air in cylinder C5；Pass through several straight holes
B6 and the air for flowing through several cyclone pipes 8 form local eddy flow again through the guidance of cyclone pipe 8 and obtain certain centrifugal force again
Into in cylinder C5；Under second centrifugation, from cyclone pipe 8 come out and enter cylinder C5 in air carry smaller gravel 29 or
Dust is separated again and the reflection through cylinder C5 inner wall is quickly fallen into the collection set A16 of lower section, is completed to will enter dry type
The filtering again of the air of air filter, the filtering to air for effectively reducing dry type air filter are born.
After use after a period of time, vehicle is safeguarded, successively unscrewing thread set 25, collection set C24, collection
It covers B17 and collects set A16, then cleaning collects set A16, collects set B17 and collects the gravel 29 or dust in set C24；It is due-in
After collection set A16 is cleaned out with the gravel 29 collected in set C24 or dust, then it will successively collect set A16, collection set B17, collect
Set C24 and thread bush 25 screw on.
If the thread bush 25 in the present invention can be adjusted according to dust storm size in vehicle use process；Turn spiral shell
Line set 25 makes it along collecting the lower section of set B17 straight up or moving downward, so that thread bush 25 gradually releases or further adds
By force to the limitation of several centering blocks 21；If dust storm is big, the air entered from air inlet 4 is more containing particle, it is contemplated that air filter is not easy
When filtering is clean or exceeds filter capacity, turn thread bush 25 moves upwards and releases the limitation to centering block 21, if intervening
Under the action of the scroll spring 20 of compression, several centering blocks 21 drive several sectorial blocks 22 to swing around simultaneously respectively, collect set
The opening size of the lower end B17 is bigger, and the air in cylinder B2 is most of to be collected set B17 lower ending opening discharge for particle, and from out
The gas that port is gone out will be seldom containing grain amount, but under this measure, the air inflow of engine can be reduced, the work function of engine
Rate decline, automobile is powerless, can only slowly walk, but ensure that the safety of engine, if dust storm is very big, that is not so good as directly to stop
It gets off.If dust storm is small, turn thread bush 25 is moved downward, if the annular outer cambered surface 26 under thread bush 25 further acts on
