There is protrusion, the protrusion is uniformly provided with around the center of annular slab, and the bottom of the outside shell is fixedly connected with protrusion, described
The lower end of thin wire gauze is connected with the upper end of outside shell, the upper end of the thin wire gauze and the fixed company of the outer edge of taper top shell
It connects.
As an improvement, the lower end of the blade extends at the lower end outer rim of cone, the upper end of the blade is extended to
The lower section on cone top, the quantity of the blade are not less than three, and the blade and cone are by being welded and fixed.
As an improvement, the annular slab raises upward from outside to inside.
As an improvement, the inner wall of the driving motor and cone is connected through a screw thread fixation.
As an improvement, passing through weldering between the bracket and support column by being welded and fixed between the bracket and air inlet pipe
Connect fixation.
As an improvement, the driving motor is direct current generator.
As an improvement, the material of the annular slab, outside shell and taper top shell is steel.
The utility model compared with prior art the advantages of be: when dust laden air is entered by top, pressurize, revolve through fan
Turn, under the influence of centrifugal force, dust prolongs shell downwards and is discharged by ash discharging hole, and cleaned air enters air by air inlet pipe
Filter core removes most of dust, mitigates the burden of air filtering core, extends the service life of air filtering core, reduce vehicle use at
This, protects the effect of engine.

Specific embodiment
A kind of filter of the utility model is described in further detail with prefilter with reference to the accompanying drawing.
With reference to Fig. 1-Fig. 4, a kind of filter prefilter, including housing parts, air inlet tube portion and fan section；It is described
Air inlet tube portion is by air inlet pipe 1, the bracket being arranged in inside air inlet pipe 12 and the support column 3 being arranged on bracket 2, the support
The other end of column 3 extends air inlet pipe 1；The fan section is by cone 4,5 and of the driving motor being arranged in inside cone 4
The blade 6 being arranged on 4 outer wall of cone forms, and the blade 6 is evenly distributed around the axis of cone 4, the driving electricity
The bottom of machine 5 is fixedly connected with the top of support column 3；The housing parts are by annular slab 7, outside shell 8,9 and of thin wire gauze
Taper top shell 10 forms, and the annular slab 7 is fixedly connected with the top of air inlet pipe 1, and the edge of the annular slab 7 is equipped with protrusion
11, described raised 11 are uniformly provided with around the center of annular slab 7, and the bottom of the outside shell 8 is fixedly connected with protrusion 11, institute
The lower end for stating thin wire gauze 9 is connected with the upper end of outside shell 8, the upper end of the thin wire gauze 9 and the outside of taper top shell 10
Edge is fixedly connected.
The lower end of the blade 6 extends at the lower end outer rim of cone 4, and the upper end of the blade 6 extends to cone 4
