Portion space is husk rice room 2.The first gap 4, the first gap is left between the radially outer edge of sand piece 10 and mounting structure 3 respective side walls
4 airflow being used in husk rice room 2 and chaff powder are discharged.
Deflector 9 is arranged at below sand piece 10, is connected to the respective side wall of described mounting structure 3, this is led outside deflector 9
The centre of stream plate 9 has fan inlet 8.In the present embodiment, end and drive shaft 6 that deflector 9 extends towards drive shaft 6
Between leave the second gap, this second gap be fan inlet 8.
Deflector 9 upper surface is highly equal plane, and that is, its plane is perpendicular to drive shaft 6 axis.In addition, deflector
9 upper surfaces are alternatively the conical surface at the high middle part in edge bottom, and the incline structure being so designed that is more beneficial for the row of air current flow and chaff powder
Go out.
Fan blade assembly 7 is installed on drive shaft 6, between deflector 9 and base plate 32.Refer to Fig. 2, fan blade
Assembly 7 includes blade axle sleeve 71 and several blades circumferentially spaced along blade axle sleeve 71 being set in drive shaft 6
72.When blade axle sleeve 71 is sheathed on drive shaft 6, both axis overlap.Blade 72 is bearing of trend and blade axle sleeve 71 axis
Platy structure or other general centrifugal fan blade structure that line (i.e. the axis of drive shaft 6) overlaps.Blade exists
Rotate around the axis of drive shaft 6 in the presence of drive shaft 6.
Refer to Fig. 3, as preferred embodiment, described fan blade assembly 7 also includes covering and is connected to this blower fan
The blade base plate 75 of blade assembly 7 Leaf 72 lower limb.As further preferred embodiment, this fan blade assembly 7
Blade 72 upper edge is provided with annular slab 74, this annular slab 74 and described blade axle sleeve 71 keep between the 3rd of setpoint distance the
Gap 73.
The position that mounting structure 3 corresponds to fan blade assembly 7 is provided with least one the row's chaff for discharging chaff powder
Mouth 5.The side wall of corresponding fan blade assembly 7 position of mounting structure 3 is referred to as blower fan shell side wall 33, the side of corresponding husk rice room 2 position
Wall is referred to as husk rice room side wall 31.Specifically, the side wall between base plate 32 and deflector 9 be blower fan shell side wall 33, deflector 9 and top
Side wall between plate 34 is husk rice room side wall 31.In the present embodiment, this vertical rice whitening machine includes row's chaff mouth 5, this row's chaff mouth 5
It is arranged at the position that blower fan shell side wall 33 corresponds to fan blade assembly 7 neighboring.
The operation principle of this vertical rice whitening machine is:
Deflector 9, base plate 32 and blower fan shell side wall 33 form Blower Housing structure, the wind of fan blade assembly 7 and surrounding
Casing body structure composition centrifugal fan structure.The fan inlet 8 at the middle part of deflector 9 is the " air inlet being somebody's turn to do " centrifugal blower "
Mouthful ", row's chaff mouth 5 is " gas outlet " being somebody's turn to do " centrifugal blower ".During fan blade assembly 7 is with drive shaft 6 rotation, " centrifugation
Air centrifugalization in blower fan " is got rid of to edge and is discharged by " gas outlet ", is somebody's turn to do " air inlet " place of " centrifugal blower "
Assume obvious negative pressure state (relating to parameters such as the diameter of this vacuum magnitude and fan blade assembly 7, shape) to lead so that being located at
Stream plate 9 top and husk rice room 2 form sufficiently large negative pressure, and the air being in atmospheric pressure state outside charging aperture 1 is made in this negative pressure
With under be inhaled into husk rice room 2, and flow into " air inlet " of " centrifugal blower " further across the first gap 4, finally from " centrifugation wind
" gas outlet " of machine " is discharged, and forms air flow, airflow direction is as shown in the in figure direction of arrow.Husk rice room 2 is ground the chaff powder and is existed
Under this air flow rolling action promotes, can rapidly pass through the first gap 4, fan inlet 8, enter fan blade assembly 7,
Finally discharge from row's chaff mouth 5.
The technical program, under deflector 9 and fan blade assembly 7 act on, forms negative-pressure air-suction effect to husk rice room 2, can
To effectively facilitate chaff powder discharge, and then improve husk rice effect.And, fan blade assembly 7 and sand piece 10 are fixedly installed on same
Drive shaft 6, rotates around drive shaft 6 axis all under the drive of this drive shaft 6, simplifies equipment overall structure, reduces equipment system
Make cost and maintenance cost.
As another kind of implementation, this vertical rice whitening machine selects to save deflector 9 and base plate 32.Its row's chaff mouth 5 is
Mounting structure 3 lower opening (former base plate 32 position).Thus formed starting from charging aperture 1, flow through husk rice room 2, the first gap 4,
Until the air-flow of fan blade assembly.Its operation principle is identical with above-mentioned, achievable identical purpose, is not repeating.
Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.Right
For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or
Change.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or
Change among the protection domain created still in the utility model.
