System, belong to agricultural mechanical field.
Background technology
The cleaning and sorting system of cereal harvesting machinery is typically made up of transverse axis flow fan and vibratory sieve two large divisions, wherein transverse-axis-flow
Air-flow caused by blower fan is combined with vibratory sieve mechanical oscillation, and by the crop stem entered in cleaning room, flat grain and other are miscellaneous
Thing discharges body.Due to transverse axis flow fan, air-out is uniform in the axial direction, is widely used in transverse-axis-flow combined harvester always.
Domestic cereal harvesting machinery is progressively regenerated to longitudinally axial flow threshing via transverse-axis-flow threshing and developed at present, although longitudinally axial flow threshing
With advantage, but the situation that part deficiency in draught occurs in sorting purpose is just still carried out using transverse axis flow fan.
Because the axis of longitudinal axial flow roller is vertical with transverse-axis-flow blower fan axis, linear velocity of the cereal when leaving threshing cylinder
Quickly, huge centrifugal action can be born, so that being dropped down onto under the debris such as cereal and stalk is amesiality in cleaning room.
Air volume adjustment is uniform in the axial direction for transverse axis flow fan, when using relatively low rotating speed, possibly can not produce enough air quantity
Amesiality material to be cleaned is dispelled, so as to which accumulation of the cereal on vibrating screen surface can be caused, causes seed can not pass through sieve
Hole falls into grain collecting chamber, increases cleaning loss.When producing the air quantity that can dispel accumulation side material using higher rotating speed, meeting again
Cause the material on other side compass screen surface directly to be blown out body by excessive airflow influence power, will also result in loss late and carry
It is high.
