The utility model relates to a kind of grain
impurity air separator, belong to grain detection technical field, including the air suction collecting
pipe,
impurity unloader,
impurity suction
pipe and air separator shell connected in turn, air separator shell is provided with grain
discharge port and grain unloading port, the grain
discharge port is through with grain unloading port, air inlet is equipped between the grain
discharge port and grain unloading port.The utility model device is connected in turn by optimization design, and air suction collecting
pipe, impurity unloader, impurity suction pipe and air separator shell form an efficient
air separation system.Grain enters air separator shell by grain discharge port, due to the setting of air inlet, so that
airflow can be uniformly applied to grain, effectively separate impurities.Outlet is set in the just above of grain unloading port, further improve the
air separation effect, ensure that grain is fully
air separation treatment before unloading.
