SEPARATION AIR FLOW ADJUSTING MECHANISM FOR THRESHING APPARATUS

摘要

PROBLEM TO BE SOLVED: To stabilize wind force of separation air in comparison with a separation air flow adjusting mechanism for adjusting wind force of separation air flow by a fan mill fan 30 by adjusting the blocking ratio of air suction route for introducing air from an atmosphere side to an air suction zone 53 of the fan mill fan 30 and to carry out efficient separation. SOLUTION: This separation air flow adjusting mechanism for a threshing apparatus is equipped with an air escape amount adjusting means (e.g. shutter 57) for making an arbitrary amount of air in the vicinity of the air blowing zone 53 of the fan mill fan 30 blow out into a space outside a separation division part 29 or an air suction zone 53 of the fan mill fan 30.
