DEVICE FOR SUPPLYING WIND FOR SEPARATING OF THRESHING APPARATUS

摘要

PROBLEM TO BE SOLVED: To improve separating performances of a threshing apparatus by a simple structure by suppressing vortexes in separating wind W and by optimizing an air flow distribution and wind direction of the separating wind W in a separating wind supplyer of the threshing apparatus. SOLUTION: This device for supplying the separating wind W of the threshing apparatus is obtained by extending an end on the downstream side of the air delivering port 3 to the upper part of the first grade grain recovering part 7 and forming a rear bent piece part bent to the lower side in the wind direction plate 4 and arranging an auxiliary straightening piece 5 formed in a slender state with a sufficiently short length in the flow channel direction in the width direction than the rear bent part at a prescribed interval above a flexion point to the rear bent piece part.
