PROBLEM TO BE SOLVED: To provide a sorting device of a threshing unit, capable of solving such problems that conventional and well-known sorting control devices have a structure in which chaff sieves of a swinging and sorting shelf are controlled as a whole by one sieve motor at once and do not have a structure in which the chaff sieves are divided into groups and then the groups of the chaff sieves are separately controlled according to amounts of sorted materials, and therefore the conventional devices do not meet actual conditions, and further the conventional devices can not conduct sorting with high accuracy. SOLUTION: This sorting device of the threshing unit is structured so that a wind guide plate 11 is positioned in the threshing unit 8 equipped with a cross flow fan 3, by being downward extended from a bottom edge part 10 of a dust collection opening 9 of the cross flow fan 3 to a space near a swinging and sorting shelf 4, a wind guide 12 is positioned on a diagonally front side of a position of a bottom edge of the wind guide plate 11, by being downward extended from the swinging and sorting shelf 4 to a space more distant than chaff sieves 13, and the chaff sieves 13 are positioned in such a manner that angles of the chaff sieves 13 on one of front and rear sides of the wind guide 12 are independently adjustable of those on the other side by making the wind guide 12 a boundary between the sides.
