<P>PROBLEM TO BE SOLVED: To improve sorting performance, and reduce the third outlet loss by controlling posture of a wind separator which guides a part of sorting wind from a winnower to a chaff sieve of a swinging sorting shelf, according to the amount of the processing materials to control introducing amount of the sorting wind, and setting sieve opening angle of the chaff sieve as variable according to the increase or decrease of sorting wind. <P>SOLUTION: The thresher is provided with the winnower (22) installed downward of the swinging sorting shelf (15), and the wind separator (32) guiding a part of the sorting wind from the winnower (22) to the chaff sieve (18), wherein the wind separator (32) is posture controlled to increase the amount of sorting wind guided to the chaff sieve (18) higher as thickness of a layer of the processing materials detected by a layer thickness sensor (36) increases, and interlocking to make the space between each sheave plate (18a) of the chaff sieve (18) in the swinging direction of the swinging sorting shelf (15) wider. <P>COPYRIGHT: (C)2013,JPO&INPIT |
