<P>PROBLEM TO BE SOLVED: To provide a selection part for a threshing apparatus, enabling a cost to be reduced by the simplification of a structure while enabling the selection operation to be carried out in a proper state even when the operation conditions are different by improving on the configuration of a grain sieve. <P>SOLUTION: The selection part for the threshing apparatus is constituted as follows. The grain sieve 81 for leaking and selecting grains is installed in a swinging selection mechanism for carrying out the selection treatment while swinging and moving a thresh-treated product, and the grain sieve 81 is equipped with a frame body 96 surrounding the outer periphery part, and perforated members 97 supported by the frame body 96 and for leaking down the grains. The grain sieve 81 has a plurality of leaking-down operation regions Z1 and Z2 divided along the conveyance direction of the treated product, and is constituted in a state in which the perforated members 97 are individually and detachably supported by each of the leaking-down operation regions Z1 and Z2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
