PROBLEM TO BE SOLVED: To provide a threshing machine which solves the problem that the rigidity of a sieve plate of an oscillation separation shelf is low, so that the interval is changed by pressure of material to be processed entering the sieve plate to lower the separation accuracy.SOLUTION: In a threshing machine, an oscillation separation shelf 20 which separates material to be processed while transferring backward the same by a blow from a fan and longitudinal reciprocating oscillation is provided below a threshing chamber 11. In the oscillation separation shelf 20, a transfer shelf part 22 for receiving the material to be processed, a sieve 23 for separating grains from foreign matter, and a straw rack 30 are disposed side by side in order from the front. The lower side of the sieve 23 is provided with a separation net 31, and these are formed of synthetic resin material. A gathering plate 43 for guiding the material to be processed dropping from the threshing chamber 11 in the direction intersecting the transfer direction of the material to be processed in a front sieve 26 is disposed above the front sieve 26 facing the transfer terminal end of the transfer shelf part 22 in the sieve 23. In the threshing machine, the gathering plate 43 and a plurality of sieve plates 26A provided on the front sieve 26 are integrated with each other. |
