Claims (1)

[Scope of Claim for Utility Model Registration] 1. A grain pan 8 separates the processed material leaking from the receiving net 3 below the handling cylinder 2 based on its specific gravity, and a grain sieve 9 is continuously disposed below the rear of the grain pan 8. At the same time, the grain sieve 9
The grain sieve structure of the threshing machine is provided with a winnower 6 that can generate a sorting wind that acts on the grain sieve 9 from below the grain sieve 9, and the grain sieve 9 has filter holes for the grain sieve 9 in the direction of the sorting wind. A long hole 14 that is long along the long hole 14, and a small hole 15 that is smaller in both opening area and length in the wind direction than the long hole 14.
The grain sheave structure of the threshing machine is configured by dispersing and distributing the grains. 2 The processed material leaking from the receiving net 3 below the handling cylinder 2 is sorted by the difference in specific gravity in the grain pan 8, and the leakage is sorted by the grain sieve 9 disposed continuously below the rear of the grain pan 8. Glensieve 9
A thresher is provided with a winnowing machine 6 capable of generating a sorting wind acting from below the grain sieve 9 on the processed material, and the grain pan 8 is configured such that the rear end position of the grain pan 8 can be freely adjusted in the front and back direction. It has a grain sieve structure, and the grain sieve 9 is composed of a front sieve part 11 with a large mesh and a rear sieve part 12 with a small mesh, and the processing material filtration holes of the front sieve part 11 are arranged in the direction of the sorting wind. A grain sheave structure for a threshing machine in which a long hole 14 that is long along the long hole 14 and small holes 15 whose opening area and length in the wind direction are smaller than the long hole 14 are distributed and arranged.
