穀装置における揺動選別装置を提供することにある。However, if the overall length of the sieving line is set to be short in the above-described conventional configuration, the sieving line may be removed from the rear end portion of the sieving line onto the sifting section. When the threshing amount is small, cutting straw etc. stand up as it moves on the fine sorting, and it easily passes through the mesh etc. of the selective screening part and enters the lowermost thing collection part. Was. Also, if the total length of the sieving line is set to be long, the processed material will fall from the rear end of the sieving line to the rear side of the selective sorting section. Due to the fact that the grains were easily retained in the garbage, it was easy for the grains to fall into the second product recovery section without being separated from the straw waste. On the other hand, there is a problem that it is difficult to set the length of the sieving line to an intermediate length that does not cause the above-mentioned problem in both cases where the threshing amount is small and large. An object of the present invention is to provide an oscillating sorting device in a threshing device that can increase the sorting ability regardless of whether the threshing processing amount is large or small.

る。According to the present invention, there is provided a rocking and sorting apparatus in a threshing apparatus as described at the beginning.
The free end of the sieving wire is configured to be changeable in the longitudinal direction, and the free end of the sieving wire is displaced to the upper side in the workpiece transfer direction as the opening of the chaff sheave is increased, and the opening of the chaff sheave is opened. The point is that the chaff sheave and the sieve line are linked so that the free end of the sieve line is displaced to the lower side in the workpiece transfer direction as the degree decreases.

部へのワラ屑類の混入を防止することができる。[Function] When the threshing amount is small, the leakage opening of the chaff sheave type rough sorting section is changed to the closed side to minimize the leakage of straw chips from the rough sorting section downward. By making the free end of the sieving wire displaced to the lower side in the processing object transfer direction and increasing the effective length of specific gravity difference sorting,
It is possible to reduce the amount of straw waste that falls to the lower sorting section. And even if the straw waste falls into the sorting section,
Since it falls to the rear part of the sorting unit, the distance of the movement of the straw waste on the sorting unit is shortened, and it is possible to make it difficult for cutting straw etc. to stand during the movement, and as a result, the cutting straw etc. It is possible to prevent the waste from passing through a mesh or the like of the selective sorting unit, and prevent mixing of straw waste into the first collecting unit.

対応させて伸縮させることができる。[0006] When the threshing amount is large, the leakage opening in the chaff sheave type rough sorting section is changed to the open side, and the free end of the sieve wire is displaced to the upper side in the processing material transfer direction to enable specific gravity difference sorting. By shortening the length, the leakage of the processed material in the rough sorting section is smoothed, and the retention of the processed material on the rough sorting section is reduced as much as possible, while effectively removing straw debris by sieving sorting with a sieving line In this way, the processed material is sorted and leaked to the lower fine sorting section with little straw waste. And, even if the grains fall on the sorting while the straw is kept in the waste, they fall to the front side of the sorting section more than the case where the sieving line is long, and travel distance on the sorting section. Can be lengthened, so that it is possible to prevent an increase in the number of grains that fall into the second product recovery unit. In the above case, the free end of the sieving line is displaced to the upper side in the processing object transfer direction as the opening degree of the chaff sheave increases, and the free end of the sieving line increases as the opening degree of the chaff sheave decreases. Since the chaff sheave and the sieve line are linked so as to be displaced to the lower side in the transfer direction, the sieve line can be expanded and contracted with a simple operation in accordance with a change in the opening of the chaff sheave.

As a result, it was possible to provide a swing sorting device in a threshing device with good workability.

げる。The control device 28 controls as follows.
When the threshing amount increases, the opening degree of the chaff sheave 19 is widened, and accordingly, the free end of the sieve wire 25 is displaced to the upper side in the processing object transfer direction, and the Karamin air volume of the second Karamin 7b is changed to the large side. The opening and closing plate 3 is linked with the chaff sheave 19.
Open 3 and apply the sorting wind from the second Karamin 7b to the intermediate sorting section 17
And the selection unit 16. When the threshing amount is small, the opening of the chaff sheave 19 is narrowed, and accordingly, the free end of the sieve wire 25 is displaced to the lower side in the processing object transfer direction. In addition, the opening and closing plate 33 is closed in conjunction with the chaff sheave 19, and the sorting wind from the second Karamin 7b is carefully sorted by the sorting unit 1.
6 and the air volume of the second Karamin 7b is reduced.

別装置。1. A rough sorting section (15), which is constituted by a chaff sheave whose leak opening degree can be changed and adjusted, receives a processed material leaking from a handling chamber (2), and performs rough sorting while swinging and transferring.
While oscillating and transferring the sorted material leaked from the rough sorting section (15), the grains are sorted and leaked to the first article recovery section (8), and the second grain is disposed below the lower side in the transfer direction. A fine sorting unit (16) for dropping onto the collected second product recovery unit (9), and the coarse sorting unit (16) is provided at an upper and lower intermediate position between the rough sorting unit (15) and the fine sorting unit (16). An intermediate sorting unit (17) for sorting and dropping the grains toward the fine sorting unit (16) while rocking and transferring the sorted material leaked from 15), and sending out the waste straw toward the lower side is arranged. The intermediate sorting section (17)
Are fixedly mounted on the swinging sorting case (14), and a plurality of the fixed Glen pans (24a) are arranged in parallel with each other in such a manner that the fixed Glen pans (24a) extend in a cantilever manner along the transfer direction from the fixed Glen pan (24a) to the lower side in the transfer direction. A swing sorting apparatus in a threshing apparatus comprising a sieve line (25) and a free end of the sieve line (25) in a longitudinal direction thereof, and an opening of the chaff sheave. As the degree increases, the free end of the sieving line (25) is displaced to the upper side in the workpiece transfer direction, and the free end of the sieving line (25) increases as the opening degree of the chaff sheave decreases. An oscillating sorting device in a threshing device in which the chaff sheave and the sieving line (25) are linked so as to be displaced to the lower side in the direction of material transfer.
