The other sheave 12 is, as shown in FIGS. 1 and 3,
It is installed on the upper surface of the chaff sieve 9, spanning between the edges of the feed pan 8 and the stroke rack 10, and is screwed into a tapped hole (not shown) provided at the edge of the feed pan 8 and the edge of the stroke rack 10. The bolt 14 to be fitted is attached to the ear portion 13 described above.
It is removably installed on the chaff sheave 9 by inserting it through the through hole 13a and screwing it into the tapped hole.

In FIG. 1, 15 and 16 are the first and second ports provided in the lower part of the swinging sorting device 5, and 17, respectively.
18 is a cross-flow fan installed at the rear and upper side of the swing sorting device 5 to remove straw waste, etc. from above the terminal end of the straw rack 10. 1, which sucks in the grains and returns them as much as possible to the 5 directions of the oscillating sorting device by the action of splashing the grains with the blades.
9 is a return path that returns the second threshing from the second port 16 to the handling room; 20 is a waste straw conveyance belt that carries out the waste straw after threshing; 21
is a waste straw cutter that is supplied with waste straw from this waste straw conveying belt and shreds it into pieces.

前記のように構成される、この考案に係る揺動選別装置
5は、次のように用いられる。
The swing sorting device 5 according to this invention, configured as described above, is used as follows.

すなわち、稲収穫時には、ポルI〜14を抜去って前記

At this time, the sheave wire 12 a of the other sheave 12 along the direction perpendicular to the sheave bar 9 a of the chaff sheave 9 , that is, the sheave wire 12 a of the sheave bar 9 a and the sheave wire 12 a are combined to form a crimp net shape. , when only the chaff sheave 9 is present, the culm cut material that could easily pass through the elongated sheave eyes between the sheave bars 9a will not be able to easily pass through the sheaves 12 and 9.
This allows only the grains to be leaked out, and the sorting accuracy is much higher than in the conventional case.

As described above, the swing sorting device for a threshing machine of this invention is equipped with another sheave 12, which is provided with a sheave wire 12a extending in a direction orthogonal to the sheave bar 9a of the chaff sheave 9, on the chaff sheave 9 in a removable manner. When harvesting rice, the above-mentioned sheave can be removed and used in the same way as in the conventional case, and when harvesting crops such as wheat that are prone to culm breakage, the other sheave can be attached. By using this, it is possible to minimize the amount of culm cuttings mixed into the first grain, and to obtain highly accurate sorting.
