From the opening X provided in the body side wall 71, the rear half 8Y
Can be put in and out of the opening Y provided on the rear wall 35 of the fuselage.
So that, as before,
Put the whole large and heavy rocking sorting body in and out of the wall
The length of the swing sorting body to be handled is extremely short compared to
And lighter weight, making it much easier to get in and out.
In addition, maintenance and inspection can be performed efficiently. Therefore,
The adaptability to a large threshing machine will be extremely high. Special
In addition, as described above, the first half of the swinging sorting body 8 that has become smaller
8X so that it goes in and out of the opening X
As a result, the opening X is significantly smaller than the conventional one.
Can be formed to reduce the strength reduction of the fuselage side wall
be able to. Further, the rocking sorting body 8 in the sorting wind path S is
Both the opening X of the body side wall 71 and the opening Y of the body rear wall 35
From a wide range, and the status of clogging
Can be easily cut, and at the same time
Or take out only one of the latter half 8Y
This makes it possible to perform efficient response processing.
