[Problems to be solved by the device]

 By the way, recently, there has been a demand for high-speed operation of the combine, downsizing of the combine, and good maintainability of various devices. In order to satisfy these requirements, it is necessary to improve not only the reaper on the combine harvester side but also each part of the threshing machine mounted on the combine harvester. In addition to the handling cylinder and the processing cylinder, it is necessary to improve the swing sorting device for sorting the processed products processed by these handling cylinders.

On the swing sorting device side, however, the sorting area is reduced as much as possible in order to make the entire machine compact, and the sorting is performed in order to support high-speed work such as mowing and threshing. There is a need to increase the processing capacity and, further, to facilitate the removal of the rocking sorting device from the outside so as to improve the maintainability of the rocking sorting device.

However, the various improvements described above are mutually contradictory matters. In other words, when the sorting area of the swing sorting device is reduced to enable the downsizing of the entire machine body, When the swing sorting device has a relatively low sorting capacity and cannot handle high-speed work, on the other hand, when the swing sorting device has an increased sorting processing capability to handle high-speed work, the sorting area is It is not possible to make the entire machine compact, and when the sorting area of the swing sorting device is large, the swing sorting device becomes large in size and cannot be taken out to the outside. It becomes difficult and its maintainability deteriorates.

Therefore, by making the swing sorting device a two-stage structure to reduce the size on a plane, the entire device can be made compact and compact, but a large sorting area can be secured as the entire device, and the sorting processing capability thereof can be secured. It may be possible to increase the working speed by increasing the height, but in such a case, since the vertical height of the rocking sorting apparatus as a whole becomes high, it is necessary to perform repair and inspection work of the rocking sorting apparatus. When the entire swing selecting device is taken out from the take-out port provided on the rear side of the machine body, it becomes difficult to take it out, and there is a problem in terms of maintainability.

That is, the vertical height at the take-out port is the height of the inclined wall for sorting and handling the second object, and is arranged behind the handling cylinder or the treatment cylinder, and is below the handling chamber net or the treatment chamber foot. It is determined by the height of the lower edge of the rear wall that extends, and the vertical height cannot be made sufficiently large due to the improvement of the sorting capacity. Therefore, the swing sorting device has a two-stage structure and its overall height is high. In such a case, as described above, it is possible to make the entire machine compact and operate at high speed, but it becomes difficult to take the entire swing sorting device out of the outlet. There was a problem in terms of maintainability.

The present invention has been made in view of the above problems, and an object thereof is to make the entire machine compact and to be able to cope with high-speed work while improving maintainability. An object of the present invention is to provide a swing selection device for a thresher.
