As the saddle structure, it has been proposed that an opening is provided at the bottom of the saddle body and the opening is closed or opened by an externally operable lid member (see, for example, Patent Document 1 below).
The cocoon structure having such a configuration is effective for removing grains and / or branch cocoons remaining at the bottom of the cocoon main body and for carrying out maintenance work on a transfer conveyor disposed at the bottom of the cocoon main body.

  However, in the eaves structure described in Patent Document 1, the lid member rotates around a pivot shaft along the width direction of the swing sorting mechanism, thereby closing the bottom opening. Since it is configured to be able to take an open position for opening the bottom opening, it is necessary to provide a rotation space for the lid member below the bottom of the heel body, and the heel body is Had to be installed in.

In particular, when the saddle structure is applied to a work vehicle such as a combine, traveling means such as a traveling crawler is positioned below the saddle structure. Therefore, when the lid member is positioned at the open position, the lid body must be installed above so that the lid member does not interfere with the running means, and the rocking body located above the lid body is not provided. The dynamic sorting mechanism and the threshing unit are also installed upward.
