| 摘要 |
The present invention provides a threshing apparatus capable of automatically and appropriately open and close a dust discharging control body by a small operating tool, easily avoiding the occurrence of failure of the operating tool, and easily and promptly performing maintenance and repair works. To achieve this purpose, a mechanical interworking tool (70) transferring a displacement toward a direction changing fitting the support intervals with respect to a continuously-variable rotary chain (21) of a transfer guide lever (22), is installed to a threshing feed chain (11) side as a displacement required for an opening/closing attitude switchover of the dust discharging control body (60). If the gap between the transfer guide lever (22) and the continuously-variable rotary chain (21) is widened, the attitude of the dust discharging control body (60) is switched to an opening attitude side. If the gap between the transfer guide lever (22) and the continuously-variable rotary chain (21) is narrowed, the attitude of the dust discharging control body (60) is switched to a closing attitude side. |
