Therefore, the tension spring 66 is deactivated by the tension restricting member, and the elevator chain 58 is loosened to facilitate the reverse rotation of the manual reverse rotation handle 61.
The configuration of the tension regulating member is arbitrary. For example, the tension spring 66 may be configured to fix the end of the tension spring 66 on the side of the tension gear 65 to the side plate of the transport elevator 17 so that the tension spring 66 cannot be shortened.
A detection sensor (not shown) for detecting the attachment of the manual reverse rotation handle 61 is provided in the vicinity of the fitting portion between the manual reverse rotation handle 61 and the driven shaft 57, and when the detection sensor detects the attachment of the manual reverse rotation handle 61, the cutting is performed. The cutting clutch (not shown) for turning on and off the transmission to the device 4 is configured not to enter.

Therefore, it is possible to prevent the reaping device 4 and the transport elevator 17 from being driven due to forgetting to remove the manual reversing handle 61 or an erroneous operation.
Further, a cam mechanism (not shown) is provided at a fitting portion between the manual reverse rotation handle 61 and the driven shaft 57 so that the manual reverse rotation handle 61 is detached from the driven shaft 57 when the driven shaft 57 rotates in the forward rotation direction. Configure.
