Behind the stock carrier 13, there is provided a supply carrier 9 that takes over and transports the grain stems conveyed from the stock carrier 13.

The reaping device 8 is supported by a reaping device supporting frame 15 which moves up and down about a fulcrum above the traveling transmission device 14 at substantially right and left intermediate portions. It is configured to move up and down together with the support frame 15. Above the undercarriage 2, a threshing device 17 having a feed chain 16 that takes over and transports the grain culm transported from the supply and transport device 9, and a Glen that temporarily stores the kernels that have been threshed and sorted by the threshing device 17. The tank 3 and an operation unit 18 for executing various operations of the combine are mounted. Behind the threshing device 17, there is provided a culm chain 19 for taking over and carrying the culm conveyed from the feed chain 16, and below the culm chain 19, a cutter device 20 for cutting the culm is provided. . Further, instead of the cutter device 20 of this embodiment, for example, another working machine such as a knotter for binding the culm may be attached.

When the amount of grains in the Glen tank 3 becomes full, the grains are discharged from the grain discharging device 21 to the outside of the machine.
The grain discharging device 21 includes a vertical auger 4 and a horizontal auger 5. A gear 22 is fixed to the base of the vertical auger 4, and a pinion 23 that meshes with the gear 22 and a motor 24 that rotates the pinion 23 are fixed to the machine body side. When the motor 24 is rotated, the vertical auger 4 turns left and right.

The horizontal auger 5 is provided with a hydraulic cylinder 25 for raising and lowering the horizontal auger 5 between the horizontal auger 5 and the vertical auger 4. The configuration is such that the horizontal auger 5 moves up and down by driving the hydraulic cylinder 25. The vertical auger 4 is configured to be fitted and supported by a transfer cylinder 27 that transfers and transports the grains transported from the lower spiral 26 in the Glen tank 3.

When the harvesting operation is performed by advancing such a combine, the culm planted in the field scene is weeded by the weeding implement 10, raised, raised in the case 11, and cut by the cutting blade. Reaped at 12. Then, the stock transfer device 1
3 and is taken over by the supply / conveyance device 9. The grain culm carried over by the supply / conveyance device 9 is further conveyed backward. Then, the culm is conveyed to the feed chain 16 of the threshing device 17 and conveyed rearward, and the culm is threshed and sorted by the threshing device 17.

The grains thus threshed and sorted are conveyed into the Glen tank 3 through the first deep-frying cylinder 28,
Stored temporarily. When the amount of grains stored in the Glen tank 3 becomes full, the operator is notified by the notification means of the operation unit 18. Then, the operator interrupts the harvesting operation and starts the operation of discharging the grains in the Glen tank 3 to the outside of the machine. The combine is moved to an arbitrary position (position near the truck), and the grain discharging device 21 is moved to the auger receiver 30.

The configuration is as follows. In such automatic storage, the horizontal auger 5 is first raised to the maximum raising position by the hydraulic cylinder 25 at the overhang position of the grain discharging device 21, and then the motor 24 is driven to drive the vertical auger 5 together with the horizontal auger 5. 4 is rotated to a position above the auger receiver 30, and then the hydraulic cylinder 25 is driven again to drive the lateral auger 5.
Is lowered to be stored in the auger receiver 30.

However, when the grain discharging device 21 is automatically moved and turned, there is a risk that the horizontal auger 5 may come into contact with an obstacle if the operator does not know. So, as mentioned above,
When automatically storing the grain discharging device 21 in the auger receiver 30 from the overhang position, the control means 100 issues an alarm. This alarm is an alarm. This allows the worker to recognize the turning movement of the grain discharging device 21, thereby enabling safe operation.

Further, if the movement and turning of the grain discharging device 21 is notified by voice, the worker can recognize the moving and turning of the grain discharging device 21 more reliably, and the burden on the worker is reduced. I do. The utterance is made by voice, for example, "the grain discharging device is moving and turning". Such utterance by voice is basically a speaker.
