BACKGROUND OF THE INVENTION The present invention relates to a combine grain which discharges the grain sent from a threshing unit into a grain tank mounted on a machine equipped with a traveling device and stored at an appropriate place outside the machine. The present invention relates to a grain discharging auger breaker.

[0002]

2. Description of the Related Art Conventionally, as a grain discharge auger of a combine, as disclosed in Japanese Utility Model Application Laid-Open No. 63-2445, the grain in a grain tank is turned at the time of work and is placed at an appropriate position outside the machine. When the operation is completed, the discharge auger to be discharged to the storage position is locked at the storage position.

[0003]

As described above, the conventional discharge auger locks the discharge auger at the storage position upon completion of the external discharge operation. There is no means for maintaining the discharge state when the grains in the grain tank are discharged to the right place by rotating the mower horizontally, so that the turning operation lever for rotating the graining cylinder is operated to discharge the grains. -The auger is horizontally rotated to a neutral position, the rotation is stopped and the state is discharged to an appropriate position, and the discharged auger naturally swings under its own weight while the grain is being discharged out of the machine. The discharge point shifts, causing the grains to drop to unexpected places. In particular, when the air is discharged from the discharge auger in a tilted state, the natural oscillation of the discharge auger becomes conspicuous. Therefore, in the present invention, the discharge auger is discharged to an appropriate position. For the purpose of keeping the discharge state sometimes and preventing the fall of the grain to an unexpected place due to natural swing, and to be able to intentionally change the discharge location during the discharge of the grain It was devised.

[0004]

Therefore, in the present invention, in order to achieve the above-mentioned object, a threshing unit and a kernel from the threshing unit are stored on a machine equipped with a traveling device. A rotatable fryer cylinder equipped with a grain tank and rotatable upright, and a discharge pipe extending horizontally from its upper end.
When the grain in the grain tank is discharged to an appropriate place outside the machine by using a mower, the swing of the discharged auger due to its own weight is prevented when the discharging clutch of the fryer and the discharging auger is in the "on" state. A lock mechanism is provided, and the lock mechanism is configured to unlock the discharge auger by a rotating force for horizontally rotating the discharge auger.

[0005]

With this construction, the machine is moved from the threshing unit to discharge the grains stored in the grain tank to an appropriate place outside the machine, and then the turning operation lever is operated to rotate the lifting cylinder. When the discharge auger is turned horizontally, the discharge auger is horizontally rotated to a neutral position, and the discharge clutch is turned on, and the discharge clutch is turned on in conjunction with this operation, the lock mechanism holds the discharge auger in the discharge state, and The grain in the grain tank is
The gas is discharged to a desired discharge point. In addition, when it is desired to intentionally change the discharge location during this discharge, for example, when discharging to the carrier of a transport vehicle, the turning operation lever is operated to load the discharged grains so as to equalize the discharged grains throughout the carrier. Then, when horizontal rotation power is applied to the discharge auger, the lock is released and the discharge location is changed.
