DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain discharging device for transferring grains stored in a grain tank to a truck or the like in a combine harvester.

[0002]

2. Description of the Related Art An example of a combine equipped with a grain discharging device as described above is disclosed in Japanese Patent Application Laid-Open No. 7-46938. In this combine, the grain discharging device (4, 8 in FIG. 1 of the above-mentioned publication) is configured such that the posture changing operation can be freely performed over the work position for discharging the grain and the discharging position. 2). The storage position is provided with a support portion (12 in FIG. 1 of the above publication) fixed to the machine body, and the grain discharging device is placed on the support portion at the storage position. By mounting the grain discharging device on the support portion in this manner, the grain discharging device is not shaken by the vibration of the machine body even when the combine is run.

[0003]

If the grain discharging device is configured to be mounted on the support portion at the storage position as described above, when the posture of the grain discharging device is changed to the storage position, the grain discharging device is operated. If the discharge device is accidentally placed on the support part at once, the support part and the grain discharge device may be damaged by the impact at that time. Further, when the grain discharging device is placed on the support portion at the storage position, if the posture changing operation of the grain discharging device is mistaken, the grain discharging device may not be properly placed on the supporting portion. The present invention, in a combine provided with a grain discharging device, prevents a situation in which the grain discharging device is mounted on the support portion at a stretch, or the grain discharging device cannot be mounted on the support portion well. Is intended.

[Means for Solving the Problems]

[I] According to the feature of claim 1, when the grain discharging device is operated to change the posture to the storage position side and is about to be mounted on the support portion, the alarm device is activated, so that the grain discharging device is stored in the storage position. The operator is made sufficiently aware that the posture is being changed to the side and the posture is about to be placed on the support portion. According to the feature of claim 3, when the orientation of the grain discharging device is changed to the storage position side and the grain discharging device is about to be mounted on the support portion, the grain discharging device is once stopped and then moved to the storage position side. Since it is allowed, by stopping the grain discharging device,
It is possible for the operator to sufficiently recognize that the grain discharging device is in a state where the posture changing operation is performed to the storage position side and the grain discharging device is about to be mounted on the support portion.

As a result, the operator mistakenly places the grain discharging device on the support portion at a stretch, or the worker changes the posture of the grain discharging device to the storage position side while looking aside, and the grain is discharged. There will be less chance that the ejector will not mount properly on the support. If the grain discharging device has a function of automatically changing the posture to the storage position and mounting it on the support part, if the alarm device is activated, the grain discharging device will be properly mounted on the support part. Since the operator visually confirms whether or not there is a grain discharge device, it is less likely that the worker will not notice the grain discharge device when the grain discharge device is not properly mounted on the support part and the aircraft will continue to run.

[II] According to the feature of claim 2, when the attitude of the grain discharging device is changed to the storage position side and the grain discharging device is mounted on the support portion, the grain discharging device moves to the storage position side. The speed is automatically decelerated. As a result, it is less likely that the operator will accidentally place the grain discharge device on the support portion at once, or that the operator cannot place the grain discharge device on the support portion. When the grain discharging device has a function of automatically changing the posture to the storage position and mounting it on the support part, the grain discharging device is automatically mounted on the support part with less shock.
