The present invention relates to a grain automatic packaging device, and more particularly, by automatically configured to discharge the stored grains in the bag, and does not require a separate auxiliary operator to replace the bag can be employed in a small self-deleting combine combine It relates to a grain automatic packaging device.

The combine harvester, a representative harvester, is configured to harvest grain and simultaneously thresh and sort. In particular, the combine is equipped with a grain packaging device for directly dumping the threshed and sorted grains in a bag or the grain storage tank for storing the threshed and sorted grains as it is. In most cases, the small, self-determining combine combines a grain packing device to direct the sorted grain into the bag, and the large common combine combines a large grain storage tank to store the sorted grain as it is. It is composed.

On the other hand, in the case of the self-dealing combine combines the grain packaging device is configured to immediately contain the selected grains in the bag, it is pointed out that the auxiliary worker is necessary for the replacement of the bag. In particular, a large amount of dust is generated in the process of replacing the bag, a problem occurs that the auxiliary worker inhales the generated dust to harm the health.

In consideration of this, there is a method of installing a grain storage tank capable of storing grains in a self-healing combine, and then storing the selected grains in the grain storage tank as it is, and transporting them to a trailer when the grains are full. However, this method only increases the weight of the self-dealing combine body, thereby slowing down the running and movement of the combine, resulting in only the problem of decreasing productivity. In particular, the capacity of the grain storage tank should be large enough to store at least 10 acres of grain for efficient operation. When a grain tank of such size is mounted in the combine, the combine slows down. In addition to this, the center of gravity of the combine is disturbed, making harvesting difficult, and the durability of the combine is reduced, resulting in shortening the life of the combine.

Therefore, the present invention has been made to solve the above problems, the purpose of which is to install a relatively small grain storage tank so as not to disturb and reduce the center of gravity and durability of the self-deleting combine, grain stored in the grain storage tank It is to provide a grain automatic packaging device that can efficiently contain the selected grain in the bag by the operator alone without a separate auxiliary worker by configuring to discharge the bag into the bag automatically immediately.
