Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a normal combine grain tank device for harvesting grains such as rice, wheat and soybeans for threshing.

[0002]

2. Description of the Related Art In a combine of means for transferring grains in a grain tank to the outside by inheriting them to a discharge auger at the upper part of the machine through a lower discharge auger and a vertical discharge auger,
For example, a rotating gear provided on an auger tube of a vertical discharge auger and a driving member such as a drive motor for rotating the gear have a separate support structure.

Further, in the means for engaging the lower discharge auger and the relay discharge auger with the closing of the grain tank, one of the discharge augers is provided so as to be movable backward in the axial direction of the auger. So that there is a smooth engagement without interference.

[0004]

However, in the former case, when the vertical discharge auger is tilted, for example, the center distance between the drive gear and the rotating gear mounted on the drive motor is also changed, so that the distance between these gears increases. There is a problem that the auger cannot rotate due to tooth skipping.

Further, in the latter case, there is a problem that it is difficult to confirm the connection state between the lower discharge auger and the relay discharge auger from the outside, and the engagement state of these augers cannot be accurately grasped.

[0006]

SUMMARY OF THE INVENTION Therefore, the present invention is a combiner equipped with a vertical discharge auger and an upper discharge auger for taking out grains in a grain tank to the outside, and the upper discharge auger being rotatable about the vertical discharge auger. In the above, the auger rotation gear provided on the outer periphery of the auger cylinder of the vertical discharge auger is interlockingly connected to the drive gear of the drive member through the transmission gear, and the vertical and upper discharge augers are integrally rotatable, and the vertical discharge auger cylinder is provided. The drive member and the transmission gear are integrally supported by a guide body that rotatably supports the gear, and the relative distance between the vertical discharge auger and the drive member and each transmission gear is always kept constant to prevent tooth jumping between gears. Accurate transmission of the rotational drive force that does not occur can always be performed to ensure reliable rotation of the discharge auger.

Further, in the combine for supporting the grain tank so as to be openable to the outside of the machine, the grain lower discharge auger of the grain tank and the grain relay discharge auger engaged with and connected to the discharge auger are provided, and the discharge augers are combined. By providing one of the auger shaft ends so that it projects outward when connected, it is possible to easily and accurately check the connection between the lower and relay discharge augers when the grain tank is closed from the outside. It is possible to improve efficiency.
