BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain discharging device provided in a grain storage device or the like.

[0002]

2. Description of the Related Art Conventionally, a grain storage device such as a combine is provided with a grain discharging auger as a grain discharging device for appropriately discharging the grains in the grain storing device. The grain discharging auger is connected to the upper end of a frying unit having a vertical axis and being rotatable in the horizontal direction so as to be rotatable vertically (up and down).
In addition, the grain raising unit and the grain discharging auger have a cylindrical shape, and have a configuration in which a transport spiral for transporting the grains is rotatably mounted inside. The grains in the grain storage device are taken over from the transport spiral at the bottom of the grain storage device by the transport spiral in the fryer, transported by the transport spiral in the grain discharge auger, and discharged. It is discharged from the grain outlet at the tip of the auger.

[0003] Further, there is one in which the grain discharging auger is configured to be refractible at an intermediate portion. This is a configuration for compactly storing the long grain discharge auger when not in operation. In addition, there is one in which the grain discharge auger is configured to be extendable and contractible. This is for expanding and contracting the grain discharge auger to adjust the position of the grain discharge port at the tip end, thereby expanding the workable area of the grain discharge.

[0004]

In the above-described conventional grain discharging auger, in which the grain discharging auger is configured to be able to bend at an intermediate portion, the position of the grain discharging port can be freely adjusted. Can not be adjusted. Therefore, there is no merit at the time of grain discharging work. Further, in the grain discharge auger configured to be extendable and contractable, the structure in which the grain can be extended and contracted is complicated because the transport spiral is provided therein. Therefore, the cost is higher than the merit during the grain discharging operation.

[0005]

The present invention employs the following technical means to solve the above-mentioned problems.
That is, the first inner cylinder 2 containing the first transport spiral 1 and the second inner cylinder 5 containing the second transport spiral 3 and having the opening 4 can be connected and disconnected, and the outlet 6 Is provided so as to be slidably fitted over the outer periphery of the first inner cylinder 2 and the outer periphery of the second inner cylinder 5.

[0006]

The operation and effect of the grain discharging device according to the present invention will be described below. When discharging the grains stored in the grain storage device, first, the grain discharge device is set in a dischargeable state. The state in which the discharging operation is possible will be described below. First, the first inner cylinder 2 containing the first transport spiral 1 and the second inner cylinder 5 containing the second transport spiral 3 are connected, and the first transport spiral 1 and the second transport spiral 3 are connected. A continuous inner cylinder is formed. The outer cylinder 7 is slidably fitted in the helical axis direction over the outer circumference of the first inner cylinder 2 and the outer circumference of the second inner cylinder 5. At this time, the opening 4 of the second inner cylinder 5 and the discharge port 6 of the outer cylinder 7 are in communication.
Since the opening 4 of the second inner cylinder 5 is provided over a predetermined length in the helical axis direction, even when the outer cylinder 7 is slid and the outlet 6 is moved, the opening 4 and the outlet 6 Can maintain the communication state.

[0007] With the above structure, the grains in the grain storage device are taken over from the first transport spiral 1 to the second transport spiral 3 and transported, and are discharged from the outlet 6 through the opening 4. You. At this time, if the outer cylinder 7 is slid in the helical axis direction, the position of the discharge port 6 can be arbitrarily changed, and the efficiency of the discharge operation is increased. When the discharge operation is not performed, the fitting of the outer cylinder 7 from the outer periphery of the first inner cylinder 2 to the outer periphery of the second inner cylinder 5 is released, and the first inner cylinder 2 and the second inner cylinder 5 are disengaged. Disconnect from 5 and disconnect. As a result, the long inner cylinder can be separated into short objects, and compact storage during non-operation can be achieved.

As described above, with a simple configuration, it is possible to achieve both the expansion of the degree of freedom in adjusting the discharge position during operation and the compact storage during non-operation.
