Next, the operation will be described. The grain culm cut by the harvesting device 5 is threshed by the threshing device 6, and then fed and conveyed to the Glen tank 7 by the fried barrel 9. The grain stored in the grain tank 7 is supplied to the vertical spiral drive case 2 by the horizontal feed spiral 7a.
It is guided to the vertical spiral cylinder 12 of the discharge auger 10 via 1,
It is carried out from the vertical spiral cylinder 12 through the horizontal spiral cylinder 14 to the outside.

When the grains are discharged, the motor 29 is driven and the vertical spiral cylinder 12 is rotated via the gear 27 based on the rotation of the motor 29. By the rotation of the vertical spiral cylinder 12, the discharge auger 1
It is possible to rotate the horizontal spiral cylinder 14 of 0 to a predetermined position, whereby the grain can be transferred to a truck or the like which is laterally mounted at any position on the front, rear, left and right of the combine 1. Further, since the resin liner 22 made of polymer resin is provided at the end of the vertical spiral cylinder 12 that is fitted into the vertical spiral drive case 21, the sliding resistance when the discharge auger 10 is swung can be reduced, and the discharge auger 10 can be reduced. Can be swung smoothly.

When carrying out maintenance and inspection of the grain tank 7 and the threshing device 6, the grain tank 7 is rotated around the vertical spiral tube 12 fixed so as not to shift the vertical position.

Further, the lower end of the vertical spiral cylinder 12 is rotatably fitted and inserted into a vertical spiral cylinder fitting portion 21a of a vertical spiral drive case 21 that is rotatably fitted into a support shaft 23. Connection plate 2
Since it is fixed to the support frame 16 and the support base 26 via 5, the force acting on the vertical spiral cylinder 12 from the Glen tank 7 located on the fuselage frame 15 is higher when the grain is stored. One support plate piece 17b
It is supported by the support frame 16 via the stay 16c and the lower side thereof is supported by the support frame 16 via the connecting plate 25. Further, in the case of horizontal turning for performing maintenance / inspection of the Glen tank 7 and the threshing device 6, the force acting on the vertical spiral cylinder 12 from the Glen tank 7 located away from the machine frame 15 is higher than that of the other.

The gear 2 at the lower end of the vertical spiral cylinder 12
The pinion 29a provided on the rotary shaft of the motor 29 meshes with the motor 7 to transmit power with a large reduction ratio. However, since the rotary shaft of the pinion 29a is supported by the support base 26, it is not supported by the gear 27. The force does not cause the gear meshing state to change.

Therefore, since a member for holding the vertical spiral cylinder 12 of the discharge auger 10 can be provided with a wide span, the turning torque of the discharge auger 10 can be reduced. Further, since the motor 29, which is the vertical spiral cylinder drive section, is provided below the vertical spiral cylinder 12 to drive it, the machine body balance is not impaired. Further, the supporting frame 16, the frame 18, and the reinforcing frame 20 which are the supporting members when the Glen tank 7 horizontally turns during the work.
As a result, the vertical spiral cylinder 12 is held, so that the vertical spiral cylinder 12 can be reliably held during turning. Vertical spiral cylinder 1
Since the supporting frame 16 for supporting 2 is supported by the cutter portion 6b of the threshing device 6, the vertical spiral cylinder 1
2 can be reliably supported. Since one end of the reinforcing frame 20 is fixed to the frame 18, the other end is fixed to the frying tube 9, and the intermediate bent portion is fixed to the frame 18, the vertical spiral cylinder 12 can be reliably supported. In addition, the frame 18 and the reinforcing frame 20 are effective support members against the load when the Glen tank 7 and the threshing device 6 are horizontally rotated during maintenance and inspection. Further, since the resin liner 22 is interposed between the vertical spiral cylinder fitting portion 21a of the vertical spiral drive case 21 and the lower end of the vertical spiral cylinder 12 to be fitted therein, the resin liner 22 is rotated and the vertical spiral cylinder 12 is rotated. The load at the time of rotation of the is reduced, and it is possible to prevent the rain and dew from entering the gap.
