(Operation) Next, the operation will be described.

The discharge auger 20 of the present invention is formed by being divided into a fixed cylinder 21 and a movable cylinder 22, and the movable cylinder 22 is configured to be movable in the transport direction with respect to the fixed cylinder 21 so that the entire length of the discharge auger 20 can be extended and contracted. Therefore, the vehicle travels with the auger receiving portion 53 on the side of the driver's seat 52 supporting the middle portion of the moving cylinder 22 of the discharge auger 20 in the reduced state. And stalk the culm with a scraping reel 6 and a cutting blade 7
The stalk is cut by sliding, the stalk is supplied to the threshing device 3, the threshing is performed in the threshing device 3, and the cutting and threshing operation is performed. Is moved near the field to the waiting light truck.

Next, the discharge auger 20 is moved up from the auger receiving portion 53, and when the discharge auger 20 is moved up to the set height, the turning cylinder 44 is extended and the pinion rack 43, the pinion gear 4
2, the fryer 3 of the fryer 19 via shaft 41, gear 40 and gear 39
6, the fixed cylinder 21 of the discharge auger 20 is swung from the storage position to the discharge position around the fry cylinder 36, and the telescopic cylinder 34 is extended, and the movable cylinder 22 is extended with respect to the fixed cylinder 21. Then, the discharge port 32 of the moving cylinder 22 is positioned above the tank of the light truck, and the discharge auger 20 is operated to release the Glen tank.
Work to discharge the grain in 18 into the tank of the light truck.

In this case, since the telescopic cylinder 34 and the turning cylinder 44 are configured to automatically extend while the discharge auger 20 is turning from the storage position to the discharge position, the turning of the discharge auger 20 is performed. And elongation are performed simultaneously,
Work efficiency is improved.

The relationship between the rotation of the discharge auger 20 and the expansion and contraction of the discharge auger 20 is
The stretching speed F1 of the discharge auger 20 is the turning speed F2 of the discharge auger 20
Automatically controlling the expansion and contraction speed of the telescopic cylinder 34 and the turning cylinder 44 so that the discharging auger 20 turns to the discharging position so that the discharging auger 20 is in the maximum extended state. Immediately after the auger 20 completes turning, the discharge operation state can be set.

Thus, when the above operation is completed and the inside of the Glen tank 18 becomes empty, the middle part of the moving cylinder 22 of the discharge auger 20 is stored and supported by the auger receiving part 53, but in preparation for the next threshing work,
At this time, the moving cylinder 22 may be forgotten to be reduced.

However, when the swivel cylinder 44 is reduced and the frying cylinder 36 of the hulling device 19 is rotated to rotate the discharge auger 20 to the retracted position, the telescopic cylinder 34 also starts to shrink at the same time, The relationship between the rotation of the discharge auger 20 and the expansion / contraction of the discharge auger 20 is such that the expansion / contraction speed F1 of the discharge auger 20 is faster than the rotation speed F2 of the discharge auger 20.
Since the expansion / contraction speed of the turning cylinder 44 is automatically controlled, when the discharge auger 20 turns and turns to the storage position, the discharge auger 20 is stored in the shortest contracted state.

Therefore, it is possible to prevent forgetting to reduce the discharge auger 20.

Thus, when the discharging auger 20 is stored and the discharging operation of the harvesting grain is completed, the cutting and threshing operation and the discharging operation are repeated as described above.

In the above case, since the automatic augment switch 55 of the driver's seat 52 is provided to move the auger 20 to the discharge position, simply turning on the automatic discharge switch 55, the control unit 62 The auger 20 is automatically moved up and stopped, and then the discharge auger 20 is turned by the turning cylinder 44. When the discharge auger 20 turns and turns to the discharge position, the discharge auger 20 is in the maximum extended state. At the same time, the discharge positioning cam 46 provided on the fryer 36 comes into contact with the discharge position detection switch 48 to automatically stop the turning cylinder 44.

In addition, since the automatic storage switch 56 of the driver's seat 52 is provided for moving the discharge auger 20 to the storage position, when the automatic storage switch 56 is turned on, the control unit 62 reduces the turning cylinder 44 to Contrary to the above, the fry cylinder 36 of the fryer 19 is rotated to rotate the discharge auger 20 to the storage position, and at the same time, the expansion / contraction cylinder 34 also starts to shrink, and the discharge auger 20 is rotated to the storage position. Then, the discharge auger
20 is the shortest minimum state, and at the same time, the storage positioning cam 47 provided on the fryer cylinder 36 contacts the storage position detection switch 49 to automatically stop the turning cylinder 44.

Thus, the turning cylinder 44 and the telescopic cylinder 34 automatically move the discharge auger 20 to the set discharge position, but align the discharge port 32 of the discharge auger 20 with respect to the upper position of the tank of the light truck. It is also possible to manually operate the manual up / down switch 57 and the like to extend / contract the turning cylinder 44 and the telescopic cylinder 34 to perform fine positioning.
