Next, the operation of the embodiment will be described. When the machine body moves forward, the cutting unit 6 cuts the grass (weeds with the weeding body 7, stalks the culm with the scraping reel 9, cuts the stalk with the cutting blade 8, scrapes with the scraping reel 9, and uses the auger 10). Merge with the transport elevator 11
To the threshing device 3 for threshing and handling
The grains that have fallen from 8 are sorted by straw shavings and the like by the rocking sorting device 21, and are also selected by the blast by the blower Karamin 20,
It falls on the first thing conveyor 22, and is stored in the Glen tank 4 by the first thing conveyor 22. The stored grains are discharged from the Glen tank 4 by the discharging device 26 and are raised in the graining cylinder 28.
Then, the fried rice barrel 28 is fried and supplied to a discharge auger 29, and the discharge auger 29 discharges the discharged auger 29 to a tank of a truck stopped near a field. Thus, the discharging auger 29 is placed on the auger receiver 30 during the harvesting and threshing operation, and is stored and placed.
When discharging the grains in the Glen tank 4, by turning on the automatic discharge set start switch 36, the tip of the discharge auger 29 is moved upward from the auger receiver 30, and then by rotating the frying cylinder 28. Discharge auger 2
9 is turned toward the tank of the truck, and when the detected value of the position detecting means 31 matches a value preset in the memory 44, the turning of the ejection auger 29 is automatically stopped, and the tip of the ejection auger 29 is Facing above the tank. In this state, when the discharge switch 37 is turned on, the tank discharge device 26, the frying cylinder 28, and the transport device in the discharge auger 29 are operated to discharge the kernels. Start switch 3
8 is turned on, and the discharge auger 29 is turned and automatically stored in the auger receiver 30. In this case, the turning target position at which the tip of the discharge auger 29 is brought into contact with the tank of the truck is set by any one of the first switch 42 and the first switch 42 among various switches at the desired position of the fuselage (such as the operating section of the cabin 5). The second switch 43 is used to write the data in the memory 44 of the CPU 41.
5, the discharge auger 29 is turned to the discharge position where the target is located, and in this state, the first switch 42 is turned on.
Is turned on, and then the second switch 43 is turned on, the value of the position detecting means 31 at the position of the discharge auger 29 at this time is stored (written) in the memory 44, and the setting of the target position is completed. In the next discharge operation, when the automatic discharge set start switch 36 is turned on, the discharge auger 29 is automatically turned to the target position and stopped. Therefore, of the various switches provided at the desired positions of the fuselage, the first switch 42, which originally has another function, is provided.
By combining the first switch 43 with the second switch 43, a target for automatic turning of the discharge auger 29 can be set, so that it is not necessary to newly provide a switch for setting a target for automatic turning, and the cost is reduced. Also, since the target setting for the automatic rotation of the discharge auger 29 is performed less frequently, rather than providing a dedicated target setting switch, the number of switches is reduced, thereby facilitating the entire switch operation. To improve operability. In addition, the dedicated target setting switch may be pressed unintentionally to set the target, but in the present invention, since the first switch 42 and the second switch 43 are used, an erroneous operation is performed. To prevent. The first switch 42 is constituted by the sensor check switch 40 for checking the operation of each sensor provided on the body such as an automatic direction control sensor for controlling the traveling device 2. The second switch 43 is constituted by the turning stop switch 39 for urgently stopping the turning of the discharge auger 29. Therefore, when performing the discharging operation, the sensor check switch 40 which is irrelevant and has no influence is turned on, and then the turning stop switch is turned on. 39
Since the target is set by turning ON, there is no erroneous setting and erroneous operation can be prevented. Also, when the discharge auger 29 is in the vicinity of the auger receiver 30 or within an arbitrarily set range such as at a position above the fuselage, the first switch 42 and the second switch 43 may be operated. At this time, since the position of the discharge auger 29 is not stored, it is possible to prevent a target setting due to an erroneous operation and to avoid performing a target setting operation again to improve operability. In addition, since it is prevented that the target is unknowingly mistakenly set in a range such as in the vicinity of the auger receiver 30 or at a position above the fuselage, it is automatically turned to an unexpected range, and Prevent confusion from occurring. Thus, the connecting portion 4 provided at the desired position of the fuselage
6 is connected to an inspection display device 47 having a sensor check function separate from the sensor check switch 40 and the CPU 41 provided on the airframe.
Since the data of the position detecting means 31 can be stored in the memory 44 of the inspection display device 47,
Is used to avoid providing a dedicated target setting switch for the discharge auger 29, thereby reducing the number of switches, facilitating the entire switch operation, improving operability, and erroneously. Preventing the target setting is also prevented. In this case, if the operation of the first switch 42 (sensor check switch 40) is required as a premise of the storage operation by the inspection display device 47, the loss of other data due to the erroneous operation of the inspection display device 47 can be prevented. To prevent. Since the LED display unit 50 is provided in the meter panel 49 provided in the control unit and the stored position of the discharge auger 29 is displayed to be stored, the turning target stop position of the discharge auger 29 is confirmed. it can. Further, since the image display unit 51 is provided in the control unit and the predetermined time of the position of the discharge auger 29 stored in the image display unit 51 is displayed, it can be confirmed (FIG. 10). A display changeover switch 52 of the image display unit 51 is provided, and when the screen is switched by the display changeover switch 52, the stored position of the discharge auger 29 is displayed. The most important image is displayed, the target position of the discharge auger 29 can be confirmed when necessary, and a reliable operation can be performed. It should be noted that the tank discharge device 26, the frying cylinder 28,
The turning on and off of the grains during discharge of the grains by the discharge auger 29 is performed by the discharge switch 37, and the turning stop switch 3 during the automatic rotation of the discharge auger 29 by the automatic discharge set start switch 36 or the storage set start switch 38.
9 is turned on, the rotation of the discharge auger 29 is stopped, and when it is restarted, the automatic discharge set start switch 36 is again turned on.
Or, when the storage set start switch 38 is turned on, the vehicle turns toward the target position or the auger receiver 30,
