The above-mentioned known example is based on the problem that when the positional relationship between the discharge auger and the auger receiver is shifted due to the removal auger being removed for maintenance or the like, and then reattached, this shift is performed. There is no description about resetting the initial position to correct the error. Therefore, since the once set position cannot be corrected, there is a problem that the turning control changes with time and cannot be accurately controlled. In addition, since a special switch is required to store the data in the memory, the structure is complicated and the cost is increased.

[0004]

The object of the present invention is to simplify the resetting of the initial position,
This is a simplified configuration for resetting.

In a combine configured to automatically turn to a position, a sensor check switch 40 for checking the operation of each sensor provided on the body such as the position detecting means 31 at a desired position of the body.
Is provided within a predetermined time after the sensor check switch 40 in the off state is intentionally turned on.
When the storage switch 41 is turned on to turn on the storage switch 41 in the off state, the position adjustment mode is set. Then, the sensor check switch 40 is turned off once, and then turned on again within a certain period of time. The storage device of the auger 29 stores the value of the position detecting means 31 in the memory 42, and is thus a turning device of the grain discharging auger in the combine configured to complete the resetting of the initial position.

[0011]

Next, the operation will be described. The present invention has the above-described configuration, and when the machine body moves forward, weeding is performed by the weeding body 7, the stalk is scraped by the scraping reel 9, and the stalk is cut by the cutting blade 8.
It is scraped by the scraping reel 9, merged with the transport elevator 11 by the auger 10, transported by the transport elevator 11, sent to the threshing device 3, and threshed.
8 and is separated from straw waste and the like by the swinging sorting device 21, is also air-selected by the air blower 20, falls to the first conveyor 22, and is stored in the Glen tank 4 by the first conveyor 22. Is done. The stored grains are discharged from the Glen tank 4 by the discharging device 26 to reach the frying cylinder 28, which flies and supplies to the discharging auger 29,
The discharge auger 29 discharges to a tank of a truck stopped near the field.

In this case, the discharge auger 29 is placed on the auger receiver 30 during harvesting and threshing, and is stored and placed.
When the grains in the Glen tank 4 are discharged, the tip of the discharge auger 29 is moved upward, and then the fryer cylinder 28 is rotated, and the tip of the discharge auger 29 is turned to fit the truck tank and then discharged. When the discharging operation is completed, the discharging auger 29 is rotated to automatically set the auger receiver 30.
However, the rotation stop position of the discharge auger 29 and the position of the auger receiver 30 may be displaced due to, for example, removal by maintenance. At this time, since the sensor check switch 40 is in the OFF state, the discharge auger 29 is stored in the auger receiver 30 within a predetermined time after the sensor check switch 40 is intentionally turned on, and the OFF storage switch provided in the auger receiver 30 is provided. When 41 is turned on, the auger receiver 30
In the position adjustment mode, the lamp provided on the operation panel is lit or an alarm sounds to confirm the position adjustment mode. In this state, the sensor check switch 40 is turned off once, and then turned on again within a certain period of time. Then, the position of the discharge auger 29 at this time is changed to the discharge auger 29.
The value of the position detecting means 31 is stored (written) in the memory (non-volatile memory) memory 42 when the auger 30 matches the auger receiver 30. Therefore, it is easy to reset the initial position at which the discharged auger 29 is fitted to the auger receiver 30. I can do it.

Therefore, when the initial position deviates from the initial setting due to various reasons such as gear wear as well as the deviation at the time of maintenance, the deviation can be corrected by resetting the initial position, and accurate control can be performed. . Further, the position of the auger receiver 30 is stored in the memory 42 by learning, or the auger receiver 3 is stored with the auger receiver 30 as a reference.
0, the positions of the cabin 5 and the straw processing device 43 are read out, and these positions are stored in the memory 42, respectively.
In the position and the position of the straw processing device 43, the upper limit sensor 44
As a result, the discharge auger 29 can be turned only when the discharge auger 29 is at the upper limit, so that an accident such as the discharge auger 29 colliding with the cabin 5 due to an erroneous operation is prevented, and operability is improved. Improve.

The cabin 5 and the straw processing device 43
The position of the sensor check switch 4 in the off state is set.
If the discharge auger 29 is adjusted to the position of the cabin 5 or the straw processing device 43 within a certain period of time after turning on 0 intentionally, a position adjustment mode of the discharge auger 29 is set, and a lamp provided on a panel of the operation unit is turned on. Alternatively, when the alarm sounds, the position adjustment mode is confirmed. In this state, the sensor check switch 40 is turned off once, and then turned on again within a predetermined time, and the position of the discharge auger 29 at this time is detected. The value is stored in the memory 42. (At the time of resetting the storage position, if the discharge auger 29 is stored in the auger receiver 30 within a predetermined time after the sensor check switch 40 is intentionally turned on,
The position adjustment mode of the auger receiver 30 is set, and in this state, the sensor check switch 40 is turned off once, and then turned on again within a certain time, so that the value of the position detection means 31 is stored in the memory 42. Sometimes. As described above, the position of the discharge auger 29 is adjusted by the sensor check switch 40, thereby reducing the number of switches and simplifying the configuration. In the embodiment shown in FIGS. 10 to 11, a flange 50 is provided at the lower part of the fryer cylinder 28 so as to protrude in the horizontal direction, and the flange 50 is guided in a so-called spiral shape having the same center and different radii. A groove 51 is formed, and the guide groove 51 is formed.
Since the engaging pin 52 attached to the tip of the arm 53 is attached to the base, the base of the arm 53 is fixed to the shaft 54, and the shaft 54 is attached to the position detecting means 31, so that the fryer cylinder 28 rotates. As a result, the flange plate portion 50 rotates, and the rotation of the flange plate portion 50 causes the engagement pin 52 engaged with the guide groove 51 to rotate about the shaft 54, and the rotation of the shaft 54 due to the rotation of the engagement pin 52. Is detected by the position detecting means 31 to detect the position of the discharge auger 29. Therefore, as in the conventional case,
Since the gear having the same diameter as that described above is not required, the entire structure can be made compact. Further, since the position detecting means 31 is located below the flange plate portion 50, it can be protected, the durability is improved, and the occurrence of failure is reduced.
