[0009]

Next, the operation will be described. A midway portion of the discharge auger 13 is placed on the support holder 14, and in this state, the mowing threshing work is performed, and when a certain amount of grain is threshed in the Glen tank 5, a light truck that stands by in the vicinity of the farm field Move to. Next, the discharge auger 13 is swung and moved up and down to be positioned above the tank of the light truck, and the discharge device 10, the fried grain device 11 and the discharge auger 13 in 5 are operated, and the discharge device 10 causes the fried grain device 11 to move. The grain in the grain tank 5 is transported, and the grain is discharged by the lifting device 11 to the auger 1.
3, and the discharge auger 13 is discharged to the tank of the light truck.

In this case, the discharge auger 13 is provided with an auger-side operation portion 15, and the discharge auger 13 is operated by the auger-side operation portion 15.
Can be rotated and vertically aligned, and the auger-side operation unit 15 is movable or reversible with respect to the discharge auger 13 in the length direction of the auger 13.
Alternatively, since it is provided so as to be movable in the length direction of the auger 13 with respect to the discharge auger 13 and capable of changing its direction,
The operability and workability are improved by moving the auger side operation unit 15 according to the work state. In particular, it is possible to reliably respond to position changes during work. Further, since the auger-side operation unit 15 can perform on / off operation of each device at the time of grain discharge, on / off operation of each device can be performed at appropriate timing, and operability and workability are improved. Especially,
It is possible to reliably handle emergency stop etc.

Further, the airframe side control section 6 and the auger side operation section 1
Since it is configured so that two systems of 5 and 5 can be operated, operation can be ensured even if one of them is inoperable and one becomes inoperable.
In addition, after operating the discharge auger 13 in the machine-side control unit 6 to a grain discharge state, the discharge operation is performed by the auger-side operation unit 15 of the discharge auger 13 apart from the machine-side control unit 6.
When the work is completed, the discharge auger 13 is stored and immediately returns to the fuselage-side control section 6 to perform the next work, so that one person can also perform the work. Since the auger-side operation unit 15 is attached to the slide body 17 fitted to the guide rail 16 provided on the discharge auger 13, the auger-side operation unit 15 is movable in the length direction of the discharge auger 13 and the position of the operator. The operability is improved by moving the auger side operation unit 15 in accordance with the above.
Further, since the operation box 19 is configured to be capable of changing its direction with respect to the sliding body 17, the operability is improved. That is,
Remove the pin 22 and rotate the operation box 19,
When 2 is engaged with another engagement hole 21, the operation box 19
The orientation of can be changed. Therefore, the pin 22 is engaged with the engagement hole 2
Since the auger-side operation portion 15 is firmly fixed in position because it is engaged with No. 1, the auger-side operation portion 15 is immovable for various operations and does not adversely affect the operations.

Therefore, the position change operation lever 23 for adjusting the position of the discharge auger 13 provided in the operation box 19 of the auger side operation portion 15 has the movement direction of the discharge auger 13 and the operation direction of the position change operation lever 23. Since they are configured to match, erroneous operation is prevented and operability is improved. In addition, the operation box 19 has a discharge auger 1
A discharge switch 25 and a stop switch 26 for the discharge clutch 27 for turning on and off the rotation transmitted to 3 are provided. Therefore, when the discharge switch 25 is operated, the motor 38 rotates, thereby pulling the wire 37, the wire 37 pulls one end of the arm 35 and rotates, and the other end of the arm 35 moves to the arm 31. Pin 36 of
The arm 31 is rotated around the shaft 34 against the spring 39 to bring the tension clutch pulley 30 into contact with the belt 29 to engage the clutch. Stop switch 2
When 6 is operated, the motor 38 rotates in the reverse direction and the wire 37
And the arm 31 is rotated about the shaft 34 by the elastic force of the spring 39 to disengage the tension clutch pulley 30 from the belt 29 and disengage the clutch.

Further, another arm 40 is attached to the shaft 34, the arm 40 is configured to engage with a pin 36 provided on the arm 31, and the arm 40 is provided with a manual operation provided near the seat 7. Wire 42 connected to operation lever 41
Therefore, when the manual operation lever 41 is operated, the wire 42 is pulled, the arm 40 is rotated to engage the clutch, and when the arm 40 is returned, the wire 42 is loosened, and the elasticity of the spring 39 causes the arm 42 to move. The tension clutch pulley 30 is disengaged from the belt 29 by rotating 31 around the shaft 34 to disengage the clutch. Therefore,
Regarding the operation of the tension clutch pulley 30, two operation paths are configured to ensure the operation. Also,
The tension clutch pulley 30 is a manual operation lever 41.
With respect to the model to be operated, only the motor 38 and the like are added, so that the model can be added without changing the structure and can be retrofitted.
