Description will be made below based on the flow chart of FIG.

Below, an example of the control in the case of turning is given.

First, after the start of the flow chart, in S1, it is determined whether or not the up-and-down turning operation portion 9a has been operated in the left-right direction by whether the auger left-right operation detection sensor 32 has reacted.

If it is detected that the up-and-down turning operation portion 9a has been operated in the horizontal direction, the process proceeds to S2. If the up-and-down turning operation part 9a is not operated in the horizontal direction, the control ends.

Next, in S2, the engine operation detection sensor 35 detects whether or not the engine E is operating.

If it is determined that the engine E is operating, the process proceeds to S3, and if it is determined that the engine E is stopped, the control ends.

In S3, the vertical position (height) of the lateral discharge auger 82 is detected by the auger vertical position sensor 33 . If the height of the lateral discharge auger 82 is equal to or higher than the constant value, the process proceeds to S4. If the height of the lateral discharge auger 82 is less than the constant value, the control ends.

In S4, the controller 10 starts outputting the turning motor 23 in order to turn the lateral discharge auger 82 in the lateral direction in which the operation is detected by the auger left/right operation detection sensor 32, and proceeds to S5.

In S5, the timer 60 for measuring the elapsed time determines whether or not the up/down turning operation portion 9a has been operated in the horizontal direction for a predetermined time or longer, and a signal is input from the timer 60 to the controller 10. FIG.

When it is determined by the auger left/right operation detection sensor 32 and the timer 60 that the turning operation in the same direction has been continuously input for a certain period of time or more, the process proceeds to S6. If the operation time is less than the fixed time, the process returns to S5.

In S6, the controller 10 outputs a signal to the turning motor 23 and controls the horizontal discharge auger 82 to stop turning.

After the rotation of the lateral discharge auger 82 is stopped in S6, the process proceeds to S7.

In S7, after the swinging of the lateral discharge auger 82 is stopped, the controller 10 outputs a signal to the swing motor brake 24 to apply a friction brake against the swinging movement of the lateral discharge auger 82.

After S7, control ends.

In addition, it is good also as a structure which complete|finishes control after the turning output of S6 is stopped.

Although not shown, the following configuration may be used.

In a configuration that performs control to prohibit output to the lateral discharge auger 82 under specific conditions, it is determined whether or not a signal for rotating the lateral discharge auger 82 continues to be input after control is performed to prohibit rotation. Judgment is made by the left/right operation detection sensor 32 and the timer 60 . When it is determined that the state in which the signal continues to be input is canceled and a predetermined period of time or more has elapsed since the cancellation, the control for prohibiting the turning of the lateral discharge auger 82 is canceled.

The same control as described above may be performed not only for the rotation of the horizontal discharge auger 82 but also for the vertical movement, expansion and contraction, and rotation of the discharge port portion 83 .

The horizontal discharge auger 82 is provided with a rotary type lighting 85 capable of illuminating the discharge port 83 and the transfer section A, and the lighting 85 automatically changes the irradiation position according to the situation (not shown). ).

The illumination 85 is moved by an illumination motor 86 . The illumination motor 86 may use the same power source as any motor of the actuator K related to the discharge auger 8 or the discharge port rotation motor 44, or may be a different one. Moreover, the structure which is not electric control may be sufficient.

When the storage detection sensor 84 provided in the auger receiving section 80 detects that the lateral discharge auger 82 is in the storage state, the lighting motor 86 is driven and the lighting 85 rotates so as to illuminate the transfer section A.

By inputting a signal from the storage detection sensor 84 to the controller 10 and outputting it from the controller 10 to the lighting motor 86 , the lighting motor 86 is driven and the lighting 85 is rotated.

Further, an illumination motor brake 87 is provided inside the illumination motor 86, and when the rotation time of the illumination motor 86 exceeds a certain value, a signal is input from the timer 60 to the controller 10, output to the illumination motor brake 87, and the illumination motor is turned on. 86 may be controlled to brake. By performing this control, it is possible to prevent the illumination motor 86 from rotating excessively due to an operation error by the operator or some other problem.

The lighting 85 is attached at a position that does not interfere with the vertical and horizontal discharge auger 82 , rotation, and expansion/contraction, and the discharge port 83 rotation. When the lateral discharge auger 82 is stored, it is desirable that the illumination 85 be provided between the discharge port 83 and the transfer portion A in the longitudinal direction of the machine body. The same applies not only to the lighting 85 but also to the lighting motor 86 .

When the storage detection sensor 84 no longer detects the storage state of the lateral discharge auger 82 , the lighting motor 86 drives the lighting 85 to illuminate the discharge port 83 . In addition to automatically controlling the irradiation position change, it is also possible to optionally switch to manual operation. You may add the control which can irradiate another site|part.

Another configuration of the auger operation means 9 for operating the lateral discharge auger 82 is described below.

The auger operating means 9 includes a dial operating section.

The dial operation unit is provided with a dial D, which is a dial-type member as shown in FIG. are also interlocked with each other, and driven to rotate in the left-right direction.

Since the dial D and pattern B are linked with the actual movement of the lateral discharge auger 82, the operator can easily grasp the movement of the lateral discharge auger 82, and the operational feeling is improved.

As shown in FIG. 5, around the dial D are turn switches T1 and T2 for inputting an operation to turn the horizontal discharge auger 82 in the horizontal direction, and elevation switches U1 and U2 for inputting an operation to vertically move the horizontal discharge auger 82. may be provided. The turning switches T1 and T2 and the lifting switches U1 and U2 are provided with characters and symbols so that they can be easily operated by the operator.

A signal is input to the controller 10 by operating each switch, and the controller 10 outputs a signal to the actuator K. FIG.

When the turning switch T1 is pushed, the lateral discharge auger 82 is driven to turn leftward, and when the turning switch T2 is pushed, the horizontal discharge auger 82 is driven to turn rightward. When the lift switch U1 is pressed, the lateral discharge auger 82 is lifted, and when the lift switch U2 is pressed, the lateral discharge auger 82 is lowered.

Each switch may be configured to drive the lateral discharge auger 82 only while the switch is pressed, or may be configured to drive only a fixed amount. Also, if the button is not pressed for a certain period of time or more, it may be determined that an erroneous operation or contact has occurred, and no response may be made.

Although not shown, an extension switch for extending and retracting the lateral discharge auger 82 and a rotation switch for rotating the discharge port 83 may be provided. Letters or symbols may also be indicated on the turning switch and the turning switch, and a configuration other than the switch that can be operated may be used.

In addition to the operation with the dial D, the lateral discharge auger 82 can be easily finely adjusted by pressing each switch to operate the lateral discharge auger 82 .

In the operation of the dial D and the operation of each switch, if one of the turning motion and the lifting motion is input, the other operation may not be accepted. This may be applied to the expansion/contraction motion and the rotation motion of the outlet portion 83 .

Moreover, the configuration may be such that one of the operation of the dial D and each switch is preferentially controlled.

The horizontal discharge auger 82 may be automatically extended or retracted by operating the dial D (by setting the dial D to a specific position, automatic extension or retraction can be performed, etc.).

Further, an automatic extension switch may be provided separately from the dial D, and an automatic retraction switch may be provided. A configuration other than the switch may be used to enable automatic extension and automatic retraction.

Further, when performing the automatic extending operation or the automatic retracting operation, a condition such as when the operation of the dial D is performed for a certain period of time or more may be added.

It should be noted that if there is an operation during automatic extension or automatic retraction during operation of the dial D, one of them may be prioritized and the other operation may not be accepted.

When turning the horizontal discharge auger 82 by operating the dial D, the horizontal discharge auger 82 may turn left and right only when the horizontal discharge auger 82 is at a certain angle or more.

When the automatic extension is performed, the vertical position (height) of the lateral discharge auger 82 may be at the maximum upper limit position, or the vertical position (height) may be above a certain level.

In order to prevent erroneous operation, etc., when the dial D is suddenly operated within a certain period of time, it is determined that it is an erroneous operation, and the controller 10 controls the actuator K to stop the movement of the lateral discharge auger 82. Also good.

When performing automatic extension or automatic retraction by operating the dial D, the configuration may be such that a warning sound is sounded, a lamp is turned on, or a monitor display is performed. In the configuration for lighting the lamp, a configuration for blinking the illumination 85 may be used.

During automatic retraction or automatic extension, a configuration may be adopted in which only manual operation is accepted.

When the dial D or each switch is operated during the grain discharge work, the discharge work may be interrupted, or the discharge work may be prioritized and the operation from the dial D or each switch may not be accepted.

In the automatic storage control, the configuration may be such that priority is given to the automatic storage control even during other operations related to the discharge auger 8 .

If the dial D is not adjusted to the predetermined position set in advance (if the discharge auger 82 has not reached the target position), grain discharge will not be performed even if an operation for grain discharge is performed. It is also possible to configure without

A plurality of control functions including the above controls may be provided, and the configuration may be such that these controls can be arbitrarily set.

The dial operation unit used to operate the lateral discharge auger 82 may be a jog dial (not shown). A jog dial that can be clicked may be used, and when the jog dial is clicked at a position where the lateral ejection auger 82 is to be stopped, the lateral ejection auger 82 may move corresponding to the jog dial position when clicked. Further, it may be configured such that another operation is performed when the jog dial is clicked, or a configuration in which another switch is pressed instead of clicking the jog dial itself. The auger operation means 9 may be an operation member configured by combining dials, jog dials, switches, and other operation tools.
