Accordingly, it is a technical object of the present invention to provide an operating device for a discharge auger device that solves all of these problems.

[0008]

Means for Solving the Problems To solve this technical problem, the invention described in claim 1 is directed to a discharge auger for discharging grains in a Glen tank mounted on a traveling machine such as a combine outside the machine. A discharge auger device configured such that a manual operation lever device provided in an operation section of the traveling machine body is turned on and off, so that an auger clutch for interrupting power transmission to the discharge auger is turned on or off. In the operating device, an actuator configured to actuate the manual operating lever device to the on / off operating position by power in conjunction with the initial on / off operation of the manual operating lever device is connected to the manual operating lever device.

According to a second aspect of the present invention, in the first aspect, the actuator is moved to an operating means provided at a tip of the discharge auger by turning on and off the operating means. In which the manual operation lever device is operated to the operation position of the on / off operation prior to the initial on / off operation.

Further, according to a third aspect of the present invention, in the first or second aspect, the connection of the actuator to the manually operated lever device is configured to be freely disengageable.

[0011]

According to the first aspect of the present invention, if the operator operates the manual operation lever device a little toward the entering operation position, the actuator operates the manual operation lever device in conjunction with the operation. Operate to the operating position by power. Thereby, the auger clutch is engaged and operates to transmit power to the discharge auger.

Conversely, if the operator slightly operates the manual operation lever device toward the cutting operation position, the actuator operates the manual operation lever device with power to the cutting operation position in conjunction with the operation. Let it. This allows
The auger clutch is disengaged to shut off power transmission to the discharge auger.

As described above, if the operator slightly operates the manual operation lever device toward the on / off operation position,
Since the actuator operates the manual operation lever device to the ON / OFF operation position by power in conjunction with the operation thereof, there is an effect that the ON / OFF operation of the manual operation lever device is facilitated.

According to a second aspect of the present invention, when an operator turns on and off operating means provided at the tip of the discharge auger, the actuator is given priority over the initial on / off operation of the manual operation lever device. Actuates the manually operated lever device to the ON operation position by power. Thereby, the auger clutch is engaged and operates to transmit power to the discharge auger.

Conversely, when the operator turns off the operating means, the actuator operates the power to turn the manual operating lever device to the operating position prior to the initial on / off operation of the manual operating lever device. Let it. As a result, the auger clutch is disengaged and the power transmission to the discharge auger is interrupted.

From the above, the operator can also operate the manual operation lever device to the on / off operation position by operating the operating means on the distal end side of the discharge auger, and consequently the discharge operation. This has the effect that power transmission to the auger can be cut off.

Further, according to the present invention, even if the actuator is disconnected from the manual operation lever device, if the operator operates the manual operation lever device to the on / off operation position, the auger can be used. Since the clutch can be engaged or disengaged, the power transmission to the discharge auger can be cut off by disconnecting the actuator from the manually operated lever device even if the actuator fails. This has the effect.
