Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clutch operating device for a work vehicle in which an electric motor is interlocked with an operating portion of the clutch via a mechanical interlocking mechanism.

[0002]

2. Description of the Related Art In the above clutch operating device,
If the electric motor or its control device fails and the electric motor cannot be driven or controlled and the electric motor cannot operate the clutch, you can repair or replace the electric motor or the control device to operate the clutch. It was supposed to be possible.

[0003]

Conventionally, for example, when the clutch is a grain discharging auger clutch in a combine, if the electric motor or its control device fails, even if the harvesting work is continued while the electric motor is broken, If the grain tank is full by the time the repair worker arrives, the harvesting work will be interrupted at that point, and the harvesting work will be carried out until the repair worker arrives to complete the clutch repair and remove the grain. I couldn't restart. That is, if the clutch operation by the electric motor becomes impossible, the work cannot be performed until the repair is completed. SUMMARY OF THE INVENTION An object of the present invention is to provide a clutch operating device for a work vehicle that can continue the work relatively easily even if the clutch operation by the electric motor is disabled.

[0004]

The constitution, action and effect of the invention according to claim 1 are as follows.

[Structure] In a clutch operating device for a work vehicle in which an electric motor is interlocked with a clutch operating portion via a mechanical interlocking mechanism,
An oscillating link on the motor side, which is oscillated by an electric motor, and is separated from the oscillating axis of the oscillating link.
Connecting the swinging end side of the location and the operating portion of the clutch
An operating cable is provided in the mechanical interlocking mechanism, and a pipe portion having an opening on the swing end side is formed on the swing link, and the swing link is provided on the open end side of the pipe portion.
Place the pipe part so that it faces the operation panel in the covering position
And a lever guide hole that faces the open end <br/> of the pipe section along the operating range of the pipe section, are provided on the control panel.

[Operation] When the electric motor cannot operate the clutch as described at the beginning, if the electric motor can be rotated manually, the swing link on the motor side remains connected to the electric motor. However, if the electric motor cannot be rotated manually, remove the electric motor to disconnect the swing link from the electric motor, and then use the lever guide hole on the operation panel A rod
Which rod member is inserted, and the rod member is attached to the pipe part of the swing link.
After the insertion, the rod member is used as an operating lever to swing the swing link. Then, the rocking operation force is transmitted to the operation portion of the clutch by the operation cable, and the clutch can be switched.

[Effect] Even if the electric motor or the control device thereof fails, if the grain tank is full, the clutch of the grain discharging auger is artificially operated to take out the grain and restart the harvesting work. For example, you can do the work while manually operating the clutch without repairing until the scheduled work is completed, or continue the work while artificially operating the clutch until the worker arrives for repair. The work interruption time can be shortened as much as possible. In addition, it is possible to make it advantageous because it is only necessary to take a simple measure such as mounting the rod member on the pipe portion of the swing link.

The structure, operation and effect of the invention according to claim 2 are as follows.

[Configuration] In the configuration of the invention according to claim 1, the clutch is
It is a clutch that drives and stops the grain discharge auger that carries grain out of the grain tank.

[Operation] Even if the clutch cannot be operated by the electric motor, when the grain tank is full, the clutch can be artificially operated to take out the grain by the grain discharge auger. .

[Effect] Even if the electric motor or the control device thereof fails, the work is completed by artificially driving and stopping the grain discharging auger without repairing until the scheduled harvesting work is completed.
It is possible to shorten the work interruption time by continuing the harvesting work while artificially driving and stopping the grain discharge auger until the worker arrives for repair.
