DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for a self-propelled threshing machine in which a threshing machine, an engine, a control section and a grain storage section are arranged on a traveling machine base.

[0002]

2. Description of the Related Art Conventionally, the above-mentioned self-propelled threshing machine is generally known, but an operator inadvertently drives the machine or rotates the threshing machine to thresh. There is a risk that each part of the machine may be damaged or even a personal injury may occur, and no security measures have been taken for such a risk.

[0003]

SUMMARY OF THE INVENTION According to the present invention, in order to eliminate the danger of the conventional self-propelled threshing machine described in the preceding section, at least the traveling clutch is "on" so that the vehicle travels. In the state, or when the threshing unit is rotating with the threshing clutch turned on, careless attempts to start the engine will not be possible, and will not cause damage to each part of the threshing machine or personal injury. It is like that.

[0004]

According to the present invention, as a first measure of the safety measure, a shielding member for covering an end of a cranking shaft of an engine can be switched between a shielding state and a non-shielding state,
"On" of the traveling clutch lever or threshing clutch lever
A configuration in which the shielding member is maintained in a shielding state via an operation member by an operation, and when the traveling clutch or the threshing clutch is “on”, the shielding member is in a shielding state and the engine cannot be started by the cranking handle. As a result, there is no need to run the machine inadvertently, nor to rotate the threshing machine, which is safe.

The switching of the shielding member to the non-shielding state can be manually performed only when the traveling clutch lever and the threshing clutch lever are turned off.
It can be confirmed at the start of the engine that both the traveling clutch and the threshing clutch are "off", and the engine can be started upon recognition of safety.

[0006] As a second measure of safety, a shielding member for covering the decompression lever of the engine is made switchable between a shielding state and an unshielding state, and the "on" operation of the traveling clutch lever or the threshing clutch lever is performed. When the traveling clutch or threshing clutch is in the "on" state, the decompressor cannot be operated and the engine cannot be started, so that the aircraft may be inadvertently run. It is safe because the threshing machine does not rotate.
