Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a speed change operating means for changing the traveling speed of a vehicle body, and a moving means for moving a reaping section provided on the vehicle body in the width direction of the vehicle body. This invention relates to a reaping harvester equipped with a reaping machine.

[Conventional technology]

In the above-mentioned reaping/harvesting machine, for example, when mowing with the uncut husk culm in the left hand, the reaping section is extended to the left side of the vehicle body, and the distance between the uncut husk culm and the traveling device is widened. This prevents the uncut culm from being pushed down by the mud pushed out by the traveling device. In addition, when performing intermediate splitting work with uncut husk culms located on both the left and right sides, the reaping section is set at a position midway between the left and right sides of the vehicle body to prevent the uncut husk culms from being stepped on. Furthermore, the positional deviation between the reaping section and the planted culm to be reaped in the width direction of the vehicle body is detected, and the positional deviation is corrected by moving the reaping section in the width direction of the vehicle body. The setting may be adjusted to an appropriate position for the planted culm to be harvested.

In other words, the position of the reaping section in the width direction of the vehicle body at the end of the reaping operation fluctuates, but conventionally, the position of the reaping section in the width direction of the vehicle body after the reaping operation is finished is manually adjusted. It was something that would happen.

[Problem to be solved by the invention]

With the above-mentioned conventional technology, there is a danger when driving on the road after the reaping work is completed.

In other words, the reaping operation may end with the reaping section protruding across the width of the vehicle body.

When the vehicle is driven on the road with the reaping section in the same position, there is an increased risk that the reaping section will come into contact with an object on the road.

An object of the present invention is to eliminate the above-mentioned conventional drawbacks and to obtain a highly safe reaping and harvesting machine.

[Means to solve the problem]

In order to achieve this object, the reaping and harvesting machine according to the present invention has a characteristic configuration including a reaping operation state detection means for detecting whether reaping operation is in progress, and a speed change operation detection means for detecting a switching operation of the speed change operation means. is provided, and based on the detection information of the reaping work state detection means and the speed change operation detection means, when it is detected that the reaping work state is not in the reaping work state and the high speed shift state is in the high speed shift state, the reaping section is moved to the set position. A control means is provided for operating the moving means so as to locate the moving means.

[For production]

When the reaping harvester is traveling on the road, it is considered to be in a non-reaping operation state and normally in a high speed change state.

Therefore, as the vehicle travels on the road, the reaping section can be positioned at the set position.

By the way, the setting position is set at a position intermediate between the left and right sides of the vehicle body so that the reaping portion does not protrude laterally of the vehicle body.

〔Effect of the invention〕

Since the reaping part can be reliably moved to a position where it does not protrude laterally to the vehicle body when driving on the road, safety when driving on the road can be improved.
