Description

[Detailed Description of the Invention] The present invention relates to a cutting height display device for a reaping rotation type combine harvester in which a driving operation section is installed at the rear of the machine body.

Conventionally, there has been a technique (for example, Japanese Utility Model Application Publication No. 122507/1983) in which a non-rotating side marker and a rotating side marker are attached to a tractor to indicate the plowing depth of a rotary work machine.

However, in the prior art, each of the markers is used to interrupt plowing in the middle of the work and adjust the plowing depth. In agricultural machinery where the amount of paddy taken out to the pedestal increases during work, it is necessary to monitor the cutting height state and the paddy removal state almost simultaneously, making it difficult to easily transfer the above-mentioned conventional technology to combine harvesters. .

Therefore, in particular, in a combine harvester, a reaping device is installed in front of the threshing machine so that it can be raised and lowered, a paddy holder is attached to one side of the threshing machine, and an operating unit is provided at the rear of the paddy holder. Since it was located at the rear of the machine, it was difficult to check the support height of the reaping device, making it difficult to make an appropriate judgment on the cutting height.At the same time, it was necessary to monitor the paddy holder.
This made harvesting work extremely complicated.

The present invention solves the above-mentioned conventional drawbacks, and includes a non-rotating side marker that is integrally connected to the thresher and a rotating side marker that is integrally connected to the reaping device in front of the paddy holder. , arranged on a straight line connecting the paddy holder and the operating section, and configured so that the paddy holder and each of the markers can be visually viewed almost simultaneously by the operator of the operating section, and the mowing height by each of the markers is At the same time as the monitoring, the paddy removal state of the paddy holder can be monitored, and the operator at the operation control section can promptly deal with any inconvenient situation with the marker and the paddy holder during the work, for example, if the cutting height is outside the adjustment range. To provide a cutting height display device for a combine harvester, which can display the cutting height on a marker at the paddy rack, prevent excessive removal of paddy from the paddy holder, etc., and enable continuous and safe harvesting work. This is what I am trying to do.
