At the time of normal planting work, the heel / center marker 20 is erected in the left-right neutral position, and the second to fourth stages 22b to 22d of the casing 22 are housed in the first stage 22a to shorten the overall length. The kite / center marker 20 serves as an index indicating the center of the left and right sides of the aircraft. Thus, seedling planting can be performed in parallel with the previous stroke. At this time, if the index body 23 is housed in parallel with the housing 22 and fixed to the hook 25, the index body 23 does not become obstructive.
[0018]
At the time of planting work in the vicinity of the reed, the reed / center marker 20 is turned down to the reed side, and the second to fourth steps 22b to 22d of the reed 22 are pulled out according to the distance to the reed. The marker 20 is extended, and the index body 23 is removed from the hook 25 and replaced so as to be perpendicular to the housing 22. Since each stage 22a-22d of the housing 22 has the predetermined length, the distance from the machine body to the housing can be determined based on the housing 22. Based on the determination result, it is determined where the aircraft should pass in the process before the coasting process so that a space for performing the coasting process can be secured.
[0019]
In the above-described embodiment, the heel / center marker 20, which is a marker that can be rotated to the left or right with the left / right center of the aircraft as a fulcrum, indicates the distance to the object on the side of the aircraft and the left / right center of the aircraft However, apart from the heel marker, which is an index indicating the distance to the object on the side of the aircraft, a center marker that is an index indicating the left and right center of the aircraft may be provided separately. In that case, it is preferable to arrange the center marker behind the eyelid marker so as not to be a blind spot when viewed from the operator.
[0020]
【The invention's effect】
As described above, the agricultural machine according to the present invention has a marker that protrudes to the side of the aircraft and indicates the distance to the object on the side of the aircraft as a fulcrum on the left and right center of the aircraft. By providing it in a rotatable manner, it is possible to know the distance to the object on both the left and right sides of the aircraft with one marker, and by providing the marker so that it can stand upright in the left-right neutral position, the marker indicates the center of the left and right As a result, the number of markers mounted on the fuselage can be reduced and the configuration can be simplified. In this case, since the index body (23) can be accommodated in parallel with the housing (22), the index body (23) is not obstructive.
[0021]
In addition, by configuring the marker to be extendable and retractable, the marker is adjusted to an appropriate length when the marker is used as an index indicating the distance to the object on the side of the aircraft and an index indicating the left and right center of the aircraft. Therefore, it is possible to obtain results that are effective in improving the functionality and handling. In this case, the distance from the machine body to the heel can be determined based on the skeleton (22), and based on the determination result, the space before the heeling process can be secured so that the space for the rimming work can be secured. You can now decide where the aircraft should go.
