Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combine seeding machine that sows seeds on the harvested land while performing harvesting and threshing operations.

In order to germinate and grow seeds by sowing on harvested land in fields that have not been tilled and leveled, it is desirable to avoid stubbles and sow on the soil between plants where roots can easily spread.

In addition, when a sowing machine is installed on the rear side of the combine to sow on the harvested land, for example, in order to thresh row-planted paddy rice while reaping a certain number of rows, and sow wheat, the sowing machine can be used to reciprocate from the right side of the field. When reaping and sowing work is carried out sequentially to the left, the reaping device installed at the front of the combine and the sowing device installed at the rear are often placed in the front and back direction and are not installed in the same manner, resulting in different sowing intervals in the reciprocating stroke. That will happen. Therefore, the present invention attempts to form an orderly sowing row by selecting the sowing position of the rear seeding device, regardless of the cutting progress position of the front reaping device.

For this reason, the present invention has taken the following technical measures. Namely, the harvesting progress direction (1' )
A combine harvester equipped with a sowing device (2) that sows seeds in the area where the reaping device (1) has left behind, and a soil covering device (3) that covers the sowing area of the sowing device (2) on the rear side so as to be adjustable in left and right movement. It was used as a seeding machine.

With this configuration, the present invention has the following technical effects. In other words, when the combine harvester is operated by advancing the machine, the front reaping device (1) reaps the grain culm, and while the rear threshing section is threshing, the sowing device (2) and the soil covering device (3) installed at the rear of the combine are harvested. When sowing is carried out on the reaped site and you want to keep the sowing rows constant and parallel to the adjacent sowing rows, adjust the left and right movement of these rows to position the sowing in a place that avoids obstacles such as stubble on the reaped site. and sow,
It is possible to proceed with the sowing work in an orderly manner by covering the soil with soil, connecting it to adjacent sowing rows, or maintaining a constant spacing. When reaping in the field in the reaping direction (a) in a reciprocating stroke, the sowing row (end) of the sowing device (2) may be in an unsuitable area, or the distance between it and the adjacent sowing row may be extremely wide. The seeding device (2
) and the soil-covering device (3) can be adjusted to move left and right, sowing and covering soil can always be done in a suitable area free of obstructions at the harvest site, which is convenient.It is less likely to be constrained by the reaping and threshing work, making the reaping and sowing work easy. This can be done.

Next, a diagram example will be explained.
