Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention adapts sowing work of all wheat such as wheat, barley and beer barley to one type of multi-row sowing machine, and optionally uses one type of multi-row sowing machine. The present invention relates to a multi-row sowing device for wheat, which performs two types of sowing operations: dense row sowing and wide width sowing.

[0002]

2. Description of the Related Art Sowing work of wheat has been performed in the past by using a foreign-made work form and a multi-row sowing machine for dense-row sowing, which is suitable for the characteristics of the Japanese climate. Varieties of wheat and improvements have progressed, and along with this, sowing work of wheat has been improved, and now dense row sowing with a line spacing of around 15 cm,
It has been established in two types of wide sowing with a line spacing of around 30 cm.

The conventional multi-row sowing machine for wheat is a dedicated machine for dense-row sowing and wide-width sowing, and different machines are used depending on the type of wheat.

[0004]

DISCLOSURE OF THE INVENTION In the above-mentioned conventional multi-row sowing apparatus for wheat,

(1) In order to change a multi-row sowing machine for dense-row sowing with a spacing of 15 cm to a multi-row sowing machine for wide-seed with a spacing of 30 cm, skip one row in the multi-row sowing machine for dense-seeding. Although it is considered that the seeds should be fed into the seeds, it is impossible to do the work because the seeding content of the wide seeding is a pitch of 30 cm and the seeding must be wide.

Further, in a wide-row sowing machine with a wide spacing of 30 cm, the seed feeding part is assembled with a pitch of 30 cm. Therefore, this multi-row sowing machine is used for dense-row sowing with a spacing of 15 cm. It is impossible to change to a row seeder.

On the other hand, depending on the type of wheat, there are two types of work processes, dense line sowing and wide range sowing. Therefore, two types of multi-row sowing machines for dense line sowing and wide sowing are required, and the equipment cost is low. Is expensive and inconvenient to work with.

(2) Since the above-ground height of the seed feeding section of the multi-row sowing machine is high, the drop position of the seed is displaced at the start of seed sowing and at the end and start of sowing work before and after the turning of the field edge. This is a point that double seeding work may be performed at the position where the position is displaced.

[0009]
