Pneumatic seeding machine

摘要

The machine comprises seeding shares (15,15') which are fixed in at least two lateral rows on a share rail over share holders (26) and whose seeds are supplied by pneumatic feed pipes (16). The share holders of the seeding shares on the front row are shorter than those of the seeding shares on the back row. The feed pipes are linked at the front ends (28) of the back row holders of the seeding shares (15'), and open out immediately at the share bodies (27) of the front row seeding shares (15).
