| 摘要 |
The invention refers to an agricultural machine comprising a seed furrow forming device 10 and a seed out feeding device (8), which via a linkage device (6) are connected with a structural member (3) in such a way that the seed furrow forming means (10) and the seed out feeding device (8) are moveable at least partly vertically. The seed out feeding device (8) comprises a seed out feeding element (803) which by means of a drive device (401) is rotatable around a seed out feeding axle (805) and adapted to, at a distance from the seed out feeding axle (805), take and release seeds (91). The linkage device (6) is adapted to provide a gearing such that a vertical component of a movement for the seed furrow forming means (10) corresponds to by a smaller vertical component of a movement for the seed out feeding device (8). The drive device (401) is adapted to increase the rotational velocity of the seed out feeding element (803) at an upward-directed relative movement of the seed out feeding device (8), and to decrease the rotational velocity of the seed out feeding element (803) at a downward-directed relative movement of the seed out feeding device (8). |
