The drill is designed to sow individual seed grains. The individual seed grains are transported pneumatically, and the drill mechanism has a front sowing share and a trailing pressure roller. A hose or pipe (7) is connected directly to the mechanism (3) separating the grains (8). This pipe is guided with the share (4), so that its lower end is aimed at the angle between roller and earth along the line bisecting it. The grains can be driven through the hose or pipe by compressed air from an annular nozzle (6) at its top end and the roller (5) can be guided directly behind the share. |
