Sowing element for precision pneumatic seed drills

A sowing element for a pneumatic seed drill which transports seed in a sowing advance direction and distributes the seed on a sowing ground, the sowing element comprising:

• a selector disc for isolating the seed, the selector disc being rotatable about a rotation axis;
• a conduit for transporting the seed with an initial portion which is proximal to a position for removing the seed from the selector disc and an intermediate portion which extends in continuation of the initial portion and a terminal portion, wherein the terminal portion has a length and the initial portion and the intermediate portion combine to have a total length that is greater than the length of the terminal portion and wherein the conduit, at least in the initial portion and in the intermediate portion, is rectilinear and coaxial and has an axis which is located inside a plane which is perpendicular to the sowing ground and parallel with the sowing advance direction and in that an angle defined between a first plane which is perpendicular to the axis of the conduit in the rectilinear initial portion and rectilinear intermediate portion of the conduit and a second plane perpendicular to the rotation axis of the selector disc is between 60° and 80°;
• a pneumatic accelerator positioned between the intermediate portion and the terminal portion of the conduit and arranged along the conduit for transporting the seed;
• and
• a connection element with respect to the pneumatic seed drill, wherein the connection element is configured in such a manner that the conduit, at least in the initial portion and in the intermediate portion, is vertical when the sowing element is connected to the pneumatic seed drill.
