Device for seed-spacing sowing, especially of beet

摘要

The invention relates to a device for seed-spacing sowing, especially of beet, with a wheel which is arranged in front of a seed-supply container and rolls on the ground and which carries on its circumference radially displaceable sowing rams extracting the seed grains individually from a supply container and pressing them into the ground and is equipped with a ram drive, according to the invention the plunger (6) forming the sowing ram being surrounded, at its end penetrating into the ground, by a cap (26) provided with a small seed passage orifice (8) and made of permanently elastic material, a chamber (24) for receiving a seed grain (7) being formed between the cap (26) and the plunger end, and the plunger and cap being movable relative to one another in such a way that, when the plunger (6) is advanced, the seed passage orifice (8) is correspondingly widened elastically for the purpose of receiving or discharging a seed grain. <IMAGE>
