it's a s. equipment details (10) for an agricultural machine for negative charge granulatartiger substances in the form of grains (40), such as seeds revealed.the s. equipment details (10) operates on the differenzdruckprinzip and includes a housing (12) and a kornzuf u00fchrung saatgutvorrat (20) in a chamber (30).a rotatable internal dosierorgan (28) with regularly on a kurvenbahn (32) spaced pockets (34) for receiving grains (40) limits the chamber (30).the pockets (34) connect the chamber (30) with a field with a lower pressure level.by the pressure difference are grains (40) of the pockets (34).the subsequent rotation of the dosierorgans (28) along the kurvenbahn (32) to a kornabgabebereich (42) to be promoted.a pressure level in the kornabgabebereich (42) forms an air flow.the grains (40), a change in the direction of a f u00fchrungsbahn (56) of a f u00fchrungselements (54) and in the direction of a saatgutdosierleitung (26).in addition, the grains (40) by a flow of air in the saatgutdosierleitung (26) an active acceleration.the f u00fchrungsbahn (56) of the f u00fchrungselements (54), an led (38) generates airflowso almost all grains (40) and / or impurities in the kornabgabebereich zwangsgef u00fchrt along the f u00fchrungsbahn (56) of the f u00fchrungselementes (54) in the saatgutdosierleitung (26) to be cast.the kornabgabebereich (42) has a luftverbindung to chamber (30) and / or to a pipe of the air supply to the chamber (30) and / or a druckerzeugungsglied and / or saatgutdosierline (26) protrudes into the chamber (30) inside.
