Vacuum principle of the singling system


AMAZONE precision air sowing units operate according to the vacuum principle. The mechanically (ED Special) or hydraulically (ED Super) driven singling of the grains is carried out via a stripper finger which offers considerable advantages as it is virtually independent of forward speed and seed shape. The unique feature of the AMAZONE precision sowing units is the singling disc. The seeds are drawn by vacuum on to the raised holes and are delivered to the stripper. These raised holes function as an agitator because they protrude from the disc surface and thus bring a motion into the seed hopper. The raised holes have a conical shape and thus cannot be blocked by broken grains. These raised holes on the singling disc ensure that the seed leaves the disc in free fall so that it is not influenced by the disc as it turns. This is of special importance for the placement accuracy. 1 = Stripper fingers 2 = Inspection hole 3 = Opto-sensor 4 = Ejector 5 = Emptying flap for residual amounts 6 = Emptying flap 7 = Reduction flap
