<p>The feeder has a seed storage vessel and a movable sorting drum which can extend in a circle. A blower generates a difference of pressure between the interior of the drum and the external area of the drum, so that, if the drum has a seed supply the seeds are deposited. The seed storage vessel has two side panels separated by a distance, which extend parallel to the direction of motion of the drum and so that the drum cooperates with a seal. The sort drum (1) has a rotating sort belt (5, 12, 17) arranged opposite the drum surface (4) within a circular range of a perforation row.</p> |
