摘要：
FIELD: agriculture; machine building.SUBSTANCE: pneumatic seeding apparatus comprises a hopper, a body with a drive shaft, a seed chamber and an overpressure chamber, an overpressure pipe and a sampling device. Seed chamber and overpressure chamber are connected and located inside the body between two sowing discs which are mounted on both sides of the drive shaft with the ability to move along its axis. Two grooves are provided eccentrically on the drive shaft, in grooves there are connecting ends of the arc-interrupter located in the inlet window of the body. Also on the drive shaft between the arc-interrupter and the sowing discs there are two seed sprinklers. On the outside of the sowing discs there are caps fixing the gaskets at the end surface of the sowing discs, each of which contains a protrusion located tangentially from the sampling tube to the seed level in the seed chamber. Similar protrusions are made in caps. On the seed sampling tubes, from the side facing the drive shaft, the cutting plates a
