Pneumatic single grain seeder

摘要

The seeder has a sort housing (1) comprising a seed reservoir (3), and an air feed chute attached to a perforated bottom portion for supply of pressurized air and connected to air supply lines (11) led into the sort housing. The pressurized air for creation of a fluidized bed, flows from the air feed chute into a sort region of the sort housing through the perforated bottom portion. Intermediate walls are provided with air passage apertures and arranged in the air feed chute between the air supply line and the bottom portion. The intermediate walls are designed as an air pressure comparison moderation wall and/or device.
