MANIFOLD AND DISTRIBUTION MANIFOLD ASSEMBLY FOR MATERIAL TRAPPED BY AIR Russian patent published in 2016 - IPC A01C7/04 A01C7/08 

FIELD: process engineering.

SUBSTANCE: invention relates to air operated seeder. Claimed assembly comprises the split manifold with the central inlet, multiple discharge channels extending radially outward relative to the axis and inspection hole arranged opposite the inlet. Said inspection hole is composed by axial cylindrical wall and features the diameter larger than that of discharge hole with discharge channels including the cylindrical bodies. The latter extend radially outward from cylindrical wall and top surface extending from the central inlet to axial cylindrical wall. Said top surface makes multiple flutes separated by ascending ribs extending outward from the inlet to cylindrical wall and have one flute for every discharge channel. Said ribs separate the air-trapped material in its flow from the inlet to discharge channels. Inspection hole is stopped by the cover. Note here that said cover has the inner surface shaped to cone extending toward the inlet. Said cone has bottom wall nearby the ascending ribs to leave spacing between their inner surface and the cone bottom wall from radial inner ring and the inner end of ascending ribs to cylindrical wall.

EFFECT: uniform distribution of air-trapped material.
