Abstract:
A seeding machine comprising:a main transverse support beam; a plurality of planting units mounted to the main transverse support beam, the planting units each comprising a seed meter for metering seed and a furrow opener for forming a planting furrow, the seed meter using air pressure for metering seed; an air pump is pneumatically coupled to an air pressure manifold, the air pressure manifold having a hollow interior with an interior surface and an exterior surface, each of the seed meters of the planting units are pneumatically coupled to the air pressure manifold by air hoses that are attached to individual pneumatic couplers on the air pressure manifold, each individual pneumatic coupler comprises a hollow tube having an inner portion and an outer portion, a radially extending flange separates the inner portion from the outer portion, the radially extending flange having an inner surface that adjoins the inner portion and an outer surface that adjoins the outer portion, the inner portions of the pneumatic couplers extend through apertures in the air pressure manifold, the outer portions of the pneumatic couplers extend outwardly from the air pressure manifold and are coupled to the air hoses for the seed meters, resilient and compressible gaskets are located between the inner surface of the radially extending flanges and the exterior surface of the air pressure manifold, the inner portions of the pneumatic couplers are provided with outwardly extending catches that engage the interior surface of the air pressure manifold locking the pneumatic coupler to the air pressure manifold.
