Abstract:
In an air seeding implement for planting agricultural products into the ground, said air seeding implement having a wheeled frame, a storage tank supported on said frame to contain a supply of agricultural seeds to be planted into the ground; a fan mounted on said frame and being operable to create a flow of air; air flow tubes corresponding to said storage tank and being operably associated with said fan to receive said flow of air, said air flow tubes having a diameter; a metering mechanism to distribute the agricultural seeds into said air flow tubes to be carried by the air flow therein for delivery to a remote location for insertion into the ground; and a supply of seed treatment material, the improvement comprising:a generally linear seed treating unit connected with at least one of said air flow tubes downstream from said metering mechanism and connected to said supply of seed treatment material to coat said agricultural seeds with said seed treatment material as said agricultural seeds are conveyed generally linearly within said air flow tubes, said seed treating unit including:a generally cylindrical housing having a diameter substantially equal to the diameter of said air flow tubes and defining an in-line flow path along an axis of said housing, said at least one air flow tube being connected to opposing ends of said housing along said axis;a baffle within said housing to direct said agricultural seeds within said air flow radially outwardly toward said housing in a spiral flow path along said axis; andan injection port on said housing connected radially relative to said axis to inject said supply of seed treatment material into said housing at an injection point for mixing within said air flow and coating said agricultural seeds.
