Particulate metering and mixing system for an agricultural sowing machine

A metering and mixing system of solid particulates for a seed meter in an agricultural equipment for sowing comprising a drive system, wherein the seed meter is mounted under a seed feeder, the seed meter is driven by the drive system that provides rotation to a spinning disc provided with several calibrated orifices through which seeds housed in the disc orifices fall on a given point of the agricultural equipment, and wherein the metering and mixing system of solid particulates comprises a solid particulate feeder that is positioned between the seed feeder and the seed meter, the metering and mixing system further comprising a cylindrical mixing compartment positioned between the seed feeder and the seed meter, the system further comprising a feed receiver mounted under the seed feeder and over the cylindrical mixing compartment, the feed receiver configured for conveying the seeds by gravity from the seed feeder to the cylindrical mixing compartment;

• and wherein the solid particulate feeder comprises a radial solid particulate feeder configured to convey solid particulates to the cylindrical mixing compartment simultaneously with the seeds, where, by means of a propeller, the seeds and solid particulates are mixed together;
• and, after mixing these seeds with the solid particulates, the seeds mixed with the solid particulates are deposited neatly in feeding areas of the seed meter through an outlet window of the cylindrical mixing compartment.
