NEW METERING DEVICE FOR PNEUMATIC SEEDING MACHINE

Various pneumatic systems of existing pneumatic devices, row-crop seeders, operating both in vacuum and at overpressure of the air flow, have been analyzed. Such systems are used for seeding seeds in different ways, for example, dotted and combined. As a result of the analysis, it was found that in all cases, for each method of sowing seeds, a separate metering device is required, therefore, our task was to create such a design of the seeding device, in which it is possible to sow both in a dotted manner and combined, without changing their constituent elements. The implementation of this goal is given in this work.
