FIELD: physics.
SUBSTANCE: present invention relates to a double dosing device for dispensing seeds, grains or other loose materials driven by a direct drive. More specifically, the present invention relates to a double seed dosing device for seeders driven by one electric motor of annular type with a hollow shaft with holes located coaxially between two housings with two dosing discs. At the same time, the double device contains two chambers or seed tanks loaded with seeds of different types, and is made with possibility of selective sowing of seeds from one or another container. At that, selection of seed type is instantaneous and does not require either equipment shutdown or manual mechanical adjustments.
EFFECT: invention will make it possible to increase overall efficiency due to simplification of design and to increase service life of the double device.
