SYSTEM OF VOLUMETRIC DOSING WITH SECTIONAL VALVE Russian patent published in 2014 - IPC A01C7/08 A01C15/04 

FIELD: agriculture.

SUBSTANCE: volumetric dosing system for dosing the product in the sowing machine comprises a hopper for product and a distribution system for distribution of the dosed product, having a plurality of individual product channels. The system also has a dose meter drum with a plurality of drum segments aligned along the axis of the drum for dosing the product from the hopper to the distribution system. Along the dose meter drum between the dose meter drum and the distribution system the valves are located, placed in the axial direction. The valves are made with the ability to move between an open position in which the passage of the product is provided from the dose meter drum to the distribution system and a closed position in which the product is prevented from passing from the dose meter drum to the distribution system. The valves have actuators, each of which is mounted with the ability of selective movement of one or more valves from the open to the closed position.

EFFECT: invention enables to reduce downtime of the sowing machines when disconnection of one or several dose meters.
