FIELD: agriculture.
SUBSTANCE: system of volumetric dosing is designed to dispense the product in the sowing machine with a hopper for product and distribution system of the dosed product, which has a plurality of individual product channels. The system of dosing comprises a drum of the dispenser, the dispenser housing, a plurality of inserts and actuators. The drum of the dispenser has a plurality of drum segments aligned along its axis, for dispensing the product from the hopper to the distribution system. The housing of the dispenser substantially surrounds the drum of the dispenser and forms an outlet for the passage from it of dosed product. The inserts are arranged in the housing and forms a protrusion through which the product passes to the outlet. In addition, the inserts are removably mounted in the housing for movement between an open position in which the product can pass through the protrusion, and a closed position in which the inserts extend across the passage to block the passing of the product. Each of the actuators is set for selective movement of one or more inserts from the open position to the closed position.
EFFECT: invention enables to reduce the downtime of the machine in case of switching off one or more dispensers.
