SYSTEM OF VOLUMETRIC DOSING WITH SECTIONAL MECHANISM OF OVERLAPPING WITH CLUTCH Russian patent published in 2015 - IPC A01C7/08 

FIELD: agriculture.

SUBSTANCE: invention relates to a system of volumetric dosing of the product and can be used in sowing machine having a product tank and a distribution system for distributing a dosed product having a plurality of separate product channels. The distribution system for distributing the dosed product comprises a drum of dispenser, a common drive shaft and a clutch mechanism. The drum of the dispenser consists of a plurality of drum segments aligned along the axis of the drum for dispensing the product from the hopper to the distribution system. The common drive shaft passes through the drum segments for driving them in rotation. The clutch mechanism is located radially inside at least one drum segment between at least one drum segment and the drive shaft for selective connecting in driving manner and disconnecting in driving manner of at least one drum segment with the drive shaft and from it.

EFFECT: invention enables to reduce the delay time from the time of overlapping of a certain segment of the dispenser until the termination of the flow of seeds into the soil and seed damage by the drum.
