SEEDING UNIT OF GRAIN DRILLS Russian patent published in 2015 - IPC A01C7/00 A01C5/06 

FIELD: agriculture.

SUBSTANCE: seeding unit comprises a device for furrow breakdown made in the form of at least one disc of coulter, a device for feeding the seeds into the furrow, a device for feeding the fertilizer into the furrow, a device for closing the furrow, a device for embedding the seeds, and a device for controlling the sowing depth. The device for controlling the sowing depth is made in the form of at least one wheel of embedding control. The wheel of control has an embedding control mechanism located on the balancing beam. The pivotally connected end of the embedding control mechanism acts on a lever attached to the arm of the corresponding wheel of embedding control to ensure the free and independent movement of the said wheel. The arm of the wheel of embedding control is attached to the movable plate of the corresponding hinge mechanism with providing the possibility of rocking movement of the said wheel and the said movable plate relative to the disc in its open position. The arm is also attached with providing the possibility of fixing the said wheel, preventing rocking movement relative to the disc in its closed position. The other plate of the hinge mechanism is attached to the balancing beam.

EFFECT: invention enables to simplify the process of removal of crop residues, dust, damp soil, to increase cleaning efficiency and to speed up the cleaning process, reducing the machine downtime.
