PNEUMATIC SEED METER WITH ADJUSTABLE DEVICE OF PIECE FEEDING Russian patent published in 2017 - IPC A01C7/04 

FIELD: agriculture.

SUBSTANCE: pneumatic seed meter with the adjustable device of piece feeding comprises the housing with the interior chamber, the disc, the adjustable device of piece seed feeding, and the turning adjustable device. The disc is mounted in the housing with the possibility of rotating around an axis and has a plurality of seed cells spaced radially around the axis to hold the seeds. The piece feeding device comprises two blades adjacent to the seed cells, and at least partially surrounds them for excluding a plurality of seeds from said seed cells. The blades of the piece feeding device are made with the possibility for simultaneously adjusting so that the first blade is progressively moved radially from the axis, and the second blade - radially towards the axis, and that the first blade can also be adjusted radially towards the axis, and a second blade - radially from the axis. The turning adjusting device is operably attached to the piece feeding device in order that the rotating of the turning adjusting device adjusts the distance between the slopes of the first and the second blades due to the movement of at least one of said first or second blades.

EFFECT: improved accuracy of piece seeding.
