DEVICE FOR DOTTED-HILL SOWING OF SOYA SEEDS Russian patent published in 2020 - IPC A01C7/04 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, particularly, to precision soya bean seeding devices. Device for dotted-hill sowing of soya seeds contains cylindrical sowing disk with cylindrical cells with chamfers shifted by preset angle in adjacent rows. Cells are arranged with uniform circumferential pitch with preset number of intermittent groups. Trapezoidal grooves are arranged above the cells. Cylindrical sowing disk is installed in the housing under the hopper. Above the cylindrical sowing disk there is a cylindrical roller-reflector with a band, the side surface of which is made in the form of trapezoidal ledges displaced to the specified angle in the next rows. Latter are arranged in a uniform circumferential pitch similar to the sowing disk in several pieces in discontinuous groups. Protrusions are made with specified clearance above trapezoidal grooves of sowing disk. Trapezoidal guide tray is installed on the lower edge of the body at the angle of the natural slope of seeds.

EFFECT: use of the invention will make it possible to increase filling of cells with seeds, to eliminate their damaging and thereby to increase uniformity of soya sowing.
