SOWING SECTION FOR VARIABLE-DEPTH CLUMP PLANTING OF TILLED CROPS SEEDS Russian patent published in 2020 - IPC A01C7/18 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to seeders for variable-depth clump planting of tilled crops seeds. Seeder section for variable-depth clump planting of tilled crops seeds consists of frame, hinged-lever suspension, pneumatic seeding device, seed box, sowing disk, ploughshare, coverers, roller, flat, left, right and main compartments of the ploughshare. Under the pneumatic sowing device there is a distributing device in the form of a roller with three cells, the axes of which are located at angle of 45° relative to each other. Roller is fixed on the drive shaft, which provides synchronous rotation of the sowing disk due to chain transmission. Profile of the first and third cells has curvilinear surface, which connects middle part of roller with right and left parts of roller accordingly. Second cell is located in the middle part of the roller and its profile is cone-shaped. At the same time left and right parts of roller are separated from its middle part by means of two grooves, in which there enter are limiting plates having cutout, sizes of which correspond to sizes of first and third cells.

EFFECT: invention will make it possible to increase accuracy of seed distribution in compartments of the ploughshare.
