SECTION OF SEEDER-CULTIVATOR Russian patent published in 2012 - IPC A01C7/00 A01B49/06 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery, in particular, to devices for sowing row crops. Section of a seeder-cultivator comprises a suspension, a beam, a gage wheel, holders and an opener. The opener contains a center hoe and a sowing chute. On the beam behind the opener on its lateral sides side brackets are mounted at equal distance from the line of sown seeds. On the side brackets symmetrically with respect to the beam the ridge formers are mounted with an ability of their movement in the horizontal plane at different sides from the line of the sown seeds and fixing in the required position. The ridge formers contain a center hoe, a rack, a bracket with an adjusting plate, an L-shaped bracket with a cavity and a dumping drive made flat. The L-shaped bracket is mounted on the adjusting plate. The dumping drive is mounted on a half-shaft below the edge of the center hoes wings. The lower point of the dumping drives of ridge formers are in the same horizontal plane and located below the edges of the center hoes wings of the opener. The dumping drives of ridge formers are mounted with an ability to adjust the angle of attack symmetrically towards the line of seeds sown at an acute angle to it, and the solution of this angle is directed in the direction of the section movement.

EFFECT: design of the section of a seeder-cultivator enables to increase the quality of planting of row crops and formation of soil ridges above the seeds sown.
