FIELD: agriculture.

SUBSTANCE: ploughshare for different-level sowing of seeds and fertilizers includes a stilt, a duckfoot shovel, a seed tube. Knife is installed along longitudinal axis of symmetry of duckfoot shovel in its front part before stilt, front edge of which is sharpened. Stilt is made hollow and is installed along the longitudinal axis of symmetry of the duckfoot shovel. Between the duckfoot shovel wings parallel to the duckfoot shovel wings cutting edges the isosceles triangle plate is installed, which vertex is directed towards direction of movement of duckfoot shovel and sides is rigidly fixed with inner sides of duckfoot shovel wings. In the plate base in the form of isosceles triangle horizontal slot is made. Seed duct is installed vertically along the axis of symmetry of the duckfoot shovel above the horizontal slot of the plate, and from the rear side of the lower part of the seed duct there is a vertical groove. On the extension of vertical axis of symmetry of the stilt and coaxially to the stilt there is a soil-bowl in the form of a tetrahedron and with a sharp face is directed towards direction of movement of the opener. In the lower part of the pier head an outlet hole is made and directed towards the side opposite to direction of the ploughshare movement. Leveler arranged in the form of an isosceles trapezoid is installed under the seed drill. Trapezoid is rigidly attached to the lower part of the plate in the form of an isosceles triangle and to the inner sides of the duckfoot shovel wings. Lower part of leveler is diverted towards the side opposite to direction of ploughshare movement.

EFFECT: higher quality of sowing.
