OPENER FOR SUBSOIL BROADCAST SOWING OF SEEDS Russian patent published in 2022 - IPC A01C7/20 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, in particular to the working bodies of seeders for subsoil scattered sowing of seeds to the bottom of the furrow in the sub-plow space. The coulter consists of a stand with a mounting bracket, a duckfoot share mounted at the end of the stand, a holder for the seed and seed tube, a seed distributor, zigzag-shaped compactor elements, offset by mutually protruding parts towards each other by an amount of l=50 mm along the direction of movement of the unit to exclude possible unloading land. The elements of the seal are installed at an angle α=35° relative to the motion vector and are rigidly attached to the axis, the ends of which protrude through the holes in the ribs of the duckfoot paw to its outer surface. At the ends of the axle, pressure rods are installed with an inclination in two planes at an angle to the horizontal α=35° and at an angle to the motion vector α=35°. The rods are directed towards the center of the sowing strip in the direction opposite to the direction of movement of the unit. The movement of the compactor elements at the level b = 10-12 mm from the surface of the seed bed is limited by an emphasis. To return the descending soil from the edges of the duckfoot to the center of the seeding strip, flaps are installed at the end of the ribs at an angle γ=20°, directed to the center of the seeding strip in the direction opposite to the vector of movement of the unit.

EFFECT: use of the invention will improve the quality of the technological process of scattered sowing of seeds on the seedbed.
