COMBINED SOD SEEDER Russian patent published in 2023 - IPC A01C7/00 

FIELD: agriculture.

SUBSTANCE: combined sod seeder comprises support-drive and rear wheels located on the frame, a seed box with sowing units and their drive, seed ducts, press rollers, a drive gearbox for seeding units, a milling section having operating elements in the form of disks with tillage knives, a mechanism for adjusting the depth of processing, seed guides, casing. Whereas a shield-seal is fixed on the bushing installed on the axle from its rear side inside the casing behind the operating elements under the seed guides. The latter is configured for rotation together with the sleeve around the axis and moving together with the axis in the horizontal direction along the slots in the sidewalls of the casing and is made of a metal plate connected in the lower part with an additional plate. The additional plate is made of a rigid material and has a rounding on the outer part of the plate with a radius R=100 mm facing forward with the convex part in the direction of movement of the seeder. The centre of the rounding circle is above the end of the plate, and the corner of the rounding sector directed forward from it in the direction of the seeder movement is 60°. Whereas it is possible to adjust its position in height with the help of a screw and a groove in the additional plate. A torsion spring is installed on the bushing axis configured for adjusting its force on the upper part from the front side in the direction of movement of the metal plate seeder using a screw device.

EFFECT: invention will provide an increased yield of sown grasses by increasing the uniformity of planting grass seeds in the soil in depth and the formation of a compacted bed at the depth of planting seeds.
