SEEDER Russian patent published in 2024 - IPC A01C5/06 

FIELD: agricultural engineering.

SUBSTANCE: invention can be used for high-speed continuous sowing of grains, legumes and oilseeds or perennial grasses. The seeder contains a seed hopper mounted on a frame with sowing devices and seed tubes that supply seeds through the hollow rotation axes of spherical cutting disks, and press wheels. The disks are fixed to the frame, facing the soil surface with their concave part and located at an angle to it. In this case, the cutting disks are located at an angle to the direction of movement with the ability to adjust the angle of inclination in the range from 0° up to 90°. In one row the inclination of the disks is the same, but in the next row it is the opposite, and the cutting disks of the second row are shifted in a perpendicular direction relative to the disks of the first row. The seeder is equipped with the cutting disks of the third row, offset relative to the disks of the first and second rows in a perpendicular direction by different steps, covering the soil cultivation zones and eliminating uncultivated gaps. At the same time, behind the third row of cutting disks, underground lifters are installed in the form of vertically mounted spherical disks with alternating teeth and grooves along the cutting edge. The underground lifters are located in pairs above each cutting disk with an opposite angle of attack, to the left and to the right relative to the direction of movement of the seeder.

EFFECT: invention will improve the quality of seed placement over an area by eliminating gaps.
