SCARIFIER-INOCULATOR Russian patent published in 2025 - IPC A01C1/06 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to devices for pre-sowing treatment of seeds of leguminous plants, having a shell which is difficult to penetrate for water and air. Scarifier-inoculator comprises a housing and a loading hopper, in the centre of which there is a vertical cylinder and a rotating working element for scarification of seeds. Vertical cylinder is divided into two parts – upper part and lower part. An inoculator with nozzles is installed in the lower part of the housing. On the surface of the rotating working element for seeds scarification there is a ring. At the same time in the rotating working member for seeds scarification there are holes, the area of which is equal to 50…60% of ring inner surface area. Blades are fixed under the ring in the lower part of the rotating working element, the ratio of the outer diameter of which is D₁ to the inner diameter of the lower part of the through vertical cylinder D₂ is 0.85…0.9. Such ratio of diameters provides a gap between blades and lower part of vertical cylinder.

EFFECT: invention will provide an increase in productivity, improved distribution of seeds on the scarifying surface of the working rotating body, exclusion of impact on scarifying surface, improvement of quality and completeness of seeds scarification without their damage, as well as inoculation of seeds before sowing with biological preparations of nodule bacteria.
