GEAR-SCREW GEARBOX OF SEEDER Russian patent published in 2023 - IPC A01C7/00 A01C19/00 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to the field of agricultural engineering, in particular to seeders for planting materials with a different seeding rate. A gear-screw gearbox consists of a case, rolling bearings, a drive gear shaft, a driven gear shaft, and cuffs. A gear ratio of the gear-screw gearbox is equal to U=2 at a right angle of inclination of gears of the drive gear shaft β₁=59°36' and a number of gears Z₁ and at a right angle of inclination of gears of the driven gear shaft β₂=30°24' and a number of gears Z₂, an interaxle distance is equal to where m_n is a normal module, mm.

EFFECT: use of the invention allows for reduction in metal consumption and labor intensity of assembly, while simplifying a structure, and in the absence of adjustment of gear engagement.
