TILLING-AND-SEEDING MACHINE Russian patent published in 2004 - IPC

FIELD: agricultural engineering. SUBSTANCE: invention relates to machines for simultaneous tilling and seeding. It contains tilling section, seeding sections of colter boots, working members for cleaning from trash, closers and covering rollers. Tilling sections are furnished with depth stabilizers in form of double- prong fork to provide stability of seeding to preset depth and seed covering. Prongs of double-prong forks are connected by axles on which wavy disks are mounted. Forks are located in longitudinally vertical plane with tilting forward and provided with two working surfaces arranged at angle relative to each other decreasing in size to end of prong. Wavy disks are provided with flanges. Prongs and axles of stabilizers are connected for turning and fixing in longitudinal vertical plane. Such design of machine makes it possible to provide penetration of wavy disks to preset depth in process of band treatment in trace of future drill rows without treatment of soil over entire operating width and maintaining the width in process of seeding without exceeding tolerable deviation from preset of seed embedding. EFFECT: provision of stable seeding to required depth and embedding of seeds. 3 cl, 5 dwg
