SEEDING UNIT Russian patent published in 1999 - IPC

FIELD: agricultural engineering. SUBSTANCE: seeding unit has housing, two disks mounted in opposed relation within housing at opposite sides at an angle to vertical plane bisecting seeding window. Disks converge at their lower parts and are mounted on drive shafts axially aligned with disks. Inclined chute narrowing toward its lower end is fixed above seeding window between disks. Angle between horizontal plane and line drawn through window and chute lower edges is below angle of repose of seeding material. While mass of seeding material is delivered through charging window and is conveyed along chute to right-hand lower sector of disks, it is imparted wedge shape in diametrical section of disks. During uniform rotation of shafts in common direction, seeding material enclosed between disks is uniformly fed to seeding window. Chute prevents seeding material from involuntary spilling through window. EFFECT: increased efficiency by uniform seeding, simplified construction and enhanced reliability in operation. 5 cl, 3 dwg
