SEEDING APPARATUS Russian patent published in 2007 - IPC A01C7/04 

FIELD: agricultural engineering, in particular, farm crop drill machines.

SUBSTANCE: seeding apparatus has seed hopper, adjustable shutter and closure equipped with bottom, and grain board pivotally fixed to hopper wall. Grain board is arranged at an angle of at least 27 deg to horizontal plane. Lower end of grain board is oriented toward lower end of bottom. Grain board and bottom are pivotally connected to one another through ejector. Bottom is formed as stepped combed surface. Each comb of said surface has rectangular triangle-shaped cross-section with vertical face facing bottom upper end. Total of angle of inclined faces of comb to bottom and angle of bottom to horizontal plane equals an angle of inclination of grain board to horizontal plane. Closure is fixed to parallelogram hangers for displacement and fixing of hangers pivot joints within slots extending along arcs of circles having permanent radii.

EFFECT: increased efficiency due to uniform feeding of grain, adjustable seeding norms and enhanced reliability in operation of seeding apparatus.
