PNEUMATIC SOWING MECHANISM Russian patent published in 1995 - IPC

FIELD: agricultural engineering. SUBSTANCE: mechanism has seed and vacuum chambers is housing, seed disk with suck-holes and excess seed flicker in from of curvilinear plate. Flicker attachment member is made in form of rod spring-loaded relative to housing Geometrical axis of rod is directed along disk radius. One end of rod is rigidly connected with curvilinear plate and other end is located in hole of housing and is connected with housing by kinematic pair. Working surface of curvilinear plate is provided with coating whose friction coefficient is less than 0.3. EFFECT: enlarged operating capabilities. 1 dwg
