SEEDING APPARATUS Russian patent published in 1994 - IPC

FIELD: agricultural engineering. SUBSTANCE: apparatus has casings 1 and permanent length coils 3 mounted inside casing; coils have pins 4. Coils are attached to driving shaft 5 by means of bushings 6 and rivets 7. The coils are shifted relatively axis of the casings in the direction of stroke device made in form of stator 14. Apparatus has back pass spring 15 and anchor 16. Shaft 5 is spring-loaded relatively rest 13, stroke device is mounted in alignment with axis of shaft 5. When seeding mineral fertilizers anchor 16 strokes shaft 5 periodically after application of voltage to stator 14. Coils shake up and release from stuck material. EFFECT: improved efficiency. 2 cl, 1 dwg
