SINGLE-SEED PLANTER Russian patent published in 1996 - IPC

FIELD: agricultural engineering. SUBSTANCE: movable platform of planting member is made in form of one-arm lever. Copying roller, running on guide, moves platform upwards. This force makes conveyor plate secured on chain link turn. Clearances between plates increase which increases loss in seed material. In known design versions rod with seed box occupies working position at a distance from end face wall of seed storage. As a result some seeds are left in chamber. Part of seed material is located out of zone of action of seed box. It is difficult to make seed box of required dimensions in cylindrical rod as length of its front wall is smaller than that of its rear wall. Displacement of seed box to area of rod diameter causes decrease and, consequently, weakening of wedge-shaped projection with L-shaped lip. All this hampers taking seeds one by one. Offered single-seed planter enhances efficiency of seed taking in zone of entry of rod in seed material storage, decreases loss of material, increases accuracy of seed distribution on furrow bottom, increases selectivity of seed box. EFFECT: enlarged operating capabilities. 13 cl, 20 dwg
