Seed dispenser and conveyance system for agricultural machinery

Seed dispenser and conveyance system for agricultural machinery, composed of a chassis (10) supporting a circular structural base (20) with lid (22), and an angled vertical base (21) with lid (23), in the upper part of the base (20), containing a seed box (30), a vacuum turbine (40) and a cutting disk (50), with the system activated by a bar (223) and gear (222) which rotate, in a clockwise movement, the selection disk (V1) with gaps (V2), movement transmission dents (V3) and wavy external edge (V4);

• the selection disk (V1) transmits the movement to the hollowed gear (B1), which moves in a counter-clockwise movement with gaps (B2), gear (B3), movement gear (B4) and synchronism wavy external edge (B5) with the selection disk (V1);
• the hollowed gear (B1) transmits the movement to the hollowed gear (C1), which moves in a clockwise movement, with gaps (C2), gear (C3) and movement transmission gear (C4);
• the hollowed gear (C1) transmits the movement to the hollowed gear (D1), which moves in a counter-clockwise movement, with gaps (D2), gear (D3) and movement transmission gear (D4);
• the hollowed gear (D1) transmits the movement to the hollowed gear (El), which moves in a clockwise movement, with gaps (E2) and movement gear (E3), conveying the seeds (60) to the seeding ramp (211);
• the vacuum pump (40) with pipes (41) attached to the fit hole (204) of the circular structural base (20) generates vacuum suction inside the base (20) when attached to the lid, with the vacuum generated between a pair of rubbers (201), placing the seeds in the gaps (V2) of the disk (V1).
