Ring-shaped chute material distributor of cylindrical silo

The invention discloses a ring-shaped chute material distributor of a cylindrical silo. The ring-shaped chute material distributor comprises a middle straight-section fixed chute, lower end of which is fixed on the ground, wherein a middle straight-section movable chute is connected at the upper end of the middle straight-section fixed chute through a swing mechanism; a charge section chute is connected at the upper end of the middle straight-section movable chute; a rotary material-receiving forked-section chute is arranged on the side surface of the charge section chute; the charge section chute and the rotary material-receiving forked-section chute form an inverted-Y-shaped structure; an inclined-section chute comprises an electro-hydraulic bulkhead gate, a middle inclined-section chute and an unloading turn-section chute which are sequentially connected with the lower end of the rotary material-receiving forked-section chute; a bent-angle outlet which is perpendicular to the ground is formed in the lower end of the unloading turn-section chute; a ring-shaped rail is arranged, along a ring-shaped coal unloading ditch, at the lower end of the a bent-angle outlet of the unloading turn-section chute; and a travelling mechanism is arranged on the ring-shaped rail. The equipment swing mechanism adopts a hollow type swing mechanism, so that materials can be unloaded into the cylindrical silo through a central position, thereby further improving volume fraction of the cylindrical silo. The ring-shaped chute material distributor is simple in structure, good in working stability, low in fault rate and long in maintenance period.
