1. A chute tube device for transferring particles, comprising:
a charging chute tube having a charge inlet;
a discharging chute tube located at a position vertically lower and horizontally different than the charging chute tube and connected to at least one of a screen, a conveyor, or a divider; and
an intermediate chute tube which is connected to the charging chute tube and the discharging chute tube in a slanting direction;
wherein the intermediate chute tube comprises a groove without steps formed by a combination of a first inclined surface and a second inclined surface, and
the groove is of a cross-sectional shape corresponding to two adjacent sides of a triangle, and one or more flow rectifying plates are arranged on the first inclined surface and the second inclined surface of the intermediate chute tube for narrowing the width of the groove to facilitate the particles flow centrally of the groove.
