Chute alpha angle tilting mechanism of blast furnace bell-less distributor

The utility model discloses an angle alpha tilting mechanism with a chute for a bell-less material distributor in a blast furnace, which comprises a supporting ring, a slewing bearing, an upper transmission system for driving the supporting ring to vertically move, a rotating sleeve, a chute suspending device, a chute and a lower transmission mechanism converted from vertical rectilinear motion into chute titling through the supporting ring; and the lower transmission mechanism is a planet wheel straight line mechanism The planet wheel straight line mechanism is fixed on the rotating sleeve and is connected with a moving ring of the slewing bearing through a drive rod; the drive rod is arranged on the moving ring of the slewing bearing; the chute suspending device comprises trunnions arranged on the two sides of the rotating sleeve and a chute suspending frame connected with the trunnions; and the planet wheel straight line mechanism is connected with the chute suspending frame through the trunnions The angle alpha tilting mechanism has the beneficial effects that the angle alpha tilting mechanism is the planet wheel straight line mechanism, the drive rod always carries out rectilinear motion under the drive of the supporting ring in the changing process of an angle alpha, the supporting ring has no lateral force, a track and a roller are eliminated, the overall structure is simplified, and the precision of equipment can be ensured, and the long service life is realized
