Baffle roller anti-swing mechanism for bucket elevator

The invention discloses an anti-swing mechanism for a bucket elevator. The anti-swing mechanism is characterized by comprising guide baffle rollers, a bearing shaft, baffle roller bearings, labyrinth sealing devices, elastic baffle rings for shafts, nuts for fixing the shafts, flat gaskets, a baffle roller support and the like, wherein the guide baffle rollers can freely rotate relative to the bearing shaft by the baffle roller bearings; when a hopper running vertically is subjected to an unbalanced horizontal force on the hopper and excessively swings left and right, the head parts of bolts are contacted with the guide baffle rollers to play a guiding role, so that the normal running of the hopper is ensured; and according to the lift range of the elevator, a pair of or a plurality of pairs of guide baffle rollers are arranged at certain height positions of a bucket elevator shell along an uplink segment and a downlink segment and are used for respectively preventing the hopper of the bucket elevator from excessively swinging left and right during uplink running and downlink running. The guide mechanism is simple in structure and is convenient to manufacture and install, the operating failure rate of equipment is greatly reduced, the maintenance cost of the equipment is reduced, and the guide mechanism is suitable for running guide of the same type of equipment.
