Anti-abrasion device for rotating connector of external conveying cylinder

The utility model discloses an anti-abrasion device for a rotating connector of an external conveying cylinder. The anti-abrasion device comprises a rubber elbow pipe, a rotating connector stirring rod device and an elastic support with adjustable height, wherein the rubber elbow pipe is arranged between an oil-conveying hard pipe of the external conveying cylinder and the rotating connector; the rotating connector stirring rod device is used for transferring a torque force and driving the rotating connector to rotate; and the elastic support is arranged at the bottom of the rotating connector. The beating caused by the non-concentricity of the rotating connector and a flange of the external conveying cylinder at the rotating moment of the external conveying cylinder is effectively compensated by the rubber connector of the anti-abrasion device provided by the utility model, so that the abrasion of the rotating connector is reduced; the torque force at the rubber connector is effectively endured by the rotati
