Multi-cylinder conical horizontal shaft bushing

The invention relates to the technical field of shaft bushings, in particular to a multi-cylinder conical horizontal shaft bushing which comprises a first fixed shaft bushing, a second fixed shaft bushing, a roller replacement cylinder, a circular motion connecting rod, a continuous pressure applying type roller assembly and a roller rapid replacement assembly. Round mounting grooves are formed in the opposite sides of the first fixing shaft bushing and the second fixing shaft bushing, annular driving structures are arranged in the round mounting grooves, the circular motion connecting rods are mounted in the annular driving structures, and the two ends of the roller replacing cylinder are connected with the two circular motion connecting rods correspondingly. Strip-shaped mounting grooves are formed in the first fixed shaft bushing and the second fixed shaft bushing; the continuous pressure applying type roller assembly is used for protecting the horizontal shaft of the cone crusher, the extrusion limiting e
