Rotary sealing mechanism for fixing center cylinder of stirring barrel

Abstract

The invention discloses a rotary sealing mechanism for fixing a central barrel of a stirring barrel. The central barrel is arranged in the stirring barrel, the central barrel synchronously rotates along with the stirring barrel, and the rotary sealing mechanism comprises a rotary sealing cover; a through hole is formed in the middle of the rotary sealing cover, and the tail end of the central barrel penetrates through the through hole and is located on the rear side of the rotary sealing cover; the rotary sealing mechanism further comprises an outer ring sealing mechanism, the outer ring sealing mechanism is arranged between the outer edge of the rotary sealing cover and the tail end of the stirring barrel, so that the sealing between the rotary sealing cover and the stirring barrel is realized; the rotary sealing mechanism further comprises a pressing device, the pressing device is used for pushing the rotary sealing cover forwards and pressing the outer ring sealing mechanism; and the rotary sealing mechanism further comprises an inner ring sealing mechanism, and the inner ring sealing mechanism is used for realizing sealing between the rotary sealing cover and the central barrel. The rotary sealing mechanism solves the problem of leakage of concrete, prolongs the service life of the sealing device, improves the heat preservation and moisture retention, guarantees the qualityof the concrete, and has the advantages of simple structure and convenience in maintenance.

Description

technical field [0001] The invention relates to a rotary sealing mechanism for a mixer truck. Background technique [0002] When the mixer truck is running in the loading state, the mixing tank will be bumpy, and under the action of external force, the sealing cover and the rotary sealing mechanism at the end of the mixing tank will be deformed, loose and even cracked, which will affect the sealing effect. Bumps and deformations can also cause damage to the rotary sealing mechanism, resulting in problems such as leakage and short service life. [0003] On the other hand, the existing rotary sealing mechanism still has the problems of complicated structure and difficult maintenance. Contents of the invention [0004] The invention proposes a rotary sealing mechanism with a fixed central cylinder of the mixing bucket, the purpose of which is to: (1) reduce the damage of the rotary sealing mechanism during driving; (2) improve the sealing effect; structure.
