A concrete mixing-and-transport truck with rotary sealed feeding/discharging opening of stirring cylinder

摘要

A concrete mixing-and-transport truck is provided, which comprises a stirring cylinder with a rotary sealed feeding/discharging opening. A annularity sealed cavity is formed between the outer wall of a rotary inner cylinder (15), the inner wall of a fixed outer cylinder (6-2), the back end face of a rotary flange support base (6-1) and the front end face of a sealing end cover (7). At least one sealing belt (13) is set in the annularity rotary sealed cavity. The back end face of the last end sealing belt (13) is contacted tightly with the front end face of the sealing end cover (7). The stirring cylinder and the feeding/discharging opening are connected rotationally by reliable rotary sealing so as to make the stirring cylinder keep rotating when feeding, and reduce the centre of gravity of the carrier vehicle. The truck improves driving safety, eliminates concrete demixing problem and improves the quality of concrete and architecture quality.
