A pipe for conveying concrete

Abstract

The utility model discloses a pipeline for conveying concrete, including the straight pipe section and the elbow section of intercommunication, and the elbow section is rotatable along the pipeline axial direction and is equipped with first dredging axle, second dredging axle and third dredging axle, and all are fixedly connected with the helical blade of same direction, and the one end outside of elbow section is equipped with the drive motor, and the rotary output of drive motor is fixedly connected with the connecting shaft, and the tail end of connecting shaft is fixedly connected with first bevel gear, one end of first dredging axle is fixedly connected with the second bevel gear of first bevel gear interlock, and the other end is fixedly connected with third bevel gear, and the both ends of second dredging axle and third dredging axle are equipped with third bevel gear. The design first dredging axle, second dredging axle and third dredging axle are driven under the drive of drive motor, and the helical blade of its surface same direction sets up the concrete axial movement of helical pushing in the elbow section, and dredges the concrete of elbow section, prevents the congestion of happening in elbow section.
