Abstract

The Connecting Method for the Spiral Blades of Concrete Mixer Truck

Highlights

  • In recent years, the spiral blade of most pear shaped concrete agitators adopts conical logarithmic-style blade, Archimedes-style blade or two-type combined blade

  • For the spiral blade of the concrete mixing tank of concrete mixer truck, in order to satisfy the stirring and discharging performance, the installation angle and helix angle of the blade should be assigned according to their segmentation function

  • In order to solve the defects in the connection gap of spiral blades, we present the MFG whose feasibility is verified by physical production and application

Summary

INTRODUCTION

The spiral blade of most pear shaped concrete agitators adopts conical logarithmic-style blade, Archimedes-style blade or two-type combined blade. As shown, the spiral blade of anterior cone is a spirally oblique conical surface with the constant cross-section, the middle spiral blade is a spirally oblique surface with the constant cross section, and the spiral blade of rear cone is a spirally oblique conical surface with the variable cross section The performance of this tank is better [5], but the parameters calculation in the process of design is more complex. As shown, the spiral blade of anterior cone is a spirally oblique conical surface with the constant cross section, the middle spiral blade is a spirally oblique surface with the constant cross section, and the spiral blade of rear cone is a spirally positive conical surface with the variable cross section The performance of this blade arrangement is not as good as the first one, but the parameters calculation in the design process is acceptable. Stirring is, the better the performance of the discharging is, and vice versa [3, 5]
