AI Technical Summary
The mixing blades of existing road and bridge construction mixing devices have a simple structure, which leads to insufficient mixing of high-viscosity or complex building materials, resulting in local accumulation and affecting construction quality and efficiency.
The stirring blades are supported by a first ball bearing and a second ball bearing. Combined with a stepper motor drive, the stirring blades, mounting ring and extension plate rotate synchronously. The stirring blades, the mounting ring and the extension plate rotate synchronously through the interaction between the baffle plate on the rotating roller and the rolling balls on the inner wall of the mixing tank, so as to achieve all-round stirring and prevent material accumulation and uneven mixing.
It achieves all-round uniform mixing of materials in the mixing tank, prevents local accumulation, improves mixing efficiency and material performance stability, and reduces construction costs.
