AI Technical Summary
When the existing cement-stabilized gravel base paving device stirs materials, the mixing effect of materials near the edge and the middle material is quite different, resulting in uneven mixing and poor practicality.
The three-head block is combined with the stirring parts, and the rotating shaft and rotating rod system is driven by the motor, so that the three-head block drives the stirring parts to rotate. Combined with the meshing structure of the gears and the gear plate, the stirring range is expanded to ensure that the materials are stirred evenly.
It improves the stirring range and uniformity of the material, enhances the practicality of paving, and ensures uniform paving and ironing of the material.
