AI Technical Summary
Traditional concrete mixing equipment has low production efficiency, excessively long mixing time, and is prone to causing large pieces of material to accumulate at the bottom of the mixing tank, resulting in uneven concrete mixing, cement agglomeration, and aggregate segregation, which shortens the service life of roads and increases maintenance costs.
A two-stage mixing device is adopted, including a primary mixing device and a secondary mixing device. Through a transmission device driven by a servo motor, the material is fully mixed by the meshing of the driving gear, driven gear and bevel gear, combined with the counter-rotation of the mixing shaft and the mixing blades. At the same time, the secondary mixing device agitates the material at the bottom with spiral blades to prevent sedimentation.
It significantly improves concrete mixing efficiency, ensures uniform mixing of materials, reduces mixing time, avoids material sedimentation, extends road service life, and reduces maintenance costs.
