[0002] Backfill material mixing devices are used to uniformly blend backfill materials of varying composition. They are widely used in civil engineering, construction, mining, and other fields. These devices typically consist of several key components: a feed system, a mixing chamber, a stirring mechanism, and a discharge port. The core structure is the stirring mechanism, which achieves uniform mixing through powerful agitation, ensuring that the backfill material meets design requirements for strength and stability. An effective backfill material mixing device can improve construction quality, reduce material waste, and ultimately enhance overall project efficiency.
[0003] However, existing backfill material mixing devices often experience blockage during discharge, seriously impacting efficiency. This problem stems primarily from an inadequately designed discharge port, which prevents the mixed backfill material from flowing smoothly, leading to material accumulation and stagnation. High viscosity materials within the mixing chamber, particularly those with a high water content, are particularly prone to blockage, prolonging discharge time and reducing production efficiency.
