AI Technical Summary
Existing concrete pouring funnels are prone to segregation when concrete is not mixed evenly, especially when there are large differences in fluidity, making it difficult to effectively buffer and mix.
A concrete pouring funnel comprising a feeding assembly and segmental assemblies was designed. The feeding assembly has a buffer funnel at the bottom, which is a hollow truncated conical structure with spiral mixing blades installed inside. The spiral direction of the mixing blades is opposite to that of the mixing blades inside the adjacent buffer funnels. The segmental assemblies are combined to form a concrete flow channel, and a ceramic-based wear-resistant coating is used to improve wear resistance.
It effectively slows down the falling speed of concrete, avoids the separation of coarse and fine aggregates, enhances the uniformity of concrete, reduces the risk of segregation, and facilitates assembly, installation and disassembly, thus extending its service life.
