Pumpable concrete producing machine - has auger-type coaxial mixer and pump driven by common source and auger conveyor above

摘要

The machine produces pumpable concrete on a building site, having a mixer followed by an auger-type pump. Coaxial to the pump (14) is an auger-type mixer (130), whose shaft rotates with that of the pump and is driven from the same source. Above and parallel to unit formed by the mixer and pump is an auger conveyor (9) working in the opposite direction, and with a shaft (11) connecting its outlet to the mixer inlet. The conveyor auger comprises in succession transport (9a), metering (9b) and initial-mixing (9c) sections, while a pipe (8) delivers water between the latter two. USE/ADVANTAGE - Compact, reliable, and can deliver concrete continuously.
