Finite element analysis of the load on the mixing blades of a concrete spreading machine

Precast concrete spreader is the core equipment of precast component production line. The spreader prevents the phenomenon of layering and segregation of concrete materials by continuous mixing. When mixing blades mix concrete materials, the force they are subjected to is very complicated. Taking a common worm distributor as an example, the mechanical model is established, the load condition of the blade is analyzed, the blade is transformed into a cantilever beam model, the grid is divided by Ansys software, and the fixed constraints and force conditions are applied. The results show that the equivalent stress of the blade is much less than its yield strength, and the maximum deformation displacement is also less than the allowable deflection. The strength of the concrete material can be improved by changing the shape of the blade and the Angle of arrangement.
