Description

Casting sand material loading transmission device Technical Field The utility model relates to the technical field of casting, in particular to a casting sand feeding and conveying device. Background In the casting process, the shape can be shaped by using a die, and casting sand, electric melting ceramsite sand, namely, baozite sand, casting sand and bauxite ceramsite sand are poured in the die. The electric smelting ceramsite sand is prepared by taking high-quality bauxite as a raw material and adopting ceramsite sand processes such as calcination, electric smelting, granulation, screening and the like. The Baozhu sand is a substitute of quartz sand, overcomes the defects of large expansion coefficient, low casting precision, serious sand sticking and the like of the quartz sand, improves the quality of the casting, and can carry the casting sand by using the feeding and conveying device for casting conveniently. Casting sand material loading transmission device among the prior art, when in actual use, lack the function of screening the casting sand that gets into the conveyer, this just leads to the casting sand size that gets into the conveyer different, thereby the casting sand of equidimension stacks up and appears the gap together easily and leads to influencing the casting quality to the foundry goods, so we propose a casting sand material loading transmission device for solve the problem that above-mentioned proposes.
