[0002] Premixed mortar refers to various mortar mixtures produced by specialized manufacturers and used in construction projects. It is a new type of building material developed in my country in recent years. It can be divided into ordinary premixed mortar and special mortar according to performance. At present, it is developing rapidly in developed areas such as Shanghai and Changzhou in China. At the same time, many cities are gradually banning on-site mixing of mortar and promoting the use of premixed mortar, which has the advantages of health, environmental protection, stable quality, energy saving and comfort.

[0003] The existing mixing equipment for premixed mortar is equipped with a mixing shaft with mixing blades to mix the mortar, which makes the work efficiency low and easily causes uneven mixing of the mortar, reduces the quality of the premixed mortar, and further affects the pouring effect of the mortar in the later stage.
