Wet-mixed mortar preparation device

The utility model belongs to the technical field of mortar mixers, and particularly relates to a wet-mixed mortar preparation device. Comprising an outer shell, two filtering mechanisms and a stirring mechanism, and the filtering mechanisms are arranged at the top in the outer shell; the stirring mechanism is arranged at the inner bottom of the outer shell and comprises a main shaft penetrating through the outer shell from top to bottom and two first spiral blades abutting against the inner circumferential wall of the outer shell, and the first spiral blades are symmetrically connected to the main shaft through stirring arms. The filtering mechanism comprises a filtering hopper and a cam mechanism abutting against the bottom of the filtering hopper. The filtering hopper is connected to the inner top of the inner shell through a spring arranged at the top. The filtering hopper vibrates through rotation of the cam mechanism, filtering of large particles left in fine aggregate is accelerated, the filtered fine a
