Building concrete additive ingredient mixing equipment

The invention discloses building concrete additive ingredient mixing equipment, and relates to the technical field of concrete additive production equipment, and the building concrete additive ingredient mixing equipment comprises a mixing tank, a material guide shell, a material storage barrel, an intermittent plugging assembly, a scattering assembly, a multidirectional stirring assembly and a pushing assembly. By arranging the intermittent plugging assembly and the centrifugal barrel, when the centrifugal barrel rotates, a reciprocating lead screw is driven to rotate, a straight gear ring drives a first straight gear to drive the reciprocating lead screw to rotate, and therefore a sliding block is driven to drive a first connecting block and a rectangular sleeve to reciprocate up and down; a sealing baffle is driven by a first connecting block to move up and down in a reciprocating manner, a discharge port of a centrifugal barrel is intermittently opened, and various premixed ingredients in the centrifugal
