The invention discloses a concrete mixing device for constructional
engineering. The concrete mixing device for constructional
engineering comprises a
barrel body, supporting legs, a sliding supporting groove, feeding hoppers, a sliding frame, a first push rod motor, adjusting partition plates, a rack frame, a transmission part, a power part, a stirring part and a control part, the plurality of vertical supporting legs are fixedly arranged at the bottom of the
barrel body, the horizontal sliding supporting groove is fixedly arranged on the top end of the
barrel body, the two vertical feeding hoppers are fixedly arranged on the top end of the sliding supporting groove, and a vertical opening is formed in a position, below the middle of the sliding supporting groove, of the barrel body in a penetrating mode. According to the concrete mixing device for constructional
engineering, the purpose of adjusting the material mixing proportion can be achieved by adjusting the positions of the two adjusting partition plates in the sliding frame, a first reciprocating stirring
paddle and a second reciprocating stirring
paddle can horizontally move in a stirring barrel in a reciprocating mode through rolling friction between a first rolling wheel and the inner wall of the barrel body and between a second rolling wheel and the inner wall of the barrel body and between a protruding plate and the inner wall of the barrel body. and therefore, materials in the stirring barrel can be stirred more sufficiently.
