The invention discloses a spiral vibrating type mortar pump. The spiral vibrating type mortar pump comprises two parts: an underframe and a grouting pump which is arranged on the underframe, wherein the grouting pump is composed of a power output mechanism and a pump body; the motor output shaft end in the power output mechanism is connected to an end cam, and the end cam is connected to the pump body through a hinge plate; a truss and a truss track which is fixed on the underframe are arranged at the lower end of the pump body, wherein a reset spring is arranged between the truss and the underframe; the truss and the truss track can move relatively; the truss, the truss track and the end cam form a cam mechanism. The hinge plate is mainly composed of a main hinge plate which is coaxially connected to the end cam and an assistant hinge plate which is coaxially connected to a spiral rod of the pump body; main hinges on the main hinge plate are hinged to assistant hinges on the assistant hinge plate; the assistant hinge plate moves relative to the main hinge plate along the axial direction of the assistant hinge plate; and a profile curve on the end cam is divided into a slow-forward part and a quick-return part. The spiral vibrating type mortar pump disclosed by the invention is compact and simple in structure, the slurry pouring efficiency is relatively high, and the power consumption is small.
