Concrete accelerator feeding anti-solidification device

The invention belongs to the technical field of concrete preparation, and particularly relates to a concrete accelerator feeding anti-solidification device which comprises a supporting frame. A plain-end mixing drum is clamped and matched on the support frame; a feed hopper and a discharge hopper are respectively arranged on two sides of the plain-end mixing drum; the top of the plain-end mixing drum is rotationally connected with a top sealing plate; a rotating shaft is fixedly connected to the center of the bottom of the top sealing plate; air is fed through the air inlet pipe, an accelerator is driven by airflow guiding to enter the closed cover body, and then the accelerator is introduced into the plain-end mixing drum through the multiple air inlets, so that the effect of uniformly mixing concrete in the plain-end mixing drum is achieved, and in addition, when the accelerator is fed, sealing plugs at the air inlets are extruded through fed air; the annular cutting edge at the bottom of the sealing plug i
