The invention relates to a rotary type concrete feed divider for a round-section vertical shaft, and belongs to the technical field of water conservancy and hydropower projects. The feed divider comprises a fixed chute, a receiving hopper, a detachable chute, a concrete discharge hole device and a plurality of vertical columns, wherein the included angle between the fixed chute and the horizontal surface is 30-45 degrees, the receiving hopper is arranged right above a feed end of the fixed chute, the detachable chute is movably connected to the fixed chute, the concrete discharge hole device is arranged at a discharge end of the detachable chute, the vertical columns are used for supporting the fixed chute, and the fixed chute can rotate around the vertical column below the feed end. The feed divider is applied to concrete construction of the round-section vertical shaft, improves the pouring speed of concrete, lowers the safety risk of constructors inside the vertical shaft, lowers the personnel investment and the labor intensity, improves civilized construction, reduces the construction cost and has good economic benefits and social benefits.
