Ball unloading machine for high-temperature gas cooled reactor

The invention relates to the technical field of high-temperature gas cooled reactors, in particular to a ball unloading machine for a high-temperature gas cooled reactor. The top flow cone is fixed in the cavity, and a first conical surface is arranged at the top; gaps are formed between the bottom edge of the first conical surface and the side wall of the cavity; the top of the ball unloading cone is provided with a second conical surface; a ball unloading channel is formed in the position, close to the bottom edge of the second conical surface, of the bottom of the cavity; the fuel balls fall on the first conical surface from the opening and then slide to the second conical surface, the ball unloading cone rotates, and the fuel balls are discharged from the ball unloading channel; vertical pressure generated by the fuel ball is blocked through the top flow cone, and transverse component force is guided to the inner wall of the cavity of the shell and counteracts the transverse component force; therefore, th
