Improved sintering machine platform grid section

The utility model relates to the technical field of sintering machine platform grate bars, and discloses an improved sintering machine platform grate bar which comprises a grate bar body, an optimization mechanism is arranged at the bottom of the grate bar body, and a mounting mechanism is arranged in the optimization mechanism. According to the improved sintering machine platform grate bar, through the arrangement of the optimization mechanism, the round bottom block with the trapezoid section of the grate bar main body is changed into the round section, after the round bottom block is changed into the round section, airflow can smoothly pass through a mixture layer, the problem that dead angles are generated when the airflow passes through the original trapezoid section is solved, airflow resistance is reduced, and the service life of the sintering machine platform grate bar is prolonged. According to the original design, supporting plates on the two sides of the bottom of a grate body are square and are fi
