Air supply mechanism of combustion engine

The utility model relates to the technical field of combustors, in particular to an air supply mechanism of a combustor, which can be used for simultaneously connecting a plurality of groups of combustors through a main air pipe and a plurality of groups of branch air pipes by using an air blower and adjusting the air quantity entering each group of combustors, thereby realizing the air sharing effect of the plurality of groups of combustors. The use effect is achieved, the occupied area is saved, the energy consumption can be reduced, and the cost is reduced; comprising an air blower, multiple sets of burners and a connecting device, the output end of the air blower communicates with the multiple sets of burners through the connecting device, and the connecting device comprises a terminal, a main air pipe, multiple sets of valve shells, multiple sets of motors, multiple sets of screws, multiple sets of valve plates, multiple sets of screw pipes, an air blowing pipe and a connector; the multiple sets of screw
