The gas turbine burner intake control device further includes an intake adjustment mechanism 4 comprising a linear motor 401 mounted on the upper end of the combustion chamber 3. A connecting rod 402 is connected to the power output end of the linear motor 401, and a first bevel gear 403 is fixedly connected to the other end of the connecting rod 402. A rotating rod 405 is rotatably mounted on the upper left side of the combustion chamber 3.
