An angle-adjustable axial flow fan blade

Abstract

The present disclosure relates to the technical field of axial flow fan, and provides an angle-adjustable axial flow fan blade, which comprises a rotating blade, a support leg fixedly connected to the circumferential surface of a shell, a sleeve fixedly connected to the inner side of the shell, a drive machine fixedly connected to the inner side of the sleeve, an output shaft of the drive machine, a rotating shaft fixedly connected to one end of the output shaft, the rotating blade fixedly connected to the other end of the rotating shaft, an angle adjusting device arranged on the inner side of the shell, one end of a fixed rod fixedly connected to the inner side of the shell, a connecting shaft rotatably connected to the other end of the fixed rod, a connecting rod rotatably connected to the circumferential surface of the connecting shaft, one end of the connecting rod fixedly connected to the circumferential surface of the sleeve, a drive shaft penetrating through the circumferential surface of the shell, and a main gear fixedly connected to the circumferential surface of the drive shaft. Through the above technical scheme, the problem of adjusting the axial flow fan blade in the prior art is solved.
