In order to solve the technical problems, the technical scheme adopted by the invention is as follows: comprises a cylinder body; an installation frame is arranged on one side of the outer part of the cylinder body; the mounting frame and the barrel are welded; an actuator is arranged outside the mounting rack; the actuator is connected with the mounting frame through bolts; an outer barrel is arranged at one end of the barrel in the axial direction; the outer cylinder and the inner wall of the cylinder are welded; an adjusting mechanism is arranged inside the barrel body on one side of the outer barrel.
Further optimizing the technical scheme, the adjusting mechanism comprises a transmission shaft, an upper bevel gear, a lower bevel gear, a connecting shaft and an inner cylinder; the transmission shaft penetrates through the cylinder body and is then in pin joint with the actuator; the upper bevel gear is pinned at one end of the transmission shaft; a connecting shaft is welded in the middle of the upper part of the inner cylinder; the connecting shaft is connected with the outer cylinder through a bearing seat.
Further optimizing the technical scheme, one end of the connecting shaft is connected with a lower bevel gear in a pin joint mode; and the lower bevel gear is in meshed connection with the upper bevel gear.
Further optimizing the technical scheme, the upper parts of the inner cylinder and the outer cylinder are symmetrically provided with vent holes; the inner cylinder and the outer cylinder are in a boss shape.
Compared with the prior art, the invention has the following advantages: 1. an outer barrel is arranged at one end in the axial direction in the barrel body, and is sleeved with the inner barrel, and then the inner barrel and the outer barrel rotate coaxially, so that the air inlet amount at the vent can be effectively adjusted; 2. the lower bevel gear is meshed with the upper bevel gear, and the accuracy of adjusting the rotating angle between the inner cylinder and the outer cylinder is improved in a gear meshing connection mode.
