[0006] As a further aspect of this utility model: the installation position of the air cannon is precisely measured and positioned to ensure that the blowing range of each air cannon can effectively cover the area in the chute where materials are easily stuck, and that the blowing range between each air cannon has no significant overlap or omission.

[0007] As a further aspect of this invention, the device also includes a pressure regulating device for stabilizing the air source pressure between 0.4 and 0.6 MPa, so as to ensure that the air cannon can maintain a stable and effective spraying range under different working conditions.

[0008] As a further embodiment of this invention, the air cannon and the chute are installed via a detachable connector, which facilitates the maintenance, replacement, and adjustment of the air cannon's installation position.
