The worm gear (204) in the power component (2) is connected and fixed to the barrel (106) by a keyway connection and a fixed block bolt connection. The stepping motor (201) in the power component (2) provides power to the worm gear (204) and the worm, (203) to make the barrel (106) rotate, thereby changing the inclination direction of the end of the barrel (106) that passes through the wall (3) and has an inclination, thereby achieving a multi-directional coal flow-aiding effect.

When the barrel 106 drives the rotating seal 108 to rotate, the rubber stopper 1081 and the circular inclined spring 1083 are compressed to undergo a certain elastic deformation. The circular inclined spring 1083 is used to limit the deformation of the rubber stopper 1081 and the reaction force generated when it is compressed to make the sealing between the rubber stopper 1081 and the barrel 106 better. There is sliding friction between the rubber stopper 1081 and the connecting steel pipe 105.
[0030] In summary, the embodiment of this invention provides an air cannon flow-aiding device with adjustable injection angle. When the air cannon 101 of this device is working, the rotating seal 108 can effectively ensure the sealing between the connecting steel pipe 105 and the barrel 106. The transmission mechanism composed of the worm gear 204 and the worm 203 used in the power assembly 2 can achieve self-locking when it stops working, and will not cause reverse rotation. The power assembly 2 provides the barrel 106 with self-rotation power, which can achieve a multi-angle coal flow-aiding effect with the end of the barrel 106 with an angle on the inner side of the wall 3 of the coal bunker.
