Place an appropriate amount of bearing cover in the shot blasting chamber, and then use the motor to drive the shot blasting chamber to rotate, so that one end of the conveying pipe for conveying the shot blasting extends into the shot blasting chamber. The shot blasting hits the surface of the bearing cover in the shot blasting chamber under the action of pneumatic conveying, and the bearing cover is turned over in the shot blasting chamber driven by the motor, so as to realize shot blasting treatment at different positions of the bearing cover.
[0003] In this method, the bearing cover repeatedly collides with the inside of the shot blasting chamber, causing the shot blasting chamber to be worn after a period of use. Replacing the entire shot blasting chamber will result in a high replacement cost. Therefore, it is necessary to design a bearing cover casting shot blasting equipment that prevents the bearing cover from directly colliding with the inner wall of the shot blasting chamber.
