The shot blasting machine can simultaneously remove sand, remove cores and clean castings. In some areas, it is also verbally called a sandblasting machine or a sandblasting machine. The shot blasting machine is a processing technology that uses a shot blasting machine to throw steel sand and steel shots at high speed onto the surface of material objects. Compared with other surface treatment technologies, it is faster and more effective, and can be used for the casting process after partial retention or stamping.

[0003] The prior art, such as the angle-adjustable shot blasting machine disclosed in patent publication number CN218837383U, includes a frame having a working chamber and an opening, the working chamber being connected to the opening, a transport member being movable and arranged at the opening, and after the transport member moves, the transport member entering the working chamber, the shot blasting machine being arranged on the frame and located in the working chamber, an angle adjustment assembly being arranged on the shot blasting machine nozzle, the angle adjustment assembly including a nozzle 1 being rotatably arranged on the shot blasting machine nozzle, a nozzle 2 being rotatably arranged on the nozzle 1, the rotation axis of the nozzle 1 intersecting with the rotation axis of the nozzle 2, a jet channel being formed between the nozzle 1 and the nozzle 2, and the jet channel being connected to the working chamber. The above technical solution solves the problem in the prior art that the angle of high-speed projectiles thrown from the chamber of the hanging shot blasting machine cannot be adjusted, resulting in some parts of workpieces with special shapes being unable to be processed.
