[0002] Sandblasting machine belongs to the category of air conveying machinery. It refers to the use of compressed air in a pipeline to transport powdered granular materials from one place to another. In the process of converting kinetic energy into potential energy, the high-speed moving sand particles flush the surface of the object, thereby improving the surface quality of the object. When using the sandblasting machine, the object needs to be placed inside the sandblasting shield for operation, and the outer surface of the object is processed through sealed gloves, and observation is carried out through the transparent window set on the outer surface of the sandblasting shield.

[0003] Since objects will generate large amounts of dust under the action of the sandblasting machine, the dust will accumulate inside the sandblasting shield and may adhere to the inner wall of the transparent window, making it inconvenient for people to observe objects inside the sandblasting shield, reducing the clarity of the transparent window when people use it, and it is more time-consuming and laborious for people to clean the dust on the transparent window, increasing the labor intensity of people when cleaning.

[0004] In view of the above-mentioned related technologies, the inventor believes that the protective cover has the defect that dust may contaminate the observation window. Therefore, a protective device for a sandblasting machine is proposed to solve the above problem.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
