[0002] During the production and maintenance of metal workpieces, surface rust removal is a key process. Sandblasting rust removal is a commonly used and efficient rust removal method at present. It removes rust, scale and other impurities by spraying sand grains at high speed to impact the metal surface, so as to obtain good surface cleanliness and roughness, and provide a high-quality surface basis for subsequent processes such as painting and welding.

[0003] After retrieval, it is found that a typical prior art is a sandblasting room with the publication number CN212311769U, which includes a room body. A recovery chamber is separated by a grille plate on the lower side of the room body. Symmetrically arranged left and right feeding groups are respectively provided on both sides of the recovery chamber. A screw conveyor is arranged between the left and right feeding groups. The left and right feeding groups are both inclined downward towards the screw conveyor. The left and right feeding groups are both composed of a plurality of feeding conveyor belts arranged in a row. A dust removal channel and an air inlet channel are respectively provided on the room body. A sandblaster is provided on the grille plate.

[0004] To sum up, during sandblasting operations in existing sandblasting rooms, it is usually necessary to manually operate a spray gun to sandblast workpieces. This not only has a high labor intensity, but also it is difficult to ensure the consistency of manual operations, easily resulting in uneven rust removal effects on the surfaces of workpieces, affecting the quality of subsequent processing.
