[0002] Shot blasting machine is a mechanical device that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of the workpiece. The shot blasting machine can simultaneously remove sand, core and clean the castings. It can also be used for surface treatment of forgings, aluminum-magnesium alloy parts, sheet metal welded parts, etc. In some areas, it is also called sandblasting machine or sandblasting machine.

[0003] The existing shot blasting machine adopts chain track hoisting to the shot blasting machine for sand dropping treatment, or adopts material rack to put into the shot blasting machine for sand dropping treatment. These two methods have their own advantages and disadvantages. Chain track hoisting and sand dropping are not suitable for multiple pieces to drop sand at the same time. The main reason is that only shot blasting can be carried out on both sides through movement, and the small rotation angle leads to more dead angles, which is suitable for single-room polishing treatment; while the material rack is put into the shot blasting machine, this kind of material discharge switching speed is slow, and continuous shot blasting cannot be achieved. In addition, the shot blasting machine is designed to be sealed, and there is a lot of dust after opening. Workers will feel uncomfortable when pushing the material rack into it.
