[0002] Shot blasting machine refers to a casting equipment that uses high-speed projectiles thrown by a shot blaster to clean or strengthen the surface of castings. It is a processing technology that uses a shot blaster to throw steel sand and steel shots at high speed and impact on the surface of material objects.

[0003] In the existing technology, there are many different types of shot blasting machines. For example, according to the different structures of the casting carrier, they are divided into drum type, chain plate type, turntable type, trolley type, squirrel cage type and hanging type shot blasting machines, etc. Turntable type, trolley type and hanging type shot blasting machines are used to clean large and medium-sized castings. They are usually equipped with a fixed shot blasting chamber, and the cleaned castings rotate or move in the shot blasting chamber. The shot blasting chamber is generally equipped with several shot blasters, which are installed in different positions and projectiles from different directions to improve the cleaning efficiency and cleaning quality of the shot blasting machine. However, at present, when the turntable or trolley type shot blasting machine is performing cleaning work, the workpiece to be cleaned is placed on the turntable, and there is often a dead corner for workpiece cleaning (the bottom of the workpiece to be cleaned). Therefore, it is necessary to suspend the shot blasting during the cleaning process, turn the workpiece over, and then operate the shot blasting, which makes the cleaning operation process complicated, the production efficiency is low, and the labor intensity is increased.
