The left end of the first fixed frame 405 located at the left end and the front end of the first fixed frame 405 located at the right end are fixedly connected to the fourth motor 402, and the output shaft end of the fourth motor 402 is fixedly connected to the first shot blasting impeller 407. The first fixed frame 405 and the second fixed frame 403 are fixedly connected through the feed hopper 401, and the feed hopper 401 is communicated with the first fixed frame 405 and the second fixed frame 403.

A second discharge hole 410 is opened on the lower end surface of the second fixed frame 403, and the second discharge hole 410 penetrates the shot blasting frame 408 downward.

[0021] During operation, the projectiles can enter the first fixed frame 405 and the second fixed frame 403 through the feed hopper 401, and the operation of the fourth motor 2 404 will drive the second shot blasting impeller 406 to rotate, and the operation of the fourth motor 1 402 will drive the first shot blasting impeller 407 to rotate.

[0030] Working principle:

[0031] The feed hopper 401 is externally connected to a feeding device of a shot blasting machine (not shown in the figure). The feeding device of the shot blasting machine puts shots into the feed hopper 401, and then places the casting on the first mesh belt conveyor 3. The operation of the first motor 2 will drive the first mesh belt conveyor 3 to rotate, and the first mesh belt conveyor 3 will gradually convey the casting to the shot blasting cleaning component 4 at the left end. The shot blasting cleaning component 4 at the left end performs the first step of cleaning on the casting, and then gradually falls into the turning frame 803. The third motor 802 is started to drive the turning frame 803 to rotate, and the turning frame 803 turns the casting over and falls into the second mesh belt conveyor 10. The operation of the second motor 11 will drive it to gradually enter the shot blasting cleaning component 4 at the right end for further cleaning. In this process, since the casting can be gradually turned over, the casting can be cleaned more comprehensively.
