[0002] In the prior art, the rust removal treatment of the workpiece surface mainly includes methods such as manual rust removal, mechanical rust removal, and chemical rust removal.

The dust falling into the accommodating cavity falls into the dust collection part through the channel and finally falls into the dust collection bucket through the first pipe. The turning action of the scraper can make the workpiece and the steel shots contact more fully, further improving the rust removal effect of the parts. The inner side surface of the side wall of the inner rotating cylinder is a regular polygon. When the inner rotating cylinder rotates, a large throwing force is generated, improving the rust removal ability and reducing the energy consumption and production cost. The setting of the second through-hole part enables the steel shots to pass through the through-hole part and fall into the steel shot collection part during the vibration of the receiving hopper. Since the volume of the steel shots is much smaller than the volume of the workpiece, the steel shots and the workpiece can be effectively separated, and at the same time, it is convenient for the secondary use of the steel shots.

[0050] The working principle of the present invention:

[0051] 1. Load the workpiece to be shot peened into the feeding hopper 21. Driven by the fourth push cylinder 23, the feeding hopper 21 rotates around the feeding hopper bracket 22. At the same time, the first push cylinder 14 pushes the rust removal machine body 11 to rotate, so that the opening of the inner rotating cylinder 111 is in a suitable position. The feeding hopper 21 pours all the workpieces into the inner rotating cylinder 111. After all the workpieces are poured, the feeding hopper 21 returns to the initial position driven by the fourth push cylinder 23;

[0052] 2. Under the combined action of the second push cylinder 124 and the third push cylinder 125, the machine cover body 121 drives the machine cover fixing frame 122 and the rotating bracket 123 to slowly rotate, combine with the rust removal machine body 11 and completely cover the accommodation cavity 1121;

[0053] 3. The feeding pipe 411 of the steel shot feeding bin 41 is pushed by the fifth push cylinder 414 to slowly rotate until it is completely communicated with the shot inlet channel 1261 of the pressure pump 126. The steel shot feeding bin 41 transports steel shots into the inner rotating cylinder 111 through the feeding pipe 411;

[0054] 4. The inner rotating cylinder 111 rotates at a high speed under the action of the first drive motor 113. At the same time, the dust (rust and steel shots with a diameter smaller than that allowed to pass through the first through-hole part) in the inner rotating cylinder 111 centrifugally drops into the accommodation cavity 1121 through the first through-hole part 1112. The dust dropping into the accommodation cavity 1121 drops into the dust collection part 1122 through the channel 1123 and finally drops into the dust collection bucket 114 through the first pipeline 1124;

[0055] 5. After all the rust on the workpiece surface is removed, the machine cover body 121 drives the machine cover fixing frame 122 and the rotating bracket 123 to rotate under the combined action of the second push cylinder 124 and the third push cylinder 125, so that the machine cover body 121 is completely separated from the rust removal machine body 11; the rust removal machine body 11 pours the workpieces and reusable steel shots (steel shots that have not passed through the through-hole part) in the inner rotating cylinder 111 into the receiving hopper 31 under the push of the first push cylinder 14;

[0056] 6. The receiving hopper 31 vibrates through the vibration motor 315, so that the workpieces are separated from the reusable steel shots. The reusable steel shots fall into the steel shot collection part 311 through the second through-hole part 3131, and finally are conveyed to the steel shot feeding bin through the second pipeline 312 and the circulation pipe 412. The staff centrally collects the separated workpieces, thus completing the whole process.
