[0027] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: through the set fixed pipe 4, when the user needs to grind and polish the workpiece, through the set fixed pipe 4, the user prepares a pipeline separately, and extends the fixed pipe 4 to a place where smoke can be discharged through the pipeline, or connects the fixed pipe 4 to the air inlet pipe of the smoke treatment machine, and the smoke treatment machine has a model of, for example, Huadu-HD-200B. Furthermore, when the user needs to polish the metal workpiece, at this time, the user starts the first hydraulic cylinder 24 to push the placement table 25 upward, so that the placement table 25 moves upward into the top of the first fixed bin 1, and then starts the second blower 15 through The second connecting pipe 16 blows air into the interior of the second fixed bin 17, and a large amount of ventilation air flowing inside the second fixed bin 17 is ejected through the plurality of first jet holes 18 provided, so that wind pressure is formed on the top of the interior of the protective bin 2 (similar to the reference document), and, through the provided storage bin 22, the storage bin 22 is started to suck air into the interior of the protective bin 2, so that the air inside the protective bin 2 enters the interior of the fixed pipe 4 through the arc-shaped cavity on one side. At the same time, the gas blown out of the first jet hole 18 enters the interior of the fixed pipe 4 along with the air flow, and then the workpiece can be polished. During polishing, debris and smoke generated by frictional heat will be generated, so the smoke and debris are blocked by wind pressure to prevent injury, and the smoke is blown into the workpiece along with the flowing air. The workpiece is taken out of the first fixed slot 5 and the first hydraulic cylinder 24 is started to move the placement table 25 downward so that the first hydraulic cylinder 24 is kept parallel to the inner bottom of the first fixed slot 5. Then, the two drive motors 8 are started to drive the threaded column 10 to rotate.

At the same time, the first blower 14 is started to pass through the first fixed slot 5. A connecting pipe 12 blows air into the interior of the movable bin 9, so that the air flow is ejected through the provided second air jet hole 28, so that the movable second air jet hole 28 blows the debris and other impurities on the top surface of the placement table 25 into the interior of the second fixed groove 19, and falls into the interior of the guide groove 21, and falls into the interior of the storage bin 22 along the slope surface of the guide groove 21 for collection, thereby completing the treatment of the debris and smoke, and then comprehensively achieving the dust-proof effect of the smoke generated during grinding and polishing, so that the wind pressure ejected through the first air jet hole 18 blocks the debris and smoke to prevent splashing and harming the users, and the flowing smoke is sucked through the storage bin 22 and discharged through the fixed pipe 4 for treatment by the smoke treatment machine to avoid pollution to the environment. At the same time,The debris generated by grinding and polishing the top surface of the placement table 25 can be processed and collected without manual cleaning, which is convenient for use and more practical.
