[0006] The metal parts to be cleaned on the surface are placed in the feed rack. In the initial state, the metal parts are blocked by the switch plate and will not fall on the cleaning slope block. The rotation of the feed motor drives the top gear to rotate, thereby driving the two-way screw shaft and the lower gear to rotate through the upper gear. The rotation of the lower gear drives the cleaning gear and the cleaning fan blade to rotate, thereby stirring the clean water in the feed rack to improve the cleaning effect. The rotation of the two-way screw shaft drives the internal threaded sleeve and the cleaning rack to rise along the feed rack.

[0043] The working principle of a metal surface impurity removal device disclosed in the present invention is as follows: a metal piece to be surface-impurity-removed is placed in a feed rack 101. In the initial state, the metal piece is blocked by a switch plate 110 and will not fall onto a cleaning slope 112. The feed motor 107 rotates to drive a top gear 108 to rotate, thereby driving a bidirectional screw shaft 102 and a lower gear 103 to rotate through an upper gear 104. The lower gear 103 rotates to drive a cleaning gear 114 and a cleaning fan blade 113 to rotate, thereby stirring the clean water in the feed rack 101 to improve the cleaning effect. The bidirectional screw shaft 102 rotates to drive an internal threaded sleeve 106 and a cleaning rack 105 along the feed rack 101. 1 is lifted and lowered.

After the cleaning slope 112 rises, it is flush with the discharge port. After the cleaning is completed, the metal piece leaves the feed rack 101 and falls onto the discharge tray 218 close to the side of the feed rack 101. The rotation of the conveyor belt 214 drives the fixed ring 216 and the discharge tray 218 to move the metal parts thereon, and the sand is transported to the impurity removal nozzle 313 through the sand pump 209, the impurity removal pipe 210 and the impurity removal branch pipe 211. The surface of the metal parts is sandblasted by the impurity removal nozzle 313, and the sand after sandblasting returns to the sand pump 209 for reuse. At the same time, when the self-rotating gear 217 is engaged with the fixed rack 215, under the action of the fixed rack 215, the self-rotating gear 217 and the discharge tray 218 rotate relative to the fixed ring 216, thereby driving the metal parts on the discharge tray 218 to rotate, so that the sandblasting is more comprehensive. At the same time, the swing motor 301 rotates to drive the motor gear 302 to rotate, thereby driving the right docking gear 306 and the right half-toothed gear 305 to rotate. The right docking gear 306 rotates to drive the left docking gear 304 and the left half-toothed gear 303 to rotate. The left half-toothed gear 303 rotates in opposite directions to the right half-toothed gear 305. When the right half-toothed gear 305 is meshed with the upper docking gear 307, the upper docking gear 307 is driven to rotate forward. When the right half-toothed gear 305 is disengaged from the upper docking gear 307, the left half-toothed gear 303 begins to mesh with the upper docking gear 307, driving the upper docking gear 307 to reverse, thereby realizing the forward and reverse switching of the upper docking gear 307, thereby driving the central rotating wheel 310 and the rotating rod 311 to continuously switch forward and reverse rotation through the horizontal transmission belt 309, thereby driving the arc rotating frame 312 to swing back and forth along the arc groove of the impurity removal box 208, thereby driving the impurity removal nozzle 313 to swing back and forth, thereby increasing the range of sandblasting, so that the sandblasting and impurity removal on the surface of the metal part are more comprehensive.When the discharge tray 218 moves the metal piece to the front of the flipping blade 202, the metal piece will be dumped onto the flipping blade 202, and the flipping gear 203 will rotate to drive the flipping blade 202 to rotate, thereby turning the metal piece over to the discharge tray 218 on the side away from the feed rack 101, and the turned metal piece is sandblasted in the same way to complete the sandblasting of the entire surface of the metal piece.
