[0035] Example

[0036] This embodiment provides a device for cleaning iron oxide on the surface of hot working die steel after quenching, which includes a mobile feeding mechanism and a cleaning mechanism.

[0037] like Figure 1 As shown, the mobile feeding mechanism includes a pair of first rails 1 and a feeding trolley 2; the pair of first rails 1 are laid on the ground; the bottom of both sides of the feeding trolley 2 are provided with first rollers 3, and the first rollers 3 are rollingly set on the pair of first rails 1; a supporting ridge 4 is fixed at the middle position of the upper surface of the feeding trolley 2, and the supporting ridge 4 is set along the direction of the first rails 1 and extends to the two ends of the upper surface of the feeding trolley 2; a driving device (not shown in the figure) is provided in the feeding trolley 2 for driving the first rollers 3 to roll.

[0039] In this embodiment, a reduction box 9 is also provided on the support frame 6, the output end of the motor 8 is connected to the input end of the reduction box 9, and the output end of the reduction box 9 is connected to the end of the steel brush roller 7; such a configuration can effectively control the rotation speed of the steel brush roller 7.
