A shaking screen having a hoist crane is provided to exchange a screen net easily by drawing out a screen net from a screen body by a wire or a chain if the screen net is blocked up or worn out and inserting the new screen net into the screen body, by installing a screen net inserting/withdrawing unit wound with the wire or chain, at one side. In a shaking screen having a hoist crane, a screen net inserting/withdrawing unit(100) is installed at one side of the shaking screen. In the screen net inserting/withdrawing unit, the lower ends of prop frames are combined with the upper part of a support frame(120) and a footing frame(130) is combined with the upper end of the support frame. Both ends of a guide frame(140) are combined in the center of the footing frame in a longitudinal direction. A slider(160) joined with a moving motor(161) and a wheel(162) is combined with the lower part of the guide frame to slide horizontally. A winding unit(170) is joined at the lower part of the slider. A screen body combined with a screen net is installed at the upper part of the frame and propped up by a shock absorbing unit. A vibration generating unit is combined between the upper part of the frame and the lower part of the screen body. |
